AIMS: To determine the utilization of cross-matched packed red blood cell (PRBC) concentrate in children posted for major elective operative procedures. To evaluate the efficacy of a simple preoperative "screening criteria" for ordering preoperative cross-match.
MATERIALS AND METHODS: Data were retrieved from online surgery scheduling system prospectively over a 4-month period (January-April 2022). The number of units cross-matched and those utilized were assessed. A screening criterion was devised in consultation with stakeholders for ordering blood. The utilization of PRBCs was reassessed after implementation of these criteria and reaudited (July-October 2022). A subset analysis of A1 (tunneled catheter placements) and A2 (core pediatric surgical procedures) groups was done to analyze blood utilization.
RESULTS: Initial audit showed poor PRBC utilization with 46 units unused of the 54 cross-matched units, and most of these were from A1 group (3 of 29 units and 5 out of 25 units utilized in A1 and A2 groups, respectively). Reaudit after introducing cutoff criteria showed sharp decline (79.3%) in the number of cross-matched units and the number of units returned (84.6% decrease) in A1 group and the number of units returned unused dropped by 50% in the A2 group. There was visible reversal of indicators of utilization (cross-match to transfusion ratio dropped from 6.75 to 1.73 and TI increased from 0.163 to 0.613), indicating optimal utilization.
CONCLUSION: This pilot audit clearly demonstrates the gap between requisition and utilization of cross-matched PRBCs. Formulating an effective screening criterion avoids unnecessary cross-matching and wastage of resources and maximizes utilization.
