ObjectiveTo explore a strategy for selecting and evaluating the warranty contract of medical equipment.MethodsBased on the operating costs of the two linear accelerators between 2016 and 2019, we obtained the criticality of medical equipment by using the five indicators, including necessity of maintenance, function, risk, importance, and age of medical equipment, selected the warranty strategy by comparing the cost of key components, and adjusted and optimized the warranty strategy based on the economic benefit assessment during the implementation process of warranty contract.ResultsThe criticalities of the two linear accelerators were both 18 points, and it was recommended to purchase warranty service. By comparing the cost of key components, the annual average maintenance cost of the key components of the two accelerators was lower than the annual warranty cost, so we chose the semi-guaranteed contract. Finally, according to the economic benefit accounting and evaluation in the implementation process of the warranty contracts of the two linear accelerators, the linear accelerator 1 remained unchanged, and the linear accelerator 2 was turned from the semi-guaranteed contract into the full insurance contract when we renewed the warranty contract.ConclusionsThe warranty contract selection and evaluation strategy proposed in this paper has certain guiding significance for the choice of strategy of warranty contract. By choosing the appropriate warranty service scope and warranty strategy, and continuous adjusting and optimizing according to the actual performance of the contract, we can effectively guarantee the operational efficiency of medical equipment, and reduce operating costs simultaneously.
ObjectiveTo explore the main failure components related to maintenance cost and downtime of gastrointestinal endoscopy.MethodsThe analytic hierarchy process (AHP) was used to process and analyze the maintenance data of gastrointestinal endoscopy in West China Hospital of Sichuan University from January 2010 to April 2019.ResultsThe results involved 110 gastrointestinal endoscopy, 322 major repairs, 364 minor repairs, and a total of 1 651 failed components, in which the top three components were buttons (380 pieces, 23.02%), the insertion tubes (223 pieces, 13.51%), and lenses (179 pieces, 10.84%). The main failure components causing high maintenance cost and long downtime of major repairs were charge coupled devices (F=849.702, P<0.001; F=9.525, P=0.002) and light guides (F=8.190, P=0.005; F=6.384, P=0.012). The failure components affecting the maintenance cost of minor repair were lenses (F=25.464, P<0.001) and angle steel wires (F=5.652, P=0.018). The failure components prolonging the maintenance time of minor repair were lenses (F=10.384, P=0.001) and electrical interfaces (F=4.816, P=0.029).ConclusionQuantitative analysis of maintenance data is helpful to objectively analyze the main failure components of maintenance cost and downtime.
