Opioid overdose prevention training with naloxone,an adjunct to basic life support training for first-year medical students

ABSTRACT

Background: Opioid overdose deaths have reached epidemic proportions in the United States. This problem stems from both licit and illicit opioid use. Prescribing opioids, recognizing risky use, and initiating prevention, including opioid overdose prevention training (OOPT), are key roles physicians play. The American Heart Association (AHA) modified their basic life support (BLS) algorithms to consider naloxone in high-risk populations and when a pulse is appreciated; however, the AHA did not provide OOPT. The authors' intervention filled this training deficiency by teaching medical students opioid overdose resuscitation with a Train-the-Trainer model as part of mandatory BLS training. Methods: The authors introduced OOPT, following a Train-the-Trainer model, into the required basic life support (BLS) training for first-year medical students at a single medical school in a large urban area. The authors administered pre- and post-evaluations to assess the effects of the training on opioid overdose knowledge, self-reported preparedness to respond to opioid overdoses, and attitudes towards patients with substance use disorders (SUDs). Results: In the fall 2014, 120 first-year medical students received OOPT. Seventy-three students completed both pre- and posttraining evaluations. Improvements in knowledge about and preparedness to respond to opioid overdoses were statistically significant (P < .01) and large (Cohen's D = 2.70 and Cohen's D = 2.10, respectively). There was no statistically significant change in attitudes toward patients with SUDs. Conclusions: The authors demonstrated the effectiveness of OOPT as an adjunct to BLS in increasing knowledge about and preparedness to respond to opioid overdoses; improving attitudes toward patients with SUDs likely requires additional intervention. The authors will characterize knowledge and preparedness durability, program sustainability, and long-term changes in attitudes in future evaluations. These results support dissemination of OOPT as a part of BLS training for all medical students, and potentially all BLS providers.     

Lowering barriers to naloxone access through a student-led harm reduction program

BackgroundIn recent years, the opioid crisis has had devastating effects on communities across the country. In the wake of 4 University of Southern California (USC) student overdose deaths in 2019, USC pharmacy students initiated a naloxone distribution program called NaloxoneSC. This program has distributed free naloxone kits, fentanyl test strips, and overdose prevention training to hundreds of students thus far. This report aims to provide a framework for the implementation of similar harm reduction programs at other universities.ObjectivesNaloxoneSC partnered with USC Student Health to implement a naloxone distribution program that expands access to naloxone and increases opioid overdose education within the USC community.SettingUSC undergraduate campus and Health Sciences Campus.MethodsStudents can follow the steps for obtaining a naloxone kit listed on the NaloxoneSC website. Watching a 10-minute training video or attending a naloxone training workshop completes the opioid overdose education. The kit is picked up by the student from 1 of 2 USC Student Health Center locations, Engemann or Eric Cohen. Each kit is packaged with Narcan nasal spray and fentanyl test strips.ResultsIn 1 year, the program received at least 320 naloxone kit requests. Demand for naloxone kits increased over time, and roughly 4 times as many students requested kits from Engemann than from Eric Cohen. Approximately 600 students have received opioid overdose education through NaloxoneSC.ConclusionsIn 1 year, more than 300 USC students voluntarily requested naloxone kits from NaloxoneSC. These findings suggest a need for increased access to this resource on college campuses. Peer-to-peer education and naloxone kit distribution are feasible and effective strategies that help address public health concerns and reduce harm among university students. NaloxoneSC can serve as an example for other college campuses or entities to newly implement or expand their own harm reduction measures.     

Amount of naloxone used to reverse opioid overdoses outside of medical practice in a city with increasing illicitly manufactured fentanyl in illicit drug supply

Background: Illicitly manufactured fentanyl (IMF) prevalence has increased. However, there is uncertainty about naloxone dose(s) used by nonmedical bystanders to reverse opioid overdoses in the context of increasing IMF. Methods: We used community naloxone distribution program data about naloxone doses and fatal opioid overdoses from the Allegheny County Medical Examiner. From January 2013 to December 2016, staff interviewed participants who administered naloxone in response to 1072 overdoses. We calculated frequencies, percentages, and conducted a 1-way analysis of variance (ANOVA). Results: Despite increases in fentanyl-contributed deaths, there were no statistically significant differences between any of the 4 years (2013–2016) on average number of naloxone doses used by participants to reverse an overdose (F = 0.88; P = .449). Conclusion: Even though IMF is more potent than heroin and is a rapidly increasing contributor to drug overdose deaths in Allegheny County, the average dose of naloxone administered has not changed. Our findings differ from studies in different areas also experiencing increasing IMF prevalence. Additional investigations are needed to clarify the amount of naloxone needed to reverse opioid overdoses in the community caused by new synthetic opioids.     

