diagnosis offset for acute conditions

[ireneangelucci]

I am looking at the diagnosis table. It includes both acute and chronic conditions. I assume that the offset for chronic conditions only represent when the diagnosis was entered in the eCare Manager and not when the diagnosis was made.
However I am interested in acute conditions and the time at which the condition occurred is fundamental for my research project. Does the offset for acute disease correspond to when the diagnosis was made? If not exactly, at least in the span of a couple of hours.
I would gladly appreciate if someone was able to clarify on this. Thank you.
