Measuring the prevalence of 60 health conditions in older Australians in residential aged care with electronic health records: a retrospective dynamic cohort study

Individuals with Cognitive Impairment Entering Long-Term Care: Characteristics and Cumulative Incidence of Dementia after Care Entry

OBJECTIVES

To characterize individuals entering long-term care facilities (LTCFs) with evidence of cognitive impairment and without a diagnosis of dementia, and to ascertain the cumulative incidence of dementia after care entry.

DESIGN

Retrospective cohort study using the Registry of Senior Australians (ROSA) National Historical Cohort.

SETTING AND PARTICIPANTS

Individuals aged 65 to 105 years who entered LTCFs between 2009 and 2018, received a cognitive evaluation, and had no recorded dementia diagnosis at the time of care entry.

METHODS

Cognitive function was determined via the Psychogeriatric Assessment Scales-Cognitive Impairment Scales (PAS-CIS) and defined as none or minimal (PAS-CIS score 0 to <4), mild (4 to <10), or moderate to severe (10 to 21). The cumulative incidence of dementia, determined by aged care assessments, hospitalization, medication, or cause of death, was ascertained for the total cohort and by cognitive impairment status at care entry.

RESULTS

In total, 90,122 individuals [median age 85 years; interquartile range (IQR) 81-89; 64.6% female] were studied, of whom 76.6% (n = 69,075) had cognitive impairment, including 51.4% (n = 46,350) with mild and 25.2% (n = 22,725) with moderate to severe impairment. Over a median follow-up of 1.5 years (IQR 0.6-2.9), the cumulative incidence of dementia was 26.8% [95% confidence interval (CI), 26.5-27.1]. Stratification by cognitive impairment status showed the cumulative incidence of dementia was 17.4% (95% CI, 16.8-17.9) for none or minimal, 27.3% (95% CI, 26.9-27.8) for mild, and 35.3% (95% CI, 34.7-36.0) for moderate to severe.

CONCLUSIONS AND IMPLICATIONS

The cohort of people entering LTCFs with cognitive impairment had a high incidence of dementia diagnosis within 1.5 years after entry. Routine cognitive impairment assessments can inform dementia screening strategies by identifying individuals at higher risk of dementia.

Impact of potentially inappropriate psychotropic medicines on falls among older adults in 23 residential aged care facilities in Australia: a retrospective longitudinal cohort study

OBJECTIVE

Falling is common among older adults in residential aged care facilities (RACFs) and potential inappropriate psychotropic medicines (PIPMs) use may increase the risk of falling. This study aimed to determine the impact of PIPMs on falls using longitudinal observational data.

METHODS

A retrospective longitudinal cohort study was conducted using routinely collected electronic health data from 23 RACFs in Sydney, New South Wales, Australia. The study included 3064 permanent residents aged ≥65 (2020-2021). PIPMs were identified using updated Beers criteria 2023. We considered three fall outcome groups: all falls, injurious falls and falls requiring hospitalisation. The falls incidence rates (IRs) were calculated for overall residents in RACFs as well as for central nervous system (CNS)-PIPM users and non-users. We applied a zero-inflated negative binomial regression model to assess the association between falls and CNS-PIPMs.

RESULTS

A total of 40% (n=1224) of long-term care residents used at least one CNS-PIPM and 10% of residents (n=302) used two or more. The falls IRs of CNS-PIPM users were 16.2 falls per 1000 resident days (95% CI 15.9 to 16.5) for all falls, 5.68 falls per 1000 resident days (95% CI 5.48 to 5.88) for injurious falls and 1.77 falls per 1000 resident days (95% CI 1.66 to 1.88) for falls requiring hospitalisation, whereas the falls IRs of non-CNS-PIPM users were 10.8 falls per 1000 resident days (95% CI 10.6 to 11.0) for all falls, 3.65 falls per 1000 resident days (95% CI 3.52 to 3.78) for injurious falls and 1.26 falls per 1000 resident days (95% CI 1.19 to 1.33) for falls requiring hospitalisation. CNS-PIPM users had a significantly greater rate of falls overall compared with non-users (IRR 1.29; 95% CI 1.16 to 1.44) for all outcomes.

CONCLUSIONS

Falls are frequent among CNS-PIPM users resulting in injury and hospitalisation, with 70% of CNS-PIPM users falling at least once and one in three requiring admissions to hospital. Reviewing residents' use of psychotropic medicines should be considered as part of strategies to reduce falls incidence among older adults in RACFs.

Development of a Predictive Dashboard With Prescriptive Decision Support for Falls Prevention in Residential Aged Care: User-Centered Design Approach

BACKGROUND

Falls are a prevalent and serious health condition among older people in residential aged care facilities, causing significant health and economic burdens. However, the likelihood of future falls can be predicted, and thus, falls can be prevented if appropriate prevention programs are implemented. Current fall prevention programs in residential aged care facilities rely on risk screening tools with suboptimal predictive performance, leading to significant concerns regarding resident safety.

OBJECTIVE

This study aimed to develop a predictive, dynamic dashboard to identify residents at risk of falls with associated decision support. This paper provides an overview of the technical process, including the challenges faced and the strategies used to overcome them during the development of the dashboard.

METHODS

A predictive dashboard was co-designed with a major residential aged care partner in New South Wales, Australia. Data from resident profiles, daily medications, fall incidents, and fall risk assessments were used. A dynamic fall risk prediction model and personalized rule-based fall prevention recommendations were embedded in the dashboard. The data ingestion process into the dashboard was designed to mitigate the impact of underlying data system changes. This approach aims to ensure resilience against alterations in the data systems.

RESULTS

The dashboard was developed using Microsoft Power BI and advanced R programming by linking data silos. It includes dashboard views for those managing facilities and for those caring for residents. Data drill-through functionality was used to navigate through different dashboard views. Resident-level change in daily risk of falling and risk factors and timely evidence-based recommendations were output to prevent falls and enhance prescriptive decision support.

