Inpatient management protocols to reduce health care costs.

A group of 12 internists, members of a university-affiliated hospital, designed and implemented protocols for the general inpatient management of four medical problems (chest pain, stroke, pneumonia, and upper gastrointestinal hemorrhage). Hospital charges for the 63 cases were compared with charges generated by 64 controls who had been patients admitted to the same physicians with the same diagnoses during the same period of the preceding year, before the project was begun. A group of nonparticipating internists was similarly evaluated during the two time periods to control for changes in practice patterns extraneous to the intervention. Adjustment was made for inflation (6%) and differences in case mix. The program resulted in a 15% reduction in total average charge generated by the cases. Sizeable reductions were achieved in utilization of EKGs (34.8%), x-rays (15.4%), laboratory testing (20.4%), and drugs (11.4%). Given the prevailing attitude that health care costs are too high and that many services are unnecessary, the benefit of altering physician behavior by using standards established by them for themselves could be substantial, especially with the threat of more restrictive and less sympathetic modes of controlling costs.
