The Impact of the Affordable Care Act Insurance Expansions on Opioid-Related Emergency Department Visits.
The authors leveraged ACA coverage expansions, including Medicaid expansion and Marketplaces, to study the impact of health insurance on opioid-related emergency department (ED) visits. They used ZIP-code–level ED utilization data from HCUP’s State Inpatient Databases (SID) and State Emergency Department Databases (SEDD) for 29 states. They found evidence of a dose-response relationship between pre-ACA uninsured and changes in ED visit rates in both expansion and non-expansion states: areas with higher uninsured rates prior to ACA saw larger reductions in opioid-related ED visits after the ACA took effect. The authors concluded that these findings suggest that increased insurance coverage may to help mitigate the opioid crisis.

Racial and ethnic disparities in opioid access and urine drug screening among older patients with poor-prognosis cancer near the end of life.
This research characterized racial and ethnic disparities and trends in opioid access and urine drug screening (UDS) among older patients dying of cancer, and to explore potential mechanisms. Among 18,549 non-Hispanic White (White), Black, and Hispanic Medicare decedents older than 65 years with poor-prognosis cancers, the authors examined 2007-2019 trends in opioid prescription fills and potency (morphine milligram equivalents [MMEs] per day [MMEDs]) near the end of life (EOL), defined as 30 days before death or hospice enrollment. They found that between 2007 and 2019, White, Black, and Hispanic decedents experienced steady declines in EOL opioid access and rapid expansion of UDS. Compared with White patients, Black and Hispanic patients were less likely to receive any opioid (Black, -4.3 percentage points; Hispanic, -3.6 percentage points) and long-acting opioids (Black, -3.1 percentage points; Hispanic, -2.2 percentage points). They also received lower daily doses (Black, -10.5 MMED; Hispanic, -9.1 MMED) and lower total doses (Black, -210 MMEs; Hispanic, -179 MMEs). Black patients were also more likely to undergo UDS (0.5 percentage points).

Are North Carolina clinicians delivering opioid use disorder treatment to Medicaid beneficiaries?
This study’s goal was to inform efforts to increase prescriptions of medications for opioid use disorder (MOUD) among Medicaid beneficiaries. A retrospective study of North Carolina licensed physicians, physician assistants, and nurse practitioners was conducted to estimate Medicaid participation prevalence among clinicians authorized to prescribe buprenorphine and to estimate the association between clinician characteristics and OUD care delivery to Medicaid beneficiaries. Outcomes looked for were indicators of any Medicaid professional claims and Medicaid claims data for buprenorphine and naltrexone. Licensure data from 2018 was merged with 2019 US Drug Enforcement Administration to identify clinicians who used the DEA waiver required to prescribe buprenorphine (n = 1714). Services by waivered clinicians to Medicare beneficiaries ranged from 67% of behavioral health clinicians to 82.9% of specialist physicians. Prevalence of prescribing buprenorphine to Medicaid beneficiaries ranged from 30.3% among specialist physicians to 51.6% among behavioral health clinicians.

Expanding access to medications for opioid use disorder through locally-initiated implementation.
The purpose of this study was to identify and describe locally- and internally-developed approaches to improve patient access to medication treatment for opioid use disorder (MOUD). The researchers utilized the Consolidated Framework for Implementation Research (CFIR) to guide qualitative interviews and ethnographic observations to examine the planning, design, and implementation of a locally-initiated process to expand access to MOUD. The study found that a self-appointed local team successfully developed and implemented a Primary Care-based Buprenorphine Clinic and E-Consult Service to expand access to MOUD to patients across the health care system, including national and local policy changes, identifying appropriate and widely supported models of care delivery and consultation, and increasing staff investment in the efforts by including them in collaborative planning and problem-solving. The study concluded that a local team can plan, develop and build new processes of care that are customized to meet local needs and contribute to long-term sustainability in the community.

Medicaid managed care: access to primary care providers who prescribe buprenorphine.
This study examined variation in access to in-network buprenorphine-prescribing primary care providers that can treat opioid use disorder among Medicaid managed care enrollees. Approximately 32.2% of Medicaid enrollees had fewer than one in-network network buprenorphine-prescribing primary care providers per 100,000 county residents. There was on average a greater number of in-network buprenorphine-prescribing primary care providers in states with higher compared with lower overdose death rates, but most enrollees lived in areas with a shortage of these providers. The authors found that a 25 percent higher network participation rate by prescribers compared with nonprescribers could improve the probability that enrollees see a prescriber by approximately 25 percent.
