Background: Real-world data regarding health-care resource use (HCRU) and costs of idiopathic pulmonary fibrosis (IPF) are scarce. In France, at the time of the study, pirfenidone and nintedanib were reimbursed for documented IPF only, with similar reimbursement criteria with regard to disease characteristics, prescription through a dedicated form, and IPF diagnosis established in a multidisciplinary setting. The objective of this study was to evaluate costs related to HCRU in patients newly treated with pirfenidone or nintedanib in 2015-2016, in France, using the exhaustive claims data of the French National Health System.Methods: Patients aged <50 years or who had pulmonary fibrosis secondary to an identified cause were excluded. HCRU-related costs up to 31 December 2017 were compared using generalized linear models adjusted for age, sex, year of treatment initiation, time to treatment initiation and proxies of disease severity identified during a pre-treatment period.Results: During the study period, a treatment with pirfenidone or nintedanib was newly initiated in 804 and 509 patients, respectively. No difference was found between groups for age, sex, time to treatment initiation, Charlson comorbidity score, and number of hospitalisations or medical visits prior to treatment initiation. As compared to pirfenidone, nintedanib was associated with higher costs for medications (1.2; 95% CI, 1.1-1.3) and medical visits (1.3; 95% CI, 1.2-1.4), as well as a higher global cost (1.1; 95% CI, 1.0-1.2). The costs of medical procedures, hospitalizations and indirect HCRU did not statistically differ between the two cohorts.Conclusions: This observational study identified potential differences in HCRU-related costs under newly pre-scribed antifibrotic drugs, deserving further explorations.(c) 2022 SPLF and Elsevier Masson SAS.

Abstract
Background: Real-world data regarding health-care resource use (HCRU) and costs of idiopathic pulmonary fibrosis (IPF) are scarce. In France, at the time of the study, pirfenidone and nintedanib were reimbursed for documented IPF only, with similar reimbursement criteria with regard to disease characteristics, prescription through a dedicated form, and IPF diagnosis established in a multidisciplinary setting. The objective of this study was to evaluate costs related to HCRU in patients newly treated with pirfenidone or nintedanib in 2015-2016, in France, using the exhaustive claims data of the French National Health System.Methods: Patients aged <50 years or who had pulmonary fibrosis secondary to an identified cause were excluded. HCRU-related costs up to 31 December 2017 were compared using generalized linear models adjusted for age, sex, year of treatment initiation, time to treatment initiation and proxies of disease severity identified during a pre-treatment period.Results: During the study period, a treatment with pirfenidone or nintedanib was newly initiated in 804 and 509 patients, respectively. No difference was found between groups for age, sex, time to treatment initiation, Charlson comorbidity score, and number of hospitalisations or medical visits prior to treatment initiation. As compared to pirfenidone, nintedanib was associated with higher costs for medications (1.2; 95% CI, 1.1-1.3) and medical visits (1.3; 95% CI, 1.2-1.4), as well as a higher global cost (1.1; 95% CI, 1.0-1.2). The costs of medical procedures, hospitalizations and indirect HCRU did not statistically differ between the two cohorts.Conclusions: This observational study identified potential differences in HCRU-related costs under newly pre-scribed antifibrotic drugs, deserving further explorations.(c) 2022 SPLF and Elsevier Masson SAS.
