Abstract
We conducted a hospital based descriptive study based on data routinely collected in a perinatal information system.4 We analysed data from 122 hospitals in 16 Latin American countries that had reported 416 852 deliveries between 1995 and 1998. We selected hospitals reporting more than 35 spontaneous vaginal deliveries in primiparous women, which is the sample size required to give a 95% confidence interval of 10% either way for an episiotomy rate of 90%. This selection comprised 105 hospitals in 14 countries, which reported 94 472 spontaneous vaginal deliveries in primiparous women. We report episiotomy rates by hospital, with medians (interquartile ranges) as a summary measure.
