| |
| * What is the relevance of this? I took it from the paper manual, but it does not say there why included. Dx coding? APACHE II Chronic entry?
| |
| ** The relevance is for all of these things.--[[User:LKolesar|LKolesar]] 21:24, 15 May 2008 (CDT)
| |
| *** So does this affect how Chronic Health gets coded? Or how a particular Dx gets coded? Or what? [[User:Ttenbergen|Ttenbergen]] 12:48, 17 October 2008 (CDT)
| |
| *** If the relevance is for all diagnoses, then we should include the diagnosis codes (like in the other dxs) and add it to the diagnosis. If it's for APACHE II, it would be nice to explain the relevance a touch better. If I understand right, we pull the angina score for the APACHE II from the L_Dxs entries, right? If so, then really for APACHE II all we should say is that it's pulled from there, and then link to the Angina DX coding entry, as not to duplicate text in here which can then become inconsistent.

| * provide better reference - the Canadian Cardiovascular Society website only has some of this at best.
| |
| I will try to obtain a better reference for this material, I think there is likely a much simpler way of defining this. Then there should be a link to apache, diagnosis and chronic hx. --[[User:LKolesar|LKolesar]] 12:29, 16 May 2008 (CDT)

| * Is there a reason the classes are numbered normal for one angina and Roman for the other? [[User:Ttenbergen|Ttenbergen]] 13:05, 17 October 2008 (CDT)
| |
| * This whole section needs a revamp. STABLE ANGINA does not have 4 categories , this should read ANGINA only. Class 3 and 4 in this written section is considered unstable angina. I would personally take out the clinical circumstances section as well. --[[User:LKolesar|LKolesar]] 13:20, 17 October 2008 (CDT)
