ObjectiveIdentify factors associated with the need for pharmacologic therapy (PT) among opioid exposed newborn (OENs).Study designRetrospective analysis of a statewide database of OENs from 2017 through 2019. Multivariable mixed-effects logistic regression modeled the association of maternal characteristics, infant characteristics, and family engagement practices on the receipt of PT.ResultsOf 2098 OENs, 44.8% required PT for NOWS. Higher odds of PT were associated with in-utero exposure to medication treatment for opioid use disorder (MOUD) and non-prescribed opioids in addition to MOUD; nicotine, benzodiazepines, SSRIs; male; out-born infants and mother’s ineligibility to provide breast-milk. Lower odds were associated with increasing birth year, skin-to-skin (STS) care, and rooming-in.ConclusionMale, out-born infants exposed to MOUD with additional non-prescribed opioids, nicotine, benzodiazepines and SSSRIs with mothers ineligible to provide breast-milk were more likely to require PT, while modifiable care practices including STS care, and rooming-in decreased the likelihood of PT.

Background
The rate of induction of labor in the U.S. has risen from 9.6% in 1990 to 25.7% in 2018, including 31.7% of first-time births. Recent studies that have examined inductions have been small qualitative studies or relied on either medical records or administrative data. This study examines induction from the perspective of those women who experienced it, with a particular focus on the prevalence and predictors of inductions for nonmedical indications, women’s experience of pressure to induce labor and the relationship between the attempt to medically initiate labor and cesarean section.
Methods
Study data are drawn from the 2119 respondents to the
Listening to Mothers in California
survey who were planning to have a vaginal birth in 2016. Mothers were asked if there had been an attempt to medically initiate labor, if it actually started labor, if they felt pressured to have the induction, if they had a cesarean and the reason for the induction. Reasons for induction were classified as either medically indicated or elective.
Results
Almost half (47%) of our respondents indicated an attempt was made to medically induce their labor, and 71% of those attempts initiated labor. More than a third of the attempts (37%) were elective. Attempted induction overall was most strongly associated with giving birth at 41+ weeks (aOR 3.28; 95% C.I. 2.21–4.87). Elective inductions were more likely among multiparous mothers and in pregnancies at 39 or 40 weeks. The perception of being pressured to have labor induced was related to higher levels of education, maternal preference for less medical intervention in birth, having an obstetrician compared to a midwife and gestational ages of 41+ weeks. Cesarean birth was more likely in the case of overall induction (aOR 1.51; 95% C.I. 1.11–2.07) and especially following a failed attempt at labor induction (aOR 4.50; 95% C.I. 2.93–6.90).
Conclusion
Clinicians counselling mothers concerning the need for labor induction should be aware of mothers’ perceptions about birth and engage in true shared decision making in order to avoid the maternal perception of being pressured into labor induction.

Low vitamin D status in pregnancy was proposed as a risk factor of preeclampsia.
We assessed the effect of vitamin D supplementation (4,400 vs. 400 IU/day), initiated early in pregnancy (10-18 weeks), on the development of preeclampsia. The effects of serum vitamin D (25-hydroxyvitamin D [25OHD]) levels on preeclampsia incidence at trial entry and in the third trimester (32-38 weeks) were studied. We also conducted a nested case-control study of 157 women to investigate peripheral blood vitamin D-associated gene expression profiles at 10 to 18 weeks in 47 participants who developed preeclampsia.
Of 881 women randomized, outcome data were available for 816, with 67 (8.2%) developing preeclampsia. There was no significant difference between treatment (N = 408) or control (N = 408) groups in the incidence of preeclampsia (8.08% vs. 8.33%, respectively; relative risk: 0.97; 95% CI, 0.61-1.53). However, in a cohort analysis and after adjustment for confounders, a significant effect of sufficient vitamin D status (25OHD ≥30 ng/ml) was observed in both early and late pregnancy compared with insufficient levels (25OHD <30 ng/ml) (adjusted odds ratio, 0.28; 95% CI, 0.10-0.96). Differential expression of 348 vitamin D-associated genes (158 upregulated) was found in peripheral blood of women who developed preeclampsia (FDR <0.05 in the Vitamin D Antenatal Asthma Reduction Trial [VDAART]; P < 0.05 in a replication cohort). Functional enrichment and network analyses of this vitamin D-associated gene set suggests several highly functional modules related to systematic inflammatory and immune responses, including some nodes with a high degree of connectivity.
Vitamin D supplementation initiated in weeks 10-18 of pregnancy did not reduce preeclampsia incidence in the intention-to-treat paradigm. However, vitamin D levels of 30 ng/ml or higher at trial entry and in late pregnancy were associated with a lower risk of preeclampsia. Differentially expressed vitamin D-associated transcriptomes implicated the emergence of an early pregnancy, distinctive immune response in women who went on to develop preeclampsia.

