A Letter to "Time" on Home Birth

October 5, 2010

Last month, Time magazine published an article, American Women: Birthing Babies at Home, which covered the small but increasing number of women choosing home birth, the legal status for providers, safety issues, and the debate over home birth in general. It included commentary on the Wax meta-analysis, summarizing the controversy thusly:

The authors of the paper, which consists of a review of 12 previous studies, acknowledged significant benefits associated with home birth: fewer maternal interventions, including epidurals, episiotomies and C-sections; and fewer cases of premature birth and low birth weight.

But the finding that made headlines was that planned home births led to a two-to-three-times higher risk of neonatal death than planned hospital deliveries among healthy, low-risk women.

Time reporter Catherine Elton notes that the study’s lead author Dr. Joseph Wax “cautions against alarm,” quoting him as stating: “Home birth is quite safe for the baby. But not as safe as a hospital birth.”

Below is an unpublished letter to the editor of Time coordinated by OBOS’s Judy Norsigian:

Catherine Elton’s recent article is a thoughtful analysis of the the fragmented and sometimes underground system of home birth care in the United States, and the reasons women access it in spite of these shortcomings. However, in her discussion of the recent high-profile meta-analysis showing a significantly higher neonatal death rate in home birth compared with hospital birth, Elton states that the meta-analysis included hundreds of thousands of births, but fails to make it clear that the researchers’ calculation of neonatal mortality risk was not based on hundreds of thousands of births…not by a long shot. For reasons that are unclear, the researchers excluded from their neonatal mortality analysis a study that included over a half-million births, leaving fewer than 10,000 planned home births in their calculations of newborn death rates. The large Dutch study that was excluded found identical, very low rates of newborn deaths in the first week of life in both the planned home birth and planned hospital birth groups, and these data come from much more reliable databases than the Washington study, which the meta-analysis researchers included and which Elton acknowledged was flawed. All reliable data on home birth midwifery in regulated and integrated systems like the Netherlands and Canada suggest that home birth is safe for the baby and associated with significant health benefits for the mother.
