Abstract:
【Objective】 To establish scrap indicators for key equipment in blood screening laboratory of blood centers and quantitatively assess the running status of key equipment, so as to provide a scientific method for equipment scrap. 【Methods】 Through the literature review and Delphi method, the scrap indicators of key equipment in blood screening laboratories were established in terms of applicability, economy and advancement of the equipment. The weights of relevant indicators were calculated by analysis hierarchy process (AHP), and the quantitative assessment model of equipment scrap priority was established according to the indicators and its weight. The equipment running data from January 2020 to December 2020 of Laboratory Department were collected and analyzed using the model, and its accuracy was verified based on experience. 【Results】 Thirteen second-level scrap indicators were established, and the weights of the three first-level indexes of applicability, economy and advancement were 0.582, 0.114 and 0.306, respectively. Among the total 30 key equipment, the model score of 4 equipment was less than 0.5, and the running status after manually checking met the scrap standard. 【Conclusion】 The model can accurately assess the scrap priority of key equipment and facilitate the procurement budget and scrapping identification in advance, which can avoid the waste of resources and ensure safe, efficient and orderly laboratory work.
