Area of Science:

  • Medical Informatics
  • Clinical Decision Support Systems
  • Family Medicine

Background:

  • Traditional patient intake can be time-consuming.
  • Physician focus can be fragmented during patient interviews.

Purpose of the Study:

  • To introduce a novel knowledge-based, patient-driven expert system for screening.
  • To evaluate the system's impact on physician productivity and patient focus in an outpatient family practice setting.

Main Methods:

  • A knowledge-based expert system was implemented for 10,000 outpatient family practice visits.
  • Patients completed a laptop-based, response-driven questionnaire.
  • The system dynamically adjusted questioning based on patient answers.
  • Validated self-rating scales were administered when indicated.
  • Patient data was succinctly presented to the physician prior to the interview.

Main Results:

  • The system collected subjective patient complaints directly and efficiently.
  • Physicians could rapidly review patient data and graphical scales for a quick clinical impression.
  • The system facilitated a focused physician-patient interaction.

Conclusions:

  • The patient-driven expert system significantly enhances physician productivity.
  • This approach improves focus on the presenting medical problem.
  • The system demonstrates potential for widespread application in clinical practice.