CONCLUSIONS

This study emphasizes the significance of a sustainable dashboard architecture and how to overcome the challenges faced when developing a dashboard amid underlying data system changes. The development process used an iterative dashboard co-design process, ensuring the successful implementation of knowledge into practice. Future research will focus on the implementation and evaluation of the dashboard's impact on health processes and economic outcomes.

Using real-time Delphi methods to develop a consensus-based framework to improve nursing assessment in residential aged care

OBJECTIVES

Evidence-based tools are needed to support aged care nurses in recognising and responding to changes in residents' conditions and clinical deterioration. Systematised emergency nursing frameworks such as HIRAID® (History including Infection risk, Red flags, Assessment, Interventions, Diagnostics, reassessment and communication) assist nurses in accurately assessing and documenting a patient's condition and identifying and prioritising care needs. This study aimed to adapt the HIRAID® emergency nursing framework for use in the residential aged care setting.

METHODS

A real-time Delphi method was employed to contextually adapt the HIRAID® framework. Twelve expert health-care clinical leaders with understanding of patient assessment and residential aged care management were recruited through purposive sampling. Panel consensus was established a priori at 80%. A secondary measure of panel stability was used to understand panel consensus.

RESULTS

Consensus was reached after two survey rounds. In Round 1, 105 (88%) of 119 items were accepted after reaching consensus. In Round 2, all remaining 29 items reached consensus, whereby 20 were accepted and nine rejected. Key modifications were identified for 'History', which needed to consider more comprehensive and adaptive techniques, and 'Interventions' and 'Diagnostics', where differences arose in the scope of practice of aged care nurses compared to their acute care counterparts.

CONCLUSION

The study demonstrated how a small expert multidisciplinary health-care panel can be stable and reach consensus to adapt and contextualise an emergency care framework to the aged care setting. These findings will form the content to scaffold educational resources to support learning and practice change.

Identifying long-term patterns and predictors of concurrent psychotropic medicine use in residential aged care using group-based multi-trajectory modelling: the 'MEDTRAC-Psychotropics' longitudinal cohort study

PURPOSE

Psychotropic medicines are commonly used in residential aged care facilities (RACFs) despite notable safety concerns. No prior studies have examined the longitudinal concurrent use of psychotropic medicines. We aimed to identify trajectories of concurrent use of three psychotropic medication classes over time and determine predictors of trajectory group membership for residents with and without dementia.

METHODS

A retrospective longitudinal cohort study including 30 RACFs in Sydney, Australia. The study participants included 2837 newly admitted permanent residents (n = 1344 with dementia) aged ≥ 65 years. We monitored weekly exposure to three psychotropic classes-antidepressants, antipsychotics, and anxiolytics/hypnotics-over three years. We used group-based multi-trajectory modelling to identify concurrent psychotropic medicine use.

RESULTS

At baseline, 38.5%, 19.6%, and 16.7% of residents with dementia received antidepressants, antipsychotics, and anxiolytics/hypnotics, respectively, compared to 32.8%, 7.1%, and 16.5% in residents without dementia. The concurrent use of multiple psychotropic classes occurred in 23.3% of non-dementia and 31.6% of dementia cohorts. The model identified 6-group and 4-group trajectories as the optimal fit for dementia and non-dementia cohorts, respectively. Psychotropic use trajectories mostly remained stable over time in non-dementia cohorts, while dementia cohorts showed more diverse and fluctuating use. Multinomial logistic regressions identified eleven predictors of trajectory membership in dementia and nine in non-dementia cohorts.

CONCLUSION

One in three residents with dementia and one in five without dementia concurrently use multiple psychotropics often for extended periods, which may put residents at risk. Further research should assess the appropriateness of such use and consider strategies for improving health outcomes.

Use of complementary medicines among older adults living in 23 residential aged care facilities in Australia

BACKGROUND

There is limited information on complementary medicine (CM) use among older adults living in residential aged care facilities (RACFs). This study aimed to determine the prevalence and predictors of CM use and to examine differences in CM use by facility for residents of RACFs.

METHODS

We conducted a retrospective study using routinely collected electronic data about permanent residents aged ≥ 65 years in December 2021 from 23 RACFs in Sydney. The prevalence of CM product use was estimated, and modelling was used to determine factors associated with CM use. Funnel plots visualised differences in prevalence of CM use between facilities.

RESULTS

A total of 1,873 residents were included in the analysis with 78.4% (95% CI: 76.5-80.3) using at least one CM product and 41.2% (95% CI: 39-43.4) using 2 or more CMs. The most frequently used CM products were vitamin D (61.4%), magnesium (18.0%) and calcium (13.1%). Certain diagnoses were associated with both the likelihood of using a CM as well as the number of CMs used. For example, individuals with fractures were more likely to use ≥ 2 CMs (OR 1.29; 95% CI 1.05-1.58), as were those with an endocrine disorder. Residents with circulatory conditions and dementia were less likely to use ≥ 2 CMs. The prevalence of residents using at least one CMs ranged from 54 to 88% between facilities.

CONCLUSIONS

The prevalence of CM use is high in RACFs. Research to investigate the appropriateness of CM use to ensure their safe and effective use in RACFs is needed.

Use of potentially inappropriate psychotropic medicines among older adults in 23 residential aged care facilities in Australia: a retrospective cohort study

BACKGROUND

Psychotropic medications are frequently utilised in residential aged care facilities (RACFs). Longitudinal medication administration data can offer crucial insights into the potential inappropriate use of psychotropic medicines (PIPMs), guiding future quality improvement initiatives. This study aimed to determine the prevalence and predictors of PIPMs use and assess variation in PIPMs use by facility for residents of RACFs.

METHODS

We conducted a retrospective longitudinal cohort study using routinely collected electronic health data (2020-2021) relating to 3064 residents from 23 RACFs in New South Wales, Australia. The study included permanent residents aged ≥ 65 years and median length of stay was 483 days. The prevalence of PIPMs use was estimated using updated Beers criteria 2023. The extent of exposure to PIPMs was measured using two metrics i.e., number of days residents were exposed to PIPMs and the proportion of days covered by PIPMs. We used logistic regression model to determine factors associated with PIPM use. Funnel plots to visualised variation in PIPMs use across facilities.

