Behavioural activation in nursing homes to treat depression (BAN-Dep): study protocol for a pragmatic randomised controlled trial.

INTRODUCTION: Depression is a common disorder among older people living in residential aged care facilities. Several trials have demonstrated the effectiveness of behavioural therapies in treating depressive symptoms in older adults living in the community and in residential aged care. Behavioural Activation is demonstrably effective even when delivered by non-specialists (staff without formal psychological training), although strategies for adapting its use in residential aged care facilities are yet to be explored. This study will determine whether training residential care staff in the use of a structured Behavioural Activation programme is more effective at decreasing depressive symptoms among older residents than internet-based training about depression recognition and management alone. METHOD AND ANALYSIS: The behavioural activation in nursing homes to treat depression (BAN-Dep) trial is a pragmatic two-arm parallel clustered randomised controlled trial. It will recruit 666 residents aged 60 or older from 100 residential aged care facilities, which will be randomly assigned to the Behavioural Activation or control intervention. Staff in both treatment groups will be encouraged to complete the Beyondblue Professional Education to Aged Care e-learning programme to improve their recognition of and ability to respond to depression in older adults. Selected staff from intervention facilities will undergo additional training to deliver an 8-module Behavioural Activation programme to residents with subthreshold symptoms of depression-they will receive ongoing Mental support from trained Behavioural Activation therapists. Outcome measures will be collected by blind research officer at baseline and after 3, 6 and 12 months. The Patient Health Questionnaire-9 is the primary outcome measure of the study. ETHICS AND DISSEMINATION: The trial will comply with the principles of the Declaration of Helsinki for Human Rights and is overseen by the University of Western Australia (reference RA/4/20/4234) and Melbourne Health (reference number HREC/18/MH/47) Ethics Committees. The results of this research project will be disseminated through publications and/or presentations in a variety of media to health professionals, academics, clinicians and the public. Only de-identified group data will be presented. TRIAL REGISTRATION: ACTRN12618000634279.

Stakeholder perceptions on resident-to-resident aggression: implications for prevention.

Objective Resident-to-resident aggression (RRA) in nursing homes is a matter of serious and profound concern, yet action to eliminate or mitigate RRA is hampered by a paucity of research. The aim of this study was to explore key stakeholders' knowledge and perceptions of RRA in Australian nursing homes. Methods A qualitative cross-sectional study design was used, and semistructured telephone interviews were conducted. Participants were purposively and conveniently sampled with replacement from a range of aged care, healthcare and legal professional bodies, as well as advocacy organisations. The interview contained 12 closed-ended questions and six open-ended questions about participants' knowledge, experiences, perceptions and attitudes to RRA. Participant characteristics and responses to closed-ended questions were aggregated and proportions calculated, and thematic analysis was conducted by two independent researchers using a directed content approach. Results Fifteen participants (11 females; 73.3%) in senior management positions were interviewed. All were familiar with the concept of RRA and just over half (n=8; 53.3%) had witnessed an incident. Major themes included the nature and causes of RRA and attitudes and responses to RRA. Potential causes of RRA included maladaptation to nursing home life, transfer of pre-existing issues into the nursing home environment, physical environment and staffing-related issues. RRA was commonly viewed by participants as dangerous and unpredictable or, conversely, as expected behaviour in a nursing home setting. A person-centred care approach was considered most effective for managing and responding to RRA. Conclusion The research demonstrates that understanding perceptions of RRA among key stakeholders is critical to identifying the nature and scope of the problem and to developing and implementing appropriate prevention strategies. What is known about the topic? RRA is common in nursing homes, with potentially fatal consequences for residents involved, and has serious implications for nursing home staff, managers, providers, and regulators. Despite this, the prevalence, impact, and prevention of RRA remains under-recognised and under-researched in Australia. What does this paper add? This is the first Australian study to produce qualitative findings on the knowledge and perceptions of RRA in nursing homes among key stakeholders. This paper reports on the knowledge and perceptions of individuals in senior management and policy roles in aged care and related fields in relation to four themes: nature; causes; attitudes; and responses to RRA. Our findings highlight the complex and multifactorial nature of RRA. What are the implications for practitioners? A movement towards person-centred care that promotes understanding of individual care needs is favoured as an approach to reducing RRA. Increased reporting of both minor and major incidents of RRA will help to identify patterns and inform appropriate responses. However, a cultural shift is first required to recognise RRA as a manageable and preventable health care and adult safeguarding issue.

Prevalence and incidence of frailty in Aboriginal Australians, and associations with mortality and disability.

