One-Year Association of Drug Possession Law Change With Fatal Drug Overdose in Oregon and Washington.

Importance: Two states modified laws to remove or substantially reduce criminal penalties for any drug possession. The hypothesis was that removing criminal penalties for drug possession may reduce fatal drug overdoses due to reduced incarceration and increased calls for help at the scene of an overdose. Objective: To evaluate whether decriminalization of drug possession in Oregon and Washington was associated with changes in either direction in fatal drug overdose rates. Design, Setting, and Participants: This cohort study used a synthetic control method approach to examine whether there were changes in drug possession laws and fatal drug overdose rates in Oregon and Washington in the postpolicy period (February 1, 2021, to March 31, 2022, in Oregon and March 1, 2021, to March 31, 2022, in Washington). A counterfactual comparison group (synthetic controls) was created for Oregon and Washington, using 48 states and the District of Columbia, that did not implement similar policies during the study period (January 1, 2018, to March 31, 2022). For 2018-2021, final multiple cause-of-death data from the National Vital Statistics System (NVSS) were used. For 2022, provisional NVSS data were used. Drug overdose deaths were identified using International Statistical Classification of Diseases and Related Health Problems, 10th Revision underlying cause-of-death codes X40-X44, X60-X64, X85, and Y10-Y14. Exposures: In Oregon, Measure 110 went into effect on February 1, 2021. In Washington, the Washington Supreme Court decision in State v Blake occurred on February 25, 2021. Main Outcome: Monthly fatal drug overdose rates. Results: Following the implementation of Measure 110, absolute monthly rate differences between Oregon and its synthetic control were not statistically significant (probability = 0.26). The average rate difference post Measure 110 was 0.268 fatal drug overdoses per 100 000 state population. Following the implementation of the policy change in Washington, the absolute monthly rate differences between Washington and synthetic Washington were not statistically significant (probability = 0.06). The average rate difference post Blake was 0.112 fatal drug overdoses per 100 000 state population. Conclusions and Relevance: This study found no evidence of an association between legal changes that removed or substantially reduced criminal penalties for drug possession in Oregon and Washington and fatal drug overdose rates. Additional research could examine potential other outcomes as well as longer-term associations with fatal drug overdose overall and across racial and ethnic groups.

Low-Threshold Buprenorphine via Community Partnerships and Telemedicine-Case Reports of Expanding Access to Addiction Treatment During COVID-19.

BACKGROUND: To reduce coronavirus disease 2019 (COVID-19) spread, federal agencies eased telemedicine restrictions including audio-only appointments. These changes permitted clinicians to prescribe buprenorphine to patients with opioid use disorder (OUD) without in-person or audio/video assessment. Our clinic utilized existing community collaborations to implement protocols and extend outreach. We describe 3 patients with OUD who engaged with treatment through outreach with trusted community partners and low-threshold telemedicine. CASE PRESENTATIONS: Patient 1-a 40-year-old man with severe OUD who injected heroin and was living outside. A weekend harm reduction organization volunteer the patient previously knew used her mobile phone to facilitate an audio-only intake appointment during clinic hours. He completed outpatient buprenorphine initiation. Patient 2-a 48-year-old man with severe opioid and methamphetamine use disorders who injected both and was living in his recreational vehicle. He engaged regularly with syringe services program (SSP), but utilized no other healthcare services. Initially, an SSP worker connected him to our clinic for audio-only appointment using their landline to initiate buprenorphine; a harm reduction volunteer coordinated follow-up. Patient 3-a 66-year-old man with moderate OUD used non-prescribed pill opioids without prior buprenorphine experience. He lived over 5 hours away in a rural town. He underwent virtual appointment and completed home buprenorphine initiation. CONCLUSION: These 3 cases illustrate examples of how policy changes allowing for telemedicine buprenorphine prescribing can expand availability of addiction services for patients with OUD who were previously disengaged for reasons including geography, lack of housing, transportation difficulties, and mistrust of traditional healthcare systems.

Simulating the impact of Addiction Consult Services in the context of drug supply contamination, hospitalizations, and drug-related mortality.

BACKGROUND: Illicitly manufactured fentanyl (IMF) is increasing in international drug supply chains, and IMF-related opioid overdose deaths are rising in North America. Hospitalizations among patients with opioid use disorder (OUD) are also rising; and, hospitalized patients are at increased risk of overdose and death following hospital discharge. Hospitalization is a key opportunity to engage patients with OUD. Addiction consult services (ACS) can provide effective treatment for patients hospitalized with OUD. This study aims to estimate the effect of increasing IMF contamination on drug-related death among patients hospitalized with OUD, and simulate the role of ACS expansion to mitigate these effects. METHODS: We used a Markov model to mirror care systems for adult patients hospitalized with OUD in Oregon, from the time of hospital admission through 12-months post-discharge, and simulated patients through modeled care systems to evaluate the expansion of Addiction Consult Services in the context of increasing IMF in the drug supply. RESULTS: In a simulated cohort of 10,000 patients, we estimate that 537 patients would die from drug-related causes within 12-months of hospital discharge. In the context of increased IMF in the drug supply, this estimate increased to 913. ACS referral at baseline was 4%; increasing ACS referral to accommodate 10%, 50%, or 100% of hospitalized OUD patients in the state reduces drug-related deaths to 904, 849, and 780, respectively. The number needed to treat for ACS to avoid one drug-related death in the context of increased IMF was 73. CONCLUSIONS: Hospitals should expand interventions to help reduce IMF-related opioid overdoses, including through implementation of ACS. In the context of rising IMF-related deaths, ACS expansion could help connect patients to treatment, offer harm reduction interventions, or both, which can help reduce the risk of opioid-related death.

