Shifting Perspectives: Harm Reduction Staff Perceptions of Drug Checking Implementation
Background: As the overdose crisis continues to devastate communities, expanding access to harm reduction services, such as drug checking, is essential. Drug checking services (DCS) enable people who use drugs (PWUD) to identify the likely active ingredients within their substances, supporting safer use and reducing overdose risk. However, implementing DCS in community settings may encounter barriers such as stigma, legal ambiguity, and organizational constraints. This study examines harm reduction staff perspectives on the implementation and delivery of a community-based DCS program in Michigan. Methods: This study explored the perceptions of staff from a harm reduction organization before and after implementing Michigan’s first community-based DCS using Fourier-Transform Infrared spectroscopy. Six focus groups, each composed of 2 to 5 staff members, were conducted before and after implementing DCS. Rapid qualitative methods, informed by the Consolidated Framework for Implementation Research, were used for analysis. Results: Prior to implementation, staff anticipated that DCS would empower PWUD and provide crucial drug supply information to communities. Staff also believed that strong relationships with PWUD and effective service integration would facilitate uptake. Post-implementation, staff noted there was considerable engagement with DCS among PWUD, enhanced by dissemination via peer networks and strategic communication approaches. However, staff encountered several barriers to smooth implementation, including ongoing concerns about legal risks and criminalization, as well as organizational capacity constraints. Conclusion: Findings from this study highlight the need for legal protections, adequate staffing, and community support to sustain and expand drug checking programs.

Using RE-AIM Framework to Evaluate Recovery Opioid Overdose Team Plus: A Peer-Led Post-overdose Quick Response Team
Peer recovery coaches utilize their lived experiences to support overdose survivors, a role gaining prominence across communities. A convergent mixed methods design, informed by the RE-AIM (Reach, Effectiveness, Adoption, Implementation, Maintenance) framework, was used to evaluate the Recovery Opioid Overdose Team Plus (ROOT +), through an iterative evaluation using web-based surveys and qualitative interviews. Reach: Over 27 months, ROOT + responded to 83% of suspected overdose referrals (n = 607) and engaged with 41% of survivors (n = 217) and 7% of survivors’ family/friends (n = 38). Effectiveness: Among those initially engaged with ROOT +, 36% of survivors remained engaged, entered treatment, or were in recovery at 90 days post-overdose (n = 77). Adoption: First responders completed 77% of ROOT + referrals (n = 468). Implementation: Barriers included lack of awareness of ROOT + , working phones, and access to treatment from community partner interviews (n = 15). Maintenance: Adaptations to ROOT + were made to facilitate implementation. Peer-led teams are promising models to engage with overdose survivors.

Effectiveness of take ACTION online naloxone training for law enforcement officers
Background: Training law enforcement officers (LEOs) to administer naloxone is a recommended strategy to reduce overdose deaths in the United States. To achieve this, an evidence-based and scalable naloxone training curriculum that is easy to use and readily scalable is needed. Convenient web-based training is a flexible method for delivering educational interventions particularly for LEOs who have irregular or shifting schedules. This study examined the effectiveness of a comprehensive web-based naloxone training that was created in partnership with LEOs on their knowledge, confidence, and attitudes regarding naloxone. Methods: From May 2019 to September 2020, five law enforcement departments from Michigan participated in web-based naloxone training. A total of 182 LEOs (77% male) were in the final sample based on matching pre-and post-test surveys. LEOs were assessed on knowledge, confidence, and attitudes towards naloxone. Negative binomial and Poisson regression was conducted to assess associations between knowledge, confidence, and attitudes towards naloxone before and after training. Results: Significant improvements in overdose knowledge and confidence were revealed across all departments with median (IQR) total composite scores for knowledge increasing from 35 (32, 37) to 40 (39, 42) (p < 0.01) and confidence increasing from 18.5 (15, 20) to 20 (20, 25) (p < 0.01). Median (IQR) attitude scores did not change. Conclusion: Our web-based naloxone training was effective in improving knowledge and confidence for LEOs but did not significantly improve LEOs attitudes towards naloxone across most departments. The web-based format is readily scalable and quickly disseminated and meets the immediate need for LEO overdose training. Additional intervention is needed to address the negative attitudes of LEOs regarding naloxone.

