Association of Cannabis Use With Nausea and Vomiting of Pregnancy

Our objective was to evaluate whether cannabis use was associated with nausea and vomiting in early pregnancy. Participants from nuMoM2b (Nulliparous Pregnancy Outcomes Study: Monitoring Mothers-to-Be) enrolled from October 2010 through September 2013 with a PUQE (Pregnancy-Unique Quantification of Emesis) questionnaire and an available stored urine sample from the first study visit (median gestational age 12 weeks) were included. Cannabis exposure was ascertained by urine immunoassay for 11-nor-9-carboxy-delta-9-tetrahydrocannabinol (THC-COOH); positive results were confirmed with liquid chromatography tandem mass spectrometry. The primary outcome was moderate-to-severe nausea by the PUQE score. Overall, 9,250 participants were included, and 5.8% (95% CI 5.4-6.3%) had detectable urine THC-COOH. In adjusted analyses, higher THC-COOH levels were associated with greater odds of moderate-to-severe nausea (20.7% in the group with THC-COOH detected vs 15.5% in the group with THC-COOH not detected, adjusted odds ratio 1.6, 95% CI 1.1-2.2 for a 500 ng/mg Cr THC-COOH increment).

Umbilical Cord Collection and Drug Testing to Estimate Prenatal Substance Exposure in Utah

OBJECTIVE

Our primary objective was to estimate statewide prenatal substance exposure based on umbilical cord sampling. Our secondary objectives were to compare prevalence of prenatal substance exposure across urban, rural, and frontier regions, and to compare contemporary findings to those previously reported.

METHODS

We performed a cross-sectional prevalence study of prenatal substance exposure, as determined by umbilical cord positivity for 49 drugs and drug metabolites, through the use of qualitative liquid chromatography-tandem mass spectrometry. All labor and delivery units in Utah (N=45) were invited to participate. Based on a 2010 study using similar methodology, we calculated that a sample size of at least 1,600 cords would have 90% power to detect 33% higher rate of umbilical cords testing positive for any substance. Deidentified umbilical cords were collected from consecutive deliveries at participating hospitals. Prevalence of prenatal substance exposure was estimated statewide and by rurality using weighted analysis.

RESULTS

From November 2020 to November 2021, 1,748 cords (urban n=988, rural n=384, frontier n=376) were collected from 37 hospitals, representing 92% of hospitals that conduct 91% of births in the state. More than 99% of cords (n=1,739) yielded results. Statewide, 9.9% (95% CI 8.1-11.7%) were positive for at least one substance, most commonly opioids (7.0%, 95% CI 5.5-8.5%), followed by cannabinoid (11-nor-9-carboxy-delta-9-tetrahydrocannabinol [THC-COOH]) (2.5%, 95% CI 1.6-3.4%), amphetamines (0.9%, 95% CI 0.4-1.5), benzodiazepines (0.5%, 95% CI 0.1-0.9%), alcohol (0.4%, 95% CI 0.1-0.7%), and cocaine (0.1%, 95% CI 0-0.3%). Cord positivity was similar by rurality (urban=10.3%, 95% CI 8.3-12.3%, rural=7.1%, 95% CI 3.5-10.7%, frontier=9.2%, 95% CI 6.2-12.2%, P=.31) and did not differ by substance type. Compared with a previous study, prenatal exposure to any substance (6.8 vs 9.9%, P=.01), opioids (4.7 vs 7.0% vs 4.7%, P=.03), amphetamines (0.1 vs 0.9%, P=.01) and THC-COOH (0.5 vs 2.5%, P<.001) increased.

CONCLUSION

Prenatal substance exposure was detected in nearly 1 in 10 births statewide.

Maternal Marijuana Exposure, Feto-Placental Weight Ratio, and Placental Histology

OBJECTIVE

Marijuana use is associated with placenta-mediated adverse pregnancy outcomes including fetal growth restriction, but the mechanism remains uncertain. The objective was to evaluate the association between maternal marijuana use and the feto-placental weight ratio (FPR). Secondarily, we aimed to compare placental histology of women who used marijuana to those who did not.

STUDY DESIGN

This was a secondary analysis of singleton pregnancies enrolled in a multicenter and case-control stillbirth study. Prior marijuana use was detected by electronic medical record abstraction or cord homogenate positive for 11-nor-delta-9-tetrahydrocannabinol-9-carboxylic acid. Prior tobacco use was detected by self-report or presence of maternal serum cotinine. Stillbirths and live births were considered separately. The primary outcome was FPR. Association of marijuana use with FPR was estimated with multivariable linear modeling adjusted for fetal sex, preterm birth, and tobacco use. Comparisons between groups for placental histology were made using Chi-square and stratified by live birth and stillbirth, term and preterm deliveries, and fetal sex.

