AWS documented the lifecycle and state management of FHIR Subscriptions within the AWS HealthLake service.
Summary
AWS HealthLake provides a 'Subscription' feature, based on FHIR standards, to monitor events within a data store and send notifications when specific criteria are met. This mechanism requires managing an entire lifecycle, from topic creation and subscription setup to activation, error handling, and deactivation.
Key Players
Details
AWS HealthLake enables event monitoring of medical data stores compliant with the FHIR standard. This functionality is implemented as a 'Subscription,' requiring users to first create a `SubscriptionTopic` defining its status, followed by creating the specific reading configuration, the `Subscription`. When both the topic and subscription are active, HealthLake monitors events occurring within the data store. Upon matching an event, notifications are sent to a pre-configured endpoint. Technically, this process utilizes FHIR backport structures (e.g., `backport-subscription`, `backport-filter-criteria`) for status management and error handling. The subscription lifecycle can be controlled by setting an end date or explicitly deleting the resource. This capability is crucial for healthcare organizations needing to detect specific patient events (e.g., Encounter?subject=Patient/<patient id>) in real time, facilitating system integration and building data-driven medical processes or alert systems.