RESULTS

In total 40% (n = 1224) residents used at least one PIPM and 10% (n = 302) used ≥ 2. The most frequently used PIPMs categories were benzodiazepines and Z-drugs (27.4%), followed by first and second generation antipsychotics (17.2%). Certain diagnoses (dementia, pain, depression, anxiety, and endocrine disorders) were associated with the increased use of PIPMs. For example, residents with dementia were 1.94 times more likely to use ≥ 2 PIPMs (OR 1.94; 95% CI 1.50-2.51). The prevalence of at least one PIPM by residents in each facility ranged from 23.3 to 57.0% across facilities. The overall median number of days residents were exposed to PIPMs were 91 days (IQR 6-320) while the median proportion of days covered by at least one PIPM was 39.3% (IQR 2.6-86.6%).

CONCLUSIONS

Residents in aged care facilities showed a high rate of PIPMs use with substantial variation across facilities. Quality improvement initiatives which target inappropriate psychotropic medication use are necessary, particularly considering the link between psychotropic drug use and adverse events such as falls.

Prevalence of rheumatic and musculoskeletal diseases (RMDs) in nursing home residents: a systematic literature review

PURPOSE

The objective of this systematic literature review was to: (1) estimate the prevalence of (symptoms of) rheumatic and musculoskeletal diseases (RMDs) and (2) explore how (symptoms of) RMDs are identified and documented in studies among nursing home residents.

METHODS

Prevalence data of (symptoms of) RMDs in permanently admitted nursing home residents ≥ 60 years were included. Data extraction, data synthesis and risk of bias assessment were performed by two reviewers independently. Included studies were categorized based on case ascertainment and case definition comprising: (location of) musculoskeletal pain, general terms for RMDs or a specific type of RMD. Results were summarized descriptively.

RESULTS

Out of 6900 records, 53 studies were included. Case ascertainment comprised databases (n = 5), physical examination (n = 1), self-report questionnaires (n = 14), review of medical charts (n = 23) and self-report questionnaires combined with review of medical charts (n = 10). Prevalence ranged between 0.9 and 77.0% for (localized) musculoskeletal pain (n = 19) and between 0.6 and 67.5% for RMDs in general (n = 39). Prevalence rates of specific type of RMDs ranged between 0.7 and 47.5% for gout, between 3.3 and 11.0% for rheumatoid arthritis and between 2.8 and 75.4% for osteo-arthritis (n = 14). Heterogeneity with regard to documentation of (symptoms of) RMDs in medical data of nursing home residents was high.

CONCLUSION

The overall prevalence of (symptoms of) RMDs varied to a great extent. This was mainly due to large heterogeneity in documentation of (symptoms of) RMDs. Establishing agreement on a useful and practical classification may ultimately increase identification of RMDs in the nursing home setting.

Falls in focus: an analysis of the rate of falls in 25 Australian residential aged care facilities from 2019 to 2021, pre- and during COVID-19 lockdowns

INTRODUCTION

During 2020-2021 Australia maintained comparatively low rates of COVID-19 in the community and residential aged care facilities (RAC) due to stringent public health measures such as lockdowns. However, the public health measures implemented may have had unintended impacts on critical RAC resident health outcomes, such as falls, due to routine care disruptions and aged care resident isolation. We utilised a longitudinal data to assess the association between COVID-19 lockdowns and the rate of falls in RAC settings.

METHODS

A longitudinal cohort study was conduct using routinely collected data from 25 RAC facilities from one non-profit aged care provider in Sydney, Australia. The study included 2,996 long term residents between March 2019 and March 2021. The outcome measures were all falls, injurious falls, and falls assessed as requiring hospitalisation. Generalised estimating equations (GEE) were applied to determine the association between COVID-19 lockdown periods and fall-related outcomes while adjusting for confounders and seasonality.

RESULTS

During the study period 11,658 falls were recorded. Residents frequently experienced at least one fall during the study period (median: 1, interquartile range: 0-4). During Lockdown 1 (March-June 2020) the rate of all falls increased 32% (IRR 1.32, 95% CI 1.19-1.46, p < 0.01) and the rate of injurious falls increased by 28% (IRR 1.28, 95% CI 1.12-1.46, p < 0.01) compared to pre-pandemic rates. The rate of falls assessed as requiring hospitalisation remained unchanged during Lockdown 1 (IRR 1.07, 95% CI 0.86-1.32, p = 0.519). During Lockdown 2 (Dec 2020-Jan 2021) the rate of all falls, injurious falls, and falls assessed as requiring hospitalisation did not change significantly compared to pre-pandemic rates.

CONCLUSION

These findings suggest that the consequences of stringent COVID-19 restrictions, as seen in Lockdown 1, produced changes in residents' care which contributed to more falls and associated harm. The subsequent lockdown, which were less restrictive and occurred after staff had gained experience, was associated with no significant increase in falls rate. The nature and extent of lockdowns implemented for infection control in RAC need to balance multiple potential adverse effects. Factors which facilitated resilience during this period require exploration in future research.

Vitamin D supplementation and falls in residential aged care: A longitudinal multisite cohort study

Background

Vitamin D is vital for musculoskeletal health, and supplementation may lower risk of falls. Past research in residential aged care (RAC) settings on the effects of vitamin D on falls have reported inconclusive findings, partly due to study design limitations. We utilised a longitudinal study design to assess the association between the use of vitamin D and falls over 36 months in RAC.

Method

A longitudinal cohort study was conducted using routinely collected electronic data spanning 9 years from 27 RAC facilities in Sydney, New South Wales, Australia. The study included 4520 permanent residents aged 65 years or older who were admitted for the first time from 1 July 2014 and stayed for a minimum of one month. We identified daily vitamin D usage over 36 months, and measured adherence using the Proportion of Days Covered (PDC) metric. A PDC value of ≥80 % signifies optimal adherence. Primary outcomes were the number of all falls and injurious falls. A rolling time-varying predictor-outcome approach and Generalized Estimating Equations (GEE) were applied to determine the longitudinal link between vitamin D supplement use and subsequent risk of falls.

