T1 - Systematic Review and Meta-analysis of the Effectiveness of Implementation Strategies for Non-communicable Disease Guidelines in Primary Health Care JF - Journal of General Internal Medicine N2 - Background As clinical practice guidelines represent the most important evidence-based decision support tool, several strategies have been applied to improve their implementation into the primary health care system. 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.

A1 - Gibbs, Barry T1 - Approximate method for obtaining source quantities for calculation of structure-borne sound transmission into lightweight buildings JF - Applied Acoustics N2 - An approximate approach is described, for obtaining the source quantities required for the calculation of structure-borne sound power from machines into supporting lightweight building elements. The approach is in two stages, which are based on existing international Standards for measurement. The first stage involves direct measurement of the source free velocity at each contact, to give the sum of the square velocities. The second stage is based on the reception plate method and yields the single equivalent blocked force, which approximates the sum of the square blocked forces. The applicability of the source data obtained has been investigated in a case study of a fan unit on a timber joist floor. The approach contains several significant simplifying assumptions and the uncertainties associated with them are considered. For the case considered, the power transmitted into the floor is estimated by the approximate method to within 5 dB of the true value, on average.

T2 - 6th International Conference on Smart Cities and Green ICT Systems (SMARTGREENS) N2 - Shifting energy peak load is a subject that plays a huge role in the currently changing energy market, where renewable energy sources no longer produce the exact amount of energy demanded. Matching demand to supply requires behavior Changes on the customerside, which can be achieved by incentives suchas Real-Time-Pricing (RTP). Various studies show that such incentives cannot be utilized without a complexity reduction, e.g., by smart home automation systems that inform the customer about possible savings or automatically schedule appliances to off-peak load phases. We propose a probabilistic appliance usage prediction based on historical energy data that can be used to identify the times of day where an appliance will be used and therefore make load shift recommendations that suite the customer’s usage profile. A huge issue is how to provide a valid performance evaluation for this particular problem. We will argue why the commonly used accuracy metric is not suitable, and suggest to use other metrics like the area under the Receiver Operating Characteristic (ROC) curve, Matthews Correlation Coefficient (MCC) or F1-Score instead.

Design: Multi-centre cohort study. Patients: A total of 391 patients (50.1% female, mean age 63.4 years) from 4 university hospitals in Austria, Germany and Switzerland and one Austrian general hospital. Methods: Data on functioning were collected using the respective comprehensive acute ICF Core Sets. Data were extracted from patients' medical record sheets and interviews with health professionals and patients. Results: Most of the categories of the comprehensive ICF Core Sets describing impairments, limitations or restrictions occurred in a considerable proportion of the study population. The most outstanding limitations and restrictions of the patients were problems with sleep and blood vessel functions, walking and moving and self-care. Thirty-eight aspects of functioning not previously covered by the comprehensive ICF Core Sets were ranked as relevant. Conclusion: Categories of the comprehensive ICF Core Sets for the acute hospital situation were confirmed. Some additional categories not covered by the Set in its present version emerged from the interviews, and should be considered for inclusion in a finalized version.

T1 - Vibroacoustic finite element modelling of the low-frequency performance of a solid timber floor formed from dowel-connected joists JF - Proceedings of Inter-Noise 2016 N2 - This paper investigates the prediction of low-frequency impact sound insulation for a solid timber floor formed from dowel-connected joists with Swiss hardwood. A finite element model was developed for the dynamic response of the floor as it is neither homogeneous nor isotropic and has complex connections. With point force excitation, a FEM model for the dynamic response of the floor was validated using experimental modal analysis in the laboratory. Two different FEM models were developed, one using spring connectors and the other using join connectors. Good agreement between FEM and measurements in terms of the Modal Assurance Criterion (MAC) and eigenfrequencies was achieved for the first 14 modes with the spring connector model and for the first 7 modes with the join connector model. However, for the vibroacoustic analysis it was necessary to use the join connector model due to the computational instabilities of the spring model above 100 Hz when it was coupled to the acoustic medium. With mechanical excitation the radiated sound power from the underside of the timber floor was measured with sound intensity in order to calculate the radiation efficiency. Comparison of measurements and FEM showed reasonable agreement between 20Hz and 200Hz KW - Schallmesstechnik KW - Holzbau Y1 - 2016 ER - TY - JOUR A1 - Haderlein, Tino A1 - Riedhammer, Korbinian A1 - Nöth, Elmar A1 - Toy, Hikmet A1 - Schuster, Maria A1 - Eysholdt, Ulrich A1 - Hornegger, Joachim A1 - Rosanowski, Frank T1 - Application of Automatic Speech Recognition to Quantitative Assessment of Tracheoesophageal Speech in Different Signal Quality JF - Folia Phoniatrica Et Logopaedica N2 - Tracheoesophageal voice is state-of-the-art in voice rehabilitation after laryngectomy. Intelligibility on a telephone is an important evaluation criterion as it is a crucial part of social life. An objective measure of intelligibility when talking on a telephone is desirable in the field of postlaryngectomy speech therapy and its evaluation. Based upon successful earlier studies with broadband speech, an automatic speech recognition (ASR) system was applied to 41 recordings of postlaryngectomy patients. Recordings were available in different signal qualities; quality was the crucial criterion for this study. Compared to the intelligibility rating of 5 human experts, the ASR system had a correlation coefficient of r = -0.87 and Krippendorff's alpha of 0.65 when broadband speech was processed. The rater group alone achieved alpha = 0.66. With the test recordings in telephone quality, the system reached r = -0.79 and alpha = 0.67. For medical purposes, a comprehensive diagnostic approach to (substitute) voice has to cover both subjective and objective tests. An automatic recognition system such as the one proposed in this study can be used for objective intelligibility rating with results comparable to those of human experts. This holds for broadband speech as well as for automatic evaluation via telephone. KW - Speech Recognition Software Y1 - 2008 VL - 2008 IS - 61(1) SP - 12 EP - 17 ER - TY - JOUR A1 - Grill, E.