RESULTS

Of 1,027 participants, 224 were stillbirths and 803 were live births. Overall, 41 (4%) women used marijuana during the pregnancy. The FPR ratio was lower among exposed offspring but reached statistical significance only for term stillbirths (mean 6.84 with marijuana use vs. mean 7.8 without use, p < 0.001). In multivariable modeling, marijuana use was not significantly associated with FPR (p = 0.09). There were no differences in histologic placental features among those with and without marijuana use overall or in stratified analyses.

CONCLUSION

Exposure to marijuana may not be associated with FPR. Similarly, there were no placental histologic features associated with marijuana exposure. Further study of the influence of maternal marijuana use on placental development and function is warranted to better understand the association between prenatal marijuana use and poor fetal growth.

KEY POINTS

· Maternal marijuana exposure was not associated with the feto-placental weight ratio.. · Marijuana exposure was not associated with differences in placental histology.. · Concerning trend toward lower feto-placental weight ratios among marijuana-exposed stillbirths..

Directly Measured Costs of Severe Maternal Morbidity Events during Delivery Admission Compared with Uncomplicated Deliveries

OBJECTIVE

To estimate the actual excess costs of care for delivery admissions complicated by severe maternal morbidity (SMM) compared with uncomplicated deliveries.

STUDY DESIGN

This is a retrospective cohort study of all deliveries between October 2015 and September 2018 at a single tertiary academic center. Pregnant individuals ≥ 20 weeks' gestation who delivered during a hospital admission (i.e., a "delivery admission") were included. The primary exposure was SMM, as defined by Centers for Disease Control and Prevention (CDC) criteria, CDC criteria excluding blood transfusion, or by validated hospital-defined criteria (intensive care unit admission or ≥ 4 units of blood products). Potential SMM events identified via administrative and blood bank data were reviewed to confirm SMM events had occurred. Primary outcome was total actual costs of delivery admission derived from time-based accounting and acquisition costs in the institutional Value Driven Outcomes database. Cost of delivery admissions with SMM events was compared with the cost of uncomplicated delivery using adjusted generalized linear models, with separate models for each of the SMM definitions. Relative cost differences are reported due to data restrictions.

RESULTS

Of 12,367 eligible individuals, 12,361 had complete cost data. Two hundred and eighty individuals (2.3%) had confirmed SMM events meeting CDC criteria. CDC criteria excluding transfusion alone occurred in 1.0% (n = 121) and hospital-defined SMM in 0.6% (n = 76). In adjusted models, SMM events by CDC criteria were associated with a relative cost increase of 2.45 times (95% confidence interval [CI]: 2.29-2.61) the cost of an uncomplicated delivery. SMM by CDC criteria excluding transfusion alone was associated with a relative increase of 3.26 (95% CI: 2.95-3.60) and hospital-defined SMM with a 4.19-fold (95% CI: 3.64-4.83) increase. Each additional CDC subcategory of SMM diagnoses conferred a relative cost increase of 1.60 (95% CI: 1.43-1.79).

CONCLUSION

SMM is associated with between 2.5- and 4-fold higher cost than uncomplicated deliveries.

KEY POINTS

· Severe maternal morbidity as defined by CDC criteria confers a 2.5-fold increase in delivery hospitalization costs.. · Intensive care unit admission or ≥ 4 units of blood products confer a fourfold increase in cost.. · Costs of maternal morbidity may motivate SMM review..

Attitudes, self-efficacy, and practices related to opioid risk assessment and mitigation: A comparison of health care professionals in rural communities

