A community pharmacy intervention for opioid medication misuse: A pilot randomized clinical trial

Revisiting the opioid and naloxone education (ONE) program: Program evaluation using the RE-AIM model four years later

OBJECTIVE

The Opioid and Naloxone Education (ONE) Program focuses on community pharmacy-based patient screening and interventions to improve population health with regard to opioid use. The purpose of this paper is to reevaluate the ONE Program performance using the RE-AIM model, in comparison to the review performed in 2019.

METHODS

The program performance of the ONE Program was evaluated from January 1, 2021 to December 31, 2022 was evaluated using the five domains of the RE-AIM model. Reach was defined as the proportion of patients receiving opioid prescriptions who completed the screening. Efficacy was defined as the proportion of individuals identified as at risk who received a pharmacist intervention. Adoption was defined as the proportion of community pharmacies who enrolled in the ONE Program. Implementation was defined as the proportion of pharmacies that enrolled that provided at least five patient screenings. Maintenance was defined as the proportion of pharmacies that completed at least one screening three months. These results were compared against evaluation of the program from October 12, 2018 to June 1, 2019.

RESULTS

Approximately 7.28 % of patients receiving opioid prescriptions were screened for risk of opioid misuse and accidental overdose (Reach). Of the patients screened, 97.4 % of patients at risk for opioid misuse or accidental overdose received a pharmacist-led intervention (Efficacy). Additionally, 49.6 % of the pharmacist that enrolled in the ONE Program completed at least five screenings (79 %) and of those, 86.4 % maintained the program three months later.

CONCLUSIONS

In years four and five of implementation, the ONE Program demonstrated improvement in four of the five domains of the RE-AIM model compared to years one and two. However, Reach declined over time. This reevaluation has demonstrated the importance of longitudinal program assessment, and the possibility of improved program performance over time.

Patient and pharmacist perspectives on opioid misuse screening and brief interventions in community pharmacies

BACKGROUND

Pharmacy-based screening and brief interventions (SBI) offer opportunities to identify opioid misuse and opioid safety risks and provide brief interventions that do not overly burden pharmacists. Currently, such interventions are being developed without patient input and in-depth contextual data and insufficient translation into practice. The purpose of this study is to qualitatively explore and compare patient and pharmacist perceptions and needs regarding a pharmacy-based opioid misuse SBI and to identify relevant SBI features and future implementation strategies.

METHODS

Using the Consolidated Framework for Implementation Research, we conducted semi-structured interviews with 8 patients and 11 pharmacists, to explore needs and barriers to participating in a pharmacy-based SBI. We recruited a purposive sample of English-speaking patients prescribed opioids for chronic or acute pain and pharmacists practicing in varied pharmacies (small independent, large-chain, specialty retail) settings. We used an inductive content analysis approach to analyze patient interview data. Then through a template analysis approach involving comparison of pharmacist and patient themes, we developed strategies for SBI implementation.

RESULTS

Most patient participants were white, older, described living in suburban areas, and were long-term opioid users. We identified template themes related to individual, interpersonal, intervention, and implementation factors and inferred applications for SBI design or potential SBI implementation strategies. We found that patients needed education on opioid safety and general opioid use, regardless of opioid use behaviors. Pharmacists described needing patient-centered training, protocols, and scripts to provide SBI. A short-self-reported screening and brief interventions including counseling, naloxone, and involving prescribers were discussed by both groups.

CONCLUSIONS

Through this implementation-focused qualitative study, we identified patient needs such as opioid safety education delivered in a private and convenient format and pharmacist needs including training, workflow integration, protocols, and a time-efficient intervention for effective pharmacy-based SBI. Alternate formats of SBI using digital health technologies may be needed for effective implementation. Our findings can be used to develop patient-centered pharmacy-based SBI that can be implemented within actual pharmacy practice.

A scoping literature review of pharmacy-based opioid misuse screening and brief interventions

BACKGROUND

Although prescription opioid dispensing rates have continued to decrease, overdose deaths involving prescription opioids have increased during the COVID-19 pandemic. Screening and brief interventions (SBI) are an effective prevention strategy to identify and address opioid misuse and safety risks. Emerging literature on pharmacy-based SBI needs to be systematically appraised to develop robust interventions.

