Radiation Therapy Mistakes Cost Lives

jmtpi recommends a long NY Times investigative report about how powerful medical linear accelerators have contributed to at least two deaths in the New York area. Although the mistakes were largely due to human error, buggy software also played a role. "...the records described 621 mistakes from 2001 to 2008... most were minor... The Times found that on 133 occasions, devices used to shape or modulate radiation beams... were left out, wrongly positioned, or otherwise misused. On 284 occasions, radiation missed all or part of its intended target or treated the wrong body part entirely. ... Another patient with stomach cancer was treated for prostate cancer. Fifty patients received radiation intended for someone else, including one brain cancer patient who received radiation intended for breast cancer."

highly trained morons

[timmarhy]

year ago i worked in a pathology lab, and i can atest to the fact the medical field is populated with a lot of highly trained morons. many times the application of these treatments aren't done by someone with enough brain power to understand whats actually happened.

Not a new problem

Bad software combined with poor training is not a new problem. In fact, one of the most famous serious failures of medical radiation technology. The most famous example is the Therac-25 debacle in the 1980s http://en.wikipedia.org/wiki/Therac-25 which caused multiple deaths. In that case, a combination of bad software design (leading to race conditions), bad hardware interfaces and training issues combined to create a perfect storm of bad conditions. This appears in textbooks. Problems like this shouldn't still be happening.