Background: Health care professionals (HCPs) play an important role in opioid misuse and opioid use disorder (OUD) screening/identification, mitigation, and referral to treatment. This study compared attitudes, self-efficacy, and practices related to opioid risk assessment and mitigation among pregnancy and non-pregnancy HCPs in rural communities. Methods: We conducted a secondary analysis of cross-sectional, self-report survey data of HCPs in two rural counties in southern Utah. Pregnancy HCPs were identified by a question asking whether they provide care to pregnant patients. HCPs' attitudes toward their patients with opioid misuse/OUD were measured using the Survey of Attitudes and Perceptions questionnaire. Self-efficacy and practices related to opioid risk assessment and mitigation were captured with questions asking about assessment and screening of opioid use, advisement to change opioid use behavior, and referral to treatment for OUD. We used linear regression analyses to estimate associations between HCPs' attitudes toward patients with opioid misuse/OUD and their self-efficacy and use of opioid risk assessment and mitigation practices. Results: This sample included a total of 132 HCPs, including 82 pregnancy HCPs and 50 non-pregnancy HCPs. Attitudes domains were similar among pregnancy and non-pregnancy HCPs. Among pregnancy HCPs, role adequacy (β = .48, 95% CI = .16-.80), role legitimacy (β = .72, 95% CI = .21-1.22), motivation (β = .68, 95% CI = .14-1.21), and positive task-specific self-esteem (β = 1.52, 95% CI = .70-2.35) were positively associated with more frequent use of opioid risk assessment and mitigation practices, while attitudes were not associated with these practices among non-pregnancy HCPs. Conclusions: Training initiatives that lead to improved HCP attitudes could improve opioid care management among rural pregnancy HCPs. More research is needed to determine approaches to increase the use of opioid risk assessment and mitigation practices among rural non-pregnancy HCPs.

Prenatal Nicotine or Cannabis Exposure and Offspring Neurobehavioral Outcomes

OBJECTIVE

To study the association between nicotine or cannabis metabolite presence in maternal urine and child neurodevelopmental outcomes.

METHODS

We conducted a secondary analysis of two parallel multicenter randomized controlled trials of treatment for hypothyroxinemia or subclinical hypothyroidism among pregnant individuals enrolled at 8-20 weeks of gestation. All maternal-child dyads with a maternal urine sample at enrollment and child neurodevelopmental testing were included (N=1,197). Exposure was urine samples positive for nicotine (cotinine) or cannabis 11-nor-9-carboxy-delta-9-tetrahydrocannabinol [THC-COOH]) or both metabolites. Primary outcome was child IQ at 60 months. Secondary outcomes included cognitive, motor and language, attention, behavioral and social competency, and differential skills assessments at 12, 24, 36, and 48 months. Quantile regression analysis was performed with confounder adjustment.

RESULTS

Of 1,197 pregnant individuals, 99 (8.3%) had positive cotinine samples and 47 (3.9%) had positive THC-COOH samples; 33 (2.8%) were positive for both. Groups differed in self-reported race and ethnicity, education, marital status, insurance, and thyroid status. Median IQ was similar between cotinine-exposed and -unexposed children (90 vs 95, adjusted difference in medians -2.47, 95% CI -6.22 to 1.29) and THC-COOH-exposed and -unexposed children (89 vs 95, adjusted difference in medians -1.35, 95% CI -7.76 to 5.05). In secondary outcome analysis, children with THC-COOH exposure compared with those unexposed had higher attention scores at 48 months of age (57 vs 49, adjusted difference in medians 6.0, 95% CI 1.11-10.89).

CONCLUSIONS

Neither prenatal nicotine nor cannabis exposure was associated with a difference in IQ. Cannabis exposure was associated with worse attention scores in early childhood. Longitudinal studies assessing associations between child neurodevelopmental outcomes and prenatal nicotine and cannabis exposure with a focus on timing and quantity of exposure are needed.

Treatment access for opioid use disorder in pregnancy among rural and American Indian communities

BACKGROUND

Opioid use disorder (OUD) in pregnancy disproportionately impacts rural and American Indian (AI) communities. With limited data available about access to care for these populations, this study's objective was to assess clinic knowledge and new patient access for OUD treatment in three rural U.S. counties.

MATERIAL AND METHODS

The research team used unannounced standardized patients (USPs) to request new patient appointments by phone for white and AI pregnant individuals with OUD at primary care and OB/GYN clinics that provide prenatal care in three rural Utah counties. We assessed a) clinic familiarity with buprenorphine for OUD; b) appointment availability for buprenorphine treatment; c) appointment wait times; d) referral provision when care was unavailable; and e) availability of OUD care at referral locations. We compared outcomes for AI and white USP profiles using descriptive statistics.

RESULTS

The USPs made 34 calls to 17 clinics, including 4 with publicly listed buprenorphine prescribers on the Substance Abuse and Mental Health Services Administration website. Among clinical staff answering calls, 16 (47%) were unfamiliar with buprenorphine. OUD treatment was offered when requested in 6 calls (17.6%), with a median appointment wait time of 2.5 days (IQR 1-5). Among clinics with a listed buprenorphine prescriber, 2 of 4 (50%) offered OUD treatment. Most clinics (n = 24/28, 85.7%) not offering OUD treatment provided a referral; however, a buprenorphine provider was unavailable/unreachable 67% of the time. The study observed no differences in appointment availability between AI and white individuals.

