The Emergency Department as an Opportunity for Naloxone Distribution

Willingness to Provide Naloxone Resources for Patients at Risk of Opioid Overdose: A National Survey of Emergency Registered Nurses

INTRODUCTION

Opioid-related events continue to claim lives in the United States at alarming rates. Naloxone-dispensing rates fall dramatically short of national expectations. Emergency registered nurses are uniquely poised to connect at-risk patients with naloxone resources. This study sought to (1) describe the emergency registered nurses' willingness to provide naloxone resources and (2) explore variables that may influence the nurse's willingness to provide resources.

METHODS

A cross-sectional, survey-based design was deployed using an online branch logic approach to include a national sample of emergency registered nurses. The Willingness to Provide, a validated questionnaire, measured the registered nurse's willingness to provide naloxone resources for patients at risk of opioid overdose. Eight variables were assessed for potential influence on willingness.

RESULTS

A total of 159 nurses from 32 states and the District of Columbia completed the online survey via the Research Electronic Data Capture platform. The results revealed a mean Willingness to Provide score of 38.64 indicating a willingness to provide naloxone resources. A statistically significant relationship was identified between the nurse's willingness and years of nursing experience (P = .001), knowledge (P = .015), desire (P = .001), and responsibility (P < .001).

DISCUSSION

In this representative sample, emergency nurses are willing to provide naloxone resources; furthermore, results indicate that higher knowledge, desire, and responsibility scores increase the nurse's willingness to provide naloxone resources; with education and clear expectations, emergency nurses may be able to improve the connection of patients at risk of opioid overdose with naloxone, a potentially lifesaving connection.

Naloxone distribution programs in the emergency department: A scoping review of the literature

This scoping review summarized the literature regarding naloxone distribution from emergency departments (EDs) without a prescription. Our intention was to examine various naloxone distribution programs, their methodologies, and the level of effectiveness of each. Understanding these key aspects of naloxone distribution could lead to improved standardized protocols, saving countless additional lives from opioid overdose. This review evaluated studies reporting naloxone distribution from EDs in the United States. The included studies were written in English and published between January 1, 2017, and December 31, 2022. Searches were performed using PubMed and Embase. A total of 129 studies were reviewed, with only 12 meeting the necessary criteria for analysis. Heterogeneity was found across naloxone distribution programs, including how patients were identified, how naloxone was dispensed to patients, and the specific naloxone products made available. The protocols included various methods, such as patient screening, where information used for this screening was sometimes obtained from health records or patient interviews. Some programs detailed only the distribution of naloxone, while others included additional interventions such as behavior counseling, peer support, and education. In four studies, patients received buprenorphine with naloxone kits. The various programs differed in their implementation but were generally successful in improving naloxone distribution. However, among the studies reviewed, the percentage of ED patients receiving naloxone varied from ∼30% to 70%, suggesting that certain program elements may be more impactful. Further research is needed to identify key elements of the most impactful programs in order to improve naloxone distribution and improve patient odds of surviving an opioid overdose.

Layperson knowledge on naloxone and medications for opioid use disorder in an urban population: a cross sectional survey study

BACKGROUND AND OBJECTIVES

There has been little research in an urban population regarding knowledge of harm reduction measures and treatment options. The objective of our study was to evaluate knowledge and perceptions of harm reduction measures and types of treatment available for opioid use disorder among patients and family in an urban emergency department (ED) waiting room.

METHODS

We conducted a single center, cross-sectional survey study that occurred between September 2021 and August 2022. A convenience sample of patients and family members that were above 18 and English speaking were recruited by research assistants. Participants were assessed on knowledge and preferences around drug treatment options and harm reduction. Data were summarized using descriptive statistics and compared using the Freeman-Halton/Kruskall-Wallis/Mann-Whitney U tests. p-Values were reported at the 0.05 significance level.

RESULTS

We collected 200 responses. Of these, 104 people had a connection to someone with a substance use disorder (SUD) and 50 had an SUD. Of those who had a connection to someone with SUD, 63 had heard of naloxone (60.6%, CI: [50.5, 69.9]). Fewer than 60% of respondents in each group had heard of Medications for Opioid Use Disorder (MOUD) (p = 0.46) and fewer than 50% thought that among people who use drugs that they knew would be interested in receiving treatment (p = 0.10).

DISCUSSION AND CONCLUSIONS

Our study found that among people who came to an urban emergency department, there was a lack of awareness of harm reduction and MOUD. Interventions should be put into place to educate on the importance of MOUD and harm reduction.

Expanding expedited partner therapy and HIV prophylaxis in the emergency department

PURPOSE

Sexually transmitted infections (STIs) continue to have a disproportionate impact on individuals belonging to sexual, gender, and racial minorities. Across the nation, many emergency medicine pharmacists (EMPs) possess the skills and knowledge to expand the provision of expedited partner therapy (EPT) for STIs and provide HIV prophylaxis within existing practice frameworks. This report serves as a call to action for expanded provision of EPT and HIV prophylaxis by EMPs and highlights current barriers and solutions to increase pharmacist involvement in these practice areas.

SUMMARY

Emergency medicine pharmacy practice continues to expand to allow for limited prescribing authority through collaborative practice agreements (CPAs). In recent years, CPA restrictions have been changed to facilitate treatment of more patients with less bureaucracy. This report addresses the unique challenges and opportunities for expanding EPT and HIV pre- and postexposure prophylaxis provision by pharmacists in emergency departments (EDs). Furthermore, current strategies and treatments for EPT, such as patient-delivered partner therapy and HIV prophylaxis, are discussed. Pharmacist involvement in STI treatment and HIV prevention is a key strategy to increase access to high-risk populations with high ED utilization and help close current gaps in care.

CONCLUSION

Expanding EMP provision of EPT and HIV prophylaxis may be beneficial to reducing the incidence of STIs and HIV infection in the community. CPAs offer a feasible solution to increase pharmacist involvement in the provision of these treatments. Legislative efforts to expand pharmacist scope of practice can also contribute to increasing access to EPT and HIV prophylaxis. With these efforts, EMPs can play an essential role in the fight against STIs and HIV.

Treatment Updates for Pain Management and Opioid Use Disorder

The medical community has proposed several clinical recommendations to promote patient safety and health amid the opioid overdose public health crisis. For a frontline practicing physician, distilling the evidence and implementing the latest guidelines may prove challenging. This article aims to highlight pertinent updates and clinical care pearls as they relate to primary care management of chronic pain and opioid use disorder.

