Post-deployment usability evaluation of a radiology workstation.

Area of Science:

• Medical Informatics
• Human-Computer Interaction
• Radiology

Background:

• Usability of radiology workstations is critical for efficient and safe patient care.
• Pre-deployment usability evaluations aim to identify and mitigate issues before clinical use.

Purpose of the Study:

• To identify and categorize usability issues encountered by radiologists using a commercial radiology workstation in practice.
• To assess the generalizability of pre-deployment usability evaluation findings to real-world clinical settings.

Main Methods:

• Conducted semi-structured interviews and direct observations of twelve radiologists during their daily work.
• Documented usability issues, their severity, and root causes, comparing findings to a prior pre-deployment evaluation.

Main Results:

• Identified 92 usability issues, varying in severity from minor frustrations to potential patient safety threats.
• Found that pre-deployment usability evaluation results had limited generalizability to actual clinical practice.

Conclusions:

• Radiologists face a significant number and range of usability challenges with current radiology workstations.
• Effective usability engineering, both pre- and post-deployment, is crucial for radiology workstation vendors to ensure optimal clinical performance and patient safety.
