Cost and Quality in the Use of Blood Bank Services for Normal Deliveries, Cesarean Sections, and Hysterectomies

Abstract

To reduce costs, preserve blood supplies, and enhance the safety of blood use during emergencies, the Department of Obstetrics and Gynecology and the blood bank at a teaching hospital recommended replacing pre-delivery crossmatch on selected patients with typing and screening for all patients undergoing normal or cesarean section delivery. Using an automated data system, it was shown that 75% and 50% reductions in the ordering of crossmatching for these two groups of patients promptly resulted, endured over a one-year follow-up period, and also spread to include patients undergoing hysterectomy. However, the cost of the increased use of typing and screening outweighed the reduced cost of crossmatching: actual annual costs increased by $11 151. We conclude that test-ordering practices can be changed surprisingly easily if a specific and reasonable policy is advocated by influential clinicians. However, changes in test use can cause unexpected cost increases. Only detailed study of practice patterns can reveal cost consequences for a specific institution.
