Methadone and buprenorphine discontinuation among postpartum women with opioid use disorder

Racial and ethnic disparities in reproductive medicine in the United States: a narrative review of contemporary high-quality evidence

There has been increasing debate around how or if race and ethnicity should be used in medical research-including the conceptualization of race as a biological entity, a social construct, or a proxy for racism. The objectives of this narrative review are to identify and synthesize reported racial and ethnic inequalities in obstetrics and gynecology (ob/gyn) and develop informed recommendations for racial and ethnic inequity research in ob/gyn. A reproducible search of the 8 highest impact ob/gyn journals was conducted. Articles published between January 1, 2010 and June 30, 2023 containing keywords related to racial and ethnic disparities, bias, prejudice, inequalities, and inequities were included (n=318). Data were abstracted and summarized into 4 themes: 1) access to care, 2) adherence to national guidelines, 3) clinical outcomes, and 4) clinical trial diversity. Research related to each theme was organized topically under the headings i) obstetrics, ii) reproductive medicine, iii) gynecologic cancer, and iv) other. Additionally, interactive tables were developed. These include data on study timeline, population, location, and results for every article. The tables enable readers to filter by journal, publication year, race and ethnicity, and topic. Numerous studies identified adverse reproductive outcomes among racial and ethnic minorities as compared to white patients, which persist despite adjusting for differential access to care, socioeconomic or lifestyle factors, and clinical characteristics. These include higher maternal morbidity and mortality among Black and Hispanic/Latinx patients; reduced success during fertility treatments for Black, Hispanic/Latinx, and Asian patients; and lower survival rates and lower likelihood of receiving guideline concordant care for gynecological cancers for non-White patients. We conclude that many racial and ethnic inequities in ob/gyn cannot be fully attributed to patient characteristics or access to care. Research focused on explaining these disparities based on biological differences incorrectly reinforces the notion of race as a biological trait. More research that deconstructs race and assesses efficacy of interventions to reduce these disparities is needed.

Beyond a simple cause and effect relationship: Exploring the long-term outcomes of children prenatally exposed to opioids and other substances

The long-term outcomes of children exposed to opioids and other substances in utero, specifically those diagnosed with Neonatal Abstinence Syndrome (NAS), present a complex interaction of different factors. First, NAS and its clinical presentation will be defined, then summarized will be an overview of NAS prevalence, recent trends, and significance of NAS in the context of the rising synthetic opioid and polysubstance use. Highlighted will also be the identified risk factors for NAS, especially regarding the role of environmental and psychosocial stressors during pregnancy. Finally, reviewed will be the existing NAS literature, including its gaps and limitations, and suggested recommendations for future research and policy considerations for improving care for children and families impacted by NAS.

Addressing stigma for families affected by opioid use disorder

Pregnant and parenting people with opioid use disorder commonly experience stigma, or the enactment of negative attitudes, beliefs, and stereotypes, during their pregnancy and at delivery. We will describe four different domains of stigma: self, interpersonal, structural, and policy, and discuss how they intersect to amplify the experiences of shame, anxiety, isolation, lack of trust for birthing people and parents that can contribute to the avoidance of prenatal care and substance use treatment which can impact pregnancy and infant health outcomes. We will review a case example where stigma contributed to poor care, review preferred person-first language to use when talking to and about families impacted by opioid use disorder, and describe emerging interventions to address and mitigate the effects of stigma in the perinatal setting.

Rates of buprenorphine prescribing and racial disparities among patients with opioid overdose

Background

Awareness of the relationship between real-world buprenorphine prescribing and overdose frequency is limited, especially in the Southeastern United States. We described buprenorphine prescribing rates for patients experiencing nonfatal opioid overdoses in the context of overdose frequency.

Methods

Electronic medical records review was conducted at an urban, academic hospital in Alabama from January 1 through December 31, 2021. Patients with opioid use disorder (OUD) and nonfatal opioid overdoses, dispositioned from either the emergency department (ED), inpatient, or outpatient affiliated clinics, were identified by International Classification of Diseases-10 codes.

Results

The study included 358 unique patients. Many patients were white (71.5 %), male (59.2 %), and uninsured (54.2 %), with a mean age of 42.0±12.8 years. The majority (85.5 %) experienced one to three overdoses, and 14.5 % of patients had more than three overdoses. The buprenorphine prescription rate increased to 55.8 % when patients had more than three overdoses, compared to one overdose (34.5 %) and two to three overdoses (37.4 %) (p=0.025). Compared to females, more males overdosed more than once (p=0.004). Black patients were less likely to receive buprenorphine prescriptions than white patients (27.3 % vs. 44.5 %, p=0.004). Compared to patients with multiple overdoses, more patients with one overdose had public insurance (p=0.028) and were less likely to present to the ED (p<0.001).

Conclusion

Under-prescribing of buprenorphine is high among patients with OUD and opioid overdoses, even in patients with multiple overdoses, and there appear to be racial disparities in prescribing. Our findings indicate clinical opportunities for improving buprenorphine prescribing and reducing the current disparities.

Challenges for Antepartum Care of the Individual with Perinatal Substance Use: An Empirical Integrative Review of Novel Approaches to Improve Care

INTRODUCTION

Perinatal substance use continues to rise across the United States presenting unique challenges to providing antepartum care. Polysubstance use, limited and late engagement in health care, co-occurring mood disorders, and several social barriers are well documented. This review seeks to summarize these barriers and present novel approaches to caring for this high-risk population.

METHODS

Inclusion criteria for this study focused on peer-reviewed articles that explicitly detailed a direct impact on the provision or receipt of antenatal care in the setting of substance use within the United States that were published in the last 5 years. PubMed and Web of Science were used to find applicable articles. Of the 156 articles found, 10 relevant articles were selected for the final empirical integrative review that entailed data evaluation using the Mixed Methods Appraisal Tool (MMAT) and thematic analysis.

RESULTS

10 review articles met inclusion; 3 were qualitative, 6 were quantitative and nonrandomized, and one was quantitative descriptive. Six articles met MMAT quality criteria, and there were significant limitations in every article. Topics included opioid use disorder (n = 6), general substance use (n = 3), and tobacco use (n = 1). Themes included integrated models of prenatal care, colocated care, resource coordination, and peer support along with the role of the perinatal health care professional and consistent use of a substance use screening tool.

DISCUSSION

A comprehensive and multidisciplinary care model is necessary to meet the complex and urgent needs of individuals with perinatal substance use that not only meets recommendations for opioid maintenance therapy or substance use cessation but the important areas of accessibility and interpersonal support. Future research should focus on the development, implementation, and evaluation of new models of care for this vulnerable population.

Factors associated with medications for opioid use disorder (MOUD) treatment success during the pregnancy and postpartum periods: A scoping review

BACKGROUND

Medications for opioid use disorder (MOUD) are a crucial intervention for pregnant and postpartum individuals with opioid use disorder (OUD). However, there is paucity of data on the factors associated with MOUD treatment success in this population. This scoping review aimed to evaluate factors associated with MOUD success during the pregnancy and postpartum period.

