Discharged_to_concept_id

Hello!
We previously used Home (concept_id = 8536) for the discharged_to_concept_id field in the visit_occurrence table. However, this concept is no longer a valid standard option and now maps to Home Visit (concept_id = 581476), and there is no standard “Home” concept in the Visit domain that can be used for discharged_to_concept_id.

According to the OMOP documentation:

“discharged_to_concept_id: This concept is part of the visit domain and can indicate if a patient was transferred to another hospital or sent to a long-term care facility, for example. It is assumed that a person is discharged to home therefore there is not a standard concept id for ‘home’. Use concept id = 0 when a person is discharged to home.”

Because we have a large volume of records without discharge information, we would like to differentiate between “Home” and “No information”, rather than treating both as concept_id = 0.

Could you please advise on the recommended approach?

@Jungmi:

No need. Discharge to by definition means another visit concept, which is a healthcare encounter. Meaning, the care is not over, but continues elsewhere in the healthcare system. If the patient is discharged home, or to the cruise ship, or to prison, or to the foreign legion, or any other place is none of our business.

“No information” is a flavor of null, and we don’t record it in principle. What you mean by “home” is perhaps “Not another healthcare facility”. But we don’t record negative information either. We break the tools, if we start doing that.

Makes sense?
