Attitudes Toward Naloxone Prescribing in Clinical Settings: A Qualitative Study of Patients Prescribed High Dose Opioids for Chronic Non-Cancer Pain

Naloxone co-prescriptions for surgery patients prescribed opioids: A retrospective cohort study

Background

Surgeon-prescribed opioids contribute to 11% of prescription drug overdoses in the United States (US). With prescription opioids involved in 24% of all opioid-related overdose deaths in 2020, the US Centers for Disease Control and Prevention (CDC) recommends naloxone co-prescribing to patients at high-risk of overdose and death as a harm reduction strategy. We sought to 1) examine naloxone co-prescribing rates to surgical patients (using common post-surgical prescribing amounts) and those with potential risk factors for opioid-related overdoses or adverse events, and 2) identify the factors associated with patients receiving naloxone co-prescriptions.

Methods

We conducted a single-institution, retrospective study using the electronic medical records of all patients undergoing surgery at an academic institution between August 2020 and May 2021. We included post-surgical adults prescribed opioids that were sent to a pharmacy in our health system. The primary outcome was the percentage of co-prescribed naloxone in patients prescribed opioids.

Results

The overall naloxone co-prescription rate was low (1.7%). Only 14.6% of patients prescribed ≥350 morphine milligram equivalents (MME, equivalent to 46.7 oxycodone 5 mg tablets) and 8.6% of patients using illicit drugs were co-prescribed naloxone. On multivariable analysis, patients who were prescribed >350 MME, used illicit drugs or tobacco, underwent an elective or emergent general surgery procedure, self-identified as Hispanic, or had ASA scores of 2-4 were more likely to receive a naloxone co-prescription.

Conclusions

Naloxone co-prescribing after surgery remains low, even for high-risk patients. Harm reduction strategies such as naloxone, safe storage, and disposal of leftover opioids could reduce surgeons' iatrogenic contributions to the worsening US opioid crisis.

Naloxone analogy and opioid overdose terminology preferences among rural caregivers: Differences by race

BACKGROUND

Despite national and state policies aimed at increasing naloxone access via pharmacies, opioid overdose death rates rose during the COVID-19 pandemic, particularly among Blacks and American Indians (AIs) in rural areas. Caregivers, or third parties who can administer naloxone during an overdose event, are important individuals in the naloxone administration cascade, yet no studies have explored rural caregivers' opioid overdose terminology and naloxone analogy preferences or whether these preferences differ by race.

OBJECTIVES

To identify rural caregivers' overdose terminology and naloxone analogy preferences and determine whether preferences differ by race.

METHODS

A sample of 40 caregivers who lived with someone at high risk of overdose and used pharmacies in 4 largely rural states was recruited. Each caregiver completed a demographic survey and a 20- to 45-minute audio-recorded semi-structured interview that was transcribed, de-identified, and imported into a qualitative software package for thematic analysis by 2 independent coders using a codebook. Overdose terminology and naloxone analogy preferences were analyzed for differences by race.

RESULTS

The sample was 57.5% white, 35% Black, and 7.5% AIs. Many participants (43%) preferred that pharmacists use the term "bad reaction" to refer to overdose events over the terms "accidental overdose" (37%) and "overdose" (20%). The majority of white and Black participants preferred "bad reaction" while AI participants preferred "accidental overdose." For naloxone analogies, "EpiPen" was most preferred (64%), regardless of race. "Fire extinguisher" (17%), "lifesaver" (9.5%), and other analogies (9.5%) were preferred by some white and Black participants but not AI participants.

CONCLUSION

Our findings suggest that pharmacists should use the "bad reaction" term and "EpiPen" analogy when counseling rural caregivers about overdose and naloxone, respectively. Caregivers' preferences varied by race, suggesting that pharmacists may want to tailor the terminology and analogy they use when discussing naloxone with caregivers.

Prescribe to Save Lives: An Intervention to Increase Naloxone Prescribing Among HIV Clinicians

OBJECTIVES

Overdose is a major cause of preventable death among persons living with HIV. This study aimed to increase HIV clinicians' naloxone prescribing, which can reduce overdose mortality.

METHODS

We enrolled 22 Ryan White-funded HIV practices and implemented onsite, peer-to-peer training, posttraining academic detailing, and pharmacy peer-to-peer contact around naloxone prescribing in a nonrandomized stepped wedge design. Human immunodeficiency virus clinicians completed surveys to assess attitudes toward prescribing naloxone at preintervention and 6 and 12 months postintervention. Aggregated electronic health record data measured the number of patients with HIV prescribed and the number of HIV clinicians prescribing naloxone by site over the study period. Models controlled for calendar time and clustering of repeated measures among individuals and sites.

RESULTS

Of 122 clinicians, 119 (98%) completed a baseline survey, 111 (91%) a 6-month survey, and 93 (76%) a 12-month survey. The intervention was associated with increases in self-reported "high likelihood" to prescribe naloxone (odds ratio [OR], 4.1 [1.7-9.4]; P = 0.001). Of 22 sites, 18 (82%) provided usable electronic health record data that demonstrated a postintervention increase in the total number of clinicians who prescribed naloxone (incidence rate ratio, 2.9 [1.1-7.6]; P = 0.03) and no significant effects on sites having at least one clinician who prescribed naloxone (OR, 4.1 [0.7-23.8]; P = 0.11). The overall proportion of all HIV patients prescribed naloxone modestly increased from 0.97% to 1.6% (OR, 2.2 [0.7-6.8]; P = 0.16).

CONCLUSION

On-site, practice-based, peer-to-peer training with posttraining academic detailing was a modestly effective strategy to increase HIV clinicians' prescribing of naloxone.

Standard Naloxone Prescribing for Palliative Care Cancer Patients on Opioid Therapy: A Single-Site Quality Improvement Pilot to Assess Attitudes and Access

BACKGROUND

Limited data exist on when to offer naloxone to cancer patients on opioid therapy.

MEASURES

We assessed patient and clinician attitudes on naloxone education (done via surveys at initial and follow up visits) and prescribing rates (via chart reviews) at a single ambulatory palliative care practice. Pharmacy records assessed naloxone dispense rates.

INTERVENTION

During a three-month period, all new patients receiving opioid therapy were offered naloxone. Standardized educational materials on opioid safety and naloxone use were created and shared by clinical team.

OUTCOMES

Naloxone prescribing rates increased from 5% to 66%. 92% (n = 23) of clinicians reported education/prescribing took ≤ five minutes, and 100% reported either a positive or neutral impact on the encounter. A total of 81% (n = 25) of patients reported no increased worry about opioid use, 68% (n = 21) felt safer with naloxone, and 97% rated the encounter as neutral or positive. 88% (n = 37) of prescriptions were dispensed and 67% of patients (n = 16) paid <$10.

CONCLUSIONS/LESSONS LEARNED

Opioid safety education and naloxone prescribing can be done quickly and is well-received by clinicians and patients.

Patient, family members and community pharmacists' views of a proposed overdose prevention intervention delivered in community pharmacies for patients prescribed high-strength opioids for chronic non-cancer pain: An explorative intervention development study

INTRODUCTION

Despite opioid prescribing for chronic non-cancer pain (CNCP) having limited therapeutic benefits, recent evidence indicates significant increases in the prescribing of high-strength opioids for individuals with CNCP. Patients prescribed opioids for CNCP have overdose risk factors but generally have low opioid overdose awareness and low perceptions of risk related to prescribed opioids. Currently, there are few bespoke overdose prevention resources for this group.

METHODS

This qualitative study investigated views on a naloxone intervention for people prescribed high-strength opioids for CNCP delivered via community pharmacies. The intervention included overdose risk awareness and naloxone training and provision. Interviews were conducted with eight patients, four family members and two community pharmacists. Participants were convenience sampled and recruited through networks within the Scottish pain community. The Framework approach was used to analyse findings.

