Pharmacists' experiences with a statewide naloxone standing order program in Massachusetts: a mixed methods study

Correlates of stocking naloxone: a cross-sectional survey of community pharmacists

BACKGROUND

Provision of take-home naloxone (THN) and overdose education reduces opioid-related mortality. In Australia, from July 2022, all Australian community pharmacies were eligible to supply naloxone for free through the national THN Program.

AIM

This study aimed to identify naloxone stocking rates and correlates of stocking naloxone across Australian pharmacies.

METHOD

Data were collected from a representative sample of Australian pharmacists in Victoria, New South Wales, Queensland and Western Australia via an online survey. Data collected included pharmacy and pharmacist characteristics and services offered within the pharmacy, including needle and syringe programs, opioid agonist treatment (OAT) and stocking naloxone. Binary probit regression analysis was used to identify correlates of stocking naloxone after controlling for key covariates.

RESULTS

Data from 530 pharmacists were analysed. In total, 321 pharmacies (60.6%) reported stocking naloxone. Chain pharmacies and pharmacies that provided OAT had a greater probability of stocking naloxone (B = 0.307, 95%CI: [0.057, 0.556], and B = 0.543, 95%CI: [0.308, 0.777] respectively). Most (61.7%) pharmacists felt comfortable discussing overdose prevention with patients who use prescription opioids, and this comfort was associated with a higher probability of stocking naloxone (B = 0.392, 95%CI: 0.128, 0.655). Comfort discussing overdose prevention with people who use illicit opioids was lower (49.4%) and was not associated with stocking naloxone.

CONCLUSION

There is scope to increase stocking of naloxone and comfort with overdose prevention, particularly through addressing comfort working with higher risk groups such as people who use illicit opioids.

Community pharmacists' naloxone counseling: A theory-informed qualitative study

BACKGROUND

Opioid-related overdose (ORO) deaths have reached a record high in the United States. Naloxone is an opioid antagonist that can rapidly reverse an opioid overdose. Pharmacists are in an ideal position to provide naloxone and related counseling, given their accessibility and expertise. However, minimal research is available on community pharmacists' naloxone counseling.

OBJECTIVES

The aim of this study was to investigate Georgia community pharmacists' naloxone counseling as well as explore their attitudes, subjective norms, and perceived behavioral control toward counseling.

METHODS

Semi-structured telephone interviews were conducted to elicit pharmacists' beliefs and practices regarding naloxone counseling. The interviews were guided by open-ended questions based on the theory of planned behavior (TPB). Thematic analysis was performed to identify the modal salient beliefs expressed by the pharmacists. The Consolidated Criteria for Reporting Qualitative Research was used to report the study findings.

RESULTS

A total of 12 community pharmacists participated. Pharmacists held mixed attitudes toward naloxone counseling. While they recognized it as a vital part of their profession to prevent ORO deaths, they also expressed concerns about offending patients. Regarding normative beliefs, pharmacists identified several groups, including regulatory agencies (e.g., Board of Pharmacy, CDC), managers, news/media, patients, and doctors, influencing their provision of naloxone counseling. Facilitators to counseling included receiving naloxone training and having access to counseling guidelines and resources. Reimbursement issues, high costs of naloxone, and lack of patient awareness were the most commonly cited barriers. Pharmacists reported participating in counseling and providing information on identifying signs of opioid overdose and administering naloxone.

CONCLUSIONS

The TPB is a useful framework for understanding community pharmacists' beliefs and practices regarding naloxone counseling. Capitalizing on facilitators and targeting barriers related to pharmacists' reimbursement issues, high costs of naloxone, and increasing patients' awareness of naloxone use and benefits may enhance pharmacists' naloxone counseling.

Association of Implementation of Postoverdose Outreach Programs With Subsequent Opioid Overdose Deaths Among Massachusetts Municipalities

Importance

Nonfatal opioid overdose is the leading risk factor for subsequent fatal overdose and represents a critical opportunity to reduce future overdose and mortality. Postoverdose outreach programs emerged in Massachusetts beginning in 2013 with the main purpose of linking opioid overdose survivors to addiction treatment and harm reduction services.

Objective

To evaluate whether the implementation of postoverdose outreach programs among Massachusetts municipalities was associated with lower opioid fatality rates compared with municipalities without postoverdose outreach programs.

Design, Setting, and Participants

This retrospective interrupted time-series analysis was performed over 26 quarters (from January 1, 2013, through June 30, 2019) across 93 municipalities in Massachusetts. These 93 municipalities were selected based on a threshold of 30 or more opioid-related emergency medical services (EMS) responses in 2015. Data were analyzed from November 2021 to August 2022.

Exposures

The main exposure was municipality postoverdose outreach programs. Municipalities had various program inceptions during the study period.

Main Outcomes and Measures

The primary outcome was quarterly municipal opioid fatality rate per 100 000 population. The secondary outcome was quarterly municipal opioid-related EMS response (ambulance trips) rates per 100 000 population.

