Research on the comprehensive evaluation of patient satisfaction based on the attribute reduction and AHP

Focusing on the systematicness and validity of the evaluation system of the patient satisfaction, large number of factors impacting the patient satisfaction were considered comprehensively, the analytical method combining the Attribute Reduction in Rough Set with AHP was adopted. First, the evaluation factors were analyzed to establish the evaluation hierarchical model of the patient satisfaction, the indexes were reduced by Attribute Reduction based on the information quantity; then, the significance of attribute was used to determine the index weight; lastly, the total sequence weight of sub-criteria was calculated by AHP method and the comprehensive evaluation value was obtained. This model was used to evaluate and analyze the five hospitals in one area and the validity of this method was tested. This method reduces the amount of calculation, improves the computational efficiency and provides a method of quantitative analysis.
