  1. Simulate Use Data (All participants)


Prompt:


  • Please treat this as if you were actually administering a dose and follow ALL of the steps you normally would if you were administering a dose to someone at home.


  • Just so you know, you will be injecting into this injection pad (indicate injection pad) that will be placed on Sam. I’ll set up the injection pad on Sam for you in the location that you select, whenever you are ready for that step.


  • Now, I want you to imagine that you are the caregiver for Sam (point to manikin). Sam is a diabetic and has just been given this prescription from his/her doctor (show prescription card) and provided with an insulin pump set (point to pump and accessories in cabinet). Let’s imagine that you are at Sam’s home, and this is the first time you need to use the new pump to deliver Sam’s insulin dose.


  • Sam’s doctors checked his/her blood-glucose levels and determined that the pump needs to be set up to deliver several doses of insulin throughout the day and should be set to deliver at 12am, 7am, and 1pm, as written on the prescription.


  • Sam needs your help to set up the insulin pump to deliver the correct dose.


  • When you are setting up the time and date on the pump, please set it to today’s date at 3:30 pm. For purpose of today’s session, we will imagine it is 3:30 pm when you set the time (show time prompt card).


  • Please note that I may stop you at times to check something. This doesn’t mean you did something wrong; I just may not have been able to see what was going on.


  • Whenever you are ready, please proceed to set up the insulin pump and deliver Sam’s first dose, based on the doctor’s prescription.
