Predictors of Residential Care Admission in Community-Dwelling Older People With Dementia.

ABSTRACT:

Objectives

The objectives of this study were to identify variables associated with dementia and entry into aged residential care (ARC) and derive and validate a risk prediction model for dementia and entry into ARC.

Design

This was an observational study of prospectively collected Home Care International Residential Assessment Instrument (interRAI-HC) assessment data.

Setting and participants

Participants included all people age ≥65 years who had completed an interRAI-HC assessment between July 1, 2012 and June 30, 2018. Exclusion criteria included death or entry into ARC within 30 days of assessment and not living at home at the time of the assessment.

Measures

InterRAI data from 94,202 older New Zealanders were evaluated for presence or absence of dementia. A multivariable competing-risks model for entry into ARC with death as the competing event was used to estimate subdistribution hazard ratios (SHR).

Results

In total, there were 18,672 (19.8%) persons with dementia (PWD). PWD were almost twice as likely to enter ARC as persons without dementia [42.8% vs 25.3%; difference 17.5% (95% confidence interval 16.7%‒18.2%)]. PWD at highest risk of entering ARC were those where there was a desire to live elsewhere (SHR 1.44), depression (indicated, SHR 1.15), poor cognitive performance (Cognitive Performance Scale minimal SHR 1.32 and severe plus SHR 1.91), and wandering (SHR 1.19). Factors associated with reduced risks of PWD entering ARC were living with a child or relative, alcohol consumption, and comorbidities.

Conclusions and implications

A desire to live elsewhere, social isolation, independent activities of daily living, and depression were independently associated with entry into ARC. Supporting caregivers may improve outcomes for PWD that delay entry into ARC. Future revisions of the interRAI questionnaire could provide more insight on this matter.

Project description:BACKGROUND:Physical activity may decrease the risk of dementia; however, previous cohort studies seldom investigated the different types of physical activity and household activities. Our objective was to analyze the links between two physical activity types and dementia in older people. METHODS:The study used data from the prospective observational Three-city cohort and included 1550 community-dwelling individuals aged 72 to 87 without dementia at baseline. Physical activity was assessed with the Voorrips questionnaire. Two sub-scores were calculated to assess household/transportation activities and leisure/sport activities. Restricted cubic spline and proportional hazard Cox models were used to estimate the non-linear exposure-response curve for the dementia risk and the appropriate activity level thresholds. Models were adjusted for possible confounders, including socio-demographic variables, comorbidities, depressive symptoms and APOE genotype. RESULTS:The median age was 80 years, and 63.6% of participants were women. After a median follow-up of 4.6 years, dementia was diagnosed in 117 participants (7.6%). An inverse J-shaped association was found between household/transportation physical activity sub-score and dementia risk, which means that the risk is lowest for the moderately high values and then re-increases slightly for the highest values. The results remained significant when this sub-score was categorized in three classes (low, moderate, and high), with hazard ratios (95% confidence interval) of 0.55 (0.35-0.87) and 0.62 (0.38-1.01) for moderate and high activity levels, respectively. No significant effect was found for leisure/sport activities. CONCLUSIONS:The 5-year risk of dementia was significantly and negatively associated with the household/transportation activity level, but not with the leisure and sport activity sub-score. This highlights the importance of considering all physical activity types in 72 years or older people.

Project description:ObjectivesThe current practice of prescribing psychotropic medication for the management of dementia-related behavioral disturbances is under substantial debate. Using Pearlin's stress process model as theoretical underpinning, the aim of this investigation is to identify caregiver and care recipient characteristics as predictors of anxiolytic, antipsychotic, and antidepressant use among community-dwelling dementia patients. We hypothesized that caregiving burden and patient characteristics, particularly behavior disturbances and pain, would be positively associated with psychotropic medication use.MethodsData for this exploratory, cross-sectional study were drawn from the baseline assessment of the Resources for Enhancing Alzheimer's Caregiver Health II trial. Only participants with full baseline information were examined (N = 598). Caregiver characteristics, such as confidence managing problematic behaviors, and care recipient characteristics including pain, problem behaviors, cognitive impairment, and functional impairment, were examined in relation to care recipient psychotropic medication use.ResultsContrary to our hypothesis, behavioral disturbances and burden associated with these disturbances were not significantly associated with psychotropic use. Rather, caregiver characteristics such as race and overall vigilance, and care recipient characteristics such as cognitive status, functional status, and pain were significantly associated with the use of psychotropic medication. Findings differed by class of medication.ConclusionThese exploratory findings suggest the utility of a holistic approach to understanding the factors associated with pharmacotherapy among community-dwelling elders with dementia. Significant associations between caregiver characteristics and care recipient psychotropic medication use suggest that educating caregivers in non-pharmacologic strategies hold promise for a more balanced biopsychosocial approach to maintaining dementia patients in the community.

