OBJECTIVES To examine the relationship between family immigrant status and unscheduled 7-day revisits to the emergency department (ED) and to test this relationship within subgroups of immigrants by visa class (family, economic, refugee), native tongue on landing in Canada, and region of origin. STUDY DESIGN Population-based cohort study that used multiple linked health administrative and demographic datasets of landed immigrant and nonimmigrant children (<18 years) in urban Ontario who visited an ED and were discharged between April 2003 and March 2010. Logistic regression was used to model the odds of 7-day ED revisits with family immigrant status, with adjustment for patient and ED characteristics. RESULTS Of 3,322,901 initial visits to the ED, 249,648 (7.5%) resulted in a 7-day revisit. There was no significant association of immigrant status with either ED revisits or poor revisit outcomes (greater acuity visit or need for admission) in the adjusted models. Within immigrants, the odds of revisit were not associated with immigrant classes or region of origin; however, immigrants whose native tongue was not English or French had a slightly greater odds of revisiting the ED (aOR 1.05; 95% CI 1.01, 1.09). Significant predictors of revisits included younger age, greater triage acuity score, greater predilection for using an ED, daytime shifts, and greater deprivation index. CONCLUSIONS Immigrant children are not more likely to have short-term revisits to the ED, but there may be barriers to care related to language fluency that need to be addressed. These findings may be relevant for improving translation services in EDs.
