Purpose: (1) To evaluate the association between immigration background and the occurrence of maternal near miss (MNM). (2) To identify medical co-factors, health-care utilization, and health-care disparities as explanations of a possibly higher risk of MNM among immigrants. Methods: We compared perinatal outcomes between immigrant women (first- or second-generation) versus non-immigrant women, delivering at three maternity hospitals in Berlin, Germany, 2011–2012. Near-miss events were defined as: HELLP syndrome, eclampsia, the occurrence or threat of uterine rupture, postpartum hemorrhage (PPH) > 1000 ml, sepsis, peripartal hysterectomy, cardiovascular complications, lung embolism. Logistic regression analyses were performed to determine the associations of immigration status, acculturation, and language competency with near-miss events, and of near-miss events with the perinatal outcomes. Results: The databank included 2647 first-generation immigrants, 889 second-generation immigrants, and 3231 women without an immigration background (total N = 6767). Near-miss events occurred in 141 women. The likelihood of near-miss events was lower among multiparous women (OR 0.6; 95% CI 0.42–0.87; p = 0.01). No other factors had a statistically significant influence. Near-miss events are associated with an elevated likelihood for an unfavorable perinatal condition: the ORs ranged from 2.15 for an arterial umbilical cord pH value < 7.1–2.47 for premature delivery. Conclusions: Immigration status does not change the risk of near-miss events. Besides parity, no medical or socio-demographic factors were identified that were associated with an elevated likelihood for the occurrence of severe peripartal complications. © 2019, Springer-Verlag GmbH Germany, part of Springer Nature.
