RE: Maternal and Newborn Outcomes in Planned Home Birth Vs. Planned Hospital Births: A Meta-Analysis, Wax JR, Lucas FL, Lamont M, et al., Am J Obstet Gynecol 2010

A new meta-analysis rushed to on-line publication well before its availability in print, concluded that less medical intervention, which is a characteristic feature of planned home birth, is associated with a tripling of the neonatal mortality rate compared with planned hospital births. In a study published online on July 1, 2010 in the American Journal of Obstetrics and Gynecology (AJOG), researchers at Maine Medical Center in Portland, Maine analyzed the results of multiple studies from around the world. The lead investigator, Joseph R. Wax, MD, Department of Obstetrics and Gynecology, Maine Medical Center, stated, "Our findings raise the question of a link between the increased neonatal mortality among planned home births and the decreased obstetric intervention in this group."

However, Canadian researchers whose data showing the safety of home birth in a well-organized and regulated system, were used in the meta-analysis, are sharply critical of the study. Dr. Michael C. Klein, a senior scientist at the Child and Family Research Institute in Vancouver and emeritus professor of family practice and pediatrics at the University of British Columbia said the U.S. conclusions did not consider the facts. "A meta-analysis is only as good as the articles entered into the meta-analysis-garbage in, garbage out. Moreover, within the article, Wax et al did their own sub-analysis of the studies in the meta-analysis, after removing out-of-date and low quality studies, and found no difference between home and hospital births for perinatal or neonatal mortality. Yet in the conclusion, they choose to report the results of the flawed total meta-analysis, which showed the increased neonatal mortality rate." Klein said that this is apparently a "politically motivated study in line with the policy of the American College of Obstetricians and Gynecolgists (ACOG) who is unalterably opposed to homebirth."

Saraswathi Vedam, a nurse midwife and researcher at the University of British Columbia who is considered to be an expert on assessing the quality of literature related to homebirth, states that the study is deeply flawed for several reasons, particularly, "the authors' conclusions are not supported by their own statistical analysis." Vedam states that Dr. Wax et al acknowledges the consistent findings of low perinatal and neonatal mortality in planned home births across the best quality studies they reviewed "but amazingly Wax does not emphasize or even mention this in his sole conclusion." This begs the question of whether the author's analysis and reporting of reviewed articles on homebirth do not support his foregone conclusion about the safety of homebirth.

The Midwives Alliance of North America, a professional organization of over 1200 members, believes childbearing women and those involved in maternal and child health policy should be made aware of the flaws and erroneous claims in the Wax et al study. There is a substantial body of evidence-based literature from well-designed studies that establishes the safety of planned homebirth with a skilled birth attendant. The fact that the American College of Obstetricians and Gynecologists maintains its position in opposition to homebirth, despite the evidence of its safety and efficacy, makes one question ACOG's motive in publishing Wax's substandard study.   

Midwives are the primary care providers in out of hospital settings. Whether their work is studied and scrutinized here in the US or abroad the findings are consistent. Trained midwives are qualified health professionals with the requisite expertise to provide mothers and newborns with outstanding care, using less intervention, resulting in maternal and infant outcomes as good as those in hospital settings under the care of obstetricians.

The American public, particularly women in the childbearing years and those who care for them, have a right to high quality research on childbirth. Research literature should not be used to cause undue alarm or limit a woman's choice regarding care providers, including skilled midwives, and place of birth.
