There is very limited evidence on measures for prevention and treatment of disability due to joint contractures. We have developed the PECAN intervention (Participation Enabling CAre in Nursing) to improve social participation in nursing home residents. A cluster-randomised pilot trial was conducted to assess the feasibility of study procedures in preparation for a main trial according to the UK Medical Research Council (MRC) framework. Methods: Nursing homes in two regions of Germany were randomly allocated either to the intervention or optimised standard care (control group). All residents with joint contractures aged > 65 years were eligible for the study. The residents' data were collected through structured face-to-face interviews by blinded assessors at baseline, after 3 and 6 months. The primary outcome was social participation, measured by a subscale of the PaArticular Scales. Secondary outcomes included activities and instrumental activities of daily living, health-related quality of life, falls and fall-related consequences. Data on the trial feasibility were collected via documentation forms. Results: Seven out of 12 nursing homes agreed to participate and remained in the trial. Of 265 residents who fulfilled the inclusion criteria, 129 were randomised either to the intervention (n = 64) or control group (n = 65) and analysed. A total of 109 (85\%) completed the trial after 6 months. The mean age was 85.7 years (SD 7.0), 80\% were women. The severity of the residents' disability differed across the clusters. The completion rate was high (> 95\%), apart from the Instrumental Activities of Daily Living Scale. Some items of the PaArticular Scales were not easily understood by residents. The frequency of falls did not differ between study groups. Conclusion: Our data confirmed the feasibility of the overall study design.

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.

The purpose of this study was to develop a complex intervention to improve participation in nursing home residents with joint contractures. Methods The development followed the UK Medical Research Council framework using a mixed-methods design with re-analysis of existing interview data using a graphic modelling approach, group discussions with nursing home residents, systematic review of intervention studies, structured 2-day workshop with experts in geriatric, nursing, and rehabilitation, and group discussion with professionals in nursing homes. Results Graphic modelling identified restrictions in the use of transportation, walking within buildings, memory functions, and using the hands and arms as the central target points for the intervention. Seven group discussions with 33 residents revealed various aspects related to functioning and disability according the International Classification of Functioning, Disability and Health domains body functions, body structures, activities and participation, environmental factors, and personal factors. The systematic review included 17 studies with 992 participants: 16 randomised controlled trials and one controlled trial. The findings could not demonstrate any evidence in favour of an intervention. The structured 2-day expert workshop resulted in a variety of potential intervention components and implementation strategies. The group discussion with the professionals in nursing homes verified the feasibility of the components and the overall concept. The resulting intervention, Participation Enabling CAre in Nursing (PECAN), will be implemented during a 1-day workshop for nurses, a mentoring approach, and supportive material. The intervention addresses nurses and other staff, residents, their informal caregivers, therapists, and general practitioners. Conclusions In view of the absence of any robust evidence, the decision to use mixed methods and to closely involve both health professionals and residents proved to be an appropriate means to develop a complex intervention to improve participation of and quality of life in nursing home residents. We will now evaluate the PECAN intervention for its impact and feasibility in a pilot study in preparation for an evaluation of its effectiveness in a definitive trial.

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.

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.

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.

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.

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.

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.}, language = {en} } @article{StroblMuellerThorandetal.2014, author = {Strobl, R. and M{\"u}ller, Martin and Thorand, B. and Linkohr, B. and Autenrieth, C.

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. In addition, men seem to benefit more from leisure-time physical activity than women}, language = {en} } @article{RoehrigStroblMuelleretal.2014, author = {Roehrig, N. and Strobl, R. and M{\"u}ller, Martin and Perz, S. and Kaab, S. and Martens, E. and Peters, A. and Linkohr, B. and Grill, E.}, title = {Directed acyclic graphs helped to identify confounding in the association of disability and electrocardiographic findings: results from the KORA-Age study}, series = {Journal of clinical epidemiology}, journal = {Journal of clinical epidemiology}, editor = {PlumX Metrics,}, year = {2014}, abstract = {Objectives To examine the association between electrocardiographic (ECG) findings and disability status in older adults. Study Design and Setting KORA-Age, a population-based cross-sectional study of the MONICA/KORA project, a randomized sample from Southern Germany of people aged 65 years or older. 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.

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.

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.

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. Strategies to systematically include the management and the nursing team from the beginning are needed to support the facilitators during implementation in the main trial.
