Postpartum Hemorrhage Prevention Quality Improvement Initiatives and Blood Transfusion Utilization [ID: 1378079

Abstract

INTRODUCTION: The universal implementation of active management of the third stage of labor, quantitative assessment of blood loss, and hemorrhage risk assessment on admission is recommended to reduce the incidence and morbidity of postpartum hemorrhage. We evaluated the effect of these quality improvement (QI) initiatives, in addition to an active management protocol for iron deficiency anemia antepartum, on the use of blood transfusion during delivery hospitalization. METHODS: We obtained blood transfusion data for the obstetric service at a tertiary care university hospital from January 1, 2017 to July 13, 2022, as well as data for every delivery during that time period (N=11,101). Institutional review board approval was obtained for the study. Patients whose transfusions were administered for nonobstetric indications were excluded. We compared the frequency of blood transfusions and number of units transfused per patient before and after the implementation of QI initiatives. RESULTS: There was a significant downward trend in the frequency of blood transfusions (P=.003) and the number of units transfused per patient (P=.000006) during the study period. The transfusion rate was 3.3% in the year prior to any intervention and 1.78% after implementation of all QI initiatives. No differences were observed in the characteristics of the patient population relevant to hemorrhage risk during the study period. CONCLUSION: This study provides evidence that in addition to reducing postpartum hemorrhage and its morbidity, these QI initiatives also help reduce blood transfusion utilization.
