The Association Between Continuity of Care and Emergency Department Utilization Among Canadian Senior Adults

Continuity of care with a primary care physician is critical for appropriate healthcare utilization, particularly among seniors with complex health needs. This study examines the association between the length of care continuity and the usual place of care for minor health problems, focusing on emergency department (ED) use.

Data were drawn from the 2019-2020 Canadian Health Survey on Seniors (CHSS), a nationally representative 15-minute supplement to the Canadian Community Health Survey (CCHS) for Canadians aged 65 years and older. Of 245,639 selected households, 100,797 individuals responded to the CCHS (41.0%), and 41,635 of 45,863 eligible respondents completed the CHSS (90.8%). Minor health problems or nonurgent conditions were defined as self-reported difficulties accessing immediate care for issues such as fever, vomiting, headaches, sprains, minor burns, cuts, rashes, or other nonlife-threatening conditions. A multinomial logistic regression model examined the association between continuity of care (< 1 year, 1-< 2 years, ≥ 2 years, or no regular provider) and usual place of care, adjusting for demographic, socioeconomic, health, access, and provincial factors.

Among 41,060 seniors, most reported having continuity of care with a primary care physician for two years or more. Males and those reporting poorer health were more likely to use the ED for minor problems, whereas individuals with higher income or education more often sought care at a doctor's office. Longer continuity of care was associated with lower odds of ED use for minor problems, with consistent effects in both unadjusted (coef. = -0.251, P < 0.001) and adjusted models (coef. = -0.086, P = 0.083). Other determinants, including income, access to care, and province, also influenced care location.

Longer continuity with a primary care physician is associated with reduced ED use for minor health problems among seniors. These findings highlight the value of sustained patient-provider relationships in promoting appropriate care utilization and alleviating pressures on emergency departments.
