Background Falls are a major safety concern in healthcare. In palliative care, patients are particularly vulnerable due to complex symptom burdens and rapid physical decline. However, standard falls risk assessment tools, primarily designed for acute clinical environments, rely on static risk scores and lack efficacy in hospice settings. The Falls Early Warning Score (FEWS) is a observational tool developed to address the specific contributing factors and complex needs of palliative patients. Aims To explore and understand staff views regarding the implementation, utility, and benefits of the FEWS tool to identify people at risk of falling in a specialist palliative care inpatient unit. Methods A mixed-methods study was conducted at a UK hospice. Healthcare professionals with clinical experience using the FEWS chart completed an electronic questionnaire assessing their confidence, practice, and perceived barriers. Questionnaire outcomes informed subsequent face-to-face, semi-structured interviews. Qualitative data were evaluated using reflexive thematic analysis. Results Eleven staff completed the questionnaire, and five participated in interviews. Three major themes were identified: (1) Education, highlighting staff preferences for 1:1 training and the necessity of dedicated user guides; (2) Location and format of the FEWS tool, contrasting the data collection benefits of electronic formats against the bedside accessibility of paper charts; and (3) Recognised benefits of the FEWS tool, including its ability to prompt safe staffing levels, highlight variable patient presentation, and mitigate the emotional and physical impact of falls. Conclusions It is feasible and highly acceptable to integrate bespoke falls risk assessment tools into palliative care. By addressing the unique complexities of hospice patients, customised tools like FEWS can empower staff and support dynamic clinical decision-making. Further research is required to evaluate their clinical efficacy in reducing falls.

Background Chronic pain is common in adults aged 85 years and older (85+) and is associated with detrimental outcomes. Chronic pain guidelines advise first line management with non-pharmacological measures; paracetamol and non-steroidal anti-inflammatory drugs are the preferred analgesics. Challenges in accessing non-pharmacological therapies for adults aged 85+, and the presence of multimorbidity and polypharmacy, mean that opioid medication is often prescribed for chronic pain despite the potential for opioid-related adverse effects and guidance identifying long-term opioids for chronic pain as a potentially inappropriate prescription. Aim This study aims to explore patient, caregiver, and healthcare professional perspectives on the prescription of opioid medications for pain management for chronic pain in adults aged 85+ to support development of resources for optimising opioid prescribing. Design and Setting In this qualitative study, participants were recruited through primary care, in the community or in care home settings. Method 36 semi-structured interviews were conducted with care home residents and community dwellers aged 85+ (n=12), caregivers (informal and care home staff) (n=12), and healthcare professionals (n=12). Interviews were transcribed and analysed using reflexive thematic analysis. Results Four themes were developed: contextual complexity, satellite influences, balancing act, and pragmatic prescribing. Using opioids in adults aged 85+ is a balancing act to support patients best possible quality of life within their unique circumstances whilst using the pain management tools available. Conclusion Opioids continue to have an important role in pain management in adults aged 85+ largely due to paucity of alternatives and the drive to support quality of life.

Background: Wheeled walkers can improve safety during walking, but improper use may increase fall risk among frail older adults. No suitable tool exists to assess safe indoor wheeled walker use in this population. This study aimed to develop and validate a video-based expert assessment tool. Methods: Based on the literature and expert consensus, seven problematic indoor situations were identified, and an assessment tool with five safety criteria per situation was developed (maximum score = 35). Fifty participants (mean age 83.9 years, 64% women) from a geriatric rehabilitation clinic and a nursing home were video-recorded while using a rollator. Expert ratings were compared with nursing staff ratings, self-ratings, and the Timed Up and Go test to evaluate validity. Intra- and inter-rater reliability were determined from independent ratings by two physiotherapists and a repeated expert rating after seven days. Sensitivity to change was assessed after two weeks of rehabilitation, and feasibility by the time required for assessment. Results: The expert score of rater 1 at baseline was 28.5 points, and assessment required a mean of 17.5 minutes. Intra-rater reliability was excellent (ICC = 0.98) and inter-rater reliability was good (ICC = 0.80). Validity analyses showed the strongest association with nursing staff assessments (r = 0.74) and a moderate association with the Timed Up and Go test (r = -0.45). After two weeks, patients improved by an average of 2.38 points (8.4% of baseline score). Conclusions: The new instrument demonstrated high reliability, acceptable validity, sensitivity to change, and good feasibility for assessing safe wheeled walker use in frail older adults.

