CHOIR: Design
CHOIR Goals
To develop, implement and expand an open source, open standard and free health and treatment registry platform, a platform that will be used to collect outcomes data on large numbers of patients suffering from chronic pain. The platform can eventually be expanded to include other health conditions. The platform should support: clinical decision support at the point of care, comparative effectiveness research, longitudinal outcomes research, and large simple trial designs. For some of our accomplishments, please see Clinical Features of CHOIR, and Research Features of CHOIR.
CHOIR Design Philosophy
- Open standards-based
- Open source-based
- Open application programming interface (API)
- Portable
- Extensible feature set & customizable
- Rapid definition & deployment for new disease areas
CHOIR Infrastructure
Current design of CHOIR consist of a secure web server that hosts the web application. Patient and clinician users access the web app via web browsers on desktop, tablet, or mobile phone. Design of user interface is made responsive to the form factor with custom jQuery mobile-based code integrated with Google Web Toolkit.
The web application interacts via API with more computationally intensive algorithm engines, for instance the CHOIR CAT, our own multi-feature next generation computerized adaptive testing engine for NIH PROMIS.
Internally, the platform is designed to be flexible and customizable, to accommodate new surveys or clinical conditions, such as Headache CHOIR, Ortho CHOIR, or GI CHOIR. Externally, the platform integrates with EMR via API for scheduling (complete and operational) and for data interchange (funded work, on-going).
