Motor vehicle accidents during pregnancy: a population-based study.

ABSTRACT

This population-based cohort study of more than 600,000 Australian women describes the incidence of motor vehicle accidents (MVA) during pregnancy and the immediate and subsequent pregnancy outcomes. In this study, 3.5 women per 1000 maternities were admitted to hospital following an MVA. Immediate delivery was uncommon 0.4% at <20 weeks of gestation and 3.5% at ≥ 20 weeks of gestation. Outcomes for those giving birth immediately were poor, with increased risk of antepartum haemorrhage, preterm birth, caesarean section and perinatal death. In contrast, women who remained undelivered following an MVA (96%) had similar pregnancy outcomes to women not involved in MVAs, and can be reassured.