METHODS

We completed a structured search of MEDLINE, CINAHL, PsycINFO, Web of Science, and ProQuest databases. Eligible studies included a metric of success in outpatient treatment in the pregnancy and postpartum period and were conducted in the United States after the Food and Drug Administration's approval of buprenorphine in 2002. Reviewers independently screened studies for inclusion and extracted data. The primary outcome was treatment success (i.e., treatment adherence, abstinence from illicit opioids, or retention in care) during pregnancy and up to 12 months postpartum.

RESULTS

Data from 15 studies were included. Medications included methadone, naltrexone and buprenorphine (mono or combination therapy). High daily dose of buprenorphine as mono or combination therapy, early initiation and longer duration of MOUD were associated with treatment success. Legal involvement, homelessness, and rural residency were negatively associated with treatment success. There were no differences in outcomes of individuals receiving telemedicine versus in-person care.

CONCLUSION

We identified several factors associated with MOUD treatment success among individuals with OUD during the pregnancy and postpartum periods. These factors may help guide future research and inform the development and adaptation of interventions tailored to better meet the needs of this key population.

Risk factors of overdose in maternal patients with opioid use disorder: a scoping review

Background: Opioid-related overdoses significantly contribute to mortality in pregnancy and the postpartum period. Few studies report risk factors predisposing pregnant and postpartum patients with opioid use disorder (OUD) to overdose.Objective: This scoping review aims to describe the risk factors predisposing pregnant and postpartum patients with OUD to overdose.Method: Included studies identified pregnant and/or postpartum patients with OUD and differentiated between those who experienced overdose and those who did not. Of the 1060 articles, 8 met the criteria, examining 90,860 pregnant and postpartum patients with OUD.Results: Consistent use of medications for OUD (MOUD) during pregnancy and the postpartum period was the most frequently identified factor reducing overdose risk. Critical times of heightened overdose risk include the first trimester and the 7-12-month postpartum period. Pregnancy complications, such as stillbirth, severe maternal morbidity, preterm birth, and cesarean delivery, also increase risk. Opioid overdose is associated with being houseless, incarcerated, young, unmarried, publicly insured, not graduating high school, co-occurring substance use disorders, and inadequate prenatal care. Legislative changes, such as not classifying OUD in pregnancy as "child abuse" and increasing Medicaid reimbursement for Screening, Brief Intervention, and Referral to Treatment programs, are crucial to reducing risk. The impact of race and the influence of co-occurring psychiatric disorders was inconsistently reported.Conclusion: This scoping review identifies significant risk factors for opioid overdose in pregnant and postpartum patients. Improving access through enhanced Medicaid reimbursement, non-punitive reporting policies, and non-stigmatized care are keys to reducing overdose.

Services for perinatal patients with opioid use disorder: a comprehensive Baltimore City-wide 2023 assessment

BACKGROUND

Overdose is a leading cause of maternal mortality; in response, maternal mortality review committees have recommended expanding substance use disorder (SUD) screening, improving collaboration between obstetric and SUD treatment providers, and reducing fragmentation in systems of care. We undertook an analysis of the perinatal SUD treatment landscape in Baltimore, Maryland in order to identify barriers to treatment engagement during pregnancy and the postpartum period and guide system improvement efforts.

METHODS

We conducted a survey of seven birthing hospitals, 31 prenatal care practices, and 108 SUD treatment providers in Baltimore from April-June 2023. Organizations were asked to quantify care for perinatal patients with opioid use disorder (OUD) as well as about screening, service availability, referral practices, and support needed to improve care.

RESULTS

61% of the 145 contacted organizations responded. Birthing hospitals reported caring for pregnant persons with OUD with greater frequency than prenatal care practices or SUD treatment programs. Most birthing hospitals and prenatal care practices reported screening for OUD at intake, but the minority reported using validated tools. Service availability varied by type of organization and type of service. In general, prenatal care practices offered the fewest number of SUD-related services. Most SUD treatment programs that offered buprenorphine or methadone to the general population also offered these medications to pregnant patients. Withdrawal management for comorbid alcohol/benzodiazepine use disorders during pregnancy was more limited. The majority of birthing hospitals and prenatal care practices reported offering neither direct naloxone distribution nor prescriptions. Few SUD treatment programs offered tailored services for perinatal patients or for parents of young children, and many programs do not permit children onsite. Respondents reported high levels of interest in education and consultative support on SUD treatment in pregnancy within obstetric settings and on pregnancy-related medical concerns within SUD programs.

CONCLUSIONS

This project provides a comprehensive picture of services available for treatment of perinatal OUD in a major US city. Results have served as a guide for ongoing citywide system improvement efforts by our project team and offer a model for other jurisdictions hoping to strengthen services for perinatal OUD and reduce maternal mortality.

Perinatal Naloxone Care Practices: Survey Results From Persons With OUD and Providers

OBJECTIVE

Little is known about naloxone care practices for peripartum persons from the patient or provider perspectives. The objective of this study was to survey peripartum persons and providers about naloxone-related practices.

METHODS

Individuals who had an OUD diagnosis during a pregnancy and Ohio healthcare professionals who provide care for peripartum patients with OUD and/or infants with prenatal exposure to opioids were eligible for this study. Patient experiences were assessed through a survey codeveloped with members with lived experience of opioid use disorder. Provider perspectives were examined through a survey codeveloped by the Ohio Perinatal Quality Collaborative. Descriptive statistics and logistic regression were used to examine the proportion of participants who received or provided naloxone care practices and the effect on having a naloxone kit during the perinatal period.

RESULTS

Of the 100 peripartum participants with opioid use disorder, 24% reported receiving naloxone from their prenatal care provider and 48% reported ever having a naloxone kit during the perinatal period. Of the 63 maternal care provider participants, 32 (49%) reported discussing or prescribing naloxone to pregnant patients. Of the 62 pediatric provider participants, 10 (16%) reported that they provide naloxone information to parenting individuals of their patients.

CONCLUSION

Study results demonstrate critical gaps in naloxone care practices for peripartum persons, emphasizing the need for targeted interventions at the patient, clinician, practice, and system levels.

Strategies to improve delivery of equitable and evidence-informed care for pregnant and birthing people with a substance use disorder in acute care settings: A scoping review protocol

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.

Treatment setting and buprenorphine discontinuation: an analysis of multi-state insurance claims

BACKGROUND

Potential differences in buprenorphine treatment outcomes across various treatment settings are poorly characterized in multi-state administrative data. We thus evaluated the association of opioid use disorder (OUD) treatment setting and insurance type with risk of buprenorphine discontinuation among commercial insurance and Medicaid enrollees initiated on buprenorphine.

METHODS

In this observational, retrospective cohort study using the Merative MarketScan databases (2006-2016), we analyzed buprenorphine retention in 58,200 US adults with OUD. Predictor variables included insurance status (Medicaid vs commercial) and treatment setting, operationalized as substance use disorder (SUD) specialty treatment facility versus outpatient primary care physicians (PCPs) versus outpatient psychiatry, ascertained by linking physician visit codes to buprenorphine prescriptions. Treatment setting was inferred based on timing of prescriber visit claims preceding prescription fills. We estimated time to buprenorphine discontinuation using multivariable cox regression.

