Opioid Use Disorder in Pregnancy

Implementation of perinatal quality collaborative statewide initiative improves obstetrical opioid use disorder care and outcomes

BACKGROUND

Maternal deaths resulting from opioid use disorder have been increasing across the United States. Opioid use disorder among pregnant persons is associated with adverse pregnancy outcomes, including preterm birth, along with racial disparities in optimal opioid use disorder care.

OBJECTIVE

This study aimed to evaluate whether the Illinois Perinatal Quality Collaborative implementation of the Mothers and Newborns affected by Opioids - Obstetric quality improvement initiative was associated with improvement in opioid use disorder identification, provision of optimal opioid use disorder care for birthing patients, and reduction in racial gaps in optimal opioid use disorder care.

STUDY DESIGN

Using a prospective cohort design, hospitals reported monthly key measures for all patients with opioid use disorder at delivery between July 2018 and December 2020. The Illinois Perinatal Quality Collaborative facilitates collaborative learning opportunities, rapid response data, and quality improvement support. Generalized linear mixed-effects regression models were used to evaluate improvement in optimal opioid use disorder care, including increases in linkages to medication-assisted treatment, recovery treatment services, and naloxone counseling across time, and to determine whether optimal opioid use disorder care was associated with positive outcomes, such as lower odds of preterm birth.

RESULTS

A total of 91 hospitals submitted data on 2095 pregnant persons with opioid use disorder. For the primary outcomes, the rates of patients receiving medication-assisted treatment and recovery treatment services improved across the initiative from 41% to 78% and 48% to 67%, respectively. For the secondary outcomes, the receipt of recovery treatment services and both recovery treatment services and medication-assisted treatment provided prenatally before delivery admission was associated with lower odds of preterm birth (adjusted odds ratio: 0.67 [95% confidence interval, 0.50-0.91] and 0.49 [95% confidence interval, 0.31-0.75], respectively). During the first quarter of the initiative, Black patients with opioid use disorder were less likely to be linked to medication-assisted treatment than White patients (23% vs 48%, respectively); however, an increase in medication-assisted treatment rates across the initiative occurred for all patients, with the greatest improvement for Black patients with an associated reduction in this disparity gap with >70% of both Black and White patients linked to medication-assisted treatment.

CONCLUSION

The Mothers and Newborns affected by Opioids - Obstetric initiative was associated with improvement in optimal opioid use disorder care for pregnant patients across Illinois hospitals, additionally racial disparities in opioid use disorder care was reduced across the initiative. Our findings implicate how optimal opioid use disorder care can improve pregnancy outcomes and close persistent racial gaps for pregnant individuals with opioid use disorder.

Use of Psychoactive Substances during the Perinatal Period: Guidelines for Interventions during the Perinatal Period from the French National College of Midwives

Based on their clinical practice and an extensive review of the literature, the authors propose a framework of procedures to be followed to provide services to all women of childbearing age who use psychoactive substances (alcohol, cannabis, cocaine, amphetamines, and opioids), especially during pregnancy or during the postpartum and breastfeeding periods, in view of their individual situations and environmental contexts.

Lessons Learned From the Implementation of an Integrated Prenatal Opioid Use Disorder Program

OBJECTIVE

To evaluate key lessons learned from efforts at increasing engagement in integrated prenatal and opioid use disorder services.

DESIGN

An interdisciplinary team consisting of a board-certified obstetrician and registered nurse led the implementation of this multipronged approach driven by several plan-do-study-act cycles to develop an integrated prenatal and opioid use disorder program.

SETTING/LOCAL PROBLEM

An urban community health center in Chicago, Illinois, where mental health issues, including substance use, are the leading cause of death for pregnant people.

PARTICIPANTS

Connections were made with local harm reduction agencies, substance use treatment facilities, and community outreach programs to develop partnerships with organizations providing existing addiction and maternal-child services in the community.

INTERVENTION/MEASURES

Partnership building was achieved through organization needs assessments, dissemination of information about integrated services, and sustained communication. Referral workflow guides and patient education cards were created and distributed to community partners. Incoming referrals were tracked at the clinic site. Use of the referral materials was evaluated via online surveys distributed to community partners.

RESULTS

In the 18 weeks of enhanced integration, three patients engaged in services and were initiated on medication for opioid use disorder, two of whom had been referred from agencies targeted in the outreach efforts. Surveys showed that community partners believe the referral guides were easy to use and that the harm reduction information on the patient cards was useful.

CONCLUSION

An urban community health center was equipped to provide comprehensive, integrated services to pregnant people with opioid use disorder, but barriers such as community unawareness and stigma impeded engagement. Sustained collaboration with community partners serving pregnant people with opioid use disorder supports program development and linkage to care. Integrated prenatal and opioid use disorder care is feasible, us destigmatizing in nature, and can lead to improved maternal and fetal outcomes.

