Antibiotic utilization at the university hospital after introducing an antibiotic policy.
OBJECTIVE
Antibiotic formulary restrictions are among the most popular methods to control antibiotic utilization in hospitals. The aim of the present survey was to investigate the influence of "reserve antibiotic" on antimicrobial utilization at the University Hospital Center (UHC) Rijeka.


METHODS
At the UHC Rijeka, reserve antibiotic was implemented in July 1997. The antimicrobial drug consumption was monitored 6 months prior to and 6 months after the introduction of the method. Antimicrobial consumption was measured in defined daily doses (DDDs) among the major clinics.


RESULTS
Reserve antibiotic has led to a decrease in total antibiotic consumption at the UHC Rijeka (45.9 DDDs/100 bed days vs 32.9 DDDs/100 bed days). Antibiotic utilization decreased in the second semester at most clinics: at the Clinic for Infectious Diseases 41%, at the Anesthesiology and Intensive Care Unit 30%, at the Clinic for Internal Medicine 18% and at the Surgical Clinic 12%. At the Clinic for Gynecology and Obstetrics, the antibiotic utilization remained the same, while at the Pediatric Clinic an increase of 28% in antibiotic utilization was noted.


CONCLUSIONS
Our study indicates that restriction of usage of some antibacterial agents is a successful method to decrease antibiotic consumption and a way to bring cost savings and helps prevent emergence of resistant microorganisms in hospitals. To improve antimicrobial prescribing, additional methods such as education are required.
