Radiologists moved to an environment in which they read digital images off of computer displays instead of film images off of light boxes. With film and light boxes they typically would read for about an hour (seated) and then take a break while the film librarian changed the images on the view box. With digital viewing off computers they tend to sit all day in front of the computers with far fewer breaks and opportunity to stand up and move around than with film. There is concern that this lack of activity not only contributes to back, shoulder and neck discomfort, but also contributes to increased fatigue which has been shown to impact reader performance. The goal of this study was to determine if there are differences in physiologic vital signs (heart rate and blood pressure) of radiologists as a function of whether they read images while seated or while standing up. Five subjects had their blood pressure and heart rate measured while seated and while standing reading cases in the normal clinical setting. For all three measures there was a statistically significant (p < 0.0001) difference between seated and standing measures with seated being lower than standing. The higher heart rate and blood pressure with standing suggests that the radiologists are more active in this position and thus potentially more attentive than while seated. This study will be followed up to determine impact on diagnostic performance of standing vs seated as well as subjective ratings of wakefulness and mood.
