Summary

The entity_hospitals table contains information on the entities that are considered hospitals. It contains details on the hospital and its operating specifications. The entity_id field links to the entities table, having the same id existing in both tables and acting as a key.

The entity_hospitals table also links to entity_hospital_overrides, entity_hospital_attributes, relationship_ascs_hospitals

Notes

2010-05-26

Updated the `aha_service_id` field's type from VARCHAR(3) to VARCHAR(255) because the field was not large enough to store all pertinent data. This was discussed with jmking before implementation.