Project description:BackgroundThere is great need for development of feasible rehabilitation for older people with dementia. Increased understanding of this population's experiences of rehabilitation participation is therefore important. The aim of this study was to explore the experiences of community-dwelling older people with dementia participating in a person-centred multidimensional interdisciplinary rehabilitation program.MethodsSixteen older people with dementia were interviewed about their experiences of participation in a person-centred multidimensional interdisciplinary rehabilitation program. The program comprised assessments by a comprehensive team of rehabilitation professionals followed by a rehabilitation period of 16 weeks, including interventions based on individualized rehabilitation goals conducted with the support of the rehabilitation team. The rehabilitation was performed in the participants' homes, in the community and at an outpatient clinic, including exercise with social interaction in small groups offered twice a week to all participants. The interviews were conducted at the end of the rehabilitation period and analysed with qualitative content analysis.ResultsThe analysis resulted in one overarching theme: Empowered through participation and togetherness and four sub-themes: Being strengthened through challenges; Gaining insights, motives, and raising concerns about the future; Being seen makes participation worthwhile; and Feelings of togetherness in prosperity and adversity. The participants increased their self-esteem by daring and coping in the rehabilitation. The insights about themselves and their condition motivated them to continue with their prioritized activities, but also raised concerns about how the future would play out. Collaboration in the group and being seen and acknowledged by staff strengthened their own motivation and self-efficacy.ConclusionAccording to community-dwelling older people with dementia, a person-centred multidimensional interdisciplinary rehabilitation program was experienced as viable and beneficial. The participants seemed empowered through the rehabilitation and expressed mostly positive experiences and perceived improvements. Providers of interdisciplinary rehabilitation programs for this group should consider aspects raised by the participants e.g. the positive experience of being challenged in both exercise and daily activities; the importance of being seen and feeling secure; the benefits and challenges of collaboration with others in the same situation; and the generation of new perspectives of current and future situation.

Project description:Reablement is a rehabilitation intervention for community-dwelling older adults, which has recently been implemented in several countries. Its purpose is to improve functional ability in daily occupations (everyday activities) perceived as important by the older person. Performance and satisfaction with performance in everyday life are the major outcomes of reablement. However, the evidence base concerning which factors predict better outcomes and who receives the greatest benefit in reablement is lacking.The objective of this study was to determine the potential factors that predict occupational performance and satisfaction with that performance at 10 weeks follow-up.The sample in this study was derived from a nationwide clinical controlled trial evaluating the effects of reablement in Norway and consisted of 712 participants living in 34 municipalities. Multiple linear regression was used to investigate possible predictors of occupational performance (COPM-P) and satisfaction with that performance (COPM-S) at 10 weeks follow-up based on the Canadian Occupational Performance Measure (COPM).The results indicate that the factors that significantly predicted better COPM-P and COPM-S outcomes at 10 weeks follow-up were higher baseline scores of COPM-P and COPM-S respectively, female sex, having a fracture as the major health condition and high motivation for rehabilitation. Conversely, the factors that significantly predicted poorer COPM-P and COPM-S outcomes were having a neurological disease other than stroke, having dizziness/balance problems as the major health condition and having pain/discomfort. In addition, having anxiety/depression was a predictor of poorer COPM-P outcomes. The two regression models explained 38.3% and 38.8% of the total variance of the dependent variables of occupational performance and satisfaction with that performance, respectively.The results indicate that diagnosis, functional level, sex and motivation are significant predictors of outcomes following reablement.