RESULTS

Among enrollees with OUD receiving buprenorphine, 26,168 (45.0%) had prescriptions from SUD facilities without outpatient buprenorphine treatment, with the remaining treated by outpatient PCPs (n = 23,899, 41.1%) and psychiatrists (n = 8133, 13.9%). Overall, 50.6% and 73.3% discontinued treatment at 180 and 365 days respectively. Buprenorphine discontinuation was higher among enrollees receiving prescriptions from SUD facilities (aHR = 1.03[1.01-1.06]) and PCPs (aHR = 1.07[1.05-1.10]). Medicaid enrollees had lower buprenorphine retention than those with commercial insurance, particularly those receiving buprenorphine from SUD facilities and PCPs (aHR = 1.24[1.20-1.29] and aHR = 1.39[1.34-1.45] respectively, relative to comparator group of commercial insurance enrollees receiving buprenorphine from outpatient psychiatry).

CONCLUSION

Buprenorphine discontinuation is high across outpatient PCP, psychiatry, and SUD treatment facility settings, with potentially lower treatment retention among Medicaid enrollees receiving care from SUD facilities and PCPs.

Postpartum Treatment for Chronic Hepatitis C Virus Among People With Opioid Use Disorder: A Prospective Pilot Clinical Trial

OBJECTIVE

The objective of this study was to evaluate the feasibility and acceptability of postpartum hepatitis C virus (HCV) treatment integrated within a substance use treatment program for pregnant and postpartum people with opioid use disorder (OUD).

METHODS

We conducted a prospective pilot clinical trial of sofosbuvir/velpatasvir (SOF/VEL) treatment among postpartum people with OUD and HCV. Feasibility outcomes included rates of HCV treatment utilization and completion, medication adherence, and sustained virologic response 12 weeks after treatment completion (SVR12). Acceptability was measured through self-reported adverse effects and medication adherence.

RESULTS

From January 2018 to August 2021, 164 pregnant people received care for OUD at the study site. Among those, 64 (39.0%) were HCV antibody positive and 45 (27.4%) had active HCV infection. Among 45 eligible patients, 32 (71.1%) enrolled and 21 (46.7%) initiated HCV treatment. Of 21 participants who initiated treatment, 16 (76.2%) completed the SOF/VEL treatment, and 11 (52.4%) completed the SVR12. All participants who completed treatment were cured. Common reasons for dropout during the HCV clinical care cascade were OUD treatment discontinuation, illicit substance use recurrence, and lost to follow-up. Participants reported high satisfaction with HCV treatment, including minimal adverse effects, and no HCV treatment concerns.

CONCLUSIONS

Nearly half of pregnant people with HCV initiated postpartum treatment within an integrated care model of HCV treatment within a substance use treatment program. Postpartum SOF/VEL was efficacious, tolerable, and acceptable. Despite this, postpartum HCV treatment among people with OUD remains challenging, and many barriers remain.

Receipt and duration of buprenorphine treatment during pregnancy and postpartum periods in a national privately-insured cohort

Background

Research gaps exist on the use of medications for opioid use disorder (OUD) among birthing people.

Methods

This retrospective cohort study included people who underwent childbirth deliveries during 2017-2020 and had a diagnosis of OUD identified from a national private insurance claims database. Buprenorphine prescriptions received during the year before childbirth and the year after childbirth were obtained from pharmacy claims. Logistic regressions were used to estimate associations between receipt of buprenorphine and individual and state-level factors.

Results

Among a sample of 1,523 birthing people diagnosed with OUD, 540 (35.5 %) received buprenorphine during the pregnancy or postpartum periods. About half (51.5 %) of new recipients of buprenorphine received treatment for at least six months and, of those, one-third experienced a treatment interruption. The buprenorphine receipt rate differed significantly by race and ethnicity: 28.8 % of non-Hispanic Black birthing people with OUD and 22.8 % of Hispanic birthing people with OUD received buprenorphine treatment in contrast to 37.7 % of non-Hispanic white birthing people (aOR 0.53 [95 % CI 0.35-0.81] and 0.59 [95 % CI 0.37-0.96], respectively). The buprenorphine use rate increased over time from 29.7 % in 2017 to 42.9 % in 2020. Birthing people living in states with punitive policies related to substance use in pregnancy had the lowest buprenorphine use rate of 22.7 % as compared to 43.0 % in states with least restrictive policies.

Conclusion

In this national sample of privately-insured individuals, by 2020, 42.9 % of birthing people with OUD received buprenorphine treatment. Treatment discontinuation and interruptions were common in the period surrounding childbirth.

Postpartum medication for opioid use disorder outcomes associated with prenatal treatment and neighborhood-level social determinants

BACKGROUND

Opioid use disorder is a leading cause of death through the year postpartum.

OBJECTIVE

This study aimed to identify the association of neighborhood-level social determinants of health and prenatal opioid use disorder treatment receipt with the outcomes of medication treatment for opioid use disorder through the year postpartum among a cohort of birthing people.

STUDY DESIGN

This was a population-based retrospective cohort study that used state Medicaid claims and enrollment data for the 1690 individuals who delivered a live infant between July 1, 2016 and December 31, 2020 and received medication for opioid use disorder at delivery. The primary exposure was the state Health Opportunity Index, a composite measure of social determinants of health linked at the census-tract level. Secondary exposures included comprehensiveness of opioid use disorder treatment and duration of medication treatment for opioid use disorder received prenatally. Outcomes included the duration and continuity of postpartum medication treatment for opioid use disorder, operationalized as the time from delivery to the discontinuation of medication treatment for opioid use disorder, and percentage of days covered by medication treatment for opioid use disorder within the 12 months after delivery, respectively.

RESULTS

Within the study sample, 711 deliveries were to birthing people in the lowest state Health Opportunity Index tercile (indicating high burden of negative social determinants of health), 647 in the middle state Health Opportunity Index tercile, and 332 in the highest state Health Opportunity Index tercile. Using stepwise multivariable regression (Cox proportional hazards and negative binomial models) guided by a socioecological framework, prenatal receipt of more comprehensive opioid use disorder treatment and/or longer duration of prenatal medication treatment for opioid use disorder was associated with improved 1-year postpartum opioid use disorder treatment outcomes (duration and continuity of medication treatment for opioid use disorder). When the state Health Opportunity Index was added to the models, these significant associations remained stable, with the state Health Opportunity Index not demonstrating an association with the outcomes (duration hazard ratio, 1.39; 95% confidence interval, 0.551-3.512; continuity relative risk, 1.024; 95% confidence interval, 0.323-3.247).

CONCLUSION

Targeted efforts at expanding access to and quality of evidence-based opioid use disorder treatments for reproductive-age people across the life course should be prioritized within the spectrum of work aimed at eradicating disparities in pregnancy-related mortality.

Access to Services for Pregnant People With Opioid Use Disorder in Jails in the United States

The aim of this study was to assess the availability of medications for opioid use disorder (MOUD) and other services for pregnant people in jails in counties heavily impacted by opioid overdose in the United States. Counties were selected based on absolute number and population rate of opioid-overdose fatalities. Structured interviews were completed with representatives from 174 jails that house pregnant women. Descriptive statistics examine MOUD availability and differences in service provision and community-level characteristics based on MOUD availability. Most jails in the study sample (84.5%) had MOUD available for pregnant people; however, less than half of these jails ensured continuity of care. Jails without MOUD available are more likely to provide non-MOUD substance use services. These jails are more often located in smaller, rural counties in the Midwest and have higher rates of White residents and lower rates of Hispanic and African American residents. Gaps in MOUD availability in jails and continuity of care violate medical guidelines for treatment of pregnant patients with opioid use disorder and increase their risk of overdose. In addition, there are disparities across communities in access to MOUD for pregnant people in jails.

