Science Update: Known risk factors may account for only part of the U.S. increase in life-threatening childbirth complications
The increasing rate in the United States of severe maternal morbidity—life-threatening maternal childbirth complications—may not be accounted for by the simultaneous increase in known risk factors for these complications, suggests an analysis of California hospital records funded by the National Institutes of Health. To reduce the rate of severe maternal morbidity, more research is needed to identify additional risk factors and other potential causes for the increase, the authors concluded.
