Protocol for a systematic review and meta-analysis of the prevalence of mental illness among nursing home residents

BACKGROUND

There is a high prevalence of mental illness in nursing home residents compared to older adults living in the community. This was highlighted in the most recent comprehensive systematic review on the topic, published in 2010. In the context of a rapidly aging population and increased numbers of older adults requiring residential care, this study aims to provide a contemporary account of the prevalence of mental illness among nursing home residents.

METHODS

This protocol was prepared in line with the PRISMA-P 2015 Statement. Systematic searches will be undertaken across six electronic databases: PubMed, Embase, Web of Science, PsycNET, CINAHL, and Abstracts in Social Gerontology. Peer-reviewed studies published from 2009 onwards which report the prevalence of mental illness within nursing home populations will be included. Database searches will be supplemented by forward and backward citation searching. Titles and abstracts of records will be screened using a semi-automated process. The full text of selected records will be assessed to confirm inclusion criteria are met. Study selection will be recorded in a PRISMA flowchart. A pilot-tested form will be used to extract data from included studies, alongside the JBI Critical Appraisal Checklist for Studies Reporting Prevalence Data. A study characteristics and results table will be prepared to present key details from each included study, supported by a narrative synthesis. Random-effects restricted maximum likelihood meta-analyses will be performed to compute pooled prevalence estimates for mental illnesses represented in the identified studies. Heterogeneity will be assessed using Cochran's Q and Higgins' I2 statistics. A Funnel plot and Egger's test will be used to assess publication bias. The GRADE approach will be used to assess the quality of the body of evidence identified.

DISCUSSION

The study will provide a comprehensive and contemporary account of the prevalence of mental illness among nursing home residents. Meta-analyses will provide robust prevalence estimates across a range of presentations. Key insights will be highlighted, including potential sources of heterogeneity. Implications for residents, researchers, care providers, and policymakers will be noted.

Study protocol for ELders AT Ease (ELATE): a cluster randomised controlled trial of cognitive behaviour therapy to reduce depressive symptoms in aged care residents

BACKGROUND

This protocol describes a study of the effectiveness of cognitive behaviour therapy (CBT) for reducing depressive symptoms in older adults living in residential aged care (RAC) facilities in Australia. Depressive symptoms are highly prevalent in this population, yet the benefits of CBT for reducing such symptoms in RAC facilities have not been widely investigated. Elders at Ease (ELATE) is a 16-session CBT intervention designed for implementation in RAC facilities. The intervention includes cognitive, behavioural and reminiscence strategies and is delivered by mental health trainees (MHTs) in collaboration with RAC facility staff and residents' family.

METHODS AND ANALYSIS

ELATE will be evaluated using a cluster randomised trial comparing outcomes for residents who participate in the intervention with those living in usual care control facilities. The participants are RAC residents aged 65 years or above, with depressive symptoms (Patient Health Questionnaire-2 ≥ 3) and normal cognition or mild cognitive impairment (Standardised Mini Mental Status Examination ≥ 21). They are assessed at four time points: baseline prior to randomisation (T1), mid-treatment (T2; 2.5 months post randomisation), post-treatment (T3; 5 months post-randomisation) and 3-month follow-up (T4; 8 months post randomisation). The primary outcome is change in depressive symptoms between T1 and T3. Secondary outcomes are depressive symptoms at T4, anxiety, suicide ideation, sleep problems, quality of life, staff and family knowledge of late-life depression, stress levels and efficacy in caring for residents, and MHT levels of geropsychology competencies. Residents receiving the intervention are hypothesised to report a greater decrease in depressive symptoms between T1 and T3 compared to residents receiving usual care. The primary analysis is a regression, clustered over site to account for correlated readings, and independent variables are condition and depressive symptoms at T1. A cost-utility analysis is also undertaken.

DISCUSSION

ELATE is a comprehensive CBT intervention for reducing depressive symptoms in RAC residents. It is designed to be implemented in collaboration with facility staff and residents' families, individually tailored to residents with normal cognition to mild cognitive impairment and delivered by trainee therapists. ELATE offers a model that may be widely applicable across the RAC sector.

Characteristics and effectiveness of cognitive behavioral therapy for older adults living in residential care: a systematic review

OBJECTIVES

Cognitive behavioral therapy (CBT) for depression and anxiety for older adults living in residential aged care facilities (RACFs) needs to accommodate the care needs of residents and the circumstances of RACFs. This systematic review examines the delivery and content characteristics of these interventions, in relation to participant satisfaction, staff appraisal, uptake rate, attrition rate, and treatment effectiveness. Such a review could provide important information for the development of future CBT-based interventions.

METHOD

Studies that examined the application of CBT for depression or anxiety in RACFs were identified by systematically searching a number of relevant databases. Reference lists of all included studies were examined, and citation searches on the Web of Science were conducted. Two independent reviewers were involved in screening articles and in extracting data and assessing methodological quality of the selected studies.

