AIM: To identify the factors, risks, and mortality associated with unplanned out-of-hospital births. MATERIAL AND METHODS: This observational, retrospective, case-control study was conducted between 2005 and 2013 through a review of medical records from the hospital network of a county of Brazil. Mother-child dyads were divided into in-hospital births and unplanned out-of-hospital births. For hypothesis testing involving quantitative variables, parametric and nonparametric methods (t-test or Mann-Whitney test, respectively) were used as appropriate after ascertaining normality of distribution via the Kolmogorov-Smirnov or Shapiro-Wilk tests. The chi-square test, Fisher's exact test, odds ratios, and 95% confidence intervals were used to assess the relationship between categorical variables. A binary logistic regression was applied for pooled analysis of those variables that, when analyzed in isolation, had significant p-values on hypothesis testing. In all tests, p-values <0.05 were considered statistically significant. RESULTS: Of the 420 records, 117 corresponded to out-of-hospital births dyads. Mothers were predominantly nonwhite (p<0.001), with a history of inadequate antenatal care (p<0.001), multiparous (p<0.001), aged >25 years (p=0.031), and had more puerperal complications (p<0.001). Their newborns had low birth weight (Odds Ratios: 2.22; 95% CI: [1.4-3.4]; p<0.001), higher morbidity (p=0.009), a higher rate of admission to neonatal intensive care and stepdown units (p=0.030), and prolonged length of stay (p<0.001). CONCLUSION: The risk of maternal and neonatal complications, as well as the neonatal mortality rate, were higher for unplanned out-of-hospital deliveries. It occurred predominantly in nonwhite, older, multiparous women who had received incomplete antenatal care and who lived far from perinatal care centers.
