To determine the factors leading to maternal critical care in a tertiary obstetric hospital and the associated trends. ⋯ The majority of maternal transfers for critical care occur postpartum, and in more than half of the cases the reason for transfer is hemorrhage or hypertensive disease. Women with a multiple pregnancy had a significantly greater rate of transfer than those with a singleton, and women with a triplet pregnancy had a greater rate than those with twins. There was a non-significant increase in the number of maternal transfers over the study period.