Estimating the impact on initiating medications for opioid use disorder of state policies expanding Medicaid and prohibiting substance use during pregnancy

BACKGROUND

Medicaid expansion increased access to addiction treatment services for pregnant women. However, states' imposition of civil or criminal child abuse sanctions for drug use during pregnancy could inhibit access to treatment. We estimated the effects of Medicaid expansion on pregnant women's medications for opioid use disorder (MOUD) use, and its interaction with statutes that prohibit substance use during pregnancy.

METHODS

Using the Treatment Episode Dataset for Discharge (2010-2018), we identified the initial treatment episode of pregnant women with opioid use disorder (OUD). We described changes in MOUD use and estimated adjusted difference-in-differences and event study models to evaluate differences in changes in MOUD between states that prohibit substance use during pregnancy and states that do not.

FINDINGS

Among a total of 16,070 treatment episodes for pregnant women with OUD from 2010 to 2018, most (74%) were in states that expanded Medicaid. By one year post-expansion, the proportion of episodes receiving MOUD in states not prohibit substance use during pregnancy increased by 8.7% points (95% CI: 2.7, 14.7) from the pre-expansion period compared to a 5.6% point increase in states prohibiting substance use during pregnancy (95% CI: -3.3, 14.8). In adjusted event study analysis, the expansion was associated with an increase in MOUD use by 15.3% by year 2 in states not prohibiting versus 1.5% percentage points in states prohibiting substance use during pregnancy, respectively.

CONCLUSIONS

State policies prohibiting substance use during pregnancy may limit the salutary effects of Medicaid expansion for pregnant women who could benefit from MOUD treatment.

Clinical care of neonates undergoing opioid withdrawal in the immediate postpartum period

As the opioid epidemic escalates in westernized countries around the world, chronic opioid use during pregnancy has become a growing public health issue. There are increasing concerns that chronic maternal opioid use might adversely affect the developing fetal brain. Furthermore, the sudden discontinuation of the trans-placental opioid supply at birth puts newborns at acute risk for neonatal opioid withdrawal syndrome (NOWS). NOWS is a multi-system disorder that has been identified in approximately 50-80% of neonates exposed to opioids due to chronic maternal use. Clinically, NOWS affects the central and autonomic nervous systems as well as the gastrointestinal and respiratory tracts. The clinical features of NOWS include hyperirritability, high-pitched crying, restlessness, tremors, poor sleep, agitation, seizures, sweating, fever, poor feeding, regurgitation, diarrhea, and tachypnea. NOWS is currently diagnosed using a clinical scoring tool followed by toxicological confirmation of the presence of opioids in meconium or tissue specimens. The first-line treatments for NOWS are non-pharmacologic comfort measures. If these measures fail, neonates may be treated with opioids and/or sedatives. Since the severity of NOWS can be highly variable, it is quite difficult to predict which opioid-exposed neonates will require pharmacotherapy and prolonged hospitalization. Factors associated with maternal polysubstance use, including the use of illicit substances and tobacco, have been associated with the increased severity and duration of NOWS. Since neonates with NOWS are at increased risk for long-term adverse neurodevelopmental outcomes, ongoing monitoring beyond the neonatal period is essential.

Knowledge and Attitudes of Maternity Nurses and Ancillary Team Members about Substance Addiction during Pregnancy and Postpartum

OBJECTIVE

To describe knowledge and attitudes of maternity nurses and other ancillary direct caregivers about addictive substance use by pregnant women and new mothers and to evaluate their perceptions of role preparation, resources available, and educational needs.

STUDY DESIGN METHODS

We surveyed maternity nurses and ancillary members of the maternity care team to assess knowledge and attitudes about caring for women with addictive substance use. Data were analyzed using descriptive, parametric, and nonparametric statistics.

RESULTS

Respondents (N = 109) from a southwestern Magnet community hospital were 100% female, predominantly nurses (89%), and worked mostly on mother-baby or labor and delivery units. They had high average knowledge scores and most had positive attitudes. When asked about preparation to care for pregnant women and new mothers with addictive substance use, some perceived that they were not able to carry out their role due to lack of knowledge.

CLINICAL IMPLICATIONS

Findings suggest most maternity nurses have the knowledge and skills they believe are needed to care for women who use addictive substances during pregnancy and postpartum. Most have positive attitudes, but approximately one third may need interventions to encourage and further support empathy and acceptance. Education and skill-building for maternity nurses and other team members related to caring for women using addictive substances may be worth consideration; however, there is minimal evidence of their efficacy. Evaluations of these types of programs are needed in maternity settings.