Relatively little is known regarding suicide among older adults in nursing homes. The aim of this study was to compare the incidence of suicide among older nursing home residents (NHR) with community-dwelling older people (CDP) using newly available, national, individual-level register data, and to assess differences with regard to socio-demographic characteristics. We obtained data on all older adults aged 65+ who were living in Austria at the end of October 2018 (n=1,665,450), including 155,020 NHR. Death by suicide was followed until the end of 2023. A total of 114 and 2,136 suicides were observed among NHR and CDP; corresponding to cumulative incidences of 14 and 27 per 100,000, respectively. Among NHR, suicide incidence was higher among males (28.0, 95% CI=22.1, 35.5), those aged 65-74 years (20.2, 95% CI=13.3, 30.6), with tertiary education (23.3, 95% CI=10.6, 50.6), divorced (25.0, 95% CI=16.2, 38.5), and residing in urban nursing homes (22.0, 95% CI=17.0, 28.4). Compared to CDP, more suicides in NHR occurred by poisoning and but few by firearms. In conclusion, we found that suicide incidence was lower among older NHR compared to CDP. More research on and preventive efforts against suicide among older NHR are needed.

BACKGROUND: Aging is associated with a progressive decline in cognitive performance and functional autonomy, both closely related to frailty. Understanding the interrelation between these domains is essential to identify modifiable factors influencing cognitive impairment in older adults. OBJECTIVES: To evaluate the relationship between physical frailty, cognitive performance, and functional dependence, and to identify sociodemographic and clinical variables associated with cognitive impairment in community-dwelling older adults. DESIGN: Cross-sectional study. SETTING: FREEDOM-LNA cohort, a population-based study conducted by the University Hospital of Limoges, France. PARTICIPANTS: A total of 753 community-dwelling older adults aged [≥]75 years, or [≥]65 years with at least two comorbidities, were included. MEASUREMENTS: Cognitive function was assessed using the Mini Mental State Examination (MMSE), 5-word test (5WT), clock drawing test (CDT), and verbal fluency tests. Frailty was defined according to Frieds physical criteria, and functional independence was evaluated using ADL and IADL scales. Sociodemographic, clinical, and lifestyle factors were analyzed using multivariate models to identify predictors of cognitive impairment. RESULTS: Of the participants, 34.4% had a pathologic MMSE, 46.0% failed the CDT, 68.0% the verbal fluency test, and 17.0% the 5WT. Cognitive performance was significantly lower among frail compared to prefrail and robust individuals. Older adults with pathologic cognition were more frequently dependent in activities of daily living. Independent predictors of poor cognitive performance included non-modifiable factors (age, sex, education) and modifiable ones (low BMI, hypertension, alcohol consumption, smoking, and polypharmacy). CONCLUSIONS: Cognitive impairment was highly prevalent among frail older adults and was strongly associated with loss of independence. Interventions targeting modifiable risk factors such as low BMI, hypertension, alcohol consumption, and smoking may help preserve cognitive and functional abilities in aging populations. Interventions to improve BMI and reduce alcohol consumption, smoking, and hypertension may preserve cognition in older adults.