RESULTS

All participants had positive attitudes towards the intervention, but patients and family members considered risk of overdose to be very low. Three themes were identified: potential advantages of the intervention; potential barriers to the intervention; and additional suggestions and feedback about the intervention. Advantages included the intervention providing essential overdose information for CNCP patients. Barriers included resource and time pressures within community pharmacies.

DISCUSSION AND CONCLUSION

While patients had low overdose knowledge and did not see themselves as being at risk of opioid overdose, they were receptive to naloxone use and positive about the proposed intervention. A feasibility trial is merited to further investigate how the intervention would be experienced within community pharmacy settings.

Pharmacists' naloxone services beyond community pharmacy settings: A systematic review

BACKGROUND

Pharmacists' provision of naloxone services in community pharmacy settings is well-recognized. Recently, studies describing pharmacists' naloxone services in settings other than community pharmacies have emerged in the literature. There is a need to synthesize evidence from these studies to evaluate the scope and impact of pharmacists' naloxone services beyond community pharmacy settings.

OBJECTIVES

The objectives of this systematic review were to a) identify pharmacists' naloxone services and their outcomes, and b) examine knowledge, attitudes, and barriers (KAB) related to naloxone service provision in non-community pharmacy settings.

METHODS

Eligible studies were identified using PubMed, Web of Science, and CINAHL. Inclusion criteria were as follows: peer-reviewed empirical research conducted in the U.S. from January 2010 through February 2022; published in English; and addressed a) pharmacists' naloxone services and/or b) KAB related to the implementation of naloxone services. PRISMA guidelines were used to report this study.

RESULTS

Seventy-six studies were identified. The majority were non-randomized and observational; only two used a randomized controlled (RCT) design. Most studies were conducted in veterans affairs (30%) and academic medical centers (21%). Sample sizes ranged from n = 10 to 217,469, and the majority reported sample sizes <100. Pharmacists' naloxone services involved clinical staff education, utilization of screening tools to identify at-risk patients, naloxone prescribing and overdose education and naloxone dispensing (OEND). Outcomes of implementing naloxone services included improved naloxone knowledge, positive attitudes, increased OEND, and overdose reversals. Pharmacists cited inadequate training, time constraints, reimbursement issues, and stigma as barriers that hindered naloxone service implementation.

CONCLUSION

This systematic review found robust evidence regarding pharmacist-based naloxone services beyond community pharmacy settings. Future programs should use targeted approaches to help pharmacists overcome barriers and enhance naloxone services. Additional research is needed to evaluate pharmacist naloxone services by using rigorous methodologies (e.g., larger sample sizes, RCT designs).

Addressing the opioid epidemic through community pharmacy engagement: Study protocol for a randomized controlled trial

BACKGROUND

Despite the authority to dispense naloxone, pharmacists have been reluctant to offer and dispense it, often due to discomfort communicating about the sensitive topic of opioid overdose. Because existing online naloxone trainings do not sufficiently address how to communicate effectively with patients about naloxone, Nalox-Comm, a training module designed to improve pharmacists' self-efficacy to engage in naloxone discussions, was developed.

OBJECTIVE

To describe the study protocol to evaluate the effectiveness of the Nalox-Comm training module on naloxone dispensing rates.

METHODS

A randomized controlled trial, which began in July 2021, is used to evaluate the pre-post Nalox-Comm training intervention. Sixty pharmacists are being recruited from 62 pharmacies part of a single grocery store chain in rural counties of the southeastern United States. After completing a baseline survey, pharmacists are observed by simulated patients (SPs) who rate the quality of their pre-training naloxone communication. Pharmacists are then invited to complete either a basic online naloxone training module (control group) or a newly developed Nalox-Comm training (experimental group), after which they complete a post-training survey and are observed a second time by SPs. Three months post-training, study participants complete a final follow-up survey. Naloxone dispensing records are obtained from each participating pharmacy to assess change in naloxone dispensing rates.

CONCLUSION

Informed by rural pharmacist stakeholders, the Nalox-Comm training module addresses communication barriers specific to rural communities. Compared to those in the control group, we hypothesize that pharmacies in the experimental group will dispense more naloxone in the three months post-training intervention.

Intention to get naloxone among patients prescribed opioids for chronic pain

BACKGROUND

Prescription opioids have been increasingly prescribed for chronic pain while the opioid-related death rates grow. Naloxone, an opioid antagonist, is increasingly recommended in these patients, yet there is limited research that investigates the intention to get naloxone. This study aimed to investigate intention toward getting naloxone in patients prescribed opioids for chronic pain and to assess the predictive utility of the theory of reasoned action (TRA) constructs in explaining intention to get naloxone.

METHODS

This was a cross-sectional study of a panel of U.S. adult patients prescribed opioids for chronic pain using a Qualtrics_®^XM survey. These patients participated in the study during February to March 2020. The online internet survey assessed the main outcome of intention to get naloxone and constructs of TRA (attitudes and subjective norms); additional measures assessed the characteristics of patients' opioid overdose risk factors, knowledge of naloxone, and their demographics. The relationship between TRA constructs, namely, attitudes and subjective norms, and the intention variable was examined using logistic regression analyses with the intention outcome contrasted as follows: high intention (scores ≥ 5) and non-high intention (scores < 5).

RESULTS

A total of 549 participants completed the survey. Most of them were female (53.01%), White or Caucasian (83.61%), non-Hispanic (87.57%) and had a mean age of 44.16 years (SD = 13.37). Of these, 167 (30.42%) had high intention to get naloxone. The TRA construct of subjective norm was significantly associated with increased likelihood of higher intentions to get naloxone (OR 3.04, 95% CI 2.50-3.70, P < 0.0001).

CONCLUSIONS

Our study provides empirical support of the TRA in predicting intention to get naloxone among chronic pain patients currently taking opioids. Subjective norms significantly predicted intention to get naloxone in these patients. The interventions targeting important reference groups of these patients would have greater impact on increasing intention to get naloxone in this population. Future studies should test whether theory-based interventions focusing on strengthening subjective norms increase intention to get naloxone in this population.

Patient perspectives on naloxone receipt in the emergency department: a qualitative exploration

Background

Emergency departments (EDs) are important venues for the distribution of naloxone to patients at high risk of opioid overdose, but less is known about patient perceptions on naloxone or best practices for patient education and communication. Our aim was to conduct an in-depth exploration of knowledge and attitudes toward ED naloxone distribution among patients who received a naloxone prescription.

Methods

We conducted semi-structured telephone interviews with 25 adult participants seen and discharged from three urban, academic EDs in Philadelphia, PA, with a naloxone prescription between November 2020 and February 2021. Interviews focused on awareness of naloxone as well as attitudes and experiences receiving naloxone in the ED. We used thematic content analysis to identify key themes reflecting patient attitudes and experiences.

Results

Of the 25 participants, 72% had previously witnessed an overdose and 48% had personally experienced a non-fatal overdose. Nineteen participants (76%) self-disclosed a history of substance use or overdose, and one reported receiving an opioid prescription during their ED visit and no history of substance use. In interviews, we identified wide variability in participant levels of knowledge about overdose risk, the role of naloxone in reducing risk, and naloxone access. A subset of participants was highly engaged with community harm reduction resources and well versed in naloxone access and use. A second subset was familiar with naloxone, but largely obtained it through healthcare settings such as the ED, while a final group was largely unfamiliar with naloxone. While most participants expressed positive attitudes about receiving naloxone from the ED, the quality of discussions with ED providers was variable, with some participants not even aware they were receiving a naloxone prescription until discharge.

Conclusions

Naloxone prescribing in the ED was acceptable and valued by most participants, but there are missed opportunities for communication and education. These findings underscore the critical role that EDs play in mitigating risks for patients who are not engaged with other healthcare or community health providers and can inform future work about the effective implementation of harm reduction strategies in ED settings.

