BACKGROUND Broad-based electronic health information exchange (HIE), in which patients' clinical data follow them between care delivery settings, is expected to produce large quality gains and cost savings. Although these benefits are assumed to result from reducing redundant care, there is limited supporting empirical evidence. OBJECTIVE To evaluate whether HIE adoption is associated with decreases in repeat imaging in emergency departments (EDs). DATA SOURCE/STUDY SETTING ED discharge… CONTINUE READING

Within 3 common types of imaging tests [ computed tomography ( CT ) , ultrasound , and chest x - ray ) , we defined a repeat image for a given patient as the same study in the same body region performed within 30 days at unaffiliated EDs .

In our sample there were 20,139 repeat CTs ( representing 14.7% of those cases with CT in the index visit ) , 13,060 repeat ultrasounds ( 20.7% of ultrasound cases ) , and 29,703 repeat chest x - rays ( 19.5% of x - ray cases ) .
