A simple, low-cost computerized minirecord system (minimal essential record) has been in operation at the Johns Hopkins Medical Clinic since mid-1975. The system has three primary components: (a) the Minirecord which contains a listing of problems and medications, plus information about visits to other clinics, (b) an appointment system used to organize materials prior to clinic encounters and assist in the follow-up of high risk special patients, and (c) an encounter data system to prepare reports used for management, quality assurance and training. This paper describes the system’s operation, and reports on its utility and cost.