Naloxone Co-Dispensing with Opioids: a Cluster Randomized Pragmatic Trial

BACKGROUND

Although naloxone prevents opioid overdose deaths, few patients prescribed opioids receive naloxone, limiting its effectiveness in real-world settings. Barriers to naloxone prescribing include concerns that naloxone could increase risk behavior and limited time to provide necessary patient education.

OBJECTIVE

To determine whether pharmacy-based naloxone co-dispensing affected opioid risk behavior. Secondary objectives were to assess if co-dispensing increased naloxone acquisition, increased patient knowledge about naloxone administration, and affected opioid dose and other substance use.

DESIGN

Cluster randomized pragmatic trial of naloxone co-dispensing.

SETTING

Safety-net health system in Denver, Colorado, between 2017 and 2020.

PARTICIPANTS

Seven pharmacies were randomized. Pharmacy patients (N=768) receiving opioids were followed using automated data for 10 months. Pharmacy patients were also invited to complete surveys at baseline, 4 months, and 8 months; 325 survey participants were enrolled from November 15, 2017, to January 8, 2019.

INTERVENTION

Intervention pharmacies implemented workflows to co-dispense naloxone while usual care pharmacies provided usual services.

MAIN MEASURES

Survey instruments assessed opioid risk behavior; hazardous drinking; tobacco, cannabis, and other drug use; and knowledge. Naloxone dispensings and opioid dose were evaluated using pharmacy data among pharmacy patients and survey participants. Intention-to-treat analyses were conducted using generalized linear mixed models accounting for clustering at the pharmacy level.

KEY RESULTS

Opioid risk behavior did not differ by trial group (P=0.52; 8-month vs. baseline adjusted risk ratio [ARR] 1.07; 95% CI 0.78, 1.47). Compared with usual care pharmacies, naloxone dispensings were higher in intervention pharmacies (ARR 3.38; 95% CI 2.21, 5.15) and participant knowledge increased (P=0.02; 8-month vs. baseline adjusted mean difference 1.05; 95% CI 0.06, 2.04). There was no difference in other substance use by the trial group.

CONCLUSION

Co-dispensing naloxone with opioids effectively increased naloxone receipt and knowledge but did not increase self-reported risk behavior.

A qualitative examination of naloxone access in three states: Connecticut, Kentucky, and Wisconsin

BACKGROUND

Prevention of opioid-involved overdose deaths remains a public health priority in the United States. While expanding access to naloxone is a national public health strategy, it is largely implemented at the state and local level, where significant variability in policies, resources, and norms exist. The aims of the current study were to examine the social context of naloxone access in three different states (Connecticut, Kentucky, Wisconsin) from the perspectives of key informants (first responders, harm reduction personnel, and pharmacists), who play some role in dispensing or administering naloxone within their communities.

METHODS

Interviews were conducted with key informants who were in different local areas (urban, suburban, rural) across Connecticut, Kentucky, and Wisconsin. Interview guides explored the key informants' experiences with administering or dispensing naloxone, and their perspectives on opioid overdose prevention efforts in their areas. Data analysis was conducted using multistage inductive coding and comparative methods to identify dominant themes within the data.

RESULTS

Key informants in each of the three states noted progress toward expanding naloxone access, especially among people who use opioids, but also described inequities. The key role of harm reduction programs in distributing naloxone within their communities was also highlighted by participants, as well as barriers to increasing naloxone access through pharmacies. Although there was general consensus regarding the effectiveness of expanding naloxone access to prevent overdose deaths, the results indicate that communities are still grappling with stigma associated with drug use and a harm reduction approach.

CONCLUSION

Findings suggest that public health interventions that target naloxone distribution through harm reduction programs can enhance access within local communities. Strategies that address stigmatizing attitudes toward people who use drugs and harm reduction may also facilitate naloxone expansion efforts, overall, as well as policies that improve the affordability and awareness of naloxone through the pharmacy.

Stigma by Association: To what Extent is the Attitude Toward Naloxone Affected by the Stigma of Opioid Use Disorder?

The United States opioid epidemic is fueled by illicit opioid abuse and prescription opioid misuse and abuse. Consequently, cases of opioid use disorder (OUD, opioid addiction), opioid overdose, and related deaths have increased since the year 2000. Naloxone is an opioid antagonist that rapidly reverses opioid intoxication to prevent death from overdose. It is one of the major risk mitigation strategies recommended in the 2016 Centers for Disease Control and Prevention Guideline for Prescribing Opioids for Chronic Pain. However, despite the exponential increase in dispensing and distribution of naloxone, opioid overdose and related deaths have continued to increase; suggesting that the increased naloxone supply still lags the need. This discordance is attributed at least in part to the negative attitude toward naloxone, which is based on the belief that naloxone is only meant for "addicts" and "abusers" (OUD patients). This negative attitude or so-called naloxone stigma is therefore considered a major barrier for naloxone distribution and consequently, overdose-death prevention efforts. This article presents evidence that challenges common assertions about OUD stigma being the sole and direct driving force behind naloxone stigma, and the purported magnitude of the barrier that naloxone stigma constitutes for naloxone distribution programs among the stakeholders (patients, pharmacists, and prescribers). The case was then made to operationalize and quantify the construct among the stakeholders to determine the extent to which OUD stigma drives naloxone stigma, and the relative impact of naloxone stigma as a barrier for naloxone distribution efforts.

Naloxone therapy for prescription and illicit opioid poisoning cases aged 50 + in the national poison data system, 2015-2020

CONTEXT

Older adults are less likely than younger adults to receive naloxone therapy. Given high rates of prescription opioid use/misuse and increasing illicit opioid use among older adults, factors associated with naloxone administration for older opioid poisoning cases need examination.

METHODS

We analyzed the 83,135 opioid-involved cases aged 50+ from the 2015-2020 National Poison Data System. Single-variable logistic regression was used to examine associations of naloxone administration with demographic factors, exposure site/reason, medical outcomes, management site/level of care, clinical effects, and other interventions. Multivariable logistic regression models were fit to examine associations of naloxone administration with different types of opioids.

RESULTS

Over the six years, the proportion of prescription opioid cases that received naloxone therapy increased steadily from 21.9% to 28.4%. The proportion of illicit opioid cases that received naloxone therapy was 51.9% in 2015 and 59.8% in 2020 with a high of 64.4% in 2019. In 2020, the death rate for illicit opioid cases without naloxone therapy was 31.4% compared to 2.3% for those with the therapy. Cases managed at healthcare facilities (HCF) had higher odds of receiving naloxone therapy. Among prescription opioid cases, naloxone therapy rates among older and female cases and those managed at non-HCF settings were especially low even for major medical outcomes. Cases involving oxycodone, morphine, methadone, prescription fentanyl, hydromorphone, oxymorphone, and other/unknown opioids had higher odds of naloxone administration.

DISCUSSION

Rates of naloxone therapy for older prescription opioid poisoning cases need improvement. While rates were higher among illicit opioid cases, the drop in 2020 and the sharp increase in deaths among illicit opioid cases without naloxone therapy confirm the importance of access to this life-saving intervention.

CONCLUSIONS

Increased naloxone co-prescribing and other means of facilitating access to naloxone are needed to prevent opioid poisoning deaths among older adults who use prescription opioids.

Opioid overdose counseling and prescribing of naloxone in rural community pharmacies: A pilot study

Introduction

Fatal overdoses from opioids increased four-fold from 1999 to 2009, and they are now the leading cause of death among Americans under 50. Legislation has been passed by every state to increase access to naloxone but dispensing by community pharmacies remains low.

Objectives

The objective of this study was to pilot test a proactive opioid overdose counseling intervention and a passive naloxone intervention, and the implementation strategies developed to support their delivery, in rural community pharmacies on relevant implementation outcomes.