Demographics and Clinical Characteristics of Patients With Opioid Use Disorder and Offered Medication-Assisted Treatment in the Emergency Department

Background and objective The opioid use disorder (OUD) epidemic is a persistent public health crisis in the United States. Medication-assisted treatment (MAT) with opioid agonists, including buprenorphine, is an effective treatment and is commonly initiated in the emergency department (ED). This study describes the demographics and clinical characteristics of OUD patients presenting to the ED and evaluated for MAT. Methodology A retrospective, single-center descriptive study of 129 adult patients presenting to the ED between July 2018 and July 2020 with OUD and evaluated for MAT. Results A total of 129 patients were assessed for MAT. About half (53%) received MAT; the remaining received only a referral (35%) or declined any intervention (12%). The median age was 36 years interquartile range (IQR, 28-46 years) and predominantly male (73%), single (65%), white (73%), unemployed (57%) with public insurance (55%), and without a primary care physician (58%). Majority of the patients presented with opioid withdrawal (62%) or intoxication (15%), while 23% presented with other complaints. About half of the patients (51%) were discharged with a naloxone kit. The majority of the patients were induced with buprenorphine with 4 mg or less (54%) and only 6% of patients received repeat dosing. Conclusions Male, white patients who are unmarried and unemployed, lack primary care follow-up, and rely on public insurance are more likely to be candidates for MAT. Providers should always maintain a high suspicion of opioid misuse and optimize treatment for those in withdrawal. Understanding these characteristics in conjunction with recent health policy changes will hopefully guide and encourage ED-initiated interventions in combating the opioid crisis.

The effectiveness of a noninterruptive alert to increase prescription of take-home naloxone in emergency departments

OBJECTIVE

Opioid-related overdose (OD) deaths continue to increase. Take-home naloxone (THN), after treatment for an OD in an emergency department (ED), is a recommended but under-utilized practice. To promote THN prescription, we developed a noninterruptive decision support intervention that combined a detailed OD documentation template with a reminder to use the template that is automatically inserted into a provider's note by decision rules. We studied the impact of the combined intervention on THN prescribing in a longitudinal observational study.

METHODS

ED encounters involving an OD were reviewed before and after implementation of the reminder embedded in the physicians' note to use an advanced OD documentation template for changes in: (1) use of the template and (2) prescription of THN. Chi square tests and interrupted time series analyses were used to assess the impact. Usability and satisfaction were measured using the System Usability Scale (SUS) and the Net Promoter Score.

RESULTS

In 736 OD cases defined by International Classification of Disease version 10 diagnosis codes (247 prereminder and 489 postreminder), the documentation template was used in 0.0% and 21.3%, respectively (P < .0001). The sensitivity and specificity of the reminder for OD cases were 95.9% and 99.8%, respectively. Use of the documentation template led to twice the rate of prescribing of THN (25.7% vs 50.0%, P < .001). Of 19 providers responding to the survey, 74% of SUS responses were in the good-to-excellent range and 53% of providers were Net Promoters.

CONCLUSIONS

A noninterruptive decision support intervention was associated with higher THN prescribing in a pre-post study across a multiinstitution health system.

Trends in naloxone prescribed at emergency department discharge: A national analysis (2012-2019)

BACKGROUND

While having access to naloxone is recommended for patients at risk for opioid overdose, little is known about trends in national naloxone prescribing rates in emergency departments (EDs) both for co-prescription with opioids and for patients who presented with opioid abuse or overdose. This study aims to evaluate the change in naloxone prescribing and opioid/naloxone co-prescribing at discharge using national data.

METHODS

We conducted an IRB exempt retrospective review of data collected by the National Hospital Ambulatory Medical Care Survey from 2012 to 2019. The primary outcome was trend in rate of naloxone prescribing at discharge from ED visits. We also computed the proportion of visits where naloxone was both administered in the ED and prescribed at discharge, where naloxone and opioids were co-prescribed at discharge, and where an opioid was administered during the ED visit and naloxone was prescribed at discharge. All data were summarized using descriptive statistics and Spearman's Rho (SR) or Pearson's correlation (PR) were used to describe trends.

RESULTS

There was an estimated total of 250,365 patient visits where naloxone was prescribed at discharge with an increasing rate over time (0% of all ED visits in 2012 to 0.075% in 2019, p = 0.002). There were also increases in naloxone being both administered in the ED and prescribed at discharge (PC: 0.8, p = 0.02) as well as in naloxone and opioid co-prescribing (SR: 0.76, P = 0.03). There was an increase in utilization of opioids during the ED visit and naloxone prescribing at discharge for the same visit (SR: 0.80, p = 0.02).

CONCLUSION

There are increases in naloxone prescribing at discharge, naloxone and opioid co-prescribing, and opioid utilization during the same visit where naloxone is prescribed at discharge. Future studies should be done to confirm such trends, and targeted interventions should be put into place to increase access to this life-saving antidote.

Motivation to Carry Naloxone: A Qualitative Analysis of Emergency Department Patients

PURPOSE

Our aim was to explore perspectives of patients who received naloxone in the emergency department (ED) about (1) naloxone carrying and use following an ED visit and (2) motivation for performing these behaviors.

DESIGN

Semi-structured interviews of patients prescribed naloxone at ED discharge.

SETTINGS

Three urban academic EDs in Philadelphia, PA.

PARTICIPANTS

25 participants completed the in-depth, semi-structured interviews and demographic surveys. Participants were majority male, African American, and had previously witnessed or experienced an overdose.

METHODS

Interviews were recorded, transcribed and analyzed using content analysis. We used a hybrid inductive-deductive approach that included prespecified and emergent themes.

RESULTS

We found that naloxone carrying behavior was variable and influenced by four main motivators: (1) naloxone access; (2) personal experience and salience of naloxone, (3) comfort with naloxone administration, and (4) societal influences on naloxone carrying. In particular, those with personal history of overdose or close friends or family at risk were motivated to carry naloxone.

CONCLUSIONS

Participants in this study reported several important motivators for naloxone carrying after an ED visit, including ease of naloxone access and comfort, perceived risk of experiencing or encountering an overdose, and social influences on naloxone carrying behaviors. EDs, health systems, and public health officials should consider these factors influencing motivation when designing future interventions to increase access, carrying, and use of naloxone.

