| 1 | A Visit Occurrence is recorded for each engagement of a patient with the healthcare system. It reflects the constellation of such engagement, not an actual concrete healthcare institution.|
| 2 | Valid Visit Concepts belong to the 'Visit' domain.|
| 3 | Standard Visit Concepts are defined hierarchically, rolling up into 12 top concepts:
* 581478 "Ambulance Visit"
* 38004193 "Case Management Visit"
* 262 "Emergency Room and Inpatient Visit"
* 9203 "Emergency Room Visit"
* 581476 "Home Visit"
* 38004311 "Inpatient Hospice"
* 9201 "Inpatient Visit"
* 32036 "Laboratory Visit"
* 42898160 "Non-hospital institution Visit
* 9202 "Outpatient Visit"
Note that there is a combined "ER and Inpatient Visit" because it is close to impossible to separate the two in many EHR system. |

| 4 | Handling of death: Visits are not used to indicate a patient's death. If the source data contains death information in a visit context the date should be derived (admission or discharge) and placed into the death_datetime field of the PERSON table. For details, see [there](https://github.com/OHDSI/CommonDataModel/wiki/VISIT_OCCURRENCE/_edit).|
| 5 | Source Concepts from a number of vocabularies are mapped into Standard Visit Concepts. Visit Concepts form a hierarchy. Therefore, the most detailed Visit Concept should be picked or mapped to during ETL. It is no longer necessary to infer a top Concept from the hierarchy. |
| 6 | At any one day, there could be more than one visit. |
