fa الگوی مصرف آنتی‌بیوتیک‌ها در بخش‌های بیمارستان ولیعصر زنجان کارآزمایی بالینی Clinical Trials <p><strong><em>Background and Objective</em></strong>: Unreasonable prescription and indiscriminate use of antibiotics bring about increased antimicrobial resistance. Evaluating the pattern of use seems to be a perfect procedure to improve its reasonable prescription.

Infectious Unit of the hospital has been used most frequently (27%) than other units. The most frequent antibiotics used in the hospital units were Cephalosporins followed by Macrolides and Fluoroquinolones with a mean of 48.5%, 17.22% and 12%, respectively.</p> <p><strong><em>Conclusion</em></strong><strong>:</strong> In comparison with similar studies, on average the prescribing rate of antibacterials in Vali Asr Hospital might have been less than other hospitals in Iran.
