Diagnosis of the different IP subtypes in 3 steps
Interstitial lung diseases (n = 88) Step 1: histology alone (pattern) Step 2: histology + clinical information Step 3: interdisciplinary case evaluation
Idiopathic interstitial pneumonia or pattern* 85 77 63
  IPF/Usual interstitial pneumonia (UIP) 31 29 27
  Non specific interstitial pneumonia (NSIP) 21 20 14
  Respiratory bronchiolitis with ILD (RBILD) 14 10 6
  Desquamative interstitial pneumonia (DIP) 3 3 3
  Cryptogenic organizing pneumonia (COP) 13 12 10
  Acute interstitial pneumonia (AIP) 1 1 0
  Lymphocytic interstitial pneumonia (LIP) 3 3 3
Non idiopathic interstitial pneumonia 3 11 25
  Hypersensitivity pneumonitis (HP) 0 3 10
  Langerhans cell histiocytosis (LCH) 3 7 7
  IP of other known causes or associations 0 1 8
Correctness of diagnosis (total) 67%* 87%* 100%

*p < 0.05 vs interdisciplinary case evaluation (exact Fisher test).
