BACKGROUND: Health care providers are a key source of reports of infants to child welfare related to birthing peoples substance use. Many of these reports are overreports, or reports that exceed what is legally mandated, and reflect racial bias. We developed and evaluated a webinar for health professionals to address overreporting related to birthing peoples substance use. METHODS: This evaluation study collected data from health professionals registering to participate in a professional education webinar about pregnancy, substance use, and child welfare reporting. It collected baseline data upon webinar registration, immediate post-webinar data, and 6 month follow-up data. Differences in both pre-post-and 6 month follow-up data were used to examine changes from before to after the webinars in beliefs, attitudes, and practices related to pregnant and birthing people who use drugs and child welfare reporting. RESULTS: 592 nurses, social workers, physicians, public health professionals, and other health professionals completed the baseline survey. More than half of those completing the baseline survey (n = 307, 52%) completed one or both follow-up surveys. We observed statistically significant changes in five of the eleven opioid attitudes/beliefs and in four of the nine child welfare attitudes/beliefs from baseline to follow-ups, and few changes in control statements, i.e. beliefs we did not expect to change based on webinar participation. All of the changes were in the direction of less support for child welfare reporting. In particular, the proportion agreeing with the main evaluation outcome of I would rather err on the side of overreporting to child welfare than underreporting to child welfare decreased from 41% at baseline to 28% and 31% post-webinar and at 6-month follow up (p = 0.001). In addition, fewer participants endorsed reporting everyone at the 6 month follow-up than at baseline (12% to 22%) and more participants endorsed reporting no one at t

INTRODUCTION: An increased incidence of maternal opioid use disorder (OUD) and neonatal abstinence syndrome (NAS) has prompted recommendations supporting a dyadic approach to care for birthing persons and their infants. However, there are no consensus guidelines outlining how the dyad is clinically defined. METHODS: To examine how the opioid-exposed birthing person-infant dyad has been defined for purposes of data collection and research, a literature review applying the RAND/UCLA Appropriateness Method was conducted. RESULTS: The search yielded 320 abstracts, with 110 articles identified as having a dyadic focus. While no articles included a specific definition for the dyad, 33 (30%) contained a descriptive reference to the birthing person-infant dyad. Thematic analysis revealed eight recurring elements characteristic of the dyad: (1) engagement, (2) communication, (3) bonding, (4) attachment, (5) mutual responsiveness, (6) reciprocity, (7) synchrony, and (8) attunement. Integrating these elements revealed the interactional relationship between the opioid-exposed birthing person and infant as the foundational principle that defines the dyad. DISCUSSION: This definition shifts the focus of the opioid-exposed dyad from two individual patient populations to an interactional relationship that has broad applicability for clinical use, public health data collection, and research considerations.

This protocol outlines a proposed scoping review to characterize evidence on implementation and quality improvement (QI) strategies that aim to improve equitable, evidence-informed care delivery for pregnant and birthing people with substance use disorder (SUD) in acute care. Untreated SUD during pregnancy is associated with an increased risk of overdose and severe maternal morbidity. Acute care settings are one important place to deliver equitable, evidence-informed clinical care. While clinical practice guidelines for substance use treatment and care of pregnant and birthing people with SUD exist, there are gaps in implementation. Our population of interest is pregnant and birthing people with SUD in an acute care setting. We will include US-based studies that describe or evaluate implementation or QI strategies, including experimental, observational, and descriptive studies published from 2016 to 2023. The proposed scoping review will be conducted in accordance with JBI methodology for scoping reviews and registered at OSF (registration number: BC4VZ). We will search MEDLINE (PubMed), CINAHL Complete (EBSCO), Scopus (Elsevier), and APA PsychInfo (Ovid) for published studies. Conference proceedings and Perinatal Quality Collaborative websites will be searched for grey literature. Two reviewers will independently screen then extract studies that meet inclusion criteria using a data extraction tool. The completion of this scoping review will help illuminate strengths and gaps in research and practice that aim to inform substance use treatment and care in acute care settings for pregnant and birthing people with SUD.

Substance use in pregnant and parenting persons is common, yet still underdiagnosed. Substance use disorder (SUD) is one of the most stigmatized and undertreated chronic medical conditions, and this is exacerbated in the perinatal period. Many providers are not sufficiently trained in screening or treatment for substance use, so gaps in care for this population persist. Punitive policies towards substance use in pregnancy have proliferated, lead to decreased prenatal care, do not improve birth outcomes, and disproportionately impact Black, Indigenous, and other families of color. We discuss the importance of understanding the unique barriers of pregnancy-capable persons and drug overdose as one of the leading causes of maternal death in the United States. We highlight the principles of care from the obstetrician-gynecologist perspective including care for the dyad, person-centered language, and current medical terminology. We then review treatment of the most common substances, discuss SUD during the birthing hospitalization, and highlight the high risk of mortality in the postpartum period.

Substance use disorders are a common and treatable condition among pregnant and parenting people. Social, self, and structural stigma experienced by this group represent a barrier to harm reduction, treatment utilization, and quality of care. We examine features of research dissemination that may generate or uphold stigmatization at every level for pregnant and parenting individuals affected by substance use disorder and their children. We explore stigma reduction practices within the research community that can increase uptake of evidence-based treatment programs and prevent potential harm related to substance use in pregnant and parenting people. The strategies we propose include: (1) address researcher stereotypes, prejudice, and misconceptions about pregnant and parenting people with substance use disorder; (2) engage in interdisciplinary and transdisciplinary collaborations that engage with researchers who have lived experience in substance use; (3) use community-based approaches and engage community partners, (4) address stigmatizing language in science communication; (5) provide contextualizing information about the social and environmental factors that influence substance use among pregnant and parenting people; and (6) advocate for stigma-reducing policies in research articles and other scholarly products.

