Do patient outcomes differ when the trauma team leader is a surgeon or non-surgeon? A multicentre cohort study

Purpose Trauma team leaders (TTLs) have traditionally been general surgeons; however, some trauma centres use a mixed model of care where both surgeons and non-surgeons (primarily emergency physicians) perform this role. The objective of this multicentre study was to provide a well-powered study to determine if TTL specialty is associated with mortality among major trauma patients. Methods Data were collected from provincial trauma registries at six level 1 trauma centres across Canada over a 10-year period. We included adult trauma patients (age ≥ 18 yrs) who triggered the highest-level trauma activation. The primary outcome was the difference in risk-adjusted in-hospital mortality for trauma patients receiving initial care from a surgeon versus a non-surgeon TTL. Results Overall, 12,961 major trauma patients were included in the analysis. Initial treatment was provided by a surgeon TTL in 57.8% ( n = 7513) of cases, while 42.2% ( n = 5448) of patients were treated by a non-surgeon TTL. Unadjusted mortality occurred in 11.6% of patients in the surgeon TTL group and 12.7% of patients in the non-surgeon TTL group (OR 0.87, 95% CI 0.78–0.98, p = 0.02). Risk-adjusted mortality was not significantly different between patients cared for by surgeon and non-surgeon TTLs (OR 0.92, 95% CI 0.80–1.06, p = 0.23). Furthermore, we did not observe differences in risk-adjusted mortality for any of the subgroups evaluated. Conclusions After risk adjustment, there was no difference in mortality between trauma patients treated by surgeon or non-surgeon TTLs. Our study supports emergency physicians performing the role of TTL at level 1 trauma centres.
