Factors Associated With Diabetes Care Quality Among Patients With Schizophrenia in Ontario, Canada

The authors investigated demographic, clinical, and service-utilization factors that affected the quality of diabetes care among patients with schizophrenia.This was a retrospective cohort study of adults with schizophrenia and diabetes (N=26,259) in Ontario, Canada. Quality of care was based on receipt of three guideline-concordant diabetes care procedures between 2011 and 2013. A cumulative logit regression model was used to determine characteristics associated with optimal testing.Factors associated with optimal diabetes testing included more frequent outpatient psychiatrist visits (odds ratio [OR]=1.28, 95% confidence interval [CI]=1.20-1.37) and primary care visits for nonmental health reasons (OR=2.10, 95% CI=1.85-2.39). High-frequency primary care visits for mental health reasons, any hospitalizations, and emergency visits for mental health reasons were associated with lower odds of testing.Diabetes quality of care may be contingent on receipt of medically focused primary care, psychiatric stability, and receipt of specialist psychiatric care.