ObjectivesSome states, including Massachusetts, require automatic filing of child abuse and neglect for substance-exposed newborns, including infants exposed in-utero to clinician-prescribed medications to treat opioid use disorder (MOUD). The aim of this article is to explore effects of these mandated reporting policies on pregnant and postpartum people receiving MOUD.MethodsWe used modified grounded research theory, literature findings, and constant comparative methods to extract, analyze and contextualize perinatal experiences with child protection systems (CPS) and explore the impact of the Massachusetts mandated reporting policy on healthcare experiences and OUD treatment decisions. We drew from 26 semi-structured interviews originally conducted within a parent study of perinatal MOUD use in pregnancy and the postpartum period.ResultsThree themes unique to CPS reporting policies and involvement emerged. First, mothers who received MOUD during pregnancy identified mandated reporting for prenatally prescribed medication utilization as unjust and stigmatizing. Second, the stress caused by an impending CPS filing at delivery and the realities of CPS surveillance and involvement after filing were both perceived as harmful to family health and wellbeing. Finally, pregnant and postpartum individuals with OUD felt pressure to make medical decisions in a complex environment in which medical recommendations and the requirements of CPS agencies often compete.Conclusions for practiceUncoupling of OUD treatment decisions in the perinatal period from mandated CPS reporting at time of delivery is essential. The primary focus for families affected by OUD must shift from surveillance and stigma to evidence-based treatment and access to supportive services and resources.

There is a fundamental disconnect between the optimal management of addiction in general and care delivery in pregnancy and postpartum. Addiction is a chronic condition requiring some degree of management across the life course. Yet, in the US, reproductive care is episodic and centers more on pregnancy than at other stages of the reproductive life course. Pregnancy is prioritized in access to insurance as almost all pregnant people are Medicaid eligible but access ends at varying points postpartum. This results in a structural mismatch: the episodic management of the chronic condition of addiction only within gestational periods. Though people with substance use disorder (SUD) may access care in pregnancy, treatment attrition is common postpartum. Postpartum is a time of increased vulnerabilities where insurance churn and newborn caretaking responsibilities collide in a context of care withdrawal from the health system and health providers. In part in consequence, return to use, SUD recurrence, overdose, and overdose death are more common postpartum than in pregnancy, and drug deaths have become a leading cause of maternal deaths in the US. This review addresses interventions to support engagement in addiction care postpartum. We begin with a scoping review of model programs and evidence-informed interventions that have been shown to increase continuation of care postpartum. We then explore the realities of contemporary care through a review of clinical and ethical principles, with particular attention to harm reduction. We conclude with suggestions of strategies (clinical, research, and policy) to improve care postpartum and highlight potential pitfalls in the uptake of evidence-based and person-centered services.

BACKGROUND: Medical professionals are key components of child maltreatment surveillance. Updated estimates of reporting rates by medical professionals are needed. METHODS: We use the National Child Abuse and Neglect Data System (2000-2019) to estimate rates of child welfare investigations of infants stemming from medical professional reporting to child welfare agencies. We adjust for missing data and join records to population data to compute race/ethnicity-specific rates of infant exposure to child welfare investigations at the state-year level, including sub-analyses related to pregnant/parenting peoples substance use. RESULTS: Between 2010 and 2019, child welfare investigated 2.8 million infants; ∼26% (n=731,705) stemmed from medical professionals reports. Population-adjusted rates of these investigations stemming doubled between 2010 and 2019 (13.1-27.1 per 1000 infants). Rates of investigations stemming from medical professionals reports increased faster than did rates for other mandated reporters, such as teachers and police, whose reporting remained relatively stable. In 2019, child welfare investigated ∼1 in 18 Black (5.4%), 1 in 31 Indigenous (3.2%), and 1 in 41 White infants (2.5%) following medical professionals reports. Relative increases were similar across racial groups, but absolute increases differed, with 1.3% more of White, 1.7% of Indigenous, and 3.1% of Black infants investigated in 2019 than 2010. Investigations related to substance use comprised ∼35% of these investigations; in some states, this was almost 80%. DISCUSSION: Rates of child welfare investigations of infants stemming from medical professional reports have increased dramatically over the past decade with persistent and notable racial inequities in these investigations.

OBJECTIVES: To describe the characteristics of individuals undergoing toxicology testing at delivery for a sole indication of cannabis use and to evaluate the rate of unexpected positive toxicology testing results among this cohort. METHODS: This retrospective cohort study included dyads with a maternal history of cannabis use who underwent peripartum toxicology testing between 2016 and 2020 at 5 birthing hospitals in Massachusetts. We collected information on maternal demographic characteristics and toxicology test results and reviewed records of dyads with unexpected positive results to identify additional social risk factors and clinical outcomes. RESULTS: Of 60 608 live births reviewed, 1924 dyads underwent toxicology testing, including 614 (31.9%) for a sole indication of cannabis use. Significantly greater percentages of patients in the cannabis cohort were <25 years old (32.4% vs 6.1% of the birthing population, P <.001), non-Hispanic Black (32.4% vs 8.1%, P < .001), Hispanic or Latino (30.5% vs 15.5%), American Indian/Alaskan (0.7% vs 0.1%), and publicly insured (39.9% vs 15.6%, P <.001). Eight of the 614 dyads (1.3%) had an unexpected positive toxicology test result, including 2 (0.3%) unexpectedly positive for opioids. Seven dyads (1.1%) had false positive test results for unexpected substances. Only 1 test result changed clinical management; a urine test positive for opioids prompted monitoring (but not medication) for neonatal opioid withdrawal syndrome. CONCLUSIONS: Toxicology testing of patients for a sole indication of cannabis use, without other risk factors, may be of limited utility in elucidating other substance use and may exacerbate existing disparities in perinatal outcomes.