Methods

The interventions, implementation strategies, and the overall pilot study approach were developed in a collaborative partnership with a regional supermarket pharmacy chain. They selected 2 rural pharmacies to participate in the pilot study and 2 non-intervention pharmacies to serve as comparison sites. Two interventions were pilot tested in the 2 intervention pharmacies: 1)a proactive opioid overdose counseling intervention and 2) a passive naloxone intervention. An explanatory sequential mixed-methods design was utilized to evaluate adoption, feasibility, acceptability, and appropriateness outcomes after the 3-month observation period.

Results

Between the 2 intervention pharmacies, 130 patients received the opioid overdose counseling intervention. 44 (33.8%) were prescribed and dispensed naloxone. Zero naloxone prescriptions were written or dispensed at the comparison pharmacies. Interviews with pharmacy staff found the interventions to be feasible, acceptable, and appropriate in their settings.

Conclusion

This small scale pilot study in partnership with a regional supermarket pharmacy chain had positive results with a third of patients who received the opioid overdose counseling intervention being dispensed naloxone. However, the majority of patients did not receive naloxone indicating additional revisions to the intervention components and/or implementation strategies are needed to improve the overall impact of the interventions.

The Impact of a PDMP-EHR Data Integration Combined With Clinical Decision Support on Opioid and Benzodiazepine Prescribing Across Clinicians in a Metropolitan Area

INTRODUCTION

Despite inconclusive evidence that prescription drug monitoring programs (PDMP) reduce opioid-related mortality, guidelines recommend PDMP review with opioid prescribing. Some reported barriers to use include time-consuming processes to obtain data and workflow disruptions.

METHODS

We provided access to a PMDP-electronic health record (EHR) integrated program to 123 clinicians in one healthcare system. Remaining clinicians within the healthcare system and metropolitan area did not receive PDMP-EHR integration program access. We identified changes in opioid prescribing by linking prescription data available in the state PMDP database to individual clinicians. The primary outcome was change in receipt of high dose opioid prescriptions (>90 mg morphine equivalents) by Colorado residents before and after program integration. Secondary outcomes included changes in long-acting opioid receipt and overlapping opioid and benzodiazepine prescription days. Next, we surveyed clinicians to assess their perspectives on PDMP data acquisition before and after PDMP-EHR integration program access.

RESULTS

High-dose opioid receipt decreased significantly across all 3 clinician groups [PDMP-EHR integration program access (27.6%, to 6.9%, P < 0.001); no program access in the same healthcare system (4.8% to 2.9%, P < 0.001), and no program access across the metropolitan area (13.5% to 6.1%, P < 0.001)]. Clinicians reported improved access to PDMP data using the PDMP-EHR integrated program compared to the state PDMP website (98.6%).

CONCLUSIONS

Further study of PDMP-EHR integration programs on patient and clinician outcomes may illuminate the role of this technology in public health and in clinical practice.

The role of managed care pharmacy in coprescribing naloxone for patients with specific risk: recommendations from the AMCP Addiction Advisory Group

Prescription opioid misuse remains a significant cause of morbidity and mortality associated with drug overdose. Researchers, government agencies, public health interests, and professional organizations support the benefits of naloxone coprescribing for patients on chronic opioid therapy to prevent deaths from opioid overdose. However, gaps remain in the provision of naloxone to patients at risk. Currently, less than 1% of patients who should be prescribed naloxone with their opioid medications obtain a prescription for naloxone, illustrating an opportunity for health care providers to conduct thorough risk assessments for patients taking opioids and coprescribing naloxone to those at risk. There are documented barriers to the provision of naloxone for primary care providers, pharmacists, and patients. Managed care organizations have also created barriers. To better understand and evaluate trends in treatment, coverage, policies, and needs associated with providing health services to patients with substance use disorders, the Academy of Managed Care Pharmacy (AMCP) Addiction Advisory Group conducted a survey in 2019. Eighty percent of the managed behavioral health organizations and 47% of AMCP payer members who responded to the survey encouraged naloxone coprescribing in patients at high risk of overdose; however, no organizations require coprescribing. Health plans, managed care organizations, prescribers, pharmacists, patients, and others have important roles in decreasing the morbidity and mortality associated with opioid overdose. In particular, managed care organizations can take specific and meaningful actions to implement payment policies that improve naloxone coprescribing for patients at risk. In this article, opportunities have been outlined for managed care leadership that actively support public health policies for naloxone coprescribing, and 7 recommendations are presented. DISCLOSURES: The AMCP Addiction Advisory Group and the development of this article were supported by Alkermes and Precision Toxicology. Sponsors participated in the advisory group, which provided guidance in the development of the manuscript. Dharbhamalla is employed by AMCP. Skelton is a paid consultant working with AMCP.

Communication between patients and health care professionals about opioid medications

Prescription opioids contribute to 40% of opioid overdose deaths in the United States. Healthcare professionals (HCPs) play an important role in mitigating the prescription opioid epidemic by appropriate opioid prescribing and patient education. Yet, little empirical literature addresses pharmacist (and other HCP) communication with patients related to risks of opioid use associated with dependence, misuse, and overdose. Nor is there much research on the barriers and facilitators which affect whether and how much opioid-related information is discussed. This commentary, based on an extensive literature search, seeks to inform future communication, education, and research agendas by describing (1) topics commonly discussed or excluded from opioid medication counseling, (2) patient and HCP perceptions regarding opioid medication communication, and (3) barriers and facilitators to opioid risk communication. Based on this literature, recommendations are provided for opioid counseling practices, pharmacist education, and research agendas.

Impact of policy changes on the provision of naloxone by pharmacies in Ontario, Canada: a population-based time-series analysis

BACKGROUND AND AIMS

In June 2016, the Ontario, Canada government implemented the Ontario Naloxone Program for Pharmacies (ONPP), authorizing pharmacists to provide injectable naloxone kits at no charge to all Ontario residents. In March 2018, the program was amended to include intranasal naloxone and remove the requirement to present a government health card to the dispensing pharmacist. We examined whether these changes increased naloxone dispensing through the ONPP.

DESIGN

Population-based time-series analysis using interventional autoregressive integrated moving average models.

SETTING

Ontario, Canada.

PARTICIPANTS

All Ontario residents between 1 July 2016 and 31 March 2020.

MEASUREMENTS

Monthly rates of pharmacy naloxone dispensing.

FINDINGS

Overall, 199 484 individuals were dispensed a naloxone kit during the study period. In the main analysis, the rate of pharmacy naloxone dispensing increased by 65.1% following program changes (55.6-91.8 kits per 100 000 population between February 2018 and May 2018; P = 0.01). In subgroup analyses, naloxone dispensing increased among individuals receiving opioid agonist therapy (OAT) (3374.9-7264.2 kits per 100 000 OAT recipients; P = 0.04) among individuals receiving other prescription opioids (192.8-381.8 kits per 100 000 population prescribed opioids; P < 0.01), among individuals with past opioid exposure (134.7-205.6 kits per 100 000 population with past opioid exposure; P < 0.01) and in urban centers (56.2-91.4 kits per 100 000 population; P < 0.01). We did not observe a clear impact on pharmacy-dispensed naloxone to individuals with no or unknown opioid exposure (34.4-39.3 kits per 100 000 population with no/unknown opioid exposure; P = 0.42) and in rural regions (50.4-97.2 kits per 100 000 population; P = 0.09).

CONCLUSIONS

Changes to the Ontario Naloxone Program for Pharmacies to add intranasal naloxone and remove the requirement to present a government health card appeared to increase pharmacy-based naloxone dispensing uptake in Ontario, Canada, particularly among individuals at high risk of inadvertent opioid overdose.

Modifying and Evaluating the Opioid Overdose Knowledge Scale for Prescription Opioids: A Pilot Study of the Rx-OOKS

OBJECTIVE

To develop a validated instrument that measures knowledge about prescription opioid overdose.

METHODS

Within an integrated health care system, we adapted, piloted, and tested the reliability and predictive validity of a modified Opioid Overdose Knowledge Scale (OOKS) instrument specific to prescription opioids (Rx-OOKS) with a patient population prescribed long-term opioid therapy and potentially at risk of opioid overdose. We used an interdisciplinary team approach and patient interviews to adapt the instrument. We then piloted the survey on a patient sample and assessed it using Cronbach's alpha and logistic regression.