ED - Medical Journals Limited, T1 - Brief ICF Core Sets for the acute hospital JF - Journal of Rehabilitation Medicine N2 - Objective: To identify candidate categories for brief International Classification of Functioning, Disability and Health (ICF) Core Sets for the reporting and measurement of functioning in patients in the acute hospital. 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. Conclusion: The present selection of categories can be considered an initial proposal, serving to identify the ICF categories most relevant for the practical assessment and monitoring of functioning in patients with acute neurological, cardiopulmonary, and musculoskeletal conditions.

A standardized questionnaire was completed by 2023 parents in Germany with children with diarrhea who were younger than 2 years old. Parents stated the most worrying aspects of diarrhea. A health score was measured using a visual analogue scale (0 = worst health, 100 = best health). Clinical symptoms were quoted by 72% of parents as one of the most worrying dimensions, with duration/frequency of diarrhea and weight loss perceived most meaningful. Next were behavioral/physical symptoms (51%), with an inflamed bottom for mild disease and pain for severe cases being most meaningful. Parental concern is characterized by sympathy and anxiety for the child. The health score for the diarrheal episode was 54.6 for mild and 33.9 for severe cases. Parents perceive a high disease burden of diarrhea and clinically less meaningful aspects play a significant role.

(2017) European initiative for the application of the International Classification of Functioning, Disability and Health: Development of Clinical Assessment Schedules for specified rehabilitation services JF - European Journal of physical and rehabilitation medicine N2 - Clinical assessment schedule (CLAS) is a core part of the ICF-based implementation of functioning reporting across health conditions and along the continuum of care. The Physical and Rehabilitation Medicine Section and Board of the European Union of Medical Specialists (UEMS PRM) workshop held in January 2016 aimed to develop and specify a CLAS within the context of rehabilitation services. UEMS PRM Workshop in Nottwil, Switzerland, January 2016.PRM physicians representatives from 12 European countries, as well as Israel and Japan, mostly delegates of UEMS PRM Section and Board, and experts with other rehabilitation professional backgrounds.Participants were divided into 6 working groups and asked to specify what functioning aspects would be essential to document using the available ICF sets for the identified rehabilitation services contained in the newly developed service classification (ICSO-R): acute, post-acute and long-term rehabilitation services. The 7 ICF Generic and 23 Rehabilitation Set categories were confirmed as well as specific health condition categories for acute rehabilitation services (mobile team), for postacute rehabilitation services (general outpatient rehabilitation, musculoskeletal and neurological rehabilitation, as well as specialized SCI rehabilitation), and for long-term rehabilitation services (day clinic and rehabilitation provided in the community). While general principles of the CLAS were defined, the need to align the CLAS for a specific service, as well as across services along the continuum of care was highlighted. All groups deliberated on this topic; however, no conclusive statement was presented yet.The groups recognized a need for a systematic effort to identify data collection tools currently used.CLASs will serve in the future to ensure that functioning information is systematically and consistently collected across services, and thus respond also to various global reports and initiatives which stress the need for improving data collection on people's functioning.

The challenge in the orbit prediction is that the real electrical propulsion thrust is known with limited accuracy only. In combination with thrust pointing errors, these inaccuracies can accumulate to large orbit position errors during long low thrust burn arcs. The discrepancy between real and predicted satellite position is determined in terms of probability and as a worst case scenario.

