Assessment of disease impact in patients with intermittent claudication: Discrepancy between health status and quality of life

Health status and quality of life represent different outcomes in patients with intermittent claudication. In addition to functional restrictions as measured in health status, quality of life also permits a personal evaluation of these restrictions. Objective functioning and subjective appraisal of functioning are complementary and not identical. Combining these measures should direct treatment in a way that meets patients' needs.
