Abstract
OBJECTIVE: To investigate the mortality of patients with Idiopathic Pulmonary Fibrosis (IPF) who undergo mechanical ventilation (MV) and non-invasive mechanical ventilation (NIMV) in the United States. METHODS: We performed a retrospective cohort study using data from the Nationwide Inpatient Sample, isolating patients with a diagnosis of IPF who underwent MV and NIMV between 2006 and 2012. RESULTS: We analyzed 55,208,382 hospitalizations and identified 17,770 patients with IPF, of whom 1703 received MV and 778 received NIMV. Those receiving MV had higher mortality (51.6 vs. 30.9%, p < 0.0001), were younger (66.3 years, SD 12.8 vs. 70.2 years, SD 12.9) and had longer hospital stays (13.3 days, IQR 16 vs. 6.5 days, IQR 7, p < 0.0001), compared to those receiving NIMV. The mortality of IPF patients treated with MV decreased from 58.4% in 2006 to 49.3% in 2012 (p = 0.03). There were 149 (8.7%) patients in the mechanical ventilation group who were also receiving home oxygen therapy. They experienced an overall mortality of 48.1%, which was not significantly different than patients who did not rely on home oxygen (p = 0.35). CONCLUSIONS: In a large national cohort, the in-hospital mortality of patients with IPF who are mechanically ventilated is approximately 50%.
