The effectiveness and cost effectiveness of a hospital avoidance program in a residential aged care facility: a prospective cohort study and modelled decision analysis

From pilot to a multi-site trial: refining the Early Detection of Deterioration in Elderly Residents (EDDIE +) intervention

BACKGROUND

Early Detection of Deterioration in Elderly Residents (EDDIE +) is a multi-modal intervention focused on empowering nursing and personal care workers to identify and proactively manage deterioration of residents living in residential aged care (RAC) homes. Building on successful pilot trials conducted between 2014 and 2017, the intervention was refined for implementation in a stepped-wedge cluster randomised trial in 12 RAC homes from March 2021 to May 2022. We report the process used to transition from a small-scale pilot intervention to a multi-site intervention, detailing the intervention to enable future replication.

METHODS

The EDDIE + intervention used the integrated Promoting Action on Research Implementation in Health Services (i-PARIHS) framework to guide the intervention development and refinement process. We conducted an environmental scan; multi-level context assessments; convened an intervention working group (IWG) to develop the program logic, conducted a sustainability assessment and deconstructed the intervention components into fixed and adaptable elements; and subsequently refined the intervention for trial.

RESULTS

The original EDDIE pilot intervention included four components: nurse and personal care worker education; decision support tools; diagnostic equipment; and facilitation and clinical support. Deconstructing the intervention into core components and what could be flexibly tailored to context was essential for refining the intervention and informing future implementation across multiple sites. Intervention elements considered unsustainable were updated and refined to enable their scalability. Refinements included: an enhanced educational component with a greater focus on personal care workers and interactive learning; decision support tools that were based on updated evidence; equipment that aligned with recipient needs and available organisational support; and updated facilitation model with local and external facilitation.

CONCLUSION

By using the i-PARIHS framework in the scale-up process, the EDDIE + intervention was tailored to fit the needs of intended recipients and contexts, enabling flexibility for local adaptation. The process of transitioning from a pilot to larger scale implementation in practice is vastly underreported yet vital for better development and implementation of multi-component interventions across multiple sites. We provide an example using an implementation framework and show it can be advantageous to researchers and health practitioners from pilot stage to refinement, through to larger scale implementation.

Emergency department admissions and economic costs burden related to ambulatory care sensitive conditions in older adults living in care homes

OBJECTIVES

To assess the frequency of emergency department admissions (EDA) for ambulatory care sensitive conditions (ACSC) and non-ACSC among older adults living in care homes (CH), to describe and compare their demographic and clinical characteristics, the outcomes of the hospitalisation process and the associated costs.

METHOD

This multicenter, retrospective and observational study evaluated 2444 EDAs of older adults ≥ 65 years old living in care homes in 5 emergency departments in Catalonia (Spain) by ACSC and non-ACSC, in 2017. Sociodemographic variables, prior functional and cognitive status, and information on diagnosis and hospitalisation were collected. Additionally, the costs related with the EDAs were calculated, as well as a sensitivity analysis using different assumptions of decreased admissions due to ACSC.

RESULTS

A total of 2444 ED admissions were analysed. The patients' mean (SD) age was 85.9 (7.2) years. The frequency of ACSC-EDA and non-ACSC-EDA was 56.6% and 43.4%, respectively. Severe dependency and cognitive impairment were present in 56.6% and 78%, respectively, with no differences between the two groups. The three most frequent ACSC were falls/trauma (13.8%), chronic obstructive pulmonary disease/asthma (11.4%) and urinary tract infection (7.4%). The average cost per ACSC-EDA was є1,408.24. Assuming a 60% reduction of ACSC-EDA, the estimated cost savings would be є1.2 million.

CONCLUSIONS

Emergency admissions for ACSC from care homes have a significant impact on both frequency and costs. Reducing these conditions through targeted interventions could redirect the avoided costs towards improving care support in residential settings.

Cost-benefit analysis of the CoCare intervention to improve medical care in long-term care nursing homes: an analysis based on claims data

BACKGROUND

Providing adequate medical care to nursing home residents is challenging. Transfers to emergency departments are frequent, although often avoidable. We conducted the complex CoCare intervention with the aim to optimize nursing staff-physician collaboration to reduce avoidable hospital admissions and ambulance transportations, thereby reducing costs.

