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

Abstract

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. Objetivo Utilizar a Classificação de Dez Grupos de Robson (RTGC, na sigla em inglês) para analisar as taxas de cesárea (CS, na sigla em inglês) em uma maternidade hondurenha. Métodos Estudo de corte transversal em uma maternidade em Honduras. As mulheres internadas para o parto (agosto de 2017 a outubro de 2018) foram classificadas segundo a RTGC. Calculou-se a taxa de CS para cada grupo e a contribuição para a taxa geral de CS, com análises adicionais da indução do trabalho de parto entre as primíparas a termo (grupo 2a), multíparas a termo (grupo 4a) e casos com uma CS anterior (grupo 5.1). Resultados foram consideradas 4.356 mulheres, com uma taxa geral de CS de 26.1%. O Grupo 3 foi o maior grupo, com 38,.6% (1.682/4.356) dos casos; seguido pelo Grupo 1, com 30,8% (1.342/4.356), e pelo Grupo 5, com 10,3% (450/4,356). Considerando a contribuição para as taxas globais de CS por grupo, o Grupo 5 contribuiu com 30,4% (345/1,136) das CS, dos quais 286 (82.9%) tinha uma CS anterior, com um índice de CS > 70%. Os grupos 1 e 3, com 291/1.136 (26.6%) e 153/1.136 (13,5%), respectivamente, foram o segundo e terceiro maiores contribuintes para a taxa de CS. Os grupos 2a e 4a tiveram alto sucesso de indução, com baixas taxas de CS (18.4 e 16.9%, respectivamente). Conclusão O RTGC é uma ferramenta útil para avaliar as taxas de CS em diferentes unidades de saúde. Os grupos 5, 1 e 3 foram os principais contribuintes para a taxa de CS. Estes achados podem apoiar intervenções futuras para reduzir as CS desnecessárias, especialmente entre primíparas e em mulheres com uma CS anterior. Costa M. L., Paz L. D. C, and Banegas R.
