Primary Outcomes: The primary outcomes are: 1) prevalence of undiagnosed non-insulin-dependent diabetes mellitus (NIDDM); 2) HRQoL as measured by SF-36; 3) glycemic control as measured by HbA1C; and 4) calculation of the 3-year direct utilization-related cost, from the perspective of the VA, associated with early diagnosis of DM, and comparison of this to the 3-year direct utilization-related cost for veterans who are screened for diabetes but do not have diabetes.
