As such, relevant intervention programs should address these aspects, and the effectiveness of such programs should be determined by assessing improvement in activities and participation. However, no patient-centred and psychometrically sound outcome measures for this purpose are available so far. Objectives The objectives of this study were to develop and to validate a new outcome measure, the PaArticular Scales, to quantify activities and participation in older individuals with joint contractures. Specific aims were (A) to operationalize the content of an International Classification of Functioning, Disability and Health-based standard set towards meaningful questions and to combine them to a questionnaire and (B) to assess the psychometric properties of the developed questionnaire, in detail to evaluate test–retest reliability, objectivity, internal consistency reliability and criterion validity. Design Operationalization was reached by an expert consensus conference and a subsequent expert Delphi survey. Psychometric properties were assessed in a cross-sectional study. Settings Nursing homes, geriatric rehabilitation facilities. Participants 23 experts (nurses, physicians, physical and occupational therapists) participated in the consensus conference and the Delphi survey. A total of 191 individuals with joint contractures (as confirmed by physician, nurse or physical therapist) between 65 and 102 years, living in nursing homes or as patients in geriatric rehabilitation were enrolled in the cross-sectional study. Methods Rasch Partial Credit Modelling. Results The consensus conference and Delphi survey resulted in a questionnaire with 86 items of the International Classification of Functioning, Disability and Health. Test–retest-reliability among those was acceptable (Cohen's weighted kappa: 0.779). The Rasch analysis revealed two independent interval-scaled scales with 24 items for the Activities scale and 11 items for the Participation scale with high internal consistency reliability. Cronbach's alpha was 0.96 for the Activities scale and 0.92 for the Participation scale. Criterion validity was −0.40 and −0.30 for the Activities scale and for the Participation scale, respectively. Conclusions The PaArticular Scales, a new patient-centred and psychometric sound outcome measures to comprehensively assess the impact of joint contractures in geriatric care, are available now. These developed scales will serve as primary outcomes in a scheduled evaluation of a complex intervention to improve participation and quality of life in nursing home residents with joint contractures.

ED - BioMed Central, T1 - Outcome measures in older persons with acquired joint contractures: a systematic review and content analysis using the ICF (International Classification of Functioning, Disability and Health) as a reference JF - BMC Geriatrics N2 - Background: Joint contractures are a common health problem in older persons with significant impact on activities of daily living. We aimed to retrieve outcome measures applied in studies on older persons with joint contractures and to identify and categorise the concepts contained in these outcome measures using the ICF (International Classification of Functioning, Disability and Health) as a reference. Methods: Electronic searches of Medline, EMBASE, CINAHL, Pedro and the Cochrane Library were conducted (1/2002-8/2012). We included studies in the geriatric rehabilitation and nursing home settings with participants aged ≥ 65 years and with acquired joint contractures. Two independent reviewers extracted the outcome measures and transferred them to concepts using predefined conceptual frameworks. Concepts were subsequently linked to the ICF categories. Results: From the 1057 abstracts retrieved, 60 studies met the inclusion criteria. We identified 52 single outcome measures and 24 standardised assessment instruments. A total of 1353 concepts were revealed from the outcome measures; 96.2 % could be linked to 50 ICF categories in the 2nd level; 3.8 % were not categorised. Fourteen of the 50 categories (28 %) belonged to the component Body Functions, 4 (8 %) to the component Body Structures, 26 (52 %) to the component Activities and Participation, and 6 (12 %) to the component Environmental Factors. Conclusions: The ICF is a valuable reference for identifying and quantifying the concepts of outcome measures on joint contractures in older people. The revealed ICF categories remain to be validated in populations with joint contractures in terms of clinical relevance and personal impact.

Some measures for the assessment of the impact of joint contractures exist. However, there is no consensus on which aspects should constantly be measured. Our objective was to develop a standard-set based on the ICF for describing functioning and disability in older individuals with joint contractures in geriatric care settings, giving special emphasis to activities and participation. Methods The ICF-based standard set was developed in a formal decision-making and consensus process and based on an adapted version of the protocol to develop ICF Core Sets. These are sets of categories from the ICF, serving as standards for the assessment, communication and reporting of functioning and health for clinical studies, clinical encounters and multi-professional comprehensive assessment and management. Results Twenty-three experts from Germany and Switzerland selected 105 categories of the ICF component Activities and Participation for the ICF-based standard set. The largest number of categories was selected from the chapter Mobility (50 categories, 47.6%). Conclusions The standard set for older individuals with joint contractures provides health professionals with a standard for describing patients’ activity limitations and participation restrictions. The standard set also provides a common basis for the development of patient-centered measures and intervention programs. The preliminary version of the ICF-based standard set will be tested in subsequent studies with regard to its psychometric properties.

ED - NCBI, T1 - Developing and piloting a multifactorial intervention to address participation and quality of life in nursing home residents with joint contractures JF - German medical science N2 - Background: Joint contractures are common problems in frail older people in nursing homes. Irrespective of the exact extent of older individuals in geriatric care settings living with joint contractures, they appear to be a relevant problem. Also, the new emphasis on the syndrome of joint contractures, e. g. by the German statutory long term care insurance, led to an increase in assessment and documentation efforts and preventive interventions in clinical care. However, more attention should be paid to the actual situation of older individuals in nursing homes with prevalent joint contractures, particularly their experience of related activity limitations and participation restrictions. Thus, the aim of this study is 1) to develop a tailored intervention to improve functioning, and especially participation and quality of life in older residents with joint contractures in nursing homes and 2) to test the feasibility of the intervention accompanied by a rigorous process evaluation. Methods: The complex intervention, which will be developed in this project follows the UK Medical Research Council (MRC) framework and integrates the perspectives of all potentially relevant user groups, from the affected individuals to clinicians and researchers. The development process will comprise a systematic literature review, reanalysis of existing data and the integration of the knowledge of the affected individuals and experts. The developed intervention including a comprehensive process evaluation will be pilot tested with residents with joint contractures in three nursing homes. Discussion: The projected study will provide a tailored intervention to improve functioning, participation and quality of life in older residents with joint contractures in nursing homes. With this focus, the intervention will support patient relevant outcomes. The pilot study including process evaluation will offer a first opportunity to indicate the size of the intervention’s effect and prepare further studies.

Study Design and Setting This was a cross-sectional study conducted in four specialized outpatient dizziness clinics in Germany, United States, Jordan, and Saudi Arabia. Results A total of 453 participants were included in the study. The Rasch analysis revealed two separate subscales. Subscale 1 items included focusing attention, lying down, standing, bending, lifting and carrying objects, and sports. Subscale 2 items included walking long distances, climbing, running, moving around within buildings other than home, using transportation, and driving. The Pearson product–moment correlation between the Dizziness Handicap Inventory and the summary score of the VAP subscale 1 was 0.66 and was 0.64 for subscale 2. Conclusion Owing to its shortness and intercultural adaptability, the new two-scale version of the VAP questionnaire lends itself to clinical practice and research across countries to estimate the effect of vertigo and dizziness on activity limitation and participation restrictions. Psychometrically sound summary scores can be calculated. More extended versions of the VAP can be used for comprehensive clinical assessment where summary scores are not needed or a more detailed documentation is warranted.

ED - Taylor and Francis online, T1 - Patients' view on health-related aspects of functioning and disability of joint contractures: a qualitative interview study based on the International Classification of Functioning, Disability and Health JF - Disability and Rehabilitation N2 - Purpose: The aim of this study was to identify health-relevant aspects of functioning and disability of persons aged 65 years or older with joint contractures, to link the findings to corresponding ICF categories and to describe the patients’ perspective. Methods: We conducted 43 qualitative, semi-structured, face-to-face interviews with affected persons in two different locations (Witten, Munich) and in three different settings. Data were analyzed using the “meaning condensation procedure” and then linked to ICF categories. Results: From all interviews a total of 2499 single meaning-concepts were extracted which were linked to 324 different ICF categories. The participants in all settings mainly reported problems related to “Mobility of a single joint (b710)”, “Sensation of pain (b280)” and problems related to “Walking (d450)”. Almost all participants reported “Products and technology for personal indoor and outdoor mobility and transportation (e120)” as a relevant environmental factor. Conclusions: From the patients’ perspective, joint contractures have an impact on multifaceted aspects of functioning and disability, mainly body functions, environmental factors and activities and participation. The results of this study will contribute to the development of a standard instrument for measuring functioning, disability and health-relevant aspects for patients with joint contractures. Implications for Rehabilitation Joint contractures are a major cause for the development of disability in older people. Patients’ perspectives and their personal experiences have to be considered when assessing the impact of joint contractures. The International Classification of Functioning, Disability and Health (ICF) is an appropriate framework for describing the patients’ multifaceted experience of joint contractures.

