Determining the Pattern of Antibiotics Usage among the Patients Hospitalized to the Teaching Hospitals of Ahvaz

Abstract Introduction: Antibiotics are one of the most important drugs used in treatment. Because of the cost and association of their use with resistance to them, their consumption pattern is important and the first step is to optimize the use of such drugs. Objective: Since the use of prophylactic antibiotics was also unreasonable and occasionally continued while the patient was hospitalized, the use of such prophylaxies was also considered. We decided to determine the pattern of antibiotic use in the different wards of three educational hospitals of Ahvaz (Golestan, Imam Khomeini and Razi). Materials and Methods: This study was a descriptive cross-sectional study that evaluated the pattern of antibiotic use in three hospitals of Golestan, Razi and Imam Khomeini (RA) in Ahvaz. 1554 patients were enrolled in three hospitals and items such as age, sex, ward, start and end dates, administration intervals, dosage, and the type of antibiotic used were evaluated. 759 received systemic antibiotics. Antibiotics administration was analyzed separately and completely in hospitals and departments based on DDD / 100 Bed days (consumed per 100 bed occupied days) and the results were evaluated. Results: 48.8% of the patients received antibiotics, equivalent to 93.9 DDD / 100 Bed days. 90% of the antibiotics were injected and 10% oral. The highest use of antibiotics was in the Golestan Hospital and the lowest in the Razi Hospital. Among the wards, the highest rate was in the infectious ward of the Razi Hospital (226) and the lowest in Neonatal Department of Imam Khomeini Hospital (5.7). The most used antibiotics were first-generation cephalosporins (20%) or 21% of total consumption, and the highest belonged to cefazolin (18). Conclusion: Antibiotic use in these hospitals was very high, as evaluated, which needs to be reviewed inthe light of the association between incorrect use of antibiotics, emerging resistance and increased cost of treatment.
