Robson Classification for cesarean section in a Public Hospital in Distrito Federal

Abstract

Abstract Objectives: to evaluate cesarean taxes by looking at Robson classification on 10 groups (G) and the principal indications at the prevalent groups and at G10. Methods: cross-sectional, observational, retrospective study, including all deliveries performed in a public hospital in Distrito Federal in 2019. Data were collected from medical records and pregnant women were classified in 10 groups. Pearson’s chi-squared test was used to calculate the p-value. The risk estimate for cesarean was defined by common odds ratio of Mantel-Haenszel, with calculation of odds ratio (OR) and 95% confidence interval (CI95%). Results: there were 2,205 deliveries, 1,084 (49.1%) of which were cesarean and 1,121 (50.9%) vaginal deliveries. The principal factors for cesarean were G5 (39.3%), G2 (21.2%) and G1 (13.6%). At G10, cesarean had 51.5% of births, not differing statistically from the other groups (p>0.05). Considering all preterm births, G6 to G10 and the other groups, there is a bigger chance of cesarean happening in relation to normal labor (OR=1.4; CI95%= 1.011-2.094; p=0.042). Dystocia remained at G1 and G2, previous cesarean at G5 and hypertensive syndrome at G10. Conclusion: cesarean was most prevalent delivery route, showing elevated rates even in primiparous and preterm births. Preponderance of dystocia and acute fetal distress suggests better evaluation of the diagnostic criteria, mainly in G1, G2 and G10.
