Summary
The Robson 10 group classification system (RTGCS) helps analyze cesarean section (CS) rates. Groups 1, 2, 5, and 10 were the largest contributors to the overall CS rate, suggesting targeted interventions could reduce cesarean births.
Area of Science:
- Obstetrics and Gynecology
- Public Health
- Maternal Health
Background:
- The World Health Organization (WHO) proposed the Robson 10 group classification system (RTGCS) as a global standard for monitoring cesarean section (CS) rates.
- The RTGCS is a reproducible and clinically relevant system for assessing CS rates prospectively.
Purpose of the Study:
- To analyze cesarean section rates using the RTGCS over a three-year period.
- To identify the primary contributing groups to the overall CS rate.
Main Methods:
- A retrospective review of delivery data from 2014-2016 in a Portuguese tertiary hospital.
- Classification of all deliveries according to the RTGCS criteria.
- Analysis of CS rates within each Robson group.
Main Results:
- Data from 6,369 deliveries were analyzed.
- Groups 1, 2, and 3 constituted 67.7% of the obstetric population.
- The overall CS rate was 25%, with Groups 1, 2, 5, and 10 accounting for 74.2% of all CS deliveries.
Conclusions:
- As anticipated, Robson Groups 1, 2, 5, and 10 were the major contributors to the overall CS rate.
- Strategies to increase vaginal birth rates in these specific groups, particularly Groups 2 and 5, may effectively reduce the overall CS rate.
