I have a database of diabetic patients. Mostly 80 % are T2DM patients. Now I would like to identify the T2DM patients based on their conditions reported. I mean when patients visit hospital (diabetic specialist clinic), they report/record their conditions.
Is it normal to consider items like
Type 2 diabetes mellitus with Ulcer or
Rubeosis iridis with T2DM or
Retinopathy with T2DM etc as diagnosis for T2DM?
I thought we should only look for
Type 2 diabetes mellitus in condition table because this to me seems like a diagnosis for T2DM. But can the above (or similar) items be considered for T2DM diagnosis and if yes, why? Because I see it is being considered
Can you help me understand this?
