my CDAI is 226 and I'm in Australia. I think dusty is VERY correct though.. it really does rely too much on D.. as one of the options was 'loose stool OR D' I went with the loose ;-D
that was calculated using this cdai
http://www.ibdaustralia.org/cdai/
and this one
http://www.ibdjohn.com/cdai/ the score is CDAI = 135.7
and 9 on this one
http://www.gastrotraining.com/calculators/harvey-bradshaw-index-hbi
I have NO idea what these scores mean so am off to investigate
A little late perhaps, but as the author of that first calculator page linked (now at
www.ibdsupport.org.au/cdai-calculator) I may be able to shed some light on that
My script is written primarily for the Australian Medicare system, which uses a slightly modified CDAI for eligibility for publicly funded access to biologics. However, it turns out all they've done is actually add a maximum deduction of 10 points if you're overweight, which in my script can be disabled with a checkbox next to the weight section.
With the standard CDAI system, remission is typically accepted to be a score below 150, while a score above 300 is considered a flare, but other scores eg 200, 220 or 250 may be used as cutoffs for eligibility to clinical trials etc
The site
www.ibdjohn.com/cdai (as used in the wiki) uses an earlier form of the CDAI which is not [as] widely recognised, and results in significantly lower scores than the typically accepted CDAI. That said, it's fine to use and arguably better if all you're after is a relative score to track your progress, but it's not going to directly correlate with the scores that people may use.
The Harvey Bradshaw index is a different scale that I'm not familiar with, but these two do seem to be the most well known and used of the scores for IBD. Though note as the name may suggest, CDAI is not really intended for use in IBDs other than CD, which can be problematic.
Unfortunately all these scales are far from perfect, and as noted by others the CDAI depends heavily on D when most of us may instead suffer from C which is harder to quantify. Also, the "general well-being" section is highly subjective and is responsible for a significant portion of the final score.