ED - Springer Link, T1 - Impact of vertigo and dizziness on self-perceived participation and autonomy in older adults: Results from the KORA-Age study JF - Quality of life research N2 - Purpose The impact of vertigo and dizziness on healthy ageing, and especially on participation, is not fully understood. The objective of this study was to investigate the association of vertigo and dizziness with self-perceived participation and autonomy in older non-institutionalised individuals, adjusted for the presence of other health conditions. Specifically, we wanted to investigate the different effects of vertigo and dizziness on specific components of participation, i.e. restrictions in indoor and outdoor autonomy, family role, social life and relationships, and work and education. Methods Data originate from the second wave of the German KORA-Age cohort study collected in 2012. Participation and autonomy was investigated with the Impact on Participation and Autonomy Questionnaire. We used robust regression to analyse the association of vertigo and dizziness with self-perceived participation and autonomy adjusted for covariates. Results A total of 822 participants (49.6 % female) had a mean age of 78.1 years (SD 6.39). Participation and autonomy were significantly lower in participants with vertigo and dizziness across all domains. Adjusted for age, sex, and chronic conditions, vertigo and dizziness were significantly associated with participation restrictions in all domains except social life and relationships. Conclusion The results of our study indicate that vertigo and dizziness contribute to restrictions in participation and autonomy in individuals of older age. Recognising vertigo and dizziness as independent contributors to loss of autonomy and decreased chances for independent living may create new options for patient care and population health, such as the designing of complex interventions to maintain participation and autonomy.

ED - Oxford Academic, T1 - Burden of disability attributable to vertigo and dizziness in the aged: results from the KORA-Age study JF - European journal of public health N2 - Background: Complaints of vertigo and dizziness are common in primary care in the aged. They can be caused by distinct vestibular disorders, but can also be a symptom in other conditions like non-vestibular sensory loss, vascular encephalopathy or anxiety. The aim of this study was to investigate the specific contribution of vertigo and dizziness to the total burden of disability in aged persons when controlling for the presence of other health conditions. Methods: Data originate from the MONICA/KORA study, a population-based cohort. Survivors of the original cohorts who were 65 years and older were examined by telephone interview in 2009. Disability was assessed with the Health Assessment Questionnaire. Logistic regression was used to adjust for potential confounders and additive regression to estimate the contribution of vertigo and dizziness to disability prevalence. Results: Adjusted for age, sex and other chronic conditions, vertigo and dizziness were associated with disability (odds ratio 1.66, 95% confidence intervals 1.40–1.98). In both men and women between 65 and 79 years, vertigo and dizziness were among the strongest contributors to the burden of disability with a prevalence of 10.5% (6.6 to 15.1) in men and 9.0% (5.7 to 13.0) in women. In men, this effect is stable across all age-groups, whereas it decreases with age in women. Conclusions: Vertigo and dizziness independently and relevantly contribute to population-attributable disability in the aged. They are not inevitable consequences of ageing but arise from distinct disease entities. Careful management of vertigo and dizziness might increase population health and reduce disability.

ED - Springer Link, T1 - Health services utilization of patients with vertigo in primary care: a retrospective cohort study JF - Journal of neurology N2 - Vertigo and dizziness count among the most frequent symptoms in outpatient practices. Although most vestibular disorders are manageable, they are often under- and misdiagnosed in primary care. This may result in prolonged absence from work, increased resource use and, potentially, in chronification. Reliable information on health services utilization of patients with vertigo in primary care is scarce. Retrospective cohort study in patients referred to a tertiary care balance clinic. Included patients had a confirmed diagnosis of benign paroxysmal positional vertigo (BPPV), Menière’s disease (MD), vestibular paroxysmia (VP), bilateral vestibulopathy (BVP), vestibular migraine (VM), or psychogenic vertigo (PSY). All previous diagnostic and therapeutic measures prior to the first visit to the clinic were recorded. 2,374 patients were included (19.7 % BPPV, 12.7 % MD, 5.8 % VP, 7.2 % BVP, 14.1 % VM, 40.6 % PSY), 61.3 % with more than two consultations. Most frequent diagnostic measures were magnetic resonance imaging (MRI, 76.2 %, 71 % in BPPV) and electrocardiography (53.5 %). Most frequent therapies were medication (61.0 %) and physical therapy (41.3 %). 37.3 % had received homoeopathic medication (39 % in BPPV), and 25.9 % were treated with betahistine (20 % in BPPV). Patients had undergone on average 3.2 (median 3.0, maximum 6) diagnostic measures, had received 1.8 (median 2.0, maximum 8) therapies and 1.8 (median 1.0, maximum 17) different drugs. Diagnostic subgroups differed significantly regarding number of diagnostic measures, therapies and drugs. The results emphasize the need for establishing systematic training to improve oto-neurological skills in primary care services not specialized on the treatment of dizzy patients.

The aims of this study were to determine the association between midlife physical activity and late-life disability and to investigate gender-specific differences. Method This data originates from the KORA-Age cohort, a follow-up in 2008 of the MONICA (Multinational Monitoring of Trends and Determinants in Cardiovascular Diseases)/KORA (Cooperative Health Research in the Region of Augsburg) S1–S4 surveys (1984–2001) situated in Augsburg, a city in Southern Germany. We applied a multivariable hurdle model to investigate the association of physical activity and disability. Results We analysed 3333 persons with a mean follow-up of 18 ± 5.5 years. Using hurdle models, moderate activity and high activity had a protective effect on the occurrence of disability (OR (odds ratio) = 0.80 and 0.73), but not on severity (i.e. number of limitations). We observed a strong gender-specific difference in this association, with men benefitting more from exercise. Conclusion Elevated physical activity reduces the risk of becoming disabled and postpones the onset of disability by several years, but we could not show an effect on the severity of disability.

JF - Quality of life research N2 - Purpose Visual height intolerance (vHI) occurs when a trigger causes the apprehension of losing balance and falling. Depending on the severity of vHI, an avoidance behavior may develop in about 50 % of the thus afflicted, and it can have considerable impact on their daily life and interpersonal interactions. It seems obvious that such experiences may be impairing and distressing, but this has not yet been examined systematically. Objective of this study was to examine the consequences of vHI for quality of life. Methods A qualitative, phenomenological exploratory approach was chosen. Individual face-to-face interviews were conducted with individuals who had reported in a previous study that they were susceptible to vHI. The interview transcripts were segregated into distinct meaning units, which were used to create a coding guideline with meta- and subcodes. Meaning units were then systematically extracted and assigned to the appropriate codes. Weights and links were used to assign priorities for interpretation. Results Eighteen participants were interviewed (mean age 53, range 30–73; 11 females). Data analysis resulted in 29 meta-codes and 115 subcodes. Responses indicated that vHI can be very disabling and has a relevant impact on quality of life and daily activities of the affected persons, including their family life and behavior towards partner, children and friends. Conclusion Relevant topics for further quantitative studies were identified, for example, strategies of compensation and the influence of vHI on family life. Other quantitative studies should determine whether comorbidities and the typologies found in this study have consequences for individual therapeutic approaches.

Results A total of 534 (51.5%) of 1,037 participants were characterized as disabled. Disabled participants were on average 4.5 years older than those who were not disabled. Crude associations of left-axis deviation, ventricular conduction defects, atrial fibrillation, and QT prolongation with disability status were significant (P < 0.05). In models controlled for age and sex, these effects remained constant except for QT prolongation. In the models adjusted for the minimal sufficient adjustment set (consisting of the variables sex, physical activity, age, obesity, diabetes, education, heart diseases, income, lung diseases, and stroke) identified by a directed acyclic graph (DAG), no significant association could be shown. Conclusion Associations between specific ECG findings and disability were found in unadjusted analysis and logistic models adjusted for age and sex. However, when adjusting for other possible confounders identified by the DAG, all these associations were no longer significant. It is important to adequately identify confounding in such settings.