ObjectivesThe goal of this study was to evaluate the association between pregnancy intentions and substance use in early pregnancy among pregnant women receiving prenatal care in a large, integrated healthcare system.MethodsThe sample comprised 29,787 Kaiser Permanente Northern California pregnant women (12.1% aged <25, 36.4% non-Hispanic White) screened for prenatal substance use in 2018 via a self-reported questionnaire and urine toxicology test given as part of standard prenatal care (at ∼8 weeks gestation). Multivariable logistic regression models tested for associations of pregnancy intentions with prenatal substance use (any use and specific substances) by self-report and/or a positive urine toxicology test.ResultsAdjusting for covariates, women with an unintended pregnancy (23.9% of the sample) had higher odds of any prenatal substance use than women with an intended pregnancy (28.8% vs 16.1%; adjusted odds ratio [aOR] = 1.80, 95% confidence interval [CI]:1.67-1.93). Having an unintended pregnancy was also associated with higher odds of using alcohol (14.4% vs 10.4%; aOR = 1.73, 95%CI:1.59-1.89), cannabis (15.6% vs 5.6%; aOR = 1.91, 95%CI:1.73-2.11), nicotine (3.8% vs 1.3%; aOR = 2.33, 95%CI:1.92-2.82), pain medication (2.3% vs 1.2%; aOR = 1.64, 95%CI:1.32-2.03), and stimulants (0.8% vs 0.3%; aOR = 1.85, 95%CI:1.23-2.79) early in pregnancy.DiscussionHaving an unintended pregnancy was associated with higher odds of substance use during early pregnancy. Connecting women of reproductive age with health education about pregnancy prevention and recognition of early signs of pregnancy, effective contraception, and early screening and interventions for prenatal substance use may help to reduce prenatal substance use and its associated consequences.

OBJECTIVES: Disparities in substance use disorder (SUD) treatment use persist across groups, including gender. Using a gender-informed approach to expand treatment capacity and reduce barriers to treatment engagement is vital. We examined SUD treatment need and receipt among people with SUD in the United States, by gender, and assessed gender-specific sociodemographic factors associated with unmet need for SUD treatment and reported treatment barriers. METHODS: We conducted an analysis of data among adults aged ≥18 with a past-year SUD from the National Survey on Drug Use and Health (2015-2018). We computed population-adjusted frequencies and proportions for SUD treatment need and receipt and assessed gender differences. Multivariate logistic regression assessed gender-specific sociodemographic variables associated with SUD treatment receipt. RESULTS: Among adults with a past-year SUD, 63.4% were men and 36.6% were women (P < .001), only 10.6% received SUD treatment, and a greater percentage of women than men needed treatment for opioid use disorder (11.9% vs 9.9%; P = .002). Receipt of SUD treatment was lowest among women with alcohol use disorder followed by men with alcohol use disorder (7.5% vs 8.9%; P = .052). Non-Latinx Black men had fewer than half the adjusted odds of receiving SUD treatment than non-Latinx White men (adjusted odds ratio [aOR] = 0.44; 95% CI, 0.27-0.71). Latinx women (aOR = 0.37; 95% CI, 0.18-0.73) and non-Latinx Black women (aOR = 0.51; 95% CI, 0.27-0.94) had significantly lower odds of receiving SUD treatment than non-Latinx White women. CONCLUSIONS: As public health efforts target expanding SUD treatment capacity and addressing disparities in use of SUD treatment, interventions informed by gender and culture should be prioritized.

INTRODUCTION: Medications to treat opioid use disorder (MOUD) during pregnancy and in the postpartum period remain underutilized. A need exists to enhance our understanding of modifiable factors, facilitators, and barriers to MOUD utilization and adherence in the perinatal period to improve maternal and child outcomes. METHODS: The study conducted semi-structured qualitative interviews with recently pregnant people with opioid use disorder (OUD) to explore experiences as a pregnant and/or parenting person with OUD, perceptions of enabling factors and barriers to treatment utilization, incentivizing factors for maintaining adherence, and acceptability of ongoing supports to sustain treatment adherence. The study team used constant comparative methods to analyze transcripts and develop the codebook. The team double coded the transcripts, with an overall kappa coefficient of 0.88. RESULTS: The study team interviewed twenty-six women on average 10.1 months after delivery. All women had some prior experience using MOUD. Four unique themes emerged as barriers to medication utilization and adherence in the perinatal period: 1) Lack of agency and autonomy surrounding medication decisions because pregnancy or parenting status affected treatment adherence; 2) Hesitancy to use MOUD to minimize risk of newborn withdrawal; 3) Concern about increased scrutiny and potential loss of custody due to mandated child protective services reporting for opioid-exposure at delivery in Massachusetts; and 4) Perception that treatment environments, particularly methadone clinics, did not provide gender-responsive or equitable care, and standardized, inflexible visit regulations were particularly difficult to comply with in the early postpartum period. CONCLUSIONS: Women with OUD experienced a double bind when making perinatal treatment decisions, describing pressure to use MOUD with negative consequences after delivery. Key areas for possible intervention emerged from interviews. These ar

BackgroundOpioid agonist therapy is strongly recommended for pregnant persons with opioid use disorder. Buprenorphine may be associated with more favorable neonatal and maternal outcomes than methadone, but existing data are limited.MethodsWe conducted a cohort study involving pregnant persons who were enrolled in public insurance programs in the United States during the period from 2000 through 2018 in which we examined outcomes among those who received buprenorphine as compared with those who received methadone. Exposure to the two medications was assessed in early pregnancy (through gestational week 19), late pregnancy (gestational week 20 through the day before delivery), and the 30 days before delivery. Risk ratios for neonatal and maternal outcomes were adjusted for confounders with the use of propensity-score overlap weights.ResultsThe data source for the study consisted of 2,548,372 pregnancies that ended in live births. In early pregnancy, 10,704 pregnant persons were exposed to buprenorphine and 4387 to methadone. In late pregnancy, 11,272 were exposed to buprenorphine and 5056 to methadone (9976 and 4597, respectively, in the 30 days before delivery). Neonatal abstinence syndrome occurred in 52.0% of the infants who were exposed to buprenorphine in the 30 days before delivery as compared with 69.2% of those exposed to methadone (adjusted relative risk, 0.73; 95% confidence interval [CI], 0.71 to 0.75). Preterm birth occurred in 14.4% of infants exposed to buprenorphine in early pregnancy and in 24.9% of those exposed to methadone (adjusted relative risk, 0.58; 95% CI, 0.53 to 0.62); small size for gestational age in 12.1% and 15.3%, respectively (adjusted relative risk, 0.72; 95% CI, 0.66 to 0.80); and low birth weight in 8.3% and 14.9% (adjusted relative risk, 0.56; 95% CI, 0.50 to 0.63). Delivery by cesarean section occurred in 33.6% of pregnant persons exposed to buprenorphine in early pregnancy and 33.1% of those exposed to methadone (adjusted relativ

