Price Sensitivity and Information Barriers to the Take-Up of Naloxone

We conducted a field experiment that randomized advertisements, advertisement content, and prices across 2,204 counties in the United States to study the impacts on online purchases of naloxone, an opioid overdose reversal drug. Advertising increased web-site users but only impacted purchases when combined with a price reduction. Messages emphasizing the discreet nature of online sales had no additional impact on purchases. Comparing counties with advertisements featuring a highly discounted price to those featuring the full price, we estimate a price elasticity of demand for online naloxone of −1.3. Price is a significant barrier to online purchases of this lifesaving medication. (JEL C93, H75, I12, I18, L65, M37)

Genomic study in opioid-treated cancer patients identifies variants associated with nausea-vomiting

ContextOpioids are the mainstay therapy for patients affected by cancer pain. However, about 10-20% of patients do not benefit from the received analgesic treatment or experience side effects. Genetic variability might account for the variation in individual responses to opioids, both in terms of efficacy and toxicity. ObjectivesThe aim of this genome-wide association study (GWAS) was to identify genetic markers of opioid toxicity, in terms of nausea-vomiting. MethodsCancer patients receiving morphine, oxycodone, buprenorphine, and fentanyl were recruited from different European countries. Data about toxicity (nausea-vomiting score, NVS) and other relevant clinical information were collected, as well as genotyping data. Regression analysis between genotypes of 2,052 patients and NVS was performed, using appropriate covariates, with REGENIE software. ResultsWe found 65 variants associated with NVS (P-value < 1.0×10−5). Of note, 14 intronic variants on chromosome 2 were in NPAS2 gene, encoding a circadian transcription factor reported to play a role in another opioid side effect, the alteration of sleep. Some of these variants were previously identified as splicing quantitative trait loci of the NPAS2 gene. ConclusionsThis is the first GWAS, performed in more than two thousand individually genotyped patients treated with opioids for cancer pain, that investigated the genetic bases of opioid-induced nausea-vomiting. Although further studies are needed to confirm our findings and to characterize the functional role of the identified variants, our results emphasize the importance of performing large pharmacogenomic studies to identify germline variants associated with opioid response, with the ultimate goal of tailoring cancer pain therapies.

What Are Community Supervision Officers’ Knowledge and Views of Naloxone? An Exploratory Study

Naloxone is a critical component in fighting the opioid epidemic, particularly for justice-involved individuals who are at an increased risk of drug-related deaths. However, numerous barriers to carrying the medication continue to exist for individuals under community supervision. Little is known about community supervision officers’ perceptions and knowledge surrounding Naloxone, which is critical in understanding barriers to Naloxone possession for those on supervision. To address this gap in the literature, this exploratory mixed-methods study gathered data through an online survey of community supervision officers ( n = 109). The findings suggest that while Naloxone is widely known among community supervision officers, there is a need for more consistent training to improve knowledge, address stigmas/misconceptions, and further equip officers to support overdose prevention through harm reduction. Future research on this topic is crucial to help address barriers to distributing and using Naloxone to reduce opioid overdose deaths among those on community supervision.

Naloxone Coprescribing and the Prevention of Opioid Overdoses: Quasi-Experimental Metacognitive Assessment of a Novel Education Initiative.

Critical evaluation of naloxone coprescription academic detailing programs has been positive, but little research has focused on how participant thinking changes during academic detailing. The dual purposes of this study were to (1) present a metacognitive evaluation of a naloxone coprescription academic detailing intervention and (2) describe the application of a metacognitive evaluation for future medical education interventions. Data were obtained from a pre-post knowledge assessment of a web-based, self-paced intervention designed to increase knowledge of clinical and organizational best practices for the coprescription of naloxone. To assess metacognition, items were designed with confidence-weighted true-false scoring. Multiple metacognitive scores were calculated: 3 content knowledge scores and 5 confidence-weighted true-false scores. Statistical analysis examined whether there were significant differences in scores before and after intervention. Analysis of overall content knowledge showed significant improvement at posttest. There was a significant positive increase in absolute accuracy of participant confidence judgments, confidence in correct probability, and confidence in incorrect probability (all P values were <.05). Overall, results suggest an improvement in content knowledge scores after intervention and, metacognitively, suggest that individuals were more confident in their answer choices, regardless of correctness. Implications include the potential application of metacognitive evaluations to assess nuances in learner performance during academic detailing interventions and as a feedback mechanism to reinforce learning and guide curricular design.

