Supplemental Oxygen in Pulmonary Fibrosis

Completed

Brief Summary: To enhance understanding of supplemental oxygen-its utility in and adoption by patients with pulmonary fibrosis-by examining how patients perceive it and by determining how perceptions and patient-centered outcome measures change from before to after supplemental oxygen is prescribed.

Detailed Description: The investigators aim to recruit patients with PF to participate in interviews and/or a one-year study of supplemental oxygen (O2). In the one-year study, the investigators will collect data before and for one year after PF patients are prescribed daily-use supplemental oxygen and compare outcomes, including shortness of breath, quality of life, fatigue, cough, and day-to-day functioning before and after O2.

Primary Outcome Measures

Name	Time	Method
Change in University of California San Diego Shortness of Breath Questionnaire From Immediately Prior to One Month After Starting Daily-use Supplemental Oxygen	UCSD SOB score at one month after being prescribed supplemental O2	The University of California San Diego Shortness of Breath Questionnaire (or UCSD SOB) is a tool that measures shortness of breath using 24 items, each with response options ranging from 0 to 5, corresponding to "None at all" and "Maximally or unable to do because of breathlessness." Thus, scores for the UCSD SOB range from 0 to 120, with higher scores indicating greater shortness of breath.

Secondary Outcome Measures

Name	Time	Method
Fatigue Severity Scale	One month after daily-use supplemental oxygen implementation	The Fatigue Severity Scale is a 9-item questionnaire, scored from 9-63, with higher scores indicating more severe fatigue.
Change in Physical Component Summary (PCS) Score From the Medical Outcomes Study Short-Form, 36-item Questionnaire (SF-36).	One month after daily-use supplemental oxygen implementation	The PCS of the SF-36 assesses a domain of quality of life. Its scores range from 0-100, with higher scores indicating better quality of life on this domain.