Pilot testing fentanyl test strip distribution in an emergency department setting: Experiences, lessons learned, and suggestions from staff

OBJECTIVES

Fentanyl test strips (FTSs) are increasingly used to address fentanyl contamination of the illicit drug supply by testing a drug for the presence of fentanyl, allowing people who use drugs (PWUD) to engage in overdose prevention. While emergency departments (EDs) have implemented various harm reduction strategies for PWUD, to date distribution of FTSs in EDs is limited and not evaluated. Thus, we sought to explore ED staff experiences distributing FTSs.

METHODS

Twenty-one staff serving different roles (e.g., physician, nurse, technician, social worker, certified recovery specialist) within two urban EDs in a major metropolitan area were enrolled in a pilot study to distribute FTS to patients who use drugs. Participants were interviewed about their experience at 3 weeks and again at 3 months. Interviews were recorded, transcribed verbatim, and coded using a conventional content analysis approach.

RESULTS

All participants endorsed the utility of FTS distribution in the ED. Across 42 interviews, participants discussed evolving strategies to approach patients about FTS, primarily favorable patient reactions to FTSs, improved dynamics between participants and patients, mixed intervention support from other staff, and named challenges of FTS distribution and recommendations to make FTS distribution in the ED widespread. Recommendations included medical records prompts to offer FTS, offering via different types of staff, and offering FTS during triage.

CONCLUSIONS

Implementing FTS distribution may improve patient rapport while providing patients with tools to avoid a fentanyl overdose. Participants generally reported positive experiences distributing FTSs within the ED but the barriers they identified limited opportunities to make distribution more integrated into their workflow. EDs considering this intervention should train staff on FTSs and how to identify and train patients and explore mechanisms to routinize distribution in the ED environment.

A pilot study of a mixed-method approach to design an ED-based peer mHealth referral tool for HIV/HCV and opioid overdose prevention services

BACKGROUND

The intersecting epidemics of opioid misuse, injection drug use, and HIV/HCV have resulted in record overdose deaths and sustained high levels of HIV/HCV transmissions. Literature on social networks suggests opportunities to connect people who use drugs (PWUD) and their peers to HIV/HCV and opioid overdose prevention services. However, little evidence exists on how to design such peer referral interventions in emergency department (ED) settings.

METHODS

A mixed-method study was conducted to assess the feasibility of an mHealth-facilitated 'patient to peer social network referral program' for PWUD. In-depth interviews (IDIs) and quantitative surveys were conducted with urban ED patients (n = 15), along with 3 focus group discussions (FGDs) (n = 19).

RESULTS

Overall, 34 participants were enrolled (71 % males, 53 % Black). 13/15 IDI participants reported a history of opioid overdose; all had witnessed overdose events; all received HIV/HCV testing. From survey responses, most would invite their peers for HIV/HCV testing and naloxone training; and anticipated peers to accept referrals (HIV: 60 %, HCV: 73 %, naloxone: 93 %). Qualitative data showed PWUD shared health-related information with each other but preferred word of mouth rather than text messages. Participants used smartphones regularly and suggested using Internet advertising for prevention services. Participants expressed enthusiasm for ED-based peer mHealth referral platform to prevention services, as well as referring their peers to proposed services, with monetary incentives.

CONCLUSION

ED-based peer referral intervention to HIV/HCV testing and naloxone training was viewed favorably by PWUD. Frequent smartphone use among PWUD suggests that the medium could be a promising mode for peer referral.

The Identification of Subphenotypes and Associations with Health Outcomes in Patients with Opioid-Related Emergency Department Encounters Using Latent Class Analysis

The emergency department (ED) is a critical setting for the treatment of patients with opioid misuse. Detecting relevant clinical profiles allows for tailored treatment approaches. We sought to identify and characterize subphenotypes of ED patients with opioid-related encounters. A latent class analysis was conducted using 14,057,302 opioid-related encounters from 2016 through 2017 using the National Emergency Department Sample (NEDS), the largest all-payer ED database in the United States. The optimal model was determined by face validity and information criteria-based metrics. A three-step approach assessed class structure, assigned individuals to classes, and examined characteristics between classes. Class associations were determined for hospitalization, in-hospital death, and ED charges. The final five-class model consisted of the following subphenotypes: Chronic pain (class 1); Alcohol use (class 2); Depression and pain (class 3); Psychosis, liver disease, and polysubstance use (class 4); and Pregnancy (class 5). Using class 1 as the reference, the greatest odds for hospitalization occurred in classes 3 and 4 (Ors 5.24 and 5.33, p < 0.001) and for in-hospital death in class 4 (OR 3.44, p < 0.001). Median ED charges ranged from USD 2177 (class 1) to USD 2881 (class 4). These subphenotypes provide a basis for examining patient-tailored approaches for this patient population.

Piloting a statewide emergency department take-home naloxone program: Improving the quality of care for patients at risk of opioid overdose

BACKGROUND

Emergency department (ED) patients with nonfatal opioid overdose are at high risk for subsequent fatal overdose, yet ED programs aimed at reducing harm from opioid use remain underdeveloped.

OBJECTIVES

The objective was to pilot a statewide ED take-home naloxone program and improve the care of patients with opioid use disorder (OUD) and risky drug use through training and interprofessional network building.

METHODS

Nine hospital EDs with pharmacy, nurse, and physician champions were recruited, surveyed, and trained. Take-home naloxone rescue kits were developed, disseminated, and tracked. Two overdose prevention summits were convened prior to the COVID pandemic, and two X-waiver training courses aimed at emergency physicians and advanced practice providers were arranged, both in person and virtual.

RESULTS

A total of 872 naloxone rescue kits were distributed to ED patients at risk of opioid overdose during the first phase of this project, and more than 140 providers were trained in the use of medications for OUD in acute care settings.

CONCLUSIONS

A statewide ED take-home naloxone program was shown to be feasible across a range of different hospitals with varying maturity in preexisting OUD resources and capabilities. Future work will be aimed at both expanding and measuring the effectiveness of this work.

Businesses in high drug use areas as potential sources of naloxone during overdose emergencies

INTRODUCTION

Naloxone distribution remains a cornerstone of a public health approach to combating the ongoing opioid overdose crisis. Most distribution programs focus on providing naloxone to individuals who use drugs or those closely associated with them (e.g., family). Utilizing businesses as fixed location sources of naloxone could be a valuable supplemental strategy to preventing fatal overdoses that is underexplored in the literature.