CONCLUSIONS

Rural-dwelling AI and white pregnant individuals with OUD experience significant barriers to accessing care. Improving OUD knowledge and referral practices among rural clinics may increase access to care for this high-risk population.

Indicated Opioids in Pregnancy: Guidance on Providing Comprehensive Care

In modern obstetric practice, providers will encounter patients for whom opioid use in pregnancy is reasonable or even necessary. A "one-size-fits-all" approach to the counseling and management of such patients is misguided. Understanding indications for ongoing opioid use in pregnancy is essential to patient-centered care. Specifically, recognition of the nuanced differences between opioid dependence and opioid use disorder is crucial for appropriate diagnosis, screening for common concurrent conditions, adequately counseling about individualized maternal and perinatal risks, and accurate documentation of diagnoses and medical decision-making. In this paper, we explore the current typical scenarios in which opioid use in pregnancy may be encountered, ongoing opioid prescribing should be considered, and provide a guide for the obstetric provider to navigate the antepartum, intrapartum, and postpartum periods. KEY POINTS: · Opioid use in pregnant and postpartum individuals is not rare.. · Obstetric providers may elect to assume opioid prescribing.. · Obstetric providers are positioned to optimize outcomes for the mother-infant dyad..

Buprenorphine X-waiver exemption - beyond the basics for the obstetrical provider

Buprenorphine is 1 of 3 medications approved by the US Food and Drug Administration for the treatment of opioid use disorder, and practitioners must obtain a federal waiver to prescribe buprenorphine. Until recently, physicians and advanced practice clinicians were required to complete 8 and 24 hours of training, respectively, before applying for this waiver and to provide psychosocial services when prescribing buprenorphine to ≤30 patients. The US Department of Health and Human Services announced in April 2021 that eligible providers would be exempt from the educational requirement for certification, making the waiver more accessible for those intending to prescribe to ≤30 patients. Here, we reviewed the historic background to the exemption and provided practical guidelines to practitioners caring for obstetrical patients with opioid use disorder who are considering applying for the waiver for the first time. Because the educational requirements will no longer be required for X-waiver application, we reviewed fundamental topics and challenging scenarios that are often reviewed in certification courses.

Development of an unannounced standardized patient protocol to evaluate opioid use disorder treatment in pregnancy for American Indian and rural communities

BACKGROUND

Opioid use disorder (OUD) disproportionately impacts rural and American Indian communities and has quadrupled among pregnant individuals nationwide in the past two decades. Yet, limited data are available about access and quality of care available to pregnant individuals in rural areas, particularly among American Indians (AIs). Unannounced standardized patients (USPs), or "secret shoppers" with standardized characteristics, have been used to assess healthcare access and quality when outcomes cannot be measured by conventional methods or when differences may exist between actual versus reported care. While the USP approach has shown benefit in evaluating primary care and select specialties, its use to date for OUD and pregnancy is very limited.

METHODS

We used literature review, current practice guidelines for perinatal OUD management, and stakeholder engagement to design a novel USP protocol to assess healthcare access and quality for OUD in pregnancy. We developed two USP profiles-one white and one AI-to reflect our target study area consisting of three rural, predominantly white and AI US counties. We partnered with a local community health center network providing care to a large AI population to define six priority outcomes for evaluation: (1) OUD treatment knowledge among clinical staff answering telephones; (2) primary care clinic facilitation and provision of prenatal care and buprenorphine treatment; (3) appropriate completion of evidence-based screening, symptom assessment, and initial steps in management; (4) appropriate completion of risk factor screening/probing about individual circumstances that may affect care; (5) patient-directed tone, stigma, and professionalism by clinic staff; and (6) disparities in care between whites and American Indians.

DISCUSSION

The development of this USP protocol tailored to a specific environment and high-risk patient population establishes an innovative approach to evaluate healthcare access and quality for pregnant individuals with OUD. It is intended to serve as a roadmap for our own study and for future related work within the context of substance use disorders and pregnancy.

