Epidemiologic Reports, SurveysUsing Interinstitutional Practice Variation to Understand the Risks and Benefits of Routine Labor Induction at 41+0 WeeksHutcheon, J.A.; Harper, S.; Strumpf, E.C.; Lee, L.; Marquette, G.Author Information Perinatal Services British Columbia, Provincial Health Services Authority, Vancouver, BC, Canada Obstetric Anesthesia Digest: June 2016 - Volume 36 - Issue 2 - p 71 doi: 10.1097/01.aoa.0000482603.34124.ec Buy Metrics Abstract (BJOG. 2015;122(7):973–981) There is no consensus regarding the best clinical management practices for women who remain pregnant a week or more past their expected delivery date, due in part to the lack of high-quality evidence on the risks and benefits of routine labor induction at 41 weeks. The present study aimed to determine whether routine labor induction at 41+0 weeks’ gestation increases the risk of cesarean delivery (CD), instrumental delivery, or maternal or neonatal health complications compared with expectant management. The study cohort was women in British Columbia (BC), Canada who remained pregnant past 41+0 weeks and delivered at one of the province’s 42 hospitals between 2008 and 2012.
