Summary of issues

• If patients are still in the hospital at the time of the ETL build, set the visit_end_date to the date of the data extract and set the discharge_to_concept_id to 32220.

Summary of answer

Author 1:

• We updated the visit_occurrence.end_date, visit_occurrence.end_datetime, visit_detail.visit_detail_end_date, and visit_detail.visit_detail_end_datetime User Guide sections to direct users to set the visit_end_datetime to the date of the data extract when an inpatient visit is ongoing and the *.discharged_to_concept_id = 0.
• We updated the visit_occurrence.discharged_to_concept_id and visit_detail.discharged_to_concept_idETL Conventions sections to notify users it is assumed a Person returns home after a Visit, therefore, there is not a standard concept_id to represent 'home' and set the discharged_to_concept_id = 0

We should update this user guidance, as some things have changed.

Concept 32220 - Still Patient is non-standard, and the advice in the user guide for visit_end_date is to add this as the visit_type_concept_id, not discharge_concept_id.

For Inpatient Visits ongoing at the date of ETL, put date of processing the data into visit_end_datetime and visit_type_concept_id with 32220 “Still patient” to identify the visit as incomplete.

This is now conflicting with our conventions for type concepts to be standard and of class 'Type Concept'.

Author 3:

• THEMIS issue and still needs consensus on how patients till in the hospital should be handled.

There is ambiguity in the guidance. I am moving this to Needs More Work, so a convention can be discussed in the Themis WG.

[MelaniePhilofsky]

For inpatient stays, the current debate is to allow the visit_end_date to be NULL. The current CDM guidelines require a visit_end_date. @clairblacketer This is now a CDM issue.

[clairblacketer]

changing to proposal as it is suggesting to allow null end dates in visit_end_date, this needs to be figured out, either allow null end dates or make the concept standard.
