Geographic and temporal variation in the treatment and outcomes of atrial fibrillation: a population-based analysis of national quality indicators
The objective of this study was to assess for potential geographic variation in the quality of atrial fibrillation care in Alberta, Canada.METHODS: In a population-based cohort of adults (age ≥ 18 yr) with incident nonvalvular atrial fibrillation (NVAF) diagnosed between Apr. 1, 2008, and Mar. 31, 2016, in Alberta, we investigated the variation in national quality indicators of atrial fibrillation care developed by the Canadian Cardiovascular Society.

Secondary prevention treatment after acute stroke in older South Asian, Chinese and other Canadians: a retrospective data analysis.
Abstract BACKGROUND: Little is known about whether there are differences in medication use between older patients of Chinese descent, those of South Asian descent and other Canadian patients after acute ischemic or primary intracerebral hemorrhagic stroke. The aim of this population-based study was to evaluate potential ethnic differences in secondary prevention pharmacotherapy after acute stroke. METHODS: Using health administrative data, we conducted a retrospective analysis of all patients aged 66 years or more admitted to hospital with acute stroke in Ontario (1997-2011) and British Columbia (1997-2009). ...

Screening for atrial fibrillation in Canadian pharmacies: an economic evaluation.
The objective of this study was to conduct an economic evaluation of the Program for the Identification of 'Actionable' Atrial Fibrillation in the Pharmacy Setting (PIAAF-Pharmacy), which screened 1145 participants aged 65 years or more at 30 community pharmacies in Ontario and Alberta between October 2014 and April 2015. METHODS: We used a 2-part decision model to evaluate the short- and long-term costs and quality-adjusted life-years (QALYs) of a pharmacy screening program for atrial fibrillation compared to no screening. Data from the PIAAF-Pharmacy study were used for the short-term model, and the relevant literat...
