Scussel-Lonzetti et al reported factors associated with mortality for a patient with systemic sclerosis. These can help to identify a patient who may benefit from more aggressive management. The authors are from Centre Hospitalier de l'Universite de Montreal in Quebec.
Patient selection: systemic sclerosis
Parameters:
(1) trunk involvement
(2) age in years at diagnosis
(3) DLco as percent of predicted
(4) erythrocyte sedimentation rate (ESR) in mm/h
(5) hemoglobin in g/dL

total score =
= SUM(points for all of the parameters)
Interpretation:
• minimum score: 0
• maximum score: 5
• The higher the score the greater the mortality.
