Instructor:

Gary Scheiner MS, CDCES

Technology finally has us to the point where insulin dosage adjustments can be made automatically by using a hybrid closed loop system.  Like any new technology, these systems have their share of pros and cons.  Is automated insulin delivery right for you?  How do you choose the right system and system components?  And how do you ensure the system you use is safe and gets you the results you’re looking for?  Learn all that and more!

Specific topics include:

  • The reasoning behind automated insulin delivery
  • Key components of hybrid closed loop systems
  • What the systems can and cannot do
  • Comparisons of the available options
  • Do-It-Yourself (DIY) alternatives
  • Prepping for a successful transition
  • Balancing safety against aggressive control
  • Optimizing system performance

Placement Exam: Catch the Wave: Automated Insulin Delivery

1. Which of the following is NOT part of current hybrid closed loop systems?

A. An insulin pump

B. User-administered meal boluses

C. Automated glucagon infusion

D. An integrated continuous glucose monitor

E. A control algorithm

2. In order to achieve the best results, hybrid closed loop system users should:

A. Test and fine-tune basal settings with the closed loop system running

B. Reduce basal settings by 20% when starting the closed loop mode

C. Reduce bolus settings by 20% when starting the closed loop mode

D. Test and fine-tune basal settings before starting closed loop mode

E. All of the above

3. Non-regulated, do-it-yourself hybrid closed loop systems:

A. Provide the same level of customer support as commercially-available systems

B. Are easier to set up than commercially-available systems

C. Offer greater setting customization than commercially available systems

D. Require pumps and sensors that are not readily available

E. Only work with Android-type phones

4. Hybrid closed loop systems perform which of the following:

A. Temporary adjustments to basal insulin delivery based on glucose levels and trends

B. Automated bolusing for any size meal

C. Automated bolusing for small meals only

D. Automated extension of boluses for slowly-digesting meals

E. A “learning” algorithm that adjusts base settings based on historical data

5. Which of the following is true when using a hybrid closed loop system:

A. No adjustments are usually needed to prevent hypoglycemia during exercise

B. Less-than-usual carbohydrate will be needed for treating hypoglycemia

C. Infusion sites will not last as long as usual

D. Infusion site issues are easily overcome by the control algorithm

E. It is better to bolus after eating rather than before

Answers: C, D, C, A, B

  • Answered 4 or 5 correctly?  Nice job, Professor!  Looks like you know your stuff.  Maybe you could teach a course on this subject! But there are always new things to learn.
  • Answered 3 or fewer correctly?  You may have a thing or two to learn.  You would certainly benefit from taking this class.