METHODS

We surveyed business owners and employees (N = 149) located in neighborhoods characterized by high rates of drug use in Baltimore City. Participants reported their interactions with people who use drugs as well as if they had heard of naloxone, if the business had naloxone on the premises, and how many employees were trained to use naloxone.

RESULTS

Most participants reported seeing individuals under the influence of drugs (93%), public drug use (80%), and overdose (66%) while at work. 66% of participants had heard of naloxone. Among those who had heard of naloxone, only 39% reported that there was a naloxone kit in the business and 28% of businesses had multiple employees trained to use naloxone.

CONCLUSIONS

Businesses are underutilized as potential reliable sources of naloxone. While study participants reported high levels of exposure to drug use and overdose in and around their businesses, their ability to intervene was limited. Efforts to train employees to respond to overdoses and to keep naloxone on site are warranted to supplement existing naloxone distribution efforts and can help empower business staff to help prevent overdose mortality in their communities.

Naloxone and Buprenorphine Prescribing Following US Emergency Department Visits for Suspected Opioid Overdose: August 2019 to April 2021

STUDY OBJECTIVE

Nonfatal emergency department (ED) visits for opioid overdose are important opportunities to prescribe naloxone and buprenorphine, both of which can prevent future overdose-related mortality. We assessed the rate of this prescribing using national data from August 2019 to April 2021, a period during which US opioid overdose deaths reached record levels.

METHODS

We conducted a retrospective cohort analysis using Symphony Health's Integrated Dataverse, which includes data from 5,800 hospitals and 70,000 pharmacies. Of ED visits for opioid overdose between August 4, 2019, and April 3, 2021, we calculated the proportion with at least 1 naloxone prescription within 30 days and repeated this analysis for buprenorphine. To contextualize the naloxone prescribing rate, we calculated the proportion of ED visits for anaphylaxis with at least 1 prescription for epinephrine-another life-saving rescue medication-within 30 days.

RESULTS

Analyses included 148,966 ED visits for opioid overdose. Mean weekly visits increased 23.6% during the period between April 26, 2020 and October 3, 2020 compared with the period between August 4, 2019 to April 25, 2020. Visits declined to prepandemic levels between October 4, 2020 and March 13, 2021, after which visits began to rise. Naloxone and buprenorphine were prescribed within 30 days at 7.4% and 8.5% of the 148,966 visits, respectively. The naloxone prescribing rate (7.4%) was substantially lower than the epinephrine prescribing rate (48.9%) after ED visits for anaphylaxis.

CONCLUSION

Between August 4, 2019, and April 3, 2021, naloxone and buprenorphine were only prescribed after 1 in 13 and 1 in 12 ED visits for opioid overdose, respectively. Findings suggest that clinicians are missing critical opportunities to prevent opioid overdose-related mortality.

Emergency department visits and trends related to cocaine, psychostimulants, and opioids in the United States, 2008-2018

BACKGROUND

Drug-related emergency department (ED) visits are escalating, especially for stimulant use (i.e., cocaine and psychostimulants such as methamphetamine). We sought to characterize rates, presentation, and management of ED visits related to cocaine and psychostimulant use, compared to opioid use, in the United States (US).

METHODS

We used 2008-2018 National Hospital Ambulatory Medical Care Survey data to identify a nationally representative sample of ED visits related to cocaine and psychostimulant use, with opioids as the comparator. To make visits mutually exclusive for analysis, we excluded visits related to 2 or more of the three possible drug categories. We estimated annual rate trends using unadjusted Poisson regression; described demographics, presenting concerns, and management; and determined associations between drug-type and presenting concerns (categorized as psychiatric, neurologic, cardiopulmonary, and drug toxicity/withdrawal) using logistic regression, adjusting for age, sex, race/ethnicity, and homelessness.

RESULTS

Cocaine-related ED visits did not significantly increase, while psychostimulant-related ED visits increased from 2008 to 2018 (2.2 visits per 10,000 population to 12.9 visits per 10,000 population; p < 0.001). Cocaine-related ED visits had higher usage of cardiac testing, while psychostimulant-related ED visits had higher usage of chemical restraints than opioid-related ED visits. Cocaine- and psychostimulant-related ED visits had greater odds of presenting with cardiopulmonary concerns (cocaine adjusted odds ratio [aOR] 2.95, 95% CI 1.70-5.13; psychostimulant aOR 2.46, 95% CI 1.42-4.26), while psychostimulant-related visits had greater odds of presenting with psychiatric concerns (aOR 2.69, 95% CI 1.83-3.95) and lower odds of presenting with drug toxicity/withdrawal concerns (aOR 0.47, 95%CI 0.30-0.73) compared to opioid-related ED visits.

CONCLUSION

Presentations for stimulant-related ED visits differ from opioid-related ED visits: compared to opioids, ED presentations related to cocaine and psychostimulants are less often identified as related to drug toxicity/withdrawal and more often require interventions to address acute cardiopulmonary and psychiatric complications.

Perspectives of Stakeholders of Equitable Access to Community Naloxone Programs: A Literature Review

The purpose of this review is to examine the existing literature about facilitators and barriers influencing equitable access to naloxone programs by individuals who use opioids. A total of 49 published articles were examined, which generated four overarching themes:(1) Stigma as a barrier to access; (2) Lack of a wide range of stakeholder perspectives; (3) Need for a comprehensive understanding of factors affecting equitable access to naloxone programs; (4) Facilitators to increase the access of community naloxone programs. Our review highlighted the importance of advocacy in practice, education, administration, and policy to address the health inequities that exist in naloxone distribution programs. Advocacy activities involve the need for health care professionals to engage in social justice practice through evidence-based informed research about the facts of opioid use; challenging the stigma toward victim-blaming against naloxone users; as well as promoting program development and health policy to bring about equitable access to naloxone programs by marginalized and socially disadvantaged populations.

Predictors of having naloxone in urban and rural Oregon findings from NHBS and the OR-HOPE study

PURPOSE

Naloxone is an opioid antagonist that can be effectively administered by bystanders to prevent overdose. We determined the proportion of people who had naloxone and identified predictors of naloxone ownership among two samples of people who inject drugs (PWID) who use opioids in Portland and rural Western Oregon.

BASIC PROCEDURES

We used data from participants in Portland's National HIV Behavioral Surveillance (NHBS, N = 477) and the Oregon HIV/Hepatitis and Opioid Prevention and Engagement Study (OR-HOPE, N = 133). For each sample, we determined the proportion of participants who had naloxone and estimated unadjusted and adjusted relative risk of having naloxone associated with participant characteristics.

