Grobman WA, et al. - Observational studies that compared elective induction of labor at 39 weeks among nulliparous women with expectant management were systematically reviewed. The association of elective induction with cesarean delivery, as well as other maternal and perinatal outcomes was determined performing meta-analysis. From 375 studies identified, inclusion criteria were met by 6 cohort studies which included 66,019 women undergoing elective labor induction at 39 weeks and 584,390 undergoing expectant management. Outcomes suggest a significantly lower risk of cesarean delivery, maternal peripartum infection, and perinatal adverse outcomes, including respiratory morbidity, intensive care unit admission, and mortality in correlation with elective induction of labor at 39 weeks, compared with expectant management beyond that gestational age.
