Abstract
Introduction
Audit and education are essential pre-requisites in the review and update of blood transfusion practices. Although standard guidelines on appropriate utilization of blood components exists, erroneous use of blood components with no justification still continues. This study evaluates appropriateness of blood transfusion in obstetric settings and identifies key areas requiring educational intervention to improve blood transfusion practice toward the evidence-based at our hospital.
Method
This was a prospective observational study on the analysis of blood transfusion requisition forms for obstetric patients before and after educational intervention, performed in two Phases from September 2011 to August 2012 and October 2012 to September 2013. The appropriateness of blood utilization was assessed against the Royal College of Obstetricians and Gynecologists Guidelines for blood transfusion and Green-Top Guideline no. 47. Data required for the study were obtained from department records and statistical analysis was performed using the SPSS, version 20 (IBM, USA).
Results
The total transfusion episodes were 214 in 51 patients and 181 in 43 patients in Phases 1 and 2, respectively. Fresh frozen plasma was the most misused blood component, next to whole blood in Phase 1. However, appropriate utilization of components, including cryoprecipitate (6.6%), reduction in whole blood (34.5-14.4%) and single unit transfusion (23.3-18.2%) were observed in Phase 2. Inappropriate use of blood components, namely, packed red blood cells and fresh frozen plasma dropped significantly (p < 0.05) from 29.7% to 13.1% and 45.1% to 22.5%, respectively, with the exclusion of platelet concentrate (33.3-20.6%, p-value 0.414).
Conclusion
Audit and targeted education helped in optimizing transfusion practices in the obstetric setting.
