Low-dose Initiation of Buprenorphine/naloxone for the Management of Chronic Non-cancer Pain in Patients on Long-term Opioid Therapy: A Case Series.

Background: Buprenorphine may provide superior analgesia to full opioid agonist therapy and reverse the effects of opioid-induced hyperalgesia, while having a favorable safety profile and fewer adverse effects, in chronic non-cancer pain treatment. Low-dose initiation of buprenorphine is a useful strategy for patients on long-term opioid therapy because it avoids the need for moderate opioid withdrawal required for traditional buprenorphine initiations. However, there are few published reports of low-dose initiation regimens in the setting of chronic pain. Aims: The aim of the study was to describe a case series of individuals living with chronic pain who were transitioned from long-term full opioid agonist therapy onto sublingual buprenorphine/naloxone using low-dose initiation regimens. Methods: This study is a retrospective case series that included all patients who received care at an outpatient chronic pain clinic and were scheduled for low-dose initiation of buprenorphine/naloxone between March 2020 and December 2022. Data were collected through a retrospective review of electronic medical records and results were analyzed using descriptive statistics. Results: Eighteen patients underwent transitions from their baseline opioids onto buprenorphine/naloxone using a low-dose initiation regimen. Of those patients, 17 successfully completed the initiation (94.44%), 12 experienced adverse effects during the initiation (66.67%), with only one patient requiring treatment discontinuation, and all adverse effects resolved once maintenance doses of buprenorphine/naloxone were established. The mean Clinical Global Impression-Improvement score after initiation was 2 (1-5). Conclusion: Low-dose initiation is an effective approach to transition patients with chronic non-cancer pain from long-term opioid therapy to buprenorphine/naloxone without major complications or worsening pain.

Contexte: La buprénorphine peut offrir une analgésie supérieure à celle d'un traitement par agonistes opioïdes complet et inverser les effets de l'hyperalgésie induite par les opioïdes, tout en présentant un profil d'innocuité favorable et moins d'effets indésirables dans le traitement de la douleur chronique non cancéreuse. L'initiation à faible dose de la buprénorphine est une stratégie utile pour les patients sous traitement opioïde à long terme, car elle évite le besoin de sevrage des opioïdes modéré nécessaire pour les traitements traditionnels à base de buprénorphine. Cependant, il existe peu de rapports publiés sur les régimes d'initiation à faible dose dans le cadre de la douleur chronique.Objectifs: L'objectif de cette étude était de décrire une série de cas d'individus vivant avec une douleur chronique qui sont passés d'un traitement opioïde complet à long terme à un traitement par buprénorphine sublinguale/naloxone en ayant recours à des régimes d'initiation à faible dose.Méthodes: Cette étude est une série de cas rétrospective incluant tous les patients pris en charge dans une clinique externe de traitement de la douleur chronique et pour lesquels un schéma d'initiation à faible dose de buprénorphine/naloxone a été programmé entre mars 2020 et décembre 2022. Les données ont été collectées par le biais d'un examen rétrospectif des dossiers médicaux électroniques et les résultats ont été analysés à l'aide de statistiques descriptives.Résultats: Dix-huit patients ont fait la transition des opioïdes de base à la buprénorphine/naloxone en utilisant un régime d'initiation à faible dose. Parmi ces patients, 17 ont terminé l'initiation avec succès (94,44 %), 12 ont présenté des effets indésirables pendant l'initiation (66,67 %) et un seul patient a dû interrompre son traitement. Tous les effets indésirables ont disparu une fois les doses d'entretien de buprénorphine/naloxone établies. Le score d'impression clinique globale-amélioration moyen après le début du traitement était de 2 (1-5).Conclusion: L'initiation à faible dose est une approche efficace pour faire passer les patients souffrant de douleur chronique non cancéreuse d'un traitement opioïde à long terme à la buprénorphine/naloxone sans complications majeures ni aggravation de la douleur.

Between what is and what could be: a survey of pharmacists' practices, attitudes, and beliefs in the provision of mental health care.

BACKGROUND: Pharmacists can have an essential role in providing care for patients with mental illness. There are gaps in the understanding of the current extent of pharmacists' involvement in caring for patients with mental illness and their readiness to effectively provide this care. AIM: To describe the current practices, attitudes, and beliefs of pharmacists in providing care to individuals with mental illness, and to assess factors that may impact these practices. METHOD: An electronic questionnaire was emailed to pharmacists in Saskatchewan, Canada. Likert scale questions were utilized, and data were analyzed using descriptive statistics and content analysis for free-text responses. RESULTS: The response rate was 9.1% (n = 146/1596). Fewer than 20% of respondents reported they were providing the clinical services listed to most or all patients with mental illness, except for providing basic medication education (61%). Almost all agreed it is a pharmacist's role to provide all the services (61-98% for different services) and many were motivated to provide them (47-91%). The factors most frequently selected as having the greatest impact on service provision were insufficient knowledge (27%, n = 34) and competing priorities (19%, n = 24). CONCLUSION: Consistent with international trends, Saskatchewan pharmacists reported low provision of clinical services for individuals with mental illness, despite a readiness to provide these services. There is an opportunity and a need to better utilize pharmacists internationally in the provision of mental health care.

