Pacemaker programmer usability varies significantly, impacting safe patient care. Design guidelines are needed to improve user interface consistency and functionality for clinicians.

Area of Science:

  • Biomedical Engineering
  • Human-Computer Interaction
  • Medical Device Usability

Background:

  • Clinicians perceive usability differences in pacemaker programmers.
  • Limited scientific literature exists on pacemaker programmer user interface usability.

Purpose of the Study:

  • To describe and quantify usability differences among pacemaker programmers from various manufacturers.
  • To identify specific usability issues and violations of general usability principles.

Main Methods:

  • Self-administered questionnaires completed by 42 pacemaker programmer users.
  • Independent heuristic evaluations by two usability experts.
  • Evaluation of programmers from seven different manufacturers (coded A-G).

Main Results:

  • Significant differences found in overall user satisfaction and ease of use (P < 0.0001).
  • Usability varied across display, controls, operation, and physical dimensions (P < 0.05).
  • Frequent usability principle violations identified, including reliance on recall and inconsistent controls.

Conclusions:

  • Pacemaker programmer interface designs often fail to meet user needs and established usability principles.
  • Inconsistent design impacts the safe and effective use of these critical medical devices.
  • Development of design guidelines for pacemaker programmers is recommended, focusing on critical controls.
