Economic burden of opioid crisis and the role of pharmacist-led interventions

The effect of out-of-pocket costs on medications for opioid use disorder and overdose: A scoping review

BACKGROUND

The opioid epidemic is a major public health crisis in Canada and elsewhere. The increase in opioid prescriptions is a major contributor to this crisis. Medications for opioid use disorder (OUD) and overdose are effective and lifesaving treatments. Often, patients do not have adequate insurance coverage (or uninsured) for medications for OUD and have to pay out of pocket (OOP). OOP costs (OOPCs) result in financial burdens among patients, limiting their access to medications for OUD, and overdose.

OBJECTIVES

To identify the evidence on (1) the OOPCs of medications for OUD and overdose, and (2) the effect of insurance coverage (or being uninsured) and corresponding OOPCs on medications for OUD initiation, retention, and discontinuation.

METHODS

This scoping review was conducted in accordance with methodological guidance from the Joanna Briggs Institute. The literature search aimed to identify peer-reviewed publications in English in MEDLINE, Embase, and CINAHL, which were searched from inception to March 22, 2024. Two reviewers independently completed title, abstract, and full-text screening against inclusion criteria. Data extracted were used to describe the body of literature using descriptive and qualitative approaches.

RESULTS

Out of the 2003 search results, a total of ten studies met the inclusion criteria and were included in the review. Uninsured patients have paid higher OOPCs compared to private or publicly insured patients. Among privately insured patients with OUD, greater OOPC may result in poor retention of buprenorphine. The risk of discontinuation was higher with the buprenorphine/naloxone tablet compared with the sublingual buprenorphine/naloxone film. Generic substitution or providing coverage for these medications being dispensed from community pharmacies can potentially minimize the burden of OOPCs and improve access.

CONCLUSION

The literature highlights beneficiaries of private/commercial health plans experience a substantial burden of OOPCs, creating barriers to treatment initiation, retention, and adherence to medications for OUD.

A Guide to Expanding the Use of Buprenorphine Beyond Standard Initiations for Opioid Use Disorder

Buprenorphine has become an important medication in the context of the ongoing opioid epidemic. However, complex pharmacologic properties and varying government regulations create barriers to its use. This narrative review is intended to facilitate buprenorphine use-including non-traditional initiation methods-by providers ranging from primary care providers to addiction specialists. This article briefly discusses the opioid epidemic and the diagnosis and treatment of opioid use disorder (OUD). We then describe the basic and complex pharmacologic properties of buprenorphine, linking these properties to their clinical implications. We guide readers through the process of initiating buprenorphine in patients using full agonist opioids. As there is no single recommended approach for buprenorphine initiation, we discuss the details, advantages, and disadvantages of the standard, low-dose, bridging-strategy, and naloxone-facilitated initiation techniques. We consider the pharmacology of, and evidence base for, buprenorphine in the treatment of pain, in both OUD and non-OUD patients. Throughout, we address the use of buprenorphine in children and adolescent patients, and we finish with considerations related to the settings of pregnancy and breastfeeding.

Organizational Readiness to Implement Community Pharmacy-Based Opioid Counseling and Naloxone Services: A Scoping Review of Current Practice Models and Opportunities

