Other research finds that the perception of malpractice risk drives such defensive medicine, including the use of diagnostic imaging, such as CT scans and MRIs.

I was interested in exploring what influenced the perception of this risk, hypothesizing that, for a physician, a report of an injury against one’s colleague might increase the perception of this risk and lead to an increase the use of diagnostic imaging.

The main finding is that when patients can’t sue they are treated about  5% less intensively.  Much of the effect appears to arise from fewer diagnostic tests.
