Do family physicians 'prevent' cesarean sections? A Canadian exploration

Area of Science:

• Obstetrics and Gynecology
• Family Medicine
• Public Health Policy

Background:

• Canadian birth trends show a decline in family physician-attended births.
• Cesarean birth rates have concurrently risen across Canadian provinces.
• This shift is particularly notable in provinces with more obstetricians and urban populations.

Purpose of the Study:

• To investigate the relationship between the declining rate of family physician-attended births and the increasing cesarean section rate in Canada.
• To explore the influence of societal, environmental, and interprofessional factors on these trends.

Main Methods:

• Analysis of national birth and cesarean section rates.
• Comparison of perinatal mortality rates across provinces with differing maternity care models.
• Examination of the correlation between obstetrician availability, birth rates, and metropolitan area size.

Main Results:

• Perinatal mortality rates are similar across provinces, irrespective of whether obstetricians or family physicians dominate maternity care.
• The decline in family physician-attended births and rise in cesarean sections appear linked to factors beyond objective quality of care.
• Low-technology, high-continuity care may be as safe or safer for low-risk pregnancies.

Conclusions:

• Societal, environmental, and interprofessional dynamics significantly influence cesarean section rates and the role of family physicians in Canadian maternity care.
• Objective quality of care metrics do not fully explain the observed trends in birth attendance.
• The study questions the universal application of highly interventive care, advocating for evidence-based, lower-intervention approaches for appropriate patient groups.
