Justification of blood requisition: A review in a tertiary care trauma center in Eastern India

Abstract

Background: The purpose of this study is to compile and review the blood utilization in various surgical departments in a tertiary care trauma center. To monitor and improve transfusion practices, analysis of effective usage of blood and its components is necessary. Methods: A retrospective cross-sectional study was done in the department of pathology in our center for a period of 6 months. Data from blood requisition forms, transfusion forms, and issue register were compiled and reviewed. The number of units requested cross-matched and transfused for every patient was collected. Statistical Analysis: The data were entered in SPSS version 20 and analyzed through the calculation of blood transfusion parameters: (i) cross-match to transfusion ratio (C/T), (ii) transfusion probability (T%), and (iii) transfusion index (TI). Results: 2724 units of blood was cross-matched and 2108 units of blood was transfused. The overall C/T ratio calculated was 1.29, TI was 0.77, and T% was 88.2%. All these figures are under the desirable range. Conclusion: The study concluded that though the trauma center in our hospital meets the parameters required for blood transfusion, yet the departments requiring blood should critically analyze the blood requisitions to minimize the blood bank load and cost.
