The impact of Medicaid expansion on postpartum health care utilization among pregnant women with opioid use disorder.

ABSTRACT: Background: Opioid use disorder (OUD) during pregnancy has increased dramatically over the past decade, as have associated adverse maternal health outcomes. Although Medicaid has long been the largest payer for deliveries in the United States, states' decisions to expand Medicaid eligibility to low-income adults has the potential to increase access to care for women in the postpartum period. This study aimed to determine the impact of the 2015 Pennsylvania Medicaid expansion on postpartum insurance coverage and preventive care utilization among pregnant women with opioid use disorder (OUD). Methods: In 2017, we conducted a retrospective cohort study using 2013-2015 administrative Medicaid data provided by the Pennsylvania Department of Human Services. We identified 1562 women with opioid use disorder who had a live birth delivery in a pre-Medicaid expansion or post-expansion study period. We compared length of continuous enrollment in Medicaid following delivery, postpartum visit attendance, and contraception initiation between groups. Results: More women in the post-expansion group remained enrolled in Medicaid at 300?days postpartum, relative to the pre-expansion group (87% vs. 81%). Medicaid expansion was not associated with differences in postpartum visit attendance or contraceptive use. However, women who remained enrolled in Medicaid for at least 300?days post delivery had an increased odds of postpartum visit attendance (odds ratio [OR]: 1.6, 95% confidence interval [CI]: 1.04, 2.4). Conclusion: The rate of continuous Medicaid enrollment among postpartum women with OUD was significantly higher after expansion, whereas rates of preventive care utilization were unaffected. Although improving insurance coverage for women with OUD is an important step to improve access to recommended preventive care, additional efforts are needed to ensure utilization of such care.

Project description:BackgroundOpioid use disorder (OUD) among women delivering at a hospital has increased 400% from 1999-2014 in the United States. From the years 2007 to 2016, opioid-related mortality during pregnancy increased over 200%, and drug-overdose deaths made up nearly 10% of all pregnancy-associated mortality in 2016 in the US. Disproportionately higher rates of neonatal opioid withdrawal syndrome (NOWS) have been reported in rural areas of the country, suggesting that perinatal OUD is a pressing issue among these communities. There is an urgent need for comprehensive, evidence-based treatment services for pregnant women experiencing OUD. The purpose of this article is to describe a study protocol aimed at developing and evaluating a perinatal OUD curriculum, enhancing evidence-based perinatal OUD treatment in a rural setting, and evaluating the implementation of such collaborative care for perinatal OUD.MethodsThis two-year study employed a one group, repeated measures, hybrid type-1 effectiveness-implementation design. This study delivered interventions at 2 levels, both targeting improvement of care for pregnant women with OUD. The first area of focus was at the community healthcare provider-level, which aimed to evaluate the acceptability and feasibility of perinatal OUD education across time and to improve provider education by increasing knowledge specific to: MOUD provision; screening, brief intervention, and referral to treatment (SBIRT) utilization; and NOWS treatment. The second area of intervention focus was at the patient-level, which assessed the preliminary effect of perinatal OUD provider education in promoting illicit opioid abstinence and treatment engagement among pregnant women with OUD. We adopted constructs from the Consolidated Framework for Implementation Research (CFIR) to assess contextual factors that may influence implementation, and the Reach, Effectiveness, Adoption, Implementation, and Maintenance (RE-AIM) model to comprehensively evaluate implementation outcomes.DiscussionThis article presents the protocol of an implementation study that is employing the CFIR and RE-AIM frameworks to implement and evaluate a perinatal OUD education and service coordination program in two rural counties. This protocol could serve as a model for clinicians and researchers seeking to implement improvements in perinatal care for women with OUD in other rural communities.

Project description:ImportanceAccess to postpartum care is restricted for low-income women who are recent or undocumented immigrants enrolled in Emergency Medicaid.ObjectiveTo examine the association of a policy extending postpartum coverage to Emergency Medicaid recipients with attendance at postpartum visits and use of postpartum contraception.Design, setting, and participantsThis cohort study linked Medicaid claims and birth certificate data from 2010 to 2019 to examine changes in postpartum care coverage on postpartum care and contraception use. A difference-in-difference design was used to compare the rollout of postpartum coverage in Oregon with a comparison state, South Carolina, which did not cover postpartum care. The study used 2 distinct assumptions to conduct the analyses: first, preintervention differences in postpartum visit attendance and contraceptive use would have remained constant if the policy expanding coverage had not been passed (parallel trends assumption), and second, differences in preintervention trends would have continued without the policy change (differential trend assumption). Data analysis was performed from September 2020 to October 2021.ExposuresMedicaid coverage of postpartum care.Main outcomes and measuresAttendance at postpartum visits and postpartum contraceptive use, defined as receipt of any contraceptive method within 60 days of delivery.ResultsThe study population consisted of 27 667 live births among 23 971 women (mean [SD] age, 29.4 [6.0] years) enrolled in Emergency Medicaid. The majority of all births were to multiparous women (21 289 women [76.9%]; standardized mean difference [SMD] = 0.08) and were delivered vaginally (20 042 births [72.4%]; SMD = 0.03) and at term (25 502 births [92.2%]; SMD = 0.01). Following Oregon's expansion of postpartum coverage to women in Emergency Medicaid, there was a large and significant increase in postpartum care visits and contraceptive use. Assuming parallel trends, postpartum care attendance increased by 40.6 percentage points (95% CI, 34.1-47.1 percentage points; P < .001) following the policy change. Under the differential trends assumption, postpartum visits increased by 47.9 percentage points (95% CI, 41.3-54.6 percentage points; P < .001). Postpartum contraception use increased similarly. Under the parallel trends assumption, postpartum contraception within 60 days increased by 33.2 percentage points (95% CI, 31.1-35.4 percentage points; P < .001). Assuming differential trends, postpartum contraception increased by 28.2 percentage points (95% CI, 25.8-30.6 percentage points; P < .001).Conclusions and relevanceThese findings suggest that expanding Emergency Medicaid benefits to include postpartum care is associated with significant improvements in receipt of postpartum care and contraceptive use.