Experiences of Nursing Professionals Working With Women Diagnosed With Opioid Use Disorder and Their Newborns: Burnout and the Need for Support

BACKGROUND

As the rate of opioid use in pregnancy escalates, there are a growing number of women diagnosed with opioid use disorder (OUD) and their newborns being cared for in inpatient settings.

PURPOSE

In this study, we sought to better understand the experiences of nurses and nursing assistants working with women diagnosed with OUD and their newborns. By identifying the needs of nurses and nursing assistants, the findings from this study may contribute to reductions in stigma and improved patient care.

METHODS

Nurses and nursing assistants were recruited from a postpartum unit at a large urban hospital in Utah. Participants (n = 30) attended up to 4 semistructured focus groups. We utilized Braun and Clarke's 6-phase approach to thematic analysis to analyze transcribed interviews.

FINDINGS/RESULTS

Themes identified during the data analysis process included negative feelings and reactions toward patients; preferential concern for the newborn over maternal well-being; and identification of organizational and training needs to overcome these challenges.

IMPLICATIONS FOR PRACTICE

These findings identify strategies for addressing challenges faced by nurses and nursing assistants in caring for women diagnosed with OUD and their newborns.

IMPLICATIONS FOR RESEARCH

Future research should examine the effectiveness of approaches to reduce behaviors influenced by stigma among nurses and nursing assistants working with women diagnosed with OUD and their newborns, as well as employee and patient satisfaction, and long-term health outcomes.

Trends in Opioid and Psychotropic Prescription in Pregnancy in the United States From 2001 to 2015 in a Privately Insured Population : A Cross-sectional Study

BACKGROUND

Opioid and psychotropic prescriptions are common during pregnancy. Little is known about coprescriptions of both medications in this setting.

OBJECTIVE

To describe opioid prescription among women who are prescribed psychotropics compared with women who are not.

DESIGN

Cross-sectional study.

SETTING

U.S. commercial insurance beneficiaries from MarketScan (2001 to 2015).

PARTICIPANTS

Pregnant women at 22 weeks' gestation or greater who were insured continuously for 3 months or more before pregnancy through delivery.

MEASUREMENTS

Opioid prescription, dosage thresholds (morphine milligram equivalents [MME] of ≥50/day and ≥90/day), number of opioid agents (≥2), and duration (≥30 days) among those with and without prescription of psychotropics, from 2011 to 2015.

RESULTS

Among 958 980 pregnant women, 10% received opioids only, 6% psychotropics only, and 2% opioids with coprescription of psychotropics. Opioid prescription was higher among women prescribed psychotropics versus those who were not (26.5% vs. 10.7%). From 2001 to 2015, psychotropic prescription overall increased from 4.4% to 7.6%, opioid prescription without coprescription of psychotropics decreased from 11.9% to 8.4%, and opioids with coprescription decreased from 28.1% to 22.0%. Morphine milligram equivalents of 50 or greater per day decreased for women with and without coprescription (29.6% to 17.3% and 22.8% to 18.5%, respectively); MME of 90 or greater per day also decreased in both groups (15.0% to 4.7% and 11.5% to 4.2%, respectively). Women prescribed opioids only were more likely to have an antepartum hospitalization compared with those with neither prescription, as were women with coprescription versus those prescribed psychotropics only. Compared with those prescribed opioids only, women with coprescriptions were more likely to exceed MME of 90 or greater per day and to be prescribed 2 or more opioid agents and for 30 days or longer. Number and duration of opioids increased with benzodiazepine and gabapentin coprescription.

LIMITATION

Inability to determine appropriateness of prescribing or overdose events.

CONCLUSION

Opioids are frequently coprescribed with psychotropic medication during pregnancy and are associated with antepartum hospitalization. A substantial proportion of pregnant women are prescribed opioids at doses that increase overdose risk and exceed daily recommendations.

PRIMARY FUNDING SOURCE

None.

Early lessons from maternal mortality review committees on drug-related deaths-time for obstetrical providers to take the lead in addressing addiction

Problem:

In the United States, maternal mortality review committees (MMRC) are providing compelling data that drug-related deaths are emerging as a leading cause of pregnancy-associated death (death during pregnancy or up to a year postpartum). Recommendations from the MMRC consistently highlight screening all pregnant and postpartum women for drug use and improving access to evidence-based substance use disorder and mental health treatment. Unfortunately, many providers lack the confidence, skills and necessary resources to screen for substance use, provide basic behavioral health services or facilitate referral to high-quality services in their clinical settings. Our profession’s collective lack of response to a leading cause of maternal death represents a missed opportunity for potentially life-saving interventions.

