Disentangling Safety Culture's Role in Reducing Cesarean Overuse: Creating a Revised Labor Culture Survey

Area of Science:

• Healthcare Management
• Patient Safety
• Obstetrics

Background:

• Cesarean delivery overuse remains a significant concern in maternity care.
• Understanding factors influencing cesarean rates is crucial for quality improvement.

Purpose of the Study:

• To assess the relationship between patient safety culture and the overuse of cesarean deliveries.
• To identify specific cultural elements within maternity units that impact cesarean rates.

Main Methods:

• A cross-sectional observational study was conducted in Michigan maternity care hospitals.
• Individual clinician survey data were combined with hospital characteristics.
• Multivariate Poisson regression and factor analysis were used to analyze data from 3091 clinicians across 54 hospitals.

Main Results:

• A new scale, "Unit Norms," encompassing vaginal birth microculture and safety culture, was developed.
• Safety culture showed an association with reduced cesarean rates (IRR 0.86).
• Vaginal birth microculture was the strongest predictor of lower cesarean rates (IRR 0.84).

Conclusions:

• While vaginal birth microculture is the primary driver in reducing cesarean overuse, safety culture elements are also associated with lower rates.
• Characteristics of safety culture, such as teamwork, psychological safety, and communication, are important.
• Measuring these cultural aspects can inform broader quality and safety initiatives in hospitals.