In Case You Haven't Heard…

Now in research phases, an armband that senses opioid overdose and automatically injects naloxone is hoped to prevent deaths, which now number 100,000 a year. Naloxone must be administered almost immediately after an overdose to prevent brain damage. With almost half of opioid overdose deaths occurring when the victim is totally alone, it may be essential to move this technology forward, according to AltruMed, which is seeking federal funding for its DOVE device. It detects opioid overdose via pulse oximetry and accelerometry. A current grant is testing the harness, sensor and injector components of DOVE.

OASAS will deliver free test strips and naloxone to New Yorkers

New Yorkers can get free fentanyl test strips, xylazine test strips and/or naloxone from the state Office of Addiction Services and Supports (OASAS). These can be requested from the local Opioid Overdose Prevention Program or a pharmacy, according to OASAS, if supplies are needed immediately. For a directory of Opioid Overdose Prevention Programs, go here. Delivery will take two weeks, according to OASAS. To order the test strips and naloxone, submit a request through the website: https://forms.ny.gov/s3/Harm‐Reduction‐Order‐Form. The initiative is paid for by the Opioid Settlement Fund.

Sustainability of Treatment Programs Utilizing Medications for Opioid Use Disorders in Incarcerated Young Adults.

The epidemic of opioid overdose brought a major health crisis to the front line of public health in the United States. Early efforts have focused on the prevention of production, distribution, and consumption of the drugs. However, there is little information about youth populations at risk for opioid overdose and their response to targeted treatment plans. The San Bernardino County Youth Opioid Response (SBCYOR) coalition in collaboration with the San Bernadino County (SBC) Probation Department organized a safety net system for at-risk youth by improving communication among county resources. This program mainly focused on individuals aged 12 to 24 years in the county's detention centers along with educational and prevention projects such as naloxone programs for first responders in the region. To describe the impact of the SBCYOR program on at-risk youth, we compare the frequencies of patients referred and treated with medications for opioid use disorder (MOUD) at the SBC Probation Department, which was responsible for individuals from age 12 to less than 18 years, with those from the West Valley Detention Center (WVDC), which was responsible for adults (18 to 24 years of age), from September 2020 through June 2022. Similar proportions of youths were referred for treatment of opioid use disorder (OUD) at the respective sites (3.7% SBC Probation Department, 3.6% WVDC). Of these, however, 78.0% were treated with MOUD at SBC Probation Department compared with only 7.1% at WVDC. SBCYOR coalition partners were able to transform their services into a comprehensive medical and behavioral health program for the incarcerated youth population at risk for OUD.

Improving racial/ethnic health equity and naloxone access among people at risk for opioid overdose: A simulation modeling analysis of community-based naloxone distribution strategies in Massachusetts, United States.

During the COVID-19 pandemic, there was a surge in opioid overdose deaths (OODs) in Massachusetts, USA, particularly among Black and Hispanic/Latinx populations. Despite the increasing racial and ethnic disparities in OODs, there was no compensatory increase in naloxone distributed to these groups. We aimed to evaluate two community-based naloxone expansion strategies, with the objective of identifying approaches that could mitigate mortality and racial and ethnic disparities in OODs. Individual-based simulation model. We measured naloxone availability using naloxone kits per OOD and evaluated scenarios of achieving higher benchmarks for naloxone availability (i.e. 40, 60 and 80 kits per OOD) from 2022 levels (overall: 26.0, White: 28.8, Black: 17.3, Hispanic/Latinx: 18.9). We compared two naloxone distribution strategies: (1) proportional distribution: achieving the benchmark ratio at the overall population level while distributing additional kits proportional to the 2022 level for each racial/ethnic group (at 40 kits per OOD benchmark: overall: 40, White: 44.3, Black: 26.6, Hispanic/Latinx: 29.1), and (2) equity-focused distribution: achieving the benchmark ratio among each racial/ethnic group (at 40 kits per OOD benchmark: 40 for all groups). Massachusetts, United States. People at risk of OOD. Annual number and rate of OODs, total healthcare costs of increasing naloxone availability. Both naloxone distribution strategies yielded comparable predicted reductions in total OODs in 2025 and incurred similar incremental costs. However, the relative reduction in the rate of OODs differed across groups. For achieving an 80 kits per OOD benchmark, proportional distribution resulted in a projected 6.7%, 6.5% and 7.1% reduction in annual OODs in 2025 among White, Black and Hispanic/Latinx populations, respectively. In contrast, equity-focused distribution achieved a reduction of 5.7%, 11.3% and 10.2% in the respective groups. In all scenarios, the cost per OOD averted was lower than the generally accepted thresholds for cost per life saved. An equity-focused naloxone distribution strategy designed to reduce racial and ethnic disparities in naloxone availability could improve health equity among racial and ethnic groups while potentially improving overall population health at lower healthcare costs per opioid overdose death averted than a proportional distribution strategy.

