Abstract: Objective To construct an evaluation model of clinical blood transfusion records based on Cov-AHP-fuzzy comprehensive evaluation method. Methods An index system for the quality evaluation of clinical blood transfusion records was established by the professional scoring method. The weight of each index was determined by covariance-analytic hierarchy process (Cov-AHP). Finally, 100 clinical blood transfusion records were collected and evaluated to verify the rationality of the model. Results The evaluation index system was established according to four dimensions, including blood transfusion application process, blood transfusion document, blood transfusion evaluation and blood transfusion nursing. The weight of each index was determined. The evaluation result of the 100 records was consistant with the normal distribution. Conclusion This evaluation model can more scientifically and rationally evaluate the clinical blood transfusion records, and strengthen doctors' attention to clinical blood transfusion. In addition, the model can also supervise the clinical blood transfusion chain, improve haemovigilance system, and effectively reduce the occurrence of transfusion adverse events.
