Background Intrahepatic cholestasis of pregnancy (ICP) is a complex liver disease with varying incidence worldwide. We compared ICP incidence and pregnancy outcomes with outcomes for normal pregnant controls. Methods We conducted a retrospective data analysis of perinatal registry data for the years 2011 and 2017 to compare the following outcome measures: stillbirths, labour induction, gestational diabetes, pre-eclampsia, antepartum haemorrhage, postpartum haemorrhage, preterm births, low Apgar score, acute neonatal respiratory morbidity, meconium aspiration and in-hospital neonatal death. Results The incidence of ICP was 8 per 1000 births from a total 31,493 singleton births with more cases in 2017 than in 2011. Women with ICP were almost six times more likely to have labour induced including significantly more moderate preterm births (defined as between 32 weeks and 36 weeks and 6 days of gestation)) seen more in 2011 than in 2017. Conclusion Women with ICP showed higher incidence of moderate preterm birth and induced labour but favourable maternal and neonatal outcomes.
