Background: Despite the shift towards direct-acting anticoagulants, warfarin remains widely used in Canada and is traditionally managed by family physicians through laboratory-based international normalized ratio (INR) testing. The Community Pharmacy Anticoagulation Management Service (CPAMS) in Nova Scotia represents an innovative approach, enabling community pharmacists to conduct point-of-care (POC) INR testing and manage warfarin therapy. A potential benefit of this approach is the opportunity to identify non-warfarin medication therapy problems (nwMTPs) during routine visits.

Method: We conducted a prospective, multicentre, observational study across 40 community pharmacies in Nova Scotia, part of CPAMS's second phase. Pharmacists documented nwMTPs identified in patients with atrial fibrillation during routine POC INR visits using the Qualtrics Insight Platform, categorizing them by indication, effectiveness, safety, or adherence, alongside corresponding interventions.

Results: Over 6 months, 43 nwMTPs were submitted from 13 unique pharmacies. There were 3404 POC INR tests in patients with atrial fibrillation, yielding an estimated nwMTP detection rate of 1.26 (95% CI, 0.69 to 2.32) per 100 INR tests. The most common nwMTP category was "Indication," primarily requiring additional therapy. Pharmacists frequently intervened by recommending medication adjustments or providing patient education.

Discussion: The findings highlight a modest, yet potentially significant role of pharmacists in detecting and managing diverse MTPs during focused warfarin management assessments. The predominance of indication-related problems underscores unmet therapeutic needs in patients on warfarin.

Conclusion: This study illustrates the potential of pharmacist-led POC INR testing in community settings to identify and address nwMTPs, contributing to comprehensive patient care.

Background: Burnout among pharmacists is increasingly pertinent, with growing demand for effective interventions. Burnout can lead to reduced productivity, increased job turnover, medical errors, poor patient satisfaction, and other negative outcomes for patients and providers. Growing attention to burnout in the pharmacy profession highlights the need for personal, organizational, and systemic solutions. However, the uptake and relative efficacy of different approaches remain unclear, particularly within community pharmacy practice. This study sought the viewpoint of community pharmacy leaders (i.e., community pharmacy managers, district managers, franchisees, owners, and executives from various pharmacy organizations) to characterize burnout from their perspectives.

Methods: This qualitative study followed a grounded theory approach. Community pharmacy leaders were interviewed using a semistructured format to gather in-depth insights into their experiences and perspectives on burnout and engagement.

Results: Sixteen people were interviewed; interviews lasted 30 to 65 minutes, averaging 51 minutes long. Six themes were identified: perceived disconnection between front-line staff and pharmacy decision-makers, overwhelming work demands, cautious optimism toward the expanding scope of pharmacy practice, the importance of employee recognition and appreciation, appropriateness and use of existing work resources, and multimodal, systemic responsibility and solutions to burnout.

Conclusion: Addressing burnout requires a multifaceted approach involving personal, organizational, and systemic interventions. Evidence from this study provides valuable insights into the feasibility and efficacy of specific interventions, informing future strategies to enhance workplace well-being and engagement. The study highlights the importance of managing job demands and maximizing resources, emphasizing that personal approaches alone are insufficient and that organizational and systemic interventions are crucial.

Background: Early detection of chronic obstructive pulmonary disease (COPD) is a strategy to address the increasing human and economic costs of this condition. This study aimed to inform pharmacists' case-finding strategies by providing an overview of case-finding approaches by health care practitioners.

Methods: A scoping review was conducted based on the Joanna Briggs Institute and the PRISMA Extension for Scoping Reviews (PRISMA ScR) guidelines. Included studies were analyzed under the following themes: population characteristics, inclusion and exclusion criteria, setting, case-finding strategies and yield, health care practitioners involved, interprofessional collaboration and the provision of preventive services. Studies were then characterized by highest yields (the weighted average of each approach expressed as a percentage of the total number of new COPD cases divided by the total number of patients screened using the same approach).