Interventions to Support Engagement in Addiction Care Postpartum: Principles and Pitfalls

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.

Opioid Use Disorder and Overdose in the First Year Postpartum: A Rapid Scoping Review and Implications for Future Research

OBJECTIVE

Opioid overdose is a leading cause of maternal mortality, yet limited attention has been given to the consequences of opioid use disorder (OUD) in the year following delivery when most drug-related deaths occur. This article provides an overview of the literature on OUD and overdose in the first year postpartum and provides recommendations to advance maternal opioid research.

APPROACH

A rapid scoping review of peer-reviewed research (2010-2021) on OUD and overdose in the year following delivery was conducted in PubMed, PsycINFO, and Web of Science databases. This article discusses existing research, remaining knowledge gaps, and methodological considerations needed.

RESULTS

Seven studies were included. Medication for OUD (MOUD) was the only identified factor associated with a reduction in overdose rates. Key literature gaps include the role of mental health disorders and co-occurring substance use, as well as interpersonal, social, and environmental contexts that may contribute to postpartum opioid problems and overdose.

CONCLUSION

There remains a limited understanding of why women in the first year postpartum are particularly vulnerable to opioid overdose. Recommendations include: (1) identifying subgroups of women with OUD at highest risk for postpartum overdose, (2) assessing opioid use, overdose, and risks throughout the first year postpartum, (3) evaluating the effect of co-occurring physical and mental health conditions and substance use disorders, (4) investigating the social and contextual determinants of opioid use and overdose after delivery, (5) increasing MOUD retention and treatment engagement postpartum, and (6) utilizing rigorous and multidisciplinary research methods to understand and prevent postpartum overdose.

Opportunities to expand postpartum support for those in recovery from opioid use disorder: Results from a qualitative study

Introduction

Over the past two decades the national prevalence of opioid use disorder (OUD) during pregnancy has increased more than 600%. Managing recovery from OUD during the postpartum period can be particularly challenging. Thus, we sought to identify ways to expand perinatal OUD treatment to ultimately reduce risk of postpartum return to opioid misuse.

Methods

We conducted in-depth semi-structured interviews with pregnant or postpartum (i.e., gave birth within the past year) mothers who have OUD, as well as with professionals who work with this population. Interviews were audio-recorded, transcribed, and coded for themes using Dedoose software using an eco-social framework.

Results

Participants included 7 mothers (median age 32 years old; 100% receiving treatment for OUD) and 11 professionals (average of 12.5 years in the field; n=7 healthcare providers, n=4 child safety caseworkers). A total of 10 major themes emerged in three levels. First, at an individual level themes included mental health, personal responsibility, and individual agency. Second, at the inter-individual level themes included support from friends and family, and other sources of support. Next, at the systems/institutional level themes included culture of healthcare systems, an ill-equipped healthcare system, social determinates of health, and continuum of care. Finally, a theme identified across all three levels included keeping mother and baby together.

Conclusions

Several opportunities to enhance the support and clinical care of OUD during the perinatal period were identified. Additional work is needed to explore how these themes may be incorporated into existing programs and/or the development of new interventions.

Assessment of COVID-19-Driven Changes in an Integrated OBGYN-Addiction Treatment Clinic and Future Implications

OBJECTIVE

The COVID-19 pandemic prompted healthcare delivery changes, but the associated impacts on substance use disorder treatment outcomes among pregnant and parenting people are unknown. This study aims to (1) describe COVID-19-driven clinical practice changes, (2) evaluate clinic-level visit attendance patterns, and (3) compare patient-level treatment engagement outcomes across 3 COVID-19 pandemic phases in an OBGYN-addiction treatment clinic.

METHODS

COVID-19 phases include pre-COVID-19 (August 2019-February 2020), early COVID-19 (March-December 2020), and COVID-19 vaccine (January-July 2021). OBGYN-addiction treatment clinical practice changes were summarized. Clinic-level attended medical provider visits were analyzed. Patient-level treatment engagement outcomes (buprenorphine continuation, visit attendance, and virtual visits) were assessed in a cohort of pregnant and parenting people enrolled in a clinic research registry. Mixed-level logistic regression models determined the relationship between the COVID-19 phases and the patient-level outcomes.

RESULTS

The study site made several COVID-19-driven clinical practice changes, including implementing a hybrid virtual/in-person system for medical visits. Clinic-level medical provider appointments increased between the first and second COVID-19 phases and remained high in the third phase. Among participants included in patient-level outcome analyses (N = 27), there were no differences in the early COVID-19 phase compared with the pre-COVID-19 phase in buprenorphine continuation, any visits, or medical visits. There was a decrease in all patient-level outcomes in the COVID-19 vaccine phase compared with pre-COVID-19 ( P < 0.05). Virtual visits increased between the first 2 phases and remained high during the third.

CONCLUSION

Within our OBGYN-addiction treatment clinic, implementation of tailored, patient-centered treatment strategies supported clinic- and patient-level treatment engagement throughout the pandemic.

Biopsychosocial contexts of timely and adequate prenatal care utilization among women with criminal legal involvement and opioid use disorder

OBJECTIVE

Pregnant women with criminal legal involvement and opioid use disorder (CL-OUD) living in non-urban regions may be at risk for complex biomedical, psychological, and social barriers to prenatal care and healthy pregnancy. Yet, limited research has explored prenatal care utilization patterns among this subpopulation. This study describes the biopsychosocial factors of pregnant women with a history of criminal legal involvement and opioid use disorder (CL-OUD) associated with timely prenatal care initiation and adequate prenatal care utilization (APNCU).

METHODS

Analyses were conducted on a subsample of medical record data from an observational comparative effectiveness study of medication treatment models for pregnant women with diagnosed opioid use disorder (OUD) who received prenatal care in Northern New England between 2015 and 2022. The subsample included women aged ≥ 16 years with documented criminal legal involvement. Analyses included χ2, Fisher exact tests, and multiple logistic regression to assess differences in timely prenatal care and APNCU associated with biopsychosocial factors selected by backwards stepwise regression.

RESULTS

Among 317 women with CL-OUD, 203 (64.0%) received timely prenatal care and 174 (54.9%) received adequate care. Timely prenatal care was associated with having two or three prior pregnancies (aOR 2.37, 95% CI 1.07-5.20), receiving buprenorphine at care initiation (aOR 1.85, 95% CI 1.01-3.41), having stable housing (aOR 2.49, 95% CI 1.41-4.41), and being mandated to court diversion (aOR 4.06, 95% CI 1.54-10.7) or community supervision (aOR 2.05, 95% CI 1.16-3.63). APNCU was associated with having a pregnancy-related medical condition (aOR 2.17, 95% CI 1.27-3.71), receiving MOUD throughout the entire prenatal care period (aOR 3.40, 95% CI 1.45-7.94), having a higher number of psychiatric diagnoses (aOR 1.35, 95% CI 1.07-1.70), attending a rurally-located prenatal care practice (aOR 2.14, 95% CI 1.22-3.76), having stable housing (aOR 1.94, 95% CI 1.06-3.54), and being mandated to court diversion (aOR 3.11, 95% CI 1.19-8.15).

