Per uWorld answer: For example, FEV1 only loosely correlates with survival. Of far greater significance is functional status: how patients adapt to their diminished lung function.
Mortality in chronic obstructive pulmonary disease is best predicted by integrative measures such as global functional impairment, multidimensional risk indices—such as BODE (low BMI, very severe Obstruction, disabling Dyspnea, and low Exercise capacity—and presence of significant nonpulmonary (mainly cardiovascular) comorbidities.
