Hospitalisations and emergency department presentations by older individuals accessing long-term aged care in Australia.

Objective The study examined emergency department (ED) presentations, unplanned hospitalisations and potentially preventable hospitalisations in older people receiving long-term care by type of care received (i.e. permanent residential aged care or home care packages in the community), in Australia in 2019. Methods A retrospective cohort study was conducted using the Registry of Senior Australians National Historical Cohort. Individuals were included if they resided in South Australia, Queensland, Victoria or New South Wales, received a home care package or permanent residential aged care in 2019 and were aged ≥65 years. The cumulative incidence of ED presentations, unplanned hospitalisations and potentially preventable hospitalisations in each of the long-term care service types were estimated during the year. Days in hospital per 1000 individuals were also calculated. Results The study included 203,278 individuals accessing permanent residential aged care (209,639 episodes) and 118,999 accessing home care packages in the community (127,893 episodes). A higher proportion of people accessing home care packages had an ED presentation (43.1% [95% confidence interval, 42.8-43.3], vs 37.8% [37.6-38.0]), unplanned hospitalisation (39.8% [39.6-40.1] vs 33.4% [33.2-33.6]) and potentially preventable hospitalisation (11.8% [11.6-12.0] vs 8.2% [8.1-8.4]) than people accessing permanent residential aged care. Individuals with home care packages had more days in hospital due to unplanned hospitalisations than those in residential care (7745 vs 3049 days/1000 individuals). Conclusions While a high proportion of older people in long-term care have ED presentations, unplanned hospitalisations and potentially preventable hospitalisations, people in the community with home care packages experience these events at a higher frequency.

Assessing the reach and safety of an innovative urgent care service tailored to older adults.

Traditional emergency departments (EDs) are overcrowded and sometimes not suitable for older adults with complex needs. Specialised geriatric urgent care pathways for selected patients can alleviate ED demand and improve patient experience. To address urgent care needs for older adults in Southern Adelaide, the Complex And RestorativE (CARE) service was established. CARE offers alternative, geriatrician-led treatment pathways consisting of a ward-based treatment centre and an in-home visiting team called Eyes on Scene (EoS). Both pathways offer medical, nursing and allied health treatment. Routinely collected clinical data were analysed to explore the reach of the service and the incidence and nature of adverse events. Between September 2021 and March 2023, the CARE service attended to 5324 older adults requiring urgent care. A significant proportion of patients were discharged to or remained in their regular place of residence, with few requiring inpatient admissions or referrals to other facilities. A total of 7% of patients required transfer to ED and adverse events were rare. The CARE service demonstrates a feasible and safe alternative model of urgent care for older Australians.

The risk of fractures after entering long-term care facilities.

BACKGROUND: Stratifying residents at increased risk for fractures in long-term care facilities (LTCFs) can potentially improve awareness and facilitate the delivery of targeted interventions to reduce risk. Although several fracture risk assessment tools exist, most are not suitable for individuals entering LTCF. Moreover, existing tools do not examine risk profiles of individuals at key periods in their aged care journey, specifically at entry into LTCFs. PURPOSE: Our objectives were to identify fracture predictors, develop a fracture risk prognostic model for new LTCF residents and compare its performance to the Fracture Risk Assessment in Long term care (FRAiL) model using the Registry of Senior Australians (ROSA) Historical National Cohort, which contains integrated health and aged care information for individuals receiving long term care services. METHODS: Individuals aged ≥65 years old who entered 2079 facilities in three Australian states between 01/01/2009 and 31/12/2016 were examined. Fractures (any) within 365 days of LTCF entry were the outcome of interest. Individual, medication, health care, facility and system-related factors were examined as predictors. A fracture prognostic model was developed using elastic nets penalised regression and Fine-Gray models. Model discrimination was examined using area under the receiver operating characteristics curve (AUC) from the 20 % testing dataset. Model performance was compared to an existing risk model (i.e., FRAiL model). RESULTS: Of the 238,782 individuals studied, 62.3 % (N = 148,838) were women, 49.7 % (N = 118,598) had dementia and the median age was 84 (interquartile range 79-89). Within 365 days of LTCF entry, 7.2 % (N = 17,110) of individuals experienced a fracture. The strongest fracture predictors included: complex health care rating (no vs high care needs, sub-distribution hazard ratio (sHR) = 1.52, 95 % confidence interval (CI) 1.39-1.67), nutrition rating (moderate vs worst, sHR = 1.48, 95%CI 1.38-1.59), prior fractures (sHR ranging from 1.24 to 1.41 depending on fracture site/type), one year history of general practitioner attendances (≥16 attendances vs none, sHR = 1.35, 95%CI 1.18-1.54), use of dopa and dopa derivative antiparkinsonian medications (sHR = 1.28, 95%CI 1.19-1.38), history of osteoporosis (sHR = 1.22, 95%CI 1.16-1.27), dementia (sHR = 1.22, 95%CI 1.17-1.28) and falls (sHR = 1.21, 95%CI 1.17-1.25). The model AUC in the testing cohort was 0.62 (95%CI 0.61-0.63) and performed similar to the FRAiL model (AUC = 0.61, 95%CI 0.60-0.62). CONCLUSIONS: Critical information captured during transition into LTCF can be effectively leveraged to inform fracture risk profiling. New fracture predictors including complex health care needs, recent emergency department encounters, general practitioner and consultant physician attendances, were identified.