Results

Over two-thirds of residents (67.8 %; n = 3063) received vitamin D supplements during their stay, with a median PDC of 74.8 % among users, and 44.6 % (n = 1365) achieving optimal adherence. Increasing age, osteoporosis or fracture history, and dementia were associated with a greater likelihood of achieving optimal adherence. Crude fall incident rates were 8.05 and 2.92 incidents per 1000 resident days for all falls and injurious falls respectively. After accounting for relevant demographic and clinical factors, no significant links were observed between vitamin D supplement usage and fall outcomes: all falls (Incident Rate Ratio [IRR] 1.01; 95 % CI 1.00-1.02; P = 0.237) and injurious falls (IRR 1.01; 95 % CI 1.00-1.02; P = 0.091).

Conclusion

Vitamin D supplementation was not associated with a reduced risk of falls, suggesting it is not an effective intervention for preventing falls in RAC. While clinicians should ensure adequate vitamin D intake for residents' nutritional and bone health, it should not be a standalone falls prevention intervention in RAC populations.

The matter of grief, loss and bereavement in families of those living and dying in residential aged care setting: A systematic review

The grief, loss and bereavement needs of the families of those living and dying in residential aged care setting is not very well understood. This systematic review examines grief, loss, and bereavement experience of, and interventions relating to, family caregivers of those entering, living and dying in residential aged care. Out of 2023 papers that were identified, 35 met the inclusion criteria which included (n=28) qualitative and (n=7) quantitative intervention studies. The qualitative findings indicated quality of care provided to the resident at the end of their life, and after death care influenced family caregivers' grief reactions. The intervention studies revealed that educational interventions have the potential to lead to some benefits in the context of grief loss and bereavement outcomes. Recognizing the emotional experiences and support needs of families and carers may enhance the understanding of the ageing, caring, dying, grieving pathway for older people and their families.

Simplifying medication regimens for residents of aged care facilities: Pharmacist and physician use of a structured five-step medication simplification tool

BACKGROUND

Pharmacist-led medication regimen simplification using a structured approach can reduce unnecessary medication regimen complexity in residential aged care facilities (RACFs), but no studies have investigated simplification by different health professionals, nor the extent to which simplification is recommended during comprehensive medication reviews.

OBJECTIVES

To compare medication regimen simplification opportunities identified by pharmacists, general medical practitioners (GPs), and geriatricians and to determine if pharmacists identified simplification opportunities during routinely conducted comprehensive medication reviews in RACFs for these same residents.

METHODS

Three pharmacists, three GPs and three geriatricians independently applied the Medication Regimen Simplification Guide for Residential Aged CarE (MRS GRACE) to medication data for 83 residents taking medications at least twice daily. Interrater agreement was calculated using Fleiss's kappa. Pharmacist medication review reports for the same 83 residents were then examined to identify if the pharmacists conducting these reviews had recommended any of the simplification strategies.

RESULTS

Overall, 77 residents (92.8 %) taking medications at least twice daily could have their medication regimen simplified by at least one health professional. Pharmacists independently simplified 53.0-77.1 % of medication regimens (Κ = 0.60, 95%CI 0.46-0.75, indicating substantial agreement), while GPs simplified 74.7-89.2 % (Κ = 0.44, 95%CI 0.24-0.64, moderate agreement) and geriatricians simplified 41.0-66.3 % (Κ = 0.30, 95%CI 0.16-0.44, fair agreement). No simplification recommendations were included in the reports previously prepared by pharmacists as part of the comprehensive medication reviews undertaken for these residents.

CONCLUSION

Pharmacists, GPs, and geriatricians can all identify medication regimen simplification opportunities, although these opportunities differ within and between professional groups. Although opportunities to simplify medication regimens during comprehensive medication reviews exist, simplification is not currently routinely recommended by pharmacists performing these reviews in Australian RACFs.

Applying generative AI with retrieval augmented generation to summarize and extract key clinical information from electronic health records

BACKGROUND

Malnutrition is a prevalent issue in aged care facilities (RACFs), leading to adverse health outcomes. The ability to efficiently extract key clinical information from a large volume of data in electronic health records (EHR) can improve understanding about the extent of the problem and developing effective interventions. This research aimed to test the efficacy of zero-shot prompt engineering applied to generative artificial intelligence (AI) models on their own and in combination with retrieval augmented generation (RAG), for the automating tasks of summarizing both structured and unstructured data in EHR and extracting important malnutrition information.

METHODOLOGY

We utilized Llama 2 13B model with zero-shot prompting. The dataset comprises unstructured and structured EHRs related to malnutrition management in 40 Australian RACFs. We employed zero-shot learning to the model alone first, then combined it with RAG to accomplish two tasks: generate structured summaries about the nutritional status of a client and extract key information about malnutrition risk factors. We utilized 25 notes in the first task and 1,399 in the second task. We evaluated the model's output of each task manually against a gold standard dataset.

RESULT

The evaluation outcomes indicated that zero-shot learning applied to generative AI model is highly effective in summarizing and extracting information about nutritional status of RACFs' clients. The generated summaries provided concise and accurate representation of the original data with an overall accuracy of 93.25%. The addition of RAG improved the summarization process, leading to a 6% increase and achieving an accuracy of 99.25%. The model also proved its capability in extracting risk factors with an accuracy of 90%. However, adding RAG did not further improve accuracy in this task. Overall, the model has shown a robust performance when information was explicitly stated in the notes; however, it could encounter hallucination limitations, particularly when details were not explicitly provided.

CONCLUSION

This study demonstrates the high performance and limitations of applying zero-shot learning to generative AI models to automatic generation of structured summarization of EHRs data and extracting key clinical information. The inclusion of the RAG approach improved the model performance and mitigated the hallucination problem.

