- W2321815482 abstract "Idiopathic pulmonary fibrosis (IPF) is a rare and fatal restrictive respiratory disease under the idiopathic lung disease (ILD) class. IPF is a form of chronic, progressive fibrosing interstitial pneumonia and has more scarring, less inflammation, and poorer prognosis than most other ILD forms. Exacerbation of IPF is rapid, with unpredictable deterioration of lung function, and is associated with short-term mortality. The American Thoracic Society (ATS) evidence-based guidelines for diagnosis and management of IPF reports that the incidence of acute exacerbations is between 5%-10%. Limited real-world evidence has been identified in the United States that assesses patterns of hospitalization, exacerbation of IPF, and the associated economic burden.To (a) characterize patients newly diagnosed with IPF and (b) examine incidence rates and costs of all-cause hospitalizations, IPF-related hospitalizations, and exacerbations.A retrospective analysis was performed with a national commercial claims database from calendar years 2006 to 2011. Newly diagnosed IPF patients were identified with either ≥ 2 claims for idiopathic fibrosing alveolitis (IFA) or ≥ 1 claim for IFA and ≥ 1 claim for postinflammatory pulmonary fibrosis and a lung biopsy or thoracic high-resolution computed tomography within 90 days of the first claim for IFA (index date). IPF-related hospitalizations and possible IPF exacerbations were defined based on diagnoses recorded on event claims. Frequency, incidence rate, duration of events, and associated costs from the third-party payer's perspective were estimated.Among 1,735 identified IPF patients, 38.6% had at least 1 all-cause hospitalization; 10.8% had IPF-related hospitalizations; 4.6% had suspected IPF exacerbations leading to hospitalization; and 72.1% had suspected IPF exacerbations leading to urgent outpatient visits during the 1-year post-index period. Incident rates for these 4 events were 83 (95% CI = 79-88), 17 (95% CI = 14-19), 7 (95% CI = 6-9), and 277 (95% CI = 269-286) per 100 person-years, respectively. Average costs per event were $13,987 (SD = $41,988), $16,812 (SD = $66,399), $14,731 (SD = $85,468), and $444 (SD = $1,481), respectively.Hospitalizations and possible exacerbations among patients with IPF were costly. Appropriate management of IPF needs to be considered to help slow IPF disease progression.Boehringer Ingelheim Pharmaceuticals, Inc. (BIPI) provided funding for this study. Yu and Devercelli are currently salaried employees of BIPI.