MAIN FINDINGS

Sixty one percent of NHBS and 30 % of OR-HOPE participants had naloxone. In adjusted analysis, having naloxone was associated with female gender, injecting goofballs (compared to heroin alone), housing stability, and overdose training in the urban NHBS sample, and having naloxone was associated with drug of choice, frequency of injection, and race in the rural OR-HOPE sample. In both samples, having naloxone was crudely associated with SSP use, but this was attenuated after adjustment.

PRINCIPAL CONCLUSIONS

Naloxone ownership was insufficient and highly variable among two samples of PWID who use opioids in Oregon. People who use methamphetamine, males, and people experiencing homelessness may be at increased risk for not having naloxone and SSP may play a key role in improving access.

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

BACKGROUND

Overdose 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).

METHODS

ETHOS 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.

RESULTS

Between 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.

CONCLUSIONS

Among 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.

Impact of the Opioid Epidemic

In recent years the prescription opioid overdose epidemic has decreased, but has been more than offset by increases in overdose caused by fentanyl and fentanyl analogues. Opioid overdose patients should receive naloxone if they have significant respiratory depression and/or loss of protective airway reflexes. Patients who receive naloxone should be observed for recurrent opioid effects. Patients with opioid overdose may be admitted to the intensive care unit for naloxone infusions, treatment of noncardiogenic pulmonary edema, autonomic instability, or sequelae of hypoxia-ischemia or cardiac arrest. Primary and secondary prevention are important to reduce the number of people with life-threatening opioid overdose.

Hospital policy as a harm reduction intervention for people who use drugs

Hospitals are a critical touchpoint for people who use drugs (PWUD). However, hospital policies, both formal and informal, can have a detrimental impact on PWUD in acute care settings. Introducing new policies, or revising existing policies that inadvertently harm or stigmatize PWUD while hospitalized, could be an effective harm reduction intervention for this high-risk population. This paper explores seven areas where institutional policy change could improve the hospital experience of PWUD: (1) use of nonprescribed substances in hospital, (2) supporting inpatient addiction consultation services (3) in-hospital supervised consumption spaces (4) supply and distribution of safe drug use equipment and naloxone, (5) role of security services and personal searches, (6) use of hospital restrictions, and (7) involvement of PWUD in policy development.

Take-home naloxone programs for suspected opioid overdose in community settings: a scoping umbrella review

BACKGROUND

Opioid related overdoses and overdose deaths continue to constitute an urgent public health crisis. The implementation of naloxone programs, such as 'take-home naloxone' (THN), has emerged as a key intervention in reducing opioid overdose deaths. These programs aim to train individuals at risk of witnessing or experiencing an opioid overdose to recognize an opioid overdose and respond with naloxone. Naloxone effectively reverses opioid overdoses on a physiological level; however, there are outstanding questions on community THN program effectiveness (adverse events, dosing requirements, dose-response between routes of administration) and implementation (accessibility, availability, and affordability). The objective of this scoping review is to identify existing systematic reviews and best practice guidelines relevant to clinical and operational guidance on the distribution of THN.

METHODS

Using the Arksey & O'Malley framework for scoping reviews, we searched both academic literature and grey literature databases using keywords (Naloxone) AND (Overdose) AND (Guideline OR Review OR Recommendation OR Toolkit). Only documents which had a structured review of evidence and/or provided summaries or recommendations based on evidence were included (systematic reviews, meta-analyses, scoping reviews, short-cut or rapid reviews, practice/clinical guidelines, and reports). Data were extracted from selected evidence in two key areas: (1) study identifiers; and (2) methodological characteristics.

RESULTS

A total of 47 articles met inclusion criteria: 20 systematic reviews; 10 grey literature articles; 8 short-cut or rapid reviews; 4 scoping reviews; and 5 other review types (e.g. mapping review and comprehensive reviews). The most common subject themes were: naloxone effectiveness, safety, provision feasibility/acceptability of naloxone distribution, dosing and routes of administration, overdose response after naloxone administration, cost-effectiveness, naloxone training and education, and recommendations for policy, practice and gaps in knowledge.

CONCLUSIONS

Several recent systematic reviews address the effectiveness of take-home naloxone programs, naloxone dosing/route of administration, and naloxone provision models. Gaps remain in the evidence around evaluating cost-effectiveness, training parameters and strategies, and adverse events following naloxone administration. As THN programs continue to expand in response to opioid overdose deaths, this review will contribute to understanding the evidence base for policy and THN program development and expansion.

Increasing Naloxone Prescribing in the Emergency Department Through Education and Electronic Medical Record Work-Aids

BACKGROUND

Emergency department (ED) visits for opioid overdose continue to rise. Evidence-based harm reduction strategies for opioid use disorder (OUD), such as providing home naloxone, can save lives, but ED implementation remains challenging.

METHODS

The researchers aimed to increase prescribing of naloxone to ED patients with OUD and opioid overdose by employing a model for improvement methodology, a multidisciplinary team, and high-reliability interventions. Monthly naloxone prescribing rates among discharged ED patients with opioid overdose and OUD-related diagnoses were tracked over time. Interventions included focused ED staff education on OUD and naloxone, and creation of electronic medical record (EMR)-based work-aids, including a naloxone Best Practice Advisory (BPA) and order set. Autoregressive interrupted time series was used to model the impact of these interventions on naloxone prescribing rates. The impact of education on ED staff confidence and perceived barriers to prescribing naloxone was measured using a published survey instrument.

RESULTS

After adjusting for education events and temporal trends, ED naloxone BPA and order set implementation was associated with a significant immediate 21.1% increase in naloxone prescribing rates, which was sustained for one year. This corresponded to increased average monthly prescribing rates from 1.5% before any intervention to 28.7% afterward. ED staff education had no measurable impact on prescribing rates but was associated with increased nursing perceived importance and increased provider confidence in prescribing naloxone.

CONCLUSIONS

A significant increase in naloxone prescribing rates was achieved after implementation of high-reliability EMR work-aids and staff education. Similar interventions may be key to wider ED staff engagement in harm reduction for patients with OUD.

Adult emergency department naloxone education and prescription program: Video and pamphlet education comparison

OBJECTIVES

This study looked at the fill rate of naloxone prescriptions, after the implementation of an opioid overdose and naloxone education intervention for adult patients in the emergency department (ED). The study compared fill rates between recipients who received this education by video versus written format.

