Has anyone tried john walsh's new pump algorhythm on his website? It comes from some data from some boatload of pump users and has apparently a means to take your two week mean, current weight and current insulin use, to come up with ideal settings, based upon this large group of users segmenting out the ones who had good control...
we have tried it with mixed results, the basals seemed right but the carb ratios too low ( too much insulin)
he says that users adjust settings based on bogus information, not utilizing enough evidence based science, and rely on carb ratios out of habit, rather than systematic evidence.
take a look and let me know what you think?
he has some very nice presentations that support this, but obviously we'll want to talk to our endo's about it!
Our endo at vandy had not seen it yet, so he is taking a look and getting back to us!
oh here is the site...
diabetesnet.com under " tools"
If you access the tool via opensourcediabtes.org:
the disclaimer actually requires you to state that:
"I AGREE THAT I WILL NOT CHANGE ANY OF MY PUMP SETTINGS OR INSULIN DOSES UNTIL I DISCUSS THEM WITH AND GET APPROVAL FOR THESE CHANGES FROM MY PHYSICIAN."
(Scare quotes from me but ridiculous capital letters from them.) The best two physicians I've dealt with (one a T1 endocrinologist in the UK, one a simply wise family doctor in Oregon) know well enough never to tell a T1 what to do.
It's really not that we know best, it's simply that it is our life to do with as we choose.
Artificial pancreas is very exciting. In Portland they are quite far in the project. Apparently FDA have approved this year some project letting the project advance further. I know that they are doing some inpatient testing of system. For me it is a bit difficult to imagine. I will have a hard time giving up the control and trusting insulin delivery to the device. I am fully aware that this could be the argument against pump use in the past. :-)
It is amazing how many advances in diabetes management we are enjoying, starting with Banting and, ability to check bs with strips, and now pumps, sensors, .... I am very thankful for all the time and energy people continue to put in treatment of T1.
Dexcom didn't work for me, I sent it back and disputed the charge (on my credit card, my insurer didn't give a damn). Not a single one of the Dexcom devices lasted the stated time, Dexcom agreed to replace every one I had, and the readings compared to blood tests showed no agreement (correlation maybe, but no agreement.)
The reports are that other CGMs are better, but they have been discontinued in the US because of patent issues.
I had bad experience with old DEXCOM and minimed sensor. I have been using the new Generation 4 DEXCOM since November, a huge difference. The accuracy is superb! It is such a nice surprise.
Wow, the calculations I got were a complete change. I wouldn't use it.
My original thought was that in diabetes, science, politics etc etc there's always another "expert" with an opinion. I'd rather use the averaged opinion of many rather than just one person's opinion. Much safer that way it seems to me. I took my doctor's original settings and then called Insulet to get their suggestions. They were almost identical. And, have worked since day 1. My BG's would be in the 500's using Mr Walsh's idea of settings for me.
