Overview of FHIR Resource Searching in AWS HealthLake
Searching FHIR resources in AWS HealthLake AWS Documentation Searching FHIR
AWS provides documentation detailing how to use the FHIR search interaction to query resources within AWS HealthLake.
Summary
AWS HealthLake provides an interaction to search for FHIR resources within a data store based on specific filter criteria. This search can be performed using either GET or POST requests, with the use of POST recommended when handling Personally Identifiable Information (PII) or Protected Health Information (PHI), as this ensures encryption in transit.
Key Players
Details
AWS HealthLake offers a dedicated interaction for searching FHIR resources within its data store. Users can perform searches based on various filter criteria using either GET or POST requests. A key technical recommendation is the use of POST requests when dealing with sensitive Personally Identifiable Information (PII) or Protected Health Information (PHI), because these types of data are included in the request body and are encrypted during transit, enhancing security. It is noted that this search interaction adheres to the HL7 FHIR R4 standard for health care data exchange. Due to its nature as a representation of an HL7 FHIR service, it is not directly available through AWS CLI or AWS SDKs. Furthermore, HealthLake supports only a subset of the full FHIR R4 search parameters, requiring users to consult specific documentation for details. The guide also covers advanced topics such as different methods (GET vs POST), Consistency Levels, and Idempotency/Concurrency, making it a detailed technical reference for implementing FHIR searches.
