Our objective was to explore the relation between a change in access to a primary care physician and continuity of care.Methods: We conducted a retrospective cohort study among physicians in a primary care network in southwest Alberta who measured access consistently between 2009 and 2016. We used time to the third next available appointment as a measure of access to physicians. We calculated the provider and clinic continuity, discontinuity and emergency department use based on the physicians{\textquoteright} own panels. Physicians who improved, worsened or maintained their level of access within a given year were assessed in multilevel models to determine the association with continuity of care at the physician and clinic levels and the emergency department.Results: We analyzed data from 190 primary care physicians. Physicians with improved access increased provider continuity by 6.8\% per year, reduced discontinuity by 2.1\% per year, and decreased emergency department encounters by 78 visits per 1000 patients per year compared to physicians with stable access. Physicians with worsening access had a 6.2\% decrease in provider continuity and an increased number of emergency department encounters (64 visits per 1000 panelled patients per year) compared to physicians with stable access.Interpretation: Changes in access to primary care can affect whether patients seek care from their own physician, from another clinic or at the emergency department. Improving access by reducing the delay in obtaining an appointment with one{\textquoteright}s primary care physician may be one mechanism to improve continuity of care.}, URL = {https://www.cmajopen.ca/content/8/4/E722}, eprint = {https://www.cmajopen.ca/content/8/4/E722.full.pdf}, journal = {Canadian Medical Association Open Access Journal} }
