So What is Diabetes Care? Controlling complications - blood sugar - blood pressure - lipids Losing weight! Becoming more active If you smoke, STOP! Guidelines – the Short Form 1. BG, BP, Lipid control 2. Sceening: eyes, kidneys, feet 3. ASA use 4. Smoking cessation Monitoring Goals in a Nutshell • • • • • • • A1c (<7=goal, >8=‘action required’) BP control (<130/80) Lipids (1: LDL<100, 2: HDL>40, 3: TG<200) Retinal exams – yearly Nephropathy screening (Microalbumin) - yearly Foot screening – yearly and as indicated ASA therapy – basically, if over 30 and not contraindicated • Smoking Cessation Lifetime Microvascular Events in Type 2 Diabetes HbA1c 7.2% Percent Change Blindness HbA1c 10% 19% 5% -72 Renal failure 17% 2% -87 Symptomatic Neuropathy Amputation 31% 10% -68 15% 5% -67 Eastman, RC et al Model of Complications of NIDDM, Diabetes Care, May 1997, 20(5), 735-744. Hypoglycemia • The only diabetic emergency you may routinely see on the farm • Signs and symptoms: “he ain’t actin’ right”, agitation, sweats, shakes, heart rate, confusion • Cause: blood sugar too low • Cure: EAT SOMETHING RIGHT NOW! Diabetes: What To Do? Prevention - prevent obesity - in those already overweight, prevent diabetes Decrease the cost of existing disease - decrease complications - improve the quality of care But How Do We Do It??? System of care reforms – a new approach to this disease is needed Education - for patients and providers Population strategies - Children & Mothers - Schools - Regulatory efforts Research - Basic - Translational The Big Picture The burden of both type 2 diabetes and obesity is rapidly increasing, and shows no sign of stopping. If our society does not change this, diabetes alone will bankrupt our medical system. We can prevent most of the misery and cost, but we aren’t. Diabetes is highly preventable; for those with diabetes, its complications are highly preventable. Systematic approaches (e.g. – guidelines, disease management, …) to diabetes FAR exceed the results of traditional care and enhance provider effectiveness.
