First, do no harm: preventing elective inductions before 39 weeks
A recent article published in the
Journal of the American Board of Family Medicine reported that fewer than 1 in 5 board-certified family physicians provide routine prenatal care, and just over 13 percent perform deliveries. Therefore, more family physicians are referring patients for maternity care and have less influence over troubling national trends, such as declining rates of vaginal births after previous Cesarean delivery (VBAC) and increasing rates of "late" premature delivery (between 34 and 38 6/7ths weeks gestation) due for the most part to elective inductions.
In an editorial in the December 15th issue of
American Family Physician, Drs. Michael Cacciatore and D. Ashley Hill argue that the preponderance of evidence demonstrates that infants delivered before 39 weeks gestation without a medical indication have worse outcomes than those delivered closer to term:
The baseline neonatal intensive care unit (NICU) admission rate at 39 weeks was 2.6 percent, but this rate nearly doubled for each week before 38 weeks. Another group analyzed 13,258 elective cesarean deliveries, of which 35.8 percent were performed before 39 weeks, and found that infants born before 39 weeks had a significantly increased risk of adverse outcomes. Notably, this was also true for the neonates born at 38 weeks. A retrospective review of almost 180,000 births showed that the risk of severe respiratory distress syndrome was 22.5-fold higher for neonates born at 37 weeks and 7.5-fold higher for infants born at 38 weeks compared with those born at or after 39 weeks. The risk of an early term neonate being admitted to the NICU is approximately one in 20 deliveries, compared with about one in 50 for neonates born between 39 and 40 weeks.If elective inductions before 39 weeks gestation are apparently harmful, why are so many patients consenting to them? The authors point to a variety of reasons, including lack of knowledge, maternal discomfort, convenience, and patient and physician preference. To improve pregnancy outcomes, they recommend the universal adoption of several health system interventions shown to prevent early elective inductions. In addition, family physicians and other primary care clinicians who do not provide maternity care themselves can educate their patients and colleagues about the unnecessary harms that may result from this practice.
