SMART (Substitutable Medical Apps, Reusable Technologies) is one of four Strategic Health IT Advanced Research Projects (SHARP) funded by the Office of the National Coordinator for Health Information Technology. SMART provides a unified mechanism for diverse applications to interact with medical record data. SMART Apps built against the SMART API can be embedded within any SMART Container.

A SMART Container is, most often, an Electronic Medical Record (EMR) system used by physicians but might also be a Personal Health Record (PHR) such as Indivo used by patients, a data-analytics platform such as i2b2 used by researchers or a clinical data repository system for HIEs (Health Information Exchange) such as Mirth Results. A partial list of the systems and companies that have already implemented SMART can be found here.

USGovXML has created rxInfo: A suite of SMART Apps. The rxInfo suite of SMART apps are available ... here .... If you have implemented or are in the process of implementing a SMART container and need SMART apps to test your implementation, we would like to hear from you! Send us a link to your container’s sandbox when you contact us.

Are you a C#/.Net developer? Do you want to create a SMART app? If the answer to both questions is yes, has created a sample SMART web app that is available as a Visual Studio 2008 project. The project can be downloaded from: Make sure you read the included readme.txt file for details.
