I ran across this interview from a few days ago where Stacy Simms (Diabetes Connections) spoke with Dr. Laurel Messer, senior director of medical affairs at Tandem. I found the content well worth the time spent. I was amazed to hear how the algorithm performed even when patients routinely didn’t dose for meals/snacks. Dr. Messer stressed, numerous times, how if you want to tighten and lower your time in range, the correction factor is the setting to focus on. Now, I know some disagree with her but I felt she was talking directly to those of us who want to, essentially, over-ride the 60% max dose for CIQ’s automatic corrections. You know, blood glucose control high achievers. Anyhow, I follow this advice and found it to be valuable. The link to the interview is here: https://www.youtube.com/watch?v=g3LnCaWfIgY
This is an interesting interview. Thank you for sharing the link, @mremmers.
I liked the part where she was talking about reducing the mental burden for diabetics and the pursue of an insulin pump with no need whatsoever to bolus. There is no point in stressing the patients to bolus if they don´t. Instead they hack it by making a pump that auto boluses. If you set the correction factor strong enough this will work.
Tandem tries to make pumps that fit diabetics and how they actually live without neglecting the users who both boluses and has tight control. I also applaud the way she explains the thinking around Tandems chosen target range.
I listened to the interview, and was glad to see some changes to the CIQ. Good to hear that temp basal function is back (one of the best things about BIQ - and why I stay with BIQ for as long as I can). The automated insulin infusion of CIQ isn’t all that important to me. I don’t allow myself to get above 150 bg (yes, I still get rogue numbers, but not often and I aggressively correct using correction titrated bolus and temp basal increase). I am hoping for the opportunity to set out own target. I understand the “target” as used in diabetes-speak being 110 bg. But that’s kinda like the old (and outrageous cuz it is so damn high) goal of an A1C at 7 (which = 172 as an average bg!). I want to be able to set my own “bolus target”. I prefer a bolus target - where I want my bg after a correction/meal bolus has done it’s job - to be 80-90.
I agree with your point about CIQ and BG range.
Personally, I’ve found using “sleep” mode overnight to be pretty effective at keeping my blood glucose within my target range, protecting against both highs and lows.
So that is probably the biggest pro for me.
