SADL Model of Morisset et al for Scleroderma-Related Interstitial Lung Disease

Description

Morisset et al developed a score for predicting mortality for a patient with scleroderma-related interstitial lung disease (ILD). This can help to identify a patient who may benefit from more aggressive management. The authors are from the University of California San Francisco, Mayo Clinic, and the University of Colorado.


Patient selection: scleroderma-related interstitial lung disease (Scl-ILD)

 

Outcome: 3-year all-cause mortality

 

Parameters:

(1) ever smoked (S)

(2) age in years (A)

(3) DLco as percent of predicted (DL)
