Recreational marijuana laws and the misuse of prescription opioids: evidence from National Survey on Drug Use and Health microdata.
Using micro data from the National Survey on Drug Use and Health, researchers examined the relationship between recreational marijuana laws (RMLs) and the misuse of prescription opioids. They found that RML adoption reduced the likelihood of misusing prescription opioids; however, this initial effect appeared to dissipate 2 or 3 years after RML adoption, when the relationship to the likelihood of misusing prescription opioids became positive.

The role of formal policy to promote informed consent of psychotropic medications for youth in child welfare custody: a national examination.
The purpose of this sequential multi-method study was to propose a classification for the procedural elements of informed consent policies based upon existing child welfare policies and then explored whether formal state policies across the United States authorized these elements. The researchers conducted interviews with 58 key informants primarily from state child welfare agencies to identify a classification of procedural elements for informed consent of psychotropic medications. A legislative review of the 50 states and D.C. was then conducted to characterize whether formal policies endorsed each procedural element. Key informants reported five procedural elements in policy, and 23 states endorsed relevant legislation. Only two states specified all five procedural elements, and the content of any procedural elements varied considerably across policies.

Association of access to crisis intervention teams with county sociodemographic characteristics and state Medicaid policies and Its implications for a new mental health crisis lifeline.
This study’s objective was to assess county-level access to crisis intervention teams (CIS) for acute mental health issues in 2015 and 2020 and its association with area characteristics and state policies in 2020. This cross-sectional study included 10,430 facilities from the 2015 National Directory of Mental Health Treatment Facilities and 10,591 facilities from the 2020 National Directory of Mental Health Treatment Facilities, from 3142 US counties. Area measures included suicide, drug-related overdose mortality, rurality, and demographic characteristics. State-level policies included enactment of 5 Medicaid policies prior to 2020 and 2 recent policies intended to assist implementation of the 988 telephone lifeline. Most US residents (88%) lived in a county that had at least 1 facility offering CIT, although half of all US counties had no CIT facility. Counties without vs those with CIT access were less likely to be in states that expanded Medicare and in states that allow Medicaid to pay for short-term stays in psychiatric hospitals. Residents of counties without CIT access were more likely to be older (>55 years) and uninsured and were more likely to be rural.

Research to move policy - using evidence to advance health equity for substance use disorders.
This paper discusses ways that evidence-based research can advance health equity for substance use disorder (SUD) treatment. Racial and ethnic disparities in treatment access and outcomes have widened, despite substantial efforts to address the epidemic of overdose-related deaths in the US. Overdose rates are rising faster in Black, Latinx, and American Indian and Alaska Native populations than in White populations. Possible opportunities to address these disparities include addressing social determinants of health, implementing prevention measures, and supporting data science. The steps to ensure that research reduces disparities are to: 1) include members of underrepresented groups in the development of preventive interventions and treatments, 2) adequately recruit members of historically represented groups and ensure that studies are large enough to measure differences in outcomes according to race and ethnic group, 3) establish equitable partnerships with people who currently have or have had SUDS and their families and engage these groups in evidence production, 4) diversify the scientific workforce, and 4) have investigators measure the effects of policies and interventions on equity.

Carve-out plan financial requirements associated with national behavioral health parity.
The authors examined changes in carve-out financial requirements following the Mental Health Parity and Addiction Equity Act (MHPAEA). They found that the MHPAEA was associated with increased generosity in most observed financial requirements, but increased use of deductibles may have reduced generosity for some patients.

Exploring the psychiatrist-industry financial relationship: insight from the open payment data of Centers for Medicare and Medicaid Services.
The Physician Payments Sunshine Act (PPSA) requires reporting of financial payments by pharmaceutical and medical device companies to teaching hospitals and individual physicians in the United States. In this study, industry payments made to psychiatrists were quantified. The investigators found that over half of active psychiatrists (55.7%) received some form of payments from pharmaceutical manufacturers.