Iterative Development of a Clinical Decision Support Tool to Enhance Naloxone Co-Prescribing.

Background Opioid overdoses have contributed significantly to mortality in the United States. Despite long-standing recommendations from the Centers for Disease Control and Prevention to co-prescribe naloxone for patients receiving opioids who are at high risk of overdose, compliance with these guidelines has remained low. Objectives The objective of this study was to develop and evaluate a hospital-wide electronic health record (EHR)-based clinical decision support (CDS) tool designed to promote naloxone co-prescription for high-risk opioids. Methods We employed an iterative approach to develop a point-of-order, interruptive EHR alert as the primary intervention and assessed naloxone prescription rates, EHR efficiency metrics, and barriers to adoption. Data was obtained from our EHR's clinical data warehouse and analyzed using statistical process control and Chi-square analyses to assess statistically significant differences in prescribing rates during the intervention periods. Results The initial implementation phase of the intervention, spanning from April 2019 to May 2022, yielded a nearly 3-fold increase in the proportion of high-risk patients receiving naloxone, rising from 13.4% [95% CI, 12.9% - 13.8%] to 36.4% [95% CI, 35.2% - 37.5%; p = 1 x 10-38]. Enhancements to the CDS design and logic during the subsequent iteration's study period, June 2022 and December 2023, reduced the number of CDS triggers by more than 30-fold while simultaneously driving an additional increase in naloxone receipt to 42.7% [95% CI, 40.6% - 44.8%; p = 2 x 10-5]. The efficiency of the CDS demonstrated marked improvement, with prescribers accepting the naloxone co-prescription recommendation provided by the CDS in 41.1% of the encounters in version two, compared to 6.2% in version one (p = 6 x 10-9). Conclusion This study offers a sustainable and scalable model to address low rates of naloxone co-prescription and may also be used to target other opportunities for improving guideline-concordant prescribing practices.

Who is fatigued? A repeated cross-sectional survey of officer attitudes towards people who use opioids, naloxone, and their role in responding to opioid overdoses

Many police departments have equipped their officers with naloxone as a promising response to the opioid crisis. Though research suggests police can effectively administer naloxone, recent studies suggest that officers may develop negative attitudes over time as they continually respond to overdoses. This has been described as a “compassion fatigue” effect. We investigate the compassion fatigue hypothesis with a repeated cross-sectional survey of officers in the Tempe, Arizona Police Department. We focus on three outcomes (1) perceptions of officers' role in responding to overdoses, (2) perceptions of naloxone related risk-compensation beliefs, and (3) stigmatizing perceptions of people who use opioids (PWUOs). We run one-way fixed effects regression models to assess if officer attitudes have changed over the study period. Then we run multivariate regression models to test whether officers' opioid overdose response frequency is associated with any of the three outcomes. The findings suggest officers have become more supportive of responding to overdoses but have developed more stigmatizing views of PWUOs over time. This warrants further research attention. However, opioid overdose response frequency was not associated with any of the outcomes. We conclude with a discussion of these findings and their implications for police involvement in the opioid overdose crisis.

Naloxone Distribution Models in the United States: A Scoping Review.