Background: Non-motor symptoms, including sleep and cognitive dysfunction, are major contributors to reduced quality of life in people with Parkinsons disease (PwPD). Dance has been proposed as a promising intervention to improve quality of life in PwPD. Previously, we reported longitudinal trajectories of global cognition following community-based dance; however, little is known about its long-term influence on sleep-related non-motor symptoms and their relationship with global cognitive performance. Objective: We examined the six-year trajectories of sleep and overall non-motor symptom severity among PwPD participating in weekly community-based dance classes compared to a sedentary Reference group. As a secondary objective, we evaluated their association with global cognitive performance as a functional outcome. Methods: This longitudinal observational study followed PwPD engaged in community dance participation as well as a matched sedentary control group from the Parkinsons Progression Markers Initiative database over six years. Generalized estimating equations (GEE) were used to model group-level trends, with sensitivity analyses conducted to assess the robustness of the findings. Results: Non-motor outcomes showed that insomnia worsened significantly within the Reference group (p = .003) but improved among dancers (p = .005), with daytime sleepiness remaining stable across both groups. When sleep was used as a predictor of cognition, global cognitive performance trended to improve in the Dance group (p = .078) and declined mid-period in the Reference group (p = .014). In addition, overall non-motor symptom severity worsened in the Reference group (p = .011) but remained stable in the Dance group. Constipation also worsened significantly in the Reference group (p = .012) compared to the Dance group. Conclusion: The present study demonstrates that community-based dance may support select non-motor symptoms, including insomnia, and cognitive resilience in PwPD. Findings reinforce dance as a valuable, real-world, non-pharmacological approach to slow functional decline in PD.

Older adults in residential care are usually described as a group at high risk of undernutrition, yet data on the nutritional and cardiometabolic status of institutionalised older adults in Central Asia are scarce. We aimed to characterise the anthropometric, dietary and biochemical profile of older residents of a state social-care institution in Kazakhstan and to examine whether overnutrition, micronutrient inadequacy and cardiometabolic risk coexist. In this cross-sectional study, 62 adults aged 60 years and over from the "Sharapat" centre in Astana underwent anthropometry, bioelectrical impedance body-composition analysis, blood-pressure measurement, dietary assessment (specialized nutrition questionnaires, a 24-hour dietary recall and food diaries) with calculation of nutrient intakes, and venous blood and urine testing; serum 25-hydroxyvitamin D and trace elements were measured in 29 participants. Laboratory analyses and data processing were performed at the Research Institute of Preventive Medicine named after E.D. Dalenov, Astana Medical University. The sample (61.3% men; mean age 74.0 years) showed a high cardiometabolic burden, with arterial hypertension in 63%, total cholesterol of at least 5.0 mmol/L in 60%, LDL-cholesterol of at least 3.0 mmol/L in 71%, and overweight or obesity in 58%, whereas only 5% were underweight. Habitual diets were high in sodium (71% above 2000 mg/day) and low in potassium (92% below 3500 mg/day), calcium (85% below 1000 mg/day) and fibre (90% below 25 g/day). Among those tested, 79% had vitamin D deficiency, and overweight or obesity coexisted with vitamin D deficiency in 16 of 29 participants. None of 56 exploratory diet-risk correlations survived correction for multiple testing. Rather than the undernutrition typical of residential care, these residents displayed a double burden of malnutrition-excess adiposity and cardiometabolic risk alongside micronutrient-poor diets and widespread vitamin D deficiency-identifying concrete targets for institutional catering, supplementation and cardiometabolic screening.

