Traditionally, to assess the value of an intervention, physicians have used objective, “physician-centered” outcome measures. These measures would include such endpoints as survival of cancer patients, recurrences after hernia repair, increased blood flow after vascular bypass, incidence of stroke after carotid artery surgery, and the like. Although such measures are valuable, they do not tell the whole story in the patient’s experience. In some respects, they are surrogates for the true endpoint – is the patient feeling better and can he or she function and enjoy life? It is this aspect of measuring patient-perceived functional improvements that the field of quality of life research developed (Testa and Simonson, N Engl J Med 334:835–40, 1996).