RESULTS

Across the 18 studies included in this review, the most common therapeutic strategy was pleasant activities scheduling. Studies varied on treatment duration (2-24 weeks), number of sessions (6-24), and length of sessions (10-120 min). Residents and staff members were satisfied with the CBT interventions. The average uptake rate was 72.9%. The average attrition rate was 19.9%. Statistically significant results were reported in 8 of the 12 randomized controlled trials (RCTs). In these eight RCTs, CBT was characterized by psychoeducation, behavioral activation, and problem-solving techniques; further, the therapists in six of these studies had training in psychology.

CONCLUSION

CBT interventions for depression and anxiety are acceptable to RACF residents and judged positively by staff members. Effective studies differed from non-effective studies on content and training characteristics, but not on other delivery features.

Characteristics of Cognitive Behavioral Therapy for Older Adults Living in Residential Care: Protocol for a Systematic Review

Background

The prevalence rates of depressive and anxiety disorders are high in residential aged care settings. Older adults in such settings might be prone to these disorders because of losses associated with transitioning to residential care, uncertainty about the future, as well as a decline in personal autonomy, health, and cognition. Cognitive behavioral therapy (CBT) is efficacious in treating late-life depression and anxiety. However, there remains a dearth of studies examining CBT in residential settings compared with community settings. Typically, older adults living in residential settings have higher care needs than those living in the community. To date, no systematic reviews have been conducted on the content and the delivery characteristics of CBT for older adults living in residential aged care settings.

Objective

The objective of this paper is to describe the systematic review protocol on the characteristics of CBT for depression and/or anxiety for older adults living in residential aged care settings.

Methods

This protocol was developed in compliance with the recommendations of the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols (PRISMA-P). Studies that fulfill the inclusion criteria will be identified by systematically searching relevant electronic databases, reference lists, and citation indexes. In addition, the PRISMA flowchart will be used to record the selection process. A pilot-tested data collection form will be used to extract and record data from the included studies. Two reviewers will be involved in screening the titles and abstracts of retrieved records, screening the full text of potentially relevant reports, and extracting data. Then, the delivery and content characteristics of different CBT programs of the included studies, where available, will be summarized in a table. Furthermore, the Downs and Black checklist will be used to assess the methodological quality of the included studies.

Results

Systematic searches will commence in May 2018, and data extraction is expected to commence in July 2018. Data analyses and writing will happen in October 2018.

Conclusions

In this section, the limitations of the systematic review will be outlined. Clinical implications for treating late-life depression and/or anxiety, and implications for residential care facilities will be discussed.

The use of cognitive behaviour therapy in the management of BPSD in dementia (Innovative practice)

Psychosocial approaches to the management of behavioural and psychological symptoms of dementia have received much support in the scientific literature. The following paper focuses on cognitive behaviour therapy as a valid framework in assessing and treating people with behavioural and psychological symptoms of dementia. The importance of identifying symptoms of depression and anxiety is emphasized, as cognitive behaviour therapy has been shown to be an effective intervention for these conditions in older adults. Modifications of cognitive behaviour therapy for those with dementia are discussed based on available evidence, with emphasis on incorporating nursing home staff in treatment programs and focusing on behavioural elements of cognitive behaviour therapy such as activity scheduling. The paper concludes with suggestions regarding how to incorporate and promote the use of cognitive behaviour therapy in dementia care settings.

Staff's views on managing symptoms of dementia in nursing home residents

Aim To identify the most common and distressing behavioural and psychological symptoms of dementia (BPSD) in nursing homes and to identify staff preferences regarding its behavioural management. Method A descriptive cross-sectional survey was completed by a self-selected sample of 247 staff working in 21 nursing homes in a defined catchment area. The survey contained items relating to experience in aged care work, attitudes towards BPSD, ratings of the importance of certain behavioural strategies for managing BPSD, and the Challenging Behaviour Scale. Results Shouting, wandering and restlessness had the highest incidence, frequency and difficulty ratings. Frequency of BPSD and level of satisfaction with how they were managed had the greatest effect on overall level of difficulty in managing behaviours. Staff rated discussing behavioural concerns at a group level and with senior nursing staff as the most important behavioural strategies. Conclusion A strong relationship was found between frequency and difficulty of BPSD. Therefore, interventions targeted at lowering frequency of BPSD are recommended. Communication across a number of levels may enhance the implementation of behavioural interventions.

Longitudinal study of cerebral blood flow in Alzheimer's disease using single photon emission tomography

Ten patients with probable Alzheimer's disease were assessed at baseline and a mean 2 years later using a battery of neuropsychological tests, CT scans and Tc99m-HMPAO SPECT scans. The subjects had declined significantly in their functional indices. Cerebral perfusion measures declined in the parietal lobes, left hemisphere and whole brain, but the overall decline did not reach statistical significance. The decline in brain perfusion did not correlate significantly with the decline in various indices of neuropsychological function, either globally or for specific brain regions. The index of cerebral perfusion correlated significantly with global indices of neuropsychological function at baseline but not at follow-up. No single perfusion index was a significant predictor of clinical progression of dementia.
