Background: Admitting people with dementia to critical care units may not always lead to a clear survival benefit. Critical care admissions of people with dementia vary across countries. Little is known about the use and trends of critical care admissions of people with dementia in England., Objective: To investigate critical care use and survival among people with dementia in a large London catchment area., Methods: A retrospective cohort study using data from dementia assessment services in south London, UK (2007-20) linked with national hospitalisation data to ascertain critical care admissions. Outcomes included age-sex-standardised critical care use and 1-year post-critical care admission survival by dementia severity (binary: mild versus moderate/severe). We used logistic regression and Kaplan-Meier survival plots for investigating 1-year survival following a critical care admission and linear regressions for time trends., Results: Of 19,787 people diagnosed with dementia, 726 (3.7%) had ≥1 critical care admission at any time after receiving their dementia diagnosis. The overall 1-year survival of people with dementia, who had a CCA, was 47.5% (n = 345). Dementia severity was not associated with 1-year survival following a critical care admission (mild dementia versus moderate-severe dementia odds of 1-year mortality OR: 0.90, 95% CI [0.66-1.22]). Over the 12-year period from 2008 to 2019, overall critical care use decreased (β = -0.05; 95% CI = -0.01, -0.0003; P = 0.03), while critical care admissions occurring during the last year of life increased (β = 0.11, 95% CI = 0.01, 0.20, P = 0.03)., Conclusions: In this cohort, while critical care use among people with dementia declined overall, its use increased among those in their last year of life. Survival remains comparable to that observed in general older populations., (© The Author(s) 2023. Published by Oxford University Press on behalf of the British Geriatrics Society.)

Background: emergency department (ED) visits have inherent risks for people with dementia yet increase towards the end-of-life. Although some individual-level determinants of ED visits have been identified, little is known about service-level determinants., Objective: to examine individual- and service-level factors associated with ED visits by people with dementia in the last year of life., Methods: retrospective cohort study using hospital administrative and mortality data at the individual-level, linked to health and social care service data at the area-level across England. The primary outcome was number of ED visits in the last year of life. Subjects were decedents with dementia recorded on the death certificate, with at least one hospital contact in the last 3 years of life., Results: of 74,486 decedents (60.5% women; mean age 87.1 years (standard deviation: 7.1)), 82.6% had at least one ED visit in their last year of life. Factors associated with more ED visits included: South Asian ethnicity (incidence rate ratio (IRR) 1.07, 95% confidence interval (CI) 1.02-1.13), chronic respiratory disease as the underlying cause of death (IRR 1.17, 95% CI 1.14-1.20) and urban residence (IRR 1.06, 95% CI 1.04-1.08). Higher socioeconomic position (IRR 0.92, 95% CI 0.90-0.94) and areas with higher numbers of nursing home beds (IRR 0.85, 95% CI 0.78-0.93)-but not residential home beds-were associated with fewer ED visits at the end-of-life., Conclusions: the value of nursing home care in supporting people dying with dementia to stay in their preferred place of care must be recognised, and investment in nursing home bed capacity prioritised., (© The Author(s) 2023.

Background: hospitalisations are sentinel events for people with dementia. How patterns of unplanned hospital admissions change among people with dementia after diagnosis is relatively unknown., Objective: to describe patterns of unplanned hospital admissions of people with dementia from diagnosis until death/study end., Methods: retrospective cohort study using mental healthcare provider data of people diagnosed with dementia in London, UK (1995-2017), linked to mortality and hospital data. The primary outcome was the rate of unplanned hospital admissions after diagnosis until death/study end. We calculated the cumulative incidence of unplanned hospital admissions. The rates of unplanned hospital admissions and the percentage of time spent as an inpatient were stratified by time from first dementia diagnosis., Results: for 19,221 people with dementia (61.4% female, mean age at diagnosis 81.0 years (standard deviation, SD 8.5)), the cumulative incidence of unplanned hospital admissions (n = 14,759) was 76.8% (95% CI 76.3%-77.3%). Individuals remained in the study for mean 3.0 (SD 2.6) years, and 12,667 (65.9%) died. Rates and lengths of unplanned hospital admissions remained relatively low and short in the months after the dementia diagnosis, increasing only as people approached the end of life. Percentage of time spent as an inpatient was <3% for people who were alive at the study end but was on average 19.6 and 13.3% for the decedents in the last 6 and 12 months of life, respectively., Conclusions: the steep rise in hospitalisations before death highlights the need for improved community care and services for people with dementia who are approaching the end of life., (© The Author(s) 2022.