RESULTS

Rx-OOKS (N = 56) resulted in a three-construct, 25-item instrument. Internal consistency was acceptable for the following constructs: "signs of an overdose" (10 items) at α = 0.851, "action to take with opioid overdose" (seven items) at α = 0.692, and "naloxone use knowledge" (eight items) at α = 0.729. One construct, "risks of an overdose" (three items), had an α of 0.365 and was subsequently eliminated from analysis due to poor performance. We conducted logistic regression to determine if any of the constructs was strongly associated with future naloxone receipt. Higher scores on "actions to take in an overdose" had nine times the odds of receiving naloxone (odds ratio [OR] = 9.00, 95% confidence interval [CI] = 1.42-57.12); higher "naloxone use knowledge" scores were 15.8 times more likely to receive naloxone than those with lower scores (OR = 15.83, 95% CI = 1.68-149.17).

CONCLUSIONS

The Rx-OOKS survey instrument can reliably measure knowledge about prescription opioid overdose recognition and naloxone use. Further, knowledge about actions to take during an opioid overdose and naloxone use were associated with future receipt of naloxone.

Patient perspectives of barriers to naloxone obtainment and use in a primary care, underserved setting: A qualitative study

Background: Gaps in naloxone obtainment and use are not well studied, particularly among minoritized groups. Objective: To describe patient perspectives that serve as barriers to naloxone obtainment and the number of patients who obtained naloxone in a primarily African American population in a primary care, underserved setting. Methods: This qualitative study conducted semi-structured interviews and included 36 adults who were prescribed naloxone at a federally qualified health center using convenience sampling. Participants answered survey questions describing naloxone acceptability, perceived risk for overdose, and barriers to naloxone use. Results: Sixty-nine percent of the patients were Black or African American. The majority of patients attempted to fill their naloxone at a local pharmacy (69%) and reported no difficulties (88%). Five major themes revealed: overall positive views of naloxone because it saves lives; existing knowledge gaps related to indications for naloxone prescription; stigma surrounding receiving a naloxone prescription; inadequacies of the patient education provided; and the role providers play in naloxone receptivity Conclusions: Among a majority African American population, many perceived naloxone to be lifesaving. However, stigmatizing perceptions and inability to recall patient education contribute to a perception of low overdose risk. Further research describing the impact of the opioid epidemic on underrepresented groups is necessary.

New and Emerging Opioid Overdose Risk Factors

Purpose of Review

The purpose of this review is to provide a review of the current literature surrounding opioid overdose risk factors, focusing on relatively new factors in the opioid crisis.

Recent Findings

Both a market supply driving force and a subpopulation of people who use opioids actively seeking out fentanyl are contributing to its recent proliferation in the opioid market. Harm reduction techniques such as fentanyl testing strips, naloxone education and distribution, drug sampling behaviors, and supervised injection facilities are all seeing expanded use with increasing amounts of research being published regarding their effectiveness. Availability and use of interventions such as medication for opioid use disorder and peer recovery coaching programs are also on the rise to prevent opioid overdose.

Summary

The opioid epidemic is an evolving crisis, necessitating continuing research to identify novel overdose risk factors and the development of new interventions targeting at-risk populations.

Naloxone receipt and overdose prevention care among people with HIV on chronic opioid therapy

This cross-sectional study describes naloxone rescue kit receipt among people with HIV (PWH) on chronic opioid therapy (COT) and HIV clinician opioid overdose prevention care in two clinics between 2015 and 2017. Naloxone rescue kit receipt was uncommon. History of overdose was associated with receiving naloxone but having a clinician who reported providing overdose prevention care was not. This study suggests that clinicians prescribing COT to PWH should improve overdose prevention care, including naloxone co-prescribing.

Challenges and Facilitators of Implementing a Physician-approved Naloxone Protocol: A Mixed-methods Study

OBJECTIVES

In 2015, the State of Ohio passed legislation to allow pharmacists to dispense naloxone under a physician-approved protocol. The legislation allows all individuals authorized under a physician-approved protocol to personally furnish naloxone without requiring clients to be seen by a licensed prescriber, thus expanding the capacity of Ohio's community distribution programs. We aimed to evaluate the implementation of legislation allowing for a physician-approved protocol in pharmacies and other naloxone distribution sites in Ohio, and to compare barriers and facilitators of implementing the law changes among sites that implemented a physician-approved protocol versus sites that did not.

METHODS

The study used a convergent parallel mixed-method design. Random samples from all pharmacies registered with the State of Ohio Board of Pharmacy and community naloxone distribution sites were selected. Quantitative data were collected via survey (n = 168) and qualitative data were collected via semi-structured interviews (n = 17).

RESULTS

Most survey respondents agreed that the policy has expanded access to naloxone at their site for individuals who want or need the medication. Both pharmacies and other naloxone distribution sites identified that leadership and organizational support facilitated protocol implementation and cost, stigma, and lack of naloxone demand challenged protocol implementation.

CONCLUSIONS

The study identified barriers and facilitators to the implementation of a physician-approved protocol within Ohio. The majority of respondents stated they could implement a protocol. However, barriers of cost, lack of public awareness of naloxone availability, and stigma remain for pharmacies and other naloxone distribution sites.

Stakeholders' Perceptions of Factors Influencing the Use of Take-Home-Naloxone

Background and Aims: Opioid associated death and overdose is a growing burden in societies all over the world. In recent years, legislative changes have increased access to naloxone in the take-home setting for use by patients with a substance use disorder and bystanders, to prevent opioid overdose deaths. However, few studies have explored the factors influencing the uptake by its multiple stakeholders. The aim of this scoping review was to explore the factors influencing the use of take-home naloxone from the perspectives of different stakeholders. Methods: A scoping review methodology was adopted with a systematic search of databases EMBASE, MEDLINE and PubMed. A variation of the search words “naloxone”, “opioid” and “overdose” were used in each database. The articles were screened according to the predetermined inclusion/exclusion criteria and categorized based on their key perspective or target population. Results: The initial database search yielded a total of 1483 articles. After a series of screening processes, 51 articles were included for analysis. Two key stakeholder perspectives emerged: patients and bystanders (n = 36), and healthcare professionals (n = 15). Within the patient and bystander group, a strong consensus arose that there were positive outcomes from increased access to take-home naloxone and relevant training programs. Despite these positive outcomes, some healthcare professionals were concerned that take-home naloxone would encourage high-risk opioid use. Conclusion: Take-home naloxone is slowly being introduced into community practice, with a sense of enthusiasm from patients and bystanders. There are still a number of barriers that need to be addressed from healthcare professionals’ perspective. Future research should be aimed at emergency care professionals outside of the US, who are most experienced with naloxone and its potential impact on the community.

Geographic variation in the provision of naloxone by pharmacies in Ontario, Canada: A population-based small area variation analysis

BACKGROUND

Regional variation in pharmacy-dispensed naloxone rates could create access disparities that undermine the effectiveness of this approach. We explored individual and public health unit (PHU)-level determinants of regional variation in naloxone distribution through the Ontario Naloxone Program for Pharmacies.

METHODS

We conducted a population-based study between April 1, 2017 and March 31, 2018. We calculated age- and sex-standardized pharmacy-dispensed naloxone rates for the 35 Ontario PHUs, and identified determinants of these rates using generalized estimating equations negative binomial regression.

