About one in four cardiologists say they order tests to avoid being sued, a new study shows. The Center for Outcomes Research and Evaluation at Maine Medical Center in Portland surveyed nearly 600 doctors to determine, among other things, how non-medical issues influence their decisions to order invasive heart tests.

From the Associated Press:

Doctors who treated their patients aggressively were more likely to be influenced by malpractice worries or peer pressure than those who weren’t as aggressive, the study determined.

The study was published in the journal Circulation: Cardiovascular Quality and Outcomes.
