cityEHR is an open source (LGPL) electronic health records system designed to support patient-centred, shared care and reuse of data for clinical studies.

All clinical data are held using open standards such as HL7 CDA, ISO-13606 and XML.

The system runs as an enterprise-scale, web-based application, configured entirely through an information model created by clinical users themselves using spreadsheets and other familiar tools.
