The Emergency Department is a Big Contributor to Overutilization: CT Ordering Rates Vary by More Than 100%
As the second in a series of graphical stories that highlight imaging’s role in overutilization, our latest infographic focuses on the impact of variation in CT utilization across emergency medicine clinicians.
The graphic illustrates more than 100 percent variation in CT utilization in 58 hospital emergency departments (EDs) across the United States over the last two years. CTs accounted for 19 percent - 40 percent of all imaging ordered at the facilities we observed, with a median of 28.5 percent. Our analysis indicates that clinician behavior is a significant contributor to this variation. A view into one hospital’s ED shows the highest physician utilizers order CTs at four times the rate of the lowest utilizers.
