FHIR R4 $confirm-attribution-list Operation Specification for HealthLake

Details

This technical guide details the '$confirm-attribution-list' endpoint based on FHIR R4 specifications for the AWS HealthLake environment. The operation serves to finalize the Attribution List (ATR) of a Group resource by removing inactive members and changing the status to 'final'. This functionality is part of the FHIR IG 2.1.0. The API uses the POST [base]/Group/[id]/$confirm-attribution-list endpoint, requiring no parameters. A successful call returns HTTP 201 with a confirmation message, and subsequently updates the Group resource status to 'final'. Execution requires clients to possess appropriate SMART Scope privileges for reading group and related attribution resources, and crucially, writing permissions to modify the group resource. The document also specifies error handling for invalid requests (400) or non-existent group resources (404). This feature is a critical technical specification for managing the lifecycle of group attributes in healthcare data interoperability.