Cohort profile: GRACE - a residential aged care cohort examining factors influencing antimicrobial resistance carriage.

BACKGROUND: The emergence of antimicrobial-resistant bacteria represents a considerable threat to human health, particularly for vulnerable populations such as those living in residential aged care. However, antimicrobial resistance carriage and modes of transmission remain incompletely understood. The Generating evidence on antimicrobial Resistance in the Aged Care Environment (GRACE) study was established to determine principal risk factors of antimicrobial resistance carriage and transmission in residential aged care facilities (RACFs). This article describes the cohort characteristics, national representation, and planned analyses for this study. METHODS: Between March 2019 and March 2020, 279 participants were recruited from five South Australian RACFs. The median age was 88.6 years, the median period in residence was 681 days, and 71.7% were female. A dementia diagnosis was recorded in 54.5% and more than two thirds had moderate to severe cognitive impairment (68.8%). 61% had received at least one course of antibiotics in the 12 months prior to enrolment. RESULTS: To investigate the representation of the GRACE cohort to Australians in residential aged care, its characteristics were compared to a subset of the historical cohort of the Registry of Senior Australians (ROSA). This included 142,923 individuals who were permanent residents of RACFs on June 30th, 2017. GRACE and ROSA cohorts were similar in age, sex, and duration of residential care, prevalence of health conditions, and recorded dementia diagnoses. Differences were observed in care requirements and antibiotic exposure (both higher for GRACE participants). GRACE participants had fewer hospital visits compared to the ROSA cohort, and a smaller proportion were prescribed psycholeptic medications. CONCLUSIONS: We have assembled a cohort of aged care residents that is representative of the Australian aged care population, and which provides a basis for future analyses. Metagenomic data isolated from participants and built environments will be used to determine microbiome and resistome characteristics of an individual and the facility. Individual and facility risk exposures will be aligned with metagenomic data to identify principal determinants for antimicrobial resistance carriage. Ultimately, this analysis will inform measures aimed at reducing the emergence and spread of antimicrobial resistant pathogens in this high-risk population.

Evaluating a new emergency department avoidance service for older people: patient and relative experiences.

BACKGROUND: High emergency department (ED) usage by older individuals for non-emergencies is a global concern. ED avoidance initiatives have proven effective in addressing this issue. To specifically cater to individuals aged 65 and above, the Southern Adelaide Local Health Network introduced an innovative ED avoidance service. This study assessed the acceptability of the service among its users. METHOD: The Complex And RestorativE (CARE) Centre is a six-bed unit staffed by a multidisciplinary geriatric team. Patients are transported directly to CARE after calling for an ambulance and being triaged by a paramedic. The evaluation took place between September 2021 and September 2022. Semi-structured interviews were conducted with patients and relatives who had accessed the service. Data analysis was performed using a six-step thematic analysis. RESULTS: Seventeen patients and 15 relatives were interviewed, who described the experience of 32 attendances to the urgent CARE centre between them. Patients accessed the service for several reasons but over half were associated with falls. There was a hesitation to call emergency services for several reasons, the primary being long wait times in ED and/or the prospect of an overnight stay in hospital. Some individuals attempted to contact their General Practitioner (GP) for the presenting problem but were unable to get a timely appointment. Most participants had previously attended a local ED and had a negative experience. All individuals reported favouring the CARE centre over the traditional ED for numerous reasons including a quieter and safer environment and specially trained geriatric staff who were less rushed than ED staff. Several participants would have appreciated a standardised follow-up process after discharge. CONCLUSION: Our findings suggest that ED admission avoidance programmes may be an acceptable alternative treatment for older people requiring urgent care, potentially benefiting both public health systems and user experience.

