Correlation of psychophysiologic variables with vocational rehabilitation outcome in patients with chronic obstructive pulmonary disease

I Kass, JE Dyksterhuis, H Rubin and KD Patil

Despite the magnitude of the public health problem presented by respiratory diseases, there have been few studies concerned with vocational rehabilitation (VR) potential of patients with chronic obstructive pulmonary disease (COPD). Certain physiologic variables which show a high degree of relationship to VR success are identified. The three independent variables which most highly correlate with the VR potential of patients with COPD are the percentages predicted for the first-second forced expiratory volume (FEV(1.0)), forced expiratory flow between 25 and 75 percent of the forced vital capacity (FEF(25-75 percent)), and maximum voluntary ventilation (MVV). The mean "cutting" percentages for inclusion in VR programs were 50, 27, and 40, respectively. The emotional variables studied do not differentiate potential VR success or failure as clearly as the physiologic factors. The criteria set forth not only can be used by rehabilitation workers but could serve as a basis for future demonstration studies.
