BackgroundTo evaluate a Geriatric Emergency Department Intervention (GEDI) model of service delivery for adults aged 70 years and older.MethodsA pragmatic trial of the GEDI model using a pre-post design. GEDI is a nurse-led, physician-championed, Emergency Department (ED) intervention; developed to improve the care of frail older adults in the ED. The nurses had gerontology experience and education and provided targeted geriatric assessment and streamlining of care. The final format included 2.4 full time equivalent nurses working 7 days from 0700 h to 1730 h (1530 h at weekends). There were three implementations periods: pre-implementation (2012); a developmental phase from January 2013 to August 2015; and full implementation from September 2015 to August 2016. The outcomes measured were disposition (discharged home, admitted or died); ED length of stay; hospital length of stay; all cause in-hospital mortality within 28 days; time to ED re-presentation up to 28 days post-discharge; in-hospital costs.The setting was a tertiary hospital ED, with 385 beds, in Queensland, Australia. Approximately 53,000 patients presented to the ED annually with 20% aged 70 years and older. All patients over the age 70 who presented to the ED between January 2012 and August 2016 (n = 44,983) were included in the trial.ResultsOlder persons who presented to the ED when the GEDI team were working had increased likelihoods of discharge (Hazard ratio (HR) = 1.19; 95% CI: 1.13–1.24) and reduced ED length of stay (HR = 1.42; 95% CI: 1.33–1.52) compared with those who presented when GEDI were not working. There was no increase in the risk of mortality (HR = 1.01; 95% CI = 0.23–4.43) or risk of same cause re-presentation to 28 days (HR = 1.21; 95% CI: 0.99–1.49). The GEDI service resulted in average cost savings per ED presentation of $35 [95% CI, $21, $49] and savings of $1469 [95% CI, $1105, $1834] per hospital admission.ConclusionsImplementation of a nurse-led physician-championed model of ED care, focused on frail older adults, reduced ED length of stay, hospital admission and if admitted, hospital length of stay and cost, without increasing mortality or same cause re-presentation. These increases were sustained over time and after the initial implementation team had changed roles.Trial registrationAustralian Clinical Trials Registration Number ACTRN12615001157561 - retrospectively registered on 29/10/2015.

BackgroundEmergency departments are chaotic environments in which complex, frail older persons living in the community and residential aged care facilities are sometimes subjected to prolonged emergency department lengths of stay, excessive tests and iatrogenic complications. Given the ageing population, the importance of providing appropriate, quality health care in the emergency department for this cohort is paramount. One possible solution, a nurse-led, physician-championed, emergency department gerontological intervention team, which provides frontload assessment, early collateral communication and appropriate discharge planning, has been developed. The aim of this Geriatric Emergency Department Intervention is to maximise the quality of care for this vulnerable cohort in a cost effective manner.MethodsThe Geriatric Emergency Department Intervention research project consists of three interrelated studies within a program evaluation design. The research comprises of a structure, process and outcome framework to ascertain the overall utility of such a program. The first study is a pre-post comparison of the Geriatric Emergency Department Intervention in the emergency department, comparing the patient-level outcomes before and after service introduction using a quasi-experimental design with historical controls. The second study is a descriptive qualitative study of the structures and processes required for the operation of the Geriatric Emergency Department Intervention and clinician and patient satisfaction with service models. The third study is an economic evaluation of the Geriatric Emergency Department Intervention model of care.DiscussionThere is a paucity of evidence in the literature to support the implementation of nurse-led teams in emergency departments designed to target frail older persons living in the community and residential aged care facilities. This is despite the high economic and patient morbidity and mortality experienced in these vulnerable cohorts. This research project will provide guidance related to the optimal structures and processes required to implement the model of care and the associated cost related outcomes.Trial registrationAustralian New Zealand Clinical Trials Registration Number is 12615001157561.

As population's age and people live longer, the burden on acute health care services associated with the frail aged increases. Recognising the needs of this cohort as well as designing and evaluating interventions to manage their care in the emergency department has been reported in the literature. Transition to new models of care in emergency departments (ED) focused on improving the care of older people can also assist in reducing length of stay in the ED, reducing complications associated with ED presentation and prevent inappropriate hospitalisation. The Geriatric Emergency Department Intervention (GEDI) aims to build on the successful components of other models of care for older people in acute healthcare settings to improve safety and best meet the needs of both older people and health service providers.

This article discusses an innovative way of caring for older adults in an ageing population utilising the existing evidence. A formal evaluation is currently underway.

Objective: As the population of Australia ages, EDs will experience an increasing frequency of presentations of older adults from residential aged care facilities (RACFs). These presentations are often complex and time consuming in the chaotic and potentially hazardous ED environment. The Geriatric Emergency Department Intervention (GEDI) model was developed to optimise the care of frail older adults, especially RACF residents, in the ED. The aim of the present study was to evaluate the effectiveness of the GEDI model on the primary outcomes of disposition (admission, discharge or death) and ED length of stay for residents of RACFs, presenting to an ED in regional Queensland, Australia. Methods: GEDI is a nurse-led, physician-championed, innovative model delivered by advanced practice nurses with expertise in gerontology. This quasi-experimental pragmatic study compared outcomes for RACF residents who presented to a regional Queensland ED during three time periods: pre-GEDI, interim GEDI and post-GEDI implementation of the GEDI model. Outcomes included disposition, ED length of stay, ED representation and mortality. Results: A significant increase in the likelihood of discharge from ED (hazard ratio 1.15, 95% confidence interval 1.05-1.26) and reductions in ED length of stay (hazard ratio 1.49, 95% confidence interval 1.24-1.78) were evident for RACF residents following the implementation of the GEDI intervention. There were no differences in mortality, ED re-presentation or in-hospital length of stay between the three time periods. Conclusion: There is a paucity of evidence to support the implementation of nurse-led teams in EDs designed to target older adults living in RACFs. The GEDI model was effective in reducing ED length of stay while increasing the likelihood of safe discharge for RACF residents. Key findings• The GEDI is a physicianchampioned, nurse-led model designed to improve care and reduce unnecessary hospitalisation of frail older adults. • The GEDI model decreases the ED length of stay for RACF residents. • The GEDI model increased the likelihood of safe ED discharge for RACF residents.