Exploring the role of a facilitator in supporting family carers when embedding the iSupport for Dementia programme in care services: A qualitative study.

AIMS: To explore stakeholders' perceptions of a facilitator's role in supporting carers when embedding iSupport for Dementia psychoeducation program, in care services. METHODS: A qualitative descriptive study design was applied. Data were collected from workshops and interviews with carers of people living with dementia (PLWD)and with health and social care professionals from two tertiary hospitals and two community aged care organisations across three Australian states between October 2021 and March 2022. A thematic analysis was used to analyse data. The COREQ guideline was followed to report our findings. RESULTS: A total of 30 family carers and 45 health and social care professionals participated in the study. Three main themes and seven subthemes were identified from the data. We described the main themes as (1) the facilitator's role at the time of dementia diagnosis, (2) the facilitator's role throughout the everyday dementia care journey and (3) the facilitator's role during transition moments. CONCLUSIONS: Caring for family members with dementia is demanding and stressful for carers. Embedding a facilitator-enabled iSupport for Dementia program in hospital and community aged care settings has the potential to mitigate sources of stress associated with care recipient factors, carer factors and care service factors, and improve the health and well-being of carers and those for whom they care. RELEVANCE TO CLINICAL PRACTICE: Our findings will inform the establishment of iSupport facilitators appointed by dementia care providers in hospital and community care settings and help determine their roles and responsibilities in delivering the iSupport program. Our findings relate to nurse-led and coordinated dementia care in hospital and community aged care settings. PATIENT OR PUBLIC CONTRIBUTION: This study was co-designed with stakeholders from two aged care organisations and two tertiary hospitals. The study participants were staff employed by these organisations and carers of PLWD who were service users.

Quality and safety in residential aged care: an evaluation of a national quality indicator programme.

BACKGROUND: In Australia, 243 000 individuals live in approximately 2700 residential aged care facilities yearly. In 2019, a National Aged Care Mandatory Quality Indicator programme (QI programme) was implemented to monitor the quality and safety of care in facilities. AIM: To examine the validity of the QI programme indicators using explicit measure review criteria. METHODS: The QI programme manual and reports were reviewed. A modified American College of Physicians Measure Review Criteria was employed to examine the QI programme's eight indicators. Five authors rated each indicator on importance, appropriateness, clinical evidence, specifications and feasibility using a nine-point scale. A median score of 1-3 was considered to not meet criteria, 4-6 to meet some criteria and 7-9 to meet criteria. RESULTS: All indicators, except polypharmacy, met criteria (median scores = 7-9) for importance, appropriateness and clinical evidence. Polypharmacy met some criteria for importance (median = 6, range 2-8), appropriateness (median = 5, range 2-8) and clinical evidence (median = 6, range 3-8). Pressure injury, physical restraints, significant unplanned weight loss, consecutive unplanned weight loss, falls and polypharmacy indicators met some criteria for specifications validity (all median scores = 5) and feasibility and applicability (median scores = 4 to 6). Antipsychotic use and falls resulting in major injury met some criteria for specifications (median = 6-7, range 4-8) and met criteria for feasibility and applicability (median = 7, range 4-8). CONCLUSIONS: Australia's National QI programme is a major stride towards a culture of quality promotion, improvement and transparency. Measures' specifications, feasibility and applicability could be improved to ensure the programme delivers on its intended purposes.

Death by suicide among aged care recipients in Australia 2008-2017.

OBJECTIVE: To characterize the features of aged care users who died by suicide and examine the use of mental health services and psychopharmacotherapy in the year before death. DESIGN: Population-based, retrospective exploratory study. SETTING AND PARTICIPANTS: Individuals who died while accessing or waiting for permanent residential aged care (PRAC) or home care packages in Australia between 2008 and 2017. MEASUREMENTS: Linked datasets describing aged care use, date and cause of death, health care use, medication use, and state-based hospital data collections. RESULTS: Of 532,507 people who died, 354 (0.07%) died by suicide, including 81 receiving a home care package (0.17% of all home care package deaths), 129 in PRAC (0.03% of all deaths in PRAC), and 144 approved for but awaiting care (0.23% of all deaths while awaiting care). Factors associated with death by suicide compared to death by another cause were male sex, having a mental health condition, not having dementia, less frailty, and a hospitalization for self-injury in the year before death. Among those who were awaiting care, being born outside Australia, living alone, and not having a carer were associated with death by suicide. Those who died by suicide more often accessed Government-subsidized mental health services in the year before their death than those who died by another cause. CONCLUSIONS: Older men, those with diagnosed mental health conditions, those living alone and without an informal carer, and those hospitalized for self-injury are key targets for suicide prevention efforts.