We previously observed that the nine-member family of autotransported polymorphic membrane proteins (Pmps) of Chlamydia trachomatis is variably expressed in cell culture. Additionally, C. trachomatis-infected patients display variable Pmp-specific serum antibody profiles indirectly suggesting expression of unique Pmp profiles is an adaptive response to host-specific stimuli during infection. Here, we propose that the host response to Pmps and other outer surface proteins may correlate with disease severity. This study tests this hypothesis using an ELISA that measures serum IgG antibodies specific for the nine C. trachomatis Pmp subtypes and four immunodominant antigens (MOMP, OmcB, Hsp60, ClpP) in 265 participants of the Chlamydia Adolescent/Young Adult Reproductive Management (CHARM) cohort. More C. trachomatis-infected females displayed high Pmp-specific antibody levels (cut-off Indexes) than males (35.9%-40.7% of females vs. 24.2%-30.0% of males), with statistical significance for PmpC, F and H (P < 0.05). Differences in Pmp-specific antibody profiles were not observed between C. trachomatis-infected females with a clinical diagnosis of pelvic inflammatory disease (PID) and those without. However, a statistically significant association between high levels of OmcB-specific antibody and a PID diagnosis (P< 0.05) was observed. Using antibody levels as an indirect measure of antigen expression, our results suggest that gender- and/or site-specific (cervix in females vs. urethra in males) stimuli may control pmp expression in infected patients. They also support the possible existence of immune biomarkers of chlamydial infection associated with disease and underline the need for high resolution screening in human serum.

IntroductionReproductive and sexual health (RSH) are core components of comprehensive care, yet often omitted in addiction treatment. We characterize knowledge of and interest in RSH services and contraceptive method awareness and use in a rural, Appalachian outpatient clinic.Materials and methodsBetween September 2016 and April 2018, a convenience sample of 225 patients receiving treatment for opioid use disorder at an outpatient buprenorphine/naloxone clinic was collected. Participants completed a cross-sectional RSH survey that included demographics, interest in RSH service integration, contraceptive use, and contraceptive knowledge.ResultsA total of 212 people (126 non-pregnant women, 29 pregnant women, and 57 men) completed the survey of whom 45.8% indicated interest in adding RSH services. Services of interest include regular physical exams (44.8%), STI/STD testing (41.0%), and contraception education and administration (38.2%). There were no significant differences between interest in co-located services between women and men (P = 0.327). Current contraceptive use was low (17.9-30.9%) among women and men. Contraceptive method awareness was 43.3% for high efficacy methods and 50.0% for medium efficacy methods. Women and currently pregnant women knew more total, high, and medium efficacy contraceptive method than men (P = 0.029).DiscussionBoth women and men in this sample are interested in co-located RSH services. Current contraceptive use was low among participants. Contraceptive knowledge was lower among men compared to women, and generally low. Providing co-located RSH services may facilitate RSH education, contraceptive method uptake, and promote engagement across various RSH domains.

OBJECTIVES: Fentanyl has come to dominate the U.S. illicit opioid supply. We aimed to characterize and examine correlates of preferences for fentanyl vs. other opioids among individuals starting OUD treatment. METHODS: We interviewed 250 adults initiating buprenorphine treatment with positive fentanyl toxicology at intake. We characterized opioid preferences and examined bivariate associations between opioid preference (preference for heroin, fentanyl, heroin-fentanyl mix, or other opioid) and sociodemographic characteristics, psychosocial factors, and substance use behaviors. We then used multinomial logistic regression to examine factors independently associated with fentanyl preferences. RESULTS: Over half (52.0 %) of participants preferred fentanyl (21.2 % fentanyl alone, 30.8 % heroin-fentanyl mix). In bivariate comparisons, participants who preferred fentanyl were a higher acuity group with respect to risks and problems in general. In the multinomial logistic regression, people who preferred fentanyl, either alone or mixed with heroin, used non-prescribed buprenorphine less in the 30 days preceding treatment entry compared to people who preferred heroin or other opioids (RRRalone= 0.88 [0.78, 0.99]; P = 0.037 and RRRmixed= 0.91 [0.84, 0.99]; P = 0.046). People who preferred fentanyl alone were also younger (RRR= 0.93 [0.90, 0.97]; P < 0.001) and more likely to have severe mental illness (RRR= 2.5 [1.1, 5.6]; P = 0.027) than people who prefer heroin or other opioids. CONCLUSIONS: Many people with OUD report preferring fentanyl. People who express preference for fentanyl differ substantively from those with other opioid preferences, and may be at elevated risk for poor health outcomes. Understanding preferences surrounding fentanyl could inform treatment and harm reduction interventions.

We examined how breastfeeding advice in the context of cannabis use differed by race and ethnicity. Data from the 2017-2018 PRAMS (Pregnancy Risk Assessment Monitoring System) survey were used to assess differences in breastfeeding guidance related to cannabis use among 1,213 individuals who self-reported cannabis use 3 months before or during pregnancy. A multivariable logistic regression model was specified to examine the extent to which the odds of receiving prenatal advice against breastfeeding if using cannabis differed by self-reported race and ethnicity. We found that non-Hispanic Black people were four times more likely than non-Hispanic White people to be advised against breastfeeding if using cannabis (adjusted odds ratio 4.1, 95% CI 2.1-8.2). Pregnant non-Hispanic Black people were disproportionately advised not to breastfeed if using cannabis.

