Construction and application of a clinical benefit evaluation model of medical equipment based on combination weighting of game theory with cloud model
Objective:To construct a clinical benefit evaluation model of medical equipment based on the combination weighting of game theory with cloud model,so as to improve the clinical service capability and operational quality of medical equipment. Methods:The game theory,combination weighting and cloud model were used to scientifically empower and comprehensively evaluate 13 clinical benefit evaluation indexes from 3 dimensions:direct input,direct output. and indirect benefits of medical equipment,and to develop corresponding equipment management strategies.. 47 large medical equipment in clinical use at Taizhou People's Hospital from 2022 to 2023 were selected,and the large medical equipment used in 2022 was subjected to subjective evaluation management. The equipment used in 2023 adopts a medical device clinical benefit evaluation model (referred to as model evaluation management) of game theory combination weighting and cloud model to carry out clinical benefit evaluation and management of the equipment. The clinical benefit,operation quality and management level of the two management methods were compared. Results:The effective management rate of medical equipment using the model evaluation management method was 63.83％(30/47),which was higher than that using the subjective evaluation management method,and the difference was statistically significant (x2=5.158,P<0.05). The average clinical risk rate,failure rate and detection failure rate of medical equipment using the model evaluation management method were (10.59±3.09)‰,(7.27±3.53)‰ and (12.06±2.43)‰,respectively,all of which were lower than those obtained through the subjective evaluation management method. The differences were statistically significant (Z=3.783,2.748,3.928,P<0.05). The assessment scores of medical equipment use managers on the ability of equipment use,maintenance,repair and planning using the model evaluation management method were (93.38±3.73) points,(94.05±3.14) points,(92.61±3.44) points and (94.88±2.50) points,respectively,which were higher than those obtained through the subjective evaluation management method. The differences were statistically significant (Z=2.718,3.036,3.039,3.929,P<0.05). Conclusion:The application of the clinical benefit evaluation model of medical equipment,which based on the game theory combination weighting and cloud model,can accurately evaluate the clinical benefit level of medical equipment,and improve the operation quality of the equipment,and enhance the management level of equipment.
