(Please see my comments following this blog)
I found the self-reflection and critiquing of their own research to be honest and refreshing in stark contrast to the first article’s air of certainty which feels like smugness to me (my bias!). Cheng, et al admit their study has limitations. “As a retrospective study, it may have included confounding or missing data that could potentially bias our findings.” They go on to say, “….administrative data, such as birth certificate data, may contain inaccurate information.” Now isn’t that refreshing to hear from a researcher? They also honestly admit they could not identify or differentiate women who planned a home birth but who were transferred to hospitals which they admit occurs in 10-15% of planned home births (Notice the use of 10-15% rather than the skewed numbers of up to 47% Dr. Chervenak used in a previous opinion piece last year). This could elevate the risks at home but they admit they cannot be sure. Finally, Dr. Cheng concludes, “Because of the complex tradeoff between maternal benefits and neonatal risk, women who contemplate location of birth should be fully informed about both sites”.
