Background: The use of caesarean section (CS) has increased worldwide, even in India, where the all-India CS rate is reported to be 21.5% by the National Family Health Survey (NFHS-5) and the CS rate varies significantly between states. The WHO has recommended using the Robson Ten-Group Classification System (TGCS) as a standard audit tool, which can be used to compare institutions and identify those high-contribution subgroups which can be targeted for quality improvement. In this study, CS rates were audited using the Robson TGCS, and factors that could be modified were identified at a tertiary care hospital.
Methods: This was a cross sectional observational study of all consecutive deliveries (2380 in 12 months) in a tertiary care hospital. Deliveries were grouped into the 10 Robson groups according to parity, gestational age, fetal presentation, onset of labour and the number of fetuses. Group-specific CS rates, absolute contributions to CS rates and relative contributions of each group to the CS rate were estimated. Multiple logistic regression analysis found independent factors associated with primary CS in Robson Group 1.
Results: Overall CS rate was 38.1% (n=907/2380). The biggest group was Robson Group 5 (previous CS, singleton cephalic, term) with 12.3% absolute contribution (92.1% of individuals within-group CS). Groups 1+2 together contributed 10.1%. Group 10 (preterm) contributed 4.0%. Risk factors for primary CS independent of the others were: non-progression of labour (aOR 4.8), fetal distress (aOR 3.6), nulliparous age ≥35 years (aOR 2.1) and BMI ≥30 (aOR 1.8). Elective repeat CS made up 58.3% of the total Group 5 CS.
Conclusions: Robson Groups 5 and 1 account for the majority of the above average CS rate at this institution. There is a need for targeted interventions, such as VBAC counselling, active labour management, and support for nulliparous women, to attain a clinically relevant CS rate