Due to the lack of appropriate patient reported outcome measures (PRO), the extent of limitations and restrictions is mostly unknown. The International Classification of Functioning, Disability and Health (ICF) is a conceptual framework and classification to evaluate all aspects of health and disability. An ICF-based measure, the Vestibular and Participation Measure (VAP), was recently proposed. Also, an ICF Core Set for vertigo, dizziness and balance disorders was developed to describe what aspects of functioning should be measured. This study protocol describes the development and cross-cultural validation of a new measure, the VAP-extended (VAP-e), based on VAP and ICF Core Set on three continents. To determine objectivity and cross-cultural validity of the VAP and to find potentially redundant items, Rasch models will be used. The VAP-e will be created by modifying or adding items from the Activities and Participation and Environmental Factors component of the ICF Core Set. Reliability, objectivity and responsiveness of the VAP-e will be tested. KW - Dizziness KW - Vertigo KW - Quality of life Y1 - 2012 ER - TY - JOUR A1 - Müller, Martin A1 - Fischer, U.

ED - Springer Nature, T1 - Impact of joint contractures on functioning and social participation in older individuals--development of a standard set (JointConFunctionSet) JF - BMC Geriatrics N2 - Background Free movement of the limbs is a prerequisite of mobility and autonomy in old age. Joint contractures, i.e. restrictions in full range of motion of any joint due to deformity, disuse or pain, are common problems of frail older people, particularly in nursing home residents. Contractures are among the most unexplored and underreported syndromes in clinical and homecare settings. Epidemiological studies indicate a wide range of prevalence of joint contractures in older individuals between 20% and 80%. This variation is due to different definitions of contracture and varying diagnostic criteria or data collection methods, different research settings, sample size and study participants? characteristics. The aetiology of joint contractures is multifaceted. In older people contractures may be caused by a variety of health conditions and situations, but immobility due to an acute injury or disease seems to be the major risk factor. Upper limb joint contractures may result in loss of ability to dress or eat independently while lower limb contractures may lead to instability and inability to walk independently and higher risk of bed confinement. Joint contractures further increase the risk of other adverse patient outcomes like pain, pressure ulcers and risk of falls. Thus, joint contractures are a major cause for excess disability in older people with a significant impact on overall quality of life and functioning. Preventive and rehabilitation interventions targeting joint contractures may decrease morbidity, increase functioning and quality of life, and, ultimately, prevent long-term disability. In the United States of America, presence of joint contractures is an established indicator of quality of care in nursing facilities. In Germany, joint contracture risk assessment and prevention have recently been defined as a quality indicator of nursing home care that should be regularly monitored by experts from the statutory health insurance system. Nursing homes are obliged to report whether they regularly assess the risk of joint contracture and administer relevant preventive measures. In clinical settings, joint contractures are assessed by measuring the range of motion. However, from a patient- and nursing-oriented perspective the relevance of a systematic registration of contractures in care-dependent older people is unclear unless their impact on functioning is understood. Contracture assessment is only an intermediate step in the evaluation of patient-relevant outcomes such as quality of life, functioning, and the ability to participate in everyday life and social participation. Arguably, a clinical definition of joint contracture is difficult because the contracture?s severity is determined by the consequences on activities of daily living, quality of life and social participation. In addition, there is no consensus on aspects most relevant to the affected individuals. A variety of functional measures is currently used for the assessment and evaluation of geriatric patients. To date, there is no consensus on common concepts for the choice of outcome measures specifically for evaluating the impact of interventions targeted on joint KW - Contractures KW - Aged KW - 80 and over KW - disabled persons KW - outcome assessment KW - geriatric rehabilitation Y1 - 2018 ER - TY - JOUR A1 - Müller, Martin ED - Academic onFile, T1 - Identification of aspects of functioning, disability and health relevant to patients experiencing vertigo: a qualitative study using the international classification of functioning, disability and health JF - Health and quality of life outcomes N2 - Background Vertigo and dizziness are among the most common health problems in medical practice [1, 2, 3, 4, 5]. Vertigo and dizziness include both consequences of disease as well as definable disease entities such as benign paroxysmal positional vertigo, Meniere?s disease, or vestibular migraine. Irrespective of the various causes and underlying health conditions, vertigo and dizziness have significant impact on functioning and overall quality of life of the affected individuals To give some examples, the most common peripheral-vestibular disorder benign paroxysmal positioning vertigo - which is also the most frequent type of vestibular disorder - causes brief rotatory vertigo attacks, mainly triggered by rapid head movements, e.g. when turning around in the bed or lacing shoes. Central-peripheral disorders, which may be caused by brain ischemia, multiple sclerosis, or other permanent or transient brain lesions, can make vertigo attacks lasting from minutes to even weeks [6]. In addition, vertigo and dizziness are a considerable burden to economy and health care [4, 7, 8]. Precondition of effective management and treatment of potentially disabling conditions like vertigo is - besides careful diagnosis of the underlying condition -the assessment of outcomes which are relevant to the patient. This is not only important to monitor treatment effects but also to set goals and to plan therapy [6]. As summarized by Morris et al. [9] outcome measures in vertigo vary by the entities they are addressing, such as subjective experience of disability or signs and symptoms. Most of them reflect either the patients? or health professionals? experience. As an example, the frequently used Dizziness Handicap Inventory [10] addresses the patients? experience of the consequences of vertigo on daily living. Most outcome measures are developed and validated on the basis of empirical findings or professional experience [11]. However, none of them refer to a common theoretical framework. A theoretical framework is fundamental for defining an Outcome measurement and helps to ensure that the whole potential spectrum of issues is reflected [12]. In addition to the lack of theoretical foundation there is still no agreement on standards used to measure outcomes in patients with vertigo. This is illustrated by a recently published Cochrane Review in the field of vestibular rehabilitation which noted 15 different outcome measures of patients? complaints in 21 studies [13]. To address both these issues, the Integrated Center for Research and Treatment of Vertigo, Balance and Ocular Motor Disorders ( IFB LMU ) at the Ludwig-Maximilians-Universität in Munich set up a project that aims to develop an international standard for the description of functioning and disability in patients with vertigo and dizziness based on the International Classification of Functioning, Disability and Health (ICF). With the ICF, which is part of the family of international classifications of the World Health Organisation (WHO), there is a common theoretical framework for describing and measuring health and disability. The ICF models the individuals' functioning and health as a complex interaction between a health condition.

Design: Prospective multi-centre cohort study. Patients: Patients receiving rehabilitation interventions for musculoskeletal, neurological or cardiopulmonary injury or disease in acute hospitals. Methods: Functioning and contextual factors were coded using the ICF. The criterion for selecting candidate categories for the brief ICF Core Sets was based on their ability to discriminate between patients with high or low functioning status. Discrimination was assessed using multivariable regression models, the independent variables being all of the ICF categories of the respective comprehensive ICF Core Set. Analogue ratings of overall functioning as reported by patients and health professionals were used as dependent variables. Results: A total of 391 patients were included in the study (91 neurological, 109 cardiopulmonary, 191 musculoskeletal), mean age 63.4 years, 50.1% female. Selection yielded 33 categories for neurological, 31 for cardiopulmonary, and 30 for musculoskeletal.

Design: Multi-centre cohort study. Patients: A total of 397 patients (50% female, mean age 63 years) from 5 hospitals in Austria, Switzerland and Germany. Methods: A semi-structured questionnaire was used to assess patient goals and goal achievement. Overall functioning from the patients' and health professionals' perspective was assessed on a numerical rating scale. Improvement in functioning was calculated using a residualized gain score. Association between goal achievement and improvement in overall functioning was assessed with logistic regression. Results: A total of 397 patients reported achievement of at least 1 goal. Eighty-eight percent of the goals were translated into categories of the ICF. Logistic regression analyses revealed significant association between goal achievement and overall functioning. Conclusion: The ICF might be useful to identify and structure patient's goals in acute hospital care. The association between goal achievement and improved functioning underlines that it is essential to involve the patient in the process of planning rehabilitation interventions in acute hospitals.

Rounding off the Parts 1 and 2 of this publication nomograms, based on dimensionless parameters, can be developed to predict the sound radiation of light weight slabs. Hereby different sets of geometry as well as different configurations of ceilings can be studied in order to describe the acoustical and dynamical behaviour of wooden ceilings.

