The linked report seems almost useless -- it doesn't say anything about an error rate or a sample size, so it's a mystery whether 9 out of 20 systems “fabricated information and made suggestions to patients' treatment plans” ten out of ten times, or one out of a thousand times.
If we just postulate that the systems have a high error rate, I wonder why they are being adopted. They seem extremely easy to test, so I don't see why doctors or hospitals or governments should be getting tricked into buying them if they suck.