Low-barrier buprenorphine during the COVID-19 pandemic: A rapid transition to on-demand telemedicine with wide-ranging effects.

Low barrier addiction clinics increase access to medications to treat substance use disorders, while emphasizing harm reduction. The Harm Reduction and BRidges to Care (HRBR) Clinic is an on demand, low barrier addiction clinic that opened in October 2019. In the first three months of operation (November through January 2020), HRBR saw steadily increasing numbers of patients. Oregon saw its first case of novel coronavirus in February, and declared a state of emergency and enacted a formal "Stay at Home" order in March. That same month, the DEA announced that patients could be initiated on buprenorphine through telemedicine visits without an in-person exam. Within a week of being granted the ability to see patients virtually, HRBR had transitioned to over 90% virtual visits, while still allowing patients without technology to access in-person care. Within four weeks, the clinic expanded hours significantly, established workflows with community harm reduction partners, and was caring for patients in rural areas of the state. In response to the COVID-19 crisis, the HRBR clinic was able to quickly transition from in-person to almost completely virtual visits within a week. This rapid pivot to telemedicine significantly increased access to care for individuals seeking low-threshold treatment in multiple contexts. Overarching institutional support, grant funding and a small flexible team were critical. HRBR's increased access and capacity were only possible with the Drug Enforcement Agency loosening restrictions around the use of telehealth for new patients. Keeping these altered regulations in place will be key to improving health and health care equity for people who use drugs, even after the pandemic subsides. Further research is needed in to whether addiction telemedicine impacts medication diversion rates, continued substance use, or provider practices.

Population-based trends in hospitalizations due to injection drug use-related serious bacterial infections, Oregon, 2008 to 2018.

BACKGROUND: Injection drug use has far-reaching social, economic, and health consequences. Serious bacterial infections, including skin/soft tissue infections, osteomyelitis, bacteremia, and endocarditis, are particularly morbid and mortal consequences of injection drug use. METHODS: We conducted a population-based retrospective cohort analysis of hospitalizations among patients with a diagnosis code for substance use and a serious bacterial infection during the same hospital admission using Oregon Hospital Discharge Data. We examined trends in hospitalizations and costs of hospitalizations attributable to injection drug use-related serious bacterial infections from January 1, 2008 through December 31, 2018. RESULTS: From 2008 to 2018, Oregon hospital discharge data included 4,084,743 hospitalizations among 2,090,359 patients. During the study period, hospitalizations for injection drug use-related serious bacterial infection increased from 980 to 6,265 per year, or from 0.26% to 1.68% of all hospitalizations (P<0.001). The number of unique patients with an injection drug use-related serious bacterial infection increased from 839 to 5,055, or from 2.52% to 8.46% of all patients (P<0.001). While hospitalizations for all injection drug use-related serious bacterial infections increased over the study period, bacteremia/sepsis hospitalizations rose most rapidly with an 18-fold increase. Opioid use diagnoses accounted for the largest percentage of hospitalizations for injection drug use-related serious bacterial infections, but hospitalizations for amphetamine-type stimulant-related serious bacterial infections rose most rapidly with a 15-fold increase. People living with HIV and HCV experienced increases in hospitalizations for injection drug use-related serious bacterial infection during the study period. Overall, the total cost of hospitalizations for injection drug use-related serious bacterial infections increased from $16,305,129 in 2008 to $150,879,237 in 2018 (P<0.001). CONCLUSIONS: In Oregon, hospitalizations for injection drug use-related serious bacterial infections increased dramatically and exacted a substantial cost on the health care system from 2008 to 2018. This increase in hospitalizations represents an opportunity to initiate substance use disorder treatment and harm reduction services to improve outcomes for people who inject drugs.

Life projects: the transformative potential of direct-acting antiviral treatment for hepatitis C among people who inject drugs.

BACKGROUND AND OBJECTIVES: People who inject drugs (PWID) are disproportionately affected by chronic hepatitis C (HCV) in high-income countries. The advent of direct-acting antivirals (DAAs) makes treatment of this underserved population more possible than ever. The dearth of programs adapted to the needs of PWID and stigma associated with drug use and chronic HCV pose significant barriers to the effective uptake of treatment among this population. We employed "life projects" as a conceptual framework to examine the social incentives of PWID being treated for HCV. This study advances the existing literature on the transformative potential of HCV treatment among PWID, explores how these transformations may affect treatment success, and discusses implications for decisions around whether and when to treat PWID. METHODS: We conducted in-depth interviews with participants of a pilot clinical trial testing the effective delivery of DAA treatment to PWID within two healthcare for the homeless clinic settings - one group receiving opioid agonist therapy (OAT) and another group frequenting a needle and syringe exchange program (NSP). A purposive sample of 27 participants was selected based on place of care. Interviews were transcribed, coded, and analysed for patterns using a priori domains and emergent themes. RESULTS: Participants in both treatment groups described significant life projects that motivated them to complete HCV treatment. These projects included social redemption, strengthening of relationships, pursuit of abstinence from substance use, and harm reduction. These themes were consistent between treatment groups, though more participants in the syringe exchange group relied on harm reduction than on pursuing abstinence to prevent reinfection after achieving virologic cure. CONCLUSION: Understanding the incentives that propel PWID to complete HCV treatment could help to enhance treatment uptake and adherence through dedicated programs that address current barriers to care.
