A new study finds that doctors need to do a better job of communicating with parents of sick children who participate in medical research.
Doctor Eric Kodish of the Rainbow Babies and Children's Hospital in Cleveland is the study's lead author. He says parents often do not understand that their children are selected randomly for a specific treatment.
According to the study, randomization was explained to most parents who were studied, but half of them did not understand the concept.
Kodish says this shows a need for better communication between doctors and parents to make sure that parents fully understand the process before they agree to let their kids become research subjects.
The study appears in tomorrow's Journal of the American Medical Association.