Background: transitions between care settings near the end-of-life for people with dementia can be distressing, lead to physical and cognitive deterioration, and may be avoidable., Objective: to investigate determinants of end-of-life hospital transitions, and association with healthcare use, among people with dementia., Design: retrospective cohort study., Setting: electronic records from a mental health provider in London, linked to national mortality and hospital data., Subjects: people with dementia who died in 2007-2016., Methods: end-of-life hospital transitions were defined as: multiple admissions in the last 90 days (early), or any admission in the last three days of life (late). Determinants were assessed using logistic regression., Results: of 8,880 people, 1,421 (16.0%) had at least one end-of-life transition: 505 (5.7%) had early, 788 (8.9%) late, and 128 (1.5%) both types. Early transitions were associated with male gender (OR 1.33, 95% CI 1.11-1.59), age (>90 vs <75 years OR 0.69, 95% CI 0.49-0.97), physical illness (OR 1.52, 95% CI 1.20-1.94), depressed mood (OR 1.49, 95% CI 1.17-1.90), and deprivation (most vs least affluent quintile OR 0.58, 95% CI 0.37-0.90). Care home residence was associated with fewer early (OR 0.63, 95% CI 0.53 to 0.76) and late (OR 0.80, 95% CI 0.65 to 0.97) transitions. Early transitions were associated with more hospital admissions throughout the last year of life compared to those with late and no transitions (mean 4.56, 1.89, 1.60; P < 0.001)., Conclusions: in contrast to late transitions, early transitions are associated with higher healthcare use and characteristics that are predictable, indicating potential for prevention., (© The Author(s) 2019.

Background: dying in one's preferred place is a quality marker for end-of-life care. Little is known about preferred place of death, or the factors associated with achieving this, for people with dementia., Aims: to understand preferences for place of death among people with dementia; to identify factors associated with achieving these preferences., Population: adults with a diagnosis of dementia who died between December 2015 and March 2017 and who were registered on Coordinate My Care, an Electronic Palliative Care Coordination System., Design: retrospective cohort study., Analysis: multivariable logistic regression investigated factors associated with achieving preferred place of death., Results: we identified 1,047 people who died with dementia; information on preferred and actual place of death was available for 803. Preferred place of death was most commonly care home (58.8%, n = 472) or home (39.0%, n = 313). Overall 83.7% (n = 672) died in their preferred place. Dying in the preferred place was more likely for those most functionally impaired (OR 1.82 95% CI 1.06-3.13), and with a ceiling of treatment of 'symptomatic relief only' (OR 2.65, 95% CI 1.37-5.14). It was less likely for people with a primary diagnosis of cancer (OR 0.52, 95% CI 0.28-0.97), those who were 'for' cardio-pulmonary resuscitation (OR 0.32, 95% CI 0.16-0.62) and those whose record was created longer before death (51-250 days (ref <50 days) OR 0.60, 95% CI 0.38-0.94)., Conclusions: most people with dementia want to die in a care home or at home. Achieving this is more likely where goals of treatment are symptomatic relief only, indicating the importance of advance care planning., (© The Author(s) 2019.

