Paper Abstract

As part of a study of the use of a PACS workstation compared to film in a Medical Intensive Care Unit, logs of workstation activity were maintained. The software for the workstation kept track of the type of user (i.e., intern, resident, fellow, or attending physician) and also of the workstation image manipulation functions used. The functions logged were: no operation, brightness/contrast adjustment, invert video, zoom, and high resolution display (this last function resulted in the display of the full 2 K X 2 K image rather than the usual subsampled 1 K X 1 K image. Associated data collection allows us to obtain the diagnostic category of the examination being viewed (e.g., location of tubes and lines, rule out: pneumonia, congestive heart failure, pneumothorax, and pleural effusion). The diagnostic categories and user type were then correlated with the use of workstation functions during viewing of images. In general, there was an inverse relationship between the level of training and the number of workstation uses. About two-thirds of the time, there was no image manipulation operation performed. Adjustment of brightness/contrast had the highest percentage of use overall, followed by zoom, video invert, and high resolution display.
