Objectives

Before and After Insulin Treatment

Discovery of insulin in 1921 changed type 1 from a death sentence to a chronic disease

7-year-old child before and 3 months after insulin therapy

Do We Need Technology?

We’ve Come a Long Way!

So….. this means my blood sugar is between something and something

This tastes sweet, it must be Diabetes Mellitus

Insulin Delivery Modes

Insulin Delivery Modes - Pens

The prototype of the first pump that delivered glucagon as well as insulin, backpack style, was in the early '60s.

Omni Pod - the world’s first tubing-free insulin pump.

Recommended Goals for Therapy

A1C

<7.0%*

Preprandial capillary plasma glucose

80–130 mg/dL* (4.4–7.2 mmol/L)

Peak postprandial capillary plasma glucose†

<180 mg/dL* (<10.0 mmol/L)

*Goals should be individualized. †Postprandial glucose measurements should be made 1–2 h after the beginning of the meal, generally peak levels in patients with diabetes.

ADA. 6. Glycemic Targets. Diabetes Care 2015;38(suppl 1):S37; Table 6.2

∗Goals should be individualized based on ∗Duration of diabetes ∗Age/life expectancy ∗Comorbid conditions ∗Known CVD or advanced microvascular

complications ∗Hypoglycemia unawareness ∗ Individual patient considerations

Glycemic Recommendations for Adults

ADA. 6. Glycemic Targets. Diabetes Care 2015;38(suppl 1):S37; Table 6.2

Glycemic Recommendations for Adults

∗More or less stringent glycemic goals may be appropriate for individual patients

∗ Postprandial glucose may be targeted if A1C goals are not met despite reaching preprandial glucose goals

Glucose Monitoring

Software

• Check pre and post BS readings • Make Changes

• Look at insulin or medication

• CHO count

• Assess food impact

Respond to the Data!

∗ Pattern assessment and Treatment Change -

∗ Basal Testing

∗ Prevention of hypoglycemia

∗ Prevention of hyperglycemia

∗ Assess the impact of food on blood glucose

∗ Assess the impact of exercise on blood glucose

∗ Behavior modification tool

∗ Alerts/Alarms: Safety, peace of mind…

Why Continuous Glucose Monitoring? Professional and Personal

• Increased security from alarms & alerts

• Immediate feedback - look and learn

• BG trend provides more information than static readings

• Control + safety

Benefits ofPersonal CGM

Glucose Monitoring - CGM

• by analyzing the trends, the patient or the physician can adjust insulin • leads to better glycemic control

100 mg/dl Glucose reading

OR

100 mg/dL dropping at rate of >2 mg/dL/min

Is CGM Better than FSBG?

FSBG – just a moment in time CGM adds an additional dimension, the rate of change and direction of change.

Trends Better Than Points

I have no clue

I feel fine but my

blood sugar is dropping!

Clinical Need – hypoglycemia, hypoglycemia unawareness, uncontrolled hyperglycemia

MOTIVATED patients/parents!

Willingness to learn and understand the process: it may be a rocky start

Understanding of how to use the data

Likely Candidates for CGM

Rate of Change Arrows

Gives the up-to-the-minute glucose value and a rate of change arrow

Glucose going down -1 to -2 (mg/dL)/min

Glucose going up 1 to 2 (mg/dL)/min

Glucose falling quickly >-2 (mg/dL)/min

Fairly stable glucose -1 to 1 (mg/dL)/min

Glucose rising quickly >2 (mg/dL)/min

Glucose Trends – CGM Report

Post-breakfast excursion

• There is a 10-20 minute lag time between interstitial fluid (ISF) glucose and BG

• Lag occurs with ALL subcutaneous sensors

• CGM is a trending device, NOT a treatment device

Sensor Lag Time: FSBG doesn’t always match the meter

∗ No ~~ BG need to be done: 1. Before all treatment decisions and insulin

2. To verify symptoms of hypoglycemia

3. Before driving

4. Calibration

5. Before Activity

Does Using a CSM eliminate the need for glucose checking?

• The accuracy of all the CGM’s are dependent on the calibration phase

• Devices calibrate in 1-2 hours

• Must do a fingerstick BG to calibrate

• Do NOT calibrate when the BG is changing rapidly

When to calibrate?

1. Change behavior! • Bolus • CHO count • Assess food impact

2. Change Treatment

Insulin Pumps on the Market

∗ More reliable, precise insulin action ∗ Fewer missed doses ∗ Less insulin, less insulin stacking ∗ Fewer lows, especially at night ∗ Easier to exercise ∗ Less glucose exposure and variability ∗ Matches variable basal insulin need ∗ Fewer social limitations ∗ Better data access for providers and patients

Pump Advantages

∗ Improved Glycemic Control

∗ Improved pharmacokinetic delivery of insulin Less hypoglycemia Less insulin required Match insulin requirement to need

∗ Improved Quality of Life

∗ NOT NECESSARILY LESS TIME CONSUMING

Clinical Advantages of CSII

Method 1. Pre-Pump Total

Daily Dose (TDD)

Pre-Pump TDD x .75

Method 2. Patient Weight

Wt kg x .5 or lb x .23

Pump TDD

Calculations for Insulin Pump Settings

Basal Rate

(Pump TDD x .5) / 2- h

Sensitivity Factor / Correction

1700 / Pump TDD

-Start with 1 basal rate, adjust according to glucose trends over 2-3 days -Adjust to maintain stability in fasting state (between meals & during sleep) -Add additional basals according to diurnal variation (dawn phenomenon)

Carb Ratio

450 / TDD

-Adjust based on low-fat meals with known carbohydrate content -Acceptable 2-h post-prandial rise is ~60mg/dL above pre-prandial BG -Adjust carb ratio in 10%-20% increments based on post-prandial BG ALTERNATE METHODS -Carb Ratio: (6x Wt in kg / TDD) or (2.8 x Wt in lbs / TDD) -Fixed Meal Bolus = (TDD x .5) / 3 equal meals (not carb counting)

-Sensitivity Factor is correct if BG is within 30 mg/dL of target range within 2 hours after correction -Make adjustments in 10%-20% increments if 2-hr post- correction BGs are consistently above or below target

Clinical Considerations on Pump TDD -Average values from Method 1 & 2 -Hypoglycemic patients start at lower value -Hyperglycemic, elevated A1C, or pregnant start at higher value

Clinical Guidelines

TDD: total daily dose BG: blood glucose

1. Change behavior! • Bolus • CHO count • Assess food impact

2. Check basal rates

3. Use alarms
