Opioid overdose prevention education for medical students: Adopting harm reduction into mandatory clerkship curricula

Abstract

Background: Opioid overdose deaths constitute a public health crisis in the United States. Strategies for reducing opioid-related harm are underutilized due in part to clinicians’ low knowledge about harm reduction theory and limited preparedness to prescribe naloxone. Educational interventions are needed to improve knowledge and attitudes about, and preparedness to address, opioid overdoses among medical students. Methods: Informed by the Department of Veterans Affairs’ Overdose Education and Naloxone Distribution (OEND) program and narrative medicine, we developed and led a mandatory workshop on harm reduction for clerkship medical students. Using validated scales, we assessed students’ knowledge and attitudes about, and preparedness to address, opioid overdoses before the workshop and 6 weeks after. Results: Of 75 participating students from February through December 2017, 55 (73%) completed pre-workshop and 38 (51%) completed both pre- and post-workshop surveys. At baseline, 40 (73%) encountered patients with perceived at-risk opioid use in the previous 6 weeks, but only 11 (20%) recalled their teams prescribing naloxone for overdose prevention. Among those completing both surveys, knowledge about and preparedness to prevent overdose showed large improvement (Cohen’s d?=?0.85, P?<?.001; Cohen’s d?=?1.24, P?<?.001, respectively) and attitudes showed moderate improvement (Cohen’s d?=?0.32, P = .04). Discussion: Educational interventions grounded in harm reduction theory can increase students’ knowledge and attitudes about, and preparedness to address, opioid overdoses.     

Targeting community-based naloxone distribution using opioid overdose death rates: A descriptive analysis of naloxone rescue kits and opioid overdose deaths in Massachusetts and Rhode Island

BackgroundRates of fatal opioid overdose in Massachusetts (MA) and Rhode Island (RI) far exceed the national average. Community-based opioid education and naloxone distribution (OEND) programs are effective public health interventions to prevent overdose deaths. We compared naloxone distribution and opioid overdose death rates in MA and RI to identify priority communities for expanded OEND.MethodsWe compared spatial patterns of opioid overdose fatalities and naloxone distribution through OEND programs in MA and RI during 2016 to 2019 using public health department data. The county-level ratio of naloxone kits distributed through OEND programs per opioid overdose death was estimated and mapped to identify potential gaps in naloxone availability across geographic regions and over time.ResultsFrom 2016 to 2019, the statewide community-based naloxone distribution to opioid overdose death ratio improved in both states, although more rapidly in RI (from 11.8 in 2016 to 35.6 in 2019) than in MA (from 12.3 to 17.2), driven primarily by elevated and increasing rates of naloxone distribution in RI. We identified some urban/non-urban differences, with higher naloxone distribution relative to opioid overdose deaths in more urban counties, and we observed some counties with high rates of overdose deaths but low rates of naloxone kits distributed through OEND programs.ConclusionsWe identified variations in spatial patterns of opioid overdose fatalities and naloxone availability, and these disparities appeared to be widening in some areas over time. Data on the spatial distribution of naloxone distribution and opioid overdose deaths can inform targeted, community-based naloxone distribution strategies that optimize resources to prevent opioid overdose fatalities.     

Implementing peer recovery services for overdose prevention in Rhode Island: An examination of two outreach-based approaches