Increasing naloxone distribution is a high priority means to mitigating opioid overdose rates in the United States. Since a variety of naloxone distribution models exist, with differences in infrastructure and funding between states and health-systems, it is important to review their differences and understand the strengths and barriers to widespread implementation of each model. The following 4 databases were searched for articles reporting on naloxone distribution models: (1) PubMed/Medline (National Library of Medicine), (2) Embase (Elsevier), (3) Scopus (Elsevier), and (4) the Cochrane library. Reports from all years written in English that discussed naloxone distribution models in the United States were included, as were all study designs. Of 5825 articles initially identified, 173 were selected for full text review. Of these, 49 met full criteria and were included for data extraction and analysis. Most distribution models occurred in community-based opioid education and naloxone distribution programs and in community pharmacies via a standing order/statewide protocol. Most programs reported strengths related to feasibility, but frequently reported cost as a limitation. Fewer studies described distribution models in ambulatory care or hospital settings, though these studies also highlighted strengths related to feasibility, particularly with support from working partners, and when utilizing an interprofessional care approach. Few studies reported health/economic outcomes data associated with naloxone distribution, such as changes in the number of patient/layperson access, the number of opioid overdose reversals, or cost-savings. This review outlines the many ways in which naloxone is distributed in the United States and emphasizes a need for improved outcomes data collecting/reporting in the various settings where naloxone is distributed. This would allow for future studies to evaluate which distribution model factors are associated with improvements in health outcomes, such as increased layperson access, and lower opioid overdose/mortality rates.

A Fentanyl Hapten‐Displaying Lipid Nanoparticle Vaccine that Non‐Covalently Encapsulates a TLR7/8 Agonist and T‐helper Epitope Induces Protective Anti‐Fentanyl Immunity

Opioid use disorder ‐ particularly involving fentanyl ‐ has precipitated a public health crisis characterized by a significant increase in addiction and overdose‐related deaths. Fentanyl‐specific immunotherapy, which aims at inducing fentanyl‐specific antibodies capable of binding fentanyl molecules in the bloodstream, preventing their entry in the central nervous system, is therefore gaining momentum. Conventional opioid designs rely on the covalent conjugation of fentanyl analogues to immunogenic carrier proteins that hold the inherent capacity of mounting immunodominant responses. Here, we present an alternative fentanyl vaccine design that utilizes a non‐covalent assembly of lipid nanoparticles (LNPs) to deliver fentanyl haptens in conjunction with a CD4+ T‐helper peptide epitope and an imidazoquinoline TLR7/8 agonist. Our results demonstrate that a single intramuscular administration of the LNP‐based nanovaccine elicits fentanyl‐specific antibodies, significantly mitigating the effects of opioid overdose in preclinical mouse models. Furthermore, we analyzed the immunobiological behavior of the vaccine in vivo in mouse models, providing evidence that covalent attachment of a fentanyl hapten to a carrier proteins or peptide epitope is not necessary for inducing an effective immune response. However, co‐delivery ‐ specifically, the physical assembly of all immune cues into an LNP ‐ remains essential for inducing hapten‐specific immunity.

The Lookout Project: A Student-Run Mail-Based Overdose Response Kit Distribution Program Through Social Media During COVID-19.

Naloxone distribution and overdose education are key preventive strategies to reduce opioid overdose deaths. This paper describes the development and evaluation of The Lookout Project (TLP), a 501(c)(3) organization led by college students and based in Ann Arbor, Michigan. This research aimed to examine the outreach of TLP with hopes of creating a reproducible mail-based kit distribution program for college student-run organizations to replicate. TLP used a targeted social media advertising campaign to ask participants 7 multiple-choice questions concerning their demographics, previous incarcerations, experiences with intranasal naloxone (IN), and if they had watched the optional informational video in the opioid overdose response kit (OORK) order form. TLP's team distributed over 900 OORKs from August 3, 2020, to January 4, 2022, first by word of mouth and then through social media advertising that began on February 13, 2021. Of the 657 respondents who agreed to participate in research, the majority identified as white (76.0%, n = 400), did not identify with any specified ethnicity group (60.2%, n = 318), were female (60.8%, n = 356), were between the ages of 18 and 22 (35.4%, n = 209), had not been previously incarcerated (95.6%, n = 564), and did watch the hyperlinked video detailing how to respond to an overdose (74.7%, n = 438). Additionally, several kit recipients (2.8%, n = 19) responded to a follow-up survey. Of those, 7 people reported using the IN provided by TLP to reverse an overdose (36.8%, n = 7). TLP, a nonprofit organization founded by college students, shows potential for informing other student-run organizations about naloxone distribution programs using social media advertising.

