Dealing With Others' Mistakes

My husband just finished his first year of practicing medicine. The other day, he received a letter from the hospital stating another doctor was reviewing some of his cases from the past year. I'm not sure of the reasons for the procedure, except for the fact that it was his first year out of residency, and he's still in a kind of "probationary" period before he becomes a partner in his practice. Anyway, the letter stated most of his surgery cases looked fine, but it mentioned the fact that during one of them, a patient died of cardiac complications while he was operating, something unavoidable that he had handled just fine. He took the letter to his office manager because he never remembered a patient of his dying during surgery over the past year. They checked with medical records and found out that, not only did the patient die during a heart bypass surgery (my husband's an OB/Gyn), but also, the patient was a MAN (again, my husband is an OB/Gyn). Apparently, the person reviewing my husband's cases hadn't reviewed them very thoroughly because she would have seen that my husband had had no contact whatsoever with this patient. She must have only been reviewing cases by medical record numbers, which makes me believe that either the wrong doctor got connected with the wrong patient somewhere in the database, or the doctor reviewing my husband's cases looked up the wrong medical record number to begin with. Whatever the case, it made my husband laugh, but it made me frustrated for him. Such reviews probably go on his permanent record, and having wrong information there can give the wrong impression to others (employers and patients) later on. I know that his office manager and others are working on getting the mistake corrected, but still, it should never have happened. I think I'm most upset at the reviewer. If she didn't review this particular case as well as she should have, what else did she miss? Apparently, she also stated my husband did a laparoscopy case where the patient died. He doesn't remember that happening either, so his office is checking up on that case, too. There's another OB/Gyn in the area with a similar last name as my husband's, so, again, the case could have been connected with the wrong doctor. Have any of you and your spouses dealt with a situation like this? What did you do? I know that we humans aren't perfect, but still. This shouldn't have happened!
