Variation in obstetric interventions by midwife.

Area of Science:

• Obstetrics and Gynecology
• Midwifery Practice
• Healthcare Quality Improvement

Background:

• Significant variation exists in rates of birth interventions such as cesarean sections and instrumental deliveries.
• Understanding the factors contributing to this variation is crucial for improving obstetric care and patient outcomes.

Purpose of the Study:

• To investigate the variation in birth interventions among midwives in a Finnish hospital.
• To explore potential explanations for the observed differences in intervention rates, beyond patient selection.

Main Methods:

• Retrospective analysis of 2,135 births attended by 25 midwives in a single Finnish hospital.
• Examination of cesarean section rates, instrumental delivery rates, and characteristics of mothers and infants, including rates of vaginal breech presentations.

Main Results:

• Cesarean section rates varied from 0% to 18% across midwives.
• Instrumental delivery rates ranged from 0% to 8%.
• Patient characteristics and breech birth rates did not fully explain the low cesarean section rates observed in some cases.

Conclusions:

• Midwife-specific factors, including skills, attitudes, and established routines, likely contribute significantly to the observed variation in birth interventions.
• Further research into midwife practice variations can inform best practices and reduce unnecessary interventions.
