More and more American women (1 in 200) are opting for home birth, and midwife-assisted home birth is common in other developed countries. How safe is it compared to birth in a hospital? A new study sheds some light on the subject. It was recently published in the American Journal of Obstetrics and Gynecology: Maternal and newborn outcomes in planned home birth vs planned hospital births: a metaanalysis, by Wax et al.
All the existing studies have flaws. It would be ideal to do a study where women were randomly assigned to home or hospital birth; that isn’t possible, so we have to fall back on studies that are possible. Just comparing home births to hospital births isn’t good enough, because high-risk births occur primarily in hospitals, and between 9% and 37% of planned home births end up with transfer to the hospital during labor and are converted into hospital births. Cohort studies comparing planned home with planned hospital births provide the best sources of data by intended delivery location. There have been several such studies, but the numbers were small and the results were inconclusive.