METHODS

This prospective, non-randomized study, based on German insurance data, includes residents in nursing homes. Health care cost from a payer perspective and cost-savings of such a complex intervention were investigated. The utilisation of services after implementation of the intervention was compared with services in previous quarters as well as services in the control group. To compensate for remaining differences in resident characteristics between intervention and control group, a propensity score was determined and adjusted for in the regression analyses.

RESULTS

The study population included 1240 residents in the intervention and 7552 in the control group. Total costs of medical services utilisation were reduced by €468.56 (p < 0.001) per resident and quarter in the intervention group. Hospital stays were reduced by 0.08 (p = 0.001) and patient transports by 0.19 (p = 0.049). This led to 1.66 (p < 0.001) avoided hospital days or €621.37 (p < 0.001) in costs-savings of inpatient services. More services were billed by general practitioners in the intervention group, which led to additional costs of €97.89 (p < 0.001).

CONCLUSION

The benefits of our intervention clearly exceed its costs. In the intervention group, avoided hospital admissions led to additional outpatient billing. This indicates that such a multifactorial intervention program can be cost-saving and improve medical care in long-term care homes.

Reducing unplanned hospital admissions from care homes: a systematic review

Background

Care homes predominantly care for older people with complex health and care needs, who are at high risk of unplanned hospital admissions. While often necessary, such admissions can be distressing and provide an opportunity cost as well as a financial cost.

Objectives

Our objective was to update a 2014 evidence review of interventions to reduce unplanned admissions of care home residents. We carried out a systematic review of interventions used in the UK and other high-income countries by synthesising evidence of effects of these interventions on hospital admissions; feasibility and acceptability; costs and value for money; and factors affecting applicability of international evidence to UK settings.

Data sources

We searched the following databases in December 2021 for studies published since 2014: Cochrane Central Register of Controlled Trials and Cochrane Database of Systematic Reviews; Cumulative Index to Nursing and Allied Health Literature; Health Management Information Consortium; Medline; PsycINFO; Science and Social Sciences Citation Indexes; Social Care Online; and Social Service Abstracts. 'Grey' literature (January 2022) and citations were searched and reference lists were checked.

Methods

We included studies of any design reporting interventions delivered in care homes (with or without nursing) or hospitals to reduce unplanned hospital admissions. A taxonomy of interventions was developed from an initial scoping search. Outcomes of interest included measures of effect on unplanned admissions among care home residents; barriers/facilitators to implementation in a UK setting and acceptability to care home residents, their families and staff. Study selection, data extraction and risk of bias assessment were performed by two independent reviewers. We used published frameworks to extract data on intervention characteristics, implementation barriers/facilitators and applicability of international evidence. We performed a narrative synthesis grouped by intervention type and setting. Overall strength of evidence for admission reduction was assessed using a framework based on study design, study numbers and direction of effect.

Results

We included 124 publications/reports (30 from the UK). Integrated care and quality improvement programmes providing additional support to care homes (e.g. the English Care Homes Vanguard initiatives and hospital-based services in Australia) appeared to reduce unplanned admissions relative to usual care. Simpler training and staff development initiatives showed mixed results, as did interventions aimed at tackling specific problems (e.g. medication review). Advance care planning was key to the success of most quality improvement programmes but do-not-hospitalise orders were problematic. Qualitative research identified tensions affecting decision-making involving paramedics, care home staff and residents/family carers. The best way to reduce end-of-life admissions through access to palliative care was unclear in the face of inconsistent and generally low-quality evidence.

Conclusions

Effective implementation of interventions at various stages of residents' care pathways may reduce unplanned admissions. Most interventions are complex and require adaptation to local contexts. Work at the interface between health and social care is key to successful implementation.

Limitations

Much of the evidence identified was of low quality because of factors such as uncontrolled study designs and small sample size. Meta-analysis was not possible.

Future work

We identified a need for improved economic evidence and the evaluation of integrated care models of the type delivered by hospital-based teams. Researchers should carefully consider what is realistic in terms of study design and data collection given the current context of extreme pressure on care homes.

[Impact of CoCare, a Complex Model Intervention, on medical care in long-term care nursing homes in Germany: An overview of the outcome and process evaluation]

INTRODUCTION

More and more people are being cared for in nursing homes these days. Multimorbidity results in frequent but sometimes unnecessary patient transports and hospitalisations. The CoCare intervention was developed as a nursing home-based intervention to improve coordination of medical care and GP and specialist care in long-term care homes. The project aimed to reduce avoidable hospital admissions and ambulance transportation, minimise costs through the resulting better collaboration and improving the quality of life of nursing home residents. This article presents the results of the process and outcome evaluation of the intervention in an integrated way and assesses them against the background of the project objectives.