Lost opportunities to prevent early onset type 2 diabetes mellitus after a pregnancy complicated by gestational diabetes
2016
ObjectivesGestational diabetes mellitus (GDM) greatly increases the risk of developing diabetes in the decade after delivery, but few women receive appropriately timed postpartum glucose testing (PPGT) or a referral to primary care (PC) for continued monitoring. This qualitative study was designed to identify barriers and facilitators to testing and referral from patient and providers' perspectives.MethodsWe interviewed patients and clinicians in depth about knowledge, values, priorities, challenges, and recommendations for increasing PPGT rates and PC linkage. Interviews were coded with NVIVO data analysis software, and analyzed using an implementation science framework.ResultsWomen reported motivation to address GDM for the health of the fetus. Most women did not anticipate future diabetes for themselves, and focused on delivery outcomes rather than future health risks. Patients sought and received reassurance from clinicians, and were unlikely to discuss early onset following GDM or preventive measures. PPGT barriers described by patients included provider not mentioning the test or setting it up, transportation difficulties, work responsibilities, fatigue, concerns about fasting while breastfeeding, and timing of the test after discharge from obstetrics, and no referral to PC for follow-up. Practitioners described limited communication among multiple care providers during pregnancy and delivery, systems issues, and separation of obstetrics from PC.ConclusionsPatients' barriers to PPGT included low motivation for self-care, structural obstacles, and competing priorities. Providers reported the need to balance risk with reassurance, and identified systems failures related to test timing, limitations of electronic medical record systems (EMR), lack of referrals to PC, and inadequate communication between specialties. Prevention of early onset has great potential for medical cost savings and improvements in quality of life.

The primary objective of this study was to implement a same-day discharge pathway for patients undergoing minimally invasive gynecologic surgery at an urban, safety-net hospital. Prior to implementation, patients routinely spent one to two nights in the hospital postoperatively. This project was implemented on December 3, 2018. We utilized a screening tool to identify eligible patients for same-day discharge. The primary outcome measure was the percentage of patients discharged the same day of the surgery. We compared data between patients discharged home same day versus patients admitted to the hospital, as well as patients who underwent benign minimally invasive gynecologic surgery prior to and after project implementation. Of the 237 patients undergoing minimally invasive gynecologic surgery, 209 were eligible for same-day discharge. More than half (111, 53.1%) of the eligible patients were discharged home on the same day. Same-day discharge was not found to be associated with an increased risk of adverse events compared to patients who were not discharged same day. Same-day discharge after minimally invasive gynecologic surgery is safe and feasible in an urban safety-net hospital, especially with the addition of a screening tool to identify social determinants of health prior to surgery.

Background/Objectives: Previous literature has described that non-white pregnant patients are at increased risk of severe morbidity from obstetric hemorrhage (OBH). Here, we investigate whether such disparities are secondary to delay in the administration of postpartum oxytocin for non-white patients compared to white patients. Methods: This is a retrospective cohort study of all deliveries from 2018 to 2019, comparing (1) Hispanic white or non-white race (HW/NWR) pregnant people and (2) non-Hispanic white (NHW) pregnant people. Our primary outcome was the time from delivery to the first dose of postpartum oxytocin, and our secondary outcome was the frequency of other hemorrhage interventions. Results: Out of 3832 patients with self-identified race and ethnicity recorded in their patient record, 644 patients identified as NHW, and 3188 patients identified as HW/NWR. We found no difference in time to first dose of postpartum oxytocin (p = 0.51), and there was also no difference in the frequency of other hemorrhage-related interventions. Conclusions: Our study found no delay in the administration of postpartum oxytocin for non-white patients.

