I've been using insulin since 1958. However, I've not found any one with any interest it it. That first month, my average was 141.5, mean 128 and SD 76.1. I knew that was terrible but just tried to lower it by myself. Last month, February 2008, my average was 93.1, mean 86 and SD 41.5. I also track the percentage of readings that fall between 79 and 121. The first month was 20%, last month 33% That's progress but I guess I've got a ways to go!

It'll give you the std dev, average, hirsch ratio and a bunch of graphs. Quite nice really. You might want to head over to the nice chaps as http://sweetspot.dm and upload your meter data there.

My A1c has been about the same before and after starting pump therapy. Before the pump I had lows everyday and up and down like a yoyo. After the pump I rarely have lows.My A1c says I havent improved but in my heart I know I have. I agree with this SD priciple. My A1c has been about the same before and after starting pump therapy.

Dr. Hirsch was my doctor for eight years and he he checked my SD and A1c. Though he didn't have the formula worked out yet he used these numbers to provide me with the best care. I'd like to say that we diabetics are lucky to have Dr. Hirsch working for us. He is a diabetic himself and the most compassionate and caring doctor I have ever had in my fourty-one years as a diabetic. I have since moved to Sacramento and have yet to find medical care anywhere close to what Dr Hirsch provided me.

You asked "Anyone out there using the SD formula successfully yet?" Well, I am; however, I'm Type-II not Type-I. Initially, my A1c was 7.2 in Aug'03 when I was first diagnosed as diabetic type-II. It's now been down at 6.2 for last 3 consecutive 6-month interval tests. This year my accumulative weekly average (mean) blood glucose values are: BFAST = 109 mg/dl, SD = 14 LUNCH = 110 mg/dl, SD = 14 DINER = 117 mg/dl, SD = 20 And, thus, my MEAN/SD ratios are: BFAST = 109/14 = 7.8 LUNCH = 110/14 = 8.0 DINER = 117/20 = 5.7 To "keep" my diabetes "under control," my physician tells me to "keep" my MEAN/SD-ratio at 4:1, or higher (preferrable). So, my "goals" are MEAN = 100 and SD = 5. So, "Yes," I am using SD! re: your article “Standard Deviation Buzz.” You asked “Anyone out there using the SD formula successfully yet?” Well, I am; however, I’m Type-II not Type-I.

Initially, my A1c was 7.2 in Aug’03 when I was first diagnosed as diabetic type-II. It’s now been down at 6.2 for last 3 consecutive 6-month interval tests.

This year my accumulative weekly average (mean) blood glucose values are:

BFAST = 109 mg/dl, SD = 14
LUNCH = 110 mg/dl, SD = 14
DINER = 117 mg/dl, SD = 20

And, thus, my MEAN/SD ratios are:

BFAST = 109/14 = 7.8
LUNCH = 110/14 = 8.0
DINER = 117/20 = 5.7

To “keep” my diabetes “under control,” my physician tells me to “keep” my MEAN/SD-ratio at 4:1, or higher (preferrable). So, my “goals” are MEAN = 100 and SD = 5.

So, “Yes,” I am using SD!

I started logging all my blood sugars in December 2004. I started Dr. Bernstein's diet/exercise program on January 12, 2005. In December, my actual SD exceeded avg/3 by 25 mg/dL. Since then, it has consistently fallen every month, to +7 mg/dL in June. NOW, in July,for the first time since starting the Bernstein regimen, my SD has dropped below avg/3 by 2 mg/dL. WOW!!! I knew my glycemic control had dramatically improved, and that for the first time in thirteen years I felt in complete control of my type 1 diabetes. But now, for the first time, you've given me an objective way of quantifying my control. THANKS!!! This is important. Really important. It is the first positive thing I've had in the last couple of months. And they've been a really, really rough couple of weeks. Last week I actually lost the will to live. I am still very, very depressed. I am just taking it half a day at a time right now... Hmm….Standard deviation (mg/dL) vs. one-third of average blood sugar (mg/dL)?

One of the web-based reports enlisted the mean blood sugar levels over 14 days plotted against the standard deviation and showed all of the patients on a single graph. You can imagine how insightful this report was especially as the relative patient control changed over the course of the 4 month study. We learned some interesting things through this research including the ability to efficiently identify those patients in most need of intervention. A1c clearly falls short when it comes to understanding which patients to focus on in a proactive healthcare system. Another number which we identified as a valuable 3-Dimensional statistic in addition to A1c and SD is the percentage of hypoglycemic bg tests. With those 3 markers we should be able to create a significant improvement in the "gold standard" for diabetes. The study was conducted by Stephen Ponder, MD CDE and presented at the Diabetes Technology Society Meeting in November 2003.

Hmmmm......this is interesting. I started putting my blood sugar readings in a spreadsheet in December. I calculated daily average, running 7-day average, and average error (absolute value of difference between reading and 90 mg/dL). So far for the month, my average is 103 mg/dL. I just calculated the SD--33. So that's just about right--a third of average. The average error is 9 mg/dL. Thanks for sharing the idea. I will use this new metric to assess my control.

The big secret of diabetic control is that your average BG doesn't have much to do with how well controlled you are...you can get your average to be wherever you want it by adjusting your treatment. The real trick is keeping away the lows and the highs...and that's what people mean (or should mean) when they talk about control. I posted this elsewhere on the site, but someone with an average of 130 and a standard deviation of 20 is far better controlled than someone with an average of 110 and a standard deviation of 60.