Evaluation of a pharmacist-led interprofessional chronic pain clinic in Canada.

Background: Chronic noncancer pain (CNCP) is a common condition that affects individuals at a biopsychosocial level and can significantly impair function and quality of life. Referral to an interprofessional CNCP program is recommended for most patients; however, these clinics are limited in number and capacity. Expanding access by testing new service delivery models would be of value. The purpose of this study was to measure the impact of a new pharmacist-led, interprofessional model of care developed at the University of Saskatchewan Chronic Pain Clinic. Methods: A retrospective chart audit was conducted using data that included adult patients referred for CNCP management between May 2020 and December 2021. Medication use, overall health status (using the Clinical Global Impression of Change-Improvement [CGI-I] scale) and patient readiness to change (using the Transtheoretical Model) were measured 6 months after the initial appointment. Results: The study included 138 patients. Of the 80 patients taking an opioid, 22.5% were switched to buprenorphine/naloxone and the remainder had their mean morphine-equivalent dose reduced by a mean of 41.7 mg/d. Overall patient health status was minimally improved and many patients moved into the Action stage of change. Discussion: Changes in opioid use demonstrate a clinically important shift toward safer medication regimens that are less likely to lead to toxicity and unintended overdose. CGI-I data suggest that these patients, whose health status is typically very difficult to change, did not deteriorate but slightly improved after attending the clinic. Conclusion: The unique pharmacist-led, interprofessional model of care used by the University of Saskatchewan Chronic Pain Clinic may offer a viable alternative to traditional physician-led models.

An Advanced Pharmacy Practice Experience for Community Pharmacies Based on a Clinical Intervention Targeting Patients With Inflammatory Bowel Disease.

Experiential education is a critical component of any pharmacy undergraduate curriculum. Establishing new, high-quality practice sites can be challenging. We designed a new advanced pharmacy practice experiential rotation suitable for implementation in most community pharmacy settings. The aim of this article is to describe the design of this rotation entitled the Targeted Pharmacy Intervention in Inflammatory Bowel Disease (TPI-IBD) and to determine its impact on student knowledge and confidence using a before-after survey design. The TPI-IBD utilizes a student-delivered intervention as a platform for experiential learning in community pharmacy practice. The TPI was focused on patients with IBD, and implementation was guided by a co-preceptor from the university in collaboration with onsite-preceptors at each pharmacy. The TPI-IBD rotation was delivered from 6 community pharmacies during 5 weeks in 2018. Students conducted standardized monitoring on patients with IBD and met weekly with the university preceptor for case presentations and therapeutic discussions. Electronic charts were maintained by students who were responsible for ensuring detailed documentation on each patient. Knowledge, confidence, and overall satisfaction were assessed by a survey given to students before and after the rotation. Students were highly satisfied with the learning experience and improvements in knowledge and confidence were clearly demonstrated. The TPI strategy was an effective way to expand rotation options in community pharmacy sites with minimal burden on local preceptors.

Community pharmacists' evolving role in Canadian primary health care: a vision of harmonization in a patchwork system

Canada's universal public health care system provides physician, diagnostic, and hospital services at no cost to all Canadians, accounting for approximately 70% of the 264 billion CAD spent in health expenditure yearly. Pharmacy-related services, including prescription drugs, however, are not universally publicly insured. Although this system underpins the Canadian identity, primary health care reform has long been desired by Canadians wanting better access to high quality, effective, patient-centred, and safe primary care services. A nationally coordinated approach to remodel the primary health care system was incited at the turn of the 21st century yet, twenty years later, evidence of widespread meaningful improvement remains underwhelming. As a provincial/territorial responsibility, the organization and provision of primary care remains discordant across the country. Canadian pharmacists are, now more than ever, poised and primed to provide care integrated with the rest of the primary health care system. However, the self-regulation of the profession of pharmacy is also a provincial/territorial mandate, making progress toward integration of pharmacists into the primary care system incongruent across jurisdictions. Among 11,000 pharmacies, Canada's 28,000 community pharmacists possess varying authority to prescribe, administer, and monitor drug therapies as an extension to their traditional dispensing role. Expanded professional services offered at most community pharmacies include medication reviews, minor/common ailment management, pharmacist prescribing for existing prescriptions, smoking cessation counselling, and administration of injectable drugs and vaccinations. Barriers to widely offering these services include uncertainties around remuneration, perceived skepticism from other providers about pharmacists' skills, and slow digital modernization including limited access by pharmacists to patient health records held by other professionals. Each province/territory enables pharmacists to offer these services under specific legislation, practice standards, and remuneration models unique to their jurisdiction. There is also a small, but growing, number of pharmacists across the country working within interdisciplinary primary care teams. To achieve meaningful, consistent, and seamless integration into the interdisciplinary model of Canadian primary health care reform, pharmacy advocacy groups across the country must coordinate and collaborate on a harmonized vision for innovation in primary care integration, and move toward implementing that vision with ongoing collaboration on primary health care initiatives, strategic plans, and policies. Canadians deserve to receive timely, equitable, and safe interdisciplinary care within a coordinated primary health care system, including from their pharmacy team

