Effect of Resident Involvement on Trauma Patient Outcomes: A Single-Institution Review

Abstract

The purpose of this study was to examine the mortality difference and other outcome measures amongst trauma patients with residents involved in the initial management versus those that were managed by attending physicians only without resident involvement. Retrospective review. Chi-square, Fisher's tests were used to analyze the outcomes, diagnostics, and interventions using the presence of residents in the initial care of patients as an independent variable. Linear and logistic regression were used to estimate adjusted outcomes. Riverside Community Hospital, Riverside California (State-designated level I trauma center) PARTICIPANTS: Data on all trauma patients ≥18 years old that were admitted between July 1, 2018 and June 30, 2020 was collected retrospectively (total 2644 trauma patients). Trauma patients that were transferred from outside facilities were excluded from the study. There was no significant difference in mortality associated with resident involvement in both unadjusted and adjusted analysis. Patients treated by residents, however, had more comorbidities (higher CCI) and were more severely injured (higher ISS). On adjusted analysis, higher ISS was independently associated with resident presence. There was also a statistically significant increase in the use of diagnostic studies and therapeutic interventions in the resident-present group. Involvement of residents in the initial management of our trauma patient population was associated with no difference in overall mortality or morbidity, despite higher injury severity in the resident treated patient group.
