Examining differences in opioid deaths by race in North Carolina following the STOP Act, 2010-2019.
This study used State-level secondary data to examine the impact of North Carolina's 2017 STOP Act on opioid overdose deaths by race. The results showed that the opioid overdose death rate among the White population decreased following the STOP Act, but found no significant change among the Black/African American population. The authors concluded that these findings have implications for health equity and may inform the development of future substance use policies.

Impact of opioid law on prescriptions and satisfaction of pediatric burn and orthopedic patients: an epidemiologic study.
This retrospective chart review study’s goal was to determine the reduction in prescribed opioid pain dosage units to pediatric patients experiencing acute pain and to assess patient satisfaction with pain control 90-day post discharge following the 2017 Ohio opioid prescribing cap law. The cohort included 960 pediatric (age 0-18 years) burn injury and knee arthroscopy patients treated between August 1, 2015-August 31, 2019. In addition, legal guardians prospectively completed a survey for a convenience sample of 50 patients. From pre-law to post-law, there was a significant decrease within the burn and knee cohorts in the median days (1.7 to 1.0 and 5.0 to 3.8, respectively) and median total morphine milligram equivalents (MMEs) prescribed (15.0 to 2.5 and 150.0 to 90.0, respectively). Results from the prospective survey showed that more than half of participants were satisfied (72% burn and 68% knee) with their pain control and felt they received the right amount of medication (84% burn and 56% knee).

Impact of state opioid laws on prescribing in trauma patients.
In this cross-sectional study, researchers compared oral morphine equivalents prescribed at discharge before and after the implementation of Michigan's Public Act 251, which established a state-wide policy that limited opioid prescriptions for acute pain to a 7-day supply. Subjects were adult patients who received oral opioids at discharge from a Level 1 trauma center. The findings indicated that prescription amounts for opioids in trauma patients decreased by approximately one-half following the implementation of Public Act 251; there was no compensatory increase in subsequent refill prescriptions. The researchers concluded that further work is needed to evaluate the effect of such policies on pain management and functional recovery after injury.

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.

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.

Spatiotemporal analysis of the association between pain management clinic laws and opioid prescribing and overdose deaths.
The authors investigated the impact of pain management clinic laws. They analyzed data on county-level, opioid overdose deaths via the National Vital Statistics System and patients filling long-duration or high-dose opioid prescriptions in the US 2010-2018. Their findings suggested that laws with criminal penalties were associated with intended reductions in high-risk opioid prescribing and some opioid overdoses but raised concerns regarding unintended consequences on heroin/synthetic overdoses.

Changes in opioid prescribing following the implementation of state policies limiting morphine equivalent daily dose in a commercially insured population.
The study’s objective was to evaluate the impact of state-level morphine equivalent daily dose (MEDD) policies on opioid prescribing among the privately insured using claims data from 9 policy states and 2 control states and a comparative interrupted time series design. Findings showed that MEDD policies were associated with decreased use of any opioids relative to control states, but with no change in high-dose prescribing. Recommendations included further research to understand the mechanisms through which MEDD policies may influence prescribing behavior.

Medical marijuana laws, marijuana use, and opioid-related outcomes among women in the United States.
This study examined whether state medical marijuana laws (MMLs) was associated with lower levels of opioid-related outcomes. Data was drawn from the 2002-2014 National Survey on Drug Use and Health to compare opioid misuse in states with and without MMLs among all women, pregnant women, and parenting women. It also invested the impact of MMLs on marijuana use and marijuana use disorder. There was found to be no association of MMLs with opioid misuse, opioid misuse initiation, or opioid use disorder among all women, pregnant women and parenting women. However there was a positive correlation with marijuana use and marijuana use disorder among all women and women with children. MMLs were also associated with an increase in the frequency of opioid misuse in pregnant women and a decrease in the frequency of opioid misuse for parenting women.

