Use, misuse, and cost of parenteral cephalosporins at a county hospital.
We reviewed total usage of parenteral cephalosporins at a county hospital during 1978 with regard to appropriateness, pattern of use, and cost. In addition, we determined the impact of replacing cephalothin with cephapirin in the hospital formulary. During the 12-month study 366 patients received 409 courses of parenteral cephalosporins: 167 received cefazolin, 160 received cephapirin, and 35 received a combination of cefazolin and cephapirin. The surgical service prescribed 87% of the cephapirin and 92% of the cefazolin. Parenteral cephalosporins were used 62% of the time for prophylaxis and 38% of the time for therapy. Usage was judged inappropriate in 47% of all courses based on our criteria; 25% of the therapeutic courses were judged inappropriate, compared to 60% of the prophylactic courses. Pharmacy costs of cefazolin used as prophylaxis were more than twice the cost for cephapirin. Cost of a mean therapeutic course for cefazolin was 43% higher than for cephapirin. Antibiotic audits and continued education combined with judicial substitution of therapeutic equivalents should limit the inappropriate use and expense of parenteral cephalosporins for large as well as small hospitals.
