Implementation and evaluation of a nurse-led intervention to augment an existing residential aged care facility outreach service with a visual telehealth consultation: stepped-wedge cluster randomised controlled trial.

BACKGROUND: Up to 75% of residents from residential aged care facilities (RACF) are transferred to emergency departments (ED) annually to access assessment and care for unplanned or acute health events. Emergency department presentations of RACF residents can be both expensive and risky, and many are unnecessary and preventable. Processes or triage systems to assess residents with a health event, prior to transfer, may reduce unnecessary ED transfer. The Aged Care Emergency (ACE) service is a nurse-led ED outreach service that provides telephone support to RACF nurses regarding residents' health events. This service is available Monday to Friday, 8am to 4 pm (ED ACE hours). The primary objective of this study was to assess whether the augmentation of the phone-based ED ACE service with the addition of a visual telehealth consultation (VTC) would reduce RACF rate of ED presentations compared to usual care. The secondary objectives were to 1) monitor presentations to ED within 48 h post VTC to detect any adverse events and 2) measure RACF staff perceptions of VTC useability and acceptability. METHODS: This implementation study used a stepped wedge cluster randomised controlled trial design. Study settings were four public hospital EDs and 16 RACFs in two Local Health Districts. Each ED was linked to 4 RACFs with approximately 350 RACF beds, totalling 1435 beds across 16 participating RACFs. Facilities were randomised into eight clusters with each cluster comprising one ED and two RACFs. RESULTS: A negative binomial regression demonstrated a 29% post-implementation reduction in the rate of ED presentations (per 100 RACF beds), within ED ACE hours (IRR [95% CI]: 0.71 [0.46, 1. 09]; p = 0.122). A 29% reduction, whilst not statistically significant, is still clinically important and impactful for residents and EDs. A post-hoc logistic regression demonstrated a statistically significant 69% reduction in the probability that an episode of care resulted in an ED presentation within ED ACE hours post-implementation compared to pre-implementation (OR [95% CI]: 0.31 [0.11, 0.87]; p = 0.025). CONCLUSION: Findings have shown the positive impact of augmenting ACE with a VTC. Any reduction of resident presentations to a busy ED is beneficial to healthcare overall, but more so to the individual older person who can recover safely and comfortably in their own RACF.

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 in 141 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, multiagency 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.

Reducing Hospital Transfers from Aged Care Facilities: A Large-Scale Stepped Wedge Evaluation.

BACKGROUND/OBJECTIVES: Older people living in residential aged care facilities (RACFs) experience acute deterioration requiring assessment and decision making. We evaluated the impact of a large-scale regional Aged Care Emergency (ACE) program in reducing hospital admissions and emergency department (ED) transfers. DESIGN: A stepped wedge nonrandomized cluster trial with 11 steps, implemented from May 2013 to August 2016. SETTING: A large regional and rural area of northern and western New South Wales, Australia. PARTICIPANTS: Nine hospital EDs and 81 RACFs participated in the evaluation. INTERVENTION: The ACE program is an integrated nurse-led intervention underpinned by a community of practice designed to improve the capability of RACFs managing acutely unwell residents. It includes telephone support, evidence-based algorithms, defining goals of care for ED transfer, case management in the ED, and an education program. MEASUREMENTS: ED transfers and subsequent hospital admissions were collected from administrative data including 13 months baseline and 9 months follow-up. RESULTS: A total of 18,837 eligible ED visits were analyzed. After accounting for clustering by RACFs and adjusting for time of the year as well as RACF characteristics, a statistically significant reduction in hospital admissions (adjusted incident rate ratio = .79; 95% confidence interval [CI] = .68-.92); P = .0025) was seen (i.e., residents were 21% less likely to be admitted to the hospital). This was also observed in ED visit rates (adjusted incidence rate ratio = .80; 95% CI = .69-.92; P = .0023) (i.e., residents were 20% less likely to be transferred to the ED). Seven-day ED re-presentation fell from 5.7% to 4.9%, and 30-day hospital readmissions fell from 12% to 10%. CONCLUSION: The stepped wedge design allowed rigorous evaluation of a real-world large-scale intervention. These results confirm that the ACE program can be scaled up to a large geographic area and can reduce ED visits and hospitalization of older people with complex healthcare needs living in RACFs.