Association of state-level opioid-reduction policies with pediatric opioid poisoning.
Opioid-reduction policies have been enacted by US states to address the opioid epidemic. Evidence of an association between policy implementation and decreased rates of pediatric opioid poisoning provides further justification for expanded implementation of these policies. The purpose of this study was to examine the association of 3 state-level opioid-reduction policies with the rate of opioid poisoning in children and adolescents.

Laws mandating coprescription of naloxone and their impact on naloxone prescription in five US states, 2014-2018.
Researchers sought to examine early impacts of laws that require naloxone to be prescribed to patients at increased overdose risk. Data from CVS Pharmacy 90 days before and after the naloxone-prescribing mandates took effect in Arizona, Florida, Rhode Island, Vermont, and Virginia were examined. The researchers concluded that mandating the prescribing of naloxone quickly expands access to this life-saving medication for more people in more places. They recommended that other states consider mandating the co-prescription of naloxone to individuals at increased risk of overdose.

Reducing high-dose opioid prescribing: state-level morphine equivalent daily dose policies, 2007-2017.
This paper looked at current state-level policies in the United States from January 2007-May 2017 limiting high morphine equivalent daily dose (MEDD) prescribing. State-level threshold policies were reviewed using LexisNexis and Westlaw Next for legislative acts and Google for nonlegislative state-level policies. State websites were also reviewed to identify additional policies. Policies were then independently double-coded on the categories: state, agency/organization, policy type, effective date, threshold level, and policy exceptions. Currently 22 states have at least 1 MEDD policy, most commonly guidelines (14 states). Other states have prior authorizations (4 states), rules/regulations (4 states), legislative acts (3 states), claim denials (2 states), and alert systems/automatic patient reports (2 states). Thresholds vary widely (30-300 mg MEDD), with higher thresholds corresponding to more restrictive policies (claim denial), and lower thresholds corresponding to less restrictive policies (guidelines). The majority of policies exclude patients with terminal illnesses or acute pain.

With a little help from my friends: the effects of good samaritan and naloxone access laws on opioid-related deaths.
This study examined the effect of good Samaritan and naxolone access laws (NALs) on opioid-related mortality. Most states have adopted these laws, and the early adopters had the most negative association between NALs and overdose deaths. There was a negative but not statistically significant effect on opioid-related deaths for states with Good Samaritan laws.

Opioid prescriptions in older Medicare beneficiaries after the 2014 federal rescheduling of hydrocodone products.
The authors sought to examine how an October 2014 Drug Enforcement Administration policy reclassified hydrocodone product from schedule III to II has affected older adults. They found that the 2014 change in hydrocodone from schedule III to schedule II was associated with modest decreases in rates of opioid use in the elderly. They also found an unexpected increase in opioid-related hospitalizations without documented opioid prescriptions, which may represent an increase in illegal use.

Social stigma toward persons with prescription opioid use disorder: associations with public support for punitive and public health-oriented policies.
This study examined social stigma toward individuals with prescription opioid use disorder and tested whether stigma was associated with support for various policy interventions. Respondents expressed high levels of stigma toward individuals with prescription opioid use disorder. Higher levels of stigma were associated with greater support for punitive policies and lower support for public health-oriented policies.

A randomized trial testing the effect of narrative vignettes versus guideline summaries on provider response to a professional organization clinical policy for safe opioid prescribing.
The authors compared whether narrative vignettes embedded in the American College of Emergency Physicians (ACEP) daily e-newsletter improved dissemination of the clinical policy to ACEP members, and engagement of members with the clinical policy, compared with traditional summary text. They found that the vignettes outperformed traditional guideline text in promoting engagement with an evidence-based clinical guideline related to opioid prescriptions.

Opioid overdose deaths and Florida's crackdown on pill mills.
The researchers examined the effect on opioid overdose mortality of Florida state laws and law enforcement operations targeting "pill mills." They found that Florida's actions were associated with an estimated 1029 lives saved from prescription opioid overdose over a 34-month period, and estimated reductions in deaths grew over the intervention period.