The prevalence of pregnant people with opioid use disorder (OUD), including those receiving medications for opioid use disorder (MOUD), is increasing. Challenges associated with pain management in people with OUD include tolerance, opioid-induced hyperalgesia, and risk for return to use. Yet, there are few evidence-based recommendations for pain management in the setting of pregnancy and the postpartum period, and many peripartum pain management studies exclude people with OUD. This scoping review summarized the available literature on peridelivery pain management in people with OUD, methodologies used, and identified specific areas of knowledge gaps. PubMed and Embase were comprehensively searched for publications in all languages on peripartum pain management among people with OUD, both treated with MOUD and untreated. Potential articles were screened by title, abstract, and full text. Data abstracted were descriptively analyzed to map available evidence and identify areas of limited or no evidence. A total of 994 publications were imported for screening on title, abstracts, and full text, yielding 84 publications identified for full review: 32 (38.1%) review articles, 14 (16.7%) retrospective studies, and 8 (9.5%) case reports. There were 5 randomized controlled trials. Most studies (64%) were published in perinatology (32; 38.1%) journals or anesthesiology (22; 26.2%) journals. Specific areas lacking trial or systematic review evidence include: (1) methods to optimize psychological and psychosocial comorbidities relevant to acute pain management around delivery; (2) alternative nonopioid and nonpharmacologic analgesia methods; (3) whether or not to use opioids for severe breakthrough pain and how best to prescribe and monitor its use after discharge; (4) monitoring for respiratory depression and sedation with coadministration of other analgesics; (5) optimal neuraxial analgesia dosing and adjuncts; and (6) benefits of abdominal wall blocks after cesarean deliver

BackgroundKnowledge of medical conditions and their evidence-based medications varies among individuals. This range of knowledge may affect attitudes and influence medical decision-making of both patients and providers. Perceptions may be even more impactful in pregnancy, a timeframe subject to bias, and in diseases that include behavioral symptoms and often carry significant societal stigma, such as opioid use disorder (OUD). We present our findings from a survey assessing participants' knowledge of three distinct medical conditions (diabetes mellitus, bipolar disorder, and OUD) and how this knowledge affects perceptions of these disease states during pregnancy.MethodsUsing existing surveys in the literature as a guideline, we designed a cross-sectional survey including multiple-choice questions to evaluate our hypothesis that less knowledge about a medical condition would result in more negative opinions towards that condition and its treatment throughout pregnancy. Participants responded to perception statements using a 5-point Likert scale (1 = "strongly disagree," 5 = "strongly agree"). Surveys were administered to patients in prenatal care, patients in OUD treatment, medical students, and medical residents within a single institution. Response means were generated and compared using t tests and ANOVA.ResultsA total of 323 participants completed the survey. There were differences in knowledge between respondent groups and by disease state, with prenatal patients having the least knowledge of all groups about OUD diagnosis (88.5% of prenatal patients answered correctly) and its treatment (91.8% answered correctly). Overall Likert means of all responses demonstrated that participants agreed that new mothers with OUD (mean 4.27, 5 = "strongly agree") and their babies (4.12) would have challenges that others would not, compared to mothers with bipolar disorder (4.03) and their babies (3.60) as well as mothers with diabetes (3.87) and their babies (3.47), p < .00

Methadone regulations have changed minimally since 1974, despite advances in the understanding of the nature of opioid use disorder (OUD) and the role of medications in its treatment. At that time, most patients with OUD were considered to have anti-social personality disorders and the regulations aimed to exert maximal control over medication access. Six- or seven-day clinic attendance is required for months, regardless of distance, or childcare and other social responsibilities. Take home medications are not allowed unless rigid and formulaic conditions are met. Although addiction medicine has rejected the "criminal" paradigm in favor of OUD as a treatable medical disorder, methadone regulations have not kept pace with the science. Pregnancy is characterized by an ultra-rapid metabolic state, but regulations prevent the use of daily divided doses of methadone to maintain stability. This results in repeated episodes of maternal/fetal opioid withdrawal, as well as other fetal physiologic abnormalities. Interference with dose regimen adjustments prevents optimal outcomes. Further, methadone clinics are mostly urban, leaving patients in rural areas without access. This led to excessive morbidity and mortality when the opioid crisis hit. The response of merely expanding capacity in overcrowded urban clinics created a contagion menace when Covid-19 arrived. Pregnant women (and parents with children) were forced to negotiate dosing in dangerous conditions. A revised methadone system must provide treatment that is local, flexible, and limited in size to manage viral contagion risks. This regulatory change can most easily be started by changing regulations that adversely affect pregnant women.

BackgroundThe postpartum year is a vulnerable period for women with opioid use disorder, with increased rates of fatal and nonfatal overdose; however, data on the continuation of medications for opioid use disorder on a population level are limited.ObjectiveThis study aimed to examine the effect of discontinuing methadone and buprenorphine in women with opioid use disorder in the year following delivery and determine the extent to which maternal and infant characteristics are associated with time to discontinuation of medications for opioid use disorder.Study designThis population-based retrospective cohort study used linked administrative data of 211,096 deliveries in Massachusetts between 2011 and 2014 to examine the adherence to medications for opioid use disorder. Individuals receiving medications for opioid use disorder after delivery were included in the study. Here, demographic, psychosocial, prenatal, and delivery characteristics are described. Kaplan-Meier survival analysis and Cox regression modeling were used to examine factors associated with medication discontinuation.ResultsA total of 2314 women who received medications for opioid use disorder at delivery were included in our study. Overall, 1484 women (64.1%) continued receiving medications for opioid use disorder for a full 12 months following delivery. The rate of continued medication use varied from 34% if women started on medications for opioid use disorder the month before delivery to 80% if the medications were used throughout pregnancy. Kaplan-Meier survival curves differed by maternal race and ethnicity (the 12-month continuation probability was .65 for White non-Hispanic women and .51 for non-White women; P<.001) and duration of use of prenatal medications for opioid use disorder (12-month continuation probability was .78 for women with full prenatal engagement and .60 and .44 for those receiving medications for opioid use disorder ≥5 months [but not throughout pregnancy] and ≤4 months pre

BackgroundRecovery is a multidimensional process that includes health, quality of life, and citizenship. Recovery capital is a strengths-based concept representing the sum of an individual's resources that support recovery. This study (1) describes recovery capital, (2) examines the relationship between recovery capital and treatment duration, and (3) assesses differences by gender in recovery capital among people receiving medication for opioid use disorder (MOUD).MethodsThis is a secondary data analysis of a cross-sectional study, with survey and medical record review components, conducted with patients recruited from an office-based opioid treatment clinic between July and September 2019. Analyses included participants receiving MOUD with buprenorphine who completed the Brief Assessment of Recovery Capital (BARC-10; n = 130). Univariate analyses explored differences by gender. Multivariate linear regression assessed the relationship between BARC-10 total score and length of current treatment episode.ResultsParticipants were 54.6% women and 67.4% Black with mean age of 42.4 years (SD = 12.3). Mean length of current MOUD treatment was 396.1 days (SD = 245.9). Total BARC-10 scores were high, but participants perceived low community-level resources. Women scored higher than men within the health and purpose recovery dimensions. While length of treatment was not associated with BARC-10 score, experiencing recent discrimination was associated with a significantly lower BARC-10 score.ConclusionsRecovery capital among individuals receiving MOUD was high suggesting that participants have resources to support recovery, but gender differences and prevalent discrimination highlight areas for improved intervention. More work is needed to investigate recovery capital as an alternative treatment outcome to abstinence in outpatient MOUD populations.

