Rationale: Progression of idiopathic pulmonary fibrosis (IPF) is accompanied by worsening of symptoms, exercise capacity, and health-related quality of life. However, the utility of patient-reported outcomes as predictors of mortality remains uncertain.Objectives: To assess whether patient-reported outcomes are independently associated with mortality beyond clinical risk factors in patients with IPF.Methods: Data from the observational IPF Prospective Outcomes Registry were used to examine associations between patient-reported outcomes at enrollment and the composite outcome of death or lung transplant in the following year. Associations were examined using univariable models and models adjusted for age and clinical variables that have been associated with death or lung transplant in patients with IPF in this cohort (oxygen use, forced vital capacity % predicted, and diffusing capacity of the lungs for carbon monoxide % predicted at enrollment).Results: Among 662 patients, 45 died and 12 underwent lung transplant over 1 year. In the model adjusted for age and clinical variables that were associated with death or lung transplant, worse scores on the St. George's Respiratory Questionnaire (SGRQ) total score (hazard ratio [HR], 1.22 [95% confidence interval (CI), 1.01-1.48] per 10-point increase), SGRQ activity score (HR, 1.25 [95% CI, 1.02-1.54] per 10-point increase) and SGRQ symptoms score (HR, 1.17 [95% CI, 1.01-1.36] per 10-point increase) were associated with death or lung transplant over 1 year.Conclusions: Patient-reported outcomes that assess symptoms and physical activity are independently associated with mortality in patients with IPF.
