Comparison of naloxone prescribing patterns due to educational outreach conducted by full-time and part-time academic detailers at the U.S. Veterans Health Administration

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).

Naloxone prescribing practices in the Military Health System before and after policy implementation

Supplemental Digital Content is Available in the Text. Naloxone prescribing rates for patients meeting the criteria for risk indicators in the U.S. Military Health System increased from January 2017 to February 2021. Bayesian time series analyses indicated that increases in naloxone prescribing after the release of 2 Defense Health Agency policies (June 2018) were not significantly different than forecasted.

Naloxone dispensing among the commercially insured population in the United States from 2015 to 2018

The Centers for Disease Control and Prevention's (CDC) Guideline for Prescribing Opioids for Chronic Pain recommends that providers consider co-prescribing naloxone when factors that increase the risk of overdose are present. Naloxone is an opioid receptor antagonist that counteracts the effects of an opioid overdose. This paper explores trends in naloxone dispensing and out-of-pocket costs among commercially insured individuals in the United States. Administrative claims data from the IBM Watson Health MarketScan database are analyzed to assess trends in naloxone dispensing from 2015 to 2018. Descriptive statistics on concurrent dispensing of naloxone with opioid analgesics are performed among several at-risk populations. The rate of commercially insured individuals being co-dispensed naloxone increased between 2015 and 2018 across all population sub-groups. In 2018, 16.2 individuals were co-dispensed naloxone for every 1000 receiving an opioid dosage ≥ 90 MME/day compared to 0.9 in 2015, 27.6 individuals were co-dispensed naloxone for every 1000 concurrently dispensed benzodiazepines and an opioid dosage ≥ 90 MME/day compared to 7.6 in 2015, and 43.7 individuals were co-dispensed naloxone for every 1000 receiving an opioid dosage ≥90 MME/day with a past overdose compared to 17.6 in 2015. Median out-of-pocket cost for naloxone increased from $12 in 2015 to $25 in 2018. Despite increases in naloxone dispensing from 2015 to 2018, the provision of naloxone to the commercially insured population remains low. Opportunities remain to increase the supply of naloxone to at-risk populations. Considering ways to reduce out-of-pocket costs associated with naloxone may be a potential strategy to increase access to this life-saving drug.

Saving Lives: The Veterans Health Administration (VHA) Rapid Naloxone Initiative

BACKGROUND

The United States is in the midst of an opioid epidemic within the COVID-19 pandemic, and veterans are twice as likely to die from accidental overdose compared to non-veterans. This article describes the Veterans Health Administration (VHA) Rapid Naloxone Initiative, which aims to prevent opioid overdose deaths among veterans through (1) opioid overdose education and naloxone distribution (OEND) to VHA patients at risk for opioid overdose, (2) VA Police naloxone, and (3) select automated external defibrillator (AED) cabinet naloxone.

METHODS

VHA has taken a multifaceted, theory-based approach to ensuring the rapid availability of naloxone to prevent opioid overdose deaths. Strategies targeted at multiple levels (for example, patient, provider, health care system) have enabled synergies to speed diffusion of this lifesaving practice.

RESULTS

As of April 2021, 285,279 VHA patients had received naloxone from 31,730 unique prescribers, with 1,880 reported opioid overdose reversals with naloxone; 129 VHA facilities had equipped 3,552 VA Police officers with naloxone, with 136 reported opioid overdose reversals with VA Police naloxone; and 77 VHA facilities had equipped 1,095 AED cabinets with naloxone, with 10 reported opioid overdose reversals with AED cabinet naloxone. Remarkably, the COVID-19 pandemic had minimal impact on naloxone dispensing to VHA patients.

CONCLUSION

The VHA Rapid Naloxone Initiative saves lives. VHA is sharing many of the tools and resources it has developed to support uptake across other health care systems. Health care systems need to work together to combat this horrific epidemic within a pandemic and prevent a leading cause of accidental death (opioid overdose).

Patient, prescriber, and Community factors associated with filled naloxone prescriptions among patients receiving buprenorphine 2017-18

BACKGROUND

Prescribing naloxone to patients at increased opioid overdose risk is a key component of opioid overdose prevention efforts, but little is known about naloxone fills among patients receiving buprenorphine for opioid use disorder, one such high risk group.

METHODS

This retrospective cross-sectional study used de-identified pharmacy claims representing 90% of all prescriptions filled at retail pharmacies in 50 states and the District of Columbia. We performed a multivariable logistic regression to examine filled naloxone prescriptions among patients receiving buprenorphine treatment and assessed how filled naloxone prescriptions vary by patient, prescriber, and community characteristics.

RESULTS

Filled naloxone prescriptions occurred among 4.5% of buprenorphine treatment episodes. Episodes paid through Medicaid (aOR 2.40, 95%CI 2.33-2.47) and Medicare (aOR 1.53, 95%CI 1.46-1.60) had higher odds of filled naloxone prescriptions than commercial insurance episodes. Compared to episodes where the primary prescriber was an adult primary care physician, odds of filling a naloxone prescription were higher among episodes prescribed by addiction specialists (aOR 1.30, 95% CI 1.24-1.37) and physician assistants/nurse practitioners (aOR 1.57, 95% CI 1.53-1.61).

CONCLUSIONS

Prescribing naloxone to patients receiving buprenorphine represents a tangible clinical action that can be taken to help prevent opioid overdose deaths. However, despite recommendations to co-prescribe naloxone to patients at increased risk for opioid overdose, rates of filling naloxone prescriptions remain low among patients dispensed buprenorphine. States, insurers, and health systems should consider implementing strategies to facilitate increased co-prescribing of naloxone to at-risk individuals.

Pharmacologic Considerations for Opioid Use in Kidney Disease

Individuals with kidney disease have a high prevalence of chronic noncancer pain. Although opioids are not a recommended treatment option for chronic noncancer pain in the general population, a higher percentage of individuals with kidney disease receive opioid prescriptions for chronic pain. Individuals with kidney disease have an increased risk for opioid adverse events because of changes related to kidney disease progression, normative aging, and the pharmacology of opioid medications. Despite the frequent prescription of opioids for chronic noncancer pain among those with kidney disease, there are no guidelines for opioid management in this population. This article reviews the pharmacologic challenges of opioid use in relation to the physiologic changes occurring in kidney disease and normative aging. We highlight how understanding opioid pharmacology and human physiology can support safe practices of opioid management in patients with kidney disease who require opioids for chronic noncancer pain.
