    27. DIGAMI Study Diabetes, Insulin Glucose Infusion in Acute Myocardial Infarction(1997) Acute MI With BG > 200 mg/dl Intensive Insulin Treatment IV Insulin For > 24 Hours Four Insulin Injections/Day For > 3 Months Reduced Risk of Mortality By: 28% Over 3.4 Years 51% in Those Not Previous Diagnosed

    28. Cardiovascular Risk Mortality After MI Reduced by Insulin Therapy in the DIGAMI Study Slide 6-11 BARRIERS TO INSULIN THERAPY Cardiovascular Risk Mortality After MI Reduced by Insulin Therapy in the DIGAMI Study Patients at high risk of cardiovascular disease are often thought to be inappropriate candidates for treatment with insulin because of the belief that hypoglycemia, hyperinsulinemia, or other metabolic effects of insulin might provoke or worsen the outcome of major cardiovascular events. This figure shows data from the Diabetes Mellitus Insulin-Glucose Infusion in Acute Myocardial Infarction (DIGAMI) trial. This Swedish trial studied the short-term and long-term effects of intensive insulin treatment of patients with diabetes who were enrolled in the trial at the time of a myocardial infarction. The subjects were immediately randomized to continued management according to the judgment of their physicians, or to intravenous infusion of insulin and glucose for 48 hours followed by a four-injection regimen subsequently for as long as 5 years. Other aspects of management of the infarction included treatment with b-blockers, angiotensin-converting enzyme inhibitors, fibrinolytic agents, and aspirin in high proportions of both groups. The rationale underlying the study was the old observation that, in animal experiments and studies of small numbers of humans, infarct size and outcome are improved by insulin-glucose infusion, in part because of suppression of otherwise elevated free fatty acid levels in plasma. The figure shows the cumulative total mortality rates in the whole population of 620 subjects randomized to the two treatments, as well as the rates for a predefined subgroup of subjects who were judged likely to survive the initial hospitalization and were not previously using insulin. The whole population showed an 11% actual and a 28% relative risk reduction with intensive insulin treatment after 5 years, and the subgroup showed a 15% actual and a 51% relative risk reduction. Most of the benefit was apparent in the first month of treatment and presumably was partly due to immediate intravenous infusion of insulin; however, the survival curves tended to separate further over time, suggesting an ongoing benefit from intensive treatment. This study suggests that insulin is an entirely appropriate treatment for patients with type 2 diabetes and high cardiovascular risk, especially at the time of myocardial infarction.

    29. ICU Survival 1548 Patients (mostly OHS pts.) All with BG >200 mg/dl Randomized into two groups All Maintained on IV insulin Conventional group (BG 180-200) Intensive group (BG 80-110) Conventional Group had 1.74 X mortality Study in belgium, interesting trial Study in belgium, interesting trial

    30. ICU IV Insulin Protocol (not DKA) If > 100 mg/dl, 2 U/h If > 200 mg/dl, 4 U/h If > 140 mg/dl, increase by 1 – 2 U/h If 121 to 140 mg/dl, increase by 0.5 – 1 U/h If 111 to 120 mg/dl, increase by 0.1 – 0.5 U/h If 81 to 110 mg/dl, no change If 61 to 80 mg/dl, change back to prior rate This is not for DKAThis is not for DKA

    33. Conclusion All hospital patients should have normal glucose

    34. Insulin The agent we have to control glucose

    35. Methods For Managing Hospitalized Persons with Diabetes Continuous Variable Rate IV Insulin Drip Major Surgery, NPO, Unstable, MI, DKA, Hyperglycemia, Steroids, Gastroparesis Basal / Bolus Therapy when eating Teach them insulin injections

    36. IV insulin protocol Not as intuitive as the Van den Berghe More agile in response to rate of change of blood sugars We do have a version of Van den Berghe available in the ICU

    37. Continuous Variable Rate IV Insulin Drip 25 units Regular Insulin into 250 cc NS (0.1 unit/cc) Starting Rate Units / hour = (BG – 60) x 0.02 BG is current Blood Glucose and 0.02 is the multiplier Check glucose every hour and adjust drip Adjust Multiplier to keep in desired glucose target range (100 to 140 mg/dl)

