Pharmacist intervention for glycaemic control in the community (the RxING study)
OBJECTIVE: To determine the effect of a community pharmacist prescribing intervention on glycaemic control in patients with poorly controlled type 2 diabetes. DESIGN: Pragmatic, before–after design. SETTING: 12 community pharmacies in Alberta, Canada. PARTICIPANTS: Type 2 diabetes receiving oral hypoglycaemic medications and with glycated haemoglobin (HbA1c) of 7.5–11%.INTERVENTION: Pharmacists systematically identified potential candidates by inviting patients with type 2 diabetes to test their HbA1c using validated point-of-care technology. Pharmacists prescribed 10 units of insulin glargine at bedtime, adjusted by increments of 1 unit daily to achieve a morning fasting glucose of ≤5.5 mmol/L. The patients were followed up at 2, 4, 8, 14, 20 and 26 weeks. PRIMARY OUTCOME: Change in HbA1c from baseline to week 26. SECONDARY OUTCOMES: Proportion of patients achieving target HbA1c, changes in oral hypoglycaemic agents, quality of life and patient satisfaction, persistence on insulin glargine, number of insulin dosage adjustments per patient and number of hypoglycaemic episodes.RESULTS: We screened 365 patients of whom 111 were eligible. Of those, 100 (90%) were enrolled in the study; all 11 patients who did not consent refused to use insulin. Average age was 64 years (SD 10.4), while average diabetes duration was 10.2 years (SD 7). HbA1c was reduced from 9.1% (SD 1) at baseline to 7.3% (SD 0.9); a change of 1.8% (95% CI 1.4 to 2, p<0.001). Fasting plasma glucose was reduced from 11 (SD 3.3) to 6.9 mmol/L (SD 1.8); a change of 4.1 mmol/L (95% CI of 3.3 to 5, p=0.007). Fifty-one per cent of the patients achieved the target HbA1c of ≤7% at the end of the study.CONCLUSIONS: This is the first completed study of independent prescribing by pharmacists. Our results showed similar improvements in glycaemic control as previous physician-led studies. RxING provides further evidence for the benefit of pharmacist care in diabetes
Pharmacist interventions to improve hypertension management: protocol for a systematic review of randomised controlled trials
INTRODUCTION: Hypertension management remains a major public health challenge in primary care. Innovative interventions to improve blood pressure (BP) control are needed. One approach is through community-based models of care with the involvement of pharmacists and other non-physician healthcare professionals. Our objective is to systematically review the evidence of the impact of pharmacist care alone or in collaboration with other healthcare professionals on BP among hypertensive outpatients compared with usual care. Because these interventions can be complex, with various components, the effect size may differ between the type of interventions. One major focus of our study will be to assess carefully the heterogeneity in the effects of these interventions to identify which ones work best in a given healthcare setting. METHODS AND ANALYSIS: Systematic searches of the Medical Literature Analysis and Retrieval System Online (MEDLINE), Excerpta Medica (Embase) and Central Register of Controlled Trials (CENTRAL) databases will be conducted. Randomised controlled trials assessing the effect of pharmacist interventions on BP among outpatients will be included. Examples for pharmacist interventions are patient education, feedback to physician and medication management. The outcome will be the change in BP or BP at follow-up or BP control. Results will be synthesised descriptively and, if appropriate, will be pooled across studies to perform meta-analyses. If feasible, we will also perform a network meta-analysis to compare interventions that have not been compared directly head-to-head by using indirect evidence. Heterogeneity in the effect will be evaluated through prespecified subgroup and stratified analyses, accounting notably for the type and intensity of interventions, patients' characteristics and healthcare setting. ETHICS AND DISSEMINATION: Ethical approval is not required as the results will be drawn from currently available published literature. Outcomes of the review will be shared through peer-reviewed journal and used for implementation policy. PROSPERO REGISTRATION NUMBER: CRD42021279751
Effect of Adding Pharmacists to Primary Care Teams on Blood Pressure Control in Patients With Type 2 Diabetes: A randomized controlled trial
Pharmacy practice research - A call to action.
