Of Mice and Roentgen: Radiologist Satisfaction with a Non-conventional 13-Button Mouse-One Institution's Experience

Increasing radiologic exam volume and complexity necessitates leveraging advanced hardware solutions to optimize workflow efficiency. We evaluated radiologist satisfaction of a programmable 13-button non-conventional mouse compared to a conventional three-button mouse in daily interpretation workflow following a brief 2-day trial period. A prospective study was conducted with radiology staff and residents in a tertiary care center from 2015 to 2016. A survey was distributed prior to and after a tutorial and a 2-day non-conventional mouse trial period. The post-survey evaluated usage time, device settings, satisfaction, preferences, and perceived efficiency of both mice. Descriptive analyses, correlations, the Sign test, and the Wilcoxon signed-rank test were used to evaluate responses. Fifty-nine participants completed pre- and post-surveys. Several (41%, n = 24) had prior experience with a non-conventional mouse. Prior to the trial, one third of all participants (35.6%, n = 21) reported being satisfied or very satisfied with their conventional mouse. After spending an average of 9.8 h using the non-conventional mouse, there were no statistically significant changes in overall satisfaction with either conventional or non-conventional mice (p = 0.84 and p = 0.39, respectively). However, 76.3% (n = 45) agreed/somewhat agreed they preferred to use the non-conventional mouse in their daily workflow as opposed to the conventional mouse. The non-conventional mouse was also perceived as more efficient (66.1%, n = 39), required less time (62.7%, n = 37) and effort (74.6%, n = 44) to view images, allowed for easier manipulation of windows/images (76.3%, n = 45), and was more comfortable to use (78.0%, n = 46). Although there were no statistically significant shifts in overall satisfaction, participants reported a higher level of satisfaction, perceived efficiency, and preference for a non-conventional 13-button mouse compared to a conventional three-button mouse following a brief, 2-day trial period.