OBJECTIVES: Frailty represents a loss of homeostasis, markedly increasing the risk of death and disability. Frailty has been measured in several ethnic groups, but not, to our knowledge, in Aboriginal Australians. We aimed to determine the prevalence and incidence of frailty, and associations with mortality and disability, in remote-living Aboriginal people. STUDY DESIGN: Between 2004 and 2006, we recruited 363 Aboriginal people aged ≥ 45 years from 6 remote communities and one town in the Kimberley region of Western Australia (wave 1). Between 2011 and 2013, 182 surviving participants were followed-up (wave 2). We assessed frailty with an index, comprising 20 health-related items. Participants with ≥ 4 deficits (frailty index ≥ 0.2) were considered frail. Disability was assessed by family/carer report. Those unable to do ≥ 2 of 6 key or instrumental activities of daily living were considered disabled. We investigated associations between frailty, and disability and mortality, with logistic regression and Cox proportional hazards models. RESULTS: At wave 1 (W1), 188 participants (65.3%) were frail, and of robust people at W1 who participated in wave 2, 38 (51.4%) had become frail. Frailty emerged at a younger age than expected. A total of 109 people died (30.0%), of whom 80 (73.4%) were frail at W1. Frailty at W1 was not associated with becoming disabled, but was associated with mortality (HR = 1.9; 95% CI 1.2, 3.0). CONCLUSIONS: Frailty in remote-living Aboriginal Australians is highly prevalent; substantially higher than in other populations. Research to understand the underlying causes of frailty in this population, and if possible, reverse frailty, is urgently needed.

Incidence and predictors of cognitive impairment and dementia in Aboriginal Australians: A follow-up study of 5 years.

INTRODUCTION: Aboriginal Australians are reported to develop dementia earlier than the general population. The causes remain unknown. METHODS: This was a longitudinal study of 363 participants aged ≥45 years. Consensus diagnoses were established for cognitive impairment or dementia. RESULTS: At follow-up, 189 people (mean ± standard deviation age, 65.4 ± 10.3 years) participated, as 109 (30%) had died and 65 (18%) were unavailable. The incidence of cognitive impairment or dementia was 52.6 (95% confidence interval 33.9, 81.5) per 1000 person-years (380.3 total person-years) and for dementia was 21.0 (10.5, 42.1) per 1000 person-years (380.3 person-years total) over the age 60 years. Longitudinal risk factors associated with a decline from normal cognition to impairment were age and head injury. Other associations with cognitive decline were stroke, head injury, nonaspirin analgesics, lower BMI, and higher systolic BP. DISCUSSION: Dementia incidence in Aboriginal Australians is among the highest in the world, and is associated with age and head injury.

The combination of cognitive testing and an informant questionnaire in screening for dementia.

AIM: A cognitive test and an informant report questionnaire were used together to investigate whether their combined use could improve the accuracy of detecting dementia in a memory clinic, compared with either test used alone. METHOD: The subjects were 323 patients assessed at a memory clinic. The Mini-Mental State Examination and the short form of the Informant Questionnaire on Cognitive Decline in the Elderly were used. A method of combining the test scores developed by Mackinnon and Mulligan [Am J Psychiatry 1998; 155: 1529-35] was used. Dementia was diagnosed according to Diagnostic and Statistical Manual of Mental Disorders, Third Edition-Revised criteria. RESULTS: Logistic regression analysis showed that the combination of the Mini-Mental State Examination and the Informant Questionnaire on Cognitive Decline in the Elderly produced a slightly more accurate prediction of dementia caseness than either test used alone. Using receiver operating characteristic analysis the performance of the combination of the tests according to a weighted sum rule was compared with the performance of either test used alone. This way of combining the tests resulted in a more accurate screening for dementia than when the Informant Questionnaire on Cognitive Decline in the Elderly was used alone. The area under the receiver operating characteristic curve for the Mini-Mental State Examination combined with the Informant Questionnaire on Cognitive Decline in the Elderly was 0.89 compared with 0.82 for the Informant Questionnaire on Cognitive Decline in the Elderly alone (chi-square = 10.63; P = 0.0011). However, there was no improvement in screening performance when the combination of Mini-Mental State Examination and Informant Questionnaire on Cognitive Decline in the Elderly was compared with the Mini-Mental State Examination used alone (area under the receiver operating characteristic curve = 0.89 versus 0.86; chi-square = 3.54; P = 0.060). CONCLUSION: The combination of cognitive testing and an informant report according to a weighted sum rule in this population did not result in any advantage over the use of the Mini-Mental State Examination alone. The mixed results of this study contrast with those of Mackinnon and Mulligan.
