Personal digital assistants (PDAs) are more effective than tablet PCs for retrieving drug information, showing higher success rates and faster task completion. This study highlights PDAs as superior tools for accessing pharmaceutical data.

Area of Science:

  • Health Informatics
  • Human-Computer Interaction
  • Pharmaceutical Sciences

Background:

  • Accessing drug information is crucial for healthcare professionals.
  • Evaluating the usability of handheld devices for information retrieval is essential.

Purpose of the Study:

  • To compare the usability of personal digital assistants (PDAs) and tablet PCs for retrieving drug information.

Main Methods:

  • A randomized crossover study involving 34 pharmacy and medicine students.
  • Participants used both PDA and tablet PC to answer drug information questions and perform qualitative analysis.
  • Evaluation criteria included success rates, time-on-task, and number of clicks.

Main Results:

  • No significant demographic differences between study groups.

  • PDAs showed significantly higher success rates for one question and were faster for seven questions.
  • PDAs generated fewer clicks for three questions and were qualitatively preferred for clarity, navigability, and usefulness.

    • Conclusions:

    • PDAs are quantitatively and qualitatively more effective than tablet PCs for drug information retrieval among students.
    • PDAs offer a superior user experience for accessing pharmaceutical data.