T1 - Measuring Functioning in People with Fibromyalgia (FM) Based on the International Classification of Functioning, Disability and Health (ICF)—A Psychometric Analysis JF - Pain Practice N2 - Objectives: Instruments to assess functioning in patients with FM vary considerably in their content and are often symptom‐specific. This study aimed to examine whether it is feasible to construct a psychometric‐sound clinical instrument to measure functioning in FM based on the Brief ICF‐Core‐Set for chronic widespread pain (CWP). Methods: Two hundred and fifty six people with FM completed the Brief ICF‐Core‐Set. The Rasch model was used for analysis. Once ordering of response options of ICF categories was ensured, the following properties were studied: fit of the ICF categories to the Rasch model, the targeting between ICF categories and a person’s abilities, unidimensionality, and reliability. Results: Six ICF categories were rescored due to disordered thresholds. Five ICF categories were removed due to high model‐misfit and differential item functioning (DIF) for gender. Scores from 46 participants were excluded due to extreme scores. The ICF categories included display consistency with an underlying unidimensional construct, are free of DIF for age, disease duration and gender, display excellent overall reliability, and cover a range of functioning difficulties. Conclusions: This study illustrates that it is possible to measure functioning as a unidimensional construct based on selected ICF categories from the components body functions, as well as activities and participation of the Brief ICF‐Core‐Set for CWP in patients with FM.

T1 - Compiling standardized information from clinical practice: using content analysis and ICF Linking Rules in a goal-oriented youth rehabilitation program JF - Disability and Rehabilitation N2 - Purpose: To illustrate how routinely written narrative admission and discharge reports of a rehabilitation program for eight youths with chronic neurological health conditions can be transformed to the International Classification of Functioning, Disability and Health. Methods: First, a qualitative content analysis was conducted by building meaningful units with text segments assigned of the reports to the five elements of the Rehab-Cycle®: goal; assessment; assignment; intervention; evaluation. Second, the meaningful units were then linked to the ICF using the refined ICF Linking Rules. Results: With the first step of transformation, the emphasis of the narrative reports changed to a process oriented interdisciplinary layout, revealing three thematic blocks of goals: mobility, self-care, mental, and social functions. The linked 95 unique ICF codes could be grouped in clinically meaningful goal-centered ICF codes. Between the two independent linkers, the agreement rate was improved after complementing the rules with additional agreements. Conclusions: The ICF Linking Rules can be used to compile standardized health information from narrative reports if prior structured. The process requires time and expertise. To implement the ICF into common practice, the findings provide the starting point for reporting rehabilitation that builds upon existing practice and adheres to international standards. Implications for Rehabilitation This study provides evidence that routinely collected health information from rehabilitation practice can be transformed to the International Classification of Functioning, Disability and Health by using the “ICF Linking Rules”, however, this requires time and expertise. The Rehab-Cycle®, including assessments, assignments, goal setting, interventions and goal evaluation, serves as feasible framework for structuring this rehabilitation program and ensures that the complexity of local practice is appropriately reflected. The refined “ICF Linking Rules” lead to a standardized transformation process of narrative text and thus a higher quality with increased transparency. As a next step, the resulting format of goal codes supplemented by goal-clarifying codes could be validated to strengthen the implementation of the International Classification of Functioning, Disability and Health into rehabilitation routine by respecting the variety of clinical practice.

T1 - MOBSY: Integration of vision and dialogue in service robots T2 - Computer Vision Systems, Proceedings Second International Workshop, ICVS 2001, Vancouver, Canada N2 - MOBSY is a fully integrated autonomous mobile service robot system. It acts as an automatic dialogue based receptionist for visitors of our institute. MOBSY incorporates many techniques from different research areas into one working stand-alone system. Especially the computer vision and dialogue aspects are of main interest from the pattern recognition’s point of view. To summarize shortly, the involved techniques range from object classification over visual self-localization and recalibration to object tracking with multiple cameras. A dialogue component has to deal with speech recognition, understanding and answer generation. Further techniques needed are navigation, obstacle avoidance, and mechanisms to provide fault tolerant behavior. This contribution introduces our mobile system MOBSY. Among the main aspects vision and speech, we focus also on the integration aspect, both on the methodological and on the technical level. We describe the task and the involved techniques. Finally, we discuss the experiences that we gained with MOBSY during a live performance at the 25th anniversary of our institute KW - Speech recognition KW - Obstacle Avoidance  KW - Humanoid Robot  KW - Service Robot Y1 - 2001 ER -
