Abstract:
Objective:To construct an evaluation index system for medical digital subtraction angiography(DSA)equipment in hospitals,and to provide support and reference for the procurement,maintenance and care of hospital equipment.Methods:The DSA equipment evaluation index system was established by Delphi method by using online and offline questionnaire surveys,focus interviews and expert consultations,and the weight of each index of the equipment evaluation was determined by analytic hierarchy process(AHP).Results:The constructed evaluation index system included 5 primary indicators and 26 second-level indicators of system and technical performance,software and safety,machine quality,after-sales service and supplier qualification.The weights of the 5 primary indicators were 0.2954,0.2359,0.2037,0.2072 and 0.0557,respectively.The top 3 weights of the second-level indicators combinations from large to small were accuracy and stability(0.1180),startup rate and failure rate(0.1058)and equipment repair time(0.0804).After the application of the evaluation index system for after-sales service selection,the after-sales service response time was shortened from the average 48.6 h before application to 12.09 h,the response time was shortened by 75.12%,and the service satisfaction of clinical departments with equipment manufacturers was increased from 74.98%before application to 97.37%.Conclusion:The DSA equipment evaluation index system based on Delphi method and AHP can transform subjective evaluation indicators into objective and quantified indicators,which can standardize the formulation of DSA equipment bidding evaluation measures for clinical departments in hospitals,and provide scientific theoretical support for hospital equipment procurement and maintenance.
