Robson's Ten Group Classification System to Evaluate Cesarean Section Rates in Honduras: The Relevance of Labor Induction.

Objective:  To use the Robson Ten Group Classification (RTGC) to analyze cesarean section (CS) rates in a Honduran maternity hospital, with focus in groups that consider induction of labor.

Methods:  Cross-sectional study. Women admitted for childbirth (August 2017 to October 2018) were classified according to the RTGC. The CS rate for each group and the contribution to the overall CS rate was calculated, with further analyses of the induction of labor among term primiparous (group 2a), term multiparous (group 4a), and cases with one previous CS (group 5.1).

Results:  A total of 4,356 women were considered, with an overall CS rate of 26.1%. Group 3 was the largest group, with 38.6% (1,682/4,356) of the cases, followed by Group 1, with 30.8% (1,342/4,356), and Group 5, with 10.3% (450/4,356). Considering the contribution to overall CS rates per group, Group 5 contributed with 30.4% (345/1,136) of the CSs and within this group, 286/345 (82.9%) had 1 previous CS, with a CS rate > 70%. Groups 1 and 3, with 26.6% (291/1,136) and 13.5% (153/1,136), respectively, were the second and third larger contributors to the CS rate. Groups 2a and 4a had high induction success, with low CS rates (18.4 and 16.9%, respectively).

Conclusion:  The RTGC is a useful tool to assess CS rates in different healthcare facilities. Groups 5, 1, and 3 were the main contributors to the CS rate, and groups 2 and 4 showed the impact and importance of induction of labor. These findings may support future interventions to reduce unnecessary CS, especially among primiparous and in women with previous CS.
