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.

BackgroundReducing avoidable hospitialisation of aged care facility (ACF) residents can improve the resident experience and their health outcomes. Consequently many variations of hospital avoidance (HA) programs continue to evolve. Nurse practitioners (NP) with expertise in aged care have the potential to make a unique contribution to hospital avoidance programs. However, little attention has been dedicated to service evaluation of this model and the quality of care provided. The purpose of this study was to evaluate the quality of an aged care NP model of care situated within a HA service in a regional area of Australia.MethodsDonabedian’s structure, process and outcome framework was applied to evaluate the quality of the NP model of care. The Australian Nurse Practitioner Study standardised interview schedules for evaluating NP models of care guided the semi-structured interviews of nine health professionals (including ACF nurses, medical doctors and allied health professionals), four ACF residents and their families and two NPs. Theory driven coding consistent with the Donabedian framework guided analysis of interview data and presentation of findings.ResultsStructural dimensions identified included the ‘in-reach’ nature of the HA service, distance, limitations of professional regulation and the residential care model. These dimensions influenced the process of referring the resident to the NP, the NPs timely response and interactions with other professionals. The processes where the NPs take time connecting with residents, initiating collaborative care plans, up-skilling aged care staff and function as intra and interprofessional boundary spanners all contributed to quality outcomes. Quality outcomes in this study were about timely intervention, HA, timely return home, partnering with residents and family (knowing what they want) and resident and health professional satisfaction.ConclusionsThis study provides valuable insights into the contribution of the NP model of care within an aged care, HA service and how staff manipulated the process dimensions to improve referral to the NPs. NP service in this study was dynamic, flexible and responsive to both patient and organisational demands.

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.
