CARRENO, Bárbara et al. Tasa de cesáreas según la clasificacion de Robson: Análisis comparativo entre dos hospitales universitarios. Rev. chil. obstet. ginecol. [online]. 2018, vol.83, n.4, pp.415-425. ISSN 0048-766X.

Introduction and objectives:

The caesarean section execution for the interruption of pregnancy and its optimal rate of use, has been a controversial issue since its inception. In this line Robsons and Cols propose a classification to standardize and effectively compare the practices carried out in the different health institutions. The aim of this study was to compare the rate of cesareans performed during 2017 both at the “University Clinical Hospital of Chile” (HCUCH) and at the “San José de Osorno Hospital” (HBSJO), and in this way, describe their statistical differences.


The results were obtained by collecting data from the pavilion book available in both departments.


There was a significant difference in the cesarean rate between both hospitals. This difference reached 55.7% in the HCUCH, in contrast to 35.7% in the HBSJO. In the HCUCH, 87.8% of all the deliveries corresponded to women with low risk pregnancies, with cesarean sections performed in 52.9% of them. On the other hand, in the HBSJO the values were 74.6% and 32.2% respectively. The only categories in which there was no statistically significant difference in the rate of cesarean sections performed, were pregnancies with dystocia presentation and twin pregnancies, reaching a 100% of surgical intervention in this last group. The hypotheses that explain these differences lie mainly in the administrative organization and the population served in each hospital.


The different healthcare centers in our country are governed by different ways of functioning. This explains, among other things, the statistically significant difference that occurs when comparing the cesarean rate of the HCUCH and the HBSJO. We encourage in this study to use Robson's classification method to facilitate the supervision and critical comparison of these indices in hospitals.
