Background: In the advent of increasing antibiotic resistance, several studies sought to determine antibiotic prescription trends; however, no pattern has been firmly identified particularly for the burned population. We performed a query of burned patients in a large established database to understand differences in antibiotic use related to patient-specific factors. Methods: Burned patients with systemic antibiotics given within 7 days of injury were identified on the TriNetX database. The patient population was stratified by age, 1-year time intervals of antibiotic prescription from 2004 to 2019, time of antibiotic prescription in 1-day intervals after injury, and % TBSA burned in 10% intervals ranging from < 10% to > 90%. Data were analyzed using χ2 with p < 0.05 considered significant. Pearson coefficients (r2) values were used to correlate differences in antibiotic prescription between age groups and to changes over time. Results: Stratification by age revealed higher use of antibiotics in older burned patients compared to younger patients. Surprisingly, 87.6% of burn patients of those who received antibiotic therapy was on the day of injury. Penicillins and beta-lactam antimicrobials were used most often at a frequency of 64%. No statistically significant differences in rates of antibiotic therapy were observed in burned patients when stratified by %TBSA burned. Conclusions: The study elucidates current patterns of antibiotic use in burn care in the United States, allowing for improved understanding of both past and present patterns of antibiotic prescription.
