Abstract

Background: The management of red blood cell inventory in hospital's blood bank is crucial. The Australian Red Cross Blood Service developed a RBC safety stock calculation method (abbreviated as the 'Australian formula'). In this study, we applied this method to four Korean hospitals to calculate the safe RBC stock level. Methods: The hospitals included in this study were three tertiary teaching hospitals and one teaching hospital. The number of hospital beds in these hospitals were 1093, 1330, 1400, and 854, respectively. The data were collected from the Korea Blood Inventory Monitoring System of Centers for Disease Control & Prevention. The target/minimal/maximal RBC inventory levels and inventory days (inventory level/average daily usage) by ABO blood types were calculated using the daily red cell transfusion, wastage, and supply data between May and October 2016. Results: The enrolled hospitals showed different levels for the target/minimal/maximal RBC inventory according to each blood group. The average of RBC inventory days in the four hospitals was 4.2 days. For each blood group, RBC inventory days were 3.2~4.4 days for O blood group type, 3.5~4.7 days for A blood group, 3.9~4.5 days for B blood group, and 3.9~5.5 days for AB blood group. Conclusion: Because the optimal RBC inventory levels are different depending on the hospital characteristics and the ABO blood group, it is necessary to set the RBC inventory levels for each hospital distinctly. The data obtained in this study will help manage blood product inventory in various hospital blood banks. Blood safety stock calculation;Blood inventory management;Red blood cell;

배경: 의료기관 혈액은행의 혈액제제 재고관리는 효율적인 적혈구제제의 재고관리를 위해 필수적이다. 호주 NIMF의 적십자사 혈액 서비스에서는 적혈구제제 적정 재고량을 계산하기 위한 공식을 개발하였다. 저자들은 호주 NIMF의 적혈구제제의 적정 재고량 산정공식을 4개 국내 의료기관에 적용해보고 그 경험을 보고하고자 한다. 방법: 대상 의료기관에는 3개의 상급종합병원과 1개의 종합병원이 포함되었고, 병상 수는 각각 1,093, 1,330, 1,440 및 854이었다. 질병관리본부 혈액수급관리 표본감시체계를 통해 필요한 자료를 수집하였고, 2016년 5월에서 10월까지 6개월 간의 ABO혈액형별 적혈구제제 수혈량, 폐기량, 공급량 자료를 이용하여 목표/최소/최대 적혈구재고량과 이를 일별 적혈구제제 사용량으로 나눈 목표/최소/최대 적혈구제제 재고일을 계산하였다. 결과: 각 혈액형별 목표/최소/최대 적혈구재고량은 각 의료기관에 따라 매우 다양하였다. 의료기관의 적혈구제제 재고일은 평균 4.2일이었고, ABO 혈액형 별로 O형 3.2~4.4일, A형 3.5~4.7일, B형 3.9~4.5일, AB형 3.9~5.5일이었다. 결론: 적혈구제제의 적정 재고량은 의료기관의 특성과 ABO 혈액형에 따라 차이를 보이므로 각 의료기관에 따라 설정해야 한다. 이 연구는 향후 의료기관 혈액은행의 혈액제제 재고관리에 도움이 될 것으로 생각된다.