RESULTS

The age- and sex-standardized pharmacy-dispensed naloxone rate in Ontario was 5.5 (range 1.8-11.6) kits per 1000 population. Variables associated with higher naloxone dispensing rates included opioid use disorder history [rate ratio (RR) 2.27; 95% confidence interval (CI) 1.75-2.96], opioid agonist therapy (RR 11.17; 95% CI 7.15-17.44), and PHU opioid overdose rate (RR 1.09 per 10 deaths; 95% CI 1.06-1.13). Pharmacy-dispensed naloxone rates were lower in rural areas (RR 0.83; 95% CI 0.73-0.94) and among individuals dispensed one (RR 0.72; 95% CI 0.65-0.79), two to five (RR 0.67; 95% CI 0.54-0.84) or 6-10 (RR 0.92; 95% CI 0.74-1.14) opioids in the prior year relative to those receiving no opioids.

CONCLUSION

Pharmacy-dispensed naloxone programs are important components of a public health response to the opioid overdose crisis. We found considerable variation in pharmacy-dispensed naloxone rates that could limit program effectiveness, particularly in rural settings with limited access to health and harm reduction services..

Patient acceptance of naloxone resulting from targeted intervention from community pharmacists to prevent opioid misuse and accidental overdose

Background: Community pharmacists are in a unique position to prevent opioid-related deaths through the provision of naloxone. However, for those identified as candidates for take-home naloxone, the acceptance rate remains low. Value would be gained from knowing what patient demographics and pharmacist actions are associated with increased patient acceptance of naloxone. Methods: Through a state-wide program, community pharmacists screened all patients receiving an opioid prescription for risk of opioid misuse and/or accidental overdose. Pharmacists prescribed and/or dispensed take-home naloxone to patients at elevated risk. Naloxone acceptance rates were stratified based on risk factors for misuse and overdose to determine which patients are most likely to accept naloxone. Patient acceptance of naloxone and risks were captured electronically. Results: Pharmacist-initiated naloxone recommendations based on risk screening resulted in a 5.81% take-home naloxone acceptance rate. Individuals that were taking multiple opioid medications were most likely to accept the naloxone (20.45%). Concurrent disease states or medications (COPD, concurrent anxiety/depression medication, concurrent sleep aid) were associated with a statistically significant increase in the rate of naloxone acceptance. Acceptance of take-home naloxone increased as a patient risk for opioid misuse and/or accidental overdose increased. Conclusion: Patient acceptance of naloxone at the community pharmacy level was notably higher compared to national naloxone dispensing rates when pharmacists implemented a patient screening and systematic risk-based approach to identify candidates in need of take-home naloxone.

Increasing Naloxone Knowledge and Use Through Direct-to-Patient Education

Background: In the United States, opioid overdoses account for 130 deaths daily. Barriers to obtaining naloxone, the drug-of-choice for opioid overdose reversal, include limited education, access, and perceptions of provider judgement. Objectives: This study aimed to assess the efficacy of mailed education about naloxone, with or without a live teaching seminar, to patients at risk for opioid overdose. Methods: This observational study was conducted in a federally qualified health system. A phone presurvey was administered to patients on long-term opioid therapy or with a diagnosis of opioid use disorder to assess opioid overdose-related knowledge. Subjects were mailed a handout about naloxone and an invitation to receive naloxone at no cost at a seminar. Three-month phone postsurveys were conducted. The primary outcome was change in mean knowledge score from presurvey to postsurvey. Secondary outcomes included scores on individual survey items, naloxone prescriptions provided, and overdose reversals reported. Results: Ninety-four patients received mailed education. Sixty-two subjects took presurveys and 23 took 3-month follow-up surveys. Five subjects attended the live seminar. The mean cumulative knowledge score improved by 8.7% from the presurvey to the postsurvey. During the study period, one new naloxone prescription was written and one overdose reversal was reported. Conclusion: Direct-to-patient mailed education slightly improved knowledge regarding naloxone and opioid overdose response, and it may have led to one successful overdose reversal. Mailing education to a larger population of patients at risk for opioid overdose may be necessary to observe a substantial clinical impact.

Revisiting pharmacy-based naloxone with pharmacists and naloxone consumers in 2 states: 2017 perspectives and evolving approaches

OBJECTIVES

Pharmacies provide accessible sources of naloxone to caregivers, patients taking opioids, and individuals using drugs. While laws permit expanded pharmacy naloxone access, prior work identified barriers like concerns about stigma of addiction and time constraints that inhibit scale-up. We sought to examine similarities and differences in experiences obtaining naloxone at the pharmacy over a 1-year period in 2 states, and to explore reactions from people with opioid use disorder, patients taking opioids for chronic pain, caregivers of opioid users, and pharmacists to communication tools and patient outreach materials designed to improve naloxone uptake.

DESIGN

Eight focus groups (FGs) held December 2016 to April 2017 in Massachusetts and Rhode Island.

SETTING AND PARTICIPANTS

Participants were recruited from pharmacies, health clinics, and community organizations; pharmacists were recruited from professional organizations and pharmacy colleges.

OUTCOME MEASURES

The FGs were led by trained qualitative researchers using a topic guide and prototypes designed for input. Five analysts applied a coding scheme to transcripts. Thematic analysis involved synthesis of coded data and connections between themes, with comparisons across groups and to first-year findings.

RESULTS

A total of 56 individuals participated: patients taking opioids for chronic pain (n = 13), people with opioid use disorders (n = 15), caregivers (n = 13), and pharmacists (n = 16). Fear of future consequences and stigma in the pharmacy was a prominent theme from the previous year. Four new themes emerged: experience providing pharmacy naloxone, clinician-pharmacist-partnered approaches, naloxone coprescription, and fentanyl as motivator for pharmacy naloxone. Prototypes for prompting consumers about naloxone availability, materials facilitating naloxone conversations, and posters designed to address stigma were well received.

CONCLUSIONS

Experiences dispensing naloxone are quickly evolving, and a greater diversity of patients are obtaining pharmacy naloxone. Persistent stigma-related concerns underscore the need for tools to help pharmacists offer naloxone, facilitate patient requests, and provide reassurance when getting naloxone.

Opportunities to boost naloxone awareness among people who misuse opioid analgesics who have not used illegal opioids

BACKGROUND

Increasing naloxone awareness and carrying among individuals who misuse opioid analgesic medications (OAs) could reduce opioid overdose mortality. Methods: Self-report surveys were completed by 322 adults receiving residential addiction treatment who misused OAs in the past year. Descriptive analyses and prevalence ratios (using Poisson generalized estimating equations) examined whether illegal opioid (e.g., heroin) initiation was associated with naloxone awareness. Results: Among this sample of participants who misused OAs, naloxone awareness was lowest among those who never used illegal opioids (26%) and highest among those who transitioned from OAs to illegal opioid use over time (83%). Naloxone awareness remained higher among participants who had used illegal opioids after adjustment for sociodemographic and substance use characteristics. Those who used OAs before initiating illegal opioids were 2.3-fold (95% CI: 1.5-3.3) more likely to have naloxone awareness than those who had only misused OAs after adjustment. Half of participants who had only used OAs had experienced an overdose, 75% had witnessed an overdose, and 61% were prescribed OAs to treat pain in the past 6 months. Conclusions: Implementing overdose education and naloxone distribution programs during addiction treatment could bolster naloxone awareness among people who misuse OAs but who have not used illegal opioids.

Cost-Effectiveness of Intranasal Naloxone Distribution to High-Risk Prescription Opioid Users

OBJECTIVES

To determine the cost-effectiveness of pharmacy-based intranasal naloxone distribution to high-risk prescription opioid (RxO) users.

METHODS

We developed a Markov model with an attached tree for pharmacy-based naloxone distribution to high-risk RxO users using 2 approaches: one-time and biannual follow-up distribution. The Markov structure had 6 health states: high-risk RxO use, low-risk RxO use, no RxO use, illicit opioid use, no illicit opioid use, and death. The tree modeled the probability of an overdose happening, the overdose being witnessed, naloxone being available, and the overdose resulting in death. High-risk RxO users were defined as individuals with prescription opioid doses greater than or equal to 90 morphine milligram equivalents (MME) per day. We used a monthly cycle length, lifetime horizon, and US healthcare perspective. Costs (2018) and quality-adjusted life-years (QALYs) were discounted 3% annually. Microsimulation was performed with 100 000 individual trials. Deterministic and probabilistic sensitivity analyses were conducted.

