The clinical efficacy and physicians' assessment of a medical image management system (MIMS) for chest images that involved the medical intensive care unit (MICU) and the radiology department were evaluated. A token-passing fiber-optic network was implemented to connect display stations in the MICU and in the chest reading area in the radiology department with a laser film digitizer and an archiving system. To study the clinical efficacy of this system, blocks of 8 weeks during which portable chest images were digitized and immediately made available in the MICU were alternated with blocks of 8 weeks during which film images only were available. Approximately 3000 portable chest examinations were tracked; patients were entered into the study at a rate of 65 per month. Data on time intervals associated with the examination process were collected from MICU physicians, radiologists, radiographers, and film librarians. The time from the completion of an examination to the time an action was taken that was based on radiographic findings showed significant reductions during the digital periods for certain actions. For example, the time to begin drug therapy decreased from a mean of 4.7 hr when films were viewed to a mean of 3.3 hr when digital images were viewed. In conclusion, if prompt action by the MICU physician improves a patient's outcome, a positive effect on patient care will result from the immediate availability of radiographic images.
