Evaluation of the Use of Cefuroxime and Cefuroxime Axetil in an Intravenous—Oral Stepdown Program

Abstract

OBJECTIVE:

To characterize cefuroxime and cefuroxime axetil use under the influence of a parenteral-to-oral (iv—po) stepdown program.

DESIGN:

Open single-center retrospective review.

SETTING:

Tertiary care teaching and referral Canadian hospital with 1100 beds.

PATIENTS:

a random sample of 78 patients receiving cefuroxime was compared with a random sample of 50 patients receiving iv—po cefuroxime stepdown.

RESULTS:

During the first 6 months following formulary introduction, 1535 patients received cefuroxime. Stepdown to any oral antibiotic occurred in 22% of patients. Cefuroxime axetil was used as the stepdown agent in 64% of these cases. In a comparison of nonstepdown courses with stepdown courses, some differences were apparent. Nonstepdown treatment courses were primarily prophylactic, whereas stepdown courses were typically initiated as primary therapy for the 10-day management of respiratory tract infections (p < 0.001). Conversion to oral therapy typically occurred on day 5 of parenteral therapy and continued for 5 days. Stepdown was considered possible in 46% of treatment courses in which this process did not happen. When stepdown did occur, it was considered timely in 64% of cases, unnecessarily delayed in 32%, and premature in 4% of treatment courses. Stepdown did not appear to be associated with a negative impact on patient outcome. Mean ± SD cost of drug therapy per day was less for the stepdown group (US $15.78 ± $5.97) than the nonstepdown group (US $25.47 ± $7.87; p < 0.001).

CONCLUSIONS:

As a result of this study we intend to maintain cefuroxime and cefuroxime axetil on the formulary and continue to judiciously promote the timely conversion to oral therapy.
