Effect of a digital imaging network on physician behavior in an intensive care unit.
This study examined the effect of a medical image management network on the behavior of physicians working in a medial intensive care unit (MICU). For 1 year, 8-week periods during which chest radiographs were digitized and made available to MICU physicians on a digital display console were alternated with 8-week periods during which only film images were available. Clinical efficacy during the periods was compared by measuring the time between completion of imaging examinations and initiation of specific clinical actions such as placement and positioning of tubes. Results indicate that the time required to take some clinical actions decreased with the immediate availability of images on the digital display console. Established procedures for obtaining radiologic information were altered by the digital imaging network. The time at which physicians viewed images changed, and consultations between MICU staff and radiologists decreased. These results indicate that behavior patterns are altered when a new technology replaces an existing one. Optimal use of this technology may require changes in the logistics of clinical practice.
