To analyze and compare the frequency of cesarean sections and vaginal deliveries through the Robson Classification in pregnant women attended at a tertiary hospital in two different periods.
Cross-sectional, retrospective study of birth records, comprising 4,010 women, conducted from January 2014 to December 2015 in the only public regional referral hospital for the care of high- risk pregnancies, located in Southern Brazil.
The overall cesarean section rate reached 57.5% and the main indication was the existence of a previous uterine cesarean scar. Based on the Robson Classification, groups 5 (26.3%) and 10 (17.4%) were the most frequent ones. In 2015, there was a significant increase in the frequency of groups 1 and 3 ( < 0.001), when compared with the previous year, resulting in an increase in the number of vaginal deliveries ( < 0.0001) and a reduction in cesarean section rates.
The Robson Classification proved to be a useful tool to identify the profile of parturients and the groups with the highest risk of cesarean sections in different periods in the same service. Thus, it allows monitoring in a dynamic way the indications and delivery routes and developing actions to reduce cesarean rates according to the characteristics of the pregnant women attended.
通过罗布斯分类法分析并比较在两家不同医院就诊的孕妇的剖宫产率和阴道分娩率。
这是一项回顾性的横断面研究，纳入了 2014 年 1 月至 2015 年 12 月期间在巴西南部唯一一家为高危妊娠提供服务的公立地区转诊医院的 4010 名产妇的分娩记录。
总的剖宫产率为 57.5%，主要指征是存在既往子宫剖宫产瘢痕。根据 Robson 分类，第 5 组（26.3%）和第 10 组（17.4%）最为常见。2015 年，与前一年相比，第 1 组和第 3 组（ < 0.001）的频率显著增加，导致阴道分娩数量增加（ < 0.0001），剖宫产率降低。
Robson 分类法被证明是一种有用的工具，可以识别不同时期同一服务中产妇的特征和剖宫产风险最高的人群。因此，它可以动态监测指征和分娩方式，并根据孕妇的特点采取行动来降低剖宫产率。