Slow dissociation kinetics of fentanyls and nitazenes correlates with reduced sensitivity to naloxone reversal at the μ-opioid receptor.

Fentanyls and nitazenes are μ-opioid receptor agonists responsible for a large number of opioid overdose deaths. Here, we determined the potency, dissociation kinetics and antagonism by naloxone at the μ receptor of several fentanyl and nitazene analogues, compared to morphine and DAMGO. In vitro assays of G protein activation and signalling and arrestin recruitment were performed. AtT20 cells expressing μ receptors were loaded with a membrane potential dye and changes in fluorescence used to determine agonist potency, dissociation kinetics and susceptibility to antagonism by naloxone. BRET experiments were undertaken in HEK293T cells expressing μ receptors to assess Gi protein activation and β-arrestin 2 recruitment. The apparent rate of agonist dissociation from the μ receptor varied: morphine, DAMGO, alfentanil and fentanyl dissociated rapidly, whereas isotonitazene, etonitazene, ohmefentanyl and carfentanil dissociated slowly. Slowly dissociating agonists were more resistant to antagonism by naloxone. For carfentanil, the slow apparent rate of dissociation was not because of G protein receptor kinase-mediated arrestin recruitment as its apparent rate of dissociation was not increased by inhibition of G protein-coupled receptor kinases (GRKs) with Compound 101. The in vitro relative potencies of fentanyls and nitazenes compared to morphine were much lower than that previously observed in in vivo experiments. With fentanyls and nitazenes that slowly dissociate from the μ receptor, antagonism by naloxone is pseudo-competitive. In overdoses involving fentanyls and nitazenes, higher doses of naloxone may be required for reversal than those normally used to reverse heroin overdose.

Law enforcement officer perceptions of the Good Samaritan law and their role in the opioid epidemic in the United States

PurposeGood Samaritan laws were enacted to reduce overdose deaths by lowering the barriers to reporting for victims and witnesses and allowing law enforcement officers to carry and administer Narcan to those suspected of an opioid-related overdose The purpose of this study is to understand how officers perceive the impact of opioid overdose reduction initiatives in the United States and their role in the opioid epidemic.Design/methodology/approachMixed methods were used in two phases to examine perceptions among law enforcement officers in a Massachusetts police department. First, qualitative methods were used to interview nine patrol officers during participant observations in the form of ride-alongs. Second, patrol officers and officers who volunteer with the department opioid outreach program were surveyed.FindingsOfficers generally held mixed feelings about the state’s Good Samaritan law. They saw the importance of saving the lives of those experiencing an overdose and keeping other first responders safe, but also in enforcing laws against possession of illegal drugs that presents a public safety threat, including the accidental exposure to fentanyl. Despite mixed feelings, officers still believed it to be important that they are trained and able to administer Narcan since they are often the first to arrive on scene.Originality/valueThis study adds to the research on officers’ perceptions of their role in the opioid epidemic, their ability to administer Narcan and the impact of Good Samaritan laws on their community.

Risk of Opioid Overdose Associated with Concomitant Use of Methadone and Statins.

Methadone has a high potential for risky drug-drug interactions that can lead to opioid overdose, yet evidence on the magnitude of this risk remains limited. Since methadone is transported via P-glycoprotein (P-gp), the use of statins that inhibit P-gp may elevate methadone plasma concentrations, potentially leading to opioid overdose. We explored this hypothesis by examining whether concomitant use of methadone and P-gp-inhibiting statins was associated with opioid overdose. Using Medicaid claims data from 2003 to 2020, we conducted a cohort study among new concomitant users of methadone and statins. We compared overdose rates among individuals exposed to P-gp-inhibiting statins (simvastatin, atorvastatin, or lovastatin) vs. those exposed to rosuvastatin (negative control), adjusting for baseline covariates. We identified 69,263 individuals newly exposed to methadone and a statin of interest; the overall incidence rate of opioid overdose was 26.0 per 1,000 person-years. Adjusted hazard ratios (HRs) for methadone + P-gp-inhibiting statins consistently showed no association, ranging from 0.76 (95% CI = 0.48-1.22) for atorvastatin to 0.78 (95% CI = 0.50-1.22) for simvastatin, compared with methadone + rosuvastatin. Similar results were observed in sensitivity analysis that treated all P-gp-inhibiting statins as a single exposure group, as well as analyses stratified by baseline diagnosis of opioid use disorder or overdose, the duration of baseline methadone use, and calendar year intervals. Our findings suggest that concomitant use of methadone with simvastatin, atorvastatin, or lovastatin is not associated with the risk of opioid overdose compared to concomitant use of methadone and rosuvastatin.