A Solution:

We call on our fellow obstetrician gynecologists to incorporate the lessons learned from MMRC and integrate addiction assessment and treatment into prenatal and postpartum care. Provider level integration of behavioral health services is, however, insufficient to fully address the magnitude of drug-related maternal deaths in the US. We, therefore, ask colleagues to address the structural/systemic barriers to care identified in MMRC. By doing so, we can prevent drug-related maternal deaths.

Addressing opioid use disorder among rural pregnant and postpartum women: a study protocol

BACKGROUND

Opioid use disorder (OUD) among women delivering at a hospital has increased 400% from 1999-2014 in the United States. From the years 2007 to 2016, opioid-related mortality during pregnancy increased over 200%, and drug-overdose deaths made up nearly 10% of all pregnancy-associated mortality in 2016 in the US. Disproportionately higher rates of neonatal opioid withdrawal syndrome (NOWS) have been reported in rural areas of the country, suggesting that perinatal OUD is a pressing issue among these communities. There is an urgent need for comprehensive, evidence-based treatment services for pregnant women experiencing OUD. The purpose of this article is to describe a study protocol aimed at developing and evaluating a perinatal OUD curriculum, enhancing evidence-based perinatal OUD treatment in a rural setting, and evaluating the implementation of such collaborative care for perinatal OUD.

METHODS

This two-year study employed a one group, repeated measures, hybrid type-1 effectiveness-implementation design. This study delivered interventions at 2 levels, both targeting improvement of care for pregnant women with OUD. The first area of focus was at the community healthcare provider-level, which aimed to evaluate the acceptability and feasibility of perinatal OUD education across time and to improve provider education by increasing knowledge specific to: MOUD provision; screening, brief intervention, and referral to treatment (SBIRT) utilization; and NOWS treatment. The second area of intervention focus was at the patient-level, which assessed the preliminary effect of perinatal OUD provider education in promoting illicit opioid abstinence and treatment engagement among pregnant women with OUD. We adopted constructs from the Consolidated Framework for Implementation Research (CFIR) to assess contextual factors that may influence implementation, and the Reach, Effectiveness, Adoption, Implementation, and Maintenance (RE-AIM) model to comprehensively evaluate implementation outcomes.

DISCUSSION

This article presents the protocol of an implementation study that is employing the CFIR and RE-AIM frameworks to implement and evaluate a perinatal OUD education and service coordination program in two rural counties. This protocol could serve as a model for clinicians and researchers seeking to implement improvements in perinatal care for women with OUD in other rural communities.

A pilot multisite study of patient navigation for pregnant women with opioid use disorder

The opioid crisis continues to affect pregnant and postpartum women the United States, with the number of pregnant women diagnosed with opioid use disorder (OUD) quadrupling over the last decade. The associated increase in morbidity and mortality among mother and baby warrants prompt, targeted intervention efforts that improve engagement, linkage of care, and treatment retention. Patient navigation (PN) is a chronic care intervention that can directly address this need by helping women identify medical, behavioral, and psychosocial care goals. Moreover, PN can assist women in preparing for, engaging in, and maintaining patient participation in necessary services. Specifically, PN includes strengths-based case management, 1-1 clinical support, motivational interviewing, and addiction-relapse prevention programming. The objective of this article is to present the study protocol of a pilot multisite randomized clinical trial, entitled: Optimizing Pregnancy and Treatment Interventions for Moms 2.0 (OPTI-Mom 2.0; NCT03833245). In this study, we build upon a proof-of-concept study, employing evidence-informed frameworks for protocol and intervention expansion in order to construct a PN intervention tailored for pregnant women with OUD in central Utah and southwestern Pennsylvania. Our protocol provides an initial framework of a potentially impactful intervention and may guide development of future programs. Importantly, this study further establishes the evidence-base-with potential to ameliorate serious adverse opioid-related outcomes and improve health for women and their children.

