Unmodifiable Risk Factors May Drive COPD Readmission

National efforts are underway to reduce 30-day for chronic obstructive pulmonary disease (); however, new research suggests that readmissions may be related to risk factors that cannot be modified, including advanced disease and psychosocial factors.

Researchers from the University of Texas Medical Branch in Galveston performed a retrospective chart review of all patients with primary discharge diagnosis of COPD. Of the 160 patients admitted for a total of 193 hospitalizations, 30 patients were readmitted within 30 days. Patients who were readmitted were more likely to be black, had , , history of , and were using supplemental oxygen. There was no difference in baseline medication use, length of stay, or serum bicarbonate values, and whether or not the patient had a follow-up postdischarge. In a multivariate analysis, odds of 30-day readmission was 2.56 in patients using supplemental oxygen, and 2.17 in patients with .

Researchers conclude that 30-day readmission in patients with COPD was related to advanced disease and psychosocial factors that are unlikely to be modifiable.

This study was presented during CHEST 2012, the annual meeting of the , held October 20 – 25, in Atlanta, Georgia.