OBJECTIVE

Our objective was to conduct a scoping review of the literature regarding pharmacy-based opioid misuse SBI to identify relevant literature that explore the topic, evaluate the patient-centeredness of included studies, and explore the use of dissemination and implementation science in the literature.

METHODS

The review was conducted according to Preferred Reporting of Systematic Reviews and Meta-analyses -Scoping reviews (PRISMA-Sc) guidelines. We searched PubMed, CINHAL, PsychInfo, and Scopus for studies regarding pharmacy-based SBI, published in the last 20 years. We also conducted a separate grey literature search. Two of three total reviewers screened each abstract individually and identified eligible full-texts for inclusion. We critically appraised quality of included studies and qualitatively synthesized the relevant information.

RESULTS

The search resulted in 21 studies (categorized as intervention, descriptive, and observational research) and 3 grey literature reports. Of the recently published 21 studies, 11 were observational research, with six interventions in the pilot stages. Screening tools varied but naloxone was the brief intervention in 15 of the 24 results. Only eight studies had high validity, reliability, and applicability and only five were patient-centered. Implementation science principles were addressed in eight studies (mainly interventions). Overall, the findings suggest high potential for evidence-based SBI to be successful.

CONCLUSIONS

Overall, the review suggested a strong lack of a patient-centered and implementation science-focused approach to designing pharmacy-based opioid misuse SBI. Findings suggest that a patient-centered, implementation focused approach is needed for effective and sustained pharmacy-based opioid misuse SBI.

Global Advancement in Pharmacy Services for Mental Health: A Review for Evidence-Based Practices

The symptoms of psychiatric infirmities have variability, and selected drug regimens for mental illness are comparatively complex and individualized; therefore, pharmacy services vary with respect to patients, diseases, healthcare settings, community structures, and countries. Clinical pharmacy services for mental health (MH) are continuously being upgraded. A structured search of the literature was performed in the Cochrane, PubMed (Medline), PsycINFO, Google scholar, Scopus, Science Direct, and Springer Links databases. The title and abstract of each retrieved article were evaluated for relevance. To remove uncertainty and ambiguity, the full-text articles were retrieved and examined for relevance. The articles were further assessed on the basis of inclusion and exclusion criteria. Narrative synthesis was performed, creating new categories and relevant subcategories and further subsections. The articles and the results were assessed for quality and bias. Pharmacists have a range of expertise in psychiatric care. The services can be classified as conventional, extended, and advanced pharmacy services. Conventional services include the quality use of medicines in healthcare settings and medication support services in communities that ensure medication adherence. Pharmacists perform extended roles in collaborative medication therapy management, multidisciplinary community mental health teams, collaborative care, patient education, home medication review, hospital-to-home transit, and screening services. In the USA, the role of pharmacists was advanced by prescribing as collaborative and interim prescribers. Australia launched an accredited program for psychiatric first-aid pharmacists. Pharmacists can provide mental care to rural populations using health technology. The role of pharmacists in MH is appreciated either independently or as a team member. Patients and healthcare providers rank the services of pharmacists in MH highly. Still, there is a margin for improvement in the training of pharmacists. Pharmacists cannot provide sufficient time to their patients. Public awareness about the role of pharmacists in MH needs more attention. Moreover, the training of psychiatric pharmacists should be standardized around the world.

The Role of the Pharmacist in Combating the Opioid Crisis: An Update

Introduction

The opioid overdose crisis has claimed hundreds of thousands of lives in the United States in the last decade, with overdose numbers continuing to climb. At the same time, the role of the pharmacist in combating the opioid crisis continues to evolve.

Methods

A literature search was conducted in Ovid MEDLINE that incorporated both MeSH terms and keywords to describe two concepts: the opioid epidemic and pharmacists/pharmacies. The search was limited to articles published after 2010 through the end of 2021 and returned 196 articles that were analyzed thematically.

