Time-varying Readmission Diagnoses During 30 Days After Hospitalization for COPD Exacerbation.

ABSTRACT:

Objective

To investigate the longitudinal changes in principal readmission diagnoses within 30 days after hospitalization for acute exacerbation of chronic obstructive pulmonary disease (AECOPD).

Study setting

Medicare claims data, 2010-2012.

Study design

Retrospective cohort study.

Data collection methods

We identified AECOPD hospitalizations aged 65 years and above, and examined the principal 30-day readmission diagnoses (respiratory related, cardiac related, and other conditions). We also constructed Joinpoint regression models to test whether patients with each of the 3 major readmission conditions had a unique temporal pattern of readmission during the 30-day period.

Principal findings

Among 76,697 index hospitalizations with AECOPD, 14,090 (18.4%)
