Objective:
Obstetric hemorrhage is a leading cause of morbidity and mortality. We sought to assess whether institution of a postpartum hemorrhage (PPH) bundle could improve maternal morbidity in our population.
Study Design:
Preintervention data (PRE) was collected on all deliveries at Hospital of the University of Pennsylvania between October 15, 2013 and December 15, 2013. A two-pronged, multidisciplinary educational and procedural intervention related to PPH was instituted from March 2015 to June 2015. Postintervention data (POST) was collected on all deliveries from October 20, 2015 to December 20, 2015.
Results:
Note that 592 of 626 (95%) PRE and 583 of 613 (95%) POST deliveries were included. The rates of PPH by estimated blood loss (EBL) ≥ 1,000 mL and by 3 g hemoglobin drop were not significantly different from PRE to POST (9.0% versus 12.2%, p = 0.07 and 10.5% versus 13.5%, p = 0.10, respectively). There was no significant change in transfusion rate (3.4% versus 5.1%, p = 0.13). Use of uterotonics was reduced from 9.8 to 6.3% from PRE to POST (p = 0.03).
Conclusion:
While institution of a PPH bundle is designed to improve the morbidity of PPH, our data demonstrate that it cannot be expected to do so within 6 months of implementation. Further studies will need to assess the long-term effects of such a resource-intensive protocol, including perceptions of improved safety by all providers, nurses, and staff.