Project description:BACKGROUND:Criminal justice involvement is common among pregnant women with opioid use disorder (OUD). Medications for OUD improve pregnancy-related outcomes, but trends in treatment data among justice-involved pregnant women are limited. We sought to examine trends in medications for OUD among pregnant women referred to treatment by criminal justice agencies and other sources before and after the Affordable Care Act's Medicaid expansion. METHODS AND FINDINGS:We conducted a serial, cross-sectional analysis using 1992-2017 data from pregnant women admitted to treatment facilities for OUD using a national survey of substance use treatment facilities in the United States (N = 131,838). We used multiple logistic regression and difference-in-differences methods to assess trends in medications for OUD by referral source. Women in the sample were predominantly aged 18-29 (63.3%), white non-Hispanic, high school graduates, and not employed. Over the study period, 26.3% (95% CI 25.7-27.0) of pregnant women referred by criminal justice agencies received medications for OUD, which was significantly less than those with individual referrals (adjusted rate ratio [ARR] 0.45, 95% CI 0.43-0.46; P < 0.001) or those referred from other sources (ARR 0.51, 95% CI 0.50-0.53; P < 0.001). Among pregnant women referred by criminal justice agencies, receipt of medications for OUD increased significantly more in states that expanded Medicaid (n = 32) compared with nonexpansion states (n = 18) (adjusted difference-in-differences: 12.0 percentage points, 95% CI 1.0-23.0; P = 0.03). Limitations of this study include encounters that are at treatment centers only and that do not encompass buprenorphine prescribed in ambulatory care settings, prisons, or jails. CONCLUSIONS:Pregnant women with OUD referred by criminal justice agencies received evidence-based treatment at lower rates than women referred through other sources. Improving access to medications for OUD for pregnant women referred by criminal justice agencies could provide public health benefits to mothers, infants, and communities. Medicaid expansion is a potential mechanism for expanding access to evidence-based treatment for pregnant women in the US.

Project description:ObjectiveTo assess trends in polysubstance use among pregnant women with opioid use disorder in the United States.MethodsWe conducted a time trend analysis of pooled, cross-sectional data from the National Inpatient Sample, an annual nationally representative sample of U.S. hospital discharge data. Among 38.0 million females aged 15-44 years with a hospitalization for delivery from 2007 to 2016, we identified 172,335 pregnant women with an International Classification of Diseases, Ninth Revision, Clinical Modification or International Classification of Diseases, Tenth Revision, Clinical Modification diagnosis of opioid use disorder. Polysubstance use among pregnant women with opioid use disorder was defined as at least one co-occurring diagnosis of other substance use, including alcohol, amphetamine, cannabis, cocaine, sedative, or tobacco. We fit weighted multivariable logistic regression models to produce nationally representative estimates, including an interaction between year and rural compared with urban county of residence; controlled for age, race, and insurance type. Average predicted probabilities and 95% CIs were derived from regression results.ResultsPolysubstance use among women with opioid use disorder increased from 60.5% (95% CI 58.3-62.8%) to 64.1% (95% CI 62.8%-65.3%). Differential time trends in polysubstance use among women with opioid use disorder were found in rural compared with urban counties. Large increases in amphetamine use occurred among those in both rural and urban counties (255.4%; 95% CI 90.5-562.9% and 150.7%; 95% CI 78.2-52.7%, respectively), similarly to tobacco use (30.4%; 95% CI 16.9-45.4% and 23.2%; 95% CI 15.3-31.6%, respectively). Cocaine use diagnoses declined among women with opioid use disorder at delivery in rural (-70.5%; 95% CI -80.4% to -55.5%) and urban (-61.9%; 95% CI -67.6% to -55.1%) counties. Alcohol use diagnoses among those with opioid use disorder declined -57% (95% CI -70.8% to -37.7%) in urban counties but did not change among those in rural counties.ConclusionOver the past decade, polysubstance use among pregnant women with opioid use disorder has increased more rapidly in rural compared with urban counties in the United States, with amphetamines and tobacco use increasing most rapidly.
