ABSTRACT
OBJECTIVE: For patients who belonged to physician rosters at a family medicine practice in the core of Calgary, Canada, we compared primary care utilization for those who were stably housed and those experiencing homelessness. METHODS: This retrospective chart review accessed electronic medical record data for rostered patients who visited their family physician between July 1, 2015 and August 31, 2016. We assessed the association between homelessness status (defined as having been sheltered in overnight shelters and/or emergency/provisional housing during the study period) and the rate of visits to primary care (defined as the count of visits associated with a patient accounting for the length of the patient's relationship with their family physician) using multivariate negative binomial regression. RESULTS: We analyzed 1013 patients belonging to three family physician rosters, of whom 112 experienced homelessness during the study period (11.1%). The mean number of visits for patients who experienced homelessness was 9.6 (SD 10.5), compared to 4.2 (SD 3.6) visits for stably housed patients (p < 0.0001). The rate of accessing primary care for patients experiencing homelessness was 2.02 times greater than the rate for stably housed individuals (rate ratio [RR] 2.02, 95% confidence interval [95% CI] 1.74-2.35; p < 0.0001). CONCLUSION: In the context of an inner-city primary care clinic in Calgary, Canada, homelessness status is associated with an increased rate of visits to primary care. This work has implications for public health and health systems decision-makers involved in developing equitable health policy, as well as for frontline care providers who serve this vulnerable population.