CONCLUSION

While not causal, results suggest that timely and adequate prenatal care among women with CL-OUD may be supported by OUD treatment, comorbid indications for care, stable access to social resources, and maintained residence in the community (i.e., community-based alternatives to incarceration).

Prospective acceptability of digital phenotyping among pregnant and parenting people with opioid use disorder: A multisite qualitative study

Background

While medications for opioid use disorder (MOUD) effectively treat OUD during pregnancy and the postpartum period, poor treatment retention is common. Digital phenotyping, or passive sensing data captured from personal mobile devices, namely smartphones, provides an opportunity to understand behaviors, psychological states, and social influences contributing to perinatal MOUD non-retention. Given this novel area of investigation, we conducted a qualitative study to determine the acceptability of digital phenotyping among pregnant and parenting people with opioid use disorder (PPP-OUD).

Methods

This study was guided by the Theoretical Framework of Acceptability (TFA). Within a clinical trial testing a behavioral health intervention for PPP-OUD, we used purposeful criterion sampling to recruit 11 participants who delivered a child in the past 12  months and received OUD treatment during pregnancy or the postpartum period. Data were collected through phone interviews using a structured interview guide based on four TFA constructs (affective attitude, burden, ethicality, self-efficacy). We used framework analysis to code, chart, and identify key patterns within the data.

Results

Participants generally expressed positive attitudes about digital phenotyping and high self-efficacy and low anticipated burden to participate in studies that collect smartphone-based passive sensing data. Nonetheless, concerns were noted related to data privacy/security and sharing location information. Differences in participant assessments of burden were related to length of time required and level of remuneration to participate in a study. Interviewees voiced broad support for participating in a digital phenotyping study with known/trusted individuals but expressed concerns about third-party data sharing and government monitoring.

Conclusion

Digital phenotyping methods were acceptable to PPP-OUD. Enhancements in acceptability include allowing participants to maintain control over which data are shared, limiting frequency of research contacts, aligning compensation with participant burden, and outlining data privacy/security protections on study materials.

Initiation and Treatment Discontinuation of Medications for Opioid Use Disorder in Pregnant People Compared With Nonpregnant People

OBJECTIVE

To examine the association between pregnancy and medications for opioid use disorder (MOUD) initiation and discontinuation among reproductive-aged people receiving treatment for opioid use disorder (OUD) in the United States.

METHODS

We conducted a retrospective cohort study of people with gender recorded as female, aged 18-45 years, in the Merative TM MarketScan ® Commercial and Multi-State Medicaid Databases (2006-2016). Opioid use disorder and pregnancy status were identified based on inpatient or outpatient claims for established International Classification of Diseases, Ninth and Tenth Revision diagnosis and procedure codes. The main outcomes were buprenorphine and methadone initiation and discontinuation, determined by using pharmacy and outpatient procedure claims. Analyses were conducted at the treatment episode level. Adjusting for insurance status, age, and co-occurring psychiatric and substance use disorders, we used logistic regression to estimate MOUD initiation and used Cox regression to estimate MOUD discontinuation.

RESULTS

Our sample included 101,772 reproductive-aged people with OUD, encompassing 155,771 treatment episodes (mean age 30.8 years, 64.4% Medicaid insurance, 84.1% White), of whom 2,687 (3.2%, encompassing 3,325 episodes) were pregnant. In the pregnant group, 51.2% of treatment episodes (1,703/3,325) involved psychosocial treatment without MOUD, in comparison with 61.1% (93,156/152,446) in the nonpregnant comparator group. In adjusted analyses assessing likelihood of initiation for individual MOUD, pregnancy status was associated with an increase in buprenorphine (adjusted odds ratio [aOR] 1.57, 95% CI 1.44-1.70) and methadone initiation (aOR 2.04, 95% CI 1.82-2.27). Discontinuation rates of MOUD at 270 days were high for both buprenorphine (72.4% for nonpregnant episodes vs 59.9% for pregnant episodes) and methadone (65.7% for nonpregnant episodes vs 54.1% for pregnant episodes). Pregnancy was associated with a decreased likelihood of discontinuation at 270 days for both buprenorphine (adjusted hazard ratio [aHR] 0.71, 95% CI 0.67-0.76) and methadone (aHR 0.68, 95% CI 0.61-0.75), in comparison with nonpregnant status.

CONCLUSION

Although a minority of reproductive-aged people with OUD in the United States are initiated on MOUD, pregnancy is associated with a significant increase in treatment initiation and a reduced risk of medication discontinuation.

Postpartum Opioid-Related Mortality in Patients With Public Insurance

OBJECTIVE

To assess the incidence and risk factors for postpartum opioid overdose death and describe other causes of postpartum death in individuals with opioid use disorder (OUD).

METHODS

We conducted a cohort study that used health care utilization data from the Medicaid Analytic eXtract linked to the National Death Index in the United States from 2006 to 2013. All pregnant individuals with live births or stillbirths and continuous enrollment for 3 months before delivery were eligible, including 4,972,061 deliveries. A subcohort of individuals with a documented history of OUD in the 3 months before delivery was identified. We estimated the cumulative incidence of death as occurring between delivery and 1 year postpartum among all individuals and individuals with OUD. Risk factors for opioid overdose death were assessed using odds ratios (ORs) and descriptive statistics, including demographics, health care utilization, obstetric conditions, comorbidities, and medications.

RESULTS

The incidence of postpartum opioid overdose death per 100,000 deliveries was 5.4 (95% CI 4.5-6.4) among all individuals and 118 (95% CI 84-163) among individuals with OUD. Individuals with OUD had a sixfold higher incidence of all-cause postpartum death than all individuals. Common causes of death in individuals with OUD were other drug- and alcohol-related deaths (47/100,000), suicide (26/100,000), and other injuries, including accidents and falls (33/100,000). Risk factors strongly associated with postpartum opioid overdose death included mental health and other substance use disorders. Among patients with OUD, postpartum use of medication to treat OUD was associated with 60% lower odds of opioid overdose death (OR 0.4, 95% CI 0.1-0.9).

CONCLUSION

Postpartum individuals with OUD have a high incidence of postpartum opioid overdose death and other preventable deaths, including nonopioid substance-related injuries, accidents, and suicide. Use of medications for OUD is strongly associated with lower opioid-related mortality.

Annual Research Review: Prenatal opioid exposure - a two-generation approach to conceptualizing neurodevelopmental outcomes

Opioid use during pregnancy impacts the health and well-being of two generations: the pregnant person and the child. The factors that increase risk for opioid use in the adult, as well as those that perpetuate risk for the caregiver and child, oftentimes replicate across generations and may be more likely to affect child neurodevelopment than the opioid exposure itself. In this article, we review the prenatal opioid exposure literature with the perspective that this is not a singular event but an intergenerational cascade of events. We highlight several mechanisms of transmission across generations: biological factors, including genetics and epigenetics and the gut-brain axis; parent-child mechanisms, such as prepregnancy experience of child maltreatment, quality of parenting, infant behaviors, neonatal opioid withdrawal diagnosis, and broader environmental contributors including poverty, violence exposure, stigma, and Child Protective Services involvement. We conclude by describing ways in which intergenerational transmission can be disrupted by early intervention.

