RESUMEN

BACKGROUND: More than 1 million women have their labor induced in the United States each year, and synthetic oxytocin infusion is the most common method used. However, compared to spontaneous labor, medical induction is resource intensive, has increased obstetric risks, and is associated with less successful breastfeeding. In contrast to the endogenous oxytocin hormone, which is released in a pulsatile fashion in the brain, synthetic oxytocin is continuously infused intravenously, resulting in important limitations related to efficacy, safety, and cost. Akin to spontaneous labor contractions, infant suckling of the breast nipple is known to stimulate the pulsatile release of endogenous oxytocin from the posterior pituitary gland. Nipple stimulation therapy via an electric breast pump similarly stimulates endogenous oxytocin release and may be a favorable inpatient method for patients undergoing labor induction. OBJECTIVE: This study aims to examine whether inpatient nipple stimulation therapy is an efficacious labor induction method that increases the likelihood of spontaneous vaginal delivery and sustained breastfeeding and determine whether it is a cost-effective approach. METHODS: This is a multicenter, pragmatic, open-label, parallel-group randomized controlled trial of nulliparous patients with singleton gestations ≥36 weeks undergoing labor induction. This trial compares inpatient nipple stimulation therapy via an electric breast pump versus immediate synthetic oxytocin infusion without nipple stimulation. This trial including 988 nulliparas will provide adequate statistical power to detect clinically meaningful differences in delivery mode and breast milk as the sole source of nutrition for newborns at hospital discharge or 72 hours after birth. RESULTS: The project received pilot funding in 2021 and full funding in 2023. Enrollment for this study began in November 2021 at a single site, and as of May 2024, recruitment is underway at 3 study sites. It is anticipated that enrollment will be completed by late 2026. CONCLUSIONS: Successful completion of this trial will provide rigorous data to determine whether inpatient nipple stimulation therapy with an electric breast pump can improve the way we induce labor and positively impact breastfeeding success and early infant nutrition through lactation.

RESUMEN

OBJECTIVE: To determine whether a community-informed, language-concordant postpartum video education campaign, developed with community input, improves patients' knowledge of warning signs for postpartum maternal mortality (infection, hemorrhage, hypertensive disorders, and postpartum depression) compared with routine discharge procedures. METHODS: A single-center, investigator-blinded, parallel-group randomized controlled trial of postpartum individuals who delivered at a large, urban, tertiary care hospital. Eligible participants were enrolled and completed a baseline knowledge questionnaire. After delivery, they were randomized to routine discharge education (control) or routine education plus video education (intervention). After discharge education, patient knowledge was again assessed in both groups before participants left the hospital. The primary outcome was the percentage of participants who showed improvement in their knowledge, measured by the number of correct questionnaire responses after education compared with their baseline, assessed as a binary outcome. A sample size of 150 (75 per group) was planned to detect a 25% absolute increase in the frequency of the primary outcome. RESULTS: From July to August 2022, 296 participants were screened and 200 were randomized (100 per group). Eighty-two percent of participants had college or graduate education, and 71.5% had commercial insurance. There was no significant difference in baseline characteristics. There was no statistically significant difference in the percentage of participants who improved their scores between the baseline and posteducation questionnaires (64.5% vs 50.0%, P =.09). However, the median posteducation questionnaire total score was significantly higher in the video education group (14 [interquartile range 12-15] vs 13 [interquartile range 12-14], P =.003). In addition, they more frequently reported that video education was "very helpful" (83.9% vs 72.5%, P =.23) and that they were "very satisfied" with their education (86.1% vs 75.5%, P =.29). CONCLUSION: Enhanced postpartum education through a novel video did not result in a statistically significant difference in frequency of improved score on the posteducation questionnaires but was associated with increased satisfaction with care.
