We are interested in mapping surgery admission and discharge dates in two separate observations. From what I can see in Athena there are two good choices:
LOINC: 3040041 (Admission date), 3042411 (Discharge date)
SNOMED: 4161014 (Date of admission), 40485383 (Date of discharge)
I was wondering if there is a preferable community aprooach to this so that our decision can be more interoperable with other data holders.
Thank you in advance.
