Today during the CDM working group call we started discussing the VISIT_OCCURRENCE and VISIT_DETAIL tables. @DTorok questioned the necessity of the CARE_SITE_ID in the VISIT_DETAIL table since records in the VISIT_DETAIL table roll up to records in the VISIT_OCCURRENCE table and therefore should always be related to the CARE_SITE_ID in the parent Visit record. We dug a little deeper and read our new and improved documentation on the CARE_SITE table where we realized that Care Sites can be physical locations like hospitals but they can also be wards within the hospital like ICU or Med-Surg. Herein lies the core of our question:
Should movements between hospital wards be tracked using
- The CARE_SITE_ID in the VISIT_DETAIL table OR
- The VISIT_DETAIL_CONCEPT_ID in the VISIT_DETAIL table
@MPhilofsky have you all in the EHR group decided how to handle this issue?
