Admitting_source_concept_id when admitted from home

CDM or THEMIS convention?

CDM

Table or Field level?

Field

Is this a general convention?

No

Summary of issues

• According to visit_occurrence table definition, the field admitted_source_concept_id is used to determine where the patient was admitted from.
• It is a required field and should be filed by a standard concept in the Visit domain.
• Although there is a concept for admission from Ambulance, from Outpatient clinics, and more, I can’t find a concept for visits which were admitted by self-referral (or no referral). This is the common case for ER visits.
• Which concept is the most appropriate for admitting_source_concept_id?

Summary of answer

Author 1: concept_id=0, because a visit concept by definition describes the interaction between a patient and the healthcare system. If there was no such interaction there is no visit concept.

• Based on the following Github issues the final answer is:

Documentation for the field ADMITTING_SOURCE_CONCEPT_ID in the VISIT_OCCURRENCE and VISIT_DETAIL tables need to be updated to include setting the field to zero when the person is admitted from home.