BackgroundRhode Island has the tenth highest rate of accidental drug overdose deaths in the United States. In response to this crisis, Anchor Recovery Center, a community-based peer recovery program, developed programs deploying certified Peer Recovery Specialists to emergency departments (AnchorED) and communities with high rates of accidental opioid overdoses (AnchorMORE).ObjectivesThe purpose of this paper is to describe AnchorED and AnchorMORE's activities and implementation process.MethodsAnchorED data were analyzed from a standard enrollment questionnaire that includes participant contact information, demographics, and a needs assessment. The AnchorED program outcomes include number of clients enrolled, number of naloxone training sessions, and number of referrals to recovery and treatment services. Overdose deaths and naloxone distribution through AnchorMORE were mapped using Tableau software.ResultsFrom July 2016–June 2017, AnchorED had 1329 contacts with patients visiting an emergency department for reported substance misuse cases or suspected overdose. Among the contacts, 88.7% received naloxone training and 86.8% agreed to continued outreach with a Peer Recovery Specialist after their ED discharge. Of those receiving peer recovery services from the Anchor Recovery Community Center, 44.7% (n = 1055/2362) were referred from an AnchorED contact. From July 2016–June 2017, AnchorMORE distributed 854 naloxone kits in high-risk communities and provided 1311 service referrals.ConclusionThese findings indicate the potential impact peer recovery programs may have on engaging high-risk populations in treatment, overdose prevention, and other harm reduction activities. Additional research is needed to evaluate the reach of implementation and services uptake.     

Expanding the accessibility of harm reduction services in the United States: Measuring the impact of an automated harm reduction dispensing machine

BackgroundIn 2021, approximately 107,622 Americans died from drug overdose in the United States. With overdose deaths rising rapidly, it is imperative that prevention efforts focus on expanding proven, evidence-based strategies to curb overdose death rates such as targeted naloxone distribution and syringe service programs (SSPs). The COVID-19 pandemic placed additional strain on SSPs, increasing the need for programs that minimize direct contact and potential COVID-19 exposure. The purpose of this study is to evaluate the impact of an automated harm reduction dispensing machine on the local accessibility of harm reduction services.ObjectivesThe primary outcome of the study is the number of harm reduction supplies distributed to the community by the dispensing machine in its first year compared to the number of supplies distributed by the same organization in the previous year. Secondary outcomes include the countywide incidence of fatal drug overdose and human immunodeficiency virus (HIV) compared to previous years.MethodsThe machine is located outside, in the same location as a once weekly, in-person SSP. Clients register with the program over the phone with a harm reduction coordinator. Each client is connected to products and services such as naloxone, sharps containers, safer injection/smoking kits, pregnancy tests, HIV tests, substance use disorder treatment, and more.ResultsSince installation, 637 individuals registered with the program, 12% of whom had never reportedly used harm reduction services before. Within its first year of use, the machine dispensed 3360 naloxone doses and 10,155 fentanyl test strips, more than any other SSP in the county.ConclusionThe implementation of an automated harm reduction dispensing machine led to an increased accessibility of harm reduction products and services and was associated with a lower countywide incidence of unintentional overdose death and HIV. The association with decreased overdose death and HIV incidence should be further investigated to assess causality.     

Overdose education and naloxone distribution for veterans with opioid use disorder: Results from a pilot initiative

Patients with opioid use disorder are at a high risk of overdose. To minimize that risk, a program offering intranasal naloxone rescue kits was piloted at a Veterans Administration Hospital. The purpose of this study was to characterize veterans who accepted these potentially lifesaving kits. Retrospective medical chart review of 158 veterans with opioid use disorder receiving treatment on either the inpatient psychiatry detoxification units or outpatient methadone maintenance setting who were offered overdose education and naloxone rescue kits. One hundred and ten of 158 veterans (70%) accepted overdose education and naloxone rescue. Overall, they had a mean age of 39.1 years and averaged 12.7 years of opioid use. In the prior month, they averaged 14.3 days of heroin use; they used alone 48.5% of the time. They estimated an average of 2.8 accidental overdoses over their lifetimes. There were few significant differences between those who accepted and those who declined with regard to demographic and clinical variables. However, significantly higher percentages of outpatients accepted overdose education and naloxone rescue compared to inpatients (89% versus 63%, p = 0.003, Chi-square); the odds of acceptance were increased four-fold when offered to outpatients. Outpatients were nearly a decade older, with more years of opioid use (19.0 versus 11.0), but with less utilization of inpatient services in the prior year (all p < 0.05). The main finding was that 70% of veterans accepted overdose education and naloxone rescue, but significantly higher proportions of outpatients were more receptive than inpatients (89% versus 63%, p = 0.003). Efforts to increase overdose education and naloxone rescue acceptance in all settings are encouraged.     

