Background: Timely and limited antibiotic prophylaxis (postinjury antimicrobial therapy) targeting specific traumatic injuries is a well-recognized measure to lessen posttraumatic infection. Modern military combat injuries raise significant challenges because of complex multiple injuries and limited data derived directly from well-controlled trials to base recommendations. Expert consensus review of available evidence led to published guidance for selection and duration of antimicrobial therapy for combat-related trauma infection prevention. This analysis evaluates antibiotic-prescribing practices by military physicians in the operational theater relative to the published guidance. Methods: Trauma history and infectious disease-specific inpatient care information is captured through the Joint Theater Trauma Registry along with a supplemental infectious disease module. Injury patterns are classified based on documented International Classification of Diseases-9th Revision codes with a composite assessment of each patient's injury pattern. Antimicrobial use categorized as prophylaxis is prescribed within the first 48 hours postinjury. Adherence to published guidance is reported along with patient characteristics and injury severity to assess for potential explanations of nonadherence. Results: During June to November 2009, 75% of the 610 eligible trauma patients received antimicrobial prophylaxis. Adherence to the recommended antibiotic agent on the day of injury was in the range of 46% to 50% for the most common extremity injury patterns and <10% in penetrating abdominal injuries. Antibiotics were given in 39% of patients sustaining injuries that are recommendations to not receive antimicrobial prophylaxis. Conclusions: This first evaluation of combat trauma-related antibiotic prophylaxis shows adherence levels comparable or superior to reported rates in civilian settings despite the austere, frequently mass casualty environment. Areas for interval surveillance and education-based strategies for improved adherence to practice guidance are identified.