Background: Hearing loss (HL) may be a risk factor for poor psychosocial outcomes among older adults, but evidence remains mixed. We assessed associations of self-reported and objective HL with and without hearing aid use with social contact, loneliness, and depression pooled across 6 years of follow-up. Methods: We studied 2049 Black and White adults from the Health, Aging, and Body Composition study aged 70-79 at recruitment. Self-reported HL and audiometric HL with and without hearing aid use were assessed at analytic baseline (Year 5, 2001-2002). Outcomes were frequency of contact with family and friends (<weekly vs. at least weekly), depressive symptoms (CESD-10), and loneliness (CESD-10 item "I felt lonely") measured across 6 annual visits. Adjusted for demographic and clinical variables, we used generalized linear regression with generalized estimating equations to assess associations with outcomes pooled across six follow-up waves. Results: Self-reported HL (16%) was associated with more depressive symptoms ({beta}=0.13 SD; 95%CI:0.03,0.24), but no other outcome. Objective HL without hearing aid use (11%) was associated with infrequent contact with friends (OR=1.38; 95%CI:1.07,1.78) and more depressive symptoms ({beta}=0.19 SD; 95%CI:0.07,0.31); objective HL with hearing aid use (9%) was not associated with these outcomes. Objective HL, regardless of hearing aid use, was borderline associated with more frequent feelings of loneliness. Discussion: Objective HL without hearing aid use may be an important risk factor for isolation from friendship networks and depressive symptoms among older adults. Self-reported HL and objective HL with hearing aid use may also be linked to some adverse psychosocial outcomes.

Background Delirium is common among hospitalized older adults on many clinical services and associated with poor outcomes. Given delirium's fluctuations, wearable devices are promising continuous monitors. While recruiting for a wearable electroencephalography (EEG) delirium study, we initially experienced low enrollment rates among older adults and patients on non-neurologic services. Our aim was to understand patient and community perspectives on inpatient, wearable research to adapt recruitment protocols and increase enrollment. Methods We approached patients admitted to an academic medical center to participate in an observational, wearable EEG delirium study and recorded reasons for enrolling or declining. To gain insight into recruitment protocols, we held a community panel with patients, family members, and caregivers. Recruitment protocols were refined in two phases: 1) personalizing the recruitment approach to emphasize symptoms that were personally relevant to individual patients and 2) sharing educational materials about the study in addition to delirium. We compared enrollment rates before and after these protocol adaptations. Results Initially, 18.5% of approached patients enrolled (68/367). Despite antecedent concerns that wearable devices would be the primary deterrent to participation, only a small proportion of people who did not participate did so because of wearable EEG (8.8%, 26/299). Community panel members (n=7) suggested that personal relevance and understanding of the clinical conditions being studied, such as delirium, would have a greater impact on decisions to participate than study procedures. Adapting recruitment protocols to highlight personally relevant delirium-related symptoms, such as sleep disturbance, significantly increased enrollment rates (30.1%, 58/188, p<0.001), including for patients over 65 years old (p<0.001) and patients on non-neurologic services (p<0.001). The addition of educational materials focused on clinical delirium did not further impact enrollment (p=0.61). Conclusions Recruitment of older, hospitalized patients for inpatient research can be challenging, but can be significantly improved by highlighting familiar symptoms of personal relevance.

Background Older adults evaluated by consultation-liaison psychiatry services (CLPS) often present with complex psychiatric and medical comorbidity, frequent psychotropic exposure and a high prevalence of frailty. However, the relative contribution of these factors to clinical outcomes remains unclear. Methods We conducted a multicentre prospective cohort study including 465 consecutive patients aged more than 65 years evaluated by CLPS in 10 general hospitals in Spain between January and July 2024. Psychiatric history, postconsultation psychiatric diagnoses, psychotropic use, age group (65-74 vs older than 75 years) and frailty assessed using the Clinical Frailty Scale were recorded. Outcomes included falls, institutionalisation, access to mental health follow-up and mortality at 1 and 3 months after discharge. Results The mean (SD) age was 77.4 (7.8) years and 55.9% were women. Psychiatric history was present in 68.8% of patients and 55.8% received a new psychiatric diagnosis, most commonly delirium. Psychotropic use was frequent (71.6%), particularly antidepressants (49.0%) and benzodiazepines (42.6%). Psychotropic polypharmacy was associated with falls. Frailty was prevalent (60.2%) and independently associated with early mortality, whereas age was the main predictor of mortality between 1 and 3 months. Older age was also associated with a lower likelihood of specialised mental health follow-up. Conclusions Among older adults evaluated by CLPS, frailty and medical comorbidity appear to outweigh psychiatric variables in predicting outcomes. Integrating comprehensive geriatric assessment and medication review into CLPS may improve care for this population.