Evaluation of overdose prevention trainings in New York City: Knowledge and self-efficacy among participants 12 months after training

ABSTRACT

Background: Prevention of unintentional opioid overdose deaths is effective through overdose prevention trainings (OPTs), in which laypersons are taught overdose response through six actions. This longitudinal study examines trainee knowledge 12 months after OPT completion. Methods: Participants were enrolled following OPT at six sites. At the 12-month follow-up, participants were asked to name the drug overdoses that naloxone reverses and name overdose response actions. A 6-point scale was created and was comprised of the number of correct overdose response actions mentioned (check breathing; administer sternum rub; call 911; give rescue breathing; administer naloxone; put victim in recovery position). Mean knowledge was compared by participant sociodemographic characteristics, confidence, and site of OPT training (indoors versus outdoors). Results: Of 344 OPT participants, 273 were reached at 12 months. Nearly all (99%) participants identified that naloxone reverses heroin overdoes; 77% identified that naloxone reverses opioid analgesics overdoses; and 68% identified that naloxone reverses methadone overdoses. Overdose response actions most frequently mentioned were giving naloxone (86%) and calling 911 (76%). The remaining four actions were mentioned by less than 40% of participants. Overall mean knowledge score was 2.7 out of 6. Mean knowledge scores were higher for college graduates than those with less than college education (3.2 vs 2.6, P < 0.001), for those who felt very confident (mean score [ms] = 2.9), compared to somewhat confident (ms = 2.4) and a little or not at all confident (ms = 1.5) in their ability to reverse an overdose (P < .001), and for indoor-training recipients (3.0 vs 2.5, P = 0.02). There were no differences in mean knowledge scores for trainees by age, race, or gender. Conclusions: These findings suggest the need for several improvements in OPT curriculum, including emphasis on naloxone reversal of opioid analgesic and methadone overdoses, and all 6 rescue actions. Lower knowledge scores among outdoor-trained participants likely reflect session brevity, suggesting that outdoor trainings need to be enhanced.     

Faculty education in addiction training (FEAT): Evaluating an online training program for multidisciplinary health professions educators

Abstract

Background: Many health professionals lack adequate training needed to effectively address alcohol and other drug (AOD)-related problems. Building upon our previously successful in-person faculty training programs, we designed and pilot tested the brief online Faculty Education in Addiction Training (FEAT) Program for social work and internal medicine residency faculty. The present study examines baseline and post-FEAT Program AOD knowledge and teaching confidence and preparedness among faculty participants. Methods: The FEAT Program curriculum included didactic videos, online engagement with content experts, recommended readings, and a live virtual classroom experience. Participants completed self-assessments of knowledge and teaching confidence and preparedness pre- and post-FEAT program. Results: In this pilot test, thirty faculty completed the FEAT program: 15 social work and 15 internal medical residency program faculty. Both groups showed significant improvement (p?<?0.001) in overall AOD-related knowledge with medium-to-large effects (Cohen’s d?=?1.83 [social work], 0.72 [medicine]). Both groups showed significant increases in teaching confidence (p?<?0.001) for all items with large effects (Cohen’s d values range from 1.08 to 1.92) and significant increases and large effects for all teaching preparedness items for social work (at least p?<?0.01 | Cohen’s d range = 1.03–1.56) and internal medical residency faculty (p?<?0.001 | Cohen’s d range = 1.08–1.69). Conclusions: Multidisciplinary health professions educators’ AOD knowledge and teaching confidence and preparedness can be improved by participation in a brief online program designed to circumvent the logistical and fiscal challenges presented by in-person programs.     

Barriers to naloxone use and acceptance among opioid users,first responders,and emergency department providers in New Hampshire,USA

BackgroundThe United States is in the midst of a devastating opioid crisis, and the state of New Hampshire (NH) has been disproportionately impacted. Naloxone is an opioid overdose reversal medication that is critical for saving lives. This study was conducted to understand emergency responders’ and opioid users’ experiences with, and opinions about, naloxone use and distribution in NH.MethodsSemi-structured interviews were conducted with 76 opioid users and 36 emergency responders in six NH counties in 2016–2017. Interviews focused on respondents’ experiences with opioid use and overdose. Interviews were transcribed, coded, and reviewed for consensus among coders. Directed content analysis was used to review high-level domains and identify subthemes.ResultsUsers and responders largely agreed that naloxone had become increasingly available in NH at the time of the study. Reported responder barriers to naloxone acceptance included perceptions that increased naloxone availability may enable riskier opioid use and fails to address the underlying causes of addiction. Reported opioid-user barriers included cost, legality, and lack of knowledge regarding distribution locations and indications for use.ConclusionOpioid users’ and emergency responders’ perceptions about naloxone may limit the optimal use of naloxone within the community. This study identifies opportunities to address misconceptions about naloxone and challenges in accessing naloxone, which may improve opioid overdose prevention strategies.     

