Reducing the harms of xylazine: clinical approaches, research deficits, and public health context.

OBJECTIVES: Xylazine has emerged as a consistent part of the unregulated drug supply in recent months. We discuss major domains of xylazine's harm, current knowledge deficits, clinical and harm reduction strategies for minimizing harm, and xylazine's public health and policy context. As an interdisciplinary team from across the USA, we have pooled our knowledge to provide an overview of xylazine's current and emerging contexts. METHODS: To inform this essay, the pertinent literature was reviewed, clinical knowledge and protocols were shared by multiple clinicians with direct expertise, and policy and public health context were added by expert authors. RESULTS: We describe xylazine's major harm domains-acute poisoning, extended sedation, and wounds, along with anemia and hyperglycemia, which have been reported anecdotally but lack as clear of a connection to xylazine. Current successful practices for xylazine wound care are detailed. Understanding xylazine's epidemiology will also require greater investment in drug checking and surveillance. Finally, approaches to community-based wound care are discussed, along with an orientation to the larger policy and public health context. CONCLUSIONS: Addressing the harms of xylazine requires interdisciplinary participation, investment in community-based harm reduction strategies, and improved drug supply surveillance. The relatively unique context of xylazine demands buy-in from public health professionals, harm reduction professionals, clinicians, basic science researchers, policymakers and more.

Description and Evaluation of a Pilot Advanced Pharmacy Practice Experience in Addiction Medicine.

Objective. To assess the impact of a pilot advanced pharmacy practice experience (APPE) on fourth-year (P4) Doctor of Pharmacy (PharmD) students' knowledge and confidence related to substance use disorder, harm reduction, and co-occurring psychiatric conditions.Methods. Beginning in 2020, a 62-item assessment was developed and administered to P4 students at the beginning and end of the six-week APPE. The assessment tested knowledge in 10 content areas related to substance use disorder, harm reduction, and co-occurring disorders. Students also ranked their confidence in providing care related to each content area. The post-assessment included a free-text (open-ended) item to provide feedback on the APPE experience. Descriptive statistics and paired t tests were used to analyze the data.Results. Complete pre- and post-assessments were obtained from all participating students (N=7). The mean cumulative knowledge score increased from 55.2% to 81.5%, and the mean cumulative confidence score improved from 34.2% to 81.8%. Free-text responses garnered positive feedback from students, who indicated that the APPE allowed them to immerse themselves in all stages of the recovery process, gain confidence in presentation skills with patients, and solidify their passion for addiction medicine.Conclusion. A novel APPE in addiction medicine addressed a current gap in pharmacy education, earned positive evaluations from student pharmacists, increased student knowledge and confidence related to substance use disorder, harm reduction, and co-occurring disorders, and supported the development of new interprofessional collaborations. United States colleges of pharmacy that do not yet offer APPEs in this clinical domain should consider this model.

A qualitative exploration of unintentional versus intentional exposure to fentanyl among people who use drugs in Austin, TX.

BACKGROUND: The prevalence of deaths involving synthetic opioids has historically been lower in Texas than most U.S. states but more than quadrupled from January 2020 to January 2022. This paper explores the emergence of fentanyl in a drug supply where black tar heroin predominates, a factor considered protective against fentanyl adulteration, through the perspectives of people who use drugs (PWUD). OBJECTIVES: We describe experiences of unintentional exposure to fentanyl, illustrate how some people identify fentanyl in their supply, and present harm reduction strategies that PWUD use to avoid overdose. METHODS: Thirty rapid assessment interviews were conducted in July 2021 at 2 mobile outreach sites of a harm reduction organization in Austin, Texas. The brief semistructured interviews were designed to assess participant fentanyl exposure experiences. RESULTS: Participants were clients who reported using heroin or fentanyl in the past week and had lived in Texas for at least 6 months. Seventeen participants identified as male, 10 as female, and 3 as nonbinary. Half identified as white; other participants were Latinx (6), black (2), American Indian (1), and mixed race (6). Two-thirds were unhoused or in transitional housing. The drug supply in Texas has evolved; most participants reported that the heroin and other drugs they obtained contain fentanyl. Participants detected differences by observing changes in the physical characteristics of the drug, experiencing unexpected effects, and using fentanyl test strips. Many had been unintentionally exposed to fentanyl and expressed concerns about fentanyl's presence. The presence of fentanyl had negative unintended consequences for participants, including adverse effects and developing a dependence on opioids. CONCLUSION: PWUD in Austin, Texas, report increasing prevalence of unintentional fentanyl exposure, despite the predominance of black tar heroin. Pharmacists can provide crucial supplies and education to safeguard the health of this vulnerable population.