RESULTS

One-time distribution of naloxone prevented 14 additional overdose deaths per 100 000 persons, with an incremental cost-effectiveness ratio (ICER) of $56 699 per QALY. Biannual follow-up distribution led to 107 additional lives being saved with an ICER of $84 799 per QALY compared with one-time distribution. Probabilistic sensitivity analyses showed that a biannual follow-up approach would be cost-effective 50% of the time at a willingness-to-pay (WTP) threshold of $100 000 per QALY. Naloxone effectiveness and proportion of overdoses witnessed were the 2 most influential parameters for biannual distribution.

CONCLUSION

Both one-time and biannual follow-up naloxone distribution in community pharmacies would modestly reduce opioid overdose deaths and be cost-effective at a WTP of $100 000 per QALY.

The role of substance use disorders in experiencing a repeat opioid overdose, and substance use treatment patterns among patients with a non-fatal opioid overdose

BACKGROUND

A non-fatal opioid overdose (NFOO) increases the risk of another overdose and identifies high-risk patients. We estimated the risk of repeat opioid overdose for patients with and without substance use disorder (SUD) diagnoses and the change in substance use treatment utilization rates associated with the first NFOO.

METHODS

We selected patients (>18 years of age) from Kaiser Permanente Northern California with a NFOO between 2009-2016 (n = 3,992). Cox proportional hazards models estimated the 1-year risk of opioid overdose associated with SUD diagnoses (opioid, alcohol, cannabis, amphetamine, sedative, and cocaine), controlling for patient characteristics. Among patients with an index NFOO, we calculated monthly utilization rates for outpatient substance use services and buprenorphine before and after the index overdose. Interrupted time series models estimated the change in level and trend in utilization rates associated with the index overdose.

RESULTS

Approximately 7.2 % of patients had a repeat opioid overdose during the year after the index NFOO. The only SUD diagnosis significantly associated with greater risk of repeat overdose was opioid use disorder (OUD) (aHR: 1.51; 95 % CI: 1.13-2.01). Before the index overdose, 4.16 % of patients received outpatient substance use services and 1.32 % received buprenorphine. The index overdose was associated with a 5.94 % (standard error: 0.77 %) absolute increase in outpatient substance use services and a 1.29 % (standard error: 0.15 %) increase in buprenorphine.

CONCLUSION

Patients with a NFOO and OUD are vulnerable to another overdose. Low initiation rates for substance use treatment after a NFOO indicate a need to address patient, provider, and system barriers.

Experiences of people taking opioid medication for chronic non-malignant pain: a qualitative evidence synthesis using meta-ethnography

OBJECTIVE

To review qualitative studies on the experience of taking opioid medication for chronic non-malignant pain (CNMP) or coming off them.

DESIGN

This is a qualitative evidence synthesis using a seven-step approach from the methods of meta-ethnography.

DATA SOURCES AND ELIGIBILITY CRITERIA

We searched selected databases-Medline, Embase, AMED, Cumulative Index to Nursing and Allied Health Literature, PsycINFO, Web of Science and Scopus (Science Citation Index and Social Science Citation Index)-for qualitative studies which provide patients' views of taking opioid medication for CNMP or of coming off them (June 2017, updated September 2018).

DATA EXTRACTION AND SYNTHESIS

Papers were quality appraised using the Critical Appraisal Skills Programme tool, and the GRADE-CERQual (Grading of Recommendations Assessment, Development and Evaluation working group - Confidence in Evidence from Reviews of Qualitative research) guidelines were applied. We identified concepts and iteratively abstracted these concepts into a line of argument.

RESULTS

We screened 2994 unique citations and checked 153 full texts, and 31 met our review criteria. We identified five themes: (1) reluctant users with little choice; (2) understanding opioids: the good and the bad; (3) a therapeutic alliance: not always on the same page; (4) stigma: feeling scared and secretive but needing support; and (5) the challenge of tapering or withdrawal. A new overarching theme of 'constantly balancing' emerged from the data.

CONCLUSIONS

People taking opioids were constantly balancing tensions, not always wanting to take opioids, and weighing the pros and cons of opioids but feeling they had no choice because of the pain. They frequently felt stigmatised, were not always 'on the same page' as their healthcare professional and felt changes in opioid use were often challenging.

Association Between a State Law Allowing Pharmacists to Dispense Naloxone Without a Prescription and Naloxone Dispensing Rates

IMPORTANCE

Between 2015 and 2017, Ohio had the second highest number of opioid-related deaths. In July 2015, the Ohio General Assembly approved a law allowing pharmacists to dispense naloxone without a prescription in accordance with a physician-approved protocol. This change in the law allowed pharmacists to have more opportunity to participate in the management of patients who were addicted to opioids.

OBJECTIVE

To determine the association between the implementation of an Ohio law allowing pharmacists to dispense naloxone without a prescription in accordance with a physician-approved protocol and naloxone dispensing rates.

DESIGN, SETTING, AND PARTICIPANTS

A segmented regression analysis of an interrupted time series was performed for 30 consecutive months to evaluate the change in the naloxone dispensing rate before and after the implementation of the state law. Ohio Medicaid naloxone claims and Kroger Pharmacy naloxone claims for all 88 counties in Ohio were examined. Any patient 18 years or older with at least 1 naloxone order dispensed through Ohio Medicaid or by a Kroger Pharmacy in Ohio during the study period of July 16, 2014, to January 15, 2017, was included in the study. Data were analyzed from April 23, 2018, to July 7, 2019.

EXPOSURES

The primary independent variable was implementation of an Ohio law allowing pharmacists to dispense naloxone without a prescription in accordance with a physician-approved protocol, which took effect in July 2015.

MAIN OUTCOMES AND MEASURES

The primary outcome measure was the naloxone dispensing rate per month per county.

RESULTS

In the Ohio Medicaid population, the number of naloxone orders dispensed after the policy was implemented increased by 2328%, from 191 in the prepolicy period to 4637 in the postpolicy period. The rate of naloxone orders dispensed per month per county after the policy was implemented increased by 4% in the Ohio Medicaid population and 3% in the Kroger Pharmacy population compared with the prepolicy period. The rate of naloxone orders dispensed after the policy was implemented increased by 18% per month in low-employment counties compared with high-employment counties in the Ohio Medicaid population.

CONCLUSIONS AND RELEVANCE

The implementation of a state law allowing pharmacists to dispense naloxone without a prescription in accordance with a physician-approved protocol was associated with an increase in the number of naloxone orders dispensed in the Ohio Medicaid and Kroger Pharmacy populations. Moreover, a significant increase was observed in the naloxone dispensing rate among the Ohio Medicaid population in counties with low employment and high poverty.

"It's Took Over This Region": Patient Perspectives of Prescription Drug Abuse in Appalachia

Background: Prescription drug abuse is a public health problem in the United States and the region of Appalachia, specifically. Primary care and addiction medicine-as possible points of access for prescription drugs with abuse potential and points of intervention for prescription drug abuse-are among the medical fields at its forefront. Little is known, however, about perceptions of prescription drug abuse across the two patient populations. Objectives: The objective of this qualitative analysis was to explore perceptions of the scale and context of prescription drug abuse among primary care and addiction medicine patients in Appalachia. Methods: As part of a mixed methods study, semi-structured interviews were conducted with 20 patients from primary care and addiction medicine in Central and South Central Appalachia from 2014 to 2015. The interviews were audio-recorded and transcribed verbatim. Thematic analysis was used to identify themes. Results: Three themes were identified: (1) pervasiveness of prescription drug abuse, describing perceptions of its high prevalence and negative consequences; (2) routes and routine practices for prescription drug acquisition and distribution, describing perceptions of routes of access to prescription drugs and behaviors exhibited to acquire and distribute prescription drugs; and (3) rationales for prescription drug acquisition and distribution, describing perceptions of the two underlying reasons for these processes-tolerance/addiction and revenue source. Conclusions/Importance: Perceptions of prescription drug abuse among primary care and addiction medicine patients in Appalachia are multifaceted, especially regarding prescription drug acquisition and distribution. Clinical practice implications for mitigating prescription drug abuse are discussed.

