“Of the 5418 women, 655 (12.1%) were transferred to hospital intrapartum or postpartum…
Five out of every six women transferred were transferred before delivery, half (51.2%) for failure to progress, pain relief or exhaustion.
After delivery, 1.3% of mothers and 0.7% of newborns were transferred to hospital, most commonly for maternal haemorrhage (0.6% of total births), retained placenta (0.5%), or respiratory problems in the newborn (0.6%).
The midwife considered the transfer urgent in 3.4% of intended home births.
Transfers were four times as common among primiparous women (25.1%) as among multiparous women (6.3%) but urgent transfers were only twice as common among primiparous women (5.1%) as among multiparous women (2.6%).”