Background and aimsOpioid-related overdose is increasingly linked to pregnancy-associated deaths, but factors associated with postpartum overdose are unknown. We aimed to estimate the strength of the association between maternal and infant characteristics and postpartum opioid-related overdose.DesignRetrospective cohort study using a linked, population-level data set.SettingMassachusetts, United States.ConclusionAmong women who delivered live infants in Massachusetts, USA between 2012 and 2014, maternal diagnosis of OUD, prior non-fatal overdose, infant diagnosis of NAS and high unscheduled health-care utilization appeared to be positively associated with postpartum opioid overdose. However, more than half of postpartum overdoses in that period were to women without a diagnosis of OUD. Engagement in methadone or buprenorphine treatment in the month prior to delivery was not sufficient to reduce the odds of postpartum overdose.ParticipantsWomen who delivered one or more live births from 2012 to 2014 (n = 174 517).MeasurementsThe primary outcome was opioid-related overdose in the postpartum year. We used multivariable logistic regression to explore the independent associations of maternal (demographics, substance use, pregnancy) and infant [gestational age, birthweight, neonatal abstinence syndrome (NAS)] characteristics with postpartum opioid overdose. Findings were stratified by maternal opioid use disorder (OUD) diagnosis.FindingsThere were 189 deliveries to women who experienced ≥ 1 opioid overdose in the first year postpartum (11 of 10 000 deliveries). Among women with postpartum opioid overdose, 46.6% had an OUD diagnosis within 12 months before delivery. In our adjusted model, maternal diagnosis of OUD [adjusted odds ratio (aOR) = 3.61, 95% confidence interval (CI) = 1.73-7.51] and prior non-fatal overdose (aOR = 2.40, 95% CI = 1.11-5.17) were most strongly associated with postpartum overdose. After st

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.

The opioid crisis has had a substantial effect on women who are pregnant and parenting, focusing both public health and policymaker attention on opioids and on other substance use in pregnancy and postpartum. There is overwhelming consensus on the principle of a non-punitive approach towards substance use in pregnancy. Experts universally endorse supportive policies, which reduce barriers to care, and oppose punitive policies, which can increase the fear of legal penalties, discouraging women from seeking prenatal care and addiction treatment during pregnancy. We review the change over time in state-level policy environments around substance use in pregnancy and contrast the policy response with the principles and guidance from professional societies and federal agencies. Between 2000 and 2015, more states adopted punitive policies than supportive policies, in direct contrast with guidance from professional societies and federal agencies. The increase in punitive policies over the past two decades suggests that the gap between principles and practice is widening. Furthermore, the increase in punitive policies is occurring in the context of significant structural barriers to comprehensive health care across the woman's entire life course, a growing awareness of racial and ethnic inequities in maternal morbidity and mortality, and increasing restrictions at the state level on abortion access. Women with substance use disorder (SUD) need comprehensive, coordinated, evidence-based, trauma-informed, family-centered care. This care should be delivered in a compassionate and non-punitive environment, and clinicians, policymakers, and public health officials all have a role to play in achieving this goal.

Background and aimsThe established standard care in pregnancy is medication for opioid use disorder (MOUD); however, many institutions of incarceration do not have MOUD available. We aimed to describe the number of incarcerated pregnant women with opioid use disorder (OUD) in the United States and jails' and prisons' MOUD in pregnancy policies.DesignEpidemiological surveillance study of 6 months of outcomes of pregnant, incarcerated women with OUD and cross-sectional survey of institutional policies.SettingUnited States.ParticipantsTwenty-two state prison systems and six county jails.MeasurementsThe number of pregnant women with OUD admitted and treated with methadone, buprenorphine or withdrawal; policies on provision of MOUD and withdrawal in pregnancy.FindingsTwenty-six per cent of pregnant women admitted to prisons and 14% to jails had OUD. One-third were managed through withdrawal. The majority who were prescribed MOUD were on methadone (78%, prisons; 81%, jails), not buprenorphine. While most sites (n = 18 prisons, n = four jails) continued pre-incarceration MOUD in pregnancy, very few initiated in custody (n = four prisons; n = two jails). Two-thirds of prisons and three-quarters of jails providing MOUD in pregnancy discontinued it postpartum.ConclusionsIn this sample of US prisons and jails, one-third required pregnant women with opioid use disorder to go through withdrawal, contrary to medical guidelines. More women were prescribed methadone than buprenorphine, despite the fewer regulatory barriers on prescribing buprenorphine. Most sites stopped medication for opioid use disorder postpartum, signaling prioritization of the fetus, not the mother. Pregnant incarcerated women with opioid use disorder in the United States frequently appear to be denied essential medications and receive substandard medical care.

ObjectiveTo describe obstetrician-gynecologists' practices and attitudes related to opioid use among pregnant and postpartum women.Study designA 2017 cross-sectional survey assessed U.S. obstetrician-gynecologists' (N = 462; response rate = 34%) practices (management) and attitudes (knowledge, preparedness, confidence, barriers, and resources needed) related to opioid use among pregnant and postpartum women. Modified Poisson regression determined adjusted prevalence ratios (aPR) for advising medication-assisted therapy (MAT) for pregnant women with opioid use disorder (OUD) by knowledge, confidence, and preparedness.ResultsOf respondents, 33% always or usually advised MAT to pregnant women with OUD. Confidence in treating pregnant women who use opioids (aPR: 1.3, 95% CI: 1.0-1.8) and knowledge that substance use services were covered under the Affordable Care Act (aPR: 1.4, 95% CI: 1.1-1.8) were associated with advising MAT.ConclusionEvidence suggests that efforts are needed to enhance physician confidence to manage pregnant and postpartum patients who use opioids, which may increase optimal care of this patient population.

