Some low-acuity emergency department (ED) presentations are potentially avoidable with improved primary care access. The majority of ED patients (74.4%) in this study had a family physician, but the frequency of visits varied substantially. The variable frequency of patients' visits to these providers calls into question the validity of linkage assumptions. Several sociodemographic factors were associated with having a family physician, including female sex, being married/common law, race (Caucasian), being employed over the previous 12 months and having received a flu shot in the past year. These factors need to be explored further.
