title: Mode of delivery among women admitted with polyhydramnios.
abstract: A retrospective matched case control study was conducted to examine the incidence of caesarean delivery (CD) among women admitted with polyhydramnios with and without a trial of labour compared to women with normal amniotic fluid index (AFI). Singleton pregnancies diagnosed with polyhydramnios upon admission to labour between 2003 and 2013 were included. A control group (normal AFI) matched at a ratio of 1:1 was randomly selected. Primary outcome was the incidence of CD. A total of 588 women were included. The overall incidence of CD was significantly higher among women with polyhydramnios (31.3%) compared to the controls (18.7%), (p < .001). The incidences of both non-labouring caesarean and intrapartum operative deliveries were significantly higher among women with polyhydramnios compared to the controls (p = .007 and p = .01, respectively). On a multiple logistic regression model, polyhydramnios was found to be an independent risk factor for delivery by a caesarean (p = .0015; OR 2.0; 95%CI 1.30-2.90).
