New Report Available: Push Button Health: Advancing SMART/HL7 Bulk Data Export/FLAT FHIR

The universal health data application programming interfaces called for in the 21st Century Cures Act present an opportunity to create the learning healthcare system that has been long envisioned. A learning healthcare system must be able to do more than conduct individual queries on one patient; it requires the ability to aggregate and analyze data at a population level. Activities such as managing population health, delivering value-based care, and conducting discovery science requires access to large population data sets. Population level data combined with new technologies such as machine learning and AI has extraordinary potential to improve the health and lives of Americans.

To address this need, the SMART team and HL7 have jointly developed the SMART/HL7 Bulk Data/Flat FHIR standard and associated tools.

Building on the momentum our 2017 Population Level Data Export / FLAT FHIR Meeting, the Office of the National Coordinator for Health Information Technology asked the Computational Health Informatics Program (CHIP) and SMART Health IT team to host a second meeting to measure interval progress on use and uptake of the SMART/HL7 Bulk Data/Flat FHIR standard and tools, understand where the rough edges are, explore federal use cases, and drive toward effective regulation.

The 2019 SMART Flat FHIR / Bulk Data meeting was held on November 6th at the Harvard Medical School Countway Library. Sixty stakeholders from across the healthcare ecosystem gathered to talk about bulk data use cases and experience, and plan next steps for the standard and its use. 

Key Takeaways:

  • Demand for standardized bulk data export in the Flat FHIR format is growing rapidly. 
    • Within eight months of the 2017 meeting, the Centers for Medicare and Medicaid Services (CMS) were already using the standard in pilots to provision data to ACOs. 
    • An astounding 105,000 providers have requested access to Flat FHIR data via the CMS Data at Point of Care Project.
  • The substantial efforts, via the Argonaut project, to implement the SMART on FHIR API advances us significantly toward implementing the bulk data API at scale. Notably, the Argonaut process was one year long and can serve as a yardstick for the length of time required for implementation of bulk data capabilities. 
  • More than 20 health systems and health plans have committed to move the HL7 balloted standard into real-world testing. 
  • The community has access to a suite of free and open-source products to facilitate FHIR bulk data implementation, including the SMART reference implementation, SMART sample client, and the SMART bulk data testing tool to verify server compliance.

Push Button Population Health Data: Extending the HL7 FHIR Standard to Support Bulk Data Export

Activities such as managing population health, delivering value-based care, and conducting discovery science require access to large population data sets. The existing FHIR and SMART APIs work well for accessing small amounts of data, but large exports perform poorly, requiring an impractical number of API requests to be issued serially. By adding asynchronous primitives to FHIR and defining an export operation, the Bulk Data API enables secure integration of third-party, externally-hosted applications into diverse EHR and data warehouse environments.

On behalf of the ONC, The Boston Children’s Hospital Computational Health Informatics Program and SMART hosted a meeting in December 2017 to discuss standardizing bulk data exports from EHR systems and data warehouse environments. This meeting brought together key stakeholders from across health care, including the Director of the Office of the National Coordinator for Health Information Technology (ONC) and other members of the ONC staff, as well as representatives from payers, health systems, EHR vendors, and other health technology innovators.

New Report On Connected Apps in Healthcare

In an evaluation developed in partnership with SMART and funded by the Office of the National Coordinator for Health Information Technology (ONC), KLAS Research spoke with clinical leaders at nearly 50 healthcare organizations about how they select and use clinical apps today, what they would like to see in the future, and the concerns they have around adopting apps.

Findings include:

  • Around half of the healthcare organizations interviewed use apps at the point-of-care.
  • Looking forward, many providers are interested in purchasing or developing apps around patient engagement, followed by EHR data visualization, diagnostic tools and decision support tools.
  • Usability is the most important factor healthcare organizations consider when purchasing an app, followed by cost, clinical impact and integration with existing systems.
  • Pilot programs and demos represent providers preferred way to evaluate apps, with peer recommendations, web content and video demonstrations also being popular.
  • Privacy and security is by far the biggest concern around adopting apps, although app credibility, concerns regarding ongoing maintenance, and the need for integration with existing systems are also high on the list.

The role of apps in healthcare is growing, with many organizations looking to third-party vendors to supply niche solutions that improve patient care and organizational efficiency.

Increasing adoption of the SMART and FHIR application programming interfaces (APIs) by EHR vendors and health systems is streamlining the process of connecting these apps to clinical systems, and strong regulatory support requiring APIs in certified health IT is expected to continue driving this trend. With app discovery tools, such as the SMART App Gallery, making it easier for healthcare providers to find and evaluate apps, there is a bright future for connected apps in healthcare.

21st Century Cures Act makes APIs in EHRs the law

curesactcongress21st-century

One aim of the 21st Century Cures Act recently passed by Congress is to make digital health data more accessible, emphasizing the use of APIs in healthcare to increase EHR interoperability and improve patient records matching. Aligning closely with the SMART Health IT focus on creating a app ecosystem for healthcare, the act states that a year from now, open APIs will be necessary for EHR system certification.


“… that the entity has in place data sharing programs or capabilities based on common data elements through such mechanisms as application programming interfaces without the requirement for vendor-specific interfaces;

[…] publish application programming interfaces and associated documentation, with respect to health information within such records, for search and indexing, semantic harmonization and vocabulary translation, and user interface applications; and

[…] demonstrate to the satisfaction of the Secretary that health information from such records are able to be exchanged, accessed, and used through the use of application programming interfaces without special effort, as authorized under applicable law.”
