The Open Record for CAre (ORCA) system effectively supports structured data collection in medicine. Balancing interface flexibility with data retrieval proved challenging when expanding to physical examination data.

Area of Science:

  • Medical Informatics
  • Clinical Data Management
  • Human-Computer Interaction

Background:

  • Clinician-facing systems for structured data collection require flexible interfaces.
  • The Open Record for CAre (ORCA) system utilizes a generic model for knowledge-based data entry across medical domains.

Purpose of the Study:

  • To expand the ORCA knowledge base to include the domain of Physical Examination.
  • To evaluate the expressiveness of the ORCA model for this new domain.
  • To analyze the trade-offs between interface flexibility and data retrieval reliability.

Main Methods:

  • Expansion of the ORCA knowledge base to encompass Physical Examination data.
  • Utilizing the generic model for knowledge-based structured data entry.
  • Illustrating the impact of flexibility vs. retrieval trade-offs with specific examples.

Main Results:

  • The ORCA model demonstrated adequate expressiveness for incorporating Physical Examination data.
  • Balancing interface flexibility with reliable data retrieval presented significant challenges.
  • Specific examples highlight the effects of this trade-off on the modeling process.

Conclusions:

  • The ORCA system's generic model is adaptable to new medical domains like Physical Examination.
  • Careful consideration of the flexibility-retrieval balance is crucial for system design.
  • Future research should focus on optimizing this balance for enhanced clinical data collection.
