Computerized approach to active and objective quality control of patient care

Abstract

The paper describes a quality control program based on the principles of clinical methodology and indicators defined by physicians and hospital administrators according to general as well as local needs. The program is supported by a knowledge-based system which can be used in two ways: with on-line helps and hints to ensure effective and efficient medical decisions on a simulated patient for training purposes; and without facilities supporting the user to be used on an on-line setting for performance evaluation. The quality control program includes the evaluation of effectiveness and efficiency of patient care with respect to the overall process, single hypotheses and individual decisions: the evaluation regards the number and reliability of activated hypotheses, costs, time spent, number and appropriateness of investigations. The overall process is recursive, in that the results of each cycle are used by physicians to define new goals and indicants for the next cycle; quality control is active because physicians under evaluation are directly involved in the definition of goals and indicants and in the evaluation of results; evaluation is objective because indicants are predefined, and evaluation criteria are transparent.
