Updating and Management

• Updates delivered every month/day
• Maintain a historical record of changed terms and
  concepts for version control
• Develop internal process to handle updates
• Deploy updates to end-users (hospitals,
  clinicians, etc.)
• Resolve local changes and conflicts
• Language engines and tools are required to
  facilitate these processes

5
Conflict Resolution

• Detect potential conflicts with the application
  of updates
• User adds terms, concepts, mappings
• Standard body adds same term, retires source of
  mapping, etc.
• Need tool to detect conflicts and to walk user
  through issues

6
Conclusion

• Updating terminologies involves greater
  challenges than initial use
• Tools and processes should be established for
  updating early in the process