An Integrated Care Model for Pregnant and Postpartum Individuals Receiving Medication for Opioid Use Disorder

OBJECTIVES

Perinatal opioid use disorder is increasing. Integrated obstetric/addiction care models likely optimize parent-infant dyad outcomes, but the ideal combination of services is unknown. This study (1) describes pregnancy-to-postpartum service utilization by people receiving buprenorphine at an integrated Obstetric/Addiction Clinic and (2) explores the association between service utilization and postpartum buprenorphine continuation.

METHODS

This retrospective medical record review study uses research registry data from an outpatient Obstetric/Addiction Clinic. All patients are invited to participate in the research registry. For patients who consent, monthly medical record abstractions are conducted beginning with their first clinic visit to collect demographic, obstetric, and substance use disorder treatment variables. Present analyses included patients who delivered an infant between June 2019 and June 2021, started buprenorphine during pregnancy, and were receiving buprenorphine at delivery. Overall service utilization was the number of services (range 0-12) used between 28-weeks gestation and 12-weeks postpartum. Bivariate analyses and multivariable logistic regression assessed associations between service utilization and buprenorphine continuation.

RESULTS

Participants (n = 42) were primarily non-Latinx White (67%) with comorbid psychiatric diagnoses (95%). On average, participants used 6 services; prenatal care, mental health care, and postpartum contraception were most utilized. Overall, 69% of participants continued buprenorphine at 6 months postpartum. This did not differ by level of service utilization (bivariate [ P = 0.07], multivariable [ P = 0.16]).

CONCLUSION

Integrated care with a harm reduction focus supports pregnancy-to-postpartum service utilization and buprenorphine continuation in a patient sample at high risk for medication for opioid use disorder discontinuation. Further work is needed to identify evidence-based methods to individualize integrated obstetric/addiction care.

Project BETTER: A Family-Centered, Technology-Delivered Intervention for Pregnant People with Opioid Use Disorder

Birthing people with opioid use disorder (OUD) face unique stressors during the transition from pregnancy to postpartum that can negatively impact the maternal-infant dyad. This study aimed to describe the development of a family-centered, technology-delivered intervention tailored to help pregnant people receiving medication for OUD (MOUD) prepare for this transition. Formative data from patients and providers identified intervention content: (1) recovery-oriented strategies for the pregnancy-to-postpartum transition; (2) guidance around caring for an infant with opioid withdrawal symptoms; and (3) preparation for child welfare interactions. The content was reviewed in successive rounds by an expert panel and modified. Pregnant and postpartum people receiving MOUD pre-tested the intervention modules and provided feedback in semi-structured interviews. The multidisciplinary expert panel members (n = 15) identified strengths and areas for improvement. Primary areas for improvement included adding content, providing more structure to help participants navigate the intervention more easily, and revising language. Pre-testing participants (n = 9) highlighted four themes: reactions to intervention content, navigability of the intervention, feasibility of the intervention, and recommendation of the intervention. All iterative feedback was incorporated into the final intervention modules for the prospective randomized clinical trial. Family-centered interventions tailored for pregnant people receiving MOUD should be informed by patient-reported needs and multidisciplinary perspectives.

Disparities in opioid use disorder-related hospital use among postpartum Virginia Medicaid members

INTRODUCTION

The overdose crisis is increasingly revealing disparities in opioid use disorder (OUD) outcomes by race and ethnicity. Virginia, like other states, has witnessed drastic increases in overdose deaths. However, research has not described how the overdose crisis has impacted pregnant and postpartum Virginians. We report the prevalence of OUD-related hospital use during the first year postpartum among Virginia Medicaid members in the years preceding the COVID-19 pandemic. We secondarily assess how prenatal OUD treatment is associated with postpartum OUD-related hospital use.

METHODS

This population-level retrospective cohort study used Virginia Medicaid claims data for live infant deliveries between July 2016 and June 2019. The primary outcome of OUD-related hospital use included overdose events, emergency department visits, and acute inpatient stays. Independent variables of interest were prenatal receipt of medication for OUD (MOUD) and receipt of non-MOUD treatment components in line with a comprehensive care approach (e.g., case management, behavioral health). Both descriptive and multivariate analyses were performed for all deliveries and stratified by White and Black non-Hispanic individuals to bring attention to the devastating impacts of the overdose crisis within communities of color.

RESULTS

The study sample included 96,649 deliveries. Over a third were by Black birthing individuals (n = 34,283). Prenatally, 2.5 % had evidence of OUD, which occurred more often among White (4 %) than Black (0.8 %) non-Hispanic birthing individuals. Postpartum OUD-related hospital use occurred in 10.7 % of deliveries with OUD, more commonly after deliveries by Black, non-Hispanic birthing individuals with OUD (16.5 %) than their White, non-Hispanic counterparts (9.7 %), and this disparity persisted in the multivariable analysis (Black AOR 1.64, 95 % CI 1.14-2.36). Postpartum OUD-related hospital events were less frequent for individuals receiving versus not receiving postpartum MOUD within 30 days prior to the event. Prenatal OUD treatment, including MOUD, was not associated with decreased odds of postpartum OUD-related hospital use in the race-stratified models.

CONCLUSION

Postpartum individuals with OUD are at high risk for mortality and morbidity, especially Black individuals not receiving MOUD after delivery. An urgent need remains to effectively address the systemic and structural drivers of racial disparities in transitions of OUD care through the one-year postpartum period.

Pain Management After Cesarean Delivery Among Women with Opioid Use Disorder: Results from a Retrospective Pregnancy Cohort in a Rural Region of the Midwest

Background

Increasing numbers of pregnant women are being treated with buprenorphine for opioid use disorder (OUD), which can interfere with effectiveness of other opioids used for pain relief, making perioperative guidance for patients requiring cesarean delivery unclear.

Methods

Using a retrospective cohort design, we abstracted 8 years of medical records (2013-2020) from a hospital in rural Michigan. We compared analgesic use (as a proxy for pain) and hospital length of stay (LOS) between groups of women with OUD whose buprenorphine treatment was (1) discontinued before cesarean delivery (discontinuation) versus (2) continued throughout the perioperative period (maintenance). We used t-tests and Fisher's Exact tests for comparison of continuous and categorical variables, respectively.

Results

Maternal characteristics reflected the local population (87% non-Hispanic White; 9% American Indian). Of 12,179 mothers giving birth during the study timeframe, 87 met all inclusion criteria (2.4% with diagnosed OUD; 38% of those delivered by cesarean; 76% of those received prenatal buprenorphine treatment). Using the first 2 days of the hospital stay as the standard time window for comparison, there were no differences in perioperative opioid analgesic use (mean ± standard deviation [SD] = 141.6 ± 205.4 vs. 134.0 ± 136.3 morphine milligram equivalents, p = 0.89) or LOS (mean ± SD = 2.9 ± 0.9 vs. 3.3 ± 1.0 days, p = 0.14) between discontinuation (n = 17) versus maintenance (n = 70). There was a lower use of acetaminophen in the discontinuation group (mean ± SD = 3,842.6 ± 2,108.1 vs. 4,938.2 ± 2,008.4 mg, p = 0.0489).

Conclusion

This study provides empirical evidence supporting continued buprenorphine treatment for women with OUD throughout the perioperative period of a cesarean delivery in a rural setting, although replication with larger sample sizes would provide more confidence in the results.