Background Falls in hospitals are associated with injuries, deaths and poor patient outcomes. Although clinical guidelines recommend educating hospital patients about how to prevent falls, not all hospitals systematically deliver evidence-based patient falls education. The primary aim of this study is to implement and evaluate the effectiveness of delivering a research-informed education program called the Safe Recovery Program with ward support on rates of falls and falls-related injuries in hospitals. The secondary aims include measuring changes in patient and staff knowledge and awareness about falls prevention and identifying barriers and facilitators to staff and patients taking action to reduce hospital falls. Methods The trial will adhere to the Consolidated Standards of Reporting Trials guidelines. Twelve wards will be recruited from five Australian hospitals over a 65-week period. A stepped-wedge cluster randomised controlled trial design will be used with unidirectional crossover from control to experimental conditions together with randomisation of when each cluster makes the transition. The crossovers will occur at 12 timepoints, each five weeks apart. Alongside the trial, patients and staff on participating wards will be recruited for interviews and qualitative data analyses will be conducted to understand how to optimise implementation. The experimental condition involves usual care plus delivery of the Safe Recovery Program. For the Safe Recovery Program, supervised allied health assistants will deliver brief falls education programs to all suitable patients in designated wards, reinforced by all ward staff. Falls champions, who are registered nurses and allied health professionals, will provide Safe Recovery Program training for staff, using a train-the-trainer model. The ward staff will also be trained in how to support hospital patients to adopt safe behaviours. The primary outcome will be falls per 1000 patient bed days. The secondary outcomes will be: (i) injurious falls per 1000 patient bed days (ii) patient and staff changes in falls awareness, knowledge and motivation; and (iii) barriers and enablers to hospital staff engaging in behaviour change and program implementation. An economic evaluation will also be conducted to estimate the incremental cost effectiveness of implementing the Safe Recovery intervention. Ethics and Dissemination Ethics approvals have been obtained from The Royal Melbourne Hospital Human Research Ethics Committee (HREC/113864/MH-2024). The findings will be disseminated through peer-reviewed journals, workshops and conferences. Consumer team investigators will guide the communication of findings to the target audiences, including older patients, hospital staff, healthcare managers and policy makers.

Background: People affected by dementia experience intersecting care inequalities. We explored relationships between ethnicity and health and social care resource use among people with dementia in an ethnically diverse urban region. Methods: We conducted a retrospective observational cohort study using Discover-NOW, including patients with dementia between 1.4.2015 and 1.4.2025. We calculated ethnic density as the percentage of the Middle Layer Super Output Area (SOA) population self-identifying with the same ethnic group. Regression models, clustered by Local SOA, tested whether ethnic density moderated relationships between ethnicity and primary care, outpatient, inpatient, emergency and social care service use, controlling for sociodemographic characteristics, deprivation, comorbidities and time of diagnosis. Findings: We included 30,704 people with dementia. People from Black and Mixed ethnic groups used more primary care, and those from Asian ethnic groups less primary and secondary care, than White ethnic groups. Rates of local authority social care packages were similar across ethnic groups. High ethnic density predicted fewer GP consultations in Black ethnic groups, but more in South Asian groups. Interpretation: Among Black ethnic groups, primary care use was relatively high, especially in areas of low ethnic density, perhaps reflecting greater needs among communities at risk of racism and isolation. The trend towards increased primary care use among South Asian people in areas of higher ethnic density may reflect communities mitigating help-seeking hesitancy related to cultural and language barriers. Greater care integration could reduce care inequalities among minority ethnic communities who may experience fewer barriers to social relative to health care.

