Recently, the International Working Group in AE-IPF revised the definition and diagnostic criteria for AE-IPF. AE-IPF is defined as an acute, clinically significant respiratory deterioration characterized by evidence of new widespread alveolar abnormality. Acute worsening of development of dyspnea typically with less than 1-month duration is among the diagnostic criteria.

Although signs of heart failure may be present in an acute exacerbation, it should not fully explain the severity of the respiratory deterioration.

It is no longer necessary to demonstrate the absence of an infectious cause by endotracheal aspirate or bronchoalveolar lavage. A CT scan with new bilateral ground-glass opacity and/or consolidation superimposed on a background with a usual interstitial pneumonia pattern is also required for a diagnosis of AE-IPF.
