| 8 | One visit may involve multiple Care Sites, in which case the ETL must specify how a single CARE_SITE_ID is selected or leave the CARE_SITE_ID field null. |
| 9 | The discharge disposition (discharge_to_concept_id) should be filled with Visit concept. Death is no longer captured here. In addition to the Standard Visit Concepts the special concept 44814693 "Absent without leave" and 4021968 "Patient self-discharge against medical advice" can be used. |
| 10 | The preceding_visit_id can be used to link a visit immediately preceding the current visit. Note this is not symmetrical, and there is no such thing as a "following_visit_id". |
-| 11 | Visit end dates are mandatory. If end dates are not provided in the source there are three ways in which to derive them:
- Outpatient Visit: visit_end_datetime = visit_start_datetime
- Emergency Room Visit: visit_end_datetime = visit_start_datetime
- Inpatient Visit: Usually there is information about discharge. If not, you should be able to derive the end date from the sudden decline of activity or from the absence of inpatient procedures/drugs.
- Long Term Care Visits: Particularly for claims data, if end dates are not provided assume the visit is for the duration of month that it occurs.
- 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.