Impact of Preclinical Labor and Delivery Shadowing on Student Perceptions of Obstetrics and Gynecology as a Specialty and Possible Career: A Prospective Cohort

Objective  The purpose of this study was to determine the impact of preclinical shadowing on student interest and perceptions of obstetrics and gynecology (OBGYN). Methods  We enrolled a prospective cohort of preclinical medical students who shadowed on labor and delivery (L&D). Students sent electronic surveys a week prior (presurvey), the week after (postsurvey), and three months after shadowing (far-survey). Responses compared using descriptive statistics. We analyzed common themes of free text responses. Results  From July 2016 to April 2017, 41 students shadowed on L&D; 81% were female. Eighty percent responded to at least one survey, 37% completed all surveys, (presurvey: 76%, postsurvey: 51%, and far-survey: 46%). Prior to shadowing, 10% (3/31) planed a career in OBGYN compared with 24% (5/21) after shadowing ( p  = 0.42). Over 50% of students described the people and procedures as altering their perceptions of OBGYN in a positive way. Common themes explaining this change included: culture ( n  = 4), team interactions ( n  = 4), seeing deliveries ( n  = 3), and hands-on experiences ( n  = 3). Three months after shadowing, 79% described the experience as very worthwhile. Eighty-nine percent would recommend the experience to a friend not interested in OBGYN and 100% stated they would shadow again. Discussion  Although shadowing may not increase students' desire to pursue OBGYN, it is nearly universally felt to be worthwhile and improves perceptions of the field.

Intergenerational transmission of emotion dysregulation: Part I. Psychopathology, self-injury, and parasympathetic responsivity among pregnant women

The World Health Organization recently reported that maternal mental health is a major public health concern. As many as one in four women suffer from psychiatric disorders at some point during pregnancy or the first postpartum year. Furthermore, self-injurious thoughts and behaviors (SITBs) represent one of the leading causes of death among women during this time. Thus, efforts to identify women at risk for serious forms of psychopathology and especially for SITBs are of utmost importance. Despite this urgency, current single-diagnostic approaches fail to recognize a significant subset of women who are vulnerable to perinatal stress and distress. The current study was among the first to investigate emotion dysregulation-a multilevel, transdiagnostic risk factor for psychopathology-and its associations with stress, distress, and SITBs in a sample of pregnant women (26-40 weeks gestation) recruited to reflect a range of emotion dysregulation. Both self-reported emotion dysregulation and respiratory sinus arrhythmia, a biomarker of emotion dysregulation, demonstrated expected associations with measures of mental health, including depression, anxiety, borderline personality pathology, and SITBs. In addition, self-reported emotion dysregulation was associated with blunted respiratory sinus arrhythmia responsivity to an ecologically valid infant cry task. Findings add to the literature considering transdiagnostic risk during pregnancy using a multiple-levels-of-analysis approach.

The Effect of Blood Loss on Cefazolin Levels in Women Undergoing Cesarean Delivery

OBJECTIVE

To quantify the effects of operative blood loss during cesarean on tissue and plasma cefazolin concentrations.

STUDY DESIGN

This was a prospective observational study of singleton pregnancies undergoing scheduled cesarean between 34 and 40 weeks. Cefazolin administered prior to skin incision. Maternal plasma samples were obtained (Time 1[T1]: immediately, T2: 20 minutes, T3: 40 minutes, and T4: 60 minutes after cefazolin infusion). Subcutaneous adipose tissue sampled before and after fascia. Primary outcome was subcutaneous adipose cefazolin level after fascial closure. Formal quantitative blood loss (QBL) performed. Women with higher QBL, those at/above 75% of QBL in this population, were compared with those with lower QBL (QBL below 75%). Data analyzed using bivariable statistics.

RESULTS

Ninety-two women were screened, 32 were eligible, and 20 enrolled. Median QBL was 630 mL (interquartile range [IQR]: 473-818) and 1,160 mL (IQR: 1,000-1,560) in the low and high QBL groups, respectively. Demographics and operative characteristics were similar. Median adipose cefazolin level after fascial closure did not differ between the groups (3.5 vs. 3.9 μg/g, p = 0.75). No differences in maternal plasma cefazolin concentrations between the groups at any time point or in pharmacokinetic parameters were seen.

CONCLUSION

Intraoperative maternal plasma concentrations and adipose levels of cefazolin are similar between women with high and low blood loss at the time of cesarean delivery.

Pregnancy-Associated Death in Utah: Contribution of Drug-Induced Deaths

OBJECTIVE

Drug-induced deaths, defined as intentional or unintentional consumption of illicit substances or diverted medications leading to death, are the leading cause of death for reproductive-age women in the United States. Our objective was to describe pregnancy-associated deaths attributed to drug-induced causes to identify opportunities for intervention.

METHODS

Using the Utah Perinatal Morality Review Committee database, we performed a retrospective cohort study of all pregnancy-associated deaths-death of a woman during pregnancy or within 1 year from the end of pregnancy-from 2005 to 2014. We performed a detailed descriptive analysis of women with drug-induced deaths. We compared characteristics of women with drug-induced and other pregnancy-associated deaths.

