Evaluation of nurse practitioners' extended scope of practice in a regional hospital emergency department in tropical Australia.

Objectives: There is very little literature examining the workload and impact of nurse practitioners (NPs) working in emergency departments (ED) in regional and rural Australia. The aim of this paper was to review the ED NPs scope of practice in the ED discharge stream and patient outcomes at Cairns Hospital over a 7-month period.

Methods: This retrospective study examined the ED electronic medical record between 14 May 2019 and 31 December 2019. Cases managed by ED NPs, referrals, procedures performed, representations and disposition data were collected. Adverse events were sought from the Qld Health adverse events register (Riskman), the department complaints register and the ED M&M meeting minutes.

Results: A total of 1443 patients were treated by NPs, with ages ranging from 0 to 98 years (median 40 years). Australasian Triage Score (ATS) 3 cases made up 30% of the workload. Other than ATS 3 cases, time to being seen was better than the general department. There were very few unexpected representations, complaints or adverse events.

Conclusions: This study supports the view that NPs working in a regional emergency department can safely manage a variety of patients outside a fast-track model, with a wide age range and a variety of triage categories and diagnoses. We believe this has important implications for the provision of emergency care, especially in regional and rural Australia.