Results

Thematic analysis revealed the following themes: prevention, interventions, public health role of the pharmacist, pharmacists in multiple roles, barriers, pharmacist and healthcare provider attitudes, educational initiatives for pharmacists and student pharmacists, and future research.

Discussion

While a great deal of progress has been made in the role of the pharmacist in supporting individuals with opioid use disorder (OUD) in the last two decades, pharmacists must seek to invest time and resources into practices with a strong evidence base to better mitigate the growing, devastating impact of the opioid crisis. Pharmacists must be willing to embrace new and non-traditional roles in patient care, service and research, and seek to advance evidence-based knowledge and practice.

Conclusion

Pharmacy practice has expanded greatly in the past decade with pharmacists taking on new and creative approaches to addressing the opioid crisis. Collaborative and interdisciplinary approaches to addressing the root causes of opioid misuse and opioid overdose are still desperately needed. These include attention to the critical roles of social determinants of health, stigma elimination, legislative advocacy for patients with OUD, and focused education for providers, pharmacists, and the community. Recognition and support of the value of collaboration to both improve public health and individual patient care, continued investments in pharmacy practice advancement in OUD treatment and harm reduction, and the creation of workflows and prescribing algorithms to assist in dosing medications to prevent withdrawal symptoms and achieve improved pain control are desperately needed.

Attitude of community pharmacists toward patients with a substance-related disorder (heroin, alcohol and tobacco), estimation of harmfulness and knowledge of these substances, and continuing education: A pilot cross-sectional study

OBJECTIVES

To investigate attitude of community pharmacists toward patients with a substance-related disorder (heroin, alcohol and tobacco).

MATERIAL AND METHODS

The attitudes were assessed thanks to the Attitude to Mental Illness Questionnaire (AMIQ) for heroin, alcohol and tobacco-related disorders in three independent groups of pharmacists. Estimation of substance-related harmfulness, knowledge of substance-related disorders and activities/needs for continuing education on substance-related disorders were also recorded.

RESULTS

Thirty-five pharmacists were included (heroin: 11, alcohol: 10 and tobacco: 14). AMIQ scores for heroin-related disorder were negative and lower than for alcohol (P<0.01) and tobacco (P<0.001). AMIQ scores for alcohol-related disorder were lower than for tobacco (P<0.05). The estimation of heroin-related harmfulness was higher than for alcohol and tobacco (P<0.001). The estimations of knowledge of substance-related disorders were lower for opioid and alcohol than for tobacco (P<0.001). AMIQ scores and the needs for continuing education on each associated addiction showed a positive relation (P<0.01).

CONCLUSION

Pharmacists had a negative attitude toward heroin and alcohol-related disorders. A positive attitude toward patients with a substance-related disorder was associated with a need for continuing education. Efforts should be made to change attitudes and to promote continuing education on heroin and alcohol-related disorders.

Addressing opioid medication misuse at point of service in community pharmacy: A study protocol for an interdisciplinary behavioral health trial

BACKGROUND

>1 in 3 of the 9 million individuals engaged in opioid medication misuse obtain legitimate opioid prescriptions and fill these in community pharmacies, which are subsequently misused. This study is testing the efficacy of a pharmacist-led intervention-Brief Intervention-Medication Therapy Management (BI-MTM)-compared to standard medication counseling (SMC) to address opioid medication misuse.

METHODS

Design. This study is a single-blinded 2-group parallel randomized trial within 13 community pharmacies that will enroll 350 individuals. Participant Recruitment. Pharmacy staff approach patients and ask about interest in completing a brief confidential screening tool, which includes opioid medication misuse assessment. Interested patients who report misuse are asked to provide informed consent. Enrolled patients are assessed for behavioral and physical health at enrollment, 2-months post-enrollment, and 6-months post-enrollment.

INTERVENTIONS

Following baseline assessment, participants are randomized (1:1 ratio) to: SMC, a medication information/counseling intervention or BI-MTM, an intervention comprised by 4 evidence-based components: medication therapy management, brief intervention, naloxone dispensing, and patient navigation.

