Paper Abstract

The Integrated Radiological Information System (IRIS) supports the capture and distribution of digitized x-ray images and voice reports in the form of " electronic" patient folders which can be accessed at physician workstations throughout the hospital. Each workstation has an image screen to display documents and x-ray images a control screen to access patient folders and a hands-free telephone to dictate and play back reports and enable consultation between radiologist and clinician workstations. A seven week clinical trial of IRIS was conducted at the Ottawa Civic Hospital during April and May 1989. The system operated to process cases from the Department of Emergency Medicine weekday afternoons. Observers recorded for each case how radiologists used the system. After the trial radiologists participated in an extensive debriefing interview during which they were asked to complete a number of rating scales addressing the following issues: 1) willingness to diagnose by tissue type and by type of pathology 2) seriousness of problems due to system limitations 3) the perceived usefulness of enhancement capabilities and measurement tools. Overall the system was found to be acceptable by the radiologists. There was some concern about diagnosis in soft tissue regions. Most of the system features were regarded as acceptable but there were areas which needed improvement. The suggested improvements are described where applicable. The enhancement facilities and the means of using the facilities were acceptable overall. 426 /
