Objectives: To determine the number, nature and severity of usability issues radiologists encounter while using a commercially available radiology workstation in clinical practice, and to assess how well the results of a pre-deployment usability evaluation of this workstation generalize to clinical practice.

Methods: The usability evaluation consisted of semi-structured interviews and observations of twelve users using the workstation during their daily work. Usability issues and positive usability findings were documented. Each issue was given a severity rating and its root cause was determined.

Results: were compared to the results of a pre-deployment usability evaluation of the same workstation. Results: Ninety-two usability issues were identified, ranging from issues that cause minor frustration or delay, to issues that cause significant delays, prevent users from completing tasks, or even pose a potential threat to patient safety. The results of the pre-deployment usability evaluation had limited generalizability to clinical practice.

Conclusions: This study showed that radiologists encountered a large number and a wide variety of usability issues when using a commercially available radiology workstation in clinical practice. This underlines the need for effective usability engineering in radiology. Given the limitations of pre-deployment usability evaluation in radiology, which were confirmed by our finding that the results of a pre-deployment usability evaluation of this workstation had limited generalizability to clinical practice, it is vital that radiology workstation vendors devote significant resources to usability engineering efforts before deployment of their workstation, and to continue these efforts after the workstation is deployed in a hospital.
