Capture one-sided events as formal events in CDM #287

Closed vojtechhuser closed 3 years ago

vojtechhuser commented 5 years ago

OMOP currently captures visits. Where a patient AND provider interact.

If a patient logs into PHR or provider mails a letter to the patient, it is a one sided event. Just patient does something or just provider does something.

From patient care and research point of view (e.g., on PHR side, ability to recruit into a applicable research study via PHR), such events matter and can be important for research.

One person commented on the forum so far. Please use the like button on the top post or post your opinion here. This was inspired by listening to EHR group discuss import of visit data from Epic. Epic has as a vistit also a 'mail a letter event'. And currently the ETL was simply discarding such events as non-visits. But getting a letter about some important test result or being asked to follow up with the doctor seems like an important event not to delete from CDM. (think "beyond claims EHR data")

@vojtechhuser many of the event tables in the CDM do not require a visit_occurrence_id to be considered a valid event. Can these one-sided visits you are describing be added to the tables with a date but no visit? That is entirely plausible within the current bounds of the ETL and CDM specifications.

I was not arguing that it needs to go to VISIT_OCCURRENCE table. Just somewhere - based on discussion of the group.
So given your reply - would you say it such an event is an OBSERVATION?

And if it is - what observation_concept_id it would be? (login to PHR, letter mailed). SNOMED does not have a concept for it (I am guessing). We would have to create OMOP concepts for those or "sell it/advertise it" to an existing terminology (LOINC?)

Closing as this is handled in the conventions in #358