METHODS

Intervention and data collection started in January 2018 and ended in September 2020. A mixed-methods design was chosen for the evaluation. The (cost) effectiveness of the intervention was tested by a controlled observational study, comparing intervention (IG) and control group (CG). As part of the evaluation of the results, claims data from health insurance funds and a questionnaire-based survey among nursing staff, physicians and nursing home residents were analysed. As part of the process evaluation, subjectively perceived changes in care and implementation difficulties were recorded with the help of focus groups and telephone interviews conducted quarterly.

RESULTS

From the point of view of the health economic evaluation, with a decrease in total costs of € 468.56 (p<.001) per nursing home resident and quarter, an advantageous cost-benefit ratio can be assumed. Thus, the significant increase in outpatient care for nursing home residents goes along with a reduction of ambulance transportation by 0.19 (p=.049) and hospitalization rates by 0.08 (p=.001). In the nursing staff sample, a significant positive difference between IG (T1) and CG was observed with regard to communication and cooperation. In addition, pre-post comparison showed a significant improvement in the nursing staff's assessment of interprofessional cooperation in IG at T1 compared to T0. Both nursing staff and physicians perceived positive changes in care and positively assessed the benefit of the intervention. While practitioners experienced an intensification and improvement of communication and cooperation through the implementation of the CoCare measures, these changes were not perceived by residents.

DISCUSSION

The CoCare intervention lowered the barriers for nursing homes to contact general practitioners, specifically in unclear situations and can thus be seen as an effective tool to reduce potentially avoidable hospital admissions and costs. It is conceivable that results can be transferred to other regions in Germany and to similar care scenarios. It should be examined to what extent approaches of this new form of care can be transferred to standard care and whether adjustments to facilitate the implementation of coordinated care approaches across occupational groups in inpatient care facilities can be proposed within the framework of legislative procedures.

Economic evaluation of a medical ambulatory care service using a single group interrupted time-series design

RATIONALE

Increasing demand for hospital services can lead to overcrowding and delays in treatment, poorer outcomes and a high cost-burden. The medical ambulatory care service (MACS) provides out of hospital patient care, including diagnostic and therapeutic interventions for patients that require urgent attention, but which can be safely administered in the ambulatory environment. The programme is yet to be rigorously evaluated.

AIMS/OBJECTIVES

The aim of this study is to evaluate the impact of the MACS programme on emergency department (ED) presentations, hospital admissions, length-of-stay and health service costs from a health system perspective.

METHOD

We used a single group interrupted time series methodology with a multiple baseline approach to analyse the impact of the MACS clinic on ED presentations, hospital admissions, length-of-stay and cost outcomes for general practitioners (GP)-referred, ED-referred and ward-referred patients under two counterfactual scenarios: an increasing trend in health utilization based on preperiod predictions or a stabilization of utilization rates.

RESULTS

The time trend of hospital utilization differed after attending MACS for all three referral groups. The time trend for the GP-referred group declined significantly by 0.36 ED presentations per 100 patients per 30 days [95% confidence interval (CI): -0.52 to -0.2], while inpatient length of stay declined significantly by 1.56 and 3.70 days, respectively, per 100 ED-referred and ward-referred patients per 30 days (95% CI: -2.51 to -0.57 and -5.71 to -1.69, respectively). Under two different counterfactual scenarios, the predicted net savings for MACS across three patient groups were $78,685 (95% CI: $54,807-$102,563) and $547,639 (95% CI: $503,990-$591,287) per 100 patients over 18 months.

CONCLUSION

MACS was found to be cost-effective for GP and ward-referred groups, but the expected impact for ED-referred patients is sensitive to assumptions. Expansion of the service for GP-referred patients is expected to reduce hospitalizations the most and generate the largest net cost savings.