Opiate use disorders and overdose: Medical students' experiences,satisfaction with learning,and attitudes toward community naloxone provision

IntroductionOpiate use disorder is a common condition in healthcare services in Ireland, where over 200 opiate overdose deaths occur annually. There is limited addiction medicine education at undergraduate level and medical graduates may not be adequately prepared to diagnose and manage opioid use disorders and emergency drug overdose presentations. Therefore, we examined final-year medical students' learning experiences and attitudes toward opioid use disorder, overdose and community naloxone provision as an emerging overdose treatment.MethodsWe administered an anonymous paper-based survey to 243 undergraduate medical students undertaking their final professional completion module prior to graduation from University College Dublin, Ireland. Results were compared with parallel surveys of General Practitioners (GPs) and GP trainees.ResultsA total of 197 (82.1%) completed the survey. Just under half were male, and most were aged under 25 (63.3%) and of Irish nationality (76.7%). The students felt moderately prepared to recognise opioid use disorder, but felt less prepared to manage other aspects of its care. Most had taken a history from a patient with an opioid use disorder (82.8%), and a third had witnessed at least one opioid overdose. Although 10.3% had seen naloxone administered, most had never administered naloxone themselves (98.5%). Half supported wider naloxone availability; this was lower than support rates among GPs (63.6%) and GP trainees (66.1%).ConclusionsOur findings suggest an unmet learning need in undergraduate training on opioid use disorder, with potential consequences for patient care.     

Legacies of the war on drugs: Next of kin of persons who died of opioid overdose and harm reduction interventions in Philadelphia

BackgroundBetween the years 2017–2019 in Philadelphia, more than 70% of all deaths from opioid overdose occurred in a private residence. To learn more about home-based opioid use and overdose, researchers conducted qualitative interviews with next of kin of overdose victims to learn their perceptions about the decedent's drug use and their opinions about city-led harm reduction efforts, specifically naloxone administration and collaborative efforts to open an overdose prevention site.MethodsIn 2019, researchers conducted 35 qualitative interviews with next of kin of persons who died of opioid overdose in Philadelphia in 2017. Data were coded and analyzed using NVivo software.ResultsData reveal that while persons who use drugs may benefit from enhanced harm reduction interventions that target their family members and caregivers including naloxone education and public health messaging about overdose prevention, these efforts may be up against other realities that Philadelphia families navigate—in particular structural inequalities exacerbated by decades of “War on Drugs” policies.ConclusionExisting health disparities and structural barriers to care increase vulnerability to overdose and highlight the urgency to collaborate with impacted families and communities to design relevant harm reduction interventions. Without efforts to redress the consequences of war on drug policies, however, harm reduction interventions will not reach their full potential.     

Non-fatal opioid overdose,naloxone access,and naloxone training among people who recently used opioids or received opioid agonist treatment in Australia: The ETHOS Engage study

