Impact of a Multifaceted Quality Improvement Initiative Aimed at Reducing Primary Cesarean Delivery Rates.

Area of Science:

• Obstetrics and Gynecology
• Healthcare Quality Improvement
• Public Health

Background:

• Rising cesarean delivery (CD) rates present a significant public health challenge.
• The optimal strategy for safely reducing CD rates, particularly for nulliparous, term, singleton, vertex (NTSV) births, remains unclear.
• This study addresses the need for effective interventions in an urban, academic, safety-net hospital setting.

Purpose of the Study:

• To evaluate the impact of a comprehensive quality improvement (QI) initiative on the institutional NTSV CD rate.
• To determine if multifaceted strategies can reverse the increasing trend of NTSV CDs.
• To assess changes in maternal and neonatal complications associated with NTSV CDs post-intervention.

Main Methods:

• Implementation of a biweekly interdisciplinary educational meeting for NTSV CD case review and audit.
• Introduction of an educational bulletin, NTSV scorecards, labor position training, and guideline adherence promotion.
• Logistic regression and interrupted time series analysis to model NTSV CD rates and trends pre- and post-intervention.

Main Results:

• A significant reversal of the increasing NTSV CD trend was observed post-intervention, with rates decreasing from 32.9% to 26.3% within 12 months.
• Interrupted time series analysis revealed a significant change in trend from +2.63% per quarter pre-intervention to -3.78% per quarter post-intervention (p < 0.001).
• Maternal and neonatal complication rates remained comparable between the pre- and post-intervention periods for NTSV CDs.

Conclusions:

• Multifaceted QI strategies, particularly those incorporating interactive case review meetings, can effectively change clinical practice.
• This approach offers a feasible and successful method for reducing institutional NTSV CD rates.
• The findings support the broader applicability of such QI initiatives in obstetric settings.
