Brief Reports High Users of Emergency Departments in Quebec Among Patients With Both

tors associated over time with high use of emergency departments by patients in Quebec who had schizo-phrenia and a co-occurring sub-stance use disorder. Methods: The cohort study included 2,921 pa-tients who received a diagnosis of schizophrenia in 2006 and had at least one emergency department visit during fiscal year 2006–2007. Generalized estimating equations were used to estimate predictors of high use of emergency depart-ments over time. Results: After adjustment for all covariates, pre-dictors of high use over time were as follows: living in either a university medical region (OR52.10) or ape-ripheral medical region (OR52.10), frequent hospitalization (OR51.16), and greater number of psychiatric (OR51.64) or physical comorbidities (OR51.23). Conclusions: Because high use of emergency departments is a strong indicator of poor care con-tinuity, identified associated factors could help develop and offer new programs to be deployed in the com-munity to better support these pa-tientswithgreaterneeds.
