Abstract:
Objective:To assess the values of computed tomography(CT)equipment in whole life cycle and operation status from multi-dimension based on real world data,and to quantify the performance,operation status,and benefit analysis of medical equipment,so as to assist to grasp the operation status of CT equipment for hospital.Methods:Depended on the viewpoint of real-world data,economic benefits,metrology and performance data of 5 pieces of CT equipment,which included type A,type B,type C,type D and type E,used in hospitals in the last 4 years were collected.Type A,type B and type C were all imported CT equipment,and type A and type B were the same model.Both type D and type E were domestic CT equipment.The analytic hierarchy process(AHP)was used to assign the weights of each data,and form effectively multi-dimensional evaluation system.Results:The value of consistency ratio(CR)of the hierarchical weight allocation matrix was 0.042 that was less than 0.1,which met the requirement of consistency test.The scores of the comprehensive values the 5 pieces of CT equipment of type A,type B,type C,type D and type E were respectively 68.10,30.35,39.50,60.99 and 39.76.There was a significant difference between the two pieces of imported CT equipment of type A and type B of the same model in different use environments.The score of type D of domestic CT equipment was higher than those of the type B and type C of imported CT equipment,respectively.Conclusion:Under suitable use environments,domestic CT equipment can replace imported equipment.The AHP method can be used in the assessment of CT equipment value.