Retrospective observational study of aged care facility residents presenting to ED post fall: A case for person-centred shared decision making

OBJECTIVE

Identify the incidence of intracranial haemorrhage in people from residential aged care facilities following falls who had a CT head performed. The secondary objectives were to identify predictor variables for intracranial haemorrhage to inform person-centred shared decision making.

METHODS

Retrospective chart review of aged care residents who presented to ED with a triage of fall. Documented evidence of vomiting, headache, external signs of head injury, deviation from baseline neurology and the presence of anticoagulation or antiplatelet agents was reviewed. The rates of CT head, intracranial haemorrhage, emergent interventions, disposition and mortality were assessed.

RESULTS

Of the 2546 presentations, 1732 (68.0%) had a CT head and intracranial haemorrhage was found in 76 (4.4%) patients. External signs of head injury and deviation from neurological baseline have a strong association with intracranial haemorrhage in 26 (22.2%) patients, only 4 (0.61%) patients with intracranial haemorrhage had neither. There was a strong association between these clinical features and identification of intracranial haemorrhage on CT head. Anticoagulation and antiplatelet use had no association with intracranial haemorrhage. A 30-day mortality was increased in patients with deviation from neurological baseline. No neurosurgical intervention was performed, and there was inconsistent advice regarding anticoagulation or antiplatelet agents.

CONCLUSIONS

Deviation from neurological baseline or external signs of head injury may be predictors of intracranial haemorrhage. Vomiting, headache, anticoagulation or antiplatelets were not associated with intracranial haemorrhage. A person-centred decision-making approach, that is informed by treatment options could better guide clinicians on when to order a CT head after a fall.

Telemedicine vs Face-to-Face for Nursing Home Residents With Acute Presentations: A Noninferiority Study

OBJECTIVES

Telemedicine and face-to-face outreach services to nursing homes (NHs) have been used to reduce hospital utilization rates for acute presentations. However, how these modalities compare against each other is unclear. This article examines if the management of acute presentations in NHs with care involving telemedicine is noninferior to care delivered face-to-face.

DESIGN

A noninferiority study was conducted on a prospective cohort. Face-to-face intervention involved on-site assessment by a geriatrician and aged care clinical nurse specialist (CNS). Telemedicine intervention involved on-site assessment by an aged care CNS with telemedicine input by a geriatrician.

SETTING AND PARTICIPANTS

A total of 438 NH residents with acute presentations from 17 NHs between November 2021 and June 2022.

METHODS

Between-group differences in proportion of residents successfully managed on-site and mean number of encounters were evaluated using bootstrapped multiple linear regression; 95% CIs were compared against predefined noninferiority margins with noninferiority P values calculated.

RESULTS

In the adjusted models, care involving telemedicine demonstrated noninferiority in the difference in proportion of residents successfully managed on-site (95% CI lower limit -6.2% to -1.4% vs -10% noninferiority margin; P < .001 for noninferiority) but not in the difference in mean number of encounters (95% CI upper limit 1.42 to 1.50 encounters vs 1 encounter noninferiority margin; P = .7 for noninferiority).

CONCLUSIONS AND IMPLICATIONS

In our model of care, care that involved telemedicine was noninferior to care delivered face-to-face in managing NH residents with acute presentations on-site. However, additional encounters may be required. Application of telemedicine ought to be tailored to fit the needs and preferences of stakeholders.

Study protocol for ELders AT Ease (ELATE): a cluster randomised controlled trial of cognitive behaviour therapy to reduce depressive symptoms in aged care residents

BACKGROUND

This protocol describes a study of the effectiveness of cognitive behaviour therapy (CBT) for reducing depressive symptoms in older adults living in residential aged care (RAC) facilities in Australia. Depressive symptoms are highly prevalent in this population, yet the benefits of CBT for reducing such symptoms in RAC facilities have not been widely investigated. Elders at Ease (ELATE) is a 16-session CBT intervention designed for implementation in RAC facilities. The intervention includes cognitive, behavioural and reminiscence strategies and is delivered by mental health trainees (MHTs) in collaboration with RAC facility staff and residents' family.

METHODS AND ANALYSIS

ELATE will be evaluated using a cluster randomised trial comparing outcomes for residents who participate in the intervention with those living in usual care control facilities. The participants are RAC residents aged 65 years or above, with depressive symptoms (Patient Health Questionnaire-2 ≥ 3) and normal cognition or mild cognitive impairment (Standardised Mini Mental Status Examination ≥ 21). They are assessed at four time points: baseline prior to randomisation (T1), mid-treatment (T2; 2.5 months post randomisation), post-treatment (T3; 5 months post-randomisation) and 3-month follow-up (T4; 8 months post randomisation). The primary outcome is change in depressive symptoms between T1 and T3. Secondary outcomes are depressive symptoms at T4, anxiety, suicide ideation, sleep problems, quality of life, staff and family knowledge of late-life depression, stress levels and efficacy in caring for residents, and MHT levels of geropsychology competencies. Residents receiving the intervention are hypothesised to report a greater decrease in depressive symptoms between T1 and T3 compared to residents receiving usual care. The primary analysis is a regression, clustered over site to account for correlated readings, and independent variables are condition and depressive symptoms at T1. A cost-utility analysis is also undertaken.

DISCUSSION

ELATE is a comprehensive CBT intervention for reducing depressive symptoms in RAC residents. It is designed to be implemented in collaboration with facility staff and residents' families, individually tailored to residents with normal cognition to mild cognitive impairment and delivered by trainee therapists. ELATE offers a model that may be widely applicable across the RAC sector.

What can death records tell us about multimorbidity?

BACKGROUND

Multimorbidity has been measured from many data sources which show that prevalence increases with age and is usually greater among women than men and in more recent periods. Analyses of multiple cause of death data have shown different patterns of multimorbidity associated with demographic and other characteristics.

