Substitutable Medical Apps in i2b2

As part of the ONC's Strategic Health IT Advanced Research Projects (SHARP) program and the Substitutable Medical Apps Reusable Technologies (SMART) initiativeproject, a we have SMART-enabled i2b2 cell is being developed to expose a common API for SMART-applications to the i2b2 platform so that substitutable SMART applications (apps) can interact with health data within the i2b2 analytics platform.

The SMART i2b2 cell currently exposes a "Get Medications" function that returns the entire graph of stored medications in RDF/XML format for a single patient record via a REST call.

Get Medications

GET http://i2b2_server/records/{record id}/medications/

...

GET http://i2b2_server/records/{record id}/demographics/

will return the demographic information in RDF/XML for a specific patient based on the record_id passed

Get Problems

GET http://i2b2_server/records/{record id}/problems/

will return a list of problems in RDF/XML for a specific patient based on the record_id passed

New: "Get Allergies" has been added to the SMArt i2b2 cell per current SMArt API specifications

Get Allergies

GET http://i2b2_server/records/{record id}/allergies/

will return a list of allergies in RDF/XML for a specific patient based on the record_id passed

The SMART Dashboard is a new i2b2 web client plugin that allows for the embedding of SMART applications directly in the web query tool. As shown in the screenshot below, an external SMART app has been embedded directly in the i2b2 web query tool and has access to i2b2 patient data via the SMART connect model described at www.smartplatforms.org

. We have created a new i2b2 cell ('the SMART cell') that exposes the SMART API for various types of data including medications, problems, demographics, lab results, vital signs, notes, etc. These functions return a common RDF/XML output in which SMART apps understand.
