Quality of life is not a question of fashion but rather a new percepti
on of the effects of health care. Unfortunately, currently developed m
eans of assessing health status only rarely englobe quality of life as
sessment and when they do, still need much improvement. Modelization i
s a difficult task and requires a long scientific approach. In order t
o achieve the goal of reliable quality of life assessment, the differe
nt professional colleges should work together with methodologists to i
dentify assessment criteria and include them in future clinical resear
ch protocols.