Opposition to Nonprescription Naloxone Access: Measurement and Psychosocial Predictors

Background: Access of naloxone has been increased in recent years, yet opposition to unrestricted availability persists. Objectives: To validate a measure of opposition to the policy of nonprescription naloxone and foster a better understanding of the characteristics of individuals who oppose such a policy. Methods: Respondents from a crowdsource platform (N = 621) responded to an instrument developed to assess opposition to nonprescription naloxone. Construct validity was assessed by examining the relationship of the opposition scale with measures of social distance, belief in a just world, right wing authoritarianism, social dominance orientation (SDO), perceptions of the degree of threat to the nation presented by opioid users, past exposure to opioid misuse, and conservative political ideology. Results: A 9-item measure of opposition emerged (α=.96). Opposition to nonprescription naloxone was generally associated with construct validation variables as expected. In a regression analysis that adjusted for demographic characteristics, opposition was most strongly related to authoritarianism, the perception that opioid users present a threat to our nation, the belief that we live in a just world, social dominance orientation, greater perceived social distance between self and opioid users, and past experiences with users. Opposition scores differentiated those who supported versus opposed specific policies regarding naloxone access and were particularly high among Republicans. Most respondents did not oppose policies on nonprescription naloxone access. Conclusions/Importance: The instrument developed provides a reliable and valid tool that enables future investigations into understanding and overcoming the psychological, social, and political foundations of opposition to expanded naloxone access.

Novel Opioid Safety Clinic Initiative to Deliver Guideline-Concordant Chronic Opioid Therapy in Primary Care

Objective

To develop and evaluate a novel Opioid Safety Clinic (OSC) initiative to enhance adherence to guidelines on the assessment and monitoring of patients prescribed chronic opioid therapy (COT).

Patients and Methods

The OSC was developed at an urban Federally Qualified Health Center to provide guideline-concordant care for COT, standardize workflows, and efficiently use clinic staff. We evaluated the OSC using a matched cohort study. Five hundred thirty-nine patients participated in the clinic between July 1, 2014, and March 31, 2016. Of these, 472 clinic participants were matched to 472 nonparticipants by sex and age on the date of the OSC visit. The OSC was evaluated by its completion rates of standardized pain assessments, urine toxicology, and naloxone dispensings. We conducted logistic regression comparing OSC participants to OSC nonparticipants.

Results

A total of 539 patients attended an OSC visit, representing approximately 53% of patients in the chronic opioid registry. The OSC participants were more likely than nonparticipants to have completed a pain assessment (adjusted odds ratio [aOR], 169.8; 95% CI, 98.3-293.5), completed a urine toxicology (aOR, 46.1; 95% CI, 30.4-69.9), or had naloxone dispensed (aOR, 2.8; 95% CI, 1.9-4.3) over 12 months of follow-up.

Conclusion

The OSC model improved adherence to guideline-concordant COT in primary care. Future research is needed to assess the impact of these interventions on pain, quality of life, and adverse events from opioid analgesics.

Prediction Model for Two-Year Risk of Opioid Overdose Among Patients Prescribed Chronic Opioid Therapy

BACKGROUND

Naloxone is a life-saving opioid antagonist. Chronic pain guidelines recommend that physicians co-prescribe naloxone to patients at high risk for opioid overdose. However, clinical tools to efficiently identify patients who could benefit from naloxone are lacking.

OBJECTIVE

To develop and validate an overdose predictive model which could be used in primary care settings to assess the need for naloxone.

DESIGN

Retrospective cohort.

SETTING

Derivation site was an integrated health system in Colorado; validation site was a safety-net health system in Colorado.

PARTICIPANTS

We developed a predictive model in a cohort of 42,828 patients taking chronic opioid therapy and externally validated the model in 10,708 patients.

MAIN MEASURES

Potential predictors and outcomes (nonfatal pharmaceutical and heroin overdoses) were extracted from electronic health records. Fatal overdose outcomes were identified from state vital records. To match the approximate shelf-life of naloxone, we used Cox proportional hazards regression to model the 2-year risk of overdose. Calibration and discrimination were assessed.

KEY RESULTS

A five-variable predictive model showed good calibration and discrimination (bootstrap-corrected c-statistic = 0.73, 95% confidence interval [CI] 0.69-0.78) in the derivation site, with sensitivity of 66.1% and specificity of 66.6%. In the validation site, the model showed good discrimination (c-statistic = 0.75, 95% CI 0.70-0.80) and less than ideal calibration, with sensitivity and specificity of 82.2% and 49.5%, respectively.

CONCLUSIONS

Among patients on chronic opioid therapy, the predictive model identified 66-82% of all subsequent opioid overdoses. This model is an efficient screening tool to identify patients who could benefit from naloxone to prevent overdose deaths. Population differences across the two sites limited calibration in the validation site.

Acceptability and feasibility of naloxone prescribing in primary care settings: A systematic review

Naloxone access through established healthcare settings is critical to responding to the opioid crisis. We conducted a systematic review to assess the acceptability and feasibility of prescribing naloxone to patients in primary care. We queried PubMed, EmBase and CINAHL for US-based, peer-reviewed, full-length, original articles relating to acceptability or feasibility of prescribing naloxone in primary care. Searches yielded 270 unduplicated articles; one analyst reviewed all titles and abstracts. Two analysts independently reviewed eligible articles for study design, study outcome, and acceptability and/or feasibility. Analyses were compared and a third reviewer consulted if discrepancies emerged. Seventeen articles were included. Providers' willingness to prescribe naloxone appeared to increase over time. Most studies provided prescribers in-person naloxone trainings, including how to write a prescription and indications for prescribing. Most studies implemented universal prescribing, whereby anyone prescribed long-term opioids or otherwise at risk for overdose was eligible for naloxone. Patient education was largely provided by prescribers and most studies provided take-home educational materials. Providers reported concerns around naloxone prescribing including lack of knowledge around prescribing and educating patients. Providers also reported benefits such as improving difficult conversations around opioids and resetting the culture around opioids and overdose. Current literature supports the acceptability and feasibility of naloxone prescribing in primary care. Provision of naloxone through primary care may help normalize such medication safety interventions, support larger opioid stewardship efforts, and expand access to patients not served by a community distribution program.

Preventing Opioid Overdose in the Clinic and Hospital: Analgesia and Opioid Antagonists

Drawing from existing opioid prescribing guidelines, this article describes how medical providers can reduce the risk of overdose. Through primary prevention, providers can prevent initial exposure and associated risks by educating patients, using risk stratification, minimizing opioid dose and duration, and avoiding coprescribing with sedatives. Secondary prevention efforts include monitoring patients with urine toxicology and prescription monitoring programs, and screening for opioid use disorders. Tertiary prevention includes treating opioid use disorders and providing naloxone to prevent overdose death. Specific preventive strategies may be required for those with psychiatric disorders or substance use disorders, adolescents, the elderly, and pregnant women.

Prescribing naloxone for opioid overdose intervention

To provide an update on prescription of naloxone as a harm-reduction strategy, PubMed was searched to identify publications relevant to naloxone prescribing for reversal of opioid overdose. Opportunities now exist to expand naloxone use, although evidence suggests these are often missed or underexploited. The US FDA has approved an intranasal naloxone spray and an autoinjector naloxone formulation for community use. Effective use of naloxone in community settings requires screening to identify patients at risk of opioid overdose, discussing naloxone use with patients and their relatives, and providing appropriate training. The tools exist to expand the use of naloxone more widely into the community, thereby creating an opportunity to reduce opioid overdose fatalities.