Results: The screening process produced 170 eligible studies. Twenty case-finding approaches with average yields of new COPD cases ranging from 3.8% to 29% were identified. The approach with the highest yield involved the use of a questionnaire, peak flow meter and pre-post spirometry. In 14 of these approaches, the process was initiated with the use of questionnaires. In many of the studies, case-finding was targeted at high-risk and/or symptomatic patients. Characteristics of studies with the highest case-finding yields included provider education/training, patient education, active screening, multistep approaches to case-finding, provider engagement, diagnostic criteria by guidelines and engagement of other health care practitioners.

Conclusion: In our scoping review of case-finding methods for patients with COPD, we found the greatest yield from pre-post spirometry following initial screening with a peak flow meter and questionnaire. Pharmacists and health researchers can use these approaches to identify high-risk patients for interventions.

Background: Approximately 10% of individuals with hypertension are expected to have resistant hypertension (RH). Many have pseudo-resistant hypertension (p-RH) due to a variety of factors. To date, the prevalence of p-RH and optimal diuretic therapy in primary care have not been studied.

Methods: A retrospective chart review was conducted, including patients referred to the hypertension clinic at the Centre for Family Medicine (CFFM) Family Health Team in Kitchener, ON, from January 2010 to September 2020. Individuals ≥18 years old referred to clinic by their family physician or other health care provider with 2 consecutive blood pressure (BP) readings of ≥140/90 mmHg despite using ≥3 antihypertensive agents were included.

Results: Fifty-one patients taking ≥3 antihypertensive agents were referred during the study timeframe. Forty-one patients had ≥2 consecutive BP readings of ≥140/90 and were classified as having presumed RH. Of these, 24 patients (59%) had p-RH after BP was measured systematically in the hypertension clinic. Of the 17 with RH, 5 (29%) were prescribed optimal diuretic therapy upon referral. Most common clinic interventions included initiating or adjusting the dose of a diuretic (47%), adding a different antihypertensive agent (27%) or discontinuing an antihypertensive agent due to side effects (24%).

Discussion: To our knowledge, this is the first time that the prevalence of p-RH and optimal diuretic therapy have been studied in primary care. p-RH was common and diuretic therapy was underused in RH.

Conclusion: This study suggests that p-RH is prevalent and diuretic therapy underused in primary care. Systematic BP measurement and optimization of diuretic therapy should be prioritized prior to specialist referral.

Background: Undervaccination is a public health issue that disproportionately affects underserved populations. Pharmacists are accessible health care professionals who have the potential to better reach communities. The aim of this study is to understand how organizational obstacles influence the pharmacist's ability to meet underserved clients' vaccination needs in community pharmacy.

Methods: We conducted semi-structured interviews with key stakeholders in Quebec. Results were codified according to domains of the Consolidated Framework for Implementation Research.

Results: Fourteen interviews were carried out with representatives from pharmacy associations, pharmacy chains and banners, integrated health and social service centres, and local Quebec Public Health departments. Barriers to promoting vaccination were identified in four areas: 1) vaccine service logistics, 2) the pharmacy setting, 3) external influences and 4) pharmacist's knowledge and beliefs.

Discussion: Technological tools accessible to pharmacists are sufficient but not user-friendly due to the lack of integration between the pharmacy software, the vaccine registry and the provincial appointment system. Technology limits access to vaccination for certain underserved populations. Moreover, the incentives linked to vaccination do not favour the vaccination of difficult-to-reach clients and they limit pharmacists' ability to be proactive with vaccine recommendations. Pharmacists are more inclined to participate in mass vaccination campaigns, and delegating vaccine administration to nurses and technicians allows pharmacies to financially break even. Certain services such as travel health vaccination require an extended set of knowledge, which creates resistance for some pharmacists to integrate the role.

Conclusion: Pharmacists are well-placed to improve vaccination uptake, but several technological and organizational barriers limit their ability to provide vaccination services and reach underserved communities. A better alignment between incentives and proactive promotion should be put forward to encourage pharmacists to actively identify and reach underserved populations.