Background: In the UK, over 36 million contacts are made annually by people living with dementia (PLWD) to either primary or secondary community mental health services. As dementia progresses, PLWD may experience increased distress and resort to 999 calls for an ambulance, which may in turn result in conveyance to Accident & Emergency (A&E). Nearly 1 million A&E attendances are made by PLWD. This trend is set to rise sharply as the prevalence rates of dementia increase over time and as the condition progresses, with associated healthcare costs impacting overall care delivery. This may lead to reduced resource allocation for dementia emergency services, negatively affecting the experiences of both providers and service users. Aim(s): To explore ways to improve access and quality of care to emergency crisis care for PLWD from the perspective of healthcare staff providing this type of support. Methods: This qualitative study explored (1) the experiences, resources, and needs of healthcare professionals in emergency and community settings to support access for PLWD, and (2) the mechanisms influencing dementia crisis response. The COREQ Checklist was used to improve transparency, credibility, and reproducibility. Inter-rater reliability was calculated. PPIE contributors co-developed recommendations for healthcare professionals, and study findings informed a comic-based dissemination resource shared with third-sector organisations to support community awareness and engagement. Results: Fifteen interviews were held with emergency services staff. Inter-rater reliability was substantial between two raters (k = 0.62). Four overarching themes, with associated subthemes, were identified relating to crisis care delivery, barriers to effective response, and strategies employed to address these challenges. Additional themes captured decision-making processes at key points in the care pathway, including initial crisis response, during intervention, and at discharge from emergency and community services. Decision-making was characterised by the need to balance patient safety with autonomy in determining care in the best interests of PLWD and their informal carers. Discussion: This exploratory study reveals frontline staff perspectives on challenges and actionable strategies for dementia crisis care. Findings support targeted service improvements, cross-sector collaboration, and co-produced resources to enhance outcomes for PLWD and their informal carers.

Background: Polypharmacy is an escalating global health challenge, yet longitudinal evidence regarding its impact on mortality in Latin American aging populations remains limited. This study evaluated the association between medication burden and all cause mortality among community dwelling older adults in a rapidly aging region of Colombia. Methods: A longitudinal analysis was conducted using a sub-cohort of 4,110 participants (aged 60 years or more) from the SABE Colombia survey (Antioquia, Caldas, Risaralda, and Quindio). Vital status was adjudicated via the National Health System Resources Administrator (ADRES) database over a mean follow-up of 79 months. Polypharmacy was defined as the concurrent use of 5 9 medications and excessive polypharmacy as 10 or more. Extended Cox proportional hazards models were employed to estimate hazard ratios (HR), adjusting for sociodemographic factors, multimorbidity, and functional dependency. Results: At baseline, 20.2% of participants presented polypharmacy and 2.1% excessive polypharmacy. A total of 1,092 deaths (26.6%) were recorded during follow-up. After multivariable adjustment, both moderate polypharmacy (HR 1.17; 95% CI 1.02 - 1.31; p=0.029) and excessive polypharmacy (HR 1.82; 95% CI 1.34 - 2.47; p<0.001) were identified as independent predictors of mortality. Notably, the risk was markedly higher at the 10 or more medication threshold, suggesting a non-linear relationship between pharmacological burden and survival. Conclusions: Polypharmacy is a significant and independent predictor of mortality in Colombian older adults, with the risk nearly doubling in cases of excessive medication use. These findings underscore the urgent need for structured medication review and deprescribing interventions tailored to resource-constrained healthcare systems to mitigate the risks associated with high pharmacological accumulation. Keywords: Polypharmacy, Aged, Mortality, Longitudinal, Colombia.