ANALYSES

Primary analyses involve estimating 3-level generalized linear mixed models to relate repeated assessments across time of opioid medication misuse (i.e., the Prescription Opioid Misuse Index) to the intervention.

CONCLUSION

Study results will provide the first critical step towards integrating a highly accessible, low-cost approach to managing risks related to opioid use. Community pharmacies provide an incredibly important setting in which patients can receive high quality care to support health behavior change. Successfully completing this project sets the stage for a large-scale effectiveness study. (NCT#: NCT05141266).

Brief intervention medication therapy management: Establishment of an opioid misuse intervention model delivered in a community pharmacy

PURPOSE

Medication expertise and close patient contact position community pharmacists to make significant contributions to combatting the opioid epidemic. This position facilitated the development and initial implementation of the Brief Intervention Medication Therapy Management (BIMTM) model to detect and address patient opioid misuse. BIMTM is an intervention consisting of 9 sessions. One medication management session is delivered by a pharmacist in a community pharmacy setting, and the remaining sessions are delivered telephonically by a patient navigator to follow up with goals established with the pharmacist and address concomitant health concerns that increase risk for misuse.

METHODS

We employed the Consolidated Framework for Implementation Research (CFIR) to summarize and present key findings from 4 distinct studies. CFIR domains addressed were (1) intervention characteristics, (2) outer setting, (3) inner setting, (4) process, and (5) characteristics of individuals. The study results show sequential development of evidence for BIMTM.

RESULTS

A multistate cross-sectional pharmacist survey (n = 739) demonstrated limited pharmacist training and/or resources to address misuse, suggesting the need for external intervention development. Our multistakeholder intervention planning project showed limitations of current evidence-based models of care and of intervention implementation, which resulted in construction of the BIMTM. A multisite cross-sectional screening survey of patients (n = 333) established an electronic misuse screening protocol within 4 community pharmacies and identified opioid misuse in 15% of screened patients; among those patients, 98% had concomitant health conditions that contribute to the risk of opioid misuse. Presentation of study results to pharmacy leaders produced commitment for intervention implementation and a partnership to develop a grant proposal supporting this action. Our small-scale randomized trial evinced success in recruitment and retention and BIMTM patient benefit. The small-scale randomized trial likewise showed high levels of satisfaction with BIMTM.

CONCLUSION

The establishment of BIMTM supports community pharmacist identification and intervention with patients engaged in misuse. Continued use of this research-based strategy may further empower pharmacists to address the opioid epidemic.

Abuse-Deterrent Opioid Formulations and the Opioid Crisis: A Pharmacist's Perspective

BACKGROUND

For over 20 years, the United States has suffered the detrimental effects of an opioid epidemic. Extended-release opioid products are particularly prone to abuse due to the high amount of opioid present. By bypassing the controlled-release mechanisms and nonoral administration, individuals experience intense and dangerous "highs." Abuse-deterrent opioid formulations have been recommended as a potential solution to the crisis, but widespread utilization has been stunted and their role in therapy remains unclear owing to limited real-world efficacy data and affordability issues. This review discusses abuse-deterrent opioid formulations, the mechanisms and data underlying available products, and a pharmacist's perspective of their role in the opioid crisis.

METHODS

The authors reviewed PubMed, MEDLINE, and Google Scholar electronic databases for premarketing and postmarketing studies on OxyContin, Xtampza ER, and Hysingla ER.

RESULTS

Studies showed lower rates of abuse (19% reduction), opioid use disorder (27%), overdose (34%), and fatalities (85%) with the reformulated OxyContin when compared with the original product and comparator opioids. However, these studies revealed the potential for bypassing abuse-deterrent mechanisms and diverting abuse to other drugs. Postmarketing studies are unavailable for Xtampza ER or Hysingla ER, although premarketing studies suggested that some controlled-release properties persist when the product is manipulated, indicating that abuse may be more difficult and less rewarding.

CONCLUSIONS

Abuse-deterrent opioid products may lead to reductions in abuse, overdose, and overdose fatalities. However, cost, loopholes in deterrence mechanism, and possible diversion to other substances hinder their role in the opioid crisis. Multiple approaches must be used to improve opioid safety, and further postmarketing and real-world analyses should be performed on available opioid formulations to assess their impact on abuse-related adverse events.