RESULTS

From 2005 to 2014, 136 pregnancy-associated deaths were identified. Drug-induced death was the leading cause of pregnancy-associated death (n=35, 26%) and 89% occurred in the postpartum period. More specifically, those with a drug-induced death were more likely to die in the late postpartum period, defined as death occurring within 43 days to 1 year of the end of the pregnancy, (n=28/35, 80%) compared with women whose deaths were from other pregnancy-associated causes (n=34/101, 34%) (P<.001). The majority of drug-induced deaths were attributed to opioids (n=27/35, 77%), prescription opioids (n=21/35, 60%), and polysubstance use (n=29/35, 83%). From 2005 to 2014, the pregnancy-associated mortality ratio increased 76%, from 23.3 in 2005 to 41.0 in 2014. During this same time period, the drug-induced pregnancy-associated mortality ratio increased 200%, from 3.9 in 2005 to 11.7 in 2014.

CONCLUSION

Drug-induced death is the leading cause of pregnancy-associated death in Utah and occurs primarily in the late postpartum period. Interventional studies focused on identifying and treating women at risk of drug-induced death are urgently needed.

Stimulant Use in Pregnancy: An Under-recognized Epidemic Among Pregnant Women

Stimulant use, including cocaine, methamphetamines, ecstasy, and prescription stimulants, in pregnancy is increasingly common. In the United States, stimulants are the second most widely used and abused substances during pregnancy and pregnant women using stimulants in pregnancy are at increased risk of adverse perinatal, neonatal, and childhood outcomes. In this review, we describe the pharmacology, pathophysiology, and epidemiology of stimulants, summarize the maternal and neonatal effects of perinatal stimulant use, and outline treatment options for stimulant use disorders among pregnant women. Development of effective treatment strategies for stimulant use disorders identified among pregnant women are urgently needed.

Child Neurodevelopmental Outcomes by Prepregnancy Body Mass Index and Gestational Weight Gain

OBJECTIVE

To study the association of prepregnancy body mass index (BMI) and gestational weight gain with child neurodevelopmental outcomes.

METHODS

We performed a secondary analysis of data from two parallel, multicenter, randomized, double-blind, placebo-controlled thyroxine replacement trials in pregnant women with either hypothyroxinemia or subclinical hypothyroidism who delivered at term. Body mass index was categorized as normal (18.5-24.9), overweight (25.0-29.9), or obese (30 or greater). We also evaluated early (20 weeks of gestation or less), late (greater than 20 weeks of gestation), and total gestational weight gain and categorized gestational weight gain as inadequate, adequate, and excessive per 2009 Institute of Medicine guidelines. Neurodevelopmental outcomes included 5-year Wechsler Preschool and Primary Scale of Intelligence and 3-year Differential Ability Scales-II. Linear and logistic regression analyses were performed and adjusted for maternal age, race-ethnicity, education, insurance status, parity, smoking and alcohol use, thyroid status (subclinical hypothyroidism or hypothyroxinemia), treatment group, gestational age at delivery, and neonatal sex.

RESULTS

Of the 948 women included, 380 (40%), 305 (32%), and 263 (28%) had normal, overweight, and obese prepregnancy BMI, respectively. A total of 106 (11%), 212 (22%), and 630 (66%) of women had inadequate, adequate, and excessive total rates of gestational weight gain, respectively. Maternal differences among the BMI categories included race-ethnicity, education, insurance type, parity, and thyroid status (all P<.01), whereas the gestational weight gain groups only differed by parity (P<.001). In unadjusted analysis, children of obese (93.2±12.8; 88.5±13.3) and overweight (94.1±15.6; 89.6±16.0) women had lower Wechsler Preschool and Primary Scale of Intelligence and Differential Ability Scales-II scores, respectively, than normal-weight women (97.4±15.4; 93.9±16.0; P<.001 for all comparisons); however, in adjusted analysis, there were no differences in neurodevelopmental outcomes by maternal BMI. The association was primarily accounted for by race-ethnicity and education. In unadjusted and adjusted analyses, there were no differences in neurodevelopmental outcomes by adequacy of early, late, or total gestational weight gain.

CONCLUSION

In women with either subclinical hypothyroidism or hypothyroxinemia, neither prepregnancy BMI nor gestational weight gain was associated with neurodevelopmental outcomes among children born at term in adjusted analyses.
