We are thinking about how to structure our data into the OMOP CDM, and have a question about how to group clinical events.
Lets say that a patient does the following:
- The patient goes to a medical facility.
a. They see their PCP, who examines them, and takes some vitals.
b. The PCP then collects a blood sample to be sent off for some lab work.
(The PCP then sends the patient to their neurologist for an exam)
c. The patient then sees their neurologist and gets the exam
d. The patient then goes to radiology for an MRI, and is consulted by the radiologist
e. Finally, the patient stops at the pharmacy on the way out to pick up their meds
Does this example constitute a single visit (1), or three visits (a,c,d), or five visits (a,b,c,d,e)?
if the answer is greater than one, what table in the CDM can I use to group these events into a single “episode of care”?