Pharmacist Views Regarding the Prescription Opioid Epidemic

Community pharmacists have significant opportunity to contribute to prevention and treatment of opioid use disorders, but barriers to implementation still exist. Understanding their viewpoints is critical to designing future interventions. To qualitatively explore experiences and beliefs of community pharmacists regarding the misuse of prescription opioids in the United States. The study was part of a larger project that utilized a survey questionnaire to evaluate the relationships between knowledge, attitudes, and practices of community pharmacists in substance use disorders. The survey included an open-ended item on pharmacist views regarding the prescription opioid epidemic. The responses were used for inductive content analysis. Axial coding of themes was conducted to analyze underlying relationships: associations, consequences, intervening relationships, and action strategies regarding a central phenomenon. A model describing pharmacist experiences in the opioid epidemic was conceptualized. The open-ended question resulted in 50 (37.3%) usable responses. Final abstraction resulted in six themes including (1) overprescribing opioids: inappropriate prescribing as a contributor to the epidemic, (2) policy and practice recommendations: potential action strategies against the epidemic, (3) poor prescriber-pharmacist relationship: barrier to addressing the epidemic, (4) negative attitudes: intervening condition affecting roles of the pharmacist, (5) personal experience: facilitator to improve pharmacist roles and (6) decreased access to opioids: consequence of strict prescribing laws. The study identified themes that described pharmacist views, attitudes, barriers, and experiences related to their perceived role in prevention and treatment of opioid use disorders. Future research should consider the implications of the barriers and facilitators identified.

Role of pharmacists in optimising opioid therapy for chronic non-malignant pain; A systematic review

BACKGROUND

Opioid optimisation is a global issue in Chronic Non-malignant Pain (CNMP) management.

OBJECTIVE

This systematic review aims to assess the effectiveness of interventions delivered by pharmacists in outpatient clinical settings, community pharmacies and primary care services in optimising opioid therapy for people with CNMP and to explore stakeholders' opinions about role of pharmacists in optimising opioid therapy.

METHODS

We conducted searches in PubMed, CINAHL, Psych Info, EMBASE, ISI Web of Science and Conference Proceedings and International Pharmaceutical Abstracts. All studies where pharmacists in outpatient clinical settings, community pharmacies and patient care services helped in optimisation of opioids in the treatment of CNMP as individuals or part of a team were included. Authors followed the 27-item PRISMA guidelines and the review was registered in PROSPERO. All authors were involved in screening and selection of studies and included studies between January 1990-June 2020. Studies not published in English language and participants with cancer pain were excluded. All the included studies were descriptively synthesized.

RESULTS

Fourteen studies were included in the final data synthesis of this review and the total number of participants in all studies was 1175. Interventions by pharmacists were successful in decreasing opioid dose in 4 studies and improved patient opioid safety in 5 studies. Stakeholders considered that the role of pharmacists in optimisation of opioid therapy for people with CNMP can be promising and should be further developed.

CONCLUSION

This systematic review gives an overview of pharmacist intervention feasibility, stakeholders' opinions and possible benefits on opioid optimisation in people with CNMP in outpatient clinical settings, community pharmacies and primary care settings. However, further research is warranted, which can guide the development of new policies and guidelines for the utilisation of pharmacists to promote opioid safety in people using prescription opioids for CNMP management.

Implementation of hepatitis C screening within a pharmacist-managed medication-assisted therapy opioid use disorder protocol program

OBJECTIVES

(1) To describe an innovative medication-assisted therapy (MAT) opioid use disorder (OUD) protocol in an independent community pharmacy, (2) to assess patient retention of the protocol, and (3) to describe the implementation of pharmacist-initiated hepatitis C virus (HCV) screenings of patients enrolled in the protocol.

SETTING

Independent pharmacy affiliated with a detox and rehabilitation center in Louisville, KY.

PRACTICE DESCRIPTION

A postgraduate year 1 (PGY-1) pharmacy resident-led OUD and HCV screening protocol.