Part 1: Aspects of Numerical Modeling, Model Updating and Parametric Studies using the Buckingham π -Theorem T2 - Deutsche Gesellschaft für Akustik e.V. (ed.), AIA-DAGA N2 - In order to set up guidelines for the design of light-weighted ceilings for timber constructions to be used by engineers in practice, investigations based on both measurements and numerical models have been carried out [1, 2, 3]. The setup and the calibration of the numerical model of the structure are outlined briefly. A semi-analytical approach for the prediction of radiated sound is presented, which is based on Integral Transform Methods. The method can be applied in the post processing of a Finite Element computation. Thus as a first step the structure, consisting of a timber slab, a floating floor and a suspended ceiling, is built up in a Finite Element model, where the material properties of wood and the characteristics of the system are considered. The model is parameterized in order to enable computations with varying geometry and material parameters and calibrated with the help of measurements using model updating techniques. The velocity pattern resulting out of the FEM computation is transformed from the spatial into the wavenumber domain and from the time into the frequency domain using Fourier Transform Methods. Applying this velocity pattern as a boundary condition to the Helmholtz Equation, which results out of the Fourier Transform of the wave equation, the wavenumbers, which fulfil the radiation condition, can be selected and the pressure field in the adjacent acoustic fluid can be computed. Due to the properties of the Fourier-Transform the radiated sound power can be calculated efficiently in the transformed domain out of pressure and velocity. In a second part of the contribution the model for the air cushion in the suspended ceiling is discussed, where a FSI-model for the acoustic fluid and the structure is compared against engineering approaches using simplifications concerning mass distribution and transfer impedances between the individual nodes at the interface KW - Schallmesstechnik KW - Holzbau Y1 - 2013 ER - TY - CHAP A1 - Kohrmann, M.

In this contribution the setup and the calibration of the numerical model of the structure as well as the prediction of radiated sound are discussed, where a special focus is set on a dimensionless description in order to deduce information for a wide range of system’s specifications.

The model is parameterized in order to enable computations with varying geometry and material parameters. After calibrating the FE-model with the help of measurements using model updating techniques dimensionless parameters are defined based on the Buckingham-π- Theorem and computations are carried out in order to specify guidelines for various systems.

A1 - Schanda, Ulrich T1 - Modelling the Sound Transmission across Junctions of Building Components by Energy Influence Coefficients T2 - European Association for Structural Dynamics (ed.), EURODYN N2 - A trend towards lightweight structures, e.g. timber structures, is noticeable in civil engineering, which implies the necessity to predict vibroacoustic characteristics like the transmission of structure-borne sound in order to fulfil requirements regarding serviceability. This contribution focuses on the investigation of junctions of building components e.g. between wall and ceiling. It is part of a joint research project with the aim to catalogue the coupling for a variety of junctions. The resulting database may serve to predict the transmission of structure-borne sound which is typically carried out either using a Finite Element (FEM) approach, suitable for the low frequency range, or by means of energy methods like the Statistical Energy Analysis (SEA) for the high frequency range. Therefore the so-called mid frequency gap emerges, which is examined and attempted to be closed. In this context SEA-averaging techniques are applied in the postprocessing of FEM calculations to obtain an adapted “SEAlike” approach. By varying the subsystems to be excited it is possible to determine Energy Influence Coefficients (EIC), which describe the specific energy content of the different subsystems with respect to the input power. Using this hybrid approach vibroacoustic predictions can be performed also in the mid frequency range. Inverting the EIC-matrix Coupling Loss Factors as well as Damping Loss Factors of the different subsystems can be calculated if the subsystem definition fulfils the SEA-requirements. The application of the method in combination to a classical SEA calculation and to laboratory measurements is presented. KW - Schallmesstechnik KW - Holzbau Y1 - 2014 ER - TY - CHAP A1 - Völtl, R.

In order to understand the vibration behaviour of and the sound transmission through the layers of the constructions the coupling between them was investigated. The transfer function from the point of excitation to a pattern of receiving positions located on each of the layers of the construction was measured using a swept sine excitation. As a result, the frequency range of decoupling between the base floor and the floating floor and between the base floor and the suspended ceiling could be identified and the individual vibration behavior analyzed. The measurements also included the radiated sound power from the suspended ceiling.

Several studies have examined the independent effects of single diseases; however, little research has focused on interaction between diseases. The purpose of this study was to assess the impact of six self-reported major conditions and their combinations on HRQL measured by the EQ-5D. Methods The EQ-5D was administered in the population-based KORA-Age study of 4,565 Germans aged 65 years or older. A generalised additive regression model was used to assess the effects of chronic conditions on HRQL and to account for the nonlinear associations with age and body mass index (BMI). Disease interactions were identified by a forward variable selection method. Results The conditions with the greatest negative impact on the EQ-5D index were the history of a stroke (regression coefficient -11.3, p < 0.0001) and chronic bronchitis (regression coefficient -8.1, p < 0.0001). Patients with both diabetes and coronary disorders showed more impaired HRQL than could be expected from their separate effects (coefficient of interaction term -8.1, p < 0.0001). A synergistic effect on HRQL was also found for the combination of coronary disorders and stroke. The effect of BMI on the mean EQ-5D index was inverse U-shaped with a maximum at around 24.8 kg/m2. Conclusions There are important interactions between coronary problems, diabetes mellitus, and the history of a stroke that negatively affect HRQL in the older German population. Not only high but also low BMI is associated with impairments in health status. KW - Aging KW - Multimorbidity KW - KORA Study Y1 - 2011 ER - TY - JOUR A1 - Kirsch, R. A1 - Bergmann, A.

However, current healthcare has several shortcomings regarding mobility sustainment of older adults, namely a narrow focus on the underlying pathology, fragmentation of care across services and health professions and deficiencies in personalising care based on patients’ needs and experiences. A tailored healthcare strategy targeted at mobility of older adults is still missing. Objective The objective is to develop multiprofessional care pathways targeted at mobility sustainment and social participation in patients with vertigo/dizziness/balance disorders (VDB) and osteoarthritis (OA) . Methods Data regarding quality of life, mobility limitation, pain, stiffness and physical function is collected in a longitudinal observational study between 2017 and 2019. General practitioners (GPs) recruit their patients with VDB or OA. Patients who visited their GP in the last quarter will be identified in the practice software based on VDB and OA-related International Classification of Diseases 10th Revision. Study material will be sent from the practice to patients by mail. Six months and 12 months after baseline, all patients will receive a mail directly from the study team containing the follow-up questionnaire. GPs fill out questionnaires regarding patient diagnostics, therapy and referrals. Ethics and dissemination The study was approved by the ethical committee of the Ludwig-Maximilians-Universität München and of the Technische Universität Dresden. Results will be published in scientific, peer-reviewed journals and at national and international conferences. Results will be disseminated via newsletters, the project website and a regional conference for representatives of local and national authorities.

To investigate the association of those services and patient-relevant outcomes, a specific instrument to document the utilization of those services is needed. The purpose of this study was to develop such a questionnaire administered to caregivers in epidemiological studies or patient registries in Germany. Methods The development process of the RECAPDOC questionnaire was carried out in three steps. Step 1 consisted of a systematic literature review and an online-based expert survey to define the general content. Step 2 was an expert interview to evaluate the preliminary content of the questionnaire. Step 3 was a pretest including cognitive interviews with caregivers. After each step, the results were combined into a new version of the questionnaire. Results The first version of the questionnaire included items on utilization of medical care, medical aids, nursing and therapeutic care. The results of the expert interview led to the integration of five new items and the modification of six other items. The pretest led to some minor modifications of the questionnaire since it was rated as feasible and acceptable. The final questionnaire consisted of 29 items covering the domains “living situation”, “social insurance status”, “utilisation of home health care”, “domestic services”, “outpatient health care”, “specific diagnostic measures”, “adaptive technologies”, “medical aids” and “utilization of therapies”. Also the experience of family support and multidisciplinary collaboration of health professionals is covered. Conclusions The developed questionnaire is a first step to make the situation of patients with disorders of consciousness in the long-term care setting accessible for evaluation in epidemiological studies and in the context of patient registries. However, further reliability and validity studies are needed.

