Background Targeted antibiotic treatment reduces the infection risk of open fractures when soft tissue and bone are exposed to the environment. The risk of infection increases with higher degrees of injury. The Gustilo‐Anderson system was developed to identify the degree of injury of open fractures and can be utilized to guide initial antibiotic therapy. Few studies have been published evaluating the potential impact of emergency medicine pharmacists in trauma, and currently no study has evaluated a pharmacist's influence on antibiotic selection and timing for open fractures. Objective The objective of this study was to determine the impact of an emergency medicine pharmacist on initial antibiotic selection and timing in trauma patients with open fractures. Methods This was a retrospective cohort study. Trauma alerts with open fractures from May 1, 2014 to June 30, 2016 were eligible for inclusion. The primary outcome was to determine if pharmacist participation during trauma resuscitation was associated with an increased proportion of initial antibiotic selection meeting guideline recommendations. The secondary outcome was the door‐to‐antibiotic administration time during resuscitation. Results Initial prophylactic antibiotic recommendations were met in 81% of trauma resuscitations when a pharmacist was present versus 47% without a pharmacist present (p < 0.01). The median door‐to‐antibiotic time was 14 min in the PHARM group versus 20 min in the NO‐PHARM group (p = 0.02). Conclusions The participation of an EM pharmacist during initial trauma resuscitation resulted in improved initial antibiotic selection and faster door‐to‐antibiotic administration times in trauma patients with open fractures.