Web-Based Naloxone Training for Law Enforcement Officers: A Pilot Feasibility Study
Background: Training and equipping law enforcement officers (LEOs) with naloxone to reverse overdoses is one national preventive strategy to reduce overdose deaths. Web-based interventions can offer convenience, flexibility of use, and can be readily disseminated. Objectives: This paper describes our community–academic partnership in developing and evaluating a web-based naloxone training for LEOs. Methods: Using a community-engaged approach, we created a web-based training (www.overdoseaction.org) and conducted a pilot feasibility test using surveys and individual interviews with ten LEOs. Results: The median time to complete the web-based naloxone training, including the pre- and post-tests, was 45 minutes (range, 37–80 minutes). A significant difference in the pretest and post-test scores of overdose knowledge was observed. The LEOs found the training helpful in responding to overdoses and sustained their attention. Conclusions: This study demonstrates the feasibility of a web-based naloxone training for LEOs that can be easily disseminated and alternative to in-person trainings.

Prescription Opioid Misuse in Older Adult Surgical Patients
The United States and many other developed nations are in the midst of an opioid crisis, with consequent pressure on prescribers to limit opioid prescribing and reduce prescription opioid misuse. This review addresses prescription opioid misuse for older adult surgical populations. We outline the epidemiology and risk factors for persistent opioid use and misuse in older adults undergoing surgery. We also address screening tools and prescription opioid misuse prevention among vulnerable older adult surgical patients (e.g., older adults with a history of an opioid use disorder), followed by clinical management and patient education recommendations. A significant plurality of older adults engaged in prescription opioid misuse obtain opioid medication for misuse from health providers. Thus, nurses can play a critical role in identifying those older adults at a higher risk for misuse and deliver quality care while balancing the need for adequate pain management against the risk for prescription opioid misuse.

Factors associated with naloxone availability and dispensing through Michigan’s pharmacy standing order
Background: Pharmacy standing order policies allow pharmacists to dispense naloxone, thereby increasing access to naloxone. Objectives: To describe pharmacy standing order participation and associations of pharmacy and community characteristics that predict naloxone availability and dispensing across eight counties in Michigan. Methods: We conducted a telephone survey of 662 standing order pharmacies with a response rate of 81% (n = 539). Pharmacies were linked with census tract-level demographics, overdose fatality rates, and dispensing data. County maps were created to visualize pharmacy locations relative to fatality rates. Regression models analyzed associations between pharmacy type, neighborhood characteristics, fatality rates, and these outcomes: naloxone availability, having ever dispensed naloxone, and counts of naloxone dispensed. Results: The prevalence of standing order pharmacies was 54% (n = 662/1231). Maps revealed areas with higher fatality rates had fewer pharmacies participating in the standing order or lacked any pharmacy access. Among standing order pharmacies surveyed, 85% (n = 458/539) had naloxone available and 82% had ever dispensed (n = 333/406). The mean out-of-pocket cost of Narcan® was $127.77 (SD: 23.93). National chains were more likely than regional chains to stock naloxone (AOR = 3.75, 95%CI = 1.77, 7.93) and to have ever dispensed naloxone (AOR 3.02, 95%CI = 1.21,7.57). Higher volume of naloxone dispensed was associated in neighborhoods with greater proportions of public health insurance (IRR = 1.38, 95%CI = 1.21, 1.58) and populations under 44 years old (IRR = 1.24, 95%CI = 1.04, 1.48). There was no association with neighborhood overdose fatality rates or race in regression models. Conclusion: As deaths from the opioid epidemic continue to escalate, efforts to expand naloxone access through greater standing order pharmacy participation are warranted.

Law Enforcement Perceptions About Naloxone Training and Its Effects Post-Overdose Reversal
Background: Law enforcement officers (LEOs) often are the first responders to arrive at a scene of an opioid overdose. Thus, equipping LEOs as first responders with naloxone is necessary to prevent overdose deaths and a recommended strategy. However, little is known about how LEOs perceive naloxone training and their feelings after using naloxone to save a life. It is important to understand LEOs' experiences with naloxone so as to develop additional training materials that are relevant to the LEO experience. Methods: A descriptive exploratory study was conducted to explore the perceptions of LEOs about using naloxone in the field and to identify areas that should be included in future naloxone trainings. Interview data were obtained through face-to-face interviews with LEOs (N = 14) and analyzed using manifest content analysis. Results: LEOs changed their attitudes and beliefs toward naloxone after receiving training and experiencing a successful resuscitation. The change in attitudes was enhanced after saving a life. However, misconceptions about naloxone and lack of understanding about disease of addiction persisted even after training. Conclusion: Future naloxone curriculum could benefit from additional lessons on the stigma of addiction, the disease of addiction, misconceptions about the safety of naloxone, strategies for postoverdose responses, and the role naloxone, which might play in a hopeful recovery.
