Quality Improvement Program for the Management of Postpartum Hemorrhage After Vaginal Delivery: Protocol for A Matched-Pair, Cluster-Randomized Controlled Trial

Postpartum hemorrhage is the primary cause threatening the life safety of pregnant women in the world and China, and also the main cause of hysterectomy for women giving birth. The management of postpartum hemorrhage necessitates a coordinated multidisciplinary approach but limited available data on this issue. This program aims to evaluate the effectiveness and acceptability of the integrated strategies, on postpartum hemorrhage after vaginal delivery and relevant clinical practice, in response to the increasing incidence of postpartum hemorrhage and its long-standing threaten to the life safety of pregnant women.

A matched-pair, cluster-randomized controlled trial will be conducted among 50 maternity hospitals with at least 500 vaginal deliveries annually from five provinces in China. Recruited hospitals will be randomly assigned in a 1:1 ratio to either the experimental or comparison arms. All hospitals will receive general interventions, including: recommendation for implementing quality improvement programs to reduce vaginal delivery complications; trainings on obstetric quality management and clinical skills (3 times a year); and monitoring postpartum hemorrhage rate every month. The hospitals in the experimental group will additionally implement integrated improvement strategies which include postpartum hemorrhage risk screening, hierarchical management and preparedness, rescue recording, and case review. The primary outcome is the rate of postpartum hemorrhage, and the secondary outcomes include rate of consequent adverse outcomes, adherence to all known best practices, and staff acceptability to the interventions. These outcomes will be measured and compared between the experimental and control groups. Both intention-to-treat and per-protocol analyses will be performed.