An integrative literature review of substance use treatment service need and provision to pregnant and postpartum populations in carceral settings

Pregnancy is a critical time to provide access to substance use treatment; this is especially true among incarcerated populations, who are known to be at particularly high risk of poor health outcomes. In this integrated literature review, we (1) report what is known about the prevalence of substance use among incarcerated pregnant and postpartum populations; (2) describe substance use treatment programs and current care practices of pregnant and postpartum populations in carceral settings; and (3) explore recommendations and strategies for increasing access to substance use treatment for incarcerated pregnant and postpartum populations. A comprehensive search of seven electronic databases yielded in the retrieval of 139 articles that were assessed for inclusion. Of the retrieved articles, 33 articles met criteria for inclusion in this review. A review of the literature revealed that the understanding of substance use prevalence among pregnant incarcerated women is limited. We also found that treatment of substance use disorders among pregnant and postpartum populations is not routinely available, enhanced perinatal services are sorely needed, and substance use treatment programs are feasible with the help of community partnerships. More research is required to understand current substance use treatment initiatives and outcomes for pregnant women in prison. In addition, strategies for integrating evidence-based, substance use treatment in carceral settings is also needed. Future directions are discussed.

Incarceration status at buprenorphine initiation and OUD treatment outcomes during pregnancy

Introduction

Opioid use disorder (OUD) is a leading cause of pregnancy-associated deaths. OUD treatment with buprenorphine (BUP) reduces overdose risk and improves perinatal outcomes. Incarceration can be a barrier to receipt of OUD treatment during pregnancy and postpartum. The objective of this study was to examine differences in BUP continuation at delivery by patients' incarceration status at the time of BUP initiation.

Methods

This is a secondary analysis of a retrospective cohort study of pregnant patients with OUD who delivered at an academic medical center and initiated BUP between January 1, 2018, and March 30, 2020. The primary outcome was BUP continuation at delivery, abstracted from the state prescription monitoring program and electronic medical record, along with incarceration status. Bivariate analysis was used to assess the relationship between BUP continuation and incarceration status.

Results

Our sample included 76 patients, with 62% of patients incarcerated at BUP initiation (n = 47). Among the entire sample, 90.7% (n = 68) received BUP at delivery. Among patients who were incarcerated at BUP initiation, 97% remained on BUP at delivery; among patients who were not incarcerated at BUP initiation, 79% remained on BUP at delivery (p = 0.02).

Conclusion

In our sample from a health system housing a care model for pregnant and parenting people with OUD with local jail outreach, BUP continuation rates at delivery were high, both for patients who were and were not incarcerated at BUP initiation. Findings are intended to inform future work to develop and evaluate evidence-based, patient-centered interventions to expand OUD treatment access for incarcerated communities.

Psychiatric comorbidities and their treatment predict buprenorphine continuation among postpartum people with opioid use disorder

Background

Opioid use disorder (OUD) is a growing crisis among pregnant and postpartum people. Psychiatric comorbidities are common, yet how they impact OUD treatment outcomes is not well characterized. The aim of this study was to assess the association of psychiatric comorbidities and receipt of psychiatric treatment with buprenorphine continuation through one year postpartum among a sample of people with OUD.

Methods

A subsample was identified from a larger retrospective cohort of patients receiving buprenorphine for OUD at the time of delivery from an academic medical center between 2017 and 2020. Medical record abstractions were conducted during pregnancy through one year postpartum. Independent variables included any psychiatric diagnosis and postpartum receipt of psychiatric treatment (medication or behavioral health). The primary outcome was week of buprenorphine discontinuation. Cox Proportional Hazard models were used.

Results

Of 138 patients, 71.8% had a psychiatric condition and 35.5% continued buprenorphine for a full year postpartum. Postpartum buprenorphine continuation was associated with (a) Psychiatric co-morbidity (buprenorphine discontinuation HR 0.49; 95% CI 0.29, 0.82), (b) Receipt of psychiatric medications in weeks 39-52 postpartum (buprenorphine discontinuation HR 0.21; 95% CI 0.06, 0.83), and (c) Receipt of behavioral health therapy in weeks 9-38 postpartum (buprenorphine discontinuation HR 0.40; 95% CI 0.18, 0.90).

Conclusion

Our work suggests a dynamic relationship between OUD treatment outcomes, psychiatric comorbidities and receipt of psychiatric treatments through the highly vulnerable postpartum period. Clinicians and researchers alike should work to advance patient-centered engagement in integrated care models tailored for this unique population.

Project BETTER: Preliminary Feasibility and Acceptability of a Technology-Delivered Educational Program for Pregnant and Postpartum People with Opioid Use Disorder

Background

Postpartum people with opioid use disorder (OUD) report feeling underprepared for the pregnancy to postpartum transition. We developed a novel, technology-delivered educational intervention for pregnant and parenting people with OUD to address this gap. This study provides a theoretically grounded assessment of the feasibility and acceptability of a new technology-delivered educational intervention (Project BETTER) for pregnant and parenting people receiving medication for OUD (MOUD).

Materials and Methods

Pregnant and postpartum people receiving MOUD were recruited from a perinatal addiction clinic research registry to pilot test the technology-delivered intervention. Participants completed one of three modules (Postpartum Transition, Neonatal Opioid Withdrawal Syndrome, or Child Welfare Interactions) and a survey assessing acceptability based on the theoretical framework of acceptability (TFA). We measured feasibility using process, resource, management, and scientific assessments. Demographics were self-reported. Clinical characteristics were abstracted from the medical record.

Results

Feasibility was promising, with 17 of 28 participants approached (61%) agreeing to participate; 70% of these participants (N = 12; 58% White and 23% Black, all with public insurance) completed an intervention module and the study assessments, and all reported understanding how the modules worked. Acceptability was strong, with median ratings of 4 or 5 on a 5-point scale for all positively scored TFA domains. Compared to learning from a provider, participants also reported feeling more comfortable and less stigmatized learning from the intervention.

Conclusion

Our theoretically grounded assessment suggests high feasibility and acceptability for Project BETTER, and provides justification for further evaluation in a clinical trial setting. Technology-delivered educational interventions may help reduce stigma and enhance prenatal education.

Pregnant and Postpartum Individuals' Knowledge, Attitudes, and Perceptions of Extended-release Buprenorphine for Treatment of Opioid Use Disorder

OBJECTIVE

The objective of this study is to explore pregnant and postpartum individuals' knowledge, attitudes, and perceptions regarding extended-release buprenorphine (XR-BUP) treatment for opioid use disorder.

METHODS

We conducted a paper-based survey of pregnant or postpartum individuals with opioid use disorder attending a multidisciplinary perinatal addiction specialty care clinic where XR-BUP is available. Participants' nonidentifiable demographic and treatment characteristics were collected, including duration and satisfaction of current medication for opioid use disorder. Participants' knowledge, attitudes, and perceptions about XR-BUP were assessed using a 5-point Likert scale. Descriptive statistics were used to summarize the data.

RESULTS

From February 2021 to August 2021, 79 of 98 eligible participants completed the survey (81% response rate). More than 9 of 10 participants were currently taking medication for opioid use disorder, and 7 individuals (8.9%) were taking XR-BUP. Nearly half (49.4%) had never heard of XR-BUP, and 84.8% did not personally know anyone taking XR-BUP. However, 45.6% and 29.1% would consider an injectable medication for opioid use disorder to avoid trouble remembering to take their daily medications and avoid opioid withdrawal symptoms, respectfully.