Pharmacists have a societal duty of care. How to best provide that type of care requires scientific study. Pharmacy practice is a scientific discipline that studies the different aspects of the practice of pharmacy, and its impact on health care systems, medicine use, and patient care. Its scope has expanded globally to encompass clinical, behavioural, economic, and humanistic implications of the practice of pharmacy, as well as practice change and implementation in routine practice of innovations such as health interventions and patient-care services. The development, impact evaluation, implementation, and sustainability of health interventions and patient-care services represents a key research area for pharmacy practice. An approach for conducting these is provided. There is evidence that collaborative national and international research in this area is growing, showing an increased contribution to global health research. The role of universities and pharmacy professional associations in supporting the advancement of pharmacy through pharmacy practice research is also discussed. Finally, a call to action for pharmacy practice research, education, and practice is made
Pharmacy study of natural health product adverse reactions (SONAR): a cross-sectional study using active surveillance in community pharmacies to detect adverse events associated with natural health products and assess causality
OBJECTIVES: To investigate the rates and causality of adverse event(s) (AE) associated with natural health product (NHP) use, prescription drug use and concurrent NHP-drug use through active surveillance in community pharmacies. DESIGN: Cross-sectional study of screened patients. SETTING: 10 community pharmacies across Alberta and British Columbia, Canada from 14 January to 30 July 2011. PARTICIPANTS: The participating pharmacy staff screened consecutive patients, or agents of patients, who were dropping or picking up prescription medications.PRIMARY OUTCOME MEASURES: Patients were screened to determine the proportions of them using prescription drugs and/or NHPs, as well as their respective AE rates. All AEs reported by the screened patients who took a NHP, consented to, and were available for, a detailed telephone interview (14%) were adjudicated fully to assess for causality.RESULTS: Over a total of 105 pharmacy weeks and 1118 patients screened, 410 patients reported taking prescription drugs only (36.7%; 95% CI 33.9% to 39.5%), 37 reported taking NHPs only (3.3%; 95% CI 2.4% to 4.5%) and 657 reported taking prescription drugs and NHPs concurrently (58.8%; 95% CI 55.9% to 61.6%). In total, 54 patients reported an AE, representing 1.2% (95% CI 0.51% to 2.9%), 2.7% (95% CI 0.4% to 16.9%) and 7.3% (95% CI 5.6% to 9.6%) of each population, respectively. Compared with patients who reported using prescription drugs, the patients who reported using prescription drugs and NHPs concurrently were 6.4 times more likely to experience an AE (OR; 95% CI 2.52 to 16.17; p<0.001). Combined with data from Ontario, Canada, a national proportion was calculated, which found that 45.4% (95% CI 43.8% to 47.0%) of Canadians who visit community pharmacies take NHPs and prescription drugs concurrently, and of those, 7.4% (95% CI 6.3% to 8.8%) report an AE.CONCLUSIONS: A substantial proportion of community pharmacy patients use prescription drugs and NHPs concurrently; these patients are at a greater risk of experiencing an AE. Active surveillance provides a means of detecting such AEs and collecting high-quality data on which causality assessment can be based

Metformin treatment in diabetes and heart failure: when academic equipoise meets clinical reality
<p>Abstract</p> <p>Objective</p> <p>Metformin has had a 'black box' contraindication in diabetic patients with heart failure (HF), but many believe it to be the treatment of choice in this setting. Therefore, we attempted to conduct a pilot study to evaluate the feasibility of undertaking a large randomized controlled trial with clinical endpoints.</p> <p>Study Design</p> <p>The pilot study was a randomized double blinded placebo controlled trial. Patients with HF and type 2 diabetes were screened in hospitals and HF clinics in Edmonton, Alberta, Canada (population ~1 million). Major exclusion criteria included the current use of insulin or high dose metformin, decreased renal function, or a glycosylated hemoglobin <7%. Patients were to be randomized to 1500 mg of metformin daily or matching placebo and followed for 6 months for a variety of functional outcomes, as well as clinical events.</p> <p>Results</p> <p>Fifty-eight patients were screened over a six month period and all were excluded. Because of futility with respect to enrollment, the pilot study was abandoned. The mean age of screened patients was 77 (SD 9) years and 57% were male. The main reasons for exclusion were: use of insulin therapy (n = 23; 40%), glycosylated hemoglobin <7% (n = 17; 29%) and current use of high dose metformin (n = 12; 21%). Overall, contraindicated metformin therapy was the most commonly prescribed oral antihyperglycemic agent (n = 27; 51%). On average, patients were receiving 1,706 mg (SD 488 mg) of metformin daily and 12 (44%) used only metformin.</p> <p>Conclusion</p> <p>Despite uncertainty in the scientific literature, there does not appear to be clinical uncertainty with regards to the safety or effectiveness of metformin in HF making a definitive randomized trial virtually impossible.</p> <p>Trial registration</p> <p>ClinicalTrials.gov Identifier: NCT00325910</p
Improving hypertension management through pharmacist prescribing; the rural alberta clinical trial in optimizing hypertension (Rural RxACTION): trial design and methods
<p>Abstract</p> <p>Background</p> <p>Patients with hypertension continue to have less than optimal blood pressure control, with nearly one in five Canadian adults having hypertension. Pharmacist prescribing is gaining favor as a potential clinically efficacious and cost-effective means to improve both access and quality of care. With Alberta being the first province in Canada to have independent prescribing by pharmacists, it offers a unique opportunity to evaluate outcomes in patients who are prescribed antihypertensive therapy by pharmacists.</p> <p>Methods</p> <p>The study is a randomized controlled trial of enhanced pharmacist care, with the unit of randomization being the patient. Participants will be randomized to enhanced pharmacist care (patient identification, assessment, education, close follow-up, and prescribing/titration of antihypertensive medications) or usual care. Participants are patients in rural Alberta with undiagnosed/uncontrolled blood pressure, as defined by the Canadian Hypertension Education Program. The primary outcome is the change in systolic blood pressure between baseline and 24 weeks in the enhanced-care versus usual-care arms. There are also three substudies running in conjunction with the project examining different remuneration models, investigating patient knowledge, and assessing health-resource utilization amongst patients in each group.</p> <p>Discussion</p> <p>To date, one-third of the required sample size has been recruited. There are 15 communities and 17 pharmacists actively screening, recruiting, and following patients. This study will provide high-level evidence regarding pharmacist prescribing.</p> <p>Trial Registration</p> <p>Clinicaltrials.gov <a href="http://www.clinicaltrials.gov/ct2/show/NCT00878566">NCT00878566</a>.</p
