Long-term pharmaceutical cost reduction using a data management system

Cost containment is an important issue in medicine today, and the ability to control costs and maintain quality patient care presents a challenge to practitioners. Educating practitioners about drug costs has been identified as an effective method, but the benefits of education are usually short-lived. To evaluate the role of education in cost control, pharmaceutical use and performance improvement data were analyzed at a tertiary care institution during two time periods. A total of 4,530 anesthesia records and associated performance improvement data from March to June 1993 were analyzed as a baseline. These data were shared with the clinicians of an anesthesia department and used to educate practitioners regarding the costs and use of injectable pharmaceuticals and to identify areas in which cost savings could be achieved. The same information from 10,600 cases during January to October 1996 were compared with the early group. The expenditures for injectable pharmaceuticals to provide anesthesia were decreased by more than $30,000 per month, or $32 per case, without changing the performance indicators that were monitored, and has been maintained for >3 yr. Implications: By using a data management system, the cost for medications to provide anesthesia has been reduced without changing the quality of patient care.