CONCLUSIONS

In a population of pregnant and postpartum individuals, nearly half were unaware of a monthly XR-BUP option for the treatment of opioid use disorder. Many were interested in considering this medication. Future studies are needed to rigorously assess outcomes associated with XR-BUP among pregnant and postpartum individuals with opioid use disorder.

Prescribing Characteristics Associated With Opioid Overdose Following Buprenorphine Taper

IMPORTANCE

Retention in buprenorphine therapy is associated with a lower risk of opioid overdose. Nevertheless, many patients discontinue treatment, and there is limited evidence to guide buprenorphine tapering.

OBJECTIVE

To understand what prescribing characteristics are associated with opioid overdose following buprenorphine taper.

DESIGN, SETTING, AND PARTICIPANTS

This is a population-based, retrospective, cohort study of adults who were maintained on buprenorphine for at least 60 days and underwent a buprenorphine taper. The study was conducted in the Canadian province of Ontario, using linked administrative health data. New buprenorphine treatment episodes were accrued between January 1, 2013, and January 1, 2019, and the maximum follow-up was April 30, 2020. Data analysis was performed from December 2020 to August 2022.

EXPOSURES

The primary exposure of interest was time to taper initiation (≤1 year vs >1 year). Secondary exposures included mean rate of taper, percentage days during which the dose was decreasing, and taper duration.

MAIN OUTCOMES AND MEASURES

The primary outcome measure was time to fatal or nonfatal opioid overdose within 18 months following treatment discontinuation.

RESULTS

Among 5774 individuals, the median (IQR) age at index date was 34 (28-44) years, and 3462 individuals (60.0%) were male. Time to taper initiation longer than 1 year vs 1 year or less (6.73 vs 10.35 overdoses per 100 person-years; adjusted hazard ratio [aHR], 0.69; 95% CI, 0.48-0.997), a lower mean rate of taper (≤2 mg per month, 6.95 overdoses per 100 person-years; >2 to ≤4 mg per month, 11.48 overdoses per 100 person-years; >4 mg per month, 17.27 overdoses per 100 person-years; ≤2 mg per month vs >4 mg per month, aHR, 0.65; 95% CI, 0.46-0.91; >2 to ≤4 mg per month vs >4 mg per month, aHR, 0.69; 95% CI, 0.51-0.93), and dose decreases in 1.75% or less of days vs more than 3.50% of days during the taper period (5.87 vs 13.87 overdoses per 100 person-years; aHR, 0.64; 95% CI, 0.43-0.93) were associated with reduced risk of opioid overdose; however, taper duration was not.

CONCLUSIONS AND RELEVANCE

In this retrospective cohort study, buprenorphine tapers undertaken after at least 1 year of therapy, a slower rate of taper, and a lower percentage of days during which the dose was decreasing were associated with a significantly lower risk of opioid overdose, regardless of taper duration. These findings underscore the importance of a carefully planned taper and could contribute to reduction in opioid-related overdose death.

"You have to take this medication, but then you get punished for taking it:" lack of agency, choice, and fear of medications to treat opioid use disorder across the perinatal period

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 areas include improving uptake of shared decision-making to increase patient autonomy and agency, particularly among those in the earliest stages of recovery during pregnancy; ongoing education around perinatal MOUD safety and efficacy; detangling MOUD and neonatal withdrawal signs from mandated child protective services reporting; and improving gender-responsive and equitable care in substance use disorder treatment programs, including incorporating the utilization of home visiting services for dosing assessments and administration in the early postpartum period.

Perinatal Opioid Use Disorder Research, Race, and Racism: A Scoping Review

CONTEXT

Racial/ethnic inequities are well documented in both maternal-infant health and substance use disorder treatment outcomes.

OBJECTIVE

To systematically review research on maternal-infant dyads affected by opioid use disorder (OUD) to evaluate for racial/ethnic disparities in health utilization or outcomes and critically assess the reporting and inclusion of race/ethnicity data.

DATA SOURCES

Peer-reviewed literature in MEDLINE, Embase, and Web of Science from 2000 to 2020.

STUDY SELECTION

Research reporting health utilization and outcomes data on dyads affected by OUD during pregnancy through the infant's first birthday.

DATA EXTRACTION

We extracted data on race/ethnicity, study exposures/outcomes, how race/ethnicity data were analyzed, how authors discussed findings associated with race/ethnicity, and whether racism was mentioned as an explanation for findings.

RESULTS

Of 2023 articles reviewed, 152 quantitative and 17 qualitative studies were included. Among quantitative studies, 66% examined infant outcomes (n = 101). Three articles explicitly focused on evaluating racial/ethnic differences among dyads. Among quantitative studies, 112 mentioned race/ethnicity, 63 performed analyses assessing for differences between exposure groups, 27 identified racial/ethnic differences, 22 adjusted outcomes for race/ethnicity in multivariable analyses, and 11 presented adjusted models stratified by race/ethnicity. None of the qualitative studies addressed the role that race, ethnicity, or racism may have had on the presented themes.

CONCLUSIONS

Few studies were designed to evaluate racial/ethnic inequities among maternal-infant dyads affected by OUD. Data on race/ethnicity have been poorly reported in this literature. To achieve health equity across perinatal OUD, researchers should prioritize the inclusion of marginalized groups to better address the role that structural racism plays.

Explaining Racial-ethnic Disparities in the Receipt of Medication for Opioid Use Disorder during Pregnancy

OBJECTIVE

Factors contributing to racial and ethnic disparities in medication for opioid use disorder (MOUD) receipt during pregnancy are largely unknown. We quantified the contribution of individual, healthcare access and quality, and community factors to racial-ethnic disparities in MOUD during pregnancy and postpartum among Medicaid-enrolled pregnant women with opioid use disorder (OUD).

METHODS

This retrospective cohort study used regression and nonlinear decomposition to examine how individual, healthcare access and quality, and community factors explain racial-ethnic disparities in MOUD receipt among Medicaid-enrolled women with OUD who had a live birth from 2011 to 2017. The exposure was self-reported race and ethnicity. The outcomes were any MOUD receipt during pregnancy or postpartum. All factors included were identified from the literature.

RESULTS

Racial-ethnic disparities in individual, healthcare access and quality, and community factors explained 15.8% of the racial-ethnic disparity in MOUD receipt during pregnancy and 68.9% of the disparity in the postpartum period. Despite comparable healthcare utilization, non-White/Hispanic women were diagnosed with OUD 37 days later in pregnancy, on average, than non-Hispanic White women, which was the largest contributor to the racial-ethnic disparity in MOUD receipt during pregnancy (111.0%). The racial-ethnic disparity in MOUD receipt during pregnancy was the largest contributor (112.2%) to the racial-ethnic disparity in MOUD in the postpartum period.

CONCLUSIONS

Later diagnosis of OUD in pregnancy among non-White/Hispanic women partially explains the disparities in MOUD receipt in this population. Universal substance use screening earlier in pregnancy, combined with connecting patients to evidence-based and culturally competent care, is one approach that could close the observed racial-ethnic disparity in MOUD receipt.

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.