Background Population aging is rapidly increasing the burden of multimorbidity and frailty, yet there is limited evidence on how healthy aging policies are implemented across different demographic and health system contexts. Methods We conducted a mixed-methods comparative case study in Spain, Italy, Chile, and Colombia, integrating a Targeted review of policy documents and relevant literature, quantitative indicators, and expert interviews. Results Chile and Colombia showed faster aging dynamics (compound annual growth rates of 4.18% and 4.21%) than Italy (1.96%) and Spain (1.39%), with estimated doubling times of 17 versus 36-50 years. All four countries have established policy frameworks; implementation remains uneven. Key barriers included fragmented services, limited community care, workforce constraints, and misaligned financing. Conclusions The central challenge lies not in the absence of policy frameworks but in their effective implementation. Strengthening primary care, embedding frailty assessment, and improving health-social care integration are key priorities for systems facing rapid demographic transition.

Background: Existing electronic frailty indices (eFI) are typically based on structured data and designed for older adults. We developed an eFI that integrates structured and unstructured electronic health records (EHRs) across adulthood and assessed its longitudinal trajectories and associations with adverse outcomes. Methods: We used longitudinal EHR data from 193629 individuals aged 35-103 in the Wellbeing Services County of Central Finland (2010-2023) and constructed a 53-item eFI including diagnosis codes, laboratory tests and items extracted from free-text clinical notes using deep-learning-based natural language processing. Associations with all-cause mortality, severe infections, fractures, and healthcare utilization were assessed using Cox and count models. Predictive performance was compared with Hospital Frailty Risk Score (HFRS) and Charlson Comorbidity Index (CCI). Findings: eFI trajectories accelerated notably from age 65 onwards. Using the eFI as a categorical variable, severe frailty was associated with higher risks of mortality (hazard ratio [HR] 7.31, 95% confidence interval [CI] 6.83-7.83), severe infections (HR 9.22, 95%CI 8.52-9.98), fractures (HR 2.75, 95%CI 2.52-3.01) and increased healthcare utilization (odds ratio [OR] 3.15, 95%CI 2.96-3.35) compared with non-frail. The risks were relatively greater in younger age groups and persisted when using the continuous eFI restricted to non-frail individuals. Across all outcomes, the eFI showed greater model discrimination than HFRS and CCI. Interpretation: An eFI using structured and unstructured EHR data improves risk stratification even in younger adults and at very low levels of frailty.

Objectives: To estimate hyperlipidemia medication order prevalence and associated variables in U.S. skilled nursing facility (SNF) residents. Design: Retrospective, observational study. Setting and Participants: Electronic Health Record data from 447,080 SNF residents with a hyperlipidemia diagnosis identified in PointClickCare's Life Sciences clinical database (January-April 2025) were reviewed. Methods: The presence and absence of medication orders for hyperlipidemia treatments recommended by the American Heart Association were assessed. Descriptive analyses summarized demographic and clinical characteristics, and a modified Poisson regression model was used to estimate risk ratios for having a medication order, adjusting for demographic, clinical, and facility characteristics. Results: Overall, 83.3% of residents diagnosed with hyperlipidemia had at least one hyperlipidemia medication order. Statins were ordered by 96.2% of active order residents, while other medication classes i.e., omega-3 fatty acids, cholesterol absorption inhibitors, fibrates were less common (<8%). Risk ratios (RRs) for medication orders ranged from 0.87-1.16. Factors most strongly associated with having an order included hypertension medication orders (RR=1.16), unspecified hyperlipidemia diagnosis (RR=1.10), and active diabetes medication orders (RR=1.09); female sex (RR=0.95) and private (0.94) or other (0.87) payer types were associated with a lower likelihood of having an order. Conclusions and Implications: Most residents with a hyperlipidemia diagnosis had an active relevant medication order, but use of non-statin therapies was rare. Differences in treatment patterns by sex and payer type, along with limited uptake of newer agents, warrant further investigation into prescribing practices and access within SNFs.