PRACTICE INNOVATION

Under the Kentucky MAT OUD protocol, pharmacists at St. Matthews Community Pharmacy recognized the lack of HCV screening as a protocol requirement. To provide comprehensive care, the pharmacists added an HCV screening assessment for all patients enrolled in the pharmacy MAT OUD program.

EVALUATION

The pharmacy was the first in Kentucky to implement the MAT OUD protocol after state board approval in January 2018. Patient retention rates of the MAT OUD protocol were evaluated during the 2018-2019 PGY-1 pharmacy residency program. HCV screening was implemented and assessed during this time.

RESULTS

The service was implemented by the pharmacy practice resident with 77 patients enrolled in the MAT OUD program and 36 consenting to the HCV screening assessments. More than half (52%) of the study participants remained in the MAT OUD program for the recommended duration of 6 months or more. All study participants (n = 36) had recent HCV screenings.

CONCLUSION

This practice innovation, led through the PGY-1 pharmacy residency program, allowed patients to enroll in a MAT OUD program in the privacy of their community pharmacy. The patient retention rate was similar to those found in physician-provided OUD programs. HCV positive screenings were found in individuals with no previous history of intravenous drug use. This provides reasoning to consider adding HCV screenings as a requirement to OUD protocols.

Advancing preventive interventions for pregnant women who are opioid using via the integration of addiction and mental health research

Purpose of Review

This review examines how research focused on treatment for opioid use in perinatal populations and preventive interventions for postpartum psychopathology have remained separate, despite significant overlap.

Recent Findings

Guidelines for best practice in caring for pregnant women with opioid use disorder suggest the use of medication-assisted treatment with additional comprehensive care, including behavioral and mental health interventions. However, intervention research often mutually excludes these two populations, with studies of behavioral interventions for opioid use excluding women with psychopathology and research on preventive interventions for postpartum psychopathology excluding women who are substance using.

Summary

There is a limited evidence-base to inform the selection of appropriate preventive interventions for pregnant women with opioid use disorder that can address opioid use and/or treatment adherence and concurrent mental health risks. We argue it is critical to integrate research on pregnant women who are opioid using and preventive perinatal mental health interventions to catalyze pivotal change in how we address the opioid epidemic within this growing population.

Pharmacy: Addressing substance use in the 21st century

Across all care environments, pharmacists play an essential role in the care of people who use and misuse psychoactive substances, including those diagnosed with substance use disorders. To optimize, sustain, and expand these independent and collaborative roles, the Association for Multidisciplinary Education and Research in Substance Use and Addiction (AMERSA) has developed core competencies for pharmacists to address substance use in the 21st century. Key concepts, skills, and attitudes are outlined, with links to entrustable professional activities to assist with integration into a variety of ideally interdisciplinary curricular activities.

A community pharmacy-led intervention for opioid medication misuse: A small-scale randomized clinical trial

BACKGROUND

Stemming the opioid epidemic requires testing novel interventions. Toward this goal, feasibility and acceptability of a Brief Motivational Intervention-Medication Therapy Management (BMI-MTM) intervention was examined along with its impact on medication misuse and concomitant health conditions.

METHODS

We conducted a two-group randomized trial in 2 community pharmacies. We screened patients for prescription opioid misuse at point-of-service using the Prescription Opioid Misuse Index. Participants were assigned to standard medication counseling (SMC) or SMC + BMI-MTM (referred to as BMI-MTM herein). BMI-MTM consists of a pharmacist-led medication counseling/brief motivational session and 8-weekly patient navigation sessions. Assessments were at baseline, 2-, and 3-months. Primary outcomes included feasibility, acceptability, and mitigation of opioid medication misuse. Secondary outcomes included pain and depression. Outcomes were analyzed with descriptive and multivariable statistics (intent-to-treat [ITT] and adjusted for number of sessions completed [NUMSESS]).