This study aimed to evaluate the effect of intervention methods on the guideline adherence of primary care providers (PCPs). Methods The studies selected through a systematic search in Medline and Embase were categorised according to intervention schemes and outcome indicator categories. Harvest plots and forest plots were applied to integrate results. Results The 36 studies covered six intervention schemes, with single interventions being the most effective and distribution of materials the least. The harvest plot displayed 27 groups having no effect, 14 a moderate and 21 a strong effect on the outcome indicators in the categories of knowledge transfer, diagnostic behaviour, prescription, counselling and patient-level results. The forest plot revealed a moderate overall effect size of 0.22 [0.15, 0.29] where single interventions were more effective (0.27 [0.17, 0.38]) than multifaceted interventions (0.13 [0.06, 0.19]). Discussion Guideline implementation strategies are heterogeneous. Reducing the complexity of strategies and tailoring to the local conditions and PCPs’ needs may improve implementation and clinical practice.

We developed the Participation Enabling CAre in Nursing (PECAN) intervention, a complex intervention to enable nurses to promote participation in nursing home residents with joint contractures. The aim of this study was to examine the feasibility of the implementation strategy and to identify enablers and barriers for a successful implementation. Methods The implementation of PECAN was investigated in a 6-month pilot cluster-randomised controlled trial (c-RCT). As a key component of the implementation strategy, nominated nurses were trained as facilitators in a one-day workshop and supported by peer-mentoring (visit, telephone counselling). A mixed-methods approach was conducted in conjunction with the pilot trial and guided by a framework for process evaluations of c-RCTs. Data were collected using standardised questionnaires (nursing staff), documentation forms, problem-centred qualitative interviews (facilitators, therapists, social workers, relatives, peer-mentors), and a group discussion (facilitators). A set of predefined criteria on the nursing home level was examined. Quantitative data were analysed using descriptive statistics. Qualitative data were analysed using directed content analysis. Results Seven nursing homes (n = 4 intervention groups, n = 3 control groups) in two regions of Germany took part in the study. Facilitators responded well to the qualification measures (workshop participation: 14/14; workshop rating: “good”; peer-mentor visit participation: 10/14). The usage of peer-mentoring via telephone varied (one to seven contacts per nursing home). Our implementation strategy was not successful in connection with supplying the intervention to all the nurses. The clear commitment of the entire nursing home and the respect for the expertise of different healthcare professionals were emphasised as enablers, whereas a lack of impact on organisational conditions and routines and a lack of time and staff competence were mentioned as barriers. Conclusion The PECAN intervention was delivered as planned to the facilitators but was unable to produce comprehensive changes in the nursing homes and subsequently for the residents.

T1 - Monitoring temperature evolution and drying of coating on a single fluidized particle by infrared thermography JF - Powder Technology N2 - Coating is an important step for the protection of drugs and flavors in the pharmaceutical and food industry. This paper presents a method for the experimental investigation of the coating process of a single freestream-fluidized particle by an infrared camera. The coating is dispersed by a nozzle with ultrasonic fluid atomization, allowing constant droplet size at different spray rates. The temperature of the fluidized particle was measured online by an infrared camera. The application of the coating on the particle in a spray cycle and the subsequent solvent vaporization is linked to the temperature and hence monitored during the whole coating process. The cyclic coating process of a Wurster coater is hence reproduced. The temperature evolution for different coating amounts in a single spray cycle, for different particle sizes, materials and temperature levels is monitored. A micro-computed tomography image shows the result of the levitator coating, giving a homogeneous layer.

However, disentangling stressor effects and identifying relevant stressor-effect-relationships in complex environmental settings remain major challenges. By combining state-of-the-art methods from ecotoxicology and aquatic ecosystem analysis, we aimed here to disentangle the effects of multiple chemical and non-chemical stressors along a longitudinal land use gradient in a third-order river in Germany. We distinguished and evaluated four dominant stressor categories along this gradient: (1) Hydromorphological alterations: Flow diversity and substrate diversity correlated with the EU-Water Framework Directive based indicators for the quality element macroinvertebrates, which deteriorated at the transition from near-natural reference sites to urban sites. (2) Elevated nutrient levels and eutrophication: Low to moderate nutrient concentrations together with complete canopy cover at the reference sites correlated with low densities of benthic algae (biofilms). We found no more systematic relation of algal density with nutrient concentrations at the downstream sites, suggesting that limiting concentrations are exceeded already at moderate nutrient concentrations and reduced shading by riparian vegetation. (3) Elevated organic matter levels: Wastewater treatment plants (WWTP) and stormwater drainage systems were the primary sources of bioavailable dissolved organic carbon. Consequently, planktonic bacterial production and especially extracellular enzyme activity increased downstream of those effluents showing local peaks. (4) Micropollutants and toxicity-related stress: WWTPs were the predominant source of toxic stress, resulting in a rapid increase of the toxicity for invertebrates and algae with only one order of magnitude below the acute toxic levels. This toxicity correlates negatively with the contribution of invertebrate species being sensitive towards pesticides (SPEARpesticides index), probably contributing to the loss of biodiversity recorded in response to WWTP effluents. Our longitudinal approach highlights the potential of coordinated community efforts in supplementing established monitoring methods to tackle the complex phenomenon of multiple stress.

However, current healthcare has several shortcomings regarding mobility sustainment of older adults, namely a narrow focus on the underlying pathology, fragmentation of care across services and health professions and deficiencies in personalising care based on patients’ needs and experiences. A tailored healthcare strategy targeted at mobility of older adults is still missing. Objective The objective is to develop multiprofessional care pathways targeted at mobility sustainment and social participation in patients with vertigo/dizziness/balance disorders (VDB) and osteoarthritis (OA) . Methods Data regarding quality of life, mobility limitation, pain, stiffness and physical function is collected in a longitudinal observational study between 2017 and 2019. General practitioners (GPs) recruit their patients with VDB or OA. Patients who visited their GP in the last quarter will be identified in the practice software based on VDB and OA-related International Classification of Diseases 10th Revision. Study material will be sent from the practice to patients by mail. Six months and 12 months after baseline, all patients will receive a mail directly from the study team containing the follow-up questionnaire. GPs fill out questionnaires regarding patient diagnostics, therapy and referrals. Ethics and dissemination The study was approved by the ethical committee of the Ludwig-Maximilians-Universität München and of the Technische Universität Dresden. Results will be published in scientific, peer-reviewed journals and at national and international conferences. Results will be disseminated via newsletters, the project website and a regional conference for representatives of local and national authorities.

Barriers and facilitators: an integrative review JF - BMJ Open N2 - Background: Robots in healthcare are gaining increasing attention; however, their implementation is challenging due to the complexity of both interventions themselves and the contexts in which they are implemented. The objective of this integrative review is to identify barriers to and facilitators of the implementation of robotic systems in nursing. Methods: Articles published from 2002 to 2019 reporting on projects to implement robotic devices in nursing care were searched on Medline (via PubMed), CINAHL and databases on funded research projects (Community Research and Development Information Services and Technische Informationsbibliothek) and in journals for robotic research in November 2017 and July 2019 for an update. No restrictions regarding study designs were imposed. All included articles underwent quality assessments with design-specific critical appraisal tools. Barriers to and facilitators of implementation were classified using the Context and Implementation of Complex Interventions framework. Results: After removing all duplicates, the search revealed 11 204 studies, of which 17 met the inclusion criteria and were included in the synthesis. The majority of the studies dealt with the implementation of robots designed to support individuals, either living at home or in nursing homes (n=11). The studies were conducted in Europe, the USA and New Zealand and were carried out in nursing homes, individual living environments, hospital units and laboratories. The quality of reporting and quality of evidence were low in most studies. The most frequently reported barriers were in socioeconomic and ethical domains and were within the implementation outcomes domain. The most frequently reported facilitators were related to the sociocultural context, implementation process and implementation strategies. Discussion: This review identified barriers to and facilitators of the implementation of robotic devices in nursing within different dimensions. The results serve as a basis for the development of suitable implementation strategies to reduce potential barriers and promote the integration of elements to facilitate implementation.

