    ObjectivesReadmissions after hospitalizations for acute exacerbation of chronic obstructive pulmonary disease (COPD) have a high socioeconomic burden. Comorbidities such as diabetes increase the risk for hospital readmissions, but the impact of diabetes on hospital outcomes remains unknown. The aim of this study was to evaluate the effect of complicated or uncomplicated diabetes on outcomes and health care costs related to admissions and readmissions in patients 35 years and older with an index admission for COPD.Study DesignThis was a retrospective longitudinal data analysis. We analyzed data from the Healthcare Cost and Utilization Project (HCUP) Nationwide Readmissions Database.MethodsWe analyzed the 2012-2015 HCUP Nationwide Readmissions Database and used multivariable weighted regression analyses to adjust for confounding factors. Individuals with any chronic pulmonary disease other than COPD were excluded.ResultsOf 1,728,931 patients hospitalized for COPD, 522,020 (30.2%) had a diagnosis of diabetes. Risk of all-cause 30-day readmission was higher among patients with complicated diabetes (adjusted odds ratio [OR], 1.15; 95% CI, 1.11-1.18) and uncomplicated diabetes (adjusted OR, 1.10; 95% CI, 1.08-1.12) compared with patients without diabetes. Diabetes was associated with longer length of stay, higher rates of hospital complications during index hospitalizations and 30-day readmissions, and a higher health care cost. Although diabetes was not associated with higher hospital mortality, routine hospital discharges were less common and the need for home health care upon discharge was higher among those with diabetes.ConclusionsPatients hospitalized for COPD and coexisting diabetes have worse clinical outcomes and higher 30-day readmissions compared with patients hospitalized for COPD without diabetes. Optimizing medical therapies and targeted interventions for both diseases is needed to alleviate disease burden to individuals and to society.
