Prophylactic Antibiotics in Otolaryngologic Surgeries: From Knowledge to Practice

Introduction: The management and use of antimicrobial drugs has clinical, economic, and environmental implications. In many countries, antimicrobial drugs are the most frequently prescribed therapeutic agents. Therefore, health-care policy should focus on how to establish a rational attitude toward antibiotics. This study was performed to investigate antibiotic usage as a prophylactic regimen in head and neck surgeries.  Materials and Methods: This study was a retrospective case series. Patients undergoing otolaryngology surgeries in a tertiary referral otolaryngology center were included. Members of operating room staff that were unaware of the study objectives collected patients’ data using a questionnaire that contained information regarding general medical condition, disease, surgical procedure, and prophylaxis regimen and duration.   Results: Excluding infected patients, we studied ۱۳۴۹ patients during a four-month period who needed prophylactic antibiotics. A total of ۳۴ different types of surgical procedures were performed. Out of the total number of patients, ۵۰۳ (۳۷.۰%) received a parenteral antibiotic directly before surgery. The main antibiotics used before surgery were cephalosporins (۹۴.۹%). All of the ۱۳۴۹ patients were administered antibiotics after the procedure. These antibiotics where given with a mean number of doses of ۴.۸۱ (range: ۱–۶۸), and also consisted of mostly cephalosporins. Conclusion: Our results indicate that prophylactic antibiotics were being significantly misused in a tertiary referral center of a university hospital. Although teaching the principles of prophylaxis to physicians is important, we think that finding a way to bring this knowledge to practice is more important.
