Evidence-based strategies for reducing cesarean section rates: a meta-analysis

Area of Science:

• Obstetrics and Gynecology
• Public Health
• Health Services Research

Background:

• Canada's cesarean section rate reached a high of 22.5% in 2002, posing potential maternal and neonatal risks.
• Clinical practice guidelines offer a means to reduce cesarean section rates, but implementation remains a challenge.

Purpose of the Study:

• To assess the effectiveness of interventions aimed at reducing cesarean section rates.
• To evaluate the impact of cesarean section rate reduction on maternal and perinatal mortality and morbidity.

Main Methods:

• A meta-analysis was conducted using data from the Cochrane Library, EMBASE, and MEDLINE (January 1990 to June 2005).
• Included studies involved rigorous evaluation of strategies to reduce overall cesarean section rates.
• Study designs evaluated included randomized controlled trials, controlled before-and-after studies, and interrupted time series studies.

Main Results:

• A significant reduction in cesarean section rates was observed (pooled RR = 0.81).
• Effective interventions included audit and feedback, quality improvement, and multifaceted strategies.
• Identifying barriers to change enhanced intervention effectiveness; no significant differences in maternal/perinatal mortality or morbidity were found.

Conclusions:

• Interventions involving healthcare workers in practice analysis and modification can safely reduce cesarean section rates.
• Multifaceted strategies based on audit and feedback are advised for improving clinical practice.
• Identifying barriers to change is crucial for successful implementation and reduction of cesarean section rates.
