Special Issue Information

Dear Colleagues,

The opioid crisis is escalating at an alarming rate, constituting a pressing public health emergency. The COVID-19 pandemic has exacerbated the situation, significantly increasing opioid-related harms and fatalities. While illicit opioids are a key driver of this crisis, a troubling surge in opioid prescriptions also warrants attention as a contributing factor. Pain remains one of the most prevalent reasons individuals seek healthcare in North America and beyond, and prescription opioids are often the go-to solution. However, the long-term use of these medications can lead to physical dependence and tolerance, compelling patients to increase their doses in pursuit of relief. This dangerous cycle significantly amplifies the risk of addiction. In many instances, those affected by opioid use disorder (OUD) resort to various methods to obtain prescription opioids, including acquiring prescriptions from multiple doctors without disclosure (a practice known as double doctoring), committing fraud, stealing, tapping into street drug markets, or making online purchases. It is imperative that we confront the opioid crisis head-on, as effective strategies not only stand to improve patient health outcomes but also carry profound economic implications. The escalating costs associated with opioid misuse are unsustainable, and as the crisis deepens, these expenses will likely skyrocket. By investing in comprehensive, alternative approaches to managing opioid use, we can not only protect the health of our communities but also secure significant cost savings for our healthcare system. The time for decisive action is now.

The opioid epidemic continues to be a major public health crisis in the United States, and nalmefene has recently emerged as an alternative opioid overdose reversal agent. However, little is known about pharmacists’ awareness and beliefs regarding nalmefene use and distribution. Therefore, the purpose of this study was to assess Alabama pharmacists’ knowledge, perceptions, and behavioral intentions related to nalmefene. This study used a cross-sectional survey design. Practicing pharmacists in the state of Alabama were eligible to participate, and were recruited through the Alabama Board of Pharmacy email listserv. An anonymous online survey was distributed via email, and respondents were eligible to enter a lottery for one of five $100 electronic gift cards. The survey instrument was developed by the investigators, adapted from prior overdose reversal literature and informed by the Theory of Planned Behavior. Primary outcome measures included: knowledge of nalmefene (12 items); perceived barriers regarding nalmefene stocking and recommendations (19 items); and Theory of Planned Behavior concepts including attitudes (15 items), subjective norms (perceived social support) (six items), perceived behavioral control (confidence in ability to stock or recommend nalmefene) (11 items), and behavioral intentions surrounding nalmefene stocking and recommendations (13 items). Outcomes were measured via multiple-choice (objective knowledge) and Likert-type scale (1 = strongly disagree, 5 = strongly agree) questions. Differences in mean scale scores across pharmacy setting (pharmacists employed in inpatient versus outpatient settings), community pharmacy type (chain vs. independent), and geographic location (rural vs. urban) were analyzed using two-sided Mann–Whitney U tests for non-parametric data or t-tests for parametric data, as appropriate. Multiple linear regression analyses examined associations between TPB constructs and pharmacists’ intentions to stock or recommend nalmefene over the next six months. All data were analyzed using SPSS statistical software version 29 with an alpha of 0.05. There were 119 pharmacist respondents (n = 25 inpatient, n = 94 outpatient). The majority were female (68.1%), White (94.1%), and worked in community settings (35.3% independent, 10.9% corporate, 10.1% big-box, 5.0% grocery). Median age was 42 years (IQR: 36–51). Awareness of nalmefene was low: only 39.5% had heard of it and 5.9% had seen it in practice. Inpatient versus outpatient pharmacists reported higher subjective norms external to the workplace (median [IQR]: 3.00 [2.33, 3.58] vs. 2.33 [1.67, 3.00]; p = 0.004) as well as subjective knowledge (mean [SD]: 2.96 [0.94] vs. 2.55 [0.74]; p = 0.023), while outpatient versus inpatient pharmacists reported higher perceived barriers related to fiscal/logistical concerns (mean [SD]: 3.45 [0.59] vs. 3.07 [0.66]; p = 0.009). Among community pharmacists, stocking and procurement confidence was higher among independent versus chain pharmacists (3.75 [3.00–4.17] vs. 3.17 [2.67–3.92]; p = 0.026). Furthermore, external workplace norms among urban pharmacists were higher than among rural pharmacists (2.50 [2.00–3.00] vs. 2.33 [1.67, 2.67]; p = 0.027), while stocking and procurement confidence was higher among rural than urban pharmacists (3.83 [2.83–4.50] vs. 3.17 [2.67–4.00]; p = 0.034). In adjusted reduced regression models, perceived behavioral control regarding nalmefene stocking and procurement (B = 0.189, 95% CI: 0.049, 0.329; p = 0.009), subjective norms external to the workplace (B = 0.232, 95% CI: 0.047, 0.418; p = 0.015), and interprofessional recommendation attitudes (B = 0.237, 95% CI: 0.037, 0.437; p = 0.021) positively predicted nalmefene implementation intentions. These findings suggest practice-setting differences that could be further explored for optimal implementation of nalmefene distribution and access, and highlight the need for targeted education, interprofessional collaboration, procurement guidance, and workflow tools to improve pharmacist preparedness for nalmefene services.

During the COVID-19 pandemic, Health Canada temporarily exempted pharmacists from specific restrictions under the Controlled Drugs and Substances Act (CDSA), allowing them to prescribe opioids. However, it is not yet established whether opioid dispensing patterns differ between urban and rural pharmacists. This study aims to assess the impact of the CDSA subsection 56(1) temporary exemption on opioid prescribing practices among urban and rural pharmacists between 1 February 2018 and 30 April 2022. Descriptive statistics and visualizations assessed differences in opioid prescribing between urban and rural pharmacists under the CDSA exemption. Initial analyses employed linear regression to examine changes, followed by evaluation of temporal dependence using autocorrelation and residual analysis. When appropriate, a suitable time series model was subsequently applied. Following the CDSA exemption, the mean weekly proportion of opioid claims prescribed by urban pharmacists increased from 0.0% to 1.03%. In contrast, rural pharmacists’ prescriptions rose from 0.0% to 0.35%. The estimated mean level change was 0.667% for urban pharmacists (95% CI: 0.520–0.838%, p < 0.0001) and 0.201% for rural pharmacists (95% CI: 0.140–0.291%, p < 0.0001). The study identified distinct differences in opioid prescribing practices between urban and rural pharmacists in Nova Scotia. Furthermore, opioid prescriptions increased steadily across all patient groups, indicating evolving patterns of opioid use within the province. Full article