Communities That HEAL Intervention and Mortality Including Polysubstance Overdose Deaths

The HEALing Communities Study (HCS) evaluated the effectiveness of the Communities That HEAL (CTH) intervention in preventing fatal overdoses amidst the US opioid epidemic. To evaluate the impact of the CTH intervention on total drug overdose deaths and overdose deaths involving combinations of opioids with psychostimulants or benzodiazepines. This randomized clinical trial was a parallel-arm, multisite, community-randomized, open, and waitlisted controlled comparison trial of communities in 4 US states between 2020 and 2023. Eligible communities were those reporting high opioid overdose fatality rates in Kentucky, Massachusetts, New York, and Ohio. Covariate constrained randomization stratified by state allocated communities to the intervention or control group. Trial groups were balanced by urban or rural classification, 2016-2017 fatal opioid overdose rate, and community population. Data analysis was completed by December 2023. Increased overdose education and naloxone distribution, treatment with medications for opioid use disorder, safer opioid prescribing practices, and communication campaigns to mitigate stigma and drive demand for evidence-based interventions. The primary outcome was the number of drug overdose deaths among adults (aged 18 years or older), with secondary outcomes of overdose deaths involving specific opioid-involved drug combinations from death certificates. Rates of overdose deaths per 100 000 adult community residents in intervention and control communities from July 2021 to June 2022 were compared with analyses performed in 2023. In 67 participating communities (34 in the intervention group, 33 in the control group) and including 8 211 506 participants (4 251 903 female [51.8%]; 1 273 394 Black [15.5%], 603 983 Hispanic [7.4%], 5 979 602 White [72.8%], 354 527 other [4.3%]), the average rate of overdose deaths involving all substances was 57.6 per 100 000 population in the intervention group and 61.2 per 100 000 population in the control group. This was not a statistically significant difference (adjusted rate ratio [aRR], 0.92; 95% CI, 0.78-1.07; P = .26). There was a statistically significant 37% reduction (aRR, 0.63; 95% CI, 0.44-0.91; P = .02) in death rates involving an opioid and psychostimulants (other than cocaine), and nonsignificant reductions in overdose deaths for an opioid with cocaine (6%) and an opioid with benzodiazepine (1%). In this clinical trial of the CTH intervention, death rates involving an opioid and noncocaine psychostimulant were reduced; total deaths did not differ statistically. Community-focused data-driven interventions that scale up evidence-based practices with communications campaigns may effectively reduce some opioid-involved polysubstance overdose deaths.

Socio-demographic, clinical variables and pain among Egyptian patients of opioid use disorder with and without comorbid gabapentin use

IntroductionThere is increased clinical use of gabapentin, these trends appear to chronologically align with the opioid overdose crisis and particularly with the increased restrictions on opioid prescription.ObjectivesThe study aimed to assess the clinical variables, pain quality, and severity among patients with opioid use disorder as the main substance with and without gabapentin comorbid use.MethodsThe research involved 60 patients diagnosed with substance use disorder, divided into two groups: opioid use as the main substance and opioid use with comorbid gabapentin. All participants were assessed using a semi-structured clinical addiction interview, the structured clinical interview for diagnostic and statistical manual of mental disorders, the Addiction Severity Index, urine drug test, McGill Pain Questionnaire, and Douleur Neuropathique en 4 Questionnaire, in one interview setting.ResultsThe study showed that pain relief was the main desirable effect in the gabapentin group, with 66.2% of the group experiencing it. Euphoria was the desirable effect in the opioid group, while overdose was more common in the gabapentin group. Respiratory complications were also more common in the Gabapentin group.ConclusionThe study concluded that patients with comorbid gabapentin use disorder had a higher frequency of overdose, history of pain, and significant neuropathic pain, while less abstinence.
