Objectives
Narrative objectives1
We retrospectively analyzed 76 patients (49 with idiopathic interstitial pneumonia and 27 with interstitial pneumonia associated with collagen vascular disease) with clinically diagnosed interstitial pneumonia who received LTOT to investigate the prognosis from the initiation of LTOT and clarify prognostic factors.

Key inclusion criteria
Patients with clinically diagnosed idioathic interstitial pneumonia or interstitial pneumonia associated with collagen vascular disease who initiated to receive long-term oxygen therapy in Osaka University Hospital from January 1999 to December 2012 were searched. The diagnosis of interstitial pneumonia was determined based on laboratory data, pulmonary function test, physical examination, and high resolution computed tomography findings. The diagnosis of collagen vascular disease was according to established guideline. Long-term oxygen therapy was initiated if PaO2 of arterial blood gas at rest under room air was below 60 mmHg; or if SpO2 on exertion breathing room air was below 90 accompanied by significant dyspnea.
Key exclusion criteria
Exclusion criteria were as follows: subjects with interstitial pneumonia suspected to be secondary to environmental exposure or drug toxicities; subjects with severe organ disease or active invasive cancer at the initiation of long-term oxygen therapy.