Impact of Pharmacist-Led Cognitive Behavioural Therapy for Chronic Insomnia.

BACKGROUND: Chronic insomnia is a common medical condition that negatively impacts quality of life and daytime function. Access to the first-line treatment for insomnia, cognitive behavioural therapy (CBT-i), is limited. Pharmacists are well positioned to provide this service, but evidence regarding pharmacist delivered CBT-i is sparse. The aim of this study was to evaluate the effectiveness of CBT-i delivered by pharmacists practicing in an outpatient clinic setting. METHODS: This study was a retrospective chart audit of adult patients with chronic insomnia who received CBT-i from a pharmacist at one of two outpatient clinics in Canada. The primary endpoints were the differences between patient self-reported sleep diary parameters and utilization of hypnotic medications before and after CBT-i was delivered. The differences in patient reported sleep parameters were compared using Wilcoxon Signed Rank test and paired samples t-test and changes in hypnotic utilization was compared using McNemar Chi-square test. RESULTS: 183 patients were referred for CBT-i and attended an initial appointment with a pharmacist. Of these, 105 did not receive the CBT-i. This resulted in 78 patients who met the inclusion criteria. Changes in sleep diary parameters were all statistically significantly improved after patients received CBT-i, except for total sleep time. Hypnotic medication use was also reduced. At baseline, 71.8% (n=56/78) of patients were taking one or more hypnotic medications compared to 52.6% (n=41/78) after CBT-i (p=0.0003). DISCUSSION: The results of this study provide preliminary evidence that pharmacists working in an outpatient clinic setting may be able to effectively deliver CBT-i for patients with chronic insomnia. The external validity of these results is limited by the observational study design and the inclusion of pharmacists practicing in outpatient clinics, which is not the setting where most pharmacists currently practice. CONCLUSION: This observational study found improvements in sleep quality and efficiency, as well as, a reduction in hypnotic medication use, in patients who received CBT-i from pharmacists practicing in an outpatient clinic setting. Future randomized, controlled trials should evaluate the impact of CBT-i in a larger sample of patients, provided by pharmacists practicing in both outpatient clinics and community pharmacies.

Impact of the SIMPL-SYNC Refill Synchronization Program on medication adherence: A pragmatic randomized controlled trial.

OBJECTIVE: To determine the impact of the SIMPL-SYNC refill synchronization (SSRS) service compared with that of usual care (UC) on medication adherence when applied as an opt-out strategy among patients receiving chronic medications. DESIGN: This was a pragmatic randomized controlled trial. SETTING AND PARTICIPANTS: The study was conducted in 2 community pharmacies located in Saskatchewan, Canada. Eligible patients were chronic medication users visiting the study pharmacies. OUTCOME MEASURES: The primary outcome was the percentage of individuals achieving optimal adherence to all eligible study medications. Eligible study medications included 22 commonly used medication classes used to treat diverse conditions. Adherence was assessed for each medication class after 300 days using the proportion of days covered (PDC). Optimal adherence was defined as PDC ≥ 80%. RESULTS: A total of 488 patients were screened for eligibility, and 190 patients were included in the intention-to-treat analysis (95 in SSRS, 95 in UC). The mean age of participants was 59 years, and 34% (65/190) were older than 65 years. A total of 574 individual adherence observations representing the 22 eligible study medication classes were generated from the 190 study participants. The percentage of individuals achieving optimal adherence to all their eligible study medications was 50.5% (48/95) in the SSRS group versus 44.2% (42/95) in the UC group (P = 0.383). Similarly, no statistically significant difference was observed in a per-protocol analysis assessing people who participated fully in the service; the percentage of individuals achieving optimal adherence to all their eligible study medications was 55.1% (38/69) in SSRS versus 40.7% (33/81) in UC (P = 0.080). Patient refusal of the refill synchronization services was common among randomized patients. CONCLUSION: SSRS service failed to detect a robust improvement in medication adherence when delivered using an opt-out strategy. However, small improvements in adherence or benefits to specific subgroups of patients could not be ruled out.

