title: Blood Ordering Strategies in the Armed Forces - A Proposal.
abstract: Over ordering blood is a common practice in medicine. This can be corrected by a simple means of changing the blood ordering pattern. A retrospective study was carried out in a tertiary care hospital of Armed Forces for a three year period to study the blood ordering strategies in the hospital. The total units demanded and the corresponding units issued were estimated. Thereafter, transfusion probability and ratio of units cross-matched to actual units transfused (C/T ratio) was calculated. In this study, using Mead's criterion, transfusion probability and C/T ratio, transfusion guidelines for all cases requiring transfusion is proposed. The study also identifies the common cases where 'Type and Screen' (T&S) procedure could be introduced in cases where the transfusion probability is low. The other group where transfusion probability is high, a maximum surgical blood ordering schedule (MSBOS) has been determined to identify the number of units to be cross-matched and kept ready before the procedure. The implementation of this proposal will avoid over-ordering of blood and will promote maximum utilization.
