Strategies to guide the successful implementation of deprescribing in community practice: Lessons learned from the front line.

Background: Sustainable implementation of new professional services into clinical practice can be difficult. In 2019, a population-wide initiative called SaferMedsNL was implemented across the province of Newfoundland and Labrador (NL), to promote appropriate medication use. Two evidence-based interventions were adapted to the context of NL to promote deprescribing of proton pump inhibitors and sedatives. The objective of this study was to identify and prioritize which actions supported the implementation of deprescribing in community practice for pharmacists, physicians and nurse practitioners across the province. Methods: Community pharmacists, physicians and nurse practitioners were invited to participate in virtual focus groups. Nominal Group Technique was used to elicit responses to the question: "What actions support the implementation of deprescribing into the daily workflow of your practice?" Participants prioritized actions within each group while thematic analysis permitted comparison across groups. Results: Five focus groups were held in fall 2020 involving pharmacists (n = 11), physicians (n = 7) and nurse practitioners (n = 4). Participants worked in rural (n = 10) and urban (n = 12) settings. The different groups agreed on what the top 5 actions were, with the top 5 receiving 68% of the scores: (1) providing patient education, (2) allocating time and resources, (3) building interprofessional collaboration and communication, (4) fostering patient relationships and (5) aligning with public awareness strategies. Conclusion: Pharmacists, physicians and nurse practitioners identified similar actions that supported implementing evidence-based deprescribing into routine clinical practice. Sharing these strategies may help others embed deprescribing into daily practice and assist the uptake of medication appropriateness initiatives by front-line providers.

Barriers and enablers to testing for hepatitis C virus infection in people who inject drugs - a scoping review of the qualitative evidence.

BACKGROUND: Injection drug use is the primary mode of transmission of hepatitis C virus (HCV) infection in the developed world and guidelines recommend screening individuals with current or history of injection drug use for HCV; however, the majority of those living with HCV in Canada are not aware of their positive status. This low level of HCV status awareness suggests that screening is not effective with current testing strategies. The aim of this review is to determine what barriers and enablers people who inject drugs (PWID) experience surrounding testing for HCV to help inform the development of an engaging testing strategy. METHODS: Comprehensive literature searches were conducted using Medline, Embase and CINAHL in February 2021. Included studies investigated the barriers and enablers to testing for HCV in PWID and the experiences of PWID in testing for HCV. Studies were included if they were qualitative or mixed-methods design, involved people with current injection drug use or those with a history of injecting drugs, and were written in the English language. Studies were compared and common themes were coded and analyzed. RESULTS: The literature search resulted in 1554 citations and ultimately nine studies were included. Common barriers included self-perception of low risk for HCV, fear of diagnosis, stigma associated with IV drug use and HCV, antipathy in relation to mainstream health care services, limited knowledge about HCV, lack of rapport with provider, lack of motivation or competing priority of drug use, and limited awareness of new treatment options. Common enablers to testing included increasing awareness of HCV testing and treatment and providing positive narratives around HCV care, positive rapport with provider, accessible testing options and individualized care. CONCLUSION: While there has been some qualitative research on barriers and enablers to testing for HCV in PWID more research is needed to focus on this research question as a primary objective in order to provide more understanding from the participant's perspective.

Community pharmacists' acceptance of prescribing pre-exposure prophylaxis (PrEP) for human immunodeficiency virus (HIV).

