  • Article

This article describes features, enhancements, and bug fixes released in 2021 for the FHIR® service, DICOM® service, and MedTech service in Azure Health Data Services.

December 2021

Azure Health Data Services

Quota details for support requests

We updated the quota details for customer support requests with the latest information.

Local RBAC documentation updated

We updated the local RBAC documentation to clarify the use of the secondary tenant and the steps to disable it.

Deploy and configure Azure Health Data Services using scripts

We started the process of providing PowerShell, CLI scripts, and ARM templates to configure app registration and role assignments. Scripts for deploying Azure Health Data Services will be available after GA.

FHIR service

Bug fixes

  • Fixed: Added Publisher to CapabilityStatement.name. You can find the publisher in the capability statement at CapabilityStatement.name. See PR #2319.

  • Fixed: Log FhirOperation linked to anonymous calls to Request metrics. We weren't logging operations that didn’t require authentication. We extended the ability to get FhirOperation type in RequestMetrics for anonymous calls. See PR #2295 .

  • Fixed: 500 error when SearchParameter Code is null. Fixed an issue with SearchParameter if it had a null value for Code, the result was a 500 error. After the bug fix, it results in an InvalidResourceException like the other values do. See PR #2343.

  • Fixed: Returned BadRequestException with valid message when input JSON body is invalid. For invalid JSON body requests, the FHIR server was returning a 500 error. After the bug fix, the server returns a BadRequestException with a valid message instead of 500. See PR #2239.

  • Fixed: Handled SQL timeout issue. If the SQL Server timed out, PUT /resource{id} returned a 500 error. After the bug fix, we handle the 500 error and return a timeout exception with an operation outcome. See PR #2290.

November 2021

FHIR service

We expanded the patient-everything capabilities to process patient links PR #2305. For more information, see Patient-everything in FHIR.

Bug fixes

  • Fixed: Added software name and version to capability statement. In the capability statement, the software name distinguishes if you're using Azure API for FHIR or Azure Health Data Services. The software version specifies which open-source release package is live in the managed service. See PR #2294, PR #1778, and Issue #2241.

  • Fixed: Compress continuation tokens. Occasionally, the continuation token was too long to follow the next link in searches and resulted in a 404 error. To resolve the issue, we compressed the continuation token to ensure it stays below the size limit. See PR #2279 and Issue #2250.

  • Fixed: FHIR service autoscale. FHIR service autoscale provides optimized service scalability automatically to meet customer demands when they perform data transactions in consistent or various workloads. It's available in all regions where the FHIR service is supported.

  • Fixed: Resolved 500 error when the date was passed with a time zone. This fix addresses a 500 error when a date with a time zone was passed into a datetime field PR #2270.

  • Fixed: Resolved issue when posting a bundle with incorrect media type returned a 500 error. before the bug fix, when posting a search with a key that contains certain characters a 500 error was returned. See PR #2264 and Issue #2148.

DICOM service

Content-Type header includes transfer-syntax.

This enhancement enables the user to know which transfer syntax is used in case multiple accept headers are being supplied.
