If still unsuccessful, their designated surrogate will be contacted. Certain endpoints will be adjudicated by the same committee that was utilized by VADT. Endpoints that will be adjudicated will include: 1) cause of death; 2) reason for amputation; and 3) cardiac-related non-VA hospitalizations. Endpoints of interest in this study include: 1) mortality; 2) acute myocardial infarction requiring hospitalization; 3) stroke; 4) new onset congestive heart failure; 5) coronary revascularization; 6) amputation; 7) peripheral revascularization; 8) renal insufficiency; 9) severe visual impairment; and 10) self-reported health status (diabetes-related quality of life).