Background: Pre-exposure prophylaxis (PrEP) for human immunodeficiency virus (HIV) prevention is highly effective. Pharmacists can increase PrEP accessibility through pharmacist prescribing. This study aimed to determine pharmacists' acceptance of a pharmacist PrEP prescribing service in Nova Scotia. Methods: A triangulation mixed methods study consisting of an online survey and qualitative interviews was conducted with Nova Scotia community pharmacists. The survey questionnaire and qualitative interview guide were underpinned by the 7 constructs of the Theoretical Framework of Acceptability (affective attitude, burden, ethicality, opportunity costs, intervention coherence, perceived effectiveness and self-efficacy). Survey data were analyzed descriptively and with ordinal logistic regression to determine associations between variables. Interview transcripts were deductively coded according to the same constructs and then inductively coded to identify themes within each construct. Results: A total of 214 community pharmacists completed the survey, and 19 completed the interview. Pharmacists were positive about PrEP prescribing in the constructs of affective attitude (improved access), ethicality (benefits communities), intervention coherence (practice alignment) and self-efficacy (role). Pharmacists expressed concerns about burden (increased workload), opportunity costs (time to provide the service) and perceived effectiveness (education/training, public awareness, laboratory test ordering and reimbursement). Conclusion: A PrEP prescribing service has mixed acceptability to Nova Scotia pharmacists yet represents a model of service delivery to increase PrEP access to underserved populations. Future service development must consider pharmacists' workload, education and training as well as factors relating to laboratory test ordering and reimbursement.

Target users' acceptance of a pharmacist-led prescribing service for pre-exposure prophylaxis (PrEP) for human immunodeficiency virus (HIV).

Background: Pre-exposure prophylaxis (PrEP) for human immunodeficiency virus (HIV) is a highly effective way to reduce virus transmission. There have been increasing calls to improve access to PrEP in Canada. One way to improve access is by having more prescribers available. The objective of this study was to determine target users' acceptance of a PrEP-prescribing service by pharmacists in Nova Scotia. Methods: A triangulation, mixed-methods study was conducted consisting of an online survey and qualitative interviews underpinned by the Theoretical Framework of Acceptability (TFA) constructs (affective attitude, burden, ethicality, intervention coherence, opportunity cost, perceived effectiveness and self-efficacy). Participants were those eligible for PrEP in Nova Scotia (men who have sex with men or transgender women, persons who inject drugs and HIV-negative individuals in serodiscordant relationships). Descriptive statistics and ordinal logistic regression were used to analyze survey data. Interview data were deductively coded according to each TFA construct and then inductively coded to determine themes within each construct. Results: A total of 148 responses were captured by the survey, and 15 participants were interviewed. Participants supported pharmacists' prescribing PrEP across all TFA constructs from both survey and interview data. Identified concerns related to pharmacists' abilities to order and view lab results, pharmacists' knowledge and skills for sexual health and the potential for experiencing stigma within pharmacy settings. Conclusion: A pharmacist-led PrEP-prescribing service is acceptable to eligible populations in Nova Scotia. The feasibility of PrEP prescribing by pharmacists should be pursued as an intervention to increase access to PrEP.

Expanding access to HIV testing through Canadian community pharmacies: findings from the APPROACH study.

BACKGROUND: There is a need for acceptable and feasible HIV testing options to ensure people living with HIV know their status so they can access care. Pharmacist-provided HIV point-of-care testing (POCT) may overcome testing barriers, including privacy concerns, testing wait times, and improve accessibility. In the APPROACH study, we aimed to develop and assess an HIV POCT program in community pharmacies for future scale up and evaluation. This paper describes the program uptake, participant and pharmacist experiences, and implementation factors. METHODS: A pharmacist-provided HIV POCT program was offered in 4 pharmacies in two Canadian provinces. A mixed methods design incorporated self-report questionnaire data, participant telephone interviews, pharmacist focus groups, workload analysis, and situational analysis to assess the uptake, acceptability and feasibility of the HIV POCT program. RESULTS: Over the 6-month pilot, 123 HIV tests were performed. One new case of HIV was identified; this participant was linked with confirmatory testing and HIV care. Participants were predominantly male (76%), with a mean age of 35 years. This was the first HIV test for 27% participants, and 75% were at moderate to very high risk of undiagnosed HIV infection, by Denver HIV Risk Score. Questionnaires and telephone interviews showed participants were very satisfied with the program; 99% agreed HIV POCT should be routinely offered in pharmacies and 78% were willing to pay for the service. Participants felt the pharmacy was convenient, discreet, and that the pharmacist was supportive and provided education about how to reduce their future risk. Pharmacists felt prepared, confident, and expressed professional satisfaction with offering HIV POCT. Community and public health supports, clear linkage to care plans to refer participants with positive HIV POCT results, and provision of counselling tools were important enabling factors for the program. Pharmacist remuneration, integration with existing healthcare systems, and support for ongoing promotion of HIV POCT availability in pharmacies were identified as needs for future scale-up and sustainability. CONCLUSIONS: A successful model of pharmacy-based POCT, including linkage to care, was developed. Further research is needed to determine the effectiveness and cost-effectiveness of this approach in finding new diagnoses and linking them with care. TRIAL REGISTRATION: Retrospectively registered with clinicaltrials.gov (NCT03210701) on July 6, 2017.