We characterized the composition and structure of the vaginal microbiota in a cohort of 149 women with genital Chlamydia trachomatis infection at baseline who were followed quarterly for 9 months after antibiotic treatment. At time of diagnosis, the vaginal microbiota was dominated by Lactobacillus iners or a diverse array of bacterial vaginosis-associated bacteria including Gardnerella vaginalis. Interestingly, L. iners-dominated communities were most common after azithromycin treatment (1 g monodose), consistent with the observed relative resistance of L. iners to azithromycin. Lactobacillus iners-dominated communities have been associated with increased risk of C. trachomatis infection, suggesting that the impact of antibiotic treatment on the vaginal microbiota could favor reinfections. These results provide support for the dual need to account for the potential perturbing effect(s) of antibiotic treatment on the vaginal microbiota, and to develop strategies to protect and restore optimal vaginal microbiota.

BackgroundNeedle syringe programs (NSPs), a proven harm reduction strategy for people who inject drugs, frequently offer limited healthcare services for their clients. Women who inject drugs face multiple barriers to accessing reproductive health care in traditional settings: personal histories of trauma, judgmental treatment from providers, and competing demands on their time. Our aim was to implement patient-centered reproductive healthcare services at a Seattle NSP.MethodsWe interviewed clients and staff of an NSP in Seattle and staff of other community-based organizations serving women who inject drugs, then used the Consolidated Framework for Implementation Research to code transcripts deductively. Based on our qualitative work, we implemented reproductive health care at the NSP program 1 day per week. We evaluated the implementation by surveying staff and clients and auditing charts over a 9-month period.ResultsClients and staff (N = 15 for clients, N = 13 for staff) noted a high unmet need for trauma-informed, accessible reproductive health care. We successfully implemented reproductive health care services including short- and long-acting contraception, sexually transmitted disease testing, and cervical cancer screening. Survey data was limited but demonstrated client satisfaction with services.ConclusionsIntegrating reproductive health care into an NSP's clinical services is feasible and can be a source of low-barrier preventive care for women unable to seek gynecologic care elsewhere.

Opioid use disorder (OUD) in pregnant women has increased significantly in recent years. Maintaining these women on sublingual (SL) buprenorphine (BUP) is an evidence-based practice but BUP-SL is associated with several disadvantages that an extended-release (XR) BUP formulation could eliminate. The National Drug Abuse Treatment Clinical Trials Network (CTN) is conducting an intent-to-treat, two-arm, open-label, pragmatic randomized controlled trial, Medication treatment for Opioid-dependent expectant Mothers (MOMs), to compare mother and infant outcomes of pregnant women with OUD treated with BUP-XR, relative to BUP-SL. A second aim is to determine the relative economic value of utilizing BUP-XR. Approximately 300 pregnant women with an estimated gestational age (EGA) of 6-30 weeks, recruited from 12 sites, will be randomized in a 1:1 ratio to BUP-XR or BUP-SL, balancing on site, EGA, and BUP-SL status (taking/not taking) at the time of randomization. Participants will be provided with study medication and attend weekly medication visits through 12 months postpartum. Participants will be invited to participate in two sub-studies to evaluate the: 1) mechanisms by which BUP-XR may improve mother and infant outcomes; and 2) effects of prenatal exposure to BUP-XR versus BUP-SL on infant neurodevelopment. This paper describes the key design decisions for the main trial made during protocol development. This Investigational New Drug (IND) trial uniquely uses pragmatic features where feasible in order to maximize external validity, hence increasing the potential to inform clinical practice guidelines and address multiple knowledge gaps for treatment of this patient population.

ObjectiveTo describe obstetrician-gynecologists' practices and attitudes related to substance use screening in pregnant patients.Study designA 2017 cross-sectional survey assessed US obstetrician-gynecologists' (n = 462; response rate = 34%) practices (substance use screening frequency and methods) and attitudes (practice priority of screening, confidence in treating, and responsibility statements). Chi-squared tests and adjusted modified Poisson regression were used to estimate associations between practices and attitudes.ResultsOf 353 respondents with screening information, 79% frequently screen for substance use and 11% used a validated instrument. Confidence was the highest for treating pregnant patients using tobacco (81%). Respondents whose practices make it a high priority to screen for all substances were 1.2 times as likely to frequently screen as their counterparts (95% CI: 1.1-1.3).ConclusionsFour out of five obstetricians-gynecologists reported a high frequency of substance use screening in pregnant patients. Findings highlight the importance of increasing priority of substance use screening by obstetrician-gynecologists.

The mechanism(s) by which Lactobacillus-dominated cervicovaginal microbiota provide a barrier to Chlamydia trachomatis infection remain(s) unknown. Here we evaluate the impact of different Lactobacillus spp. identified via culture-independent metataxonomic analysis of C. trachomatis-infected women on C. trachomatis infection in a three-dimensional (3D) cervical epithelium model. Lactobacillus spp. that specifically produce d(-) lactic acid were associated with long-term protection against C. trachomatis infection, consistent with reduced protection associated with Lactobacillus iners, which does not produce this isoform, and with decreased epithelial cell proliferation, consistent with the observed prolonged protective effect. Transcriptomic analysis revealed that epigenetic modifications involving histone deacetylase-controlled pathways are integral to the cross talk between host and microbiota. These results highlight a fundamental mechanism whereby the cervicovaginal microbiota modulates host functions to protect against C. trachomatis infection.IMPORTANCE The vaginal microbiota is believed to protect women against Chlamydia trachomatis, the etiologic agent of the most prevalent sexually transmitted infection (STI) in developed countries. The mechanism underlying this protection has remained elusive. Here, we reveal the comprehensive strategy by which the cervicovaginal microbiota modulates host functions to protect against chlamydial infection, thereby providing a novel conceptual mechanistic understanding. Major implications of this work are that (i) the impact of the vaginal microbiota on the epithelium should be considered in future studies of chlamydial infection and other STIs and (ii) a fundamental understanding of the cervicovaginal microbiota's role in protection against STIs may enable the development of novel microbiome-based therapeutic strategies to protect women from infection and improve vaginal and cervical health.

