A Black Box in Every Operating Room?

Medical malpractice attorneys know that it is often very difficult to determine what went wrong in a surgical procedure. Unless someone witnessed exactly what happened and is willing to testify about it, or unless the outcome was so bad it is presumed to be the result of negligence (a res ipsa loquitur claim, such as leaving a surgical instrument in the patient), the reasons for a bad outcome are often never known to the patient or his/her attorney.
