BACKGROUND AND OBJECTIVES:Human research ethics statements support equitable inclusion of diverse groups. Yet older people are under-represented in clinical research, especially those with impaired decision-making capacity. The aim of this study was to identify perspectives and experiences of older persons and their caregivers of research participation with impaired decision-making capacity. RESEARCH DESIGN AND METHODS:Scoping review of literature and online sources in January-February 2019 (updated June 2020) according to Joanna Briggs Institute methodology and PRISMA Extension for Scoping Reviews. English-language peer-reviewed research articles and Australian online narratives were included. Data were tabulated and narratively synthesized. RESULTS:From 4171 database records and 93 online resources, 22 articles (2000-2019, 82% United States, 16 first authors) and one YouTube webinar (2018) were initially included; updated searches yielded an additional article (2020) and YouTube webinar (2020). Studies were heterogeneous in terminology, methods and foci, with hypothetical scenarios, quantitative analyses and examination of proxy consent predominating. Participants (n=7331) were older persons (71%), caregivers of older persons with dementia/cognitive impairment (23%) and older persons with dementia/cognitive impairment (6%). Synthesis identified two themes: willingness to participate and decision-making approaches. DISCUSSION AND IMPLICATIONS:Research participation by older persons with dementia may be optimized through reducing risks and burdens and increasing benefits for participants, greater consumer input into study development, and shared and supported decision-making. Older persons' and caregivers' perspectives and experiences of research participation with impaired decision-making capacity require investigation in a greater range of countries and conditions other than dementia, and dissemination through more varied media.

INTRODUCTION:Delirium is a significant medical complication for hospitalised patients. Up to one-third of delirium episodes are preventable in older inpatients through non-pharmacological strategies that support essential human needs, such as physical and cognitive activity, sleep, hydration, vision and hearing. We hypothesised that a multicomponent intervention similarly may decrease delirium incidence, and/or its duration and severity, in inpatients with advanced cancer. Prior to a phase III trial, we aimed to determine if a multicomponent non-pharmacological delirium prevention intervention is feasible and acceptable for this specific inpatient group. METHODS AND ANALYSIS:The study is a phase II cluster randomised wait-listed controlled trial involving inpatients with advanced cancer at four Australian palliative care inpatient units. Intervention sites will introduce delirium screening, diagnostic assessment and a multicomponent delirium prevention intervention with six domains of care: preserving natural sleep; maintaining optimal vision and hearing; optimising hydration; promoting communication, orientation and cognition; optimising mobility; and promoting family partnership. Interdisciplinary teams will tailor intervention delivery to each site and to patient need. Control sites will first introduce only delirium screening and diagnosis, later implementing the intervention, modified according to initial results. The primary outcome is adherence to the intervention during the first seven days of admission, measured for 40 consecutively admitted eligible patients. Secondary outcomes relate to fidelity and feasibility, acceptability and sustainability of the study intervention, processes and measures in this patient population, using quantitative and qualitative measures. Delirium incidence and severity will be measured to inform power calculations for a future phase III trial. ETHICS AND DISSEMINATION:Ethical approval was obtained for all four sites. Trial r...

BACKGROUND:Delirium is common, distressing, serious and under-researched in specialist palliative care settings. OBJECTIVES:To examine whether people requiring palliative care were included in non-pharmacological delirium intervention studies in inpatient settings, how they were characterised and what their outcomes were. DESIGN:Systematic review (PROSPERO 2017 CRD42017062178). DATA SOURCES:Systematic search in March 2017 for non-pharmacological delirium intervention studies in adult inpatients. Database search terms were 'delirium', 'hospitalisation', 'inpatient', 'palliative care', 'hospice', 'critical care' and 'geriatrics'. Scottish Intercollegiate Guidelines Network methodological checklists guided risk of bias assessment. RESULTS:The 29 included studies were conducted between 1994 and 2015 in diverse settings in 15 countries (9136 participants, mean age = 76.5 years (SD = 8.1), 56% women). Most studies tested multicomponent interventions (n = 26) to prevent delirium (n = 19). Three-quarters of the 29 included studies (n = 22) excluded various groups of people requiring palliative care; however, inclusion criteria, participant diagnoses, illness severity and mortality indicated their presence in almost all studies (n = 26). Of these, 21 studies did not characterise participants requiring palliative care or report their specific outcomes (72%), four reported outcomes for older people with frailty, dementia, cancer and comorbidities, and one was explicitly focused on people receiving palliative care. Study heterogeneity and limitations precluded definitive determination of intervention effectiveness and only allowed interpretations of feasibility for people requiring palliative care. Acceptability outcomes (intervention adverse events and patients' subjective experience) were rarely reported overall. CONCLUSION:Non-pharmacological delirium interventions have frequently excluded and under-characterised people requiring palliative care and infrequently reported ...
