Poor Control Remains A Problem HbA1c 2/3 with diabetes (and most pumpers) remain out of control 10% Avg. A1c in TYPE 1s 9% Avg. A1c on Pumps 8% ADA 7% Goal A1c EASD/AACE 6% 5% ADA = American Diabetes Assoc., IDF = Inter. Diabetes Federation, EASD is European Assoc. for the Study of Diabetes, AACE = American Association of Clinical Endocrinologists Novo Nordisk Type 2 diabetes market research, Roper Starch Wright A., Burden et al, Diabetes Care 2002; 25:330–336 Turner RC, Cull et al, JAMA 1999; 281:2005–2012 Healthcare Across Borders - September 2003

Exposure Versus Variability One day’s tests every 30-60 min with usual meals and insulin. The DCCT proved that exposure to high blood glucose was damaging. New emphasis is on glucose variability. Variability or Swing = Standard deviation or GlycoMark test Exposure or Average = A1c or avg. BG from meter Healthcare Across Borders - September 2003

The Challenge Of Diabetes Bringing the A1c down smoothly takes effort Uncontrolled A1C ~9% 300 (16.7) Time of Day “Controlled” A1C <7% BG in mg/dL (mmol) 200 (11.1) A1C ~6% 100 (5.5) Normal A1C 4%–6% 0800 1200 1800 0800 …for this you need ADVANCED therapy Healthcare Across Borders - September 2003

Use Sterile Technique For Site Prep 30% of people are constant staph carriers and 25% are intermittent. MRSA is now common. Prevent infections: Wash hands Sterilize skin with IV Prep Place bio-occlusive IV3000 over site Insert infusion set through IV 3000 Steps for staph carriers: Use antiseptic soap all over body once every 1-2 weeks Occasionally, apply bacitracin ointment to inside of nose Healthcare Across Borders - September 2003

Tape The Tubing!!! One inch tape over the infusion line stops tugging Tape stops tunnelling – movement of teflon nder skin allows insulin to tunnel to the surface, causing unexplained highs Less skin irritation from movement Prevents pull outs At tug time, lose tape not insulin!

Healthcare Across Borders - September 2003 Pump Start Healthcare Across Borders - September 2003

Healthcare Across Borders - September 2003 Prepare For Pump Start Use basal/bolus approach first with injections Use accurate carb counts Read Pumping Insulin and pump manual Practice with your pump as soon as it arrives View CD/DVD as you practice with your pump Get training in pump operation and troubleshooting Nervousness is normal. If you have access to your pump before the pump start, be sure to take it out of the box and push all the buttons as you watch the pump video. You cannot learn too much and you won’t hurt the pump. Load a reservoir saline if you have some and insert the infusion set. Otherwise, load the reservoir with water, prime the tubing, etc, but don’t insert the infusion set. This practice does not qualify you to start a pump, but can make your pump start much easier and quicker. Healthcare Across Borders - September 2003

Healthcare Across Borders - September 2003 Preparation Ask how to discontinue your long-acting insulin Determine start-up settings for TDD, basal/bolus balance, carb and correction factors, and DIA Get prescriptions for insulin, test strips, IV Prep, IV 3000 dressings, etc. Have contacts for MD, CDE, pump company, pump rep, other pumpers Healthcare Across Borders - September 2003

Healthcare Across Borders - September 2003 Steps To Success Test often Keep great records (Smart Charts, download, etc) Take a bolus for every bite except when carbs are used to raise a low BG or when eating to compensate for exercise Take boluses early Write down a reason for every high and low Change infusion site on schedule and whenever unexpected highs occur Healthcare Across Borders - September 2003

Healthcare Across Borders - September 2003 Steps To Control Stop lows first Set a realistic DIA Determine an optimum TDD Set and test basals Determine starting carb factor with 450 Rule (450/TDD) and correction factor with 2000 Rule (2000/TDD) Periodically check basal/bolus balance Look for and correct unwanted patterns Healthcare Across Borders - September 2003

