Study of Caesarean Section Births in a Tertiary Care Hospital in Mumbai Using Robson Classification System.

Introduction: Robson ten-group classification system is recommended by WHO (World health organization) as a global standard for assessment and monitoring caesarean section (CS) rates. This classification is simple and robust. It is prospective, easily reproducible and clinically relevant.

Methodology: We conducted a prospective observational study of CS births at a tertiary care institute. Caesarean births in a tertiary care hospital were classified using Robson classification system as recommended by WHO. The study was conducted for period of 6 months duration. The ethics committee of the institute approved this study. We enrolled 4771 consecutive women who delivered during this study period. We included patients who had vaginal delivery as well as those who had delivery by CS. Both live births and stillbirths (of at least 500-g birth weight or at least 22 weeks gestation (according to WHO recommendations) were included in this study.

Results: During this study period, we had 4771 deliveries, out of which 2231 pregnant women (46.76%) were delivered by CS as compared to 2540 vaginal deliveries. Women with previous CS (term with single cephalic pregnancy) were included in Robson group 5. Group 5 had the highest CS rate (13.41%). Robson group 5, 1 and 10 were the largest contributors to the high CS rates at our institute.

Conclusion: In our study, 4771 deliveries were conducted during this study period (6 months). Out of 4771 deliveries, CS was done in 2231 pregnant women (46.76%). 2540 women had vaginal deliveries. Group 5 (13.41%) which comprised of women with previous CS had the highest CS rate followed by group 1 and group 10. The second largest contribution was from Group 1 with CS rate of 9.01%. Robson Group 1 included nulliparous term women with single cephalic pregnancy in spontaneous labour. Group 10 was the third largest contributor to the overall CS. Group 10 included women who delivered preterm (single cephalic presentation). Group 10 contributed to 8.09% of overall CS rate. We should make every effort to provide CS for women requiring this procedure, rather than work towards achieving a specific rate for CS.
