Interstitial lung disease: retrospective study of the prognostic impact of acute exacerbations.

This study demonstrated that IPF, compared to PH and other fibrosing diseases, is associated with longer hospital stays, probably due to its progressive course despite the institution of corticosteroid therapy. As shown in previous studies, it was concluded that there is no difference in terms of mortality between IPF exacerbations and other forms of fibrosing lung disease.