Patient satisfaction with chronic HIV care provided through an innovative pharmacist/nurse-managed clinic and a multidisciplinary clinic.

BACKGROUND: Pharmacist/nurse-led clinics are an established model for many chronic diseases but not yet for HIV. At our centre, patients with HIV are seen by a multidisciplinary team (physician, nurse, pharmacist, social worker) at least yearly. Some attend an HIV-specialist pharmacist/nurse clinic (or "nonphysician clinic," NPC) for alternate biannual visits. Our objective was to assess patient satisfaction with care received through both clinics. METHODS: The Patient Satisfaction Survey for HIV Ambulatory Care (assesses satisfaction with access to care, clinic visits and quality of care) was administered by telephone to adults who attended either clinic between January and July 2014. Descriptive statistics described patient characteristics and satisfaction scores. Fisher's exact test compared satisfaction scores between the NPC and multidisciplinary clinic (MDC). Multivariate logistic regression examined associations between overall satisfaction with care and clinic type and patient characteristics (e.g., age, disease duration). RESULTS: Respondents were very satisfied with the overall quality of HIV care in both the NPC and MDC (89% vs 93%, respectively, p = 0.6). Patients from both clinics expressed satisfaction with access to care, treatment plan input, their provider's knowledge of the newest developments in HIV care and explanation of medication side effects, with no significant differences noted. Significantly more MDC patients reported being asked about housing/finances, alcohol/drug use and whether they needed help disclosing their status. Patient characteristics were not significantly associated with satisfaction with overall quality of care. CONCLUSION: Patients are satisfied with both clinics, supporting NPC as an innovative model for chronic HIV care. Comparison of outcomes between clinics is needed to ensure high-quality care.

Patient attitudes regarding the role of the pharmacist and interest in expanded pharmacist services.

BACKGROUND: Pharmacists are consistently ranked among the most trusted professionals, and research shows high levels of satisfaction with pharmacist services. Studies have also shown that the public is generally unaware of the full range of roles and responsibilities of a pharmacist. The purpose of this study was to explore the public's knowledge and attitudes regarding the role of the community pharmacist and to determine their likelihood of using expanded pharmacist services. METHODS: Adults across Newfoundland and Labrador were surveyed by telephone. Survey questions addressed how frequently participants visited the pharmacy, understanding of duties undertaken by pharmacists, perceptions and attitudes regarding pharmacists as health care professionals, likelihood of using expanded pharmacist services and participant demographics. Comparisons were made between responses from urban and rural participants and frequent versus nonfrequent pharmacy users, to determine if there were any differences. RESULTS: The majority of participants were generally aware of what pharmacists do when filling prescriptions; those who visited the pharmacy more frequently appeared to be more informed. Participants indicated they would take advantage of the expanded services suggested, with greatest interest in receiving advice for minor ailment management and prescription refills from pharmacists. Results support the prevailing view that pharmacists are trusted health professionals who should have access to patients' health information to provide best care. CONCLUSION: The public is aware of aspects of the pharmacist's role, but opportunities exist to better educate the public on the knowledge, skills and unique professional abilities of pharmacists to support uptake of expanded pharmacist services.
