Computer-based patient records and changing physicians' practice patterns.

Abstract

Computer-based patient records (CPRs) have been under development for more than a quarter of a century. In comparison to the traditional paper medical record, they offer a vast improvement in reporting, organizing, and locating clinical information; they can support clinical decision making; and they can be designed to coordinate and manage patient care. Research concerning these three functions is reviewed. Despite their demonstrated benefits, CPRs have met with limited acceptance among physicians. Barriers to their acceptance and ability to change practice behavior are discussed. Empirical studies that have used opinion leaders among physicians to encourage the use of a medical information system and to change practice behavior are reviewed. Finally, suggestions as to how to facilitate the development and adoption of CPRs are outlined.