Ziel: Ziel war es zu untersuchen, wie aus Sicht von Führungspersonen und Hygienefachkräften in der Pflege die stationäre Akutversorgung durch die Pandemiesituation beeinflusst wurde und welche Implikationen sich daraus für die Zukunft ergeben. Methoden: Qualitative Studie bestehend aus semistrukturierten Interviews mit fünf Verantwortlichen des leitenden Pflegemanagements und drei Hygienefachkräften in vier Krankenhäusern in Deutschland. Die Interviews wurden mittels qualitativer Inhaltsanalyse ausgewertet. Ergebnisse: Die Befragten beschrieben den auf die prioritäre Versorgung von COVID-19-Fällen hin umstrukturierten Klinikalltag. Herausforderungen waren Unsicherheit und Angst bei den Mitarbeiter_innen, relative Ressourcenknappheit von Material und Personal und die schnelle Umsetzung neuer Anforderungen an die Versorgungleistung. Dem wurde durch gezielte Kommunikation und Information, massive Anstrengungen zur Sicherung der Ressourcen und koordinierte Steuerung aller Prozesse durch bereichsübergreifende, interprofessionelle Task Forces begegnet. Schlussfolgerungen: Die in der COVID-19-Pandemie vorgenommenen Anpassungen zeigen Entwicklungspotenziale für die zukünftige Routineversorgung auf, z. B. könnten neue Arbeits- und Skill Mix-Modelle aufgegriffen werden. Für die Konkretisierung praktischer Implikationen sind vertiefende Analysen der Daten mit zeitlichem Abstand erforderlich. N2 - Background: The COVID-19-pandemic is an unprecedented, exceptional situation and necessitates numerous adaptations of structures and processes in the acute inpatient setting. Aim: The aim of this study was to explore how acute inpatient care was influenced by the pandemic and which implications may result for the future from nursing managers’ and hygiene specialists’ point of view. Methods: Qualitative study based on semi-structured interviews with five nursing managers and three hygiene specialists in four German acute care hospitals. Interviews were interpreted by using content analysis. Results: Interviewees described how everyday routines in their hospitals were adapted to the prioritized care for COVID-19 patients. Main challenges were uncertainty and anxiety among staff, relative scarcity of equipment and workforce resources and rapid implementation of new requirements for treatment capacities. This was addressed by targeted communication and information, large efforts to ensure resources and coordinated control of all processes by cross-department, interprofessional task forces. Conclusions: Adaptations made to the structures and procedures of care delivery during the pandemic hold potential for future improvements of routine care, e. g. new workplace and skill mix models. To identify detailed practical implications, a renewed and deepened data analysis is needed at a later point of time, with a larger distance to the period of the pandemic.

Ergebnisse einer Befragung wissenschaftlicher Nachwuchskräfte an unterschiedlichen Etappen des Karriereweges JF - Lehren & Lernen im Gesundheitswesen N2 - Die Pflegewissenschaft in Deutschland steht vor der Herausforderung, wissenschaftliche Strukturen und Karrierewege auszubilden. Erschwert wird dies durch einen Mangel an wissenschaftlichem Nachwuchs, der das Potential hat, pflegewissenschaftliche Professuren mit wissenschaftlicher Exzellenz und praktischer Erfahrung zu füllen. Ziel dieses Beitrags ist es, darzustellen, was auslösende Momente für wissenschaftliche Karrieren sind, die in Professuren pflegebezogener Studiengänge münden, und welche Kontextbedingungen diese Karrieren beeinflussen. Es soll auch aufgezeigt werden, wie wissenschaftliche Nachwuchskräfte vorgehen, um ihre Ziele zu erreichen und welche Konsequenzen sich daraus für sie und für die Pflegewissenschaft ergeben. Auf dieser Grundlage sollen Empfehlungen für die Nachwuchsförderung entwickelt werden, um mehr geeignete Personen für Professuren in pflegebezogenen Studiengängen zu gewinnen. Vorhandene Daten teilnarrativer Interviews mit ProfessorInnen (n=11) und Masterstudierenden (n=11) sowie Promovierenden (n=10) pflegebezogener Studiengänge wurden im Rahmen einer retrospektiven Datenanalyse mit dem dreistufigen Codierverfahren der Grounded Theory Methodologie ausgewertet. Die Ergebnisse zeigen, dass in der Pflegepraxis gewonnene Erfahrungen auslösende Momente wissenschaftlicher Karrieren sind. Diese lösen den Drang aus, die dort herrschende Situation zu verändern, wobei sich vier Karrieretypen unterscheiden lassen: Typ A forscht, weil er erlebt hat, dass es für pflegerische Phänomene keine geeigneten Pflegeinterventionen gab. Typ B lehrt, um dazu beizutragen, dass Pflegende zukünftig besser ausgebildet werden. Typ C ist als Pflegeperson von ÄrztInnen nicht ausreichend anerkannt worden und absolviert eine wissenschaftliche Qualifikation, um mit ihnen auf Augenhöhe zu gelangen. Typ D wollte in der Praxis bleiben, ist aber bei Weiterentwicklungsprozessen blockiert worden und nimmt als Kompromiss eine Professur an. Identifizierte Kontextfaktoren sind u.a. mangelnde Wertschätzung für wissenschaftliches Handeln in der Pflege und das Fehlen von Stellen für hochschulisch qualifizierte Pflegepersonen in der Praxis. Angesichts der bestehenden Bedingungen können hochschulisch qualifizierte Pflegende in der Praxis nicht Fuß fassen. Als Konsequenz für die Pflegewissenschaft als Disziplin zeigt sich, dass in der Pflegepraxis Vorbilder fehlen, die zukünftige Generationen Pflegender dazu anregen könnten, selbst eine wissenschaftliche Karriere in der Pflege einzuschlagen. Dadurch besteht die Gefahr einer Verkümmerung der Pflegewissenschaft. Auf Grundlage der Ergebnisse wird die durchgängige Implementierung geeigneter Stellen für hochschulisch qualifizierte Pflegepersonen in der Pflegepraxis als Ausgangsbasis wissenschaftlicher Nachwuchsförderung betrachtet. Als Konzept werden Hochschul-Praxis-Partnerschaften skizziert, die beginnend auf Bachelorniveau bis zur Post-doc-Phase Strukturen zu einem systematischen praxisbezogenen wissenschaftlichen Kompetenzauf- und -ausbau für akademisch qualifizierte Pflegende etablieren.

Admission related processes are lacking adequate participation of older people and their families. To improve transitions to nursing homes, context- and country-specific knowledge about the current practice is needed. Hence, our aim was to summarize available evidence on challenges and care strategies associated with the admission to nursing homes in Germany. Methods We conducted a scoping review and searched eight major international and German-specific electronic databases for journal articles and grey literature published in German or English language since 1995. Further inclusion criteria were focus on challenges or care strategies in the context of nursing home admissions of older persons and comprehensive and replicable information on methods and results. Posters, only-abstract publications and articles dealing with mixed populations including younger adults were excluded. Challenges and care strategies were identified and analysed by structured content analysis using the TRANSCIT model. Results Twelve studies of 1,384 records were finally included. Among those, seven were qualitative studies, three quantitative observational studies and two mixed methods studies. As major challenges neglected participation of older people, psychosocial burden among family caregivers, inadequate professional cooperation and a lack of shared decision-making and evidence-based practice were identified. Identified care strategies included strengthening shared decision-making and evidence-based practice, improvement in professional cooperation, introduction of specialized transitional care staff and enabling participation for older people. Conclusion Although the process of nursing home admission is considered challenging and tends to neglect the needs of older people, little research is available for the German health care system. The perspective of the older people seems to be underrepresented, as most of the studies focused on caregivers and health professionals. Reported care strategies addressed important challenges, however, these were not developed and evaluated in a comprehensive and systematic way. Future research is needed to examine perspectives of all the involved groups to gain a comprehensive picture of the needs and challenges. Interventions based on existing care strategies should be systematically developed and evaluated to provide the basis of adequate support for older persons and their informal caregivers.

In dieser Studie wurden die Einflüsse durch die Schmelzeaufbereitung eines cellulosefaserverstärkten Polypropylens auf die Faser und den Faserverbund untersucht. Die Schmelze wurde in einem Plastographen mit verschiedenen Rotordrehzahlen, Schmelzetemperaturen und Verweilzeiten aufbereitet. Um die Auswirkung der Einspeisungsmethode auf den Faserabbau zu analysieren, wurden die Fasern entweder direkt der thermoplastischen Schmelze oder zusammen mit dem Kunststoffgranulat dem Plastographen zugeführt. Die Zugabe der Fasern in die Schmelze geht mit einer erhöhten thermischen und verminderten mechanischen Belastung der Fasern einher. Bei der Prüfung der mechanischen Eigenschaften der verschieden aufbereiteten Compounds zeigten sich signifikante Unterschiede. Wurden die Fasern direkt der Schmelze hinzugefügt, so führte dies zu einer deutlich reduzierten Zugfestigkeit. Optische Unterschiede in den Schliffbildern der spritzgegossenen Prüfstäbe sowie in den Faserlängen nach Compoundierung konnten nicht festgestellt werden. Die verminderte Festigkeit wird folglich auf die unterschiedliche thermische Belastung der Faser während der Verarbeitung zurückgeführt.

