Hassles and Limitations of the Hybrid Closed Loop System

Unexpected tasks	“I checked way, way more than I normally do at home.” (adult, System B) “I thought I had a lot of input on this closed loop. Just like responding to the alerts and the meal boluses and I didn’t really like that.” (adult, System A)
Hard to wear	“The taping method on this is intense. There’s a lot of tape going on your skin. I would think even on a little kid you’re not going to have that much space, or on somebody that’s just smaller.” (adult, System B) “It wasn’t such a big deal for me to carry [extra devices] for the study, but I think for home use and personal use, it would be a little tough to keep with you or on your person.” (adult, System B)
Not responsive enough to highs given what I can achieve on my own	“I’m not worried about lows. I’m worried about highs. So having those highs is what frustrated me. . . . given what I keep such tight control.” (adult, System A) “Only 30% of people are at the target A1C. That means for the bigger picture of diabetics in the world, [this system] would be good. But for me personally, maybe not.” (adult, System B)
Being reminded of diabetes	“I think I still thought about everything just as much or more. It didn’t really take away from the diabetes burden.” (adult, System B) “I was still feeling my diabetes. I still thought about it constantly. I felt just as much or more burden. It wasn’t any easier in that way.” (adult, System B)
