Impact of lung function on exacerbations, health care utilization, and costs among patients with COPD.

ABSTRACT:

Objective

To evaluate the impact of lung function, measured as forced expiratory volume in 1 second (FEV1) % predicted, on health care resource utilization and costs among patients with COPD in a real-world US managed-care population.

Methods

This observational retrospective cohort study utilized administrative claim data augmented with medical record data. The study population consisted of patients with one or more medical claims for pre- and postbronchodilator spirometry during the intake period (July 1, 2012 to June 30, 2013). The index date was the date of the earliest medical claim for pre- and postbronchodilator spirometry. Spirometry results were abstracted from patients' medical records. Patients were divided into two groups (low FEV1% predicted [,50%] and high FEV1%
