Purpose: To measure the impact of beliefs, expectations, side effects, and their combined effects on the risk for medication nonpersistence.
Patients And Methods: Using a cross-sectional design, individuals from Saskatchewan, Canada who started a new antihypertensive, cholesterol-lowering, or antihyperglycemic medication were surveyed about risk factors for nonpersistence including: (a) beliefs measured by a composite score of three questions asking about the threat of the condition, importance of the drug, and harm of the drug; (b) incident side effects attributed to treatment; and (c) expectations for side effects before starting treatment. Descriptive statistics and logistic regression models were used to quantify the influence of these risk factors on the outcome of nonpersistence.
Background: The overall impact of physician prescribers on population-level adherence rates are unknown. We aimed to quantify the influence of general practitioner (GP) physician prescribers on the outcome of optimal statin medication adherence.
Methods: We conducted a retrospective cohort study using health administrative databases from Saskatchewan, Canada.
Background: Drug discontinuation (i.e., nonpersistence) is often attributed to the emergence of adverse effects.

Methods: A multicenter randomized controlled trial tested the intervention delivered to patients undergoing assessment or waitlisted for kidney transplant.
Background: The Saskatchewan Medication Assessment Program (SMAP) compensates community pharmacists for medication reviews on eligible residents with the goal of optimizing patient care. Although medication reviews are meant to reduce risks associated with complex medication regimens, some patients may already be receiving specialized care from interdisciplinary health care teams from the renal programs in Saskatchewan.
Objective: A qualitative analysis was undertaken to examine the perceptions of health care providers about the SMAP process for patients receiving renal care in Saskatchewan.
Introduction: Adverse symptoms experienced by solid organ transplant recipients remain largely unexplored despite their purported frequency.
Objective: To characterize patient perspectives on adverse symptoms, identifying the most problematic symptoms and the perceived cause and treatability, and to evaluate their impact on quality of life (QoL) and medication adherence.
Methods: An electronic survey was distributed to members of the Canadian Transplant Association, to characterize perceptions on symptom experience (Modified Transplant Symptom Occurrence and Distress Scale), and QoL (Short Form-12), medication adherence (Basel Assessment of Adherence to Immunosuppressive Medications Scale), demographics, and clinical situation.
Objectives: The aim of this work was to determine whether: 1) blood glucose test strip use in the population is associated with hypoglycemia hospitalization rates, and 2) blood glucose test strip use among individuals is associated with a reduced risk of hypoglycemia hospitalization.
Methods: Administrative databases from Saskatchewan, Canada, were used to ascertain population-level hypoglycemia hospitalizations and test strip utilization over the period from 1996 to 2014. For objective 1, a generalized linear model with generalized estimating equations was fit to provincial data stratified by age group, sex and year.
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.
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.

Background: In 2007, a drug benefit plan for Seniors (SDP) was launched in Saskatchewan, Canada. SDP capped out-of-pocket costs at $15 per prescription for individuals aged 65 and older.
Objectives: To quantify the impact of the SDP on chronic medication adherence.
Objective: To validate a case definition of multiple sclerosis (MS) using health administrative data and to provide the first province-wide estimates of MS incidence and prevalence for Saskatchewan, Canada.
Methods: We used population-based health administrative data between January 1, 1996 and December 31, 2015 to identify individuals with MS using two potential case definitions: (1) ≥3 hospital, physician, or prescription claims (Marrie definition); (2) ≥1 hospitalization or ≥5 physician claims within 2 years (Canadian Chronic Disease Surveillance System [CCDSS] definition). We validated the case definitions using diagnoses from medical records (n=400) as the gold standard.
Background: Information leaflets have been shown to positively or negatively impact adherence, depending on their content. The objective of this study was to perform an appraisal of the consumer information provided in COPD inhaler monographs.
Methods: COPD inhalers were identified from the Health Canada Drug Product Database.
Objectives: To describe trends in blood glucose test strip (TS) utilization and cost in Saskatchewan.
Methods: A retrospective analysis of TS use between January 1, 1996, and December 31, 2013, was conducted using population-based health administrative databases in Saskatchewan. The prescription drug database was used to describe the annual number of TS dispensations, the number of strips dispensed, the number of unique beneficiaries and the total costs.
The allure of natural products has captivated humans for centuries. Although they can be compatible with evidence-based care, attitudes surrounding natural products can seem almost mystical and may even be accompanied by contempt toward Western medicine. Considering the high volumes of natural products sold in community pharmacies, pharmacists can inject balanced information to minimize the mysticism and help patients make informed decisions.

Objectives: To describe medication adherence by the proportion of days covered before and after enrollment in a refill synchronization program.
Methods: We conducted a retrospective analysis of medication adherence in 2 pharmacies offering a refill synchronization program. The study population consisted of individuals who received 2 or more medications from any of 15 predefined medication classes within 6 months of enrollment in the synchronization program.
Study Objective: To test a brief intervention for preventing statin nonadherence among community pharmacy patrons.
Design: Prospective, cluster-randomized, controlled trial (the Community Pharmacists Assisting in Total Cardiovascular Health [CPATCH] trial).
Setting: Thirty community pharmacies in Saskatchewan, Canada.
Introduction: Low socioeconomic status (SES) should be a robust predictor of medication nonadherence because it shares key features with the theoretical origins of this phenomenon. However, population-based studies have demonstrated weak associations overall, possibly because SES is inadequately represented. We compared the performance of multiple versus single-domain measures of SES as predictors of statin adherence.
View Article and Find Full Text PDFThe evidence supporting a link between statin use and incident diabetes is seemingly robust; it has been observed in multiple prospective randomized trials and confirmed by meta-analyses. However, differences in survival among statin vs placebo-treated patients in randomized trials might have caused bias with respect to diabetes surveillance. Bias might have been further exaggerated from the strong association between diabetes and cardiovascular events, which were the primary end points in major statin trials.

Rationale: Chronic use of imatinib confers an important survival benefit for individuals with chronic myeloid leukemia. In Saskatchewan, the provincial cancer agency addresses important barriers to adherence by providing imatinib at no cost through specialized cancer centers.
Objective: To describe adherence to imatinib dispensed through the Saskatchewan Cancer Agency.
Background: Although conventional wisdom suggests that low socioeconomic status (SES) is a robust predictor of medication nonadherence, the strength of this association remains unclear.
Objectives: 1) To estimate the proportion of studies that identified SES as a potential risk indicator of nonadherence, 2) to describe the type of SES measurements, and 3) to quantify the association between SES and nonadherence to antihypertensive pharmacotherapy.
Methods: A systematic review and meta-analysis research design was used.