BackgroundOverdose is a major cause of morbidity and mortality among people who use opioids. Naloxone can reverse opioid overdoses and can be distributed and administered with minimal training. People with experience of overdose are a key population to target for overdose prevention strategies. This study aims to understand if factors associated with recent non-fatal opioid overdose are the same as factors associated with naloxone access and naloxone training in people who recently used opioids or received opioid agonist treatment (OAT).MethodsETHOS Engage is an observational study of people who inject drugs in Australia. Logistic regression models were used to estimate odds ratios for non-fatal opioid overdose, naloxone access and naloxone training.ResultsBetween May 2018-September 2019, 1280 participants who recently used opioids or received OAT were enrolled (62% aged >40 years; 35% female, 80% receiving OAT, 62% injected drugs in the preceding month). Recent opioid overdose (preceding 12 months) was reported by 7% of participants, lifetime naloxone access by 17%, and lifetime naloxone training by 14%. Compared to people receiving OAT with no additional opioid use, recent opioid, benzodiazepine (preceding six months), and hazardous alcohol use was associated with recent opioid overdose (aOR 3.91; 95%CI: 1.68–9.10) and lifetime naloxone access (aOR 2.12; 95%CI 1.29–3.48). Among 91 people who reported recent overdose, 65% had never received take-home naloxone or naloxone training.ConclusionsAmong people recently using opioids or receiving OAT, benzodiazepine and hazardous alcohol use is associated with non-fatal opioid overdose. Not all factors associated with non-fatal overdose correspond to factors associated with naloxone access. Naloxone access and training is low across all groups. Additional interventions are needed to scale up naloxone provision.     

A novel naloxone training compared with current recommended training in an overdose simulation

ObjectivesThe aim of this study was to determine if a novel naloxone training program with a focus on situational stress management yields better results than the currently recommended state training in a simulated overdose response.MethodsStudents were randomized to receive either the state training or a novel training developed by the Wilkes University Nesbitt School of Pharmacy. After their respective training, each student individually completed a live simulated overdose response with an added stressor of a panicked bystander. A checklist was used to evaluate students during the simulation, and the results were compared.ResultsThe average grade for the novel training students was 89% compared with 64% for the state training students (P < 0.001). There was no statistically significant difference in time to complete the simulation.ConclusionStudents who underwent the novel training received the state training. The novel training appears to be effective in preparing students to manage a live opioid overdose.     

Naloxone access for Emergency Medical Technicians: An evaluation of a training program in rural communities

IntroductionOpioid-related overdose death rates in rural communities in the United States are much higher than their urban counterparts. However, basic life support (BLS) personnel, who are more common in rural areas, have much lower rates of naloxone administration than other levels of emergency medical services (EMS). Training and equipping basic level Emergency Medical Technician (EMTs) to administer naloxone for an opioid overdose could yield positive outcomes.MethodsFollowing a legislative change that allowed EMTs to administer naloxone in one rural state, we evaluated an EMT training program by examining EMTs' opioid overdose knowledge and attitudes before and after the training.ResultsOne-hundred-seventeen rural EMTs participated the training. They demonstrated statistically significant improvements on almost all of the knowledge questions after the training (p's = 0.0469 to <0.0001). The opioid overdose competency and concern scales showed statistically significant improvement (p < 0.0001) and reduction (p < 0.0001), respectively. Furthermore, statistically significant changes in knowledge and opinions of state law regarding naloxone administration were observed. Significantly more EMTs supported the idea of expanding naloxone to people at risk for overdose (p = 0.0026) after the training.ConclusionsAt a time when states are passing legislation to expand first responders' access to naloxone, this study provides evidence about authorizing EMTs to administer naloxone.     

The role of take-home naloxone in the epidemic of opioid overdose involving illicitly manufactured fentanyl and its analogs

Introduction: There has been an exponential increase in overdose fatalities as illicitly manufactured fentanyl and its analogs (IMF) are becoming more prevalent in the illicit drug supply. In response, overdose education and naloxone distribution (OEND) programs have been implemented throughout the United States as a harm reduction strategy. However, there are increasing reports that higher naloxone doses or repeat administration might be required for overdose victims involving IMF.

Areas covered: In this article, we provide a comprehensive review of the epidemiology, public health impact, and pharmacologic properties of IMF. The pharmacokinetic properties of currently available take-home naloxone (THN) kits, the role of THN as a harm reduction strategy and available data on its clinical use are discussed. Implications of occupational IMF exposure for first responders are also described.

