ABSTRACT

Introduction

This study quantifies costs associated with comorbid conditions among adults diagnosed with chronic obstructive pulmonary disease (COPD) who experience acute exacerbations (AECOPD) needing inpatient hospitalization.

Methods

This retrospective cohort study used 2006–2015 IQVIA PharMetrics® Plus data, a health plan claims database. Patients aged 40–64 years, with AECOPD, defined as an inpatient hospitalization for a COPD-related diagnosis were included. The impact of comorbidities on AECOPD costs (costs of the COPD-related inpatient stay plus healthcare services used 30 days post-discharge) was determined using multivariable regression. The models adjusted for clinical complications, previous utilization, age, sex, region, year, length of hospitalization, and season of admission.

Results

Among these COPD patients, 89.5% had at least 1 comorbidity. The mean cost for AECOPD was 2015 US $19,687 (SD: 27,035, median: 11,539). Congestive heart failure, lipid disorders, cancer, and presence of any of the 10 most frequent comorbidities were associated with $1,921 (95% confidence interval (CI): 977–2,866), $1,619 (95% CI: 967–2,272), $8,347 (95% CI: 7,236–9,458), and $4,433 (95% CI: 3,598–5,268) higher costs, respectively than corresponding individuals without these comorbid conditions. Patients with depressive disorders were associated with $1,592 (95% CI: 828–2,355) lower costs compared to those without depressive disorders.

Conclusion

COPD comorbidity imposes a significant economic burden on AECOPD.