Im deutschsprachigen Raum (DACH-Raum) sind mehrere Förderprogramme zur Entwicklung und Evaluation von DiAP mit öffentlichen Mitteln etabliert worden. Ziel dieser Studie ist es, eine Übersicht über Evaluationsmethoden zu gewinnen, die in diesen geförderten Projekten angewendet werden. Es wurde eine multizentrische Querschnittstudie mit schriftlicher und telefonischer Befragung evaluationsverantwortlicher Wissenschaftler_innen durchgeführt. Die Identifikation relevanter Projekte erfolgte über die Suche in zehn Förderdatenbanken. Die Daten wurden mittels deskriptiver Statistik sowie deskriptiver strukturierender Inhaltsanalyse mit deduktiv-induktiver Kategorienbildung analysiert. Von 124 identifizierten Projekten nahmen 47 an der Studie teil. Alle Projekte sind multidisziplinär, am häufigsten vertreten sind Pflege(-wissenschaft) und MINT-Disziplinen. Akzeptanz und Machbarkeit sind vorrangige Evaluationsziele, als methodologisches Rahmenmodell wurde am häufigsten User-centered design genannt.

N2 - Hubs are at the core of most smart homes. Modern cross-ecosystem protocols and standards enable smart home hubs to achieve interoperability across devices, offering the unique opportunity to integrate universally available smart home privacy awareness and control features. To date, such privacy features mainly focus on individual products or prototypical research artifacts. We developed a cross-ecosystem hub featuring a tangible dashboard and a digital web application to deepen our understanding of how smart home users interact with functional privacy features. The ecosystem allows users to control the connectivity states of their devices and raises awareness by visualizing device positions, states, and data flows. We deployed the ecosystem in six households for one week and found that it increased participants’ perceived control, awareness, and understanding of smart home privacy. We further found distinct differences between tangible and digital mechanisms. Our findings highlight the value of cross-ecosystem hubs for effective privacy management.

To design an optimal implementation strategy, potential barriers to and facilitators of implementation must be considered. The objective of this systematic review is to identify barriers to and facilitators of the implementation of CPWs in primary care (PC). Methods: A systematic search via Cochrane Library, CINAHL, and MEDLINE via PubMed supplemented by hand searches and citation tracing was carried out. We considered articles reporting on CPWs targeting patients at least 65 years of age in outpatient settings that were written in the English or German language and were published between 2007 and 2019. We considered (non-)randomized controlled trials, controlled before-after studies, interrupted time series studies (main project reports) as well as associated process evaluation reports of either methodology. Two independent researchers performed the study selection; the data extraction and critical appraisal were duplicated until the point of perfect agreement between the two reviewers. Due to the heterogeneity of the included studies, a narrative synthesis was performed. Results: Fourteen studies (seven main project reports and seven process evaluation reports) of the identified 8154 records in the search update were included in the synthesis. The structure and content of the interventions as well as the quality of evidence of the studies varied. The identified barriers and facilitators were classified using the Context and Implementation of Complex Interventions framework. The identified barriers were inadequate staffing, insufficient education, lack of financial compensation, low motivation and lack of time. Adequate skills and knowledge through training activities for health professionals, good multi-disciplinary communication and individual tailored interventions were identified as facilitators. Conclusions: In the implementation of CPWs in PC, a multitude of barriers and facilitators must be considered, and most of them can be modified through the careful design of intervention and implementation strategies. Furthermore, process evaluations must become a standard component of implementing CPWs to enable other projects to build upon previous experience.

Virtual reality (VR) is an innovative approach to engage and motivate patients during training. There is promising evidence for its efficiency in retraining upper limb function. However, there is insufficient proof for its effectiveness in gait training. AIM: To evaluate the acceptability of robot-assisted gait training (RAGT) with and without VR and the feasibility of potential outcome measures to guide the planning of a larger randomized controlled trial (RCT). DESIGN: Single-blind randomized controlled pilot trial with two parallel arms. SETTING: Rehabilitation hospital. POPULATION: Twenty subacute stroke patients (64±9 years) with a Functional Ambulation Classification (FAC) ≤2. METHODS: Twelve sessions (over 4 weeks) of either VR-augmented RAGT (intervention group) or standard RAGT (control group). Acceptability of the interventions (drop-out rate, questionnaire), patients’ motivation (Intrinsic Motivation Inventory [IMI], individual mean walking time), and feasibility of potential outcome measures (completion rate and response to interventions) were determined. RESULTS: We found high acceptability of repetitive VR-augmented RAGT. The drop-out rate was 1/11 in the intervention and 4/14 in the control group. Patients of the intervention group spent significantly more time walking in the robot than the control group (per session and total walking time; P<0.03). In both groups, motivation measured with the IMI was high over the entire intervention period. The felt pressure and tension significantly decreased in the intervention group (P<0.01) and was significantly lower than in the control group at the last therapy session (r=-0.66, P=0.005). The FAC is suggested as a potential primary outcome measure for a definitive RCT, as it could be assessed in all patients and showed significant response to interventions (P<0.01). We estimated a sample size of 44 for a future RCT. CONCLUSIONS: VR-augmented RAGT resulted in high acceptability and motivation, and in a reduced drop-out rate and an extended training time compared to standard RAGT. This pilot trial provides guidance for a prospective RCT on the effectiveness of VR-augmented RAGT. CLINICAL REHABILITATION IMPACT: VR might be a promising approach to enrich and improve gait rehabilitation after stroke.

Physiotherapie kann einen positiven Einfluss auf das Gleichgewicht und Sturzrisiko bei Patient*innen mit S/G haben. In der S3-DEGAM-Leitlinie „Akuter Schwindel in der Hausarztpraxis“ werden Empfehlungen für Physiotherapie bei bestimmten Schwindeldiagnosen gegeben. Ob hausärztliche Physiotherapieverordnungen den Empfehlungen der Leitlinie entsprechen, ist nicht bekannt. Bisher liegen keine Daten vor, wie häufig diese Physiotherapieverordnungen tatsächlich durch Patient*innen in Anspruch genommen werden. Ziel Ermittlung von Anteil und Inanspruchnahme hausärztlich verordneter Physiotherapie bei älteren Patient*innen mit S/G innerhalb der Kohortenstudie MobilE-TRA und Untersuchung, ob diese den Empfehlungen der S3-DEGAM-Leitlinie entsprechen. Methode Die Sekundäranalyse beruht auf Daten der Kohortenstudie MobilE-TRA, in der Patient*innen ab 65 Jahren mit S/G in 17 Hausarztpraxen in Bayern und Sachsen befragt wurden. Die Datenerhebung fand von 09/2017–10/2019 statt. Die hausärztliche Verordnung und patientenseitige Inanspruchnahme von Physiotherapie wurden mittels validierten sowie selbstentwickelten Fragebögen erhoben. Die Daten wurden deskriptiv (Mittelwerte, Häufigkeiten) und Verteilungsunterschiede mittels exaktem Test nach Fisher analysiert. Ergebnisse Die Stichprobe umfasste 158 Patient*innen mit S/G. 16 % der Patient*innen hatten aufgrund von S/G Physiotherapie verordnet bekommen. Dabei entsprachen 14,2 % der Physiotherapieverordnungen den Empfehlungen der S3-DEGAM-Leitlinie. 32 % (Bayern 53,8 %; Sachsen 8,3 %) der Patient*innen hatten die Physiotherapie nicht in Anspruch genommen. Dabei lag ein signifikanter regionaler Verteilungsunterschied (p = 0,030; Phi = 0,487 [95 % KI = 0,129–0,846]) vor. Schlussfolgerung Mit 16 % ist die Häufigkeit hausärztlicher Physiotherapieverordnungen bei S/G in der Altersgruppe der über 65-Jährigen vergleichsweise hoch. Die Gründe für die Nichtinanspruchnahme wurden nicht erfasst, weshalb nur Vermutungen bezüglich des regionalen Unterschiedes angestellt werden konnten (z. B. Verfügbarkeit von Physiotherapie). Im Sinne der Planung einer adhärenten Therapie und zur Vermeidung von Versorgungsunterschieden scheint es sinnvoll, sich zukünftig auch mit Gründen einer Nichtinanspruchnahme von Therapien zu beschäftigen.

