(In)Adequacy of Care • US NHANES Databases 1988 – 2002 • Glycemic control improved minimally • Blood pressure distribution unchanged • Improvements in lipids, ASA use, vaccinations • Why such slow improvement • Clinical inertia • Chronic illness • Lack of team approach • Reactive vs. proactive care
Control of CV Risk Factors in Diabetic Hypertensive Patients in Academic Medical Centers • A1C <7% • 27% • LDL <100 • 36% • BP <130/85 mmHg • 27% • Daily Aspirin (ASA) Use • 46% • BP, Lipids and A1C • 3% • BP, Lipids, A1C + ASA • 2% McFarlane SI. DiabetesCare 2002;25:718
Who Should Care for Diabetics? • 90 percent of diabetics receive care from generalist • Mortality rates and functional status no better for endocrinologists vs. FPs1 • Specialty clinics better at complying with eye exams and HgbA1C2 • JAMA 1995 Nov 8;274(18):1436-44 • Diabetes Care 1997 Apr;20(4):472-5
Glycemic Control • Does glycemic control matter? • Diabetes Complications and Control Trial (DCCT) • 1441 type 1 diabetics randomized into two groups • Conventional treatment (HgbA1C =9%) • Intensive treatment (HgbA1C = 7%) • Epidemiology of Diabetes and Complications (EDIC) • Continuation of DCCT in which groups were intensively managed • Previous intensive group had reduced macrovascular events Diabetes Complications and Control Trial (DCCT) N Engl J Med; 1993; 329: 977-986.
Effect of Tighter Glycemic Control on Progression of Retinopathy DCCT
United Kingdom Prospective Diabetes Study • Study summary – 10 years • Type 2 diabetics – convention vs. intense control • Glycemic control – 7.0 vs. 7.9 • Hypertension control – 144/82 vs. 154/87 • Glycemic control • metformin, sulfonylureas, and insulin • Hypertension • captopril, atenolol
UKPDS Blood Pressure Study:Tight vs. Less Tight Control • 1148 type 2 patients • BP lowered to avg. 144/82 (controls-154/87); 9 yr follow-up Endpoint Risk Reduction(%) P Value______ Any diabetes related endpoint 24 0.0046 Diabetes related deaths 32 0.019 Heart failure 56 0.0043 Stroke 44 0.013 Myocardial infarction 21 NS Microvascular disease 37 0.0092 UKPDS. BMJ. 317: 703-713. 1998.
Glycemic Difference in UKPDS • Difference obtained • Not as substantial as DCCT • Both groups worsened over time
Reduction in Type 2 DM EndpointsIntense Glycemic Control (UKPDS) • 12% reduction over 10 years • NNT = 19 at 10 years • Not nearly as impressive as BP outcomes
Reduced Microvascular End PointsIntense Glycemic Control (UKPDS) • Microvascular End Points reduced 25% in intense glycemic group • Renal failure • Death from renal failure • Retinal photocoagulation • Vitreous hemorrhage

ABCs Of Diabetes Management Diabetes Care 2007;30:S4-41
Recommendations for Adults with Diabetes Mellitus • Goals should be individualized • Certain populations (children, pregnant females and elderly) require special considerations • Set less intensive goals in patients with severe or frequent hypoglycemia • Most patients should target their HgbA1C to be less than 7%. The ACCORD trial has suggested more stringent targets aren’t beneficial and may be harmful