Protocol for a process evaluation of a stepped wedge randomised controlled trial to reduce unnecessary hospitalisations of older people from residential aged care: the EDDIE+ study

INTRODUCTION

The Early Detection of Deterioration in Elderly residents (EDDIE+) programme is a theory-informed, multi-component intervention aimed at upskilling and empowering nursing and personal care staff to identify and manage early signs of deterioration in residents of aged care facilities. The intervention aims to reduce unnecessary hospital admissions from residential aged care (RAC) homes. Alongside a stepped wedge randomised controlled trial, an embedded process evaluation will be conducted to assess the fidelity, acceptability, mechanisms of action and contextual barriers and enablers of the EDDIE+ intervention.

METHODS AND ANALYSIS

Twelve RAC homes in Queensland, Australia are participating in the study. A comprehensive mixed-methods process evaluation, informed by the integrated Promoting Action on Research Implementation in Health Services (i-PARIHS) framework, will assess intervention fidelity, contextual barriers and enablers, mechanisms of action, and the acceptability of the programme from various stakeholder perspectives. Quantitative data will be collected prospectively from project documentation, including baseline context mapping of participating sites, activity tracking and regular check-in communication sheets. Qualitative data will be collected postintervention via semi-structured interviews with a range of stakeholder groups. The i-PARIHS constructs of innovation, recipients, context and facilitation will be applied to frame the analysis of quantitative and qualitative data.

ETHICS AND DISSEMINATION

Ethical approval for this study has been granted by the Bolton Clarke Human Research Ethics Committee (approval number: 170031) with administrative ethical approval granted by the Queensland University of Technology University Human Research Ethics Committee (2000000618). Full ethical approval includes a waiver of consent for access to residents' demographic, clinical and health services de-identified data. A separate health services data linkage based on RAC home addresses will be sought through a Public Health Act application. Study findings will be disseminated through multiple channels, including journal publications, conference presentations and interactive webinars with a stakeholder network.

Detecting Acute Deterioration in Older Adults Living in Residential Aged Care: A Scoping Review

OBJECTIVES

To explore models, processes, or tools implemented in residential aged care (RAC) to support registered nurses (RNs) to identify and respond to the acute deterioration of residents.

DESIGN

Scoping literature review of English Language articles published in peer reviewed journals.

SETTINGS AND PARTICIPANTS

Studies were conducted in RAC facilities providing long-term 24-hour medical, nursing, and social care for people age 65 years or older with age-related disability.

METHODS

We completed a MESH term and key word search of MEDLINE, Embase, CINAHL, PubMed, and Google Scholar. Included studies had (1) part of the intervention based in RAC; (2) had a direct impact on RAC day to day practice; and (3) contained or provided access to the detail of the intervention. Data was charted by author, date, country, study design and the components, genesis, and efficacy of the methods used to identify and respond to acute deterioration.

RESULTS

We found 46 studies detailing models of care, clinical patterns of acute deterioration, and deterioration detection tools. It was not possible to determine which element of the models care had the greatest impact on RN decision making. The clinical patterns of acute deterioration painted a picture of acute deterioration in the frail. There was limited evidence to support the use of existing deterioration detection tools in the RAC population.

CONCLUSION AND IMPLICATIONS

We found no straight forward systematic method to support RAC RNs to identify and respond to the acute deterioration of residents. This is an important practice gap. The clinical pattern of acute deterioration described in the literature has the potential to be used for the development of a tool to support RAC RNs to identify and respond to the acute deterioration of residents.

Health economic evaluation of a nurse-led care model from the nursing home perspective focusing on residents' hospitalisations

BACKGROUND

Health economic evaluations of the implementation of evidence-based interventions (EBIs) into practice provide vital information but are rarely conducted. We evaluated the health economic impact associated with implementation and intervention of the INTERCARE model-an EBI to reduce hospitalisations of nursing home (NH) residents-compared to usual NH care.

METHODS

The INTERCARE model was conducted in 11 NHs in Switzerland. It was implemented as a hybrid type 2 effectiveness-implementation study with a multi-centre non-randomised stepped-wedge design. To isolate the implementation strategies' costs, time and other resources from the NHs' perspective, we applied time-driven activity-based costing. To define its intervention costs, time and other resources, we considered intervention-relevant expenditures, particularly the work of the INTERCARE nurse-a core INTERCARE element. Further, the costs and revenues from the hotel and nursing services were analysed to calculate the NHs' losses and savings per resident hospitalisation. Finally, alongside our cost-effectiveness analysis (CEA), a sensitivity analysis focused on the intervention's effectiveness-i.e., regarding reduction of the hospitalisation rate-relative to the INTERCARE costs. All economic variables and CEA were assessed from the NHs' perspective.