Background: Emergency department (ED) attendance for older people towards the end of life is common and increasing, despite most preferring home-based care. We aimed to review the factors associated with older people's ED attendance towards the end of life., Methods: Systematic review using Medline, Embase, PsychINFO, CINAHL and Web of Science from inception to March 2017. Included studies quantitatively examined factors associated with ED attendance for people aged ≥65 years within the last year of life. We assessed study quality using the QualSyst tool and determined evidence strength based on quality, quantity and consistency. We narratively synthesized the quantitative findings., Results: Of 3824 publications identified, 21 were included, combining data from 1 565 187 participants. 17/21 studies were from the USA and 19/21 used routinely collected data. We identified 47 factors and 21 were included in the final model. We found high strength evidence for associations between ED attendance and palliative/hospice care (adjusted effect estimate range: 0.1-0.94); non-white ethnicity (1.03-2.16); male gender (1.04-1.83, except 0.70 in one sub-sample) and rural areas (0.98-1.79). The final model included socio-demographic, illness and service factors, with largest effect sizes for service factors., Conclusions: In this synthesis, receiving palliative care was associated with lower ED attendance in the last year of life for older adults. This has implications for service models for older people nearing the end of life. However, there is limited evidence from European countries and none from low or middle-income countries, which warrants further research.

Background: understanding how best to provide palliative care for frail older people with non-malignant conditions is an international priority. We aimed to develop a community-based episodic model of short-term integrated palliative and supportive care (SIPS) based on the views of service users and other key stakeholders in the United Kingdom., Method: transparent expert consultations with health professionals, voluntary sector and carer representatives including a consensus survey; and focus groups with older people and carers were used to generate recommendations for the SIPS model. Discussions focused on three key components of the model: potential benefit of SIPS, timing of delivery and processes of integrated working between specialist palliative care and generalist practitioners. Content and descriptive analysis was employed and findings were integrated across the data sources., Findings: we conducted two expert consultations (n = 63), a consensus survey (n = 42) and three focus groups (n = 17). Potential benefits of SIPS included holistic assessment, opportunity for end of life discussion, symptom management and carer reassurance. Older people and carers advocated early access to SIPS, while other stakeholders proposed delivery based on complex symptom burden. A priority for integrated working was the assignment of a key worker to co-ordinate care, but the assignment criteria remain uncertain., Interpretation: key stakeholders agree that a model of SIPS for frail older people with non-malignant conditions has potential benefits within community settings, but differ in opinion on the optimal timing and indications for this service. Our findings highlight the importance of consulting all key stakeholders in model development prior to feasibility evaluation., (© The Author 2016.

Background: mortality statistics are a frequently used source of information on deaths in dementia but are limited by concerns over accuracy., Objective: to investigate the frequency with which clinically diagnosed dementia is recorded on death certificates, including predictive factors., Methods: a retrospective cohort study assembled using a large mental healthcare database in South London, linked to Office for National Statistics mortality data. People with a clinical diagnosis of dementia, aged 65 or older, who died between 2006 and 2013 were included. The main outcome was death certificate recording of dementia., Results: in total, 7,115 people were identified. Dementia was recorded on 3,815 (53.6%) death certificates. Frequency of dementia recording increased from 39.9% (2006) to 63.0% (2013) (odds ratio (OR) per year increment 1.11, 95% CI 1.07-1.15). Recording of dementia was more likely if people were older (OR per year increment 1.02, 95% CI 1.01-1.03), and for those who died in care homes (OR 1.89, 95% CI 1.50-2.40) or hospitals (OR 1.14, 95% CI 1.03-1.46) compared with home, and less likely for people with less severe cognitive impairment (OR 0.95, 95% CI 0.94-0.96), and if the diagnosis was Lewy body (OR 0.30, 95% CI 0.15-0.62) or vascular dementia (OR 0.79, 95% CI 0.68-0.93) compared with Alzheimer's disease., Conclusions: changes in certification practices may have contributed to the rise in recorded prevalence of dementia from mortality data. However, mortality data still considerably underestimate the population burden of dementia. Potential biases affecting recording of dementia need to be taken into account when interpreting mortality data., (© The Author 2016.
