INSULIN PUMP THERAPY 2011

HISTORY OF DIABETES ► 1550 BC first described in an Egyptian manuscript as “the passing of too much urine”. ► 2 nd Century Greek Physician Aretaeus first used the word Diabetes derived from the Greek meaning “siphon” or “to go through” referring to urinary frequency. ► 17 th Century English Anatomist and Physician first used the word Mellitus from the Latin meaning “honey”. ► insulin was discovered by Fredrick Banting and Charles Best (Macleod and Collip).

DIABETES TODAY ► Worldwide 346 million people with DM. ► >80% DM deaths occur in low and middle income countries. ► Diabetes affects ~27million people in the U.S. or 8.7% of the population. ► Leading cause of renal failure, new cases of blindness, non-traumatic amputations in adults, and one of the major contributing factors of heart disease and strokes. ► In 2010 it is estimated that health spending associated with diabetes and prediabetes is about 194 billion dollars. The cost is projected to rise to 500 billion dollars by ► CDC projects that by 2050, up to 1 in 3 Americans may have DM.

DIABETES TODAY ► In 2010, there were approximately 5800 board certified endocrinologists in the U.S. of which an estimated 2000 of those were involved in research or academics. ► The number of endocrinology fellowships have decreased from 140 in 1987 to 122 in ► DIABETES IS TRULY A PRIMARY CARE PROBLEM!!!!

INDICATIONS FOR INSULIN PUMP THERAPY ► INTERMITTENT INSULIN INJECTIONS ARE NOT MEETING TREATMENT GOALS AND OUTCOME MEASURES ARE SUBOPTIMAL, INCLUDING BUT NOT LIMITED TO: 1. Frequent and unpredictable fluctuations in blood glucose levels. 2. Patient perception that diabetes management impedes the pursuit of personal or professional goals. 3. A1C > %, accompanied by frequent severe hypoglycemia ( %, accompanied by frequent severe hypoglycemia (<55mg/dl). 4. Hypoglycemic events requiring third-party assistance or interfering with work, school, or family obligations. ► 2009 The American Association of Diabetes Educators.

INDICATIONS FOR INSULIN PUMP THERAPY ► RECURRENT HYPOGLYCEMIA, NOCTURNAL HYPOGLYCEMIA, ACTIVITY-INDUCED HYPOGLYCEMIA AND HYPOGLYCEMIC UNAWARENESS. ► PREGNANCY ► RECURRENT DIABETIC KETOACIDOSIS ► DAWN PHENOMENON ► GASTROPARESIS ► PATIENT PREFERENCE, MEAL-TIMING FLEXIBILITY AND NORMALIZTION OF LIFESTYLE

INSULINS USED IN PUMP THERAPY ► HUMALOG ► NOVOLOG ► APIDRA ► HUMULIN U-500?

KEY CONCEPTS ► BASAL INFUSION – PROVIDES CONTINUOUS INSULIN INFUSION TO MIMIC THE PANCREAS IN THE FASTING STATE. ► CARBOHYDRATE RATIO OR MEAL BOLUS – THE NUMBER OF CARBOHYDRATE GRAMS COVERED BY 1 UNIT OF INSULIN. ► INSULIN SENSITIVITY FACTOR – THE BLOOD GLUCOSE (mg/dl) THAT IS LOWERED BY ONE UNIT OF INSULIN.

STARTING INSULIN PUMP THERAPY ► CALCULATE THE TOTAL DAILY DOSE (TDD) INSULIN AND REDUCE THIS BY 10%. FOR EXAMPLE – 60 KG FEMALE ON 30 UNITS OF RAPID ACTING INSULIN (10U TID WITH MEALS) AND 30 UNITS OF LONG ACTING INSULIN AT BEDTIME. FOR EXAMPLE – 60 KG FEMALE ON 30 UNITS OF RAPID ACTING INSULIN (10U TID WITH MEALS) AND 30 UNITS OF LONG ACTING INSULIN AT BEDTIME. TOTAL DAILY INSULIN 60 UNITS SUBTRACT 10% = 54 UNITS TDD TOTAL DAILY INSULIN 60 UNITS SUBTRACT 10% = 54 UNITS TDD

BASAL RATE 1. TAKE TDD AND DIVIDE BY UNITS/2 = 27 UNITS/DAY 54 UNITS/2 = 27 UNITS/DAY 2. DIVIDE THE TOTAL BASAL REQUIREMENT BY 24 HOURS. 27/24 = ~1.15 UNITS/HR. 27/24 = ~1.15 UNITS/HR.

CARBOHYDRATE RATIO – 450 RULE ► 450 DIVIDE BY THE TDD 450/54 = ~8 THEREFORE 1 UNIT INSULIN FOR EVERY 8 GRAMS CARBS. 450/54 = ~8 THEREFORE 1 UNIT INSULIN FOR EVERY 8 GRAMS CARBS.

INSULIN SENSITIVITY FACTOR – 1700 RULE ► 1700 DIVIDE BY THE TDD 1700/54 = ~30 THEREFORE ONE UNIT OF INSULIN LOWERS THE BLOOD GLUCOSE BY 1700/54 = ~30 THEREFORE ONE UNIT OF INSULIN LOWERS THE BLOOD GLUCOSE BY 30mg/dl. 30mg/dl.

INSULIN PUMP SETTINGS ► BASAL INSULIN 0000 AT 1.15 UNITS/HR AT 1.15 UNITS/HR. ► CARB RATIO 0000 AT AT 8. ► INSULIN SENSITIVITY 0000 AT AT 30. ► BLOOD GLUCOSE TARGET mg/dl mg/dl. ► ACTIVE INSULIN TIME 3HRS. 3HRS.