The impact Of Medicare's mental health cost-sharing parity on use of mental health care services.
This study examined the impact of Medicare’s mental health cost-sharing parity on use of mental health care services, which was phased in from 2010 to 2014. The authors assessed whether the reduction in mental health cost sharing was associated with changes in specialty and primary care outpatient mental health visits and psychotropic medication fills. They compared people with Medicare and private insurance before and after implementation. Medicare beneficiaries’ use of psychotropic medication increased after implementation but there was not a detectable change in visits.

The Mental Health Parity and Addiction Equity Act (MHPAEA) evaluation study: did parity differentially affect substance use disorder and mental health benefits offered by behavioral healthcare carve-out and carve-in plans?
The purpose of the stud was to assess whether implementation of the Mental Health Parity and Addiction Equity Act (MHPAEA) was associated with: 1. Reduced differences in financial requirements (i.e., copayments and coinsurance) for substance use disorder (SUD) versus specialty mental health (MH) care and 2. Reductions in the level of cost-sharing for SUD-specific services.

Medicaid benefits for addiction treatment expanded after implementation of the Affordable Care Act.
This study looked at the effects the Affordable Care Act (ACA) had on Medicaid benefits for addiction treatment. The ACA established a minimum standard of benefits and required state Medicaid programs to make changes to their treatment benefits. Researchers surveyed all 50 states and the District of Columbia in 2014 and 2017 when the ACA requirements came into effect. There was a substantial increase in benefits with a decrease in annual service limits of over 50 percent. There was a large reduction in preauthorization requirements for medications to treat opioid use disorder as well as other reductions in preauthorizations.

Psychological distress and enrollment in Medicaid.
Adults with poor mental health may want and need insurance to obtain care, but symptoms may impede enrollment into public health insurance. The enrollment response to Medicaid expansions prior to the Affordable Care Act was stronger for adults symptomatic of psychological distress compared with adults without distress and compared to adults with chronic physical health problems.

The Mental Health Parity and Addiction Equity Act evaluation study: impact on specialty behavioral healthcare utilization and spending among enrollees with substance use disorders.
The purpose of this study was to determine whether Mental Health Parity and Addiction Equity Act (MHPAEA) was associated with increased behavioral health expenditures and utilization among a population with substance use disorder (SUD) diagnoses. The investigators found that MHPAEA was associated with modest increases in total, plan, and patient out-of-pocket spending and outpatient and inpatient utilization.

Assessing the individual, neighborhood, and policy predictors of disparities in mental health care.
This study assessed individual- and area-level predictors of racial/ethnic disparities in mental health care episodes for adults with psychiatric illness. It found that racial/ethnic disparities arise because minorities are more likely to live in neighborhoods where treatment initiation is low, rather than because of a differential influence of neighborhood disadvantage on treatment initiation for minorities compared with whites.

Racial and ethnic disparities among the remaining uninsured young adults with behavioral health disorders after the ACA expansion of dependent coverage.
The objective of this study is to explore the population characteristics of the remaining uninsured individuals with and without behavioral health disorders (BHDs) and to examine whether the factors that contribute to racial and ethnic disparities in the likelihood of being uninsured were different after ACA. The major factor associated with the ethnic disparity among those with BHDs was the immigrant status of Latinos, and the major factor associated with racial disparity was geographic location.

The Mental Health Parity and Addiction Equity Act (MHPAEA) evaluation study: impact on quantitative treatment limits.
This study assessed Mental Health Parity and Addiction Equity Act’s (MHPAEA) effect on the prevalence of behavioral health quantitative treatment limits (QTLs). It concluded that, before MHPAEA, QTLs were common. Postimplementation, virtually all plans dropped such limits, suggesting that MHPAEA was effective at eliminating QTLs.

Access to mental health care increased but not for substance use, while disparities remain.
The researchers assessed whether early implementation of Affordable Care Act (ACA) Medicaid expansion and state health insurance exchanges increased access to mental health and substance use treatment among those in need and whether these changes differed by racial/ethnic group. They found that mental health treatment rates increased significantly but found no evidence of a reduction in the wide racial/ethnic disparities in mental health treatment that preceded ACA expansion from 2005 to 2013.