Social and structural aspects of the overdose risk environment in St. Petersburg, Russia

BackgroundWhile overdose is a common cause of mortality among opioid injectors worldwide, little information exists on opioid overdoses or how context may influence overdose risk in Russia. This study sought to uncover social and structural aspects contributing to fatal overdose risk in St. Petersburg and assess prevention intervention feasibility.MethodsTwenty-one key informant interviews were conducted with drug users, treatment providers, toxicologists, police, and ambulance staff. Thematic coding of interview content was conducted to elucidate elements of the overdose risk environment.ResultsSeveral factors within St. Petersburg's environment were identified as shaping illicit drug users’ risk behaviours and contributing to conditions of suboptimal response to overdose in the community. Most drug users live and experience overdoses at home, where family and home environment may mediate or moderate risk behaviours. The overdose risk environment is also worsened by inefficient emergency response infrastructure, insufficient cardiopulmonary or naloxone training resources, and the preponderance of abstinence-based treatment approaches to the exclusion of other treatment modalities. However, attitudes of drug users and law enforcement officials generally support overdose prevention intervention feasibility. Modifiable aspects of the risk environment suggest community-based and structural interventions, including overdose response training for drug users and professionals that encompasses naloxone distribution to the users and equipping more ambulances with naloxone.ConclusionLocal social and structural elements influence risk environments for overdose. Interventions at the community and structural levels to prevent and respond to opioid overdoses are needed for and integral to reducing overdose mortality in St. Petersburg.     

Use of online opioid overdose prevention training for first-year medical students: A comparative analysis of online versus in-person training

Purpose: In response to the opioid epidemic and efforts to expand substance use education in medical school, the authors introduced opioid overdose prevention training (OOPT) with naloxone for all first-year medical students (MS1s) as an adjunct to required basic life support training (BLST). The authors previously demonstrated improved knowledge and preparedness following in-person OOPT with BLST; however, it remains unclear whether online-administered OOPT would produce comparable results. In this study, the authors perform a retrospective comparison of online-administered OOPT with in-person-administered OOPT. Objectives: To compare the educational outcomes: knowledge, preparedness, and attitudes, for online versus in-person OOPT. Methods: In-person OOPT was administered in 2014 and 2015 during BLST, whereas online OOPT was administered in 2016 during BLST pre-work. MS1s completed pre- and post-training tests covering 3 measures: knowledge (11-point scale), attitudes (66-point scale), and preparedness (60-point scale) to respond to an opioid overdose. Online scores from 2016 and in-person scores from 2015 were compared across all 3 measures using analysis of covariance (ANCOVA) methods. Results: After controlling for pre-test scores, there were statistical, but no meaningful, differences across all measures for in-person- and online-administered training. The estimated differences were knowledge: ?0.05 (0.5%) points (95% confidence interval [CI]: ?0.47, 0.36); attitudes: 0.65 (1.0%) points (95% CI: ?0.22, 1.51); and preparedness: 2.16 (3.6%) points (95% CI: 1.04, 3.28). Conclusions: The educational outcomes of online-administered OOPT compared with in-person-administered OOPT were not meaningfully different. These results support the use of online-administered OOPT. As our study was retrospective, based on data collected over multiple years, further investigation is needed in a randomized controlled setting, to better understand the educational differences of in-person and online training. Further expanding OOPT to populations beyond medical students would further improve generalizability.     

