Platelet audit: Assessment and utilization of this precious resource from a tertiary care hospital
Abstract
Background: To assess the appropriate utilization of platelet transfusions [random donor platelets (RDP) and single donor platelets (SDP)]; a six-month retrospective audit was carried out in a tertiary care hospital. Materials and Methods: A six-month retrospective platelet audit was carried out from May to October 2005 to estimate its preparation, appropriate utilization and wastage rate. Patient′s demographics, transfusion triggers and episodes and ABO and Rh (D) group specific or non-group specific transfusions were also assessed. Results: About 5525 units of platelets [PRP-PC, 3,813 (69%); BC-PC, 983 (17.8%); PRP, 648 (11.7%) and SDP 81 (1.5%)] were prepared and transfused to 853 patients (RDP to 814 patients and SDP to 39 patients) in 2,093 transfusion episodes. Adult and pediatric hemato-oncology were the main user specialties utilizing 39.1 and 87.6% of the RDPs and SDPs prepared. Of the patients receiving RDPs, 95% were transfused ABO and Rh (D) group specific platelets whereas 100% SDPs transfusions were of group specific platelets. 88% of prophylactic platelet transfusions were appropriate as per the recommended BCSH guidelines. However, 12% of the prophylactic platelets were transfused inappropriately in cardiopulmonary bypass (CPB) surgeries with normal platelet counts and no evidence of bleeding related to platelets. Out of 5,444 RDPs prepared 1,585 (29.11%) units were not utilized. Conclusions: Regular audit of blood and blood components is a must so that necessary remedial measures can be taken to maximize appropriate and judicious utilization of each component.
