Background: Antibiotics can be life saving if they are used correctly, and can have unwanted side effects specially resistance with incorrect use. Unfortunately in fear of no response, physicians use broad spectrum antibiotics meticulously. In this Drug Utilization Evaluation (DUE), improper use of Vancomycin and five broad-spectrum antibiotics are studied to find faults and solution for this problem.Methods: This descriptive cross-sectional study performed during the March of 2012 to March of 2013.DUE of Imipenem, Meropenem, Piperacillin-Tazobactam, Cefepime, Ciprofloxacin and Vancomycin was done in 6 wards of Imam Hossein Hospital in Tehran. Demographic, clinical, laboratory, imaging and treatment data were looked for in medical records of 686 patients. Evaluation was done by three infectious disease specialist based on reference text book of Mandell’s Principles and Practice of Infectious Diseases 2010 and IDSA Guidelines.Results: This study showed 38.5% of prescriptions were correct and the remained 61.5% were incorrect with different faults predominantly incorrect overuse in 51.1%.Ciprofloxacin was the most common incorrect used drug in 74.8% cases and Piperacillin-Tazobactam with 48.7% cases had the least common incorrect use. There was no fault in prescription of antibiotics observing age and sex (pregnancy, breast feeding) factors.Conclusions: Our results reveal a significant high level of the inappropriate use of Antibiotics mostly as overuse and empirically without culture results. It is needed to establish continuing medical education (CME) courses and a locally conformable guideline of antibiotic use based on antibiogram results.
