Abstract: 【Abstract】Purpose To construct a system for the evaluation of useless hemodialysis machines and to improve a decision- making and technological process for the disposal of useless hemodialysis machines. Method Taking the use of hemodialysis machines in Baoji Central Hospital as an example, an evaluation system for obsolescent hemodialysis machines was established by using the analytical hierarchy process (AHP). The weight of all indicators was determined by using the Delphi method. The evaluation criteria were then developed. Total evaluation score of the equipment was calculated, and disposal of the equipment was conducted in sections. Result A total of 34 hemodialysis machines in our hospital were evaluated. Four units were approved to be scrapped, consistent with the content reported by the department. Six sets were ready to be scrapped; the configuration benefit was maximized by changing the functional parameters and use attributes of the equipment. There were 5 sets in normal use; their preventive maintenance needed to be enhanced. There were 18 sets of equipment in better status; daily maintenance is required for their normal performances. Conclusion The application of this evaluation system resolved the problems that were merely formal and unable to be quantified in the evaluation process of useless hemodialysis machines. Objective, systematic and intuitive
evaluation of scrapping promotes and guides the whole life cycle management and quality control of the medical equipment.