Development of a Multivariable Prediction Model for Risk of Hospitalization With Pressure Injury After Entering Residential Aged Care.

OBJECTIVES: Although largely preventable, pressure injury is a major concern in individuals in permanent residential aged care (PRAC). Our study aimed to identify predictors and develop a prognostic model for risk of hospitalization with pressure injury (PI) using integrated Australian aged and health care data. DESIGN: National retrospective cohort study. SETTING AND PARTICIPANTS: Individuals ≥65 years old (N = 206,540) who entered 1797 PRAC facilities between January 1, 2009, and December 31, 2016. METHODS: PI, ascertained from hospitalization records, within 365 days of PRAC entry was the outcome of interest. Individual, medication, facility, system, and health care-related factors were examined as predictors. Prognostic models were developed using elastic nets penalized regression and Fine and Gray models. Area under the receiver operating characteristics curve (AUC) assessed model discrimination out-of-sample. RESULTS: Within 365 days of PRAC entry, 4.3% (n = 8802) of individuals had a hospitalization with PI. The strongest predictors for PI risk include history of PIs [sub-distribution hazard ratio (sHR) 2.41; 95% CI 1.77-3.29]; numbers of prior hospitalizations (having ≥5 hospitalizations, sHR 1.95; 95% CI 1.74-2.19); history of traumatic amputation of toe, ankle, foot and leg (sHR 1.72; 95% CI 1.44-2.05); and history of skin disease (sHR 1.54; 95% CI 1.45-1.65). Lower care needs at PRAC entry with respect to mobility, complex health care, and medication assistance were associated with lower risk of PI. The risk prediction model had an AUC of 0.74 (95% CI 0.72-0.75). CONCLUSIONS AND IMPLICATIONS: Our prognostic model for risk of hospitalization with PI performed moderately well and can be used by health and aged care providers to implement risk-based prevention plans at PRAC entry.

Consumer and Healthcare Professional Led Priority Setting for Quality Use of Medicines in People with Dementia: Gathering Unanswered Research Questions.

BACKGROUND: Historically, research questions have been posed by the pharmaceutical industry or researchers, with little involvement of consumers and healthcare professionals. OBJECTIVE: To determine what questions about medicine use are important to people living with dementia and their care team and whether they have been previously answered by research. METHODS: The James Lind Alliance Priority Setting Partnership process was followed. A national Australian qualitative survey on medicine use in people living with dementia was conducted with consumers (people living with dementia and their carers including family, and friends) and healthcare professionals. Survey findings were supplemented with key informant interviews and relevant published documents (identified by the research team). Conventional content analysis was used to generate summary questions. Finally, evidence checking was conducted to determine if the summary questions were 'unanswered'. RESULTS: A total of 545 questions were submitted by 228 survey participants (151 consumers and 77 healthcare professionals). Eight interviews were conducted with key informants and four relevant published documents were identified and reviewed. Overall, analysis resulted in 68 research questions, grouped into 13 themes. Themes with the greatest number of questions were related to co-morbidities, adverse drug reactions, treatment of dementia, and polypharmacy. Evidence checking resulted in 67 unanswered questions. CONCLUSION: A wide variety of unanswered research questions were identified. Addressing unanswered research questions identified by consumers and healthcare professionals through this process will ensure that areas of priority are targeted in future research to achieve optimal health outcomes through quality use of medicines.

Aged and Health Care Service Utilization by Older Australians Receiving Home Care Packages.

