Evaluation of prescribing pattern of vancomycin at the Payambar-e-Azam Hospital of Bandar Abbas

Due to the significant use of vancomycin antibiotic in hospitals and the need for rational use of this antibiotic to prevent the occurrence of antibiotic resistance, the present study was conducted to evaluate the administration and pattern of vancomycin antibiotic use in the Payambar-e-Azam Hospital of Bandar Abbas.

The present study was a retrospective descriptive study in the 2017 year. Patients treated with vancomycin during one year were selected by reviewing the information of patients admitted to the Payambar-e-Azam Hospital of Bandar Abbas. Then, referring to the records of these patients in hospital medical records, the required information was extracted. The information was then reviewed by an infectious disease specialist according to the Infectious Diseases Society of America (IDSA) and Defined Daily Dose (DDD) guidelines.

In this study, 189 patients receiving vancomycin antibiotics in different wards of the Payambar-e-Azam Hospital of Bandar Abbas were evaluated. Of the patients studied, 49 (26%) received vancomycin in the first line of treatment. 170 (90%) were prescribed antibiotics based on experience and 19 (10%) on antibiogram testing. Among the recipients of vancomycin antibiotics, antibiotic use for 92(48/7%) patients was based on a defined daily dose (DDD).

In the present study, about half of the prescribed vancomycin was administered according to DDD guidelines, but most of the treatments are experimental without regard to antibiogram and culture results.