METHODS

This was a prospective, randomized controlled study of patients seen in the adult ED for opioid-related complaints between August 1, 2017, and December 1, 2018. The study randomized patients to education through video or written pamphlet, and all patients received a prescription for a free naloxone kit redeemable at the discharge pharmacy. The study calculated and compared naloxone prescription fill rates for the respective education methods.

RESULTS

Of the 770 patients reviewed for recruitment, the study excluded 703. Of the 67 patients enrolled, 59 were contacted at follow-up and eighteen (30.5%) had filled a naloxone prescription. Thirty-three percent (13/39) of patients who received video education and 25% (5/20) who received written pamphlet education filled naloxone prescriptions. The p-value of the chi-square for this data was 0.53.

CONCLUSIONS

There is a large population affected by opioid overdose both nationally and locally in Arizona. Opioid overdose and naloxone distribution education for ED patients through both video and pamphlet is feasible but requires more research to determine which education method is superior. Legislative changes, improved identification of patients at high risk for opioid overdose, opiate education for medical providers, and naloxone availability from multiple venues are needed to create a holistic approach to improve naloxone access to those who need it most.

Death after emergency department visits for opioid overdose in British Columbia: a retrospective cohort analysis

BACKGROUND

Visits to the emergency department are critical opportunities to engage individuals after an overdose. We sought to estimate and compare the 12-month mortality between persons with visits to the emergency department related to opioid overdose and those with non-overdose-related visits.

METHODS

We conducted a retrospective cohort study using the Provincial Overdose Cohort, which contains data for patients in British Columbia who had an opioid-related overdose between 2015 and 2017, along with a 20% random sample of BC residents for comparison. We examined all nonfatal visits to the emergency department between Jan. 1, 2015, and Dec. 31, 2016, among persons aged 14 to 74 years and compared the 12-month mortality between those with overdose-related visits and those with non-overdose-related visits. We estimated the hazard ratio for death, with adjustment for age, sex, comorbidity and disposition (discharged or left against medical advice).

RESULTS

We included 3593 persons with overdose-related visits and 216 453 with non-overdose-related visits to the emergency department. Those with overdose-related visits were younger, were predominantly male and had more mental health conditions. The 12-month crude mortality probability was 5.4% (95% confidence interval [CI] 4.7%-6.2%) in this group and 1.7% (95% CI 1.6%-1.8%) among those with non-overdose-related visits. After adjustment, for persons who were discharged, the 12-month mortality hazard was 3.5 (95% CI 3.0-4.2) times higher among those with overdose-related visits than those with non-overdose-related visits. For persons who left against medical advice, the mortality hazard was 7.1 (95% CI 4.0-12.5) times higher among those with opioid overdose.

INTERPRETATION

Among persons with overdose-related visits to the emergency department, 12-month mortality was higher than among those with non-overdose-related visits. Overdose-related visits should prompt urgent evidence-based interventions (e.g., take-home naloxone kits, buprenorphine-naloxone induction) to prevent future deaths.

The Opioid-overdose Reduction Continuum of Care Approach (ORCCA): Evidence-based practices in the HEALing Communities Study

BACKGROUND

The number of opioid-involved overdose deaths in the United States remains a national crisis. The HEALing Communities Study (HCS) will test whether Communities That HEAL (CTH), a community-engaged intervention, can decrease opioid-involved deaths in intervention communities (n = 33), relative to wait-list communities (n = 34), from four states. The CTH intervention seeks to facilitate widespread implementation of three evidence-based practices (EBPs) with the potential to reduce opioid-involved overdose fatalities: overdose education and naloxone distribution (OEND), effective delivery of medication for opioid use disorder (MOUD), and safer opioid analgesic prescribing. A key challenge was delineating an EBP implementation approach useful for all HCS communities.

METHODS

A workgroup composed of EBP experts from HCS research sites used literature reviews and expert consensus to: 1) compile strategies and associated resources for implementing EBPs primarily targeting individuals 18 and older; and 2) determine allowable community flexibility in EBP implementation. The workgroup developed the Opioid-overdose Reduction Continuum of Care Approach (ORCCA) to organize EBP strategies and resources to facilitate EBP implementation.

CONCLUSIONS

The ORCCA includes required and recommended EBP strategies, priority populations, and community settings. Each EBP has a "menu" of strategies from which communities can select and implement with a minimum of five strategies required: one for OEND, three for MOUD, and one for prescription opioid safety. Identification and engagement of high-risk populations in OEND and MOUD is an ORCCArequirement. To ensure CTH has community-wide impact, implementation of at least one EBP strategy is required in healthcare, behavioral health, and criminal justice settings, with communities identifying particular organizations to engage in HCS-facilitated EBP implementation.

Naloxone provision to emergency department patients recognized as high-risk for opioid use disorder

INTRODUCTION

Patients with opioid use disorder (OUD) are at increased risk for overdose and death. Clinical practice guidelines and professional organization policy statements recommend providing naloxone to patients at risk for overdose. We sought to characterize fidelity to naloxone practice recommendations in a cohort of Emergency Department (ED) patients in whom opioid use disorder was suspected by the treating physician.

METHODS

This single-center cross-sectional study evaluated electronic health records from an urban academic ED with 73,000 annual encounters in a region with a high prevalence of OUD. Patients ≥18 years old with encounters from January 1, 2018 to November 30, 2019 were included if discharged from the ED and either administered buprenorphine in the ED or referred to outpatient substance use treatment. The primary outcome measure was the percentage of included patients provided naloxone (take-home or prescription). We used random effects multivariable logistic regression (accounting for multiple patient encounters) to estimate the odds ratio (OR) for receiving naloxone.

RESULTS

Of 1036 eligible patient encounters, 320 resulted in naloxone provision (30.9%, 95% CI: 28.1-33.8). Naloxone provision occurred for 33.6% (95% CI 30.5-36.7) of 900 patients referred to outpatient substance use treatment without ED buprenorphine administration, 10.6% (95% CI 5.0-19.2) of 85 patients administered buprenorphine and not referred to outpatient substance use treatment, and 17.6% (95% CI 8.4-30.9) of 51 patients administered buprenorphine and referred to outpatient treatment. After controlling for age, sex, race, and prior provision of naloxone, the administration of buprenorphine was associated with a 94% lower odds (aOR = 0.06 [95% CI 0.011-0.33]) for naloxone provision compared to those only referred to outpatient treatment.

