Summary
Caesarean section rates varied widely among 15 obstetricians for low-risk births. This variation was not linked to patient outcomes, suggesting other factors influence surgical delivery decisions.
Area of Science:
- Obstetrics and Gynecology
- Clinical Epidemiology
Background:
- Caesarean section rates have been increasing globally.
- Variability in surgical intervention rates among clinicians is a significant concern in maternal healthcare.
Purpose of the Study:
- To investigate the variation in Caesarean section rates among obstetricians for low-risk pregnancies.
- To determine if obstetrician-specific Caesarean rates correlate with perinatal outcomes.
Main Methods:
- Retrospective analysis of 5,559 deliveries of nulliparous women with a single cephalic infant weighing at least 2,500g.
- Data collected from one hospital, examining rates across 15 individual obstetricians.
Main Results:
- Significant variation observed in Caesarean section rates among obstetricians, ranging from 5.5% to 20.1% overall.
- No correlation found between individual obstetrician Caesarean rates and perinatal outcomes.
- Differences in rates could not be attributed to institutional, physician, patient, or economic factors.
Conclusions:
- Wide disparities in Caesarean section rates exist among obstetricians even for low-risk pregnancies.
- Perinatal outcomes do not explain the observed variations in surgical intervention.
- Further research is needed to understand the drivers of these differences in clinical practice.
