The frontier field of hospital information system is the application of cybernetics and systems engineering methods with the help of various computer applications to establish medical quality evaluation system and medical quality control system.
Medical quality evaluation system its main contents include: ① medical quality evaluation. With the type of cases, medical referrals, medical errors and accidents, diagnostic compliance rate, the average number of hospital days, the average medical cost and other parameters as the basis for evaluation, the calculation of medical quality of the comprehensive evaluation of the index to evaluate the quality of medical care. ②Nursing quality evaluation. Basic nursing care, operating techniques, psychological care, ward management, filling out nursing forms, implementation of rules and regulations, etc. as the evaluation conditions and weights, the establishment of mathematical models, processed by the computer to make the evaluation. (iii) Evaluation of hospital work efficiency. Taking the average working days of beds, the actual bed utilization rate, the average number of turnover of beds and the average number of days of hospitalization of discharged patients as the parameters, and stipulating the weights, a comprehensive evaluation index is established to evaluate the work efficiency. ④ Medical staff work quality evaluation. The fuzzy comprehensive judgment method is used to establish a mathematical model to calculate the relative score of each person's work evaluation with a fuzzy matrix.