Stop Lows First Better control and more stability Mild lows cause followup lows Small epinephrine release makes muscles sensitive to insulin Can lead to another low as much as 36 hours after the first More carbs than usual are needed Severe lows cause highs Higher stress hormone release makes glucose rise for 6-10 hrs Excess carb intake leads to highs Boluses may be reduced/skipped More insulin than usual needed To stop lows, lower the TDD!!! Healthcare Across Borders - September 2003

Find Your Optimum Doses! Start with an accurate TDD – 1. How much total insulin do you average a day? 2. Adjust the TDD – are highs or lows primary problem? Stay in basal/bolus balance – 50/50 or 45-65% as basal Use the 500 and 2000 Rules to estimate starting carb and correction factors Then adjust your basal and bolus doses TEST your blood glucose LOOK for blood sugar patterns ADJUST basals and boluses from your patterns Healthcare Across Borders - September 2003

Find Basals And Boluses From Starting TDD Starting Carb Factor Corr. Factor TDD 50% Basal 500 Rule 200 Rule 20 u 0.42 u/h 25 grams 100 mg/dl 25 u 0.52 u/h 20 grams 80 mg/dl 30 u 0.63 u/h 17 grams 67 mg/dl 35 u 0.73 u/h 14 grams 57 mg/dl 40 u 0.83 u/h 13 grams 50 mg/dl 50 u 1.04 u/h 10 grams 40 mg/dl 60 u 1.25 u/h 8 grams 33 mg/dl 3.1 mmol This table shows typical basal rates, carb factors, and correction factors for different TDDs. An accurate TDD solves most control problems! Healthcare Across Borders - September 2003

Duration Of Insulin Action (DIA) Time An accurate DIA time is critical to success on a smart pump Current research suggests that DIA times are NOT different between children and adults Shorter for those more sensitive to insulin, but NOT children in general But immediate factors can affect insulin action time: Shorter with activity and exercise Shorter in hot weather Longer with fat in diet Healthcare Across Borders - September 2003

A low basal rate makes the DIA appear SHORT! DIA Tips If your pump often suggests boluses that you know are not enough, do not shorten your DIA– it is usually NOT the problem Instead, ask what is causing the highs and where more insulin is needed – in basal rates, in carb boluses, or both Exercise or activity can mobilize insulin faster but DO NOT shorten the DIA for occasional activity. Instead: lower boluses or basals ahead of time for planned activities or eat more carbs or lower basals for unplanned activities A low basal rate makes the DIA appear SHORT! Healthcare Across Borders - September 2003

How long a bolus will lower the BG: Bolus Size (Relative To Wt) Affects The DIA Measured as units per kg(2.2 lb) Larger boluses have a longer duration of action. For 50 kg (110 lb) person: 0.3 u/kg = 15 u 15 u/kg = 7.5 u 0.075 u/kg = 3.75 u How long a bolus will lower the BG: 4 hrs Healthcare Across Borders - September 2003 Becker et al. Diabetes. 2005; 54 (Suppl. 1): 1367P

Recommendations For DIA Times DIAs on current pumps can be set from 2 to 8 hours. An inaccurate DIA can significantly impact control. Healthcare Across Borders - September 2003 Mudaliar et al: Diabetes Care, 22: 1501, 1999

When Major Control Problems Occur TDD too low or too high? Adjust your TDD Determine the current TDD Lower it: For frequent lows If both highs AND lows occur – which comes first? Raise it: For a high A1c or a high average BG on your meter While keeping basal rates and the daily carb bolus total balanced Healthcare Across Borders - September 2003

Healthcare Across Borders - September 2003 Adjust The TDD For A High Avg. BG or A1c Example: someone with a TDD of 35 units and few lows. A1c = 9%, so more insulin is needed: about 3.2 units. Healthcare Across Borders - September 2003 © Pumping Insulin, 2006

