Sustainability planning in the US response to the opioid crisis: An examination using expert and text mining approaches

Statewide efforts to address the opioid epidemic: Results from a national survey of single state agencies

BACKGROUND

Single State Agencies (SSAs) are at the forefront of efforts to address the nation's opioid epidemic, responsible for allocating billions of dollars in federal, state, and local funds to ensure service quality, promote best practices, and expand access to care. Federal expenditures to SSAs have more than tripled since the early years of the epidemic, yet, it is unclear what initiatives SSAs have undertaken to address the crisis and how they are financing these efforts.

METHODS

This study used data from an internet-based survey of SSAs, conducted by the University of Chicago Survey Lab from January to December 2021 (response rate of 94 %). The survey included a set of 14 items identifying statewide efforts to address the opioid epidemic and six funding sources. We calculated the percentage of SSAs that supported each statewide effort and the percentage of SSAs reporting use of each source of funding across the 14 statewide efforts.

RESULTS

Treatment of opioid-related overdose figured most prominently among statewide efforts, with all SSAs providing funding for naloxone distribution and all but one SSA supporting naloxone training. Recovery support services, Project ECHO, and Hub and Spoke models were supported by the vast majority of SSAs. Statewide efforts related to expanding access to medications for opioid use disorder (MOUD) received somewhat less support, with 45 % of SSAs supporting mobile methadone/MOUD clinics/programs and 70 % supporting buprenorphine in emergency departments. A relatively low proportion of SSAs (54 %) provided support for syringe services programs. State Opioid Response (SOR) funds were the most common funding source reported by SSAs (57 % of SSAs), followed by block grant funds (19 %) and other state funding (15 %).

CONCLUSION

Results highlight a range of SSA efforts to address the nation's opioid epidemic. Limited adoption of efforts to expand access to MOUD and harm reduction services may represent missed opportunities. The uncertainty over reauthorization of the SOR grant post-2025 also raises concerns over sustainability of funding for many of these statewide initiatives.

State Funding For Substance Use Disorder Treatment Declined In The Wake Of Medicaid Expansion

The US continues to grapple with an escalating epidemic of opioid-related overdose and mortality. State funds, which are the second-largest source of public funding for substance use disorder (SUD) treatment and prevention, play a critically important role in responding to this crisis. Despite their importance, little is known about how these funds are allocated and how they have changed over time, particularly within the context of Medicaid expansion. In this study we assessed trends in state funds during the period 2010-19, using difference-in-differences regression and event history models. Our findings reveal dramatic variation in state funding across states, from a low of $0.61 per capita in Arizona to a high of $51.11 per capita in Wyoming in 2019. Moreover, state funding declined during the period after Medicaid expansion by an average of $9.95 million in expansion states (relative to nonexpansion states), especially in states that expanded eligibility under Republican-controlled legislatures, where it declined by an average of $15.94 million. Medicaid substitution strategies, which, in effect, shift some of the financial burden for financing SUD treatment from the state to the federal level, may erode resources for broader system-level efforts that are urgently needed in the midst of the opioid epidemic.

Promoting sustainable responses to the US opioid epidemic with community-academic partnerships: qualitative outcomes from a statewide program

Background

Drug overdose deaths in the United States have continued to increase at an alarming rate. The Substance Abuse and Mental Health Services Administration (SAMHSA) distributed more than $7 billion between January 2016 and June 2020 to address the drug overdose crisis. The funds support evidence-based responses, including medications for opioid use disorder, and other prevention, treatment and recovery activities. Although the State Opioid Response (SOR) grants finance much-needed community level interventions, many of the services they support may not be sustainable, without ongoing assessment, evaluation and planning for continuation.

Methods

This paper describes a statewide effort to support local entities through SAMHSA’s SOR grants in Virginia. Community agencies across the state participated in detailed needs assessment exercises with VHEOC investigators, and developed requests for proposals (RFPs) to sustain their SOR programs. The RFPs were then distributed to prospective academic partners at the five VHEOC universities, based on the required subject matter expertise identified in the RFP. All responsive proposals were then provided to the local agencies who selected the proposal most likely to meet their needs. VHEOC investigators also conducted an inductive, three-phase content analysis approach to examine the RFPs submitted to the VHEOC to identify nominal categories of support requested of the VHEOC investigators.

Results

VHEOC Investigators received and coded 27 RFPs from ten community agencies representing four of five regions of the state. We identified six nominal categories of academic assistance with high inter-coder agreement. The six categories of support requested of the academic partners were program development and support, literature review and best practices, outreach and education, data analysis and interpretation, program evaluation, and grant writing assistance. Several RFPs requested up to three categories of support in a single project.

Conclusions

Our analysis of the requests received by the consortium identified several categories of academic support for SOR-grantees addressing the drug overdose crisis. The most common requests related to development and maintenance of supportive collaborations, which existing research has demonstrated is necessary for the long-term sustainability of SOR-funded services. In this way, the academic partners reinforced sustainable SOR-funded programs. As the state opioid response program is implemented nationally, we hope that other states will consider similar models in response to the opioid crisis.

ɑO-Conotoxin GeXIVA isomers modulate N-type calcium (CaV 2.2) channels and inwardly-rectifying potassium (GIRK) channels via GABAB receptor activation

αO-Conotoxin GeXIVA is a 28 amino acid peptide derived from the venom of the marine snail Conus generalis. The presence of four cysteine residues in the structure of GeXIVA allows it to have three different disulfide isomers, that is, the globular, ribbon or bead isomer. All three isomers are active at α9α10 nicotinic acetylcholine receptors, with the bead isomer, GeXIVA[1,2], being the most potent and exhibiting analgesic activity in animal models of neuropathic pain. The original report of GeXIVA activity failed to observe any effect of the isomers on high voltage-activated (HVA) calcium channel currents in rat dorsal root ganglion (DRG) neurons. In this study, we report, for the first time, the activity of globular GeXIVA[1,3] at G protein-coupled GABA_B receptors (GABA_B R) inhibiting HVA N-type calcium (Cav2.2) channels and reducing membrane excitability in mouse DRG neurons. The inhibition of HVA Ba²⁺ currents and neuroexcitability by GeXIVA[1,3] was partially reversed by the selective GABA_B R antagonist CGP 55845. In transfected HEK293T cells co-expressing human GABA_B R1 and R2 subunits and Cav2.2 channels, both GeXIVA[1,3] and GeXIVA[1,4] inhibited depolarization-activated Ba²⁺ currents mediated by Cav2.2 channels, whereas GeXIVA[1,2] had no effect. The effects of three cyclized GeXIVA[1,4] ribbon isomers were also tested, with cGeXIVA GAG being the most potent at human GABA_B R-coupled Cav2.2 channels. Interestingly, globular GeXIVA[1,3] also reversibly potentiated inwardly-rectifying K⁺ currents mediated by human GIRK1/2 channels co-expressed with GABA_B R in HEK293T cells. This study highlights GABA_B R as a potentially important receptor target for the activity of αO-conotoxin GeXIVA to mediate analgesia.