The aim of this study was to identify the quality of evidence of physical therapy interventions that address mobility and participation in older patients with VDB and to characterize the used primary and secondary outcomes. Methods A systematic search via MEDLINE (PubMed), Cochrane Library, CINAHL, PEDro, forward citation tracing and hand search was conducted initially in 11/2017 and updated in 7/2019. We included individual and cluster-randomized controlled trials and trials with quasi-experimental design, published between 2007 and 2017/2019 and including individuals ≥65 years with VDB. Physical therapy and related interventions were reviewed with no restrictions to outcome measurement. Screening of titles, abstracts and full texts, data extraction and critical appraisal was conducted by two independent researchers. The included studies were heterogeneous in terms of interventions and outcome measures. Therefore, a narrative synthesis was conducted. Results A total of 20 randomized and 2 non-randomized controlled trials with 1876 patients met the inclusion criteria. The included studies were heterogeneous in terms of complexity of interventions, outcome measures and methodological quality. Vestibular rehabilitation (VR) was examined in twelve studies, computer-assisted VR (CAVR) in five, Tai Chi as VR (TCVR) in three, canal repositioning manoeuvres (CRM) in one and manual therapy (MT) in one study. Mixed effects were found regarding body structure/function and activities/participation. Quality of life and/or falls were assessed, with no differences between groups. VR is with moderate quality of evidence superior to usual care to improve balance, mobility and symptoms. Conclusion To treat older individuals with VDB, VR in any variation and in addition to CRMs seems to be effective. High-quality randomized trials need to be conducted to inform clinical decision making. Trial registration PROSPERO 2017 CRD42017080291.

We previously developed a care pathway (CPW) to improve their mobility and participation by offering standardized approaches for general practitioners (GPs) and physical therapists (PTs). We aimed to assess the feasibility of the intervention, its implementation strategy and the study procedures in preparation for the subsequent main trial. Methods This 12-week prospective cohort feasibility study was accompanied by a process evaluation designed according to the UK Medical Research Council’s Guidance for developing and evaluating complex interventions. Patients with VDB (≥65 years), GPs and PTs in primary care were included. The intervention consisted of a diagnostic screening checklist for GPs and a guide for PTs. The implementation strategy included specific educational trainings and a telephone helpline. Data for mixed-method process evaluation were collected via standardized questionnaires, field notes and qualitative interviews. Quantitative data were analysed using descriptive statistics, qualitative data using content analysis. Results A total of five GP practices (seven single GPs), 10 PT practices and 22 patients were included in the study. The recruitment of GPs and patients was challenging (response rates: GP practices: 28%, PT practices: 39%). Ninety-one percent of the patients and all health professionals completed the study. The health professionals responded well to the educational trainings; the utilization of the telephone helpline was low (one call each from GPs and PTs). Familiarisation with the routine of application of the intervention and positive attitudes were emphasized as facilitators of the implementation of the intervention, whereas a lack of time was mentioned as a barrier. Despite difficulties in the GPs’ adherence to the intervention protocol, the GPs, PTs and patients saw benefit in the intervention. The patients’ treatment adherence to physical therapy was good. There were minor issues in data collection, but no unintended consequences. Conclusion Although the process evaluation provided good support for the feasibility of study procedures, the intervention and its implementation strategy, we identified a need for improvement in recruitment of participants, the GP intervention part and the data collection procedures. The findings will inform the main trial to test the interventions effectiveness in a cluster RCT.

An evidence-based, multidisciplinary care pathway (CPW) in primary care was developed and pilot tested in a previous study. The aim of the present study is to evaluate the effectiveness and safety of the CPW in terms of improving mobility and participation in community-dwelling older people with VDB in primary care. Methods For this multicentre cluster randomised controlled clinic trial, general practitioners (GP) will be recruited in two regions of Germany. A total of 120 patients over 60 years old with VDB will be included. The intervention is an algorithmized CPW. GPs receive a checklist for standardise clinical decision making regarding diagnostic screening and treatment of VDB. Physiotherapists (PT) receive a decision tree for evidence-based physiotherapeutic clinical reasoning and treatment of VDB. Implementation strategies comprises educational trainings as well as a workshop to give a platform for exchange for the GPs and PTs, an information meeting and a pocket card for home care nurses and informal caregivers and telephone peer counselling to give all participants the capability, opportunity and the motivation to apply the intervention. In order to ensure an optimised usual care in the control group, GPs get an information meeting addressing the national guideline. The primary outcome is the impact of VDB on participation and mobility of patients after 6 month follow-up, assessed using the Dizziness Handicap Inventory (DHI) questionnaire. Secondary outcomes are physical activity, static and dynamic balance, falls and fear of falling as well as quality of life. We will also evaluate safety and health economic aspects of the intervention. Behavioural changes of the participants as well as barriers, facilitating factors and mechanisms of impact of the implementation will be investigated with a comprehensive process evaluation in a mixed-methods design. Discussion With our results, we aim to improve evidence-based health care of community-dwelling older people with VDB in primary care.

Due to a multifactorial aetiology, health care is often overutilised, but many patients are also treated insufficiently in primary care. The purpose of this study was to develop a care pathway as a complex intervention to improve mobility and participation in older people with VDB in primary care. Methods The development process followed the UK Medical Research Council guidance using a mixed-methods design with individual and group interviews carried out with patients, physical therapists (PTs), general practitioners (GPs), nurses working in community care and a multi-professional expert panel to create a first draft of a care pathway (CPW) and implementation strategy using the Consolidated Framework of Implementation Research and the Expert recommendations for Implementing Change. Subsequently, small expert group modelling of specific components of the CPW was carried out, with GPs, medical specialists and PTs. The Behaviour Change Wheel was applied to design the intervention´s approach to behaviour change. To derive theoretical assumptions, we adopted Kellogg´s Logic Model to consolidate the hypothesized chain of causes leading to patient-relevant outcomes. Results Individual interviews with patients showed that VDB symptoms need to be taken more seriously by GPs. Patients demanded age-specific treatment offers, group sessions or a continuous mentoring by a PT. GPs required a specific guideline for diagnostics and treatment options including psychosocial interventions. Specific assignment to and a standardized approach during physical therapy were desired by PTs. Nurses favoured a multi-professional documentation system. The structured three-day expert workshop resulted in a first draft of CPW and potential implementation strategies. Subsequent modelling resulted in a CPW with components and appropriate training materials for involved health professionals. A specific implementation strategy is now available. Conclusion A mixed-methods design was suggested to be a suitable approach to develop a complex intervention and its implementation strategy. We will subsequently test the intervention for its acceptability and feasibility in a feasibility study accompanied by a comprehensive process evaluation to inform a subsequent effectiveness trial.

The Consolidated Framework for Implementation Research (CFIR) facilitates identification of contextual barriers and facilitators, and the Expert Recommendations for Implementing Change (ERIC) allows identifying adequate implementation strategies. Both instruments are already used in German-speaking countries; however, no standardised and validated translation is available thus far. The aim of this study was to translate the CFIR and ERIC framework into German, in order to increase the use of these frameworks and the adherence to evidence-based implementation efforts in German-speaking countries. Methods The translation of the original versions of the CFIR and ERIC framework was guided by the World Health Organisation’s recommendations for the process of translating and adapting both conceptual frameworks. Accordingly, a four-step process was employed: first, forward translation from English into German was conducted by a research team of German native speakers with fluent knowledge of the English language. Second, a bilingual expert panel comprising one researcher with German as his mother tongue and expert command of the English language and one English language expert and university teacher reviewed the translation and discussed inconsistencies with the initial translators. Third, back-translation into English was conducted by an English native speaking researcher. The final version was pre-tested with 12 German researchers and clinicians who were involved in implementation projects using cognitive interviews. Results The translation and review process revealed some inconsistencies between the original version and the German translations. All issues could be solved by discussion. Central aspects of the items were confirmed in 60 to 70% of the items, and modifications were proposed in 30% of the items. Finally, we revised one CFIR-item heading after pre-testing. The final version was given consent by all involved parties. Conclusions Now, two validated and tested implementation frameworks to guide implementation efforts are available in the German language and can be used to increase the application of agreed-on implementation strategies into practice.