Healthcare Across Borders - September 2003 Change Your TDD For A change in diet A loss or gain in weight Seasonal changes An overall change in activity Starting/stopping a sport Vacation Growth or start of puberty Menses Healthcare Across Borders - September 2003

Healthcare Across Borders - September 2003 Look For Patterns Frequent highs Frequent lows High at B/L/D/Bed Low at B/L/D/Bed Low to high High to low Check Insulin Use Similar TDDs day to day Basal/Bolus balance Correction bolus % Healthcare Across Borders - September 2003

Healthcare Across Borders - September 2003 Basal Rates Should keep the blood sugar flat overnight or when a meal is skipped Relatively easy to test See Pumping Insulin for details Healthcare Across Borders - September 2003

Healthcare Across Borders - September 2003 Set & Test Basals First In reducing TDD, take into account A1c, history of highs or lows Pre-Pump TDD More Accurate TDD (55-95% of Pre-Pump Dose) 50% basal is a good place to start for adults and many children 40 - 65% Basal 30 - 55% Bolus Test Basal Rates First Healthcare Across Borders - September 2003 © Pumping Insulin, 2006

Healthcare Across Borders - September 2003 How Many Basal Rates? Percentage of pumpers who use 1 to 10 basals per day from self reports of several hundred pumpers at insulin-pumpers.org % These are the percentages of pumpers who use 1 to 8 basal rates per day. One basal rate may work in children, while the complex metabolism of puberty often requires multiple rates Healthcare Across Borders - September 2003

Healthcare Across Borders - September 2003 Basal Tips 50% Rule: basals usually make up 40 to 65% of an accurate TDD Basal rates will be similar through the day, such as between 0.45 and 0.7, or between 1.0 and 1.4 Adjust basal rate in small steps – 0.05 to 0.1 u/hr Change basals 3 to 8 hours before need arises Unlike boluses, basal changes are small and must be made several hours before their effect is desired.

Healthcare Across Borders - September 2003 Carb Counting Accounts for half the day’s control Accuracy allows boluses to match carbs for post-meal control and a significantly lower A1c Made easier with automatic carb bolus calculations by pump Carb counting is a great control tool because it directly measures the portion of a meal that raises the glucose. Healthcare Across Borders - September 2003

Carb Factor Carb factor – how many grams of carb are covered by 1 unit Carb bolus is based on: Your carb factor How many grams of carbs you plan to eat Your BG allows a correction bolus determination Amount of BOB still active (ALSO determined from BG!) A pump can determine the bolus needed for a meal when the carb count and the carb factor are accurate Visit your dietician to learn! Healthcare Across Borders - September 2003

Check Your Carb Boluses Does your carb factor work for LARGE meals? – half your weight (lbs) as grams of carb Are carb counts accurate? Are boluses given 20 min before meals when the glucose is normal? For frequent lows after meals –> raise carb factor # For frequent highs after meals –> lower carb factor # Healthcare Across Borders - September 2003

An Accurate Carb Factor Returns the blood sugar: to within 30 mg/dl (1.7 mmol) of where it started by the time selected for your duration of insulion action (DIA) with no lows within 5 hours after carb bolus given Simple ways to check the carb factor and carb bolus doses. Healthcare Across Borders - September 2003

Healthcare Across Borders - September 2003 Carb Bolus Varieties Normal carb bolus Bolus taken immediately – most meals Extended or square wave bolus Bolus extended over time – gastroparesis Combo or dual wave bolus Some now, some later – bean burrito, some pastas and pizzas, Symlin Healthcare Across Borders - September 2003

Most Carbs Much Faster Than “Rapid” Insulin One hour after a meal, half of a meal’s glucose rise has occurred, but 80% of rapid insulin activity remains Time over which most meals affect the BG % bolus activity remaining Take Home: Bolus 15 to 30 minutes before meals Use extended and boluses sparingly.