Community pharmacists' experiences with the Saskatchewan Medication Assessment Program.

BACKGROUND: The Saskatchewan Medication Assessment Program (SMAP) is a publicly funded community pharmacy-based medication assessment service with limited previous evaluation. The purpose of this study was to explore community pharmacists' experiences with the SMAP. METHODS: Online, self-administered questionnaire that consisted of a combination of 53 Likert scale and free-text questions. All licensed pharmacists who were practising in a community pharmacy setting in Saskatchewan were eligible to participate. RESULTS: Response rate was 20.3% (n = 228/1124). Most respondents agreed that the SMAP is achieving all of its intended purposes. For example, 89.7% agreed that the SMAP improved medication safety for patients who receive the service. Most pharmacists enjoyed performing the assessments (84.6%) and were confident in their ability to identify drug-related problems (88.3%). Pharmacists reported lack of time, patients having difficulty coming to the pharmacy and restrictive eligibility criteria as the top barriers to the SMAP. Good teamwork, employer support and personal professional commitment were the top recognized facilitators. Respondents made several suggestions to improve the SMAP in the free-text areas of the questionnaire. CONCLUSIONS: Community pharmacists in Saskatchewan were positive and confident about performing medication assessments, and most agreed that the SMAP is achieving all of the intended purposes. Respondents also identified several barriers to providing SMAP services, which have resulted in specific recommendations that should be addressed to improve the program.

Vitamin and mineral supplement use in medically complex, community-living, older adults.

Individuals who take medications may benefit from using vitamin and/or mineral supplements (VMS) yet excess supplementation can lead to overuse (daily intake exceeding the tolerable upper intake level (UL)). This study assessed VMS use of medically complex, community-living, older adults. A chart review of 229 patients ≥50 years with new medication assessments between 2014 and 2017 indicated that 76.9% of patients used ≥1 VMS daily. The UL for one or more nutrients was exceeded by 39.8% of supplement users.

Student perceptions of an experiential education clinic within a pharmacy school.

BACKGROUND AND PURPOSE: Pharmacy schools would benefit from new models of experiential education. The University of Saskatchewan (Canada) recently opened a patient care clinic called the Medication Assessment Centre (MAC) as new experiential education model. The purpose of this paper is to describe the structure and function of the MAC and to report program evaluation data. EDUCATIONAL ACTIVITY AND SETTING: The MAC is a unique application of an existing experiential education model in that it is an pharmacist-run ambulatory clinic (which is common) that is physically located on campus amongst the classrooms and supervised by pharmacy faculty (which is unique). Students are all required to participate in the clinic on a regular basis, in between lectures, throughout the four years of the pharmacy program. FINDINGS: Students were invited to participate in one of five focus groups to assess the value of the experience. Transcripts were analyzed using thematic analysis, and the results identified strong satisfaction amongst students. The overall themes fell into three categories: (1) aspects that students liked, (2) aspects that students found challenging, and (3) positive impact on student learning. Previously published studies have found strong support for the MAC amongst patients and physicians. SUMMARY: Students felt that a faculty supervised experiential education clinic that is physically located within their pharmacy school was a valuable learning experience. This paper provides a description of how the MAC has been integrated into an existing pharmacy curriculum, which may be valuable to schools contemplating a similar addition to existing experiential learning.

Family physician perceptions of a medication assessment clinic located within a pharmacy school.

OBJECTIVE: To determine if the clinical services provided at a patient care clinic run by pharmacy faculty and students are valuable to family physicians. DESIGN: Paper-based postal survey. SETTING: The Medication Assessment Centre located within the College of Pharmacy and Nutrition at the University of Saskatchewan in Saskatoon. PARTICIPANTS: Family physicians who had more than 1 patient who underwent a complete assessment at the Medication Assessment Centre between April 1 and October 26, 2015, were included in the study. MAIN OUTCOME MEASURES: Family physician experience and satisfaction based on quantitative analysis of 6 Likert scale survey questions and thematic analysis of 2 open-ended survey questions. RESULTS: A total of 81 questionnaires were mailed to family physicians, with a response rate of 43.2% (n = 35). Respondents reported a very high level of support and satisfaction with the clinical pharmacist program; most (88.6%) stated that it helped them to improve the health of their patients. CONCLUSION: The family physicians who responded to the questionnaire perceived the services provided at the patient care clinic located within the pharmacy school at the University of Saskatchewan to be valuable to their practices.
