Three-year survival rates of pulmonary rehabilitation patients with chronic obstructive pulmonary disease.
A retrospective study analyzed medical and psychosocial factors associated with the three-year survival rates of clinically stable chronic obstructive pulmonary disease patients enrolled in a pulmonary rehabilitation program. The 69 percent three-year survival rate was similar to rates reported in previous studies. Neither continued cigarette smoking nor psychological variables were significantly associated with patient longevity. Discriminant analysis revealed that the combination of arterial O(2) and CO(2) tensions or its simple approximation (PaO(2) - PaCO(2)) was the best predictor of patient survival at three years.
