Objectives — To evaluate the impact of comorbidity on diabetes care quality and diabetes-related hospitalizations and to examine whether associations between the likelihood of diabetes-related hospitalizations and compliance with diabetes testing are modified by type of comorbidity.
Methods — A population-based cohort study of 861 354 adults with diabetes was conducted in Ontario, Canada. The diabetes cohort was categorized into 4 groups defined by their comorbidity statuses: no comorbidity, diabetes-concordant only, diabetes-discordant only, and both concordant and discordant. Outcome variables were defined as having had at least 1 hospitalization for diabetes-related short- or long-term complications between 2009 and 2011. Diabetes-care quality measures included testing for glycated hemoglobin (A1C) and low-density lipoprotein-cholesterol levels and eye examinations between 2007 and 2009. Multivariable logistic regression models were performed to examine the associations between diabetes testing and diabetes-related hospitalizations and the modifying role of comorbidity type.
Results — Compliance with all 3 monitoring tests by patients with diabetes had a strong positive impact on reducing hospitalizations for diabetes-related long-term complications, especially in patients with diabetes-concordant conditions. The highest levels of adherence to all 3 diabetes monitoring tests were observed in patients with diabetes-concordant conditions only and in patients with diabetes-discordant conditions. The highest odds of hospitalizations for diabetes-related short-term complications were observed in patients having both discordant and concordant conditions.
Conclusions — Meeting diabetes testing goals has the potential to reduce hospitalizations for diabetes-related complications; however, this depends on types of coexisting chronic conditions and diabetes-related complications in patients with diabetes.