The purpose of this study was to explore existing practice models and opportunities surrounding community pharmacist-delivered opioid counseling and naloxone (OCN) services in the U.S., with the goal of enhancing organizational readiness and improving patient access. A scoping literature review was conducted. English-language articles published in peer-reviewed journals from January 2012-July 2022 were sought via PubMed, CINAHL, IPA, and Google Scholar using permutations of terms such as "pharmacist/pharmacy", "opioid/opiate", "naloxone", "counseling", and "implement/implementation". Original articles reporting the resources/inputs (personnel; pharmacist full-time equivalents; facilities and expenses; in-house versus outsourced personnel), implementation processes (legal source of pharmacist authority; patient identification strategies; intervention procedures; workflow strategies; business operations), and programmatic outcomes (uptake and delivery; interventions made; economic impact; patient or provider satisfaction) of pharmacist-delivered OCN services in community (retail) settings were retained. Twelve articles describing ten unique studies were included. The studies primarily used quasi-experimental designs and were published from 2017 to 2021. The articles described seven broad program elements/themes: interprofessional collaboration (n = 2); patient education format including one-on-one patient education (n = 12) and group education sessions (n = 1); non-pharmacist provider education (n = 2); pharmacy staff education (n = 8); opioid misuse screening tools (n = 7); naloxone recommendation/dispensing (n = 12); and opioid therapy and pain management (n = 1). Pharmacists screened/counseled 11-2716 patients and provided 11-430 doses of naloxone. Limited implementation costs, patient/provider satisfaction, or economic impact measures were reported. This review may serve as a guide for community pharmacists in implementing OCN services in their own practices. Future studies should clarify OCN program implementation costs, patient/provider satisfaction, and the economic impact.

Addressing the Opioid Crisis—The Need for a Pain Management Intervention in Community Pharmacies in Canada: A Narrative Review

Background: The opioid crisis is a public health concern in Canada with a continued rise in deaths and presents a significant economic impact on the healthcare system. There is a need to develop and implement strategies for decreasing the risk of opioid overdoses and other opioid-related harms resulting from the use of prescription opioids. Pharmacists, as medication experts and educators, and as one of the most accessible frontline healthcare providers, are well positioned to provide effective opioid stewardship through a pain management program focused on improving pain management for patients, supporting appropriate prescribing and dispensing of opioids, and supporting safe and appropriate use of opioids to minimize potential opioid misuse, abuse, and harm. Methods: A literature search was conducted in PubMed, Embase and grey literature to determine the characteristics of an effective community pharmacy-based pain management program, including the facilitators and barriers to be considered. Discussion: An effective pain management program should be multicomponent, address other co-morbid conditions in addition to pain, and contain a continuing education component for pharmacists. Solutions to implementation barriers, including pharmacy workflow; addressing attitudes beliefs, and stigma; and pharmacy remuneration, as well as leveraging the expansion of scope from the Controlled Drugs and Substances Act exemption to facilitate implementation, should be considered. Conclusions: Future work should include the development, implementation, and evaluation of a multicomponent, evidence-based intervention strategy in Canadian community pharmacies to demonstrate the impact pharmacists can have on the management of chronic pain and as one potential solution to helping curb the opioid crisis. Future studies should measure associated costs for such a program and any resulting cost-savings to the healthcare system.

Opioid risk screening: Program evaluation from the community pharmacists' perspective

BACKGROUND

Pharmacist-implemented screening programs can be improved through continuous program evaluation. Pharmacists are in a position to determine whether interventions are realistic and efficacious when used in practice.

OBJECTIVE

The purpose of this study is to evaluate how community pharmacists perceive the use of an opioid risk screening for patients receiving opioid prescriptions and the associated implications for improved patient-centered care.

METHODS

North Dakota community pharmacists received training on the use of an opioid risk tool for all patients filling an opioid prescription to evaluate for opioid misuse and overdose risk potential. Pharmacists then implemented the screening in their community pharmacy to screen all patients prescribed an opioid. Six months after implementation, pharmacists across the state were surveyed regarding their perception of the value of screening patients for the risk of opioid misuse and overdose. The survey questions used the Joint Committee on Standards for Educational Evaluation focusing on utility, propriety, feasibility, and accuracy.

RESULTS

All pharmacists (n = 35) indicated the opioid risk screening improved patient communication and patient-centered interventions. A total of 97% of pharmacists agreed the opioid screening tool provided an objective measure in providing care to patients and improved the potential for patient safety during prescription opioid use. Although 66% of pharmacists disagreed that the screening process was time consuming, 14% of respondents agreed with this statement indicating they may require additional assistance to optimize their workflow.

CONCLUSION

The results of this study support that opioid risk screening ensures utility for opioid risk stratification, feasibility to incorporate into existing workflow, and propriety for patient safety and well-being.