METHODS

Deaths in Australia among over 1.7 million decedents aged 55+ were stratified into three types: medically certified deaths, coroner-referred deaths with natural underlying causes and coroner-referred deaths with external underlying causes. Multimorbidity was measured by prevalence of ≥2 causes and analysed over three periods based on administrative changes: 2006-2012, 2013-2016 and 2017-2018. Poisson regression was used to examine the influence of gender, age and period.

RESULTS

The prevalence of deaths with multimorbidity was 81.0% for medically certified deaths, 61.1% for coroner-referred deaths with natural underlying causes and 82.4% for coroner-referred deaths with external underlying causes. For medically certified deaths, multimorbidity increased with age: incidence rate ratio (IRR 1.070, 95% CI 1.068, 1.072) was lower for women than men (0.954, 95% CI 0.952, 0.956) and changed little over time. For coroner-referred deaths with natural underlying causes, multimorbidity showed the expected pattern increasing with age (1.066, 95% CI 1.062, 1.070) and being higher for women than men (1.025, 95% CI 1.015, 1.035) and in more recent periods. For coroner-referred deaths with external underlying causes, there were marked increases over time that differed by age group due to changes in coding processes.

CONCLUSION

Death records can be used to examine multimorbidity in national populations but, like other data sources, how the data were collected and coded impacts the conclusions.

Malnutrition and its contributing factors for older people living in residential aged care facilities: Insights from natural language processing of aged care records

BACKGROUND

Malnutrition is a serious health risk facing older people living in residential aged care facilities. Aged care staff record observations and concerns about older people in electronic health records (EHR), including free-text progress notes. These insights are yet to be unleashed.

OBJECTIVE

This study explored the risk factors for malnutrition in structured and unstructured electronic health data.

METHODS

Data of weight loss and malnutrition were extracted from the de-identified EHR records of a large aged care organization in Australia. A literature review was conducted to identify causative factors for malnutrition. Natural language processing (NLP) techniques were applied to progress notes to extract these causative factors. The NLP performance was evaluated by the parameters of sensitivity, specificity and F1-Score.

RESULTS

The NLP methods were highly accurate in extracting the key data, values for 46 causative variables, from the free-text client progress notes. Thirty three percent (1,469 out of 4,405) of the clients were malnourished. The structured, tabulated data only recorded 48% of these malnourished clients, far less than that (82%) identified from the progress notes, suggesting the importance of using NLP technology to uncover the information from nursing notes to fully understand the health status of the vulnerable older people in residential aged care.

CONCLUSION

This study identified 33% of older people suffered from malnutrition, lower than those reported in the similar setting in previous studies. Our study demonstrates that NLP technology is important for uncovering the key information about health risks for older people in residential aged care. Future research can apply NLP to predict other health risks for older people in this setting.

Measuring quality of gout management in residential aged care facilities

OBJECTIVE

Gout, a common form of arthritis, can be controlled successfully with pharmacotherapy and is thus an ideal model for examining chronic disease management. Our aim was to examine treatment of gout evaluated in accordance with general management guidelines for gout as applied to Australian residential aged care facilities.

METHODS

Electronic health record data linked with aged care clinical notes and electronic medication administration information (11 548 residents in 68 residential aged care facilities, >65 years of age) were interrogated to identify people with gout, other chronic conditions and gout medication use. The outcomes examined were the proportion receiving urate-lowering therapy (ULT; preventative medication) and/or colchicine/non-steroidal anti-inflammatory drug (NSAID) (to treat gout flares), the number of ULT and colchicine/NSAID treatment episodes (periods of continuous days of medication use) and the duration of these treatment episodes.

RESULTS

The cohort included 1179 residents with gout, of whom 62% used a ULT, with a median of one episode of use for a very short duration [median = 4 days, median of use in total (i.e. repeated use) = 52 days]. Among residents with gout, 9% also used colchicine or an NSAID. Female residents were less likely to receive ULT and for shorter periods.

CONCLUSION

Nearly one-third of residents with gout did not receive ULT. In those receiving ULT, recurrent short courses were common. Overall, management of gout in aged care residents appears to be suboptimal, largely owing to intermittent and short exposure to ULT, and with female residents at greater risk of poor gout management.

'You've Got No Support': The Experiences of Older Male Caregivers When Their Partner Enters Residential Care

This qualitative phenomenological study explored the experiences and needs of eight older male caregivers after their partner entered full-time residential aged care within the past 36 months. Semi-structured interviews were conducted, thematically analyzed, and member-checked for accuracy. This transition was a time of significant turmoil for caregivers. Feelings of grief, loss, guilt, and regret were experienced, intertwined with feelings of relief and reassurance that their partner would be well cared for within the care facility. Following the transition, caregivers also began thinking about building a new life. Helpful supports identified were friends and family, carer support groups, counseling services, and community support organizations. Participants described a need for further emotional support, assistance in understanding their partner's prognosis, and information about the expenses involved in entering residential care. It was suggested there is also a role for professional advisors or peer mentors to support male caregivers through this transition. Tailoring programs and services with consideration of the needs and experiences of older male caregivers will ensure that policies and programs are more supportive and responsive.

Multimorbidity Patterns and 5-Year Mortality in Institutionalized Older Adults

OBJECTIVES

The aim was to characterize multimorbidity patterns in a large sample of older individuals living in nursing homes (NHs) and to investigate their association with mortality, also considering the effect of functional status.

DESIGN

Observational and retrospective study.

SETTING AND PARTICIPANTS

We analyzed data on 4131 NH residents in Italy, aged 60 years and older, assessed through the interRAI long-term care facility instrument. Entry date was between 2014 and 2018, and participants were followed until 2019.

METHODS

Multimorbidity patterns were identified through principal component analysis; for the identified components, subjects were stratified in quintiles (Q) with respect to their loading values, with the higher quantiles indicating greater expression of the component's pattern. Their association [hazard ratio (HR) and 95% CI] with mortality was tested in Cox regression models. Analyses were stratified by disability status.

