Evaluation of indications and efficacy of doxycycline for surgical antibiotic prophylaxis

Given medical advancements in global healthcare systems over the past decade, it may be reasonable to assume that the incidence of surgical site infections would have decreased; however, surveillance data indicate that these rates have held constant. Surgical prophylaxis guidelines from the United States and United Kingdom recommend cefazolin, vancomycin and clindamycin in most surgeries for no longer than 24 hours. As a result of medication shortages impacting the global supply chain, surgeons have needed to evaluate alternative perioperative antibiotics, such as doxycycline; however, research into using doxycycline for preventing surgical site infections is limited. The goal of this study is to retrospectively assess doxycycline's efficacy, safety and role in preventing surgical site infections.
