The antibiotic support team--a successful educational approach to antibiotic stewardship

Abstract

The efficacy of an antibiotic support team (AST) has been demonstrated in both large teaching hospitals and smaller community hospitals. The usefulness of an AST in a medium-sized military hospital was investigated in the present study. Patients at least 18 years old hospitalized at the David Grant USAF Medical Center (DGMC) and receiving > or =1 of 17 specified antibiotics for > or =3 consecutive days were randomized to an educational intervention group or control group. Primary endpoints included antibiotic defined daily dose (DDD) per patient treatment course and days of antibiotic therapy (DOT) per patient. Fifty-two patients were analyzed from March to August 2006. DDD per patient treatment course was significantly lower in the intervention group, (6.7 +/- 7.6 vs. 12.9 +/- 16.3, p = 0.05). A trend toward fewer DOT per patient was seen in the intervention vs. control group. Implementation of an AST decreased the intensity of exposure to antibiotics.
