Drug use evaluation of etamsylate based on weighted TOPSIS method / 药物流行病学杂志

ABSTRACT

Objective To establish drug use evaluation(DUE)standard of etamsylate and to evaluate the use of etamsylate by weighted superior and inferior solution distance(TOPSIS)method,so as to provide a basis for promoting its clinical rational use.Methods Based on the instructions of etamsylate for injection,the DUE criteria of etamsylate were established according to the relevant guidelines of hemostasis at home and abroad,evidence-based literature and expert consultation.The weighted TOPSIS method based on the attribute hierarchy model was used to evaluate the utilization of etamsylate in Beijing Beiya Orthopaedic Hospital.Results Among the 119 cases,2 cases(1.68%)were with the relative closeness degree between each case and the optimal regimen(Ci)no less than 0.8,which was evaluated as reasonable;70 cases(58.82%)were with the Ci ranging between 0.8 and 0.6,which was evaluated as basically reasonable;47 cases(39.50%)were with the Ci less than 60%,which was evaluated as unreasonable.The top three unreasonable rates were dose and frequency(66.39%),configuration method(49.58%),and drug interaction(24.37%).Conclusion The method of DUE of etamsylate based on weighted TOPSIS method can synthesize several evaluation indexes,and the evaluation method is simple and flexible.The rational rate of use of etamsylate in this hospital is low,especially there are problems in configuration method,administration dose and frequency,drug interaction,treatment course and so on,and the management still needs to be strengthened.
