What must a link user share with a requestor to gain access to a requestor's release?

The correct choice is sharing User Context with a requestor to gain access to that requestor's release. User Context refers to the specific information about the user's role and permissions within the EpicCare Link system. By sharing this context, the link user effectively communicates their authority and relevance to accessing patient information or documentation.

This sharing mechanism is crucial because it helps maintain security and compliance by ensuring that only authorized individuals can gain access to sensitive data. User Context is specifically designed to facilitate appropriate access based on user roles, ensuring that the data exchange aligns with privacy regulations and institutional policies.

In contrast, the other options do not directly pertain to the requirement for accessing a requestor's release. Access Codes and Link Credentials may pertain to user authentication but do not specifically address what must be shared to gain access for a requestor. Patient Consent is important in the context of sharing patient information, but it does not replace the need for the User Context to establish access rights within the EpicCare Link system.