RESULTS

Four patterns of multimorbidity were identified: (1) heart diseases; (2) dementia and sensory impairments; (3) heart, respiratory, and psychiatric diseases; and (4) diabetes, musculoskeletal, and vascular diseases. For the heart diseases pattern [HR Q5 vs Q1 = 1.83 (1.53-2.20)] and the dementia and sensory impairments pattern [HR Q5 vs Q1 = 1.23 (1.06-1.42)], as the specific multimorbidity expression increases, the risk of mortality increases. On stratifying by disability status, the association between the multimorbidity patterns and mortality was not always present.

CONCLUSIONS AND IMPLICATIONS

Different multimorbidity patterns are differentially associated with mortality in older residents of NHs, confirming that multimorbidity's prognosis is strictly dependent on the underlying disease combinations. This knowledge may be useful to implement personalized preventive and therapeutic care pathways for institutionalized older adults, which respond to individuals' health needs.

Supporting residential aged care through a Community of Practice

Transfers to Emergency Departments and hospitalizations are common for older people living in residential aged care who experience acute deterioration. This paper shares reflections from 10 years of work across a region in New South Wales, Australia, to develop a new model of care in141 residential aged care homes. The model successfully reduced Emergency Department transfers and admissions to hospital. Using an exemplar patient case, the paper describes the Aged Care Emergency Program and associated research outputs. An interprofessional, multi-agency Community of Practice supported this work. The authors reflect on the successes and challenges of using a Community of Practice to implement the model of care. We conclude that the Community of Practice, with its iterative evaluation, facilitated change and provided a mechanism for interprofessional practice. Broader systemic change requires clarity in goals of care, shared decision-making, working across sectors, and appropriate resource allocation. This article is protected by copyright.

Caring self-efficacy of direct care workers in residential aged care settings: A mixed methods scoping review

The caring self-efficacy of direct care workers in residential aged care has been explored in the literature mostly as a predictor rather than the focus of interest. This scoping review aimed to provide an overview of the existing literature on aged care workers' caring self-efficacy and factors that influence it. A systematic search was performed in six electronic databases. All primary studies were included. A total of 41 studies met the inclusion criteria. Caring self-efficacy was most often described by aged care workers as their capacity to deal with difficult situations. The self-efficacy scores of direct care workers were high across studies. Self-efficacy was positively influenced by access to resources, relationships with residents and their families, the support of supervisors and co-workers, job satisfaction, and training opportunities, and negatively affected by work pressure and burnout. Findings indicate possible avenues for intervention to improve direct care workers' self-efficacy in aged care.

Regulation of Long-Term Care Homes for Older Adults in India

The rising aging population in India has led to an increased caregiving burden, and accordingly, the number of residential care facilities is also burgeoning. There is no regulatory framework or registration authority specifically for residential care homes in India. The article's objective is to understand the need for a regulatory framework in India in the context of historic and global experiences in the UK, USA, and Europe. Although there is a lack of literature comparing the community home-based care and residential care, one study reported a preference for home-based care in the South Asian context. Elder abuse and deprivation of rights of seniors are common, and there is a need to bring in more safeguards to prevent these from the perspective of the older adults, their family members, the care providers, and the state. While the main priority of meeting care needs in long-term care is a challenge given the lack of trained care staff, the quality control mechanisms also need to evolve. A review of adverse incidents, complaints, and litigations also highlights the need for regulation to improve the standards and quality of care. The article explores lacunae of residential care facilities in the Indian context and provides recommendatory parameters for evaluating the quality of care provided. Relevant sections of the statutory new Mental Healthcare Act of 2017 in India could provide a regulatory framework ensuring rights and liberties of the residents are upheld. The authors propose a state-run model for elderly care homes and commencement of framing regulations appropriate to the Indian context.

Increased number of deaths within 24 h of admission during a period of social restriction related to the COVID-19 pandemic: A retrospective service evaluation in a metropolitan palliative care unit

BACKGROUND

COVID-19 has led to implementation of wide-ranging social restriction measures with consequent impact on health care utilisation in many domains. There is little published data on the experience of palliative care services catering to a population with low case numbers of COVID-19.

AIM

This study aimed to consider the impact of COVID-19 on utilisation of inpatient palliative care in the context of low community transmission, and low numbers of cases in hospital.

DESIGN

A retrospective service evaluation examining differences in number of admissions, diagnoses, number of deaths and time from admission to death, across three discrete 8-week time periods spanning the early COVID-19 pandemic.

SETTING/PARTICIPANTS

All admissions (n = 194) to a metropolitan tertiary hospital inpatient palliative care unit in Melbourne during the study period.

RESULTS

An initial 16.9% fall in admissions was followed by a return to baseline admission numbers, with a 46.7% increase in number of deaths compared to baseline. The number of deaths within 24 h rose from 10.8% to 37.3% (p < 0.01). The number of patients with non-malignant diagnoses increased from 32.4% to 52%, and those with non-malignant diagnoses were more likely to die rapidly (p < 0.01). There were no patients with COVID-19 infection.

CONCLUSION

Increased numbers of deaths within 24 h of admission occurred on the palliative care unit despite low COVID-19 case numbers in the wider community, and in the setting of widespread social restriction measures. More research is needed examining the health-related consequences of such restrictions for individuals not infected with COVID-19.

Co-designing a dashboard of predictive analytics and decision support to drive care quality and client outcomes in aged care: a mixed-method study protocol

INTRODUCTION

There is a clear need for improved care quality and quality monitoring in aged care. Aged care providers collect an abundance of data, yet rarely are these data integrated and transformed in real-time into actionable information to support evidence-based care, nor are they shared with older people and informal caregivers. This protocol describes the co-design and testing of a dashboard in residential aged care facilities (nursing or care homes) and community-based aged care settings (formal care provided at home or in the community). The dashboard will comprise integrated data to provide an 'at-a-glance' overview of aged care clients, indicators to identify clients at risk of fall-related hospitalisations and poor quality of life, and evidence-based decision support to minimise these risks. Longer term plans for dashboard implementation and evaluation are also outlined.

