Objective: To determine the groups using Robson classification within the obstetric population in our institute contributing substantially to the Caesarean section (CS) rate.Methods: All the women delivered in this hospital from January 2012 to January 2014 in were included in this study. The relative contribution of each group to the overall CS rate, relative size of group, and CS rate were calculated for the parturients according to Robson's Ten group classification.
Results:The caesarean section rate in our study was 33.1%. Group 5 contributed the most (11.9%) (Previous CS). Group 1 (Nulliparous, Spontaneous Labor) had the second highest contribution that of 6.37% and Group 2 (Nulliparous, Induction) and group 3 (Multiparous, Spontaneous Labor) had almost similar contribution of 3.6% and 3.46%, respectively. On further analysis of group 5, 43.6% women had caesarean section because of previous scar (including not willing for VBAC, scar tenderness, and more than 2 scars). In our study group 10 (Preterm) constitutes 9.1% of all deliveries.
Conclusion:Ten Group classification allows us to determine which target groups to investigate further to learn more about the underlying reasons for the differences in CS rates over time and potentially different places. In our study highest contribution of caesarean section came from group 5, which can be taken care of by avoiding primary caesarean sections.