Labor and Delivery Experiences of Mothers with Suspected Large Babies
2015
Objective
To characterize the prevalence of and factors associated with clinicians’ prenatal suspicion of a large baby; and to determine whether communicating fetal size concerns to patients was associated with labor and delivery interventions and outcomes.
Methods
We examined data from women without a prior cesarean who responded to
Listening to Mothers III
, a nationally representative survey of women who had given birth between July 2011 and June 2012 (n = 1960). We estimated the effect of having a suspected large baby (SLB) on the odds of six labor and delivery outcomes.
Results
Nearly one-third (31.2 %) of women were told by their maternity care providers that their babies might be getting “quite large”; however, only 9.9 % delivered a baby weighing ≥4000 g (19.7 % among mothers with SLBs, 5.5 % without). Women with SLBs had increased adjusted odds of medically-induced labor (AOR 1.9; 95 % CI 1.4–2.6), attempted self-induced labor (AOR 1.9; 95 % CI 1.4–2.7), and use of epidural analgesics (AOR 2.0; 95 % CI 1.4–2.9). No differences were noted for overall cesarean rates, although women with SLBs were more likely to ask for (AOR 4.6; 95 % CI 2.8–7.6) and have planned (AOR 1.8; 95 % CI 1.0–4.5) cesarean deliveries. These associations were not affected by adjustment for gestational age and birthweight.
Conclusions for Practice
Only one in five US women who were told that their babies might be getting quite large actually delivered infants weighing ≥4000 g. However, the suspicion of a large baby was associated with an increase in perinatal interventions, regardless of actual fetal size.

BackgroundMost women who have had previous caesareans are eligible to have labour after caesarean (LAC), but only 11.9% do so. Studies show the majority of women have already decided about future mode of birth (FMOB) before a subsequent pregnancy. Hence, providing women with LAC counselling soon after birth may help women plan for future pregnancies. Prior to our intervention, our hospital had no method of ensuring that women received LAC counselling after caesarean section. The purpose of this QI initiative was to assess whether formal LAC documentation on labour and delivery (L&D) improves rates of LAC counselling post partum.MethodsOur three-part intervention included: (1) surgeon’s assessment of LAC feasibility in the operative note, (2) written LAC education for women in discharge paperwork and (3) documentation of LAC counselling in the discharge summary. We implemented these changes on L&D in January 2019. We conducted phone surveys of 40 women after caesarean preintervention and postintervention. Surveys included questions regarding three primary outcomes: whether or not they had received LAC counselling either in the hospital or at a postpartum visit, and whether or not they would pursue LAC as FMOB. Surveys also assessed two secondary outcomes: (1) women’s understanding of the indications for surgery and (2) their involvement in the decision process. We used a χ2 analysis to assess primary outcomes and a Fisher’s exact test to assess secondary outcomes. We also surveyed providers about the culture of LAC counselling at our hospital.ResultsAfter our intervention, there was a significant difference between the number of women reporting LAC postpartum counselling (30.77% vs 53.8%, p=0.04). There was also a significant difference in the number of women feeling involved in the decision-making process (68% vs 95%, p=0.03). Providers reported improved knowledge/confidence around LAC counselling (58%–100%). Providers universally stated that LAC counselling has become more ingrained in the culture on L&D.ConclusionsDocumentation of LAC counselling improved the consistency with which providers incorporated LAC counselling into postpartum care. Addressing FMOB at the time of pLTCS and documenting that counselling may be an effective first step in empowering women to pursue LAC in future pregnancies.
