HealthLake is a HIPAA-eligible service that helps organizations leverage unstructured health information. It uses the Fast Healthcare Interoperability Resources (FHIR) industry standard to format data and enable organizations to move it from on-premise systems to a secure, cloud-based data lake. It then uses machine learning to analyze medical terminology and clinical data, and it provides standardized labels for data that makes it easier to search and analyze. With all that accomplished, AWS customers can then use analytics and machine learning to analyze the newly-structured data.  Customers using HealthLake so far include Rush University Medical Center, which used HealthLake in its Covid-19 response. Cortica, which provides healthcare services to children with autism and other brain conditions, has used it for deeper insight into the care progression of its patients.
