OSCAR is open-source Electronic Medical Record (EMR) software that was first developed at McMaster University by Dr. David Chan. It is continuously enriched by contributions from OSCAR users and the Charter OSCAR Service Providers that support them. OSCAR has been certified by OntarioMD, and verified as IHE compliant, achievements made possible by the creation and success of OSCAR EMR’s ISO 13485:2003 certified Quality Management System.

It is our belief that technology, developed and grown through an open, collaborative and community-based approach, will provide the best results for patients, providers and the health care system.

OSCAR 15.0 has been approved by OntarioMD to replace OSCAR 12.1.2 as OSCAR EMR’s Certified Offering under Ontario EMR Specification 4.1A, effective February 16, 2016.  OntarioMD has also confirmed that all security and privacy criteria required for release have been met as identified in a Threat Risk Assessment (TRA) that was undertaken by an independent third-party.  In fact, OSCAR 15.0 has passed an unparalleled level of review and validation for security, privacy and other functionality.
