Students found tapping faster than typing for recording patient diagnoses on handheld devices. This electronic student encounter log (ESEL) shows tapping

Area of Science:

  • Medical Informatics
  • Human-Computer Interaction
  • Medical Education Technology

Background:

  • Accurate patient diagnosis recording is crucial for medical education.
  • Data entry on handheld computers presents challenges, impacting efficiency.
  • Existing software often uses typing or complex tapping interfaces.

Purpose of the Study:

  • To develop and evaluate an Electronic Student Encounter Log (ESEL) for recording patient diagnoses.
  • To compare the efficiency of tapping versus typing interfaces for data entry.
  • To assess student usage patterns in ambulatory care settings.

Main Methods:

  • Development of ESEL with both tapping and typing interfaces.
  • Tapping interface organized diagnoses in a tree structure for quick access.

  • Typing interface mimicked reference software with search functionality.
  • Analysis of 62 students' ESEL usage data.

    • Main Results:

    • Students predominantly used the tapping interface over the typing interface.
    • Data recording was significantly faster using the tapping method.
    • The tapping interface made 983 diagnoses visible within 2 taps.
    • The typing interface offered a list of 1332 common problems.

    Conclusions:

    • The tapping interface of ESEL proved more efficient for student data entry.
    • Tapping interfaces may be a viable alternative for handheld data capture.
    • Further research on accuracy is recommended for wider adoption.