A wound care and immunization needs assessment for participants of a mobile syringe services program in Austin, TX.

BACKGROUND: People who inject drugs (PWID) are subject to injection-related harm, including skin and soft tissue infections. Syringe services programs (SSPs) provide sterile syringes, disposal of used syringes, and other supportive services. Given their contact and credibility with PWID, SSPs could facilitate triage and treatment of wounds and access to immunizations for communicable diseases. OBJECTIVE: This work aimed to assess wound care and immunization needs among participants accessing mobile SSP services in Austin, TX. METHODS: A 21-item mixed-methods survey was created to assess frequency and severity of wounds, wound care approaches, and vaccination status. Participants were included if they reported injection drug use and experienced a related wound in the previous 6 months. Interview sections included screening, demographics, wound care, and immunization status. RESULTS: A total of 21 participants completed the semistructured interview. A majority identified as male (n = 13, 61.9%), white (n = 12, 57.1%), and were unhoused (n = 12, 57.1%). The primary drug of injection was heroin alone (n = 14, 66.7%). Many avoided seeking wound care from health care providers (n = 16, 76.2%) owing to stigmatization (n = 13, 61.9%) and previous negative experiences (n = 7, 33.3%). Self-treatment of wounds included over-the-counter medications (n = 10, 47.6%), over-the-counter supplies (n = 10, 47.6%), and antibiotics (n = 9, 42.8%). In the past 5 years, few had received vaccination for hepatitis A and B (n = 3, 14.3%) or tetanus (n = 7, 33.3%), and many expressed interest in receiving vaccinations through the SSP. Interest for other expanded services included access to antibiotics, an on-site provider, wound care supplies, and education. CONCLUSIONS: PWID may avoid professional health care for wound care or immunizations owing to perceived stigma. Expanding availability of wound care services and immunizations directly through mobile SSPs is desired by participants and could positively affect public health.

Availability of buprenorphine/naloxone films and naloxone nasal spray in community pharmacies in 11 U.S. states.

BACKGROUND: Prompt access to prescribed buprenorphine/naloxone films (BUP/NX) and naloxone nasal spray (NNS) is vital for patients with opioid use disorder (OUD), but multiple studies have documented pharmacy-level barriers. METHODS: A cross-sectional secret shopper telephone audit was conducted in a sample of 5734 actively licensed pharmacies in 11 U.S. states from May 2020-April 2021. Primary outcomes included availability of 14 generic BUP/NX 8/2 mg and one unit of NNS 4 mg. Outcomes were compared by pharmacy type, county metropolitan status, state Medicaid expansion status, and state drug overdose death rate. RESULTS: Data from 4984 pharmacies (3402 chain and 1582 independent) were analyzed. Both medications were available in 41.2 % of pharmacies, BUP/NX was available in 48.3%, and NNS was available in 69.5%. Chain pharmacies were significantly more likely than independent pharmacies to have both medications available, to have each medication available individually, and to be willing to order BUP/NX. Pharmacies in metropolitan counties were more likely to have BUP/NX available than pharmacies in non-metropolitan counties, pharmacies in Medicaid expansion states were more likely to have both medications available and to have NNS available than pharmacies in non-expansion states, and pharmacies in states with high drug overdose death rates were more likely to have NNS available than pharmacies in states with low drug overdose death rates. CONCLUSIONS: BUP/NX and NNS are not readily accessible in many U.S. pharmacies. Deficits in access are most pronounced in independent pharmacies, though county- and state-level factors may also influence availability of these essential medications.

