Background Emergency access targets have been implemented A ustralia‐wide following recent retrospective cohort studies linking emergency department ( ED ) overcrowding and excess mortality. Aim To examine the impact of ED access targets on the characteristics and health service utilisation of general medicine ( GM ) inpatients at the R oyal M elbourne H ospital. Methods A retrospective cohort study was conducted on all patient episodes admitted from ED to GM units from J anuary 2009 to D ecember 2012 ( n = 15562), compared in two cohorts for 24 months before ( n = 7393) and after ( n = 8169) the implementation of the ‘4‐h rule’. The main outcome measures were age, comorbidity, clinical urgency at presentation (Australasian Triage Score), ED and inpatient length of stay, diagnosis at discharge, and in‐hospital complications. Results After the implementation of the ‘4‐h rule’, there was an increased proportion of younger patients aged ≤50 years (7.7–9.1%), urgent Australasian Triage Scale 3 (45.6–49.7%) and semi‐urgent Australasian Triage Scale 4 (21.8–27.6%) patients admitted to GM . On average, GM patients had fewer comorbid conditions (proportion with Charlson score ≥6 decreased from 14.2% to 11.9%), and higher proportions (21.8–24.7%) were admitted for less than 48 h. Conclusion Implementation of a 4‐h access target has been associated with changes to the characteristics of patients admitted to GM , including higher proportions of younger patients, with fewer comorbid conditions and lower clinical urgency at presentation, although the latter may be explained by a coincidental change in the way that ED patients were triaged, as well as a greater number of these patients presenting to ED overall.
