Abstract

Abstract: Background: This study examined the association between different types of comorbidities and the quality of diabetes care, health‐related quality of life (HRQoL), and total health care expenditure. Methods: Adult patients with diabetes were identified from the 2011 to 2013 Medical Expenditure Panel Survey, a nationally representative survey of the civilian non‐institutionalized US population. Twenty different chronic conditions were captured and categorized as: (i) diabetes only; (ii) diabetes plus concordant (diabetes‐related) comorbidity only; and (iii) diabetes plus one or more discordant (non‐diabetes‐related) comorbidities. Disease burden outcomes included the process of diabetes care (eye and foot examinations, HbA1c and cholesterol tests, influenza vaccination), HRQoL, and total health care expenditure. Multivariable models were used to examine associations between the type of comorbidity and outcomes. Results: A sample of 8292 patients with diabetes was identified, of which 11.4% had diabetes only, 40.5% had concordant comorbidity only, and 48.1% reported one or more discordant comorbidities. Patients with diabetes and either type of comorbidity received better quality of diabetes care than those without a comorbidity. However, patients with discordant comorbidity showed significantly lower HRQoL measures and higher health care expenditure than those with concordant comorbidity. Adjusted total mean annual expenditure was US$4891, $6326, and $9210 for those with diabetes only and those with diabetes with one concordant or one discordant comorbidity, respectively. Conclusions: Higher disease burden in patients with diabetes was associated with discordant rather than concordant comorbidity. Future interventional studies evaluating patient‐centered care models addressing different types of comorbidity are necessary to better manage these complex patients. Abstract : Highlights Among all patients with diabetes, 88.6% have certain comorbid conditions. Approximately 40.5% have diabetes‐associated conditions (concordant comorbidity) and 48.1% have conditions not related to diabetes (discordant comorbidity). Patients with diabetes only spent less money on medical‐related expenses, but received worse diabetes care than patients with comorbid conditions. Higher disease burden in terms of medical expenditure and health‐related quality of life in patients with diabetes was associated more with discordant than concordant comorbidity.