Policies regarding use of medications for opioid use disorder in professional recovery programs: A scoping review.

Background: In the U.S., medications for opioid use disorder (MOUD) include methadone, buprenorphine, and naltrexone. Despite substantial evidence of efficacy, the use of MOUD by health professionals remains controversial. This scoping review sought to identify and describe policies related to the use of MOUD by physicians, pharmacists, and nurses in professional health programs (PHP). Methods: A systematic search of PubMed, Medline, Web of Science, and Google Scholar was performed in August 2020 to identify pertinent articles from the U.S. which were then evaluated for inclusion by a team of trained reviewers. Results: Nine articles were ultimately identified for inclusion, and their years of publication ranged from 1984 to 2012. The treatment of physicians was addressed in seven articles, nurses in four, and pharmacists in two. Data from one veterinarian and several dentists could not be disaggregated from three studies. Naltrexone was the most commonly accepted form of MOUD within PHPs. A 2011 survey of physician and nurse PHP administrators found that 11/22 (50%) physician programs and 15/33 (45%) nursing programs forbade practice reentry while taking buprenorphine with the remainder indicating it could be allowed under some circumstances. The use of methadone within PHPs was extremely rare, and no specific details regarding PHP policies related to its use or practice reentry could be identified. No articles reported specifically on practice reentry policies for pharmacists. Conclusions: This scoping review identified one article detailing explicit policies concerning MOUD use in the target professions. Implicit policies extrapolated from other articles found that naltrexone was the most commonly accepted form of MOUD, with methadone and buprenorphine being avoided due to dubious concerns of impairment. A unified, contemporary, comprehensive survey of current PHP policies and evaluation of actual treatment data to ascertain real-world practices is needed.

Availability of buprenorphine/naloxone films and naloxone nasal spray in community pharmacies in Texas, USA.

BACKGROUND AND AIMS: Patients with opioid use disorder (OUD) must be able to obtain prescribed buprenorphine/naloxone films (BUP/NX) and naloxone nasal spray (NNS) from a pharmacy promptly to reduce risk for a recurrence of use and subsequent morbidity and mortality. Telephone audits have identified concerning gaps in availability of NNS within US pharmacies, but the availability of BUP/NX has not been rigorously evaluated. This study estimated the availability of BUP/NX and NNS in the US state of Texas and compared availability by pharmacy type and metropolitan status. DESIGN: A cross-sectional telephone audit with a secret shopper approach conducted from 18 May 2020 to 7 June 2020. Setting and Participants A random sample of 800 of 5078 (16%) community pharmacies licensed with the Texas State Board of Pharmacy. MEASUREMENTS: Primary outcomes included availability of a 1-week supply of generic BUP/NX 8/2 mg films and a single unit of NNS 4 mg, overall and by pharmacy type. Secondary outcomes included willingness and estimated time-frame to order BUP/NX if unavailable. FINDINGS: Data from 704 pharmacies (471 chain, 233 independent) were included for analyses. Of these, 34.1% of pharmacies (45.0% of chains versus 12.0% of independents, P < 0.0001) were willing and able to dispense a 1-week supply of generic BUP/NX and a single unit of NNS. BUP/NX alone was available in 42.2% of pharmacies (52.4% of chains versus 21.5% of independents, P < 0.0001). NNS alone was available in 60.1% of pharmacies (77.9% of chains versus 24.0% of independents, P < 0.0001). Of the 397 pharmacies with generic BUP/NX unavailable, 62.2% of pharmacies (73.9% of chains versus 48.0% of independents, P < 0.0001) indicated willingness to order. CONCLUSIONS: Most pharmacies in Texas do not appear to be willing and able to dispense prescribed buprenorphine/naloxone films and naloxone nasal spray to patients with opioid use disorder in a timely manner. Deficiencies in availability are markedly more pronounced in independent pharmacies compared with chain pharmacies.
