Excessive requests for cross matching blood which is more than the blood required for transfusion are usually based on worst case assumptions leading to overestimation of blood usage. We investigated the blood ordering pattern and transfusion practices so as to incorporate a blood ordering schedule for streamlining the use of blood in various hospital departments.
The study was conducted over a period of 19 months in a 350 bedded tertiary teaching hospital. Source of data was blood bank requisition forms and blood bank registers of patients who underwent elective or emergency procedures in the hospital, for which blood was ordered. Data were entered in MS Excel and analysed using SPSS version 20.
The blood bank was requested to prepare 10,594 units of blood for 2556 patients. The blood utilised was 16.04% of total cross matched blood, leaving 83.9% of units cross matched but not transfused to patient for whom it was prepared, i.e., wasted. The surgery department had the highest number of units cross matched and transfused. The least number of units cross matched and wasted due to non-transfusion were from the Department of Oncology.
The current deficiency of explicit maximum blood order schedule in our hospital is the major factor responsible for high cross match: transfusion ratio. Therefore, a maximal surgical blood order schedule has been suggested to the hospital transfusion committee to implement maximum surgical blood order schedules for selected procedures.
对交叉配血的过量需求（超过输血所需血量）通常基于最坏情况假设，导致对用血的高估。我们调查了用血订单模式和输血实践，以便制定一个用血订单计划，以优化各医院科室的用血情况。
本研究在一家拥有350张床位的三级教学医院进行，为期19个月。数据来源是医院中接受择期或急诊手术且已预订血液的患者的血库申请表和血库登记册。数据录入MS Excel并使用SPSS 20版进行分析。
血库被要求为2556名患者准备10594单位血液。实际使用的血液占交叉配血总量的16.04%，即有83.9%的交叉配血单位未输给为之准备的患者，造成了浪费。外科的交叉配血和输血单位数量最多。肿瘤内科交叉配血且因未输血而浪费的单位数量最少。
我院目前缺乏明确的最大用血订单计划是导致高交叉配血与输血比例的主要因素。因此，已向医院输血委员会建议制定最大手术用血订单计划，以便对选定手术实施最大手术用血订单计划。
