Abstract:Objective：Based on the medical device management system, this paper evaluates the maintenance costs, economic benefits and service satisfaction of the monitor at different purchase prices, which can guide the choice of the purchase price of equipments. Methods：Three kinds of Monitors，purchased at different prices in the same year（A=18，000 yuan/station，23，000 yuan/station，41，000 yuan/station），are monitored by the medical device management software introduced by the hospital. All devices are operated and maintained under the same condition for three years. The maintenance times，maintenance costs，economic benefits and service satisfaction of the three kinds of prices monitors are compared. Results：The maintenance times of type A monitor is significantly higher than those of the latter two, and the difference is statistically significant. There is no significant difference in maintenance times between type B and type C. The maintenance costs of type A is significantly higher than those of the latter two types，and the maintenance costs of type B is slightly lower than type C，but the difference is not statistically significant. The C type monitor produces the lowest economic benefits when considering the incoming prices，maintenance costs，and depreciation costs. Conclusion：Price is not the main factor to determine the introduction of a certain of medical device. Only by lowering the purchase price within a reasonable range can we really save costs.