Exploring social work student education: The effect of a harm reduction curriculum on student knowledge and attitudes regarding opioid use disorders

Background: This study evaluates the degree to which a harm reduction intervention course module impacted Master of Social Work (MSW) students’ knowledge and attitudes towards addressing opioid use disorder issues and clients. Methods: Using a mixed-methods approach, data from 124 MSW students were collected between 2011 and 2015. Students completed a 3-hour course module that focused on harm reduction philosophy and interventions specifically for opioid use disorders. Students completed pre- and posttest of the Harm Reduction Attitude Scale. Students were also engaged in focus groups to gain a better understanding of how and if their knowledge and attitudes changed. Results: Overall, attitudes towards harm reduction approaches for opioid use disorder shifted favorably following the course module. Paired t-test results show a statistically significant difference in the mean scores for pretest attitudes (M = 2.64, SD = 0.16) and posttest attitudes (M = 2.86, SD = 0.12) among social work students. This trend remained consistent despite treatment orientation and having a family history of substance use. Conclusion: Given the increased capacity for social work students to encounter clients with opioid use disorders, it is important to ensure that students are provided with relevant and accurate information related to client-centered approaches such as the harm reduction model to address opioid use disorders. Moreover, given the dearth of social work programs that have and required substance use disorder courses, it is imperative for schools of social work to ensure that students are provided with more than practical information, which is often gained during field placement.     

Prospective comparative assessment of buprenorphine overdose with heroin and methadone: Clinical characteristics and response to antidotal treatment

Buprenorphine is a partial opioid agonist with a “ceiling effect” for respiratory depression. Despite this, it has been associated with severe overdoses. Conflicting data exist regarding its response in overdose to naloxone. We compared clinical overdose characteristics of buprenorphine with heroin and methadone and assessed responses to naloxone and flumazenil. Patients admitted to two intensive care units with severe opioid overdoses were enrolled into this 4-year prospective study. Urine and blood toxicological screening were performed to identify overdoses involving predominantly buprenorphine, heroin, or methadone. Eighty-four patients with heroin (n = 26), buprenorphine (n = 39), or methadone (n = 19) overdoses were analyzed. In the buprenorphine group, sedative drug coingestions were frequent (95%), whereas in the methadone group, suicide attempts were significantly more often reported (p = .0007). Buprenorphine overdose induced an opioid syndrome not differing significantly from heroin and methadone in mental status (as measured by Glasgow Coma Score) or arterial blood gases. Mental status depression was not reversed in buprenorphine overdoses with naloxone (0.4–0.8 mg) but did improve with flumazenil (0.2–1 mg) if benzodiazepines were coingested. In conclusion, buprenorphine overdose causes an opioid syndrome clinically indistinguishable from heroin and methadone. Although mental status and respiratory depression are often unresponsive to low-dose naloxone, flumazenil may be effective in buprenorphine overdoses involving benzodiazepines.     

Law enforcement attitudes towards naloxone following opioid overdose training

ABSTRACT

Background: Opioid intoxication and overdoses are life-threatening emergencies requiring rapid treatment. One response to this has been to train law enforcement to detect the signs of an opioid overdose and train them to administer naloxone to reverse the effects. Although not a new concept, few studies have attempted to examine this policy. Methods: At 4 different locations in Indiana, law enforcement personnel were trained to detect the signs of an opioid-related overdose and how to administer naloxone to reverse the effects of the overdose. Pre and post surveys were administered at each location (N = 97). To examine changes in attitudes following training, the authors included items from the Opioid Overdose Attitudes Scale (OOAS), which measures respondents' competency, concerns, and readiness to administer naloxone. Results: Among the full sample, naloxone training resulted in significant increases in competency, concerns, and readiness. Examining changes in attitudes by each location revealed that the training had the greatest effect on competency to administer naloxone and in easing concerns that law enforcement personal might have in administering naloxone. Conclusions: This study adds to others in showing that law enforcement personnel are receptive to naloxone training and that the OOAS is able to capture these attitudes. This study advances this literature by examining pre-post changes across multiple locations. As the distribution of naloxone continues to proliferate, this study and the OOAS may be valuable towards the development of an evidence-based training model for law enforcement.     

The extent of and factors associated with self-reported overdose and self-reported receipt of naloxone among people who inject drugs (PWID) in England,Wales and Northern Ireland

