Abstract Objective eCTAS is a real‐time electronic decision‐support tool designed to standardize the application of the Canadian Triage and Acuity Scale (CTAS). This study addresses the variability of CTAS score distributions across institutions pre‐ and post‐eCTAS implementation. Methods We used population‐based administrative data from 2016–2018 from all emergency departments (EDs) that had implemented eCTAS for 9 months. Following a 3‐month stabilization period, we compared 6 months post‐eCTAS data to the same 6 months the previous year (pre‐eCTAS). We included triage encounters of adult (≥17 years) patients who presented with 1 of 16 pre‐specified, high‐volume complaints. For each ED, consistency was calculated as the absolute difference in CTAS distribution compared to the average of all included EDs for each presenting complaint. Pre‐eCTAS and post‐eCTAS change scores were compared using a paired‐samples t‐test. We also assessed if eCTAS modifiers were associated with triage consistency. Results There were 363,214 (183,231 pre‐eCTAS, 179,983 post‐eCTAS) triage encounters included from 35 EDs. Triage scores were more consistent (P

PURPOSE: Acute asthma is a common emergency department (ED) presentation and variation in its management is well recognized. The present study examined the use of an asthma care map (ACM) in one Canadian ED to improve adherence to acute asthma guidelines, emphasizing the use of systemic corticosteroids (SCSs) and inhaled corticosteroids (ICSs).
