Abstract:

Objective     To analyze the potential factors affecting indicators of medical quality, to synthetically evaluate the medical quality, and to explore the change of the medical quality in different stages. Methods     With the SPSS 16.0, we analyzed 14 quality indicators by factor analysis from Jan 2007 to Dec 2008, including the number of outpatients, the number of discharges, number of operations, rate of bed utilization, frequency of bed rotation, length of hospital stay, rate of cure and improvement, case fatality rate, coincidence rate of admission and discharge diagnosises, coincidence rate of pathological and clinical diagnosises, coincidence rate of preoperative and postoperative diagnosises, hospital complication rate, mean hospitalization cost, and grade A healing rate of aseptic operation. Results     Three common factors were extracted: the quantitative and qualitative factor, medical level factor, and complication factor. The cumulative contribution rate of the 3 factors was 75.04%. The synthetic factor scores were ascending over the same stages of the two years. Conclusion     The quantitative and qualitative factor, medical level factor and complication factor are the potential affecting factors, and synthetic factor scores can provide evidence for synthetic evaluation on hospital medical quality.