BackgroundOverdose is a major cause of death among PWID, and for opioid overdoses naloxone administration can reduce harm. However, globally there is limited national level data on the extent of non-fatal overdose and naloxone uptake. The first national level data on the extent of self-reported overdose and self-reported receipt of naloxone among UK PWID, providing a baseline to monitor the impact of the recent policy change regarding naloxone availability, is presented.MethodsData on self-reported overdose and receipt of naloxone during the preceding year for 2013–2014 from a national survey of PWID was analysed. Participants who reported injecting during the preceding year were included.ResultsParticipants (3850) were predominantly male (75%); mean age was 36 years. The most commonly injected drugs were: heroin (91%), crack (45%) and amphetamine (29%). 15% (591) reported overdosing during the preceding year. There were no differences in the proportion reporting overdose by age or gender, but overdose was more common among those who: injected multiple drugs; recently ceased addiction treatment; injected with used needles/syringes; ever had transactional sex; had used a sexual health clinic or emergency department and lived in Wales or Northern Ireland. Among those reporting an overdose during the preceding year, a third reported two to four overdoses and 7.5% five or more overdoses; half reported receiving naloxone. Those reporting naloxone receipt in the preceding year were more likely to: live in Wales or Northern Ireland; ever received used needles/syringes; ever been imprisoned; and less likely to have injected two drug types.ConclusionThese data provide a baseline for monitoring the impact of the 2015 UK policy change to improve take-home naloxone access. Interventions tackling overdose should promote naloxone awareness and access, and target those who; are poly-drug injectors, have ceased treatment, share needles/syringes and whose drug use links to sexual activity.     

Evaluation of an overdose prevention and response training programme for injection drug users in the Skid Row area of Los Angeles,CA

BackgroundFatal opioid overdose is a significant cause of mortality among injection drug users (IDUs).MethodsWe evaluated an overdose prevention and response training programme for IDUs run by a community-based organisation in Los Angeles, CA. During a 1-h training session participants learned skills to prevent, recognise, and respond to opioid overdoses, including: calling for emergency services, performing rescue breathing, and administering an intramuscular injection of naloxone (an opioid antagonist). Between September 2006 and January 2008, 93 IDUs were trained. Of those, 66 (71%) enrolled in the evaluation study and 47 participants (71%) completed an interview at baseline and 3-month follow-up.ResultsTwenty-one percent of participants were female, 42% were white, 29% African American, and 18% Latino. Most were homeless or lived in temporary accommodation (73%). We found significant increases in knowledge about overdose, in particular about the use of naloxone. Twenty-two participants responded to 35 overdoses during the follow-up period. Twenty-six overdose victims recovered, four died, and the outcome of five cases was unknown. Response techniques included: staying with the victim (85%), administering naloxone (80%), providing rescue breathing (66%), and calling emergency services (60%). The average number of appropriate response techniques used by participants increased significantly from baseline to follow-up (p < 0.05). Half (53%) of programme participants reported decreased drug use at follow-up.ConclusionOverdose prevention and response training programmes may be associated with improved overdose response behaviour, with few adverse consequences and some unforeseen benefits, such as reductions in personal drug use.     

Opioid overdose in the age of fentanyl: Risk factor differences among subpopulations of overdose survivors

BackgroundAlthough fentanyl is the drug most frequently implicated in overdose deaths, the association between overdose risk and attitudes and behaviors surrounding fentanyl in opioid-using communities has remained understudied. Possible subpopulation differences in fentanyl-related overdose risk remain equally unexamined. This paper addresses these gaps by exploring the association between overdose and fentanyl-related attitudes/behaviors in three subpopulations of overdose survivors.MethodsIn this cross-sectional study, we sampled 432 individuals who currently or recently used opioids from New Jersey methadone and acute residential detoxification programs. Using multinomial regression analysis, we compared overdose risk factors, including fentanyl-related attitudes/behaviors, of those who never overdosed with three subgroups of overdose survivors who experienced: 1. recent overdoses occurring after, but not before, fentanyl expansion; 2. past overdoses occurring before, but not after, fentanyl expansion; 3. persistent overdoses occurring before and after fentanyl expansion.ResultsForty percent of respondents had knowingly used fentanyl and 38% deliberately sought overdose-implicated drugs. Respondents with persistent overdoses represented under 10% of the sample but accounted for 44% of all lifetime overdoses (x̅ =8.03 vs. 1.71 for the full sample). This was also the only subgroup for whom PTSD (AOR=3.84; 95%CI=1.45–10.16; p=.01) and fentanyl-seeking (AOR=1.50; 95% CI=1.16–1.94; p=.01) were significant overdose risk factors. Those with recent overdoses engaged in frequent drug combining (AOR=2.28; 95% CI=1.19–6.98; p=.05), which could have led to inadvertent fentanyl use. Those with past overdoses were not at overdose risk from fentanyl-seeking or drug combining and had rates of methadone treatment comparable to rates of those with no overdoses.ConclusionHarm reduction strategies will need to address consumers’ evolving drug preferences as fentanyl continues to saturate local drug markets. Targeting comprehensive interventions, including mental health treatment, to the small group of opioid users with longstanding overdose histories may reduce the burden of overdose in opioid-using communities.
