Adherence to American Society of Health‐System Pharmacists guidelines for antibiotic prophylaxis in thoracic surgery: a prospective observational study

Abstract

AbstractBackgroundSurgical antibiotic prophylaxis (SAP) decreases the incidence of surgical site infections. However, inappropriate use of prophylactic antibiotics may lead to antibiotic resistance, prolonged hospital stay and adverse drug reactions.AimThis prospective study aimed to assess the concordance of prophylactic antibiotic administration for thoracic operations in Iran with American Society of Health‐System Pharmacists (ASHP) guidelines.MethodsThe appropriateness of SAP administration in 222 thoracic operations was assessed in a respiratory referral centre over a period of 4 months. Demographic, clinical and SAP data were recorded from patient files. ASHP guidelines were used to evaluate the appropriateness of prophylactic antibiotic administration.ResultsCefazolin was correctly prescribed for approximately 70% of patients who required antibiotic prophylaxis. SAP was administered at the correct time (within 60 min before surgery) for 71.6% of surgeries. Intraoperative doses were correctly given in 27.7% of prolonged procedures. In 86.7% of surgeries, antibiotic administration was continued for more than 24 h after surgery (based on a physician's opinion or recent microbiological cultures).ConclusionThe results suggest a relatively low rate of consistency between SAP administration and ASHP guidelines in Iran. A long duration of antibiotic administration after operations is an important finding, which should be considered and re‐evaluated by thoracic surgeons in Iran.
