The Effects of a Comprehensive Care Management Program on Readmission Rates After Acute Exacerbation of COPD at a Community-Based Academic Hospital.

Acute exacerbation of chronic obstructive pulmonary disease (AECOPD) is one of the leading causes of hospitalization in the United States. Prior investigations suggest clinical and physiological parameters are important determinants for AECOPD readmissions. Strategies aimed at addressing these factors have not resulted in a major reduction of readmissions. We compared patients readmitted after an index AECOPD admission with non-readmitted patients. Patients' age, gender, body mass index, comorbidities (obstructive sleep apnea, chronic hypercapnia, congestive heart failure, lung cancer, pulmonary arterial hypertension, pneumonia, interstitial lung disease, atrial fibrillation, musculoskeletal disorders, cognitive disorders, and anxiety disorders), substance abuse and smoking status were assessed. Some 272 patients were included: 20 patients were readmitted within 30 days of their index hospitalization; 252 patients were not readmitted within 30 days of their index admission. Readmitted patients were significantly more likely to have pneumonia than non-readmitted patients (30.0% versus 13.1%, <0.05). No statistically significant difference was seen with respect to other clinical comorbidities. Patients readmitted within 30 days were significantly more likely than non-readmitted patients to have safety issues at home (80.0% versus. 39.3%, <0.001), anxiety (60.0% versus 29.8%, <0.01), and lack of transportation (35.0% versus 15.5%, <0.05). Implementation of a comprehensive care management program (CCMP) was associated with a reduction in readmissions from 21.5% to 13.6% (<0.01, 95% confidence interval [CI] 2.08-12.45). A CCMP can reduce readmissions through attention to social variables, optimization of in-hospital care, improved coordination of pre- and post-discharge, a system to better identify problems after discharge, and an office setup that accommodates same-day visits.
