We described Medicaid-insured women by receipt of perinatal opioid use disorder (OUD) treatment; and trends and disparities in treatment. Using 2007 to 2012 Medicaid Analytic eXtract data from 45 states and D.C., we identified deliveries among women with OUD. Regressions modeled the association between patient characteristics and receipt of any OUD treatment, medication for OUD (MOUD), and counseling alone during the perinatal period. Rates of any OUD treatment and MOUD for women with perinatal OUD increased over the study period, but trends differed by subgroup. Compared with non-Hispanic White women, Black and American Indian/Alaskan Native (AI/AN) women were less likely to receive any OUD treatment, and Black women were less likely to receive MOUD. Over time, the disparity in receipt of MOUD between Black and White women increased. Overall gains in OUD treatment were driven by improvements in perinatal OUD care for White women and obscured disparities for Black and AI/AN women.

OBJECTIVE: To assess trends in use of long-acting opioids during delivery hospitalizations. METHODS: The Perspective database, an administrative inpatient database that includes medication receipt, was analyzed to evaluate patterns of long-acting opioid use during delivery hospitalizations from January 2006 through March 2015. Medications evaluated included methadone, formulations including buprenorphine and extended-release formulations of oxycodone, morphine, fentanyl, and other opioids. Temporal trends in use of these medications were determined. Unadjusted and adjusted models evaluating the role of demographic and hospital factors were created evaluating both use of these medications and risk for severe morbidity. Risk for severe morbidity was determined based on Centers for Disease Control and Prevention criteria. RESULTS: Our analysis included 2,994,630 delivery hospitalizations meeting study criteria. Over the entire study period, use of long-acting opioids increased significantly from 457 to 844 per 100,000 deliveries. Although buprenorphine and methadone use increased, use of other long-acting opioids decreased. In 2006, methadone and buprenorphine accounted for less than one third of all long-acting opioids used during delivery hospitalizations. By 2015, buprenorphine and methadone represented 73.5% of long-acting opioids used. In adjusted and unadjusted models, risk for severe morbidity was significantly lower with buprenorphine or methadone compared with other long-acting opioids. Restricting the cohort to only women with drug abuse or dependence, risk for severe morbidity was lower with methadone and buprenorphine than without any long-acting opioids. CONCLUSION: Increased use of methadone and buprenorphine in this study supports the feasibility of use of these medications during pregnancy and uptake of clinical recommendations for women with opioid use disorder. Use of methadone and buprenorphine is associated with decreased maternal morbidity, although causation cannot be presumed from this study model.

BACKGROUND: Identifying solutions to the continued rise in overdose deaths is a public health priority. However, there is evidence of change in recent substance type associated with morbidity and mortality. To better understand the continued rise in overdose deaths, in particular those attributed to opioid and stimulant use disorders, increased knowledge of patterns of use is needed. METHODS: Retrospective cohort study of Veterans diagnosed with an opioid or stimulant use disorder between 2005 and 2019. The outcome of interest was diagnosis of substance use disorders, specifically examining combinations of opioid and stimulant use disorders among this population. RESULTS: A total of 1932,188 Veterans were diagnosed with at least one substance use disorder (SUD) during the study period, 2005 through 2019. While the annual prevalence of opioid use disorder (OUD) diagnoses increased more than 155%, OUD diagnoses absent of any other SUD diagnosis increased by an average of 6.9% (95% CI, 6.4, 7.5) per year between 2005 and 2019. Between 2011 and 2019, diagnoses of co-morbid methamphetamine use disorder (MUD) and OUD increased at a higher rate than other SUD combinations. CONCLUSIONS: The prevalence of comorbid SUD, in particular co-occurring opioid and methamphetamine use disorder, increased at a higher rate than other combinations between 2005 and 2019. These findings underscore the urgent need to offer patients a combination of evidence-based treatments for each co-morbid SUD, such MOUD and contingency management for persons with comorbid opioid and methamphetamine use disorders.