OBJECTIVES: To examine the (1) cohort of individuals living at home with Home Care Packages (HCPs) in 2016, (2) their access to other aged care services after HCP commencement, and (3) their hospital and ambulance service utilization. DESIGN: A cross-sectional study was conducted using integrated aged care and health care data contained within the National Historical Cohort of the Registry of Senior Australians. SETTING AND PARTICIPANTS: This study included people who accessed HCP between January 1, 2016 and December 31, 2016. METHODS: The access to permanent residential aged care, transition care, respite care, hospital and ambulance services among Australian HCP recipients ≥65 years old in 2016 was evaluated. Descriptive statistics were employed. RESULTS: In 2016, 84,681 individuals received HCPs, of which 68.4% (n = 57,942) accessed HCP levels 1‒2, 26.0% (n = 22,057) accessed HCP levels 3‒4, and 5.5% (n = 4682) accessed both care levels within the year. Of the individuals receiving HCP, 34.0% (n = 27,787) started services that year and 16.7% (n = 14,117) moved to permanent residential aged care, 18.4% (n = 15,592) used respite care and 5.8% (n = 4937) used transition care that year. Emergency department (ED) presentations [43.6%, 95% confidence interval (CI) 43.3‒44.0] were the most common hospital encounters, followed by inpatient hospitalizations for any reason (43.3%, 95% CI 42.9‒43.7), and unplanned hospitalizations (38%, 95% CI 37.6‒38.3). Forty-four percent (44.5%, 95% CI 43.9‒45.0) of individuals utilized ambulance services. ED presentations, hospitalization for any reason, and unplanned hospitalizations were more common in individuals receiving HCP levels 3‒4 compared with those accessing HCP levels 1‒2. CONCLUSIONS AND IMPLICATIONS: HCP recipients in Australia have frequent hospitalizations, including ED presentations. In addition, almost 1 in 5 access respite care and 16.7% transition to permanent residential care each year. As the population accessing HCP is increasing, adequate support for these individuals to live well at home and avoid health events that lead to hospitalizations are necessary.

A systematic review and meta-analysis of reablement interventions for people in permanent residential aged care homes.

BACKGROUND: Most evidence for reablement comes from community-based interventions. OBJECTIVE: To determine the effect of reablement interventions provided in permanent residential aged care (PRAC) homes on residents' level of function in activities of daily living (ADL) and quality of life (QoL). DESIGN: Systematic review and meta-analysis. SETTING: PRAC homes. SUBJECTS: Residents in PRAC. METHODS: Six databases and grey literature were searched until November 2021. Quantitative studies involving a control group or pre-post evaluation were included. Outcomes of interest were the effectiveness of the reablement intervention on overall ADL or QoL in the last available follow-up. RESULTS: Twelve studies involving 2,620 residents were included. The reablement interventions varied; the primary focus areas were organisational approaches (e.g. educating staff; n = 10) and improving physical function (e.g. increasing physical activity; n = 9). Not all studies could be pooled in the meta-analysis due to reported data and heterogeneity. There was no significant effect of reablement intervention versus usual care on ADL function (five studies, standardised mean difference (SMD): 0.17, 95% confidence interval (CI): -0.25 to 0.59, very low quality evidence). Reablement appeared more beneficial than usual care in improving QoL; however, the overall effect was not statistically significant (four studies, SMD: 0.73, 95% CI: -0.07 to 1.52; very low quality evidence). CONCLUSIONS: Few studies focus on reablement in PRAC homes and their clinical heterogeneity is considerable. There is insufficient evidence for reablement in terms of improving ADL or QoL for residents in PRAC. Tools that are more sensitive to change may be beneficial.

Creating 'Partnership in iSupport program' to optimise family carers' impact on dementia care: a randomised controlled trial protocol.

BACKGROUND: The majority of people with dementia are cared for by their family members. However, family carers are often unprepared for their caring roles, receiving less education and support compared with professional carers. The consequences are their reduced mental and physical health and wellbeing, and that of care recipients. This study protocol introduces the 'Partnership in iSupport program' that includes five interventional components: managing transitions, managing dementia progression, psychoeducation, carer support group and feedback on services. This health services research is built on family carer and dementia care service provider partnerships. The aims of the study are to evaluate the effectiveness, cost-effectiveness and family carers' experiences in the program. METHODS: A multicentre randomised controlled trial will be conducted with family carers of people living with dementia from two tertiary hospitals and two community aged care providers across three Australian states. The estimated sample size is 185 family carers. They will be randomly assigned to either the intervention group or the usual care group. Outcomes are measurable improvements in quality of life for carers and people with dementia, caregiving self-efficacy, social support, dementia related symptoms, and health service use for carers and their care recipients. Data will be collected at three time points: baseline, 6 months and 12 months post-initiation of the intervention. DISCUSSION: This is the first large randomised controlled trial of a complex intervention on health and social care services with carers of people living with dementia in real-world practice across hospital and community aged care settings in three Australian states to ascertain the effectiveness, cost-effectiveness and carers' experiences of the innovative program. We expect that this study will address gaps in supporting dementia carers in health and social care systems while generating new knowledge of the mechanisms of change in the systems. Findings will strengthen proactive health management for both people living with dementia and their carers by embedding, scaling up and sustaining the 'Partnership in iSupport program' in the health and social care systems.

