Making sufficient supplies of blood available and sustainable is a challenge faced by all countries. This study aimed to develop an improvement plan for the domestic blood supply and demand monitoring system and the Blood Inventory Monitoring System (BMS) in preparation for the conversion from blood supply and demand monitoring to total monitoring. This study reviewed the current blood supply and demand monitoring system and indicators.
First, as a result of reviewing the overall blood supply and demand monitoring system, it was estimated that three billion won in introduction costs and 860 million won in annual maintenance costs would be required to introduce a new independent computerized system to complement the current BMS. Second, as a result of reviewing the statistics, indicators and reports, new indicators, such as blood inventory ratio and total number of days of blood shortage of total Red Blood Cell (RBC), including Leukocyte Filtered Red Blood Cell (F-RBC), were proposed, and a simplified report format was proposed. Third, the study proposed a method for the full surveillance of the blood supply and demand monitoring system. This study recommended that medical institutions using more than 100 units of RBCs per year be expanded first and then expanded step by step based on the supply of the Korean Red Cross (KRC) rather than having all medical institutions participating simultaneously. Two plans of data registration for full surveillance were proposed. The first plan introduced a real-time monitoring system using a commercial open Application Programming Interface (API), and the step-by-step application period was expected to be about 44-50 months (3.7-4.2 years). As for the budget required, commercial open API purchase costs (about 500 million won) and maintenance costs (80 million won annually + α) were additionally expected. The second plan was to maintain the current BMS registration system, which was expected to take 12-18 months (1-1.5 years) when applied in stages. In addition, it was necessary to prepare a budget for labor and system maintenance costs.
Based on the results of this study, the operation and management system of blood supply and demand monitoring will be reorganized, and detailed operation plans such as budgets, manpower, and system improvements for the conversion to full surveillance will be prepared. In addition, this study should be used as basic data for establishing and promoting policies related to blood supply and demand in the future.