Expert opinion: THN administration by a bystander is an effective harm reduction intervention. However, there is growing evidence that higher dose or multiple administrations of naloxone are required to fully reverse IMF related toxicity. Recently, the US Food and Drug Administration approved THN kits with a concentrated naloxone dose that produce high bioavailability. However, limited presence of OEND programs and cost of these new devices impede their accessibility to the general public.     

Opioid overdose reversals using naloxone in New York City by people who use opioids: Implications for public health and overdose harm reduction approaches from a qualitative study

BackgroundAdverse reactions to naloxone, such as withdrawal symptoms and aggression, are widely recognised in the literature by pharmaceutical manufacturers and clinical practitioners as standard reactions of individuals who are physically dependent upon opioid drugs following the reversal of potentially fatal opioid overdose. This paper seeks to provide a differentiated view on reactions to naloxone that may have important implications for public health and harm reduction approaches.MethodsAnalyses from a qualitative investigation embedded within a 5-year Randomised Controlled Trial (RCT) examined the risks and benefits of Overdose Education and Naloxone Distribution (OEND) training models (brief or extended training) in various populations of people who use opioids in New York City. The qualitative experiences (obtained through semi-structured interviews) of 46 people who use opioids and who were each involved in the delivery of naloxone, during 56 separate overdose events that occurred throughout 2016–2018, were studied. Situational analysis and inductive content analysis of interview data focused upon overdose reversals in an attempt to provide understandings of the various adverse effects associated with naloxone from their perspective. These analyses were supplemented by data sessions within the research team during which the findings obtained from situational analysis and inductive content analysis were reviewed and complemented by deductive (clinical) appraisals of the various physical and psychological effects associated with the overdose reversals.ResultsPeople who use opioids recognise three distinct and interconnected outcomes that may follow a successful opioid overdose reversal after intramuscular or intranasal administration of naloxone. These outcomes are here termed, (i) ‘rage’ (describing a wide range of angry, hostile and/or aggressive outbursts), (ii) ‘withdrawal symptoms,’ and (iii) ‘not rage, not withdrawal’ (i.e., a wide range of short-lived, ‘harmless’ conditions (such as temporary amnesia, mild emotional outbursts, or physical discomfort) that do not include rage or withdrawal symptoms).ConclusionPhysical and psychological reactions to naloxone should not be understood exclusively as a consequence of acute, opioid-related, withdrawal symptoms. The three distinct and interconnected reversal outcomes identified in this study are considered from a harm reduction policy perspective and are further framed by concepts associated with ‘mediated toxicity’ (i.e., harm triggered by medicine). The overall conclusion is that harm reduction training programmes that are aligned to the policy and practice of take home naloxone may be strengthened by including awareness and training in how to best respond to ‘rage’ associated with overdose reversal following naloxone administration by people who use opioids and other laypersons.     

Brief overdose education can significantly increase accurate recognition of opioid overdose among heroin users

BackgroundIn an effort to increase effective intervention following opioid overdose, the New York State Department of Health (NYSDOH) has implemented programs where bystanders are given brief education in recognizing the signs of opioid overdose and how to provide intervention, including the use of naloxone. The current study sought to assess the ability of NYSDOH training to increase accurate identification of opioid and non-opioid overdose, and naloxone use among heroin users.MethodsEighty-four participants completed a test on overdose knowledge comprised of 16 putative overdose scenarios. Forty-four individuals completed the questionnaire immediately prior to and following standard overdose prevention training. A control group (n = 40), who opted out of training, completed the questionnaire just once.ResultsOverdose training significantly increased participants’ ability to accurately identify opioid overdose (p < 0.05), and scenarios where naloxone administration was indicated (p < 0.05). Training did not alter recognition of non-opioid overdose or non-overdose situations where naloxone should not be administered.ConclusionsThe data indicate that overdose prevention training improves participants’ knowledge of opioid overdose and naloxone use, but naloxone may be administered in some situations where it is not warranted. Training curriculum could be improved by teaching individuals to recognize symptoms of non-opioid drug over-intoxication.