CONCLUSION

A majority of ED patients who received an intervention targeted at OUD, in an ED where take-home naloxone is freely available, did not receive either take-home naloxone or a prescription for naloxone at discharge. Patients receiving buprenorphine were less likely to receive naloxone than patients only referred to outpatient treatment. These data suggest barriers other than recognition of potential OUD and naloxone availability impact provision of naloxone and argue for a treatment "bundle" as a conceptual model for care of ED patients with suspected OUD.

Prescribing Buprenorphine for Opioid Use Disorders in the ED: A Review of Best Practices, Barriers, and Future Directions

ED-initiated addiction treatment holds promise for enhancing access to treatment for those with opioid use disorder (OUD). We present a literature review summarizing the evidence for buprenorphine induction in the ED including best practices for dosing, follow-up care, and reducing implementation barriers. A literature search of Pubmed, PsychInfo, and Embase identified articles studying OUD treatment in the ED published after 1980. Twenty-five studies were identified including eleven scientific abstracts. Multiple studies suggest that buprenorphine induction improves engagement in substance treatment up to 30 days after ED treatment. Many different induction protocols were presented, but no particular approach was best supported as criteria for induction and initial dosing vary widely. Similarly, transition of care models focused on either a "hub and spoke" model or "warm hand-offs" model, but no studies compared these approaches. Common barriers to implementing induction programs were provider inexperience, discomfort with addiction treatment, and limited time during the ED visit. No studies described the number of EDs offering induction. While ED buprenorphine induction is safe and enhances adherence to addiction treatment, uncertainty persists in how to best identify patients needing treatment, how to initiate buprenorphine, and how to enhance follow-up after ED-initiated treatment.

Facilitators, barriers and lessons learnt from the first state-wide naloxone distribution conducted in West Virginia

BACKGROUND

Overdose education and naloxone distribution programmes are known to reduce opioid-related deaths. A state-wide naloxone distribution effort of 8250 rescue kits was undertaken by government, community and university partners in West Virginia in 2016-2017. The purpose of this study was to discern the barriers, facilitators and lesson learnt from implementing this endeavour in a rural state with the highest opioid overdose fatality rate in the US.

METHODS

Structured interviews (n=26) were conducted among both internal and external stakeholders. Those who participated were >18 years of age and were the lead representative from agencies that either received naloxone (ie, external stakeholders) or helped implement the distribution (ie, internal stakeholders). The interviews followed standardised scripts and lasted approximately 40 min. Sessions were audio-recorded and transcribed. Qualitative content analysis was performed by two researchers to determine themes surrounding facilitators or barriers to programme implementation.

RESULTS

The primary facilitators reported by stakeholders included collaborative partnerships, ease of participating in the programme, being established in prevention efforts, demand for naloxone and the need for personal protection from overdose. The primary barriers identified by stakeholders included bureaucracy/policy/procedures of their organisation or agency, stigma, logistical or planning issues, problems with reporting, lack of communication post distribution and sustainability. Numerous lessons were learnt.

CONCLUSIONS

Based on the implementation of the programme in 87 organisations, including law enforcement and fire departments, the impact of facilitators outweighed that of barriers. These findings may inform others planning to conduct a similar, large-scale project.

Point-of-sale Naloxone: Novel Community-based Research to Identify Naloxone Availability

Introduction

Expanding naloxone availability is important to reduce opioid-related deaths. Recent data suggest low, variable urban naloxone availability. No reports describe naloxone availability at the point of sale (POSN). We characterize POSN without prescription across a Midwestern metropolitan area, via a unique poison center-based study.

Methods

Pharmacies were randomly sampled within a seven-county metropolitan area, geospatially mapped, and distributed among seven investigators, who visited pharmacies and asked, “May I purchase naloxone here without a prescription from my doctor?” Following “No,” investigators asked, “Are you aware of the state statute that allows you to dispense naloxone to the public under a standing order?” Materials describing statutory support for POSN were provided. Responses were uploaded to REDCap in real time. We excluded specialty (veterinary, mail order, or infusion) pharmacies a priori. POSN availability is presented as descriptive statistics; characteristics of individual sites associated with POSN availability are reported.

Results

In total, 150 pharmacies were prospectively randomized, with 52 subsequently excluded or unavailable for survey. Thus, 98 were included in the final analysis. POSN was available at 71 (72.5%) of 98 pharmacies. POSN availability was more likely at chain than independent pharmacies (84.7% vs 38.5%, p<0.001); rural areas were more commonly served by independent than chain pharmacies (47.4% vs 21.5%, p = 0.022). Five chain and five independent pharmacies (18.5% each) were unaware of state statutory support for collaborative POSN agreements. Statutory awareness was similar between independent and chain pharmacies (68.8% vs 54.6%, p = 0.453). Rationale for no POSN varied.

Conclusion

POSN is widely available in this metropolitan area. Variability exists between chain and independent pharmacies, and among pharmacies of the same chain; awareness of statutory guidance does not. Poison centers can act to define local POSN availability via direct inquiry in their communities.

Interrupted Time Series of User-centered Clinical Decision Support Implementation for Emergency Department-initiated Buprenorphine for Opioid Use Disorder

OBJECTIVES

Adoption of emergency department (ED) initiation of buprenorphine (BUP) for opioid use disorder (OUD) into routine emergency care has been slow, partly due to clinicians' unfamiliarity with this practice and perceptions that it is complicated and time-consuming. To address these barriers and guide emergency clinicians through the process of BUP initiation, we implemented a user-centered computerized clinical decision support system (CDS). This study was conducted to assess the feasibility of implementation and to evaluate the preliminary efficacy of the intervention to increase the rate of ED-initiated BUP.

METHODS

An interrupted time series study was conducted in an urban, academic ED from April 2018 to February 2019 (preimplementation phase), March 2019 to August 2019 (implementation phase), and September 2019 to December 2019 (maintenance phase) to study the effect of the intervention on adult ED patients identified by a validated electronic health record (EHR)-based computable phenotype consisting of structured data consistent with potential cases of OUD who would benefit from BUP treatment. The intervention offers flexible CDS for identification of OUD, assessment of opioid withdrawal, and motivation of readiness to start treatment and automates EHR activities related to ED initiation of BUP (including documentation, orders, prescribing, and referral). The primary outcome was the rate of ED-initiated BUP. Secondary outcomes were launch of the intervention, prescription for naloxone at ED discharge, and referral for ongoing addiction treatment.