Objectives: The 10-item Centre for Epidemiological Studies Depression Scale (CES-D-10) has been used in cohort studies with scores of >= 8 and >= 10 used to indicate clinically significant symptoms or probable depression. We examined whether observations crossing these thresholds displayed core affective features expected in individuals who might be suffering with a clinically significant major depressive episode. Methods: This was a descriptive analysis of repeated CES-D-10 assessments in the ASPirin in Reducing Events in the Elderly eXTension (ASPREE-XT) longitudinal cohort study of 19,114 participants. We identified observations of 'probable depression', defined as a CES-D-10 score >= 8 and then examined scores on item 3 ("I felt depressed") and item 8 ("I was happy"). The primary outcome was the proportion of threshold-positive CES-D-10 observations with minimally depressed mood and preserved happiness. Results: Over 13 years, 27,417 observations met the threshold of CES-D-10 >= 8. Of these, 13,356 observations (48.7%) had minimally depressed mood and preserved happiness. Conclusion: A substantial proportion of observations considered 'probable depression' had little or no depressed mood, together with preserved happiness. CES-D-10 sum scores should be used with caution as a proxy for major depressive disorder in older adults.

Background: Palliative care services appear less able to reach people from ethnically diverse communities and if they do, people from these communities report having different and often poorer experiences. The barriers to access are well described so research investigating potential solutions is needed. Aims: To understand how improved palliative care outcomes for people from ethnically diverse communities have or could be achieved, and what contextual issues have influenced these outcomes. Methods: Qualitative multiple case study. The cases were defined as areas across England with services providing generalist or specialist palliative care to adults and/or children. Interviews were conducted with patients, family carers, parents (from ethnically diverse communities), health and social care professionals. Data were analysed using thematic framework analysis. Findings: Cases (n=6) included 71 participants. Five solution focused themes were identified; how the conditions for culturally and spiritually safe care are created; engagement and trust building between ethnically diverse communities and the providers that serve them as a mechanism to promote access; workforce composition and diversity helping to bridge the gap between ethnically diverse communities and services; how communication practices enable equitable care for people who have English as an additional language and organisational commitment and partnership as drivers of sustainable change. Conclusions: Equitable access to quality palliative care is not a marginal policy issue with the economic and moral argument for change strong. Care systems need to recognise, partner with, and build upon existing community strengths. Change requires intent, accountability, leadership and the reallocation of attention and responsibility.

Background Falls are a leading cause of injury-related hospital admissions among older adults with substantial burden on health and social care systems. Digital exercise programmes may improve physical function at scale and complement traditional services. Keep-On-Keep-Up (KOKU) is an NHS-approved digital programme offering progressive, evidence-based exercises and education on fall prevention. We aimed to evaluate the effectiveness and cost-effectiveness of KOKU for improving balance, physical function and reducing fall risk among community-dwelling older adults. Methods A two-arm, parallel group randomised controlled trial was conducted with community-dwelling older adults (>=60 years). Participants were randomised (1:1) to receive KOKU alongside standard care (strength and balance exercise advice and a falls prevention leaflet) or standard care alone. The primary outcome was balance function at 12 weeks (Berg Balance Score). Secondary outcomes included lower limb strength, concerns about falling, falls, mood, pain, fatigue, healthcare utilisation, health-related quality of life and usability. A modified intention-to-treat approach was used to analyse effectiveness and cost effectiveness. Results A total of 202 older adults (mean age 76.8 years, 72.8% female) were enrolled (102 intervention; 100 control). Retention at 12-weeks was 89.1% (91 intervention; 89 control). Compared with standard care, KOKU significantly improved balance function at 12 weeks after adjusting for baseline scores (mean difference: 6.35, 95% CI: 4.48, 8.22). KOKU was associated with lower mean falls related costs (incremental cost (GBP): -62.98, 95% CI -218.54 to 40.22) and a QALY gain of 0.020 (95% CI 0.003 to 0.035). Conclusion The KOKU programme improves balance with preliminary evidence of cost-effectiveness among community-dwelling older adults.