Antepartum Drug Dependence and Pregnancy- or Birth-related Complications: A Cross-sectional Study of 19 Million Inpatients

Objective To evaluate the demographic characteristics, hospitalization outcomes [severity, length of stay (LOS), and total expense], and comorbidities in pregnant patients with antepartum drug dependence (ADD). Methods We used the national inpatient sample (NIS) and included 19,170,561 female patients (age: 12-40 years) hospitalized for pregnancy- or birth-related complications and grouped by co-diagnosis of ADD. We used descriptive statistics and Pearson's chi-square test for categorical data and independent sample T-test for the continuous data to measure the differences in demographic and hospital outcomes. A logistic regression model was used to evaluate the odds ratio (OR) for medical and psychiatric comorbidities. Results The hospitalizations with ADD declined initially, from 2010 to 2011, followed by an increase of 50% from 2011 to 2014. White pregnant females (77.5%), and those from low-income families (<25th percentile, 37.1 %) had comorbid ADD. Among medical comorbidities, iron-deficiency anemia was the most prevalent condition in pregnant inpatients (12.0% in ADD vs. 9.2% in non-ADD) followed by obesity and hypertension. Depression (12.9%) was the most prevalent psychiatric comorbidity in ADD inpatients followed by comorbid psychosis (three-fold higher odds). Among patients with substance use disorder (SUD), opioid abuse was the most prevalent one (67.3%) followed by cannabis (11.2%), cocaine (5.7%), amphetamine (4.0%), and alcohol (2.4%). Half of the pregnant inpatients with ADD had moderate severity of illness due to pregnancy or birth-related complications with four-fold higher odds [95% confidence interval (CI): 3.67-8.88]. They also had a higher LOS with a mean difference of 0.88 days (95% CI: 0.904-0.865) and had incurred higher total charges, by USD 3,797 (95% CI: 3,927-3,666), per inpatient admission for pregnancy- or birth-related complications compared to non-ADD inpatients Conclusion ADD is associated with the worsening of severity of illness in pregnancy- or birth-related complications and requires acute inpatient care that leads to increased healthcare-related economic burden. The integration of SUD services with primary or maternal care is required to improve outcomes in at-risk women in the reproductive age group.

Maternity Care for Pregnant Women with Opioid Use Disorder: A Review

Opioid misuse is a problem that is complex and widespread. Opioid misuse rates are rising across all US demographics, including among pregnant women. The opioid epidemic brings a unique set of challenges for maternity health care providers, ranging from ethical considerations to the complex health needs and risks for both woman and fetus. This article addresses care for pregnant women during the antepartum, intrapartum, and postpartum periods through the lens of the opioid epidemic, including screening and counseling, an interprofessional approach to prenatal care, legal considerations, and considerations for care during labor and birth and postpartum. Providers can be trained to identify at-risk women through the evidence-based process of Screening, Brief Intervention, and Referral to Treatment (SBIRT) and connect them with the appropriate care to optimize outcomes. Women at moderate risk of opioid use disorder can be engaged in a brief conversation with their provider to discuss risks and enhance motivation for healthy behaviors.  Women with risky opioid use can be given a warm referral to pharmacologic treatment programs, ideally comprehensive prenatal treatment programs where available (a warm referral is a term used when a provider, with the patient's permission, contacts another provider or another service him or herself rather than providing a phone number and referral number). Evidence regarding care for the pregnant woman with opioid use disorder and practical clinical recommendations are provided.

Opioid use disorder is associated with increased mortality and morbidity in patients with gastroparesis

Background

Opioid use disorder (OUD) epidemic has been declared a nationwide public health emergency by the Department of Health and Human Services. There are limited data regarding OUD in patients with gastroparesis. This study aimed to evaluate the impact of OUD on the outcomes in patients hospitalized with gastroparesis and to delineate the trends associated with OUD and gastroparesis using a nationally representative sample.

Methods

We used the National (Nationwide) Inpatient Sample database from 2005-2014 to identify patients hospitalized with a primary diagnosis of gastroparesis (ICD 9 Code: 536.3) and a concurrent diagnosis of OUD. We used Pearson chi-square analysis to compare demographics, the independent samples t-test to assess differences in length of stay and cost of care, and multivariate regression analysis to adjust for confounders.

Results

Between 2005 and 2014, a total of 145,700 patients with a primary diagnosis of gastroparesis were hospitalized in the United States, of whom 4519 (3.1%) had a concurrent diagnosis of OUD. The prevalence of OUD in gastroparesis doubled from 2.1% in 2005 to 4.3% in 2014. After adjusting for confounders, patients with OUD had greater in-hospital mortality (adjusted odds ratio 2.7, 95% confidence interval: 2.1-3.5). Patients with OUD also had significantly longer hospital stays and higher costs. Independent predictors of OUD in patients with gastroparesis were younger age, female sex, alcohol use, depression, and Medicaid insurance.

Conclusion

OUD in patients with gastroparesis is associated with greater mortality and healthcare resource utilization.
