SyntheticMass (syntheticmass.mitre.org) is model of all 7 million residents of the state of Massachusetts, with artificial health records for the fictional residents. This establishes a risk-free environment for:

• Data visualization
• Risk stratification
• Care management
• Clinical decision support
• Patient Reported data integration
• Evaluation of new treatment models
• Privacy and consent models
• Security and authorization models
• Third-party app development

SyntheticMass will provide a sandbox for Health IT developers, researchers and clinicians interested in prototyping new healthcare solutions. It enables this through:

• Realistic data for fictional patients
• Data that is free of protected health information (PHI) and personally identifiable information (PII) constraints
• Datasets updated over time based on clinical healthcare models and epidemiological models of population health.

###The MITRE Corporation The MITRE Corporation is a not-for-profit organization working in the public interest that operates federally funded research and development centers to provide innovative solutions to national problems.
