Second, VR systems are usually sensitive to hardware configurations, so you should maintain as consistent a hardware configuration as possible. The sound system is most important, including the microphone and sound card. Don't expect one radiologist to use multiple stations if the stations use different hardware configurations, because hardware configurations can dramatically affect VR performance, and this is frustrating for physicians. Third, proper VR implementation requires that users are trained to use the system. Radiology operations place a high demand on people's time, so it can be difficult to ensure that users are available for an adequate amount of time to receive training.
Users often expect to see instant results with perfectly transcribed reports.
Expectations must be properly set so that users realize the systems require time to build a history of the user's word context and pronunciation of problematic words. Typically, VR does well in areas with a high degree of structured and repetitive dictation. Areas with a high percentage of negative reports are favorable, as they allow more use of macros and templates, with standardized dictation. Dictation by the same people in the same area is also favorable, since it minimizes environmental differences. The trend in PACS is toward greater integration of the radiologist's workflow.
