Details
AWS HealthLake provides comprehensive search functionality for FHIR Subscriptions and SubscriptionTopic resources. A key feature is the availability of extended search options tailored for specific use cases, beyond standard parameters. For searching subscriptions (Subscription), in addition to basic fields like `contact` or `status` adhering to the R4 core specification, advanced extension parameters are available. These include `payload-type` (e.g., full-resource) for specifying payload format, and a dedicated `topic` parameter for filtering by specific topics. Furthermore, proprietary extended parameters allow searching using detailed criteria such as custom channel types or filter criteria. For SubscriptionTopic resources, detailed filtering is possible from multiple angles, including date (`date`), identifiers (`identifier`), resource type (`resource`), status (`status`), and title (`title`). These capabilities provide a technical foundation that supports the construction of event notification and topic-based monitoring systems in healthcare data integration, enabling developers to efficiently discover data matching specific conditions.
