  • Nonmetropolitan zone includes north, central, and south zones and metropolitan zone includes Calgary and Edmonton zones according to Alberta Health Services, the health authority for Alberta, Canada. Medium/large population center: consisting of a population of >30,000 people; small population center/rural area: consisting of a population of <29,999 people. Practice interest in the care of the elderly or geriatrics was on the basis of clinical practice interests reported by respondents and the College of Physicians and Surgeons of Alberta. Outcomes: sometimes/often/always a barrier compared with never/rarely a barrier (reference). Analysis was conducted using modified Poisson regression, with robust error variance. RR, relative risk; 95% CI, 95% confidence interval; —, excluded term.
