Two intensive care units, the MICU (Medical Intensive Care Unit) and the SICU (Surgical Intensive Care Unit) were studied. The results demonstrated that clinicians in the SICU (with digital viewing capability) were 9'/2 times more likely to view exam results within an hour than those in the MICU (without digital display) were to receive any kind of notification of the exam results within an hour. Some of the differences observed between the two units were attributed to the differences in operation. In an effort to determine the portion of the differences attributable to differences in operation of the two units, another study was performed in the MICU after a digital viewing station was installed. These results were compared with the results obtained before the digital viewing stations were installed. Results have shown that there is no statistical difference in the times within which the exams are viewed for the two cases.
