ABSTRACT
We evaluated the appropriateness of antibiotic prophylaxis administered before surgery at a major referral hospital in Shiraz, against the American Society of Hospital Pharmacists [ASHP] guidelines. Data on surgical procedure, choice of antibiotic and administration were gathered for all surgeries performed on hospitalized patients during 15 days in March 2010, Of 155 patients included in the analysis, 98% received prophylactic antibiotic before surgery; according to ASHP guidelines, prophylaxis was needed in only 106 [68.4%]. Of these 106, only 8 patients received the correct antibiotic regimen. The commonest regimens administered were cefazolin + gentamicin [47.6%], cefazolin [20.5%] and cefuroxime [8.5%]. Antibiotic prophylaxis was continued in 83% of cases, while this was necessary in only 37%. In only 1 surgical procedure were all evaluated parameters correct