RESULTS

Implementation strategy costs and time consumption per bed averaged 685CHF and 9.35 h respectively, with possibilities to adjust material and human resources to each NH's needs. Average yearly intervention costs for the INTERCARE nurse salary per bed were 939CHF with an average of 1.4 INTERCARE nurses per 100 beds and an average employment rate of 76% of full-time equivalent per nurse. Resident hospitalisation represented a total average loss of 52% of NH revenues, but negligible cost savings. The incremental cost-effectiveness ratio of the INTERCARE model compared to usual care was 22'595CHF per avoided hospitalisation. As expected, the most influential sensitivity analysis variable regarding the CEA was the pre- to post-INTERCARE change in hospitalisation rate.

CONCLUSIONS

As initial health-economic evidence, these results indicate that the INTERCARE model was more costly but also more effective compared to usual care in participating Swiss German NHs. Further implementation and evaluation of this model in randomised controlled studies are planned to build stronger evidential support for its clinical and economic effectiveness.

What factors influence nursing home use of hospital avoidance programs? An interview study

AIMS

To understand why some nursing homes use hospital avoidance programs more frequently than others.

DESIGN

Two hospital avoidance programs, called residential-in-reach services in Victoria, Australia, were evaluated using a qualitative descriptive design.

METHODS

Between 2014 and 2018, 127 semi-structured interviews were conducted with staff from nursing homes, general practitioners and staff from the residential-in reach services. The interviews took an average of 45 min and transcripts were thematically analysed.

RESULTS

Nursing home reliance on residential-in-reach services to manage deteriorating residents was evident in both evaluations. Irrespective of the model of service provision, reliance was associated with: the increased care needs of residents; difficulties accessing timely and appropriate medical care; and the reduced numbers of skilled registered nurses to assess and manage deteriorating residents.

CONCLUSION

The residential-in-reach services are highly regarded by nursing homes. However, some are reliant on these services to provide nursing assessment and management. Using residential-in-reach services to substitute for nursing care, deskills nurses and shifts the cost of providing care from the service provider to other agencies. To provide residents with quality nursing care, the number of skilled registered nurses able to work within their scope of practice needs to be increased in Australian nursing homes.

IMPACT

The findings highlight the challenges of providing care in older people living in aged care. Increasing the number of skilled registered nurses in Australian nursing homes, would support deteriorating residents to stay in familiar surroundings and reduce reliance on external services to provide nursing care.

A stepped-wedge randomised controlled trial assessing the implementation, effectiveness and cost-consequences of the EDDIE+ hospital avoidance program in 12 residential aged care homes: study protocol

Background

Older people living in residential aged care homes experience frequent emergency transfers to hospital. These events are associated with risks of hospital acquired complications and invasive treatments or interventions. Evidence suggests that some hospital transfers may be unnecessary or avoidable. The Early Detection of Deterioration in Elderly residents (EDDIE) program is a multi-component intervention aimed at reducing unnecessary hospital admissions from residential aged care homes by empowering nursing and care staff to detect and manage early signs of resident deterioration. This study aims to implement and evaluate the program in a multi-site randomised study in Queensland, Australia.

Methods

A stepped-wedge randomised controlled trial will be conducted at 12 residential aged care homes over 58 weeks. The program has four components: education and training, decision support tools, diagnostic equipment, and implementation facilitation with clinical systems support. The integrated Promoting Action on Research Implementation in Health Services (i-PARIHS) framework will be used to guide the program implementation and process evaluation. The primary outcome measure will be the number of hospital bed days used by residents, with secondary outcomes assessing emergency department transfer rates, admission rates, length of stay, family awareness and experience, staff self-efficacy and costs of both implementation and health service use. A process evaluation will assess the extent and fidelity of program implementation, mechanisms of impact and the contextual barriers and enablers.

Discussion

The intervention is expected to improve outcomes by reducing unnecessary hospital transfers. Fewer hospital transfers and admissions will release resources for other patients with potentially greater needs. Residential aged care home staff might benefit from feelings of empowerment in their ability to proactively manage early signs of resident deterioration. The process evaluation will be useful for supporting wider implementation of this intervention and other similar initiatives.

Trial registration

The trial is prospectively registered with the Australia New Zealand Clinical Trial Registry (ACTRN12620000507987, registered 23/04/2020).
