Tracking dyspnea up to supplemental oxygen prescription among patients with pulmonary fibrosis.

ABSTRACT:

Background

Dyspnea is the hallmark symptom of pulmonary fibrosis. Supplemental oxygen (O₂) is prescribed to many patients with pulmonary fibrosis in hopes of alleviating dyspnea and improving physical functioning. We used response data from the University of California San Diego Shortness of Breath Questionnaire (UCSD) which was administered monthly in the context of a longitudinal, observational study to plot a rich trajectory for dyspnea over time in patients with pulmonary fibrosis. We used other data from that study to identify clinical predictors of being prescribed O₂ and to provide additional information for how UCSD scores could be used for clinical purposes.

Methods

We used linear mixed-effects models and multivariate Cox proportional hazards t
