Economic Examination of Cefoperazone Therapy

Medical records of 1137 patients from 35 hospitals were reviewed to examine the total cost of care for patients receiving cefoperazone as initial therapy compared to a control group receiving alternative agents. The direct costs of care measurable through a retrospective review of patient records were examined, including the cost of antibiotic acquisition, drug administration, laboratory testing, and room and board. Results of a regression analysis show that cefoperazone as initial therapy is associated with lower costs for all factors studied except acquisition cost. Antibiotic acquisition averaged $24 per patient mora for the cefoperazone group (p < 0.01). However, for cefoperazone patients drug administration was $63 less (p <0.0001), laboratory testing costs averaged $9 less (p = 0.22), and costs associated with room and board charges were $80 less (p = 0.40). Total costs averaged $3073 per cefoperazone patient and $3228 per control patient (p = 0.20). These data suggest that the previously accepted definitions of antimicrobial costs (i.e., cost per gram, cost per dose, cost per day) may no longer be adequate in this era of cost containment. In order to make sound clinical decisions with lowest total costs, practitioners should identify how and where costs are incurred.