Associations between Cognitive Function, Hospitalizations and Costs in Nursing Homes: A Cross-sectional Study.

In an Australian nursing home population, associations between cognitive function and 12-month hospitalizations and costs were examined. Participants with dementia had 57% fewer hospitalizations compared to those without dementia, with 41% lower mean hospitalization costs; poorer cognition scores were also associated with fewer hospitalizations. The cost per admission for those with dementia was 33% greater due to longer hospital stays (5.5 days versus 3.1 days for no dementia, p = .05). People with dementia were most frequently hospitalized for fractures. These findings have policy implications for increasing investment in accurate and timely diagnosis of dementia and fall and fracture prevention strategies to further reduce associated hospitalization costs.

The risk of fall-related hospitalisations at entry into permanent residential aged care.

BACKGROUND: Entering permanent residential aged care (PRAC) is a vulnerable time for individuals. While falls risk assessment tools exist, these have not leveraged routinely collected and integrated information from the Australian aged and health care sectors. Our study examined individual, system, medication, and health care related factors at PRAC entry that are predictors of fall-related hospitalisations and developed a risk assessment tool using integrated aged and health care data. METHODS: A retrospective cohort study was conducted on N = 32,316 individuals ≥65 years old who entered a PRAC facility (01/01/2009-31/12/2016). Fall-related hospitalisations within 90 or 365 days were the outcomes of interest. Individual, system, medication, and health care-related factors were examined as predictors. Risk prediction models were developed using elastic nets penalised regression and Fine and Gray models. Area under the receiver operating characteristics curve (AUC) assessed model discrimination. RESULTS: 64.2% (N = 20,757) of the cohort were women and the median age was 85 years old (interquartile range 80-89). After PRAC entry, 3.7% (N = 1209) had a fall-related hospitalisation within 90 days and 9.8% (N = 3156) within 365 days. Twenty variables contributed to fall-related hospitalisation prediction within 90 days and the strongest predictors included fracture history (sub-distribution hazard ratio (sHR) = 1.87, 95% confidence interval (CI) 1.63-2.15), falls history (sHR = 1.41, 95%CI 1.21-2.15), and dementia (sHR = 1.39, 95%CI 1.22-1.57). Twenty-seven predictors of fall-related hospitalisation within 365 days were identified, the strongest predictors included dementia (sHR = 1.36, 95%CI 1.24-1.50), history of falls (sHR = 1.30, 95%CI 1.20-1.42) and fractures (sHR = 1.28, 95%CI 1.15-1.41). The risk prediction models had an AUC of 0.71 (95%CI 0.68-0.74) for fall-related hospitalisations within 90 days and 0.64 (95%CI 0.62-0.67) for within 365 days. CONCLUSION: Routinely collected aged and health care data, when integrated at a clear point of action such as entry into PRAC, can identify residents at risk of fall-related hospitalisations, providing an opportunity for better targeting risk mitigation strategies.

Predictors of hospitalisations and emergency department presentations shortly after entering a residential aged care facility in Australia: a retrospective cohort study.

