Background: The trauma team leader (TTL) is a "model" of a specifically dedicated team leader in the emergency department (ED), but its benefits are uncertain. The primary objective was to assess the impact of the TTL on 72-hour mortality. Secondary objectives included 24-hour mortality and admission delays from the ED.
Methods: Major trauma admissions (Injury Severity Score (ISS)≥12) in 3 Canadian Level-1 trauma centres were included from 2003 to 2017. The TTL program was implemented in centre 1 in 2005. An interrupted time series (ITS) analysis was performed. Analyses account for the change in patient case-mix (age, sex, and ISS). The two other centres were used as control in sensitivity analyses RESULTS: Among 20,193 recorded trauma admissions, 71.7% (n=14,479) were males. The mean age was 53.5 ± 22.0 years. The median [IQR] ISS was 22 [16-26]. TTL implementation was not associated with a change in the quarterly trends of 72-hour or 24-hour mortality: adjusted estimates with 95% CI were 0.32 [-0.22;0.86] and -0.07 [-0.56;0.41] percentage-point change. Similar results were found for the proportions of patients admitted within 8 hours of ED arrival (0.36 [-1.47;2.18]). Sensitivity analyses using the two other centres as controls yielded similar results.
Conclusion: TTL implementation was not associated with changes in mortality or admission delays from the ED. Future studies should assess the potential impact of TTL programs on other patient-centred outcomes using different quality of care indicators.
