  2. Outline • Introduction. • Diabetes prevalence & burden. • Metabolic goals to reduce illness. • Benchmarks and recognition programs. • Economic impact of improving diabetes control. • Model for promoting intensive insulin therapy at the primary-care level. • Basal/bolus insulin therapy & patient education. II Workshop on Quality of Diabetes Care, Miami, May 2003

  3. Purpose of Optimizing Care • Reduce burden of illness. • Microvascular and macrovascular complications. • Acute complications (hypoglycemia, hyperglycemia, DKA). • Enhance quality of life. • Reduce fiscal burden. II Workshop on Quality of Diabetes Care, Miami, May 2003

  26. Impact of Comprehensive Diabetes Management Program • DTCA NetCare management program • Population based approach. • Multidisciplinary team works with plan physicians and patients to effect behavioral change. • Stratify/profile both patients & physicians to target level of support. • Seven MCO plans with 360,000 covered lives and 7,000 patients with diabetes. • Evaluate short-term impact. • Care coordination. • Guideline adherence.

  37. Success of Program Depends on • Getting primary-care physicians (PCPs) to attend the program. • Inviting key diabetes educators. • May need to set up additional training to certify competency in basal/bolus therapy. • Facilitating network opportunities between PCPs and educators. • Evaluate impact of program. • Pre- & post-program questionnaires. II Workshop on Quality of Diabetes Care, Miami, May 2003

  38. The End II Workshop on Quality of Diabetes Care, Miami, May 2003

  39. Calculating Insulin Ratio & Doses • Calculate total daily insulin dose (TDI) • Based on current insulin doses • Based on weight in kg (weight x 0.5 u/kg/day) • TDI is approximately ½ basal and ½ bolus replacement • Example: A 80 kg patient would require ~ 40 units of insulin per day, of which 20 units are for basal replacement and 20 units to cover meal carbohydrates II Workshop on Quality of Diabetes Care, Miami, May 2003

  40. Calculating Insulin Ratio & Doses • Calculate corrective ratio (supplemental insulin) • For Lispro or Aspart use 1800  TDI = fall in glucose (mg/dl) per 1 unit of insulin • For Regular insulin use 1500  TDI = fall in glucose (mg/dl) per 1 unit of insulin • Example: A patient requiring 40 units of insulin per day would expect a 45 mg/dl drop per unit of Lispro/Aspart insulin II Workshop on Quality of Diabetes Care, Miami, May 2003

  41. Basal/Bolus Insulin Prescription • Basal insulin replacement • Insulin Glargine 20 units at bedtime • Prandial insulin replacement • 7 units Lispro or Aspart before meals • Correction (supplemental) insulin • 1 unit per 45 mg/dl above target • Pre-meal target: 120 mg/dl II Workshop on Quality of Diabetes Care, Miami, May 2003