OBJECTIVES: To: (1) examine the 90-day incidence of unplanned hospitalisation and emergency department (ED) presentations after residential aged care facility (RACF) entry, (2) examine individual-related, facility-related, medication-related, system-related and healthcare-related predictors of these outcomes and (3) create individual risk profiles. DESIGN: Retrospective cohort study using the Registry of Senior Australians. Fine-Gray models estimated subdistribution HRs and 95% CIs. Harrell's C-index assessed risk models' predictive ability. SETTING AND PARTICIPANTS: Individuals aged ≥65 years old entering a RACF as permanent residents in three Australian states between 1 January 2013 and 31 December 2016 (N=116 192 individuals in 1967 RACFs). PREDICTORS EXAMINED: Individual-related, facility-related, medication-related, system and healthcare-related predictors ascertained at assessments or within 90 days, 6 months or 1 year prior to RACF entry. OUTCOME MEASURES: 90-day unplanned hospitalisation and ED presentation post-RACF entry. RESULTS: The cohort median age was 85 years old (IQR 80-89), 62% (N=71 861) were women, and 50.5% (N=58 714) had dementia. The 90-day incidence of unplanned hospitalisations was 18.0% (N=20 919) and 22.6% (N=26 242) had ED presentations. There were 34 predictors of unplanned hospitalisations and 34 predictors of ED presentations identified, 27 common to both outcomes and 7 were unique to each. The hospitalisation and ED presentation models out-of-sample Harrell's C-index was 0.664 (95% CI 0.657 to 0.672) and 0.655 (95% CI 0.648 to 0.662), respectively. Some common predictors of high risk of unplanned hospitalisation and ED presentations included: being a man, age, delirium history, higher activity of daily living, behavioural and complex care needs, as well as history, number and recency of healthcare use (including hospital, general practitioners attendances), experience of a high sedative load and several medications. CONCLUSIONS: Within 90 days of RACF entry, 18.0% of individuals had unplanned hospitalisations and 22.6% had ED presentations. Several predictors, including modifiable factors, were identified at the time of care entry. This is an actionable period for targeting individuals at risk of hospitalisations.

Trauma-informed care in geriatric inpatient units to improve staff skills and reduce patient distress: a co-designed study protocol.

BACKGROUND: Geriatric hospital wards are highly medicalised environments with limited opportunities for choice and control, and can be distressing for older survivors of psychological trauma. While trauma-informed models of care (TIC) are effectively applied across mental health and other settings, the utility of these models in aged care settings has not been assessed. The objective of this study was to examine whether TIC can reduce responsive behaviour, chemical restraint, and improve staff skills and patient experiences in inpatient geriatric settings. METHODS: Four wards participated in this type I hybrid implementation-effectiveness study across southern Adelaide, Australia, including 79 beds. Using a co-design method, the principles of TIC were transformed into an implementation strategy including staff training, establishment of highly trained 'champions' on each ward, screening for trauma-related needs, and amending ward policies and procedures. Primary outcomes will be examined using an interrupted time-series design and are monthly incidence of responsive behaviour incidents and use of chemical restraint. Process evaluation will be used to examine secondary, implementation outcomes including the acceptability, feasibility, and fidelity to the implementation strategy. DISCUSSION: Trauma-informed care has potential to improve the safety and accessibility of hospital wards for older people who have survived psychologically traumatic events and has an extensive evidence base supporting its effectiveness in other settings. Identifying trauma-related needs and amending care to reduce the risk of re-traumatisation and distress may also reduce the incidence of responsive behaviour change, which has a significant impact on the quality of life of hospital patients and staff and is very costly. The inclusion of a process evaluation will allow us to identify and report changes made on each ward and make recommendations for future implementation efforts.

Effect of Individual Nutrition Therapy and Exercise Regime on Gait Speed, Physical Function, Strength and Balance, Body Composition, Energy and Protein, in Injured, Vulnerable Elderly: A Multisite Randomized Controlled Trial (INTERACTIVE).

It is imperative that the surgical treatment of hip fractures is followed up with rehabilitation to enhance recovery and quality of life. This randomized controlled trial aimed to determine if an individualised, combined exercise-nutrition intervention significantly improved health outcomes in older adults, after proximal femoral fracture. We commenced the community extended therapy while in hospital, within two weeks post-surgery. The primary outcome was gait speed and secondary outcomes included physical function, strength and balance, body composition, energy and protein intake. Eighty-six and 89 participants were randomized into six months individualised exercise and nutrition intervention and attention-control groups, respectively. There were no statistically significant differences in gait speed between the groups at six and 12 months. There were no major differences between groups with respect to the secondary outcomes, except estimated energy and protein intake. This may be explained by the sample size achieved. Participants in the intervention group had greater increment in energy (235 kcal; 95% CI, 95 to 375; p = 0.01) and protein intake (9.1 g; 95% CI, 1.5 to 16.8; p = 0.02), compared with those in the control group at six months but not significant at 12 months. This study has demonstrated that providing early, combined exercise and nutrition therapy can improve dietary energy and protein intake in older adults with hip fractures.

Prevention of SARS-CoV-2 (COVID-19) transmission in residential aged care using ultraviolet light (PETRA): a two-arm crossover randomised controlled trial protocol.