RESULTS

Of the 141,041 unique patients presenting to the ED over the preimplementation and implementation phases (i.e., the phases used in primary analysis), 906 (574 preimplementation and 332 implementation) met OUD phenotype and inclusion criteria. The rate of BUP initiation increased from 3.5% (20/574) in the preimplementation phase to 6.6% (22/332) in the implementation phase (p = 0.03). After the temporal trend of the number of physician's with X-waiver training and other covariates were adjusted for, the relative risk of BUP initiation rate was 2.73 (95% confidence interval [CI] = 0.62 to 12.0, p = 0.18). Similarly, the number of unique attendings who initiated BUP increased modestly 7/53 (13.0%) to 13/57 (22.8%, p = 0.10) after offering just-in-time training during the implementation period. The rate of naloxone prescribed at discharge also increased (6.5% preimplementation and 11.5% implementation; p < 0.01). The intervention received a system usability scale score of 82.0 (95% CI = 76.7 to 87.2).

CONCLUSION

Implementation of user-centered CDS at a single ED was feasible, acceptable, and associated with increased rates of ED-initiated BUP and naloxone prescribing in patients with OUD and a doubling of the number of unique physicians adopting the practice. We have implemented this intervention across several health systems in an ongoing trial to assess its effectiveness, scalability, and generalizability.

Best Practices for a Novel EMS-Based Naloxone Leave behind Program

BACKGROUND

Increasing naloxone access has been identified as a primary strategy to reduce opioid overdose deaths. To supplement community naloxone training and distribution access points, EMS systems have instituted public safety-based naloxone leave behind (NLB) programs that allow emergency medical responders to distribute "leave behind" naloxone kits on the scene of an overdose. This model presents an opportunity to expand naloxone access for individuals at high risk for future overdoses. Objectives: To evaluate the preliminary outcomes of a novel EMS-based NLB program in Howard County, Maryland. Methods: This exploratory study involved analysis of data from the Howard County NLB Program. Basic statistical analysis of program performance metrics and participant demographic characteristics were performed. Results: From June 2018 to June 2019, Howard County Department of Fire and Rescue Services responded to 239 overdose calls and distributed 120 naloxone kits to individuals on the scene of an overdose, a 50.21% distribution rate. The HCNLB program connected 143 patients (59.83%) to peer recovery specialists. Among the 143 patients linked to peer recovery support specialist services, 87 (60.84%) had accepted an NLB kit from EMS. The fully adjusted logistic regression model revealed that those whose kit was left with a family member on the scene were 5.16 times more likely to be connected to peer support specialists (OR = 5.16, CI= 2.35 - 11.29, p = 0.000) while those whose kit was left with a friend or given directly to the patient were 3.69 times (OR = 3.69, CI= 1.13 - 12.06, p < 0.05) and 2.37 times (OR = 2.37, CI= 1.10 - 5.14, p < 0.05) more likely, respectively, to be connected to follow up services as compared to those who did not accept a kit, controlling for other variables in the model. Conclusion: This study highlights the importance of engaging an individual's family and social network when offering connections to treatment and recovery resources. NLB initiatives can potentially augment existing community-based naloxone training structures, thus widening the scope of the life-saving drug and reaching those most at risk of dying from an opioid overdose.

Change in opioid policies in New England emergency departments, 2014 vs 2018

OBJECTIVE

The U.S. opioid epidemic persists, yet it is unclear if opioid-related emergency department (ED) policies have changed. We investigated: 1) the prevalence of opioid use disorder (OUD) prevention and treatment policies in New England EDs in 2018, and 2) how these policies have changed since 2014.

METHODS

Using the National Emergency Department Inventory-USA, we identified and surveyed all New England EDs in 2015 and 2019 about opioid-related policies in 2014 and 2018, respectively. The surveys assessed OUD prevention policies (to use a screening tool, access the Prescription Drug Monitoring Program [PDMP], notify primary care providers, prescribe/dispense naloxone) and treatment policies (to refer to recovery resources, prescribe/dispense buprenorphine).

RESULTS

Of 194 EDs open in 2018, 167 (86 %) completed the survey. Of 193 EDs open in 2018 and 2014, 147 (76 %) completed both surveys. In 2018, the most commonly-reported policy was accessing the PDMP (96 %); the least commonly-reported policy was prescribing/dispensing buprenorphine to at risk patients (37 %). EDs varied in prescribing/dispensing naloxone: 35 % of EDs offered naloxone to ≥80 % of patients at risk of opioid overdose versus 33 % of EDs to <10 % of patients at risk. Most EDs (74 %) reported prescribing/dispensing buprenorphine to <10 % of patients with OUD. Comparing 2018 to 2014, the greatest difference in policy use was in prescribing/dispensing naloxone (+55 %, p < 0.001).

CONCLUSION

Implementation of opioid-related ED policies increased between 2014 and 2018. Continued effort is needed to understand the extent to which policy implementation translates to clinical care, and to best translate evidence-based policies into clinical practice.

Access and Barriers to Take-Home Naloxone Use among Emergency Department Patients with Opioid Misuse in Baltimore, Maryland, USA

The opioid epidemic has prompted the expansion of take-home naloxone (THN) distribution programs. The proportion of emergency department (ED) patients with opioid misuse who have access to a naloxone kit (NK) and barriers to using it are unclear. Objective: Characterizing the access and barrier to NK use among at-risk ED patients. Methods: We enrolled a convenience sample of ED patients with active opioid misuse from May 21-July 31, 2018. We administered a survey to collect patients' demographic data, substance use history, and access to and use of NK. The primary outcome was NK access (prior receipt of a kit or prescription); secondary outcomes were knowledge and use of NK, and barriers to obtaining and using it. Results: Of 165 respondents, 71.5% knew of THN programs and 57.6% (n = 95) had access to THN by either having received a NK (n = 90) or a prescription (n = 5); 34 respondents received both. Among 39 (23.6%) who received a naloxone prescription, 25 (64.1%) filled it. 60.0% (n = 99) reported knowing how to administer naloxone; lack of training was the primary reason (n = 63/66, 96.9%) for their unfamiliarity. Patients who presented after an opioid overdose (25.5%; n = 42) were less likely to have knowledge of THN programs (57.1% vs. 76.4%), and to have received a NK (35.7% vs. 61.0%). Conclusion: Awareness of THN programs was high among our cohort. But approximately 60% the respondents received a NK or knew how to use it. Despite efforts to expand THN access, gaps in knowledge, access, and use exist.
