Monitoring radiation doses from diagnostic Computed Tomography (CT) examinations is essential to maintaining patient safety and ensuring that technologists are using optimal scan parameters. To receive accreditation from The Joint Commission, facilities are required to track incidents where radiation dose indices from CT exams exceed their expected dose index; however, there is no universal definition as to what constitutes an expected dose index. This research focuses on creating a standard of practice for setting CT dose thresholds that maximize the sensitivity and specificity of tracking, ensuring appropriate patient safety without creating an excessive number of false-positive notifications.