Results

The mean (SD) population size across 93 municipalities was 47 622 (70 307), the mean (SD) proportion of female individuals was 51.5% (1.5%) and male individuals was 48.5% (1.5%), and the mean (SD) age proportions were 29.7% (4.0%) younger than 25 years, 26.0% (4.8%) aged 25 to 44 years, 14.8% (2.1%) aged 45 to 54 years, 13.4% (2.1%) aged 55 to 64 years, and 16.1% (4.4%) aged 65 years or older. Postoverdose programs were implemented in 58 municipalities (62%). Following implementation, there were no significant level changes in opioid fatality rate (adjusted rate ratio [aRR], 1.07; 95% CI, 0.96-1.19; P = .20). However, there was a significant slope decrease in opioid fatality rate (annualized aRR, 0.94; 95% CI, 0.90-0.98; P = .003) compared with the municipalities without the outreach programs. Similarly, there was a significant slope decrease in opioid-related EMS response rates (annualized aRR, 0.93; 95% CI, 0.89-0.98; P = .007). Several sensitivity analyses yielded similar findings.

Conclusions and Relevance

In this study, among Massachusetts municipalities with high numbers of opioid-related EMS responses, implementation of postoverdose outreach programs was significantly associated with lower opioid fatality rates over time compared with municipalities that did not implement such programs. Program components, including cross-sectoral partnerships, operational best practices, involvement of law enforcement, and related program costs, warrant further evaluation to enhance effectiveness.

Impact of a Multicomponent Educational Intervention on Community Pharmacy-Based Naloxone Services Implementation: A Pragmatic Randomized Controlled Trial

BACKGROUND

Despite US naloxone access laws, community pharmacists lack training and confidence in providing naloxone.

OBJECTIVE

To assess the impact of the Empowering Community Pharmacists program on pharmacists' knowledge, perceived barriers, attitudes, confidence, and intentions regarding naloxone services implementation, as well as naloxone prescriptions dispensed.

METHODS

A 3-month pragmatic randomized controlled trial was conducted from December 2018 to March 2019. Alabama community pharmacists were recruited by mail, email, phone, and fax and randomized to intervention (monthly resources/reminders + educational webinar) or control (monthly reminders only). Outcome measures were assessed via online surveys at baseline (T1), immediately post-intervention (T2), and 3 months post-intervention (T3), including naloxone knowledge (%correct); perceived barriers, attitudes, confidence, and intention regarding naloxone services implementation (7-point Likert-type scale; 1 = strongly disagree, 7 = strongly agree); and number of naloxone prescriptions dispensed. Mean differences between control and intervention from T1 to T3 were assessed using 2-way mixed analysis of variance and adjusted analyses were conducted using generalized estimating equations with negative binomial distribution to assess associations between variables.

RESULTS

Of 55 participants (n = 27 intervention, n = 28 control), most were female (80.3%), white (80.6%), in independently owned pharmacies (39.1%). Increases in mean [SD] confidence (5.52 [1.03]-6.16 [0.74], P < 0.0005) and intention (5.35 [1.51]-6.10 [0.96], P = 0.023) occurred from pre- to post-program within the intervention group and were statistically significant compared with control (confidence P = 0.016, intention P = 0.014). Confidence (exp(β) = 1.46, P = 0.031) and perceived barriers (exp(β) = 0.75, P = 0.022) were associated with number of naloxone prescriptions dispensed.

CONCLUSION AND RELEVANCE

The Empowering Community Pharmacists program improved community pharmacists' confidence and intention regarding naloxone services implementation. Other states can adapt program elements according to their laws.

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.

If we build it, will they come? Perspectives on pharmacy-based naloxone among family and friends of people who use opioids: a mixed methods study

BACKGROUND

Expanding access to the opioid antagonist naloxone to reduce overdose mortality is a public health priority in the United States. Naloxone standing orders (NSOs) have been established in many states to increase naloxone dispensing at pharmacies, but increased pharmacy access does not ensure optimal uptake among those likely to witness an overdose. In a prior statewide purchase trial, we documented high levels of naloxone access at Massachusetts pharmacies under a statewide NSO. In this study, we characterize barriers to pharmacy-based naloxone uptake among potential opioid overdose "bystanders" (friends or family of people who use opioids) that may be amenable to intervention.

METHODS

Eligible bystanders were Massachusetts residents ≥ 18 years of age, did not use illicit opioids in the past 30 days, and knew someone who currently uses illicit opioids. We used a sequential mixed methods approach, in which a series of semi-structured qualitative interviews (N = 22) were conducted April-July 2018, to inform the development of a subsequent quantitative survey (N = 260), conducted February-July 2020.

RESULTS

Most survey participants (77%) reported ever obtaining naloxone but few (21%) attempted to purchase it at a pharmacy. Qualitative participants revealed that barriers to utilizing the NSO included low perceived risk of overdose, which was rooted in misconceptions regarding the risks of prescription opioid misuse, denial about their loved one's drug use, and drug use stereotypes; inaccurate beliefs about the impact of naloxone on riskier opioid use; and concerns regarding anticipated stigma and confidentiality. Many participants had engaged in mutual support groups, which served as a source of free naloxone for half (50%) of those who had ever obtained naloxone.

CONCLUSIONS

Despite high levels of pharmacy naloxone access in Massachusetts, few bystanders in our study had attempted to obtain naloxone under the NSO. Low perceived risk of overdose, misinformation, stigma, and confidentiality were important barriers to pharmacy naloxone uptake, all of which are amenable to intervention. Support groups provided a setting for addressing stigma and misinformation and provided a discreet and comfortable setting for naloxone access. Where these groups do not exist and for bystanders who do not participate in such groups, pharmacies are well-positioned to fill gaps in naloxone availability.