BACKGROUND: SARS-CoV-2 poses a considerable threat to those living in residential aged care facilities (RACF). RACF COVID-19 outbreaks have been characterised by the rapid spread of infection and high rates of severe disease and associated mortality. Despite a growing body of evidence supporting airborne transmission of SARS-CoV-2, current infection control measures in RACF including hand hygiene, social distancing, and sterilisation of surfaces, focus on contact and droplet transmission. Germicidal ultraviolet (GUV) light has been used widely to prevent airborne pathogen transmission. Our aim is to investigate the efficacy of GUV technology in reducing the risk of SARS-CoV-2 infection in RACF. METHODS: A multicentre, two-arm double-crossover, randomised controlled trial will be conducted to determine the efficacy of GUV devices to reduce respiratory viral transmission in RACF, as an adjunct to existing infection control measures. The study will be conducted in partnership with three aged care providers in metropolitan and regional South Australia. RACF will be separated into paired within-site zones, then randomised to intervention order (GUV or control). The initial 6-week period will be followed by a 2-week washout before crossover to the second 6-week period. After accounting for estimated within-zone and within-facility correlations of infection, and baseline infection rates (10 per 100 person-days), a sample size of n = 8 zones (n = 40 residents/zone) will provide 89% power to detect a 50% reduction in symptomatic infection rate. The primary outcome will be the incidence rate ratio of combined symptomatic respiratory infections for intervention versus control. Secondary outcomes include incidence rates of hospitalisation for complications associated with respiratory infection; respiratory virus detection in facility air and fomite samples; rates of laboratory confirmed respiratory illnesses and genomic characteristics. DISCUSSION: Measures that can be deployed rapidly into RACF, that avoid the requirement for changes in resident and staff behaviour, and that are effective in reducing the risk of airborne SARS-CoV-2 transmission, would provide considerable benefit in safeguarding a highly vulnerable population. In addition, such measures might substantially reduce rates of other respiratory viruses, which contribute considerably to resident morbidity and mortality.

Predictors of short-term hospitalization and emergency department presentations in aged care.

OBJECTIVES: To examine individual, medication, system, and healthcare related predictors of hospitalization and emergency department (ED) presentation within 90 days of entering the aged care sector, and to create risk-profiles associated with these outcomes. DESIGN AND SETTING: Retrospective population-based cohort study using data from the Registry of Senior Australians. PARTICIPANTS: Older people (aged 65 and older) with an aged care eligibility assessment in South Australia between January 1, 2013 and May 31, 2016 (N = 22,130). MEASUREMENTS: Primary outcomes were unplanned hospitalization and ED presentation within 90 days of assessment. Individual, medication, system, and healthcare related predictors of the outcomes at the time of assessment, within 90 days or 1-year prior. Fine-Gray models were used to calculate subdistribution hazard ratios (sHR) and 95% confidence intervals (CI). Harrell's C-index assessed predictive ability. RESULTS: Four thousand nine-hundred and six (22.2%) individuals were hospitalized and 5028 (22.7%) had an ED presentation within 90 days. Predictors of hospitalization included: being a man (hospitalization sHR = 1.33, 95% CI 1.26-1.42), ≥3 urgent after-hours attendances (hospitalization sHR = 1.21, 95% CI 1.06-1.39), increasing frailty index score (hospitalization sHR = 1.19, 95% CI 1.11-1.28), individuals using glucocorticoids (hospitalization sHR = 1.11, 95% CI 1.02-1.20), sulfonamides (hospitalization sHR = 1.18, 95% CI 1.10-1.27), trimethoprim antibiotics (hospitalization sHR = 1.15, 95% CI 1.03-1.29), unplanned hospitalizations 30 days prior (hospitalization sHR = 1.13, 95% CI 1.04-1.23), and ED presentations 1 year prior (hospitalization sHR = 1.07, 95% CI 1.04-1.10). Similar predictors and hazard estimates were also observed for ED presentations. The hospitalization models out-of-sample predictive ability (C-index = 0.653, 95% CI 0.635-0.670) and ED presentations (C-index = 0.647, 95% CI 0.630-0.663) were moderate. CONCLUSIONS: One in five individuals with aged care eligibility assessments had unplanned hospitalizations and/or ED presentation within 90 days with several predictors identified at the time of aged care eligibility assessment. This is an actionable period for targeting at-risk individuals to reduce hospitalizations.