ObjectiveTo estimate whether methadone, buprenorphine, or detoxification treatment is the most cost-effective approach to the management of opioid use disorder (OUD) during pregnancy.MethodsWe created a decision analytic model that compared the cost effectiveness (eg, the marginal cost of the strategy in U.S. dollars divided by the marginal effectiveness of the strategy, measured in quality-adjusted life-years [QALYs]) of initiation of methadone, buprenorphine, or detoxification in treatment of OUD during pregnancy. Probabilities, costs, and utilities were estimated from the existing literature. Incremental cost-effective ratios for each strategy were calculated, and a ratio of $100,000 per QALY was used to define cost effectiveness. One-way sensitivity analyses and a Monte Carlo probabilistic sensitivity analysis were performed.ResultsUnder base assumptions, initiation of buprenorphine was more effective at a lower cost than either methadone or detoxification and thus was the dominant strategy. Buprenorphine was no longer cost effective if the cost of methadone was 8% less than the base-case estimate ($1,646/month) or if the overall costs of detoxification were 121% less than the base-case estimate for the detoxification cost multiplier, which was used to increase the values of both inpatient and outpatient management of detoxification by a factor of 2. Monte Carlo analyses revealed that buprenorphine was the cost-effective strategy in 70.5% of the simulations. Direct comparison of buprenorphine with methadone demonstrated that buprenorphine was below the incremental cost-effective ratio in 95.1% of simulations; direct comparison between buprenorphine and detoxification demonstrated that buprenorphine was below the incremental cost-effective ratio in 45% of simulations.ConclusionUnder most circumstances, we estimate that buprenorphine is the cost-effective strategy when compared with either methadone or detoxification as treatment for OUD during pregnancy.

Individuals with opioid use disorder (OUD) often relapse when exposed to opioid-related cues. Previous functional magnetic resonance imaging (fMRI) studies have identified neuronal corticolimbic changes related to drug cue reactivity in OUD. However, the corresponding manner in which brain regions interact is still unclear. Effective (directional) connectivity was analyzed using dynamic causal modeling of fMRI data acquired from 27 OUD participants (13 with OUD and 14 with OUD and cocaine use disorder [OUD+CUD]), while performing an opioid-word Stroop task. Participants were shown opioid and neutral words presented in different colors and were instructed to indicate word color but ignore word meaning. The effects of opioid words relative to neutral words on effective connectivity and on behavioral reaction time were defined as modulatory change and attentional bias, respectively. For all the 27 participants, left anterior cingulate cortex (ACC) to right hippocampus effective connectivity exhibited the largest modulatory change, which was positively correlated with attentional bias. The findings for the ACC to hippocampus EC were consistent across OUD and CUD found in a previous study.

The developmental impact of opioid use during pregnancy is a subject of ongoing debate. Short-term neonatal outcomes, such as lower birth weight and neonatal abstinence syndrome, are the most well-recognized outcomes. However, knowledge gaps exist regarding longer-term neurocognitive and mental health outcomes. In this article, we summarize an expert panel discussion that was held in April 2018 by the Substance Abuse and Mental Health Services Administration and attended by national experts in the field of perinatal opioid exposure and its impact on child development. Despite the challenges with research in this area, there is emerging literature revealing an association between neonates exposed to opioids in utero and longer-term adverse neurocognitive, behavioral, and developmental outcomes. Although adverse sequalae may not be apparent in the neonatal period, they may become more salient as children develop and reach preschool and school age. Multiple variables (genetic, environmental, and biological) result in a highly complex picture. The next steps and strategies to support families impacted by opioid use disorder are explored. Model programs are also considered, including integrated care for the child and mother, parenting supports, and augmentations to home visiting.

IntroductionChlamydia trachomatis (CT) is a common sexually transmitted pathogen with significant reproductive health implications. Data are mounting that the bacterial communities that reside within the vagina, collectively termed the vaginal microbiota, aid in defense against sexually transmitted infections. Disruptions in the vaginal microbiota, such as during episodes of bacterial vaginosis, may increase susceptibility to infection. Herein, we describe the clinical core protocol for a NIH NIAID Cooperative Research Center titled Eco-Pathogenomic of Chlamydial Reproductive Tract Infection. The primary goals of the project are to describe the interrelationships between the urogenital microenvironment, the properties of the pathogen and immunologic responses of the host in men and women, and their association with clinical outcomes of CT infection in women.MethodsMen and women with confirmed genital CT infections were recruited to a number of study protocols, including cross-sectional and longitudinal sub-studies. Participants completed a demographic and sexual health questionnaire and underwent a physical exam at baseline. In the longitudinal study arms, biologic samples were collected daily, weekly, and monthly to determine the relationships between the vaginal microbiota, prevalent CT infection, re-infection and treatment.DiscussionThe biological samples and the demographic and history information collected throughout this study will be used for various analyses evaluating genomics, metabolomics and host immune responses in the context of CT infection.

Brianna Lindsay1, Jennifer Albrecht1, Mishka Terplan1,21Department of Epidemiology and Public Health, University of Maryland, 2Department of Obstetrics, Gynecology, and Reproductive Science, University of Maryland School of Medicine, Baltimore, MD, USAAbstract: Pregnant methamphetamine users who leave substance use treatment against professional advice may be at risk of poorer health outcomes. To examine the hypothesis that methamphetamine use during pregnancy may be associated with leaving substance use treatment against professional advice, the 2006 Treatment Episode Data Set was analyzed. A logistic regression adjusting for age, race, service setting, prior substance abuse treatment, criminal justice referral, and education was conducted. Inclusion criteria were met by 18,688 pregnant admissions; 26.4% identified methamphetamines as their primary substance of use. Frequency of use was identified as an effect modifier, therefore results were stratified by less than weekly use and weekly or more use. Methamphetamine use was significantly associated with leaving treatment against professional advice regardless of usage level. However, the odds of leaving treatment were greater among women using methamphetamine less than weekly. Further investigation into this association may be warranted due to the complications that may result from methamphetamine use during pregnancy.Keywords: pregnancy, methamphetamines, treatment, attrition