RESULTS

Thirty-two participants provided informed consent (74.4% consent rate; SMC n = 17, BMI-MTM n = 15; 3-month assessment retention ≥93%). Feasibility was demonstrated by all BMI-MTM recipients completing the pharmacist session and an average of 7 navigation sessions. BMI-MTM recipients indicated ≥4.2 (5 maximum) level of satisfaction with the pharmacist-led session, and 92.4% were satisfied with navigation sessions. Compared to SMC at 3-months, BMI-MTM recipients reported greater improvements in misuse (ITT: Adjusted Odds Ratio [AOR] = 0.13; 95% CI = 0.05, 0.35, p < 0.001.

NUMSESS

AOR = 0.05; 95% CI = 0.01, 0.25; p < 0.001), pain (ITT: В = 8.8, 95% CI=-0.95, 18.5, p = 0.08; NUMSESS: В = 14.0, 95% CI = 3.28, 24.8, p = 0.01), and depression (ITT: B= -0.44; 95% CI=-0.65, -0.22; p < 0.001.

NUMSESS

B= -0.64; 95% CI=-0.82, -0.46; p < 0.001).

CONCLUSIONS

BMI-MTM is a feasible misuse intervention associated with superior satisfaction and outcomes than SMC. Future research should test BMI-MTM in a large-scale, fully-powered trial.

Psychiatric comorbidity and co-occurring opioid misuse: Depression mediates the relationship between post-traumatic stress disorder and opioid misuse in community pharmacy settings

AbstractsBackground: Individuals who misuse opioids frequently have comorbid psychiatric issues, including post-traumatic stress disorder (PTSD) and depression. However, little is known about the mechanisms by which these disorders are associated with opioid misuse and specifically in community pharmacy settings. The current study examined whether depression mediated the relationship between PTSD and opioid misuse in patients filling opioid prescriptions. Methods: We administered a health survey in four community pharmacies among patients filling opioid medications in southwestern Pennsylvania. Univariate statistics were used to assess relationships among demographic and clinical characteristics of PTSD, depression, and opioid misuse behaviors. We then examined whether depression mediated the relationship between PTSD and opioid misuse using ordinary least squares path analysis with bootstrapping. Results: A total of 333 participants completed the health survey. Opioid misuse was reported among 15.9% of all participants, 33.3% among those with a positive PTSD screen, and 29.3% of those who screened positive for depression. Depression significantly mediated the relationship between PTSD and opioid misuse. Specifically, there was a statistically significant indirect effect (ab) of PTSD on opioid misuse through a pathway mediated by depression (ab = .06, SE_ab = .02, 95% CI = .02-.10). The direct effect (c') of PTSD on opioid misuse was also significant (c' = .12, SE_c' = .05, P = .01, 95% CI = .03-.22), suggesting partial mediation. Conclusions: Results suggest an indirect pathway by which clinical intervention may help ameliorate outcomes in patients with PTSD. Further, there is an increased need for screening, assessment, and intervention protocols for this patient population in which community pharmacy is a novel setting to expand future efforts within the patient population.

Leveraging the role of community pharmacists in the prevention, surveillance, and treatment of opioid use disorders

The global rise in opioid-related harms has impacted the United States severely. Current efforts to manage the opioid crisis have prompted a re-evaluation of many of the existing roles in the healthcare system, in order to maximize their individual effects on reducing opioid-associated morbidity and preventing overdose deaths. As one of the most accessible healthcare professionals in the US, pharmacists are well-positioned to participate in such activities. Historically, US pharmacists have had a limited role in the surveillance and treatment of substance use disorders. This narrative review explores the literature describing novel programs designed to capitalize on the role of the community pharmacist in helping to reduce opioid-related harms, as well as evaluations of existing practices already in place in the US and elsewhere around the world. Specific approaches examined include strategies to facilitate pharmacist monitoring for problematic opioid use, to increase pharmacy-based harm reduction efforts (including naloxone distribution and needle exchange programs), and to involve community pharmacists in the dispensation of opioid agonist therapy (OAT). Each of these activities present a potential means to further engage pharmacists in the identification and treatment of opioid use disorders (OUDs). Through a careful examination of these approaches, we hope that new strategies can be adopted to leverage the unique role of the community pharmacist to help reduce opioid-related harms in the US.
