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

Development of pharmacy-based best practices to support safer use and management of prescription opioids based on an e-Delphi methodology

BACKGROUND

Opioid utilization and related harm have increased in recent decades, notably in Australia, the United States, Canada, and some European countries. For people who are prescribed opioids, pharmacies offer an accessible, regular point-of-contact, providing a unique opportunity to address opioid prescription drugs risks.

OBJECTIVE

This project aimed to develop consensus-based, best practice statements for improving the safer use of prescription opioids through community pharmacy settings.

METHODS

The e-Delphi technique is used to obtain consensus from experts about issues where conclusive evidence is lacking, using multiple rounds of online participation. The investigator group identified an international group of potential participants with relevant expertise who were invited to the study, and asked to identify other experts for invitation. The e-Delphi process comprised three online rounds, involving (1) statement idea generation, (2) developing statement consensus, and (3) confirming and ranking statements.

RESULTS

A diverse group of 42 experts (76 % female, 6 countries) participated, comprising pharmacists (n = 24, 57 %), medical doctors of differing specialties (n = 12, 29 %), and/or researchers (n = 28, 67 %), with a mean of 15 years' professional experience (SD = 8.08). Eighty-five statements were initially developed in Round 1, and 78 were supported with amendments, with suggestions to merge and remove items in Round 2, resulting in 72 final statements which were all endorsed in Round 3. Items spanned seven themes: education, monitoring outcomes and risk, deprescribing and pain management, overdose education and naloxone, opioid agonist treatment, staff education, and overarching practices. Preferred terminology was determined in Round 2 and confirmed in Round 3.

CONCLUSIONS

Community pharmacies offer a unique opportunity to support the safer use of prescription opioids. These 72 best practice statements provide practical guidance on specific practices that pharmacists can undertake to support patients' safer use of prescription opioids and prevent or reduce harms from prescribed opioid use.

Perceptions of a naloxone leave behind program among emergency medical services personnel in Michigan, USA

Introduction

In 2020, Michigan implemented its first Naloxone Leave-Behind Program for Emergency Medical Service (EMS) field providers. Under the program, EMS field providers leave naloxone kits to individuals aged 15 or older they encounter in the field who have overdosed, who indicate they have a substance use disorder, or exhibit signs of opioid use and/or to bystanders, friends, or family that are present at the encounter.

Methods

Survey of EMS field providers and administrators to assess perspectives on the Michigan NLB program. Comparisons of perspectives between field providers and administrators working in EMS agencies operating in medical control authorities (MCAs) participating in the NLB program (i.e., participating agencies) with field providers and administrators working for EMS agencies serving non-participating MCAs.

Results

Most EMS field providers and administrators supported the Michigan NLB program. However, some were concerned about the unintended consequences of leaving behind naloxone, including the potential for recipients to use more drugs or be less likely to seek treatment. Perspectives of NLB program effectiveness were similar between EMS administrators and field providers. Participating administrators' top-cited barrier to implementation was convincing field providers to leave behind naloxone, while non-participating administrators were concerned with stocking naloxone kits.

Conclusions

Additional engagement and training to address concerns by EMS field providers and administrators about the benefits of the NLB program are needed to expand program participation intensity. Streamlining naloxone procurement and increasing messaging about free access to naloxone for participating in the program may help increase adoption.

Effects of Online Naloxone Training for Laypersons: An Extended-Baseline Assessment

Background: While laypersons can play a crucial role in administering naloxone in opioid overdoses, they must be recruited and trained to effectively manage overdose events as good Samaritans. This study aimed to examine the effectiveness of a technology-based intervention that recruited and trained laypersons to administer naloxone. Methods: Opioid Rapid Response System (ORRS) was an online recruitment and training intervention which capitalized on social cognitive theory and a digital media engagement model to mobilize laypersons to administer intranasal naloxone. ORRS was developed based on a randomized waitlisted controlled trial (N = 220). This secondary analysis is a within-group, extended-baseline assessment of the waitlisted group (n = 106), considering that they served as their own control prior to receiving the training. ORRS was conducted in five counties of Indiana with adults who did not self-identify as a certified first responder. Five indices were generated from 23 variables: knowledge of overdose signs, knowledge of overdose management, self-efficacy in responding, concerns about responding, and intent to respond. Paired t-test compared changes between 3 timepoints. Results: Three indices had significantly greater increases associated with training compared to extended baseline: recognizing opioid overdose signs (difference = 0.08; 95%CI = 0.02, 0.15; t = 2.48; p = 0.01); knowledge of overdose management (difference = 0.27; 95%CI = 0.18, 0.35; t = 5.99; p < 0.01); and self-efficacy in overdose management (difference = 0.68; 95%CI = 0.45, 0.91; t = 5.78; p < 0.01). Concerns related to overdose management significantly decreased as expected (difference = -1.53; 95%CI = -1.86, -1.21; t = -9.27; p < 0.01). Conclusions: ORRS provided strong support for self-efficacy, concerns, and knowledge related to overdose management, and the digital modality accelerates largescale dissemination.

Systematic literature review of the impact of psychiatric pharmacists

Introduction

Pharmacists focusing on psychotropic medication management and practicing across a wide variety of healthcare settings have significantly improved patient-level outcomes. The Systematic Literature Review Committee of the American Association of Psychiatric Pharmacists was tasked with compiling a comprehensive database of primary literature highlighting the impact of psychiatric pharmacists on patient-level outcomes.

Methods

A systematic search of literature published from January 1, 1961, to December 31, 2022, was conducted using PubMed and search terms based on a prior American Association of Psychiatric Pharmacists literature review. Publications describing patient-level outcome results associated with pharmacist provision of care in psychiatric/neurologic settings and/or in relation to psychotropic medications were included. The search excluded articles for which there was no pharmacist intervention, no psychiatric disorder treatment, no clinical outcomes, no original research, no access to full text, and/or no English-language version.