    38. Continuous Variable Rate IV Insulin Drip Adjust Multiplier (initially 0.02) to obtain glucose in target range 100 to 140 mg/dL If BG > 140 mg/dL, increase by 0.01 If BG < 100 mg/dL, decrease by 0.01 If BG 100 to 140 mg/dL, no change in Multiplier If BG is < 80 mg/dL, give D50 (one to three cc) Once eating, continue drip till 1 hour post SQ insulin This is lovely, elegant and simple. What it does is take into account the rate of change, the potential for This is lovely, elegant and simple. What it does is take into account the rate of change, the potential for

    39. Example Initial glucose of 200: drip starts at 2 units per hour Glucose drops to 90, decrease drip to 0.6 units per hour If glucose instead rose to 210, the drip increases to 4.5 units per hour

    43. Glargine vs NPH Insulin in Type 1 Diabetes Action Profiles by Glucose Clamp Based on euglycemic insulin clamp in normal subjectsBased on euglycemic insulin clamp in normal subjects

    44. Correction Bolus—Rule of 1500 Must determine how much glucose is lowered by 1 unit of short- or rapid-acting insulin This number is known as the correction factor (CF) Use the 1500 rule to estimate the CF CF = 1500 divided by the total daily dose (TDD) ex: if TDD = 30 units, then CF = 1500/30 = 50 meaning 1 unit will lower the BG ~50 mg/dl

    45. Correction Bolus Formula Example: Current BG: 220 mg/dl Ideal BG: 100 mg/dl Glucose Correction Factor: 50 mg/dl This the basis of the Baylor formula!! The baylor obviously fits no one! It works as an estimate for a total daily dose of 60 units, or about 260 pounds or 120 kilogramsThis the basis of the Baylor formula!! The baylor obviously fits no one! It works as an estimate for a total daily dose of 60 units, or about 260 pounds or 120 kilograms

    46. How to Initiate MDI Starting dose = 0.4 to 0.5 x weight in kilograms Bolus dose (aspart/lispro) = 20% of starting dose at each meal Basal dose (glargine/NPH) = 40% of starting dose given at bedtime or anytime Correction bolus = (BG - 100)/ Correction Factor (CF = 1500/total daily dose)

    47. How to Initiate MDI-example starting dose = 0.45 x wgt. in kg Wt is 110 kg; 0.45 x 110 = 50 units Basal dose (glargine) = 40% of starting dose at HS; 0.4 x 50 = 20 units at HS Bolus dose (aspart / lispro) = 20% of starting dose at each meal; 0.2 x 50 = 10 units ac (t.i.d.) Correction bolus = (BG - 100)/ CF, where CF = 1500/total daily dose; CF = 30 This is a starting point not gospel!! My friends in pulm/ccuThis is a starting point not gospel!! My friends in pulm/ccu

    48. Correction Bolus Formula Example: Current BG: 250 mg/dl Ideal BG: 100 mg/dl Glucose Correction Factor: 30 mg/dl

    49. Diabetes Plan What Can We Do For Patients Admitted To Hospital? Finger Stick BG ac q.i.d. on ALL Admissions Do Not Use Sliding Scale As Only Diabetes Management Check All Steroid Treated Patients Diagnose Diabetes FBG >126 mg/dl Any BG >200 mg/dl

    50. Diabetes Plan What Can We Do For Patients Admitted To Hospital? Get Diabetes Education Consult 449-5180 Do an A1C Instruct Patient in Monitoring and Recording See That Patient Has Meter on Discharge Decide on Case Specific Program for Discharge Arrange Early F/U with PCP Do Not Use Sliding Scale As Only Diabetes Management

    51. Diabetes at Hospital Conclusions Any BG >200 mg/dl Is Diabetes (Fasting >126 mg/dl) Most Diabetes Is Type 2 All DM patients Must Self-Monitor BGs and Record No BG >150 mg/dl Should Go Untreated Most Hospitalized DM Patients Should Be on Insulin IV Insulin is Most Effective, Efficient, Safest Rx in Acute Illness

    52. Diabetes at Hospital Conclusions 2 Type 2 Diabetes is Resistant to Insulin Reaction Do Not Hold Insulin for Normal BG A1C Values >7% Indicates Sub-optimal Care

    53. Diabetes at Hospital Conclusions 3 Discharge Plan For BG Control You Are the Link Between the Best Diabetes Care and the Patient Use Your Diabetes Resources Regional Diabetes Center 449-5180 Endocrinologists

    54. The Paradigm for the Millenium Hyperglycemia: A Mortal Sin A blood glucose over 200 in a hospitalized patient causes increased morbidity and mortality. In the 21st Century Neglecting a BG >200 May Be Malpractice

    55. Conclusion Intensive therapy is the best way to treat patients with diabetes
