Reducing the cost of surgical prophylaxis

Abstract

A four-part program was implemented in order to control the rising cost of prophylactic antibiotics: limiting the number of cephalosporins on formulary; prohibiting the use of third- and most second-generation cephalosporins for prophylaxis; using a special order form to designate use as empiric, therapeutic, or prophylactic; and mandatory discontinuance of prophylactic antibiotics after 24 hours. The total cost for administration of prophylactic antibiotics was reduced from an average of $37.35 per case for the six months preceding the start of these restrictive policies to an average of $21.99 per case during the next twelve months. Class I and class II wound-infection rates were 2.0 per cent and 4.9 per cent, respectively, prior to the adoption of the new antibiotic practices. Comparable infection rates were 1.8 per cent and 2.1 per cent, respectively, after this program was initiated. The rising cost of antibiotic prophylaxis can be reduced without adversely affecting wound-infection rates.