Results

A total of 4270 articles were reviewed via PubMed, with 4072 articles excluded based on title, abstract, and/or full text in the initial pass and 208 articles selected for inclusion. A secondary full-text review excluded 11 additional articles, and 5 excluded articles were ultimately included based on a secondary review, for a final total of 202 articles meeting the inclusion criteria. A comprehensive database of these articles was compiled, including details on their study designs and outcomes.

Discussion

The articles included in the final database had a wide range of heterogeneity. While the overall impact of psychiatric pharmacists was positive, the study variability highlights the need for future publications to have more consistent, standardized outcomes with stronger study designs.

Endogenous opiates and behavior: 2022

This paper is the forty-fifth consecutive installment of the annual anthological review of research concerning the endogenous opioid system, summarizing articles published during 2022 that studied the behavioral effects of molecular, pharmacological and genetic manipulation of opioid peptides and receptors as well as effects of opioid/opiate agonists and antagonists. The review is subdivided into the following specific topics: molecular-biochemical effects and neurochemical localization studies of endogenous opioids and their receptors (1), the roles of these opioid peptides and receptors in pain and analgesia in animals (2) and humans (3), opioid-sensitive and opioid-insensitive effects of nonopioid analgesics (4), opioid peptide and receptor involvement in tolerance and dependence (5), stress and social status (6), learning and memory (7), eating and drinking (8), drug abuse and alcohol (9), sexual activity and hormones, pregnancy, development and endocrinology (10), mental illness and mood (11), seizures and neurologic disorders (12), electrical-related activity and neurophysiology (13), general activity and locomotion (14), gastrointestinal, renal and hepatic functions (15), cardiovascular responses (16), respiration and thermoregulation (17), and immunological responses (18).

Temporal Reinforcement of Naloxone Training Results in Significant Retention of Anti-bias and Overdose-Response Knowledge

BACKGROUND

The opioid epidemic is an increasingly severe problem affecting public health and leading to significant economic burdens on healthcare systems. Overdose reversal training and de-stigmatization efforts are common strategies used to combat this epidemic. Nevertheless, healthcare professionals report a lack of confidence in administering naloxone and high stigmatization levels toward people with opioid use disorder (OUD). While one-time educational training reduces stigma and improves naloxone administration confidence, we previously demonstrated that knowledge retention at a three-month follow-up is reduced among a cohort of medical students. This study aimed to improve the effectiveness of opioid overdose awareness and reversal training (OOART) with a three-month follow-up abbreviated OOART (aOOART) booster video.

METHODS

Voluntary OOART was offered to first-year medical students (M1) at the Drexel University College of Medicine in 2022. At this training, 82 students completed a pre-training survey to establish a baseline knowledge and attitude toward people with OUD and their familiarity with the steps to reverse an opioid overdose. Following the hour-long training, 64 of 82 (79%) participants completed the post-training survey to measure the immediate retention of training information. After 2.5 months, students were randomly selected to receive a 6.5-minute aOOART booster video or serve as an unboosted control. Students in the booster and non-booster cohorts then completed a three-month follow-up survey.

RESULTS

 Students who received the aOOART booster had significantly increased opioid reversal knowledge scores compared to non-boosted control students at the three-month follow-up. The aOOART booster resulted in a retention of the lowered stigma, and participants expressed a higher willingness to respond to an opioid overdose compared to participants who did not receive the booster video at the three-month follow-up.

CONCLUSIONS

 This study shows that an aOOART booster method improves knowledge retention following initial OOART. Further, the aOOART booster video served to maintain participants' reduced stigma toward people with OUD and maintained participants' willingness to respond to an opioid overdose. These results support the incorporation of an abbreviated, periodic OOART reinforcement video into opioid overdose response training nationwide. We believe this "booster video" approach is a novel and effective method to improve healthcare professionals' and medical student preparedness to render appropriate care to people with OUD.

A longitudinal study of naloxone opioid overdose awareness and reversal training for first-year medical students: specific elements require reinforcement

Background

The opioid epidemic is a progressively worsening public health crisis that continues to impact healthcare system strategies such as overdose reversal and destigmatization. Even among healthcare professionals, there remains a lack of confidence in naloxone administration and a prevalence of stigma. While training can play a major impact in reducing these shortcomings, the long-term effectiveness has yet to be characterized in training healthcare professionals. This study examined the long-term retention of opioid overdose awareness and reversal training (OOART) by evaluating performance at two-time intervals, immediately post-training and at a 3-month follow-up.

Methods

Voluntary training was offered to first-year (M1) medical students at the Drexel University College of Medicine in 2021. At this training, 118 students completed training, 95 completed the post-training survey, and 42 completed the 3-month follow-up.

Results

Opioid reversal knowledge questions assessed significantly increased scores post-training and at the 3-month follow-up. In three of the attitude questions, scores were improved at both follow-up timepoints. In addition, three attitude questions indicating a participant’s confidence to respond to an opioid overdose situation increased directly after the training, but regressed at the 3-month follow-up. The remaining questions did not show any statistical difference across the survey intervals.

Conclusions

This study establishes that while OOART provides participants with the knowledge of how to respond to an opioid overdose, the retention of this knowledge at a 3-month interval is reduced. The results were mixed for longitudinal assessment of participant’s attitudes toward people with opioid use disorder. Some positive increases in attitudes were retained at the 3-month interval, while others trended back toward pre-training levels. These results support the effectiveness of the training but also provide evidence that OOART must be reinforced often.
