Background: Idiopathic pulmonary fibrosis (IPF) is a devastating condition with a variable course. Not uncommonly, IPF patients are hospitalized for respiratory-related causes, including disease worsening. This study aimed to characterize the prevalence, and economic and health care burden of IPF. Methods: Retrospective insurance claims data collected yearly between January 1, 2009 and December 31, 2011, were used to determine prevalence and calculate all-cause and respiratory-related resource utilization and costs. Patients had at least one inpatient claim or two outpatient claims for IPF (ICD-9-CM code 516.3). Results for health care burden are reported for the 2011 cohort (similar findings in 2009-2010). Costs are reported in 2011 US dollars ($). Results: Patients with IPF had a mean age of 69.8-71.3 years. Overall prevalence for IPF was 28.8, 28.1 and 19.8 per 100,000 insured persons in 2009, 2010 and 2011. In each year, prevalence increased with age. In 2011, 37.7 % of patients were hospitalized at least once for any cause; 19.5 % for respiratory-related reasons. Also in 2011, the mean number of all-cause outpatient visits and respiratory-related office visits was 18.5 and 5.7 per patient, respectively. All-cause health care costs in 2011 were $ 59,379 per patient; 36.6 % of costs ($ 21,732) were respiratory related. Conclusions: The prevalence of IPF in this claims database increased with age, with a notable increase in those over 65 years. IPF is associated with a large economic and health care burden. Additional research is needed to determine how such burden might be reduced.
