Hospital organizational context linked to lower cesarean delivery rates

Researchers compared organizational conditions and quality improvement (QI) strategies at 17 hospitals participating in Michigan’s Obstetrics Initiative. The comparative multiple case study included hospitals with more than 1,000 annual births, purposively selected for low or high nulliparous, term, singleton, vertex (NTSV) cesarean delivery rates. Investigators interviewed 110 clinicians and administrators during site visits from February to April 2023, using implementation research frameworks to assess barriers, facilitators, and improvement strategies.

Five hospitals had NTSV cesarean rates of 25% or lower, and 12 had rates of 28% or higher. Fifteen contextual factors—11 hospital conditions and four improvement processes—differentiated the groups. Lower-rate hospitals had more facilitators and fewer barriers, including more supportive leadership, stronger collaboration and learning cultures, and more robust QI planning, engagement, and evaluation. Researchers identified 28 core strategies consistently observed at lower-rate hospitals and nine context-dependent strategies that could address local barriers.

The findings may help maternity units assess local obstacles and tailor cesarean delivery QI efforts. However, this qualitative, purposively sampled comparison establishes associations rather than causal effects or the effectiveness of individual strategies. Its focus on higher-volume hospitals in one statewide collaborative may limit generalizability. The collaborative was funded by Blue Cross Blue Shield of Michigan and Blue Care Network.
