EHRGen is an EHR framework based on openEHR that aims to provide a fast way to create and modify openEHR-based EMR applications with minimal effort. It generates the GUI, database schema, and basic business logic from openEHR archetypes and terminology to create customized EMR systems for various specialties and departments while keeping clinical knowledge separate from the application code. Security features include role-based authorization and permission controls at the clinical domain level.

- 2. The EHR environment • EMR – Clinical recording applications (input) – Local records – Customized applications for: • specialties (e.g. cardiology) • departments (e.g. emergency) • EHR – Shared records (search, output) • Many medical specialties for the same patient • Demographic – Persons, organizations & roles
- 3. The EHR environment • Terminology Server – terminologies, classifications, codes • Content Server – archetypes & templates • Rules Server (CDS & epidemiology) – alerts, recommendations, reminders, notifications • Process Server – BPM, workflow mgt., task mgt. • CPOE – order management (send, authorization, receive)
- 5. EHRGen coverage • Doesn’t cover rules XML Rule Engine
- 6. EHRGen objectives • Provide a fast way to create & modify openEHR-based EMR applications • Provide adaptable systems deployable in any healthcare environment with minimum effort • Lower costs, minimize time to market, formalization of the development process, long term maintainability, …
- 7. EHRGen features • One framework to create many EMR systems • Clinical knowledge is not hardcoded in the app • Changes in the clinical record structure without changing the source code • Local or remote demographic repository • Security: – role based user authorization – authorization permits by clinical domain • Supports versioned archetypes and UI templates • Technologies: Java/Groovy/Grails/MySQL
- 8. EHRGen functionalities • GUI autogeneration: – from archetypes, UI templates and terminology – Web, I18N • DB schema autogeneration: – from openEHR domain classes • Generic business logic: – input data validation (using archetypes) – data binding for persistence • creates compositions from input data • Semantic querying & data aggregations (prototype)
