RESUMEN
We investigated adherence to the Hospital Infection Control Practice Advisory Committee [HICPAC] guidelines on vancomycin prescription in a large university-affiliated hospital in Shiraz. From August to December 2003, 200 hospitalized patients received vancomycin. For only 12 [6%] of these patients was vancomycin prescribed appropriately according to HICPAC guidelines. The main reasons why vancomycin use did not comply with HICPAC recommendations were: surgical prophylaxis in patients with negative cultures for resistant Gram-positive organisms, no investigation of vancomycin serum levels in patients receiving > 48 hours of vancomycin, vancomycin serum levels not repeated in patients receiving > 1 week of vancomycin, no appropriate adjustment of dosage with respect to serum levels in patients receiving vancomycin
