Doctors poor at estimating benefits and harms

Doctors are not much better than their patients when it comes to estimating the benefits and harms of treatment, screening and tests, say Australian researchers.

Their systematic review of 48 studies with over 13,000 (mostly) doctors found most participants could only correctly estimate benefits for three of 28 outcomes assessed. It was a similar story for harms, with the majority of doctors correctly estimating harm for 9 of the 69 outcomes.