METHODS

This mixed-method study will involve (1) co-designing dashboard features with aged care staff, clients, informal caregivers and general practitioners (GPs), (2) integrating aged care data silos and developing risk models, and (3) testing dashboard prototypes with users. The dashboard features will be informed by direct observations of routine work, interviews, focus groups and co-design groups with users, and a community forum. Multivariable discrete time survival models will be used to develop risk indicators, using predictors from linked historical aged care and hospital data. Dashboard prototype testing will comprise interviews, focus groups and walk-through scenarios using a think-aloud approach with staff members, clients and informal caregivers, and a GP workshop.

ETHICS AND DISSEMINATION

This study has received ethical approval from the New South Wales (NSW) Population & Health Services Research Ethics Committee and Macquarie University's Human Research Ethics Committee. The research findings will be presented to the aged care provider who will share results with staff members, clients, residents and informal caregivers. Findings will be disseminated as peer-reviewed journal articles, policy briefs and conference presentations.

Transforming routinely collected residential aged care provider data into timely information: Current and future directions

Electronic information systems are becoming increasingly common in residential aged care in Australia. These systems contain valuable data generated during day-to-day care delivery for older adults. These data (termed 'routinely collected residential aged care provider data') are currently underutilised, however have potential significant benefits for both care delivery and research purposes. Routinely collected residential aged care provider data are more readily accessible, contain up-to-date information and can be linked to existing national or state-based administrative data sets, while providing more granular details about care delivered at the coalface. The aim of this paper is to provide clinicians, researchers, policymakers and providers with an understanding of the strengths of these types of data, as well as identifying areas that require future development to maximise their potential to drive improvements in resident care and outcomes. These considerations include data quality, data standardisation and models for data governance, consent and consumer involvement.

The Frailty In Residential Sector over Time (FIRST) study: methods and baseline cohort description

BACKGROUND

The Frailty In Residential Sector over Time (FIRST) Study is a 3-year prospective cohort study investigating the health of residents living in residential aged care services (RACS) in South Australia. The study aims to examine the change in frailty status and associated health outcomes.

METHODS

This interim report presents data from March 2019-October 2020. The study setting is 12 RACS from one organisation across metropolitan and rural South Australia involving 1243 residents. All permanent (i.e. respite or transition care program excluded) residents living in the RACS for at least 8 weeks were invited to participate. Residents who were deemed to be medically unstable (e.g. experiencing delirium), have less than 3 months to live, or not fluent in English were excluded. Data collected included frailty status, medical diagnoses, medicines, pain, nutrition, sarcopenia, falls, dementia, anxiety and depression, sleep quality, quality of life, satisfaction with care, activities of daily living, and life space use at baseline and 12-months. Data Linkage will occur over the 3 years from baseline.

RESULTS

A total of 561 permanent residents (mean age 87.69 ± 7.25) were included. The majority of residents were female (n = 411, 73.3%) with 95.3% (n = 527) being classified as either frail (n = 377, 68.2%) or most-frail (n = 150, 27.1%) according to the Frailty Index (FI). Most residents were severely impaired in their basic activities of daily living (n = 554, 98.8%), and were at-risk of malnutrition (n = 305, 55.0%) and at-risk of sarcopenia (n = 492, 89.5%). Most residents did not experience pain (n = 475, 85.4%), had normal daytime sleepiness (n = 385, 69.7%), and low anxiety and depression scores (n = 327, 58.9%).

CONCLUSION

This study provides valuable information on the health and frailty levels of residents living in RACS in South Australia. The results will assist in developing interventions that can help to improve the health and wellbeing of residents in aged care services.

Trends, determinants and differences in antibiotic use in 68 residential aged care homes in Australia, 2014-2017: a longitudinal analysis of electronic health record data

BACKGROUND

Internationally, point prevalence surveys are the main source of antibiotic use data in residential aged care (RAC). Our objective was to describe temporal trends in antibiotic use and antibiotics flagged for restricted use, resident characteristics associated with use, and variation in use by RAC home, using electronic health record data.

METHODS

We conducted a retrospective cohort study of 9793 unique residents aged ≥65 years in 68 RAC homes between September 2014 and September 2017, using electronic health records. We modelled the primary outcome of days of antibiotic therapy /1000 resident days (DOT/1000 days), and secondary outcomes of number of courses/1000 days and the annual prevalence of antibiotic use. Antibiotic use was examined for all antibiotics and antibiotics on the World Health Organization's (WHO) Watch List (i.e. antibiotics flagged for restricted use).

RESULTS

In 2017, there were 85 DOT/1000 days (99% CI: 79, 92), 8.0 courses/1000 days (99% CI: 7.6, 8.5), and 63.4% (99% CI: 61.9, 65.0) of residents received at least one course of antibiotics. There were 7.7 DOT/1000 days (99% CI: 6.69, 8.77) of antibiotics on the WHO Watch List administered in 2017. Antibiotic use increased annually by 4.09 DOT/1000 days (99% CI: 1.18, 6.99) before adjusting for resident factors, and 3.12 DOT/1000 days (99% CI: - 0.05, 6.29) after adjustment. Annual prevalence of antibiotic use decreased from 68.4% (99% CI: 66.9, 69.9) in 2015 to 63.4% (99% CI: 61.9, 65.0) in 2017, suggesting fewer residents were on antibiotics, but using them for longer. Resident factors associated with higher use were increasing age; chronic respiratory disease; a history of urinary tract infections, and skin and soft tissue infections; but dementia was associated with lower use. RAC home level antibiotic use ranged between 44.0 to 169.2 DOT/1000 days in 2016. Adjusting for resident factors marginally reduced this range (42.6 to 155.5 DOT/1000 days).

CONCLUSIONS

Antibiotic course length and RAC homes with high use should be a focus of antimicrobial stewardship interventions. Practices in RAC homes with low use could inform interventions and warrant further investigation. This study provides a model for using electronic health records as a data source for antibiotic use surveillance in RAC.
