We've recently had several morning reports and noon conferences on this topic. Given the recent statistic in nejm that 75% of physicians will face a malpractice suit by age 65 (although a much smaller percentage of those are paid), it seems that it may not matter much what we do - disclose, discuss, hide, ruminate alone.
But I disagree with this perception. I do not think we are powerless in these situations, and I think many physicians agree that disclosure and open discussion are not only the right things to do ethically, but help us to heal as well.
Sahmd is right that these are difficult topics and discussions best led by experts. However, time and again studies have shown that honest and forthcoming discussion can actually lead to a decrease in lawsuits, and an increase in patient safety as well as physician well being. (in fact, in my state, an apology to patients/families cannot be used against you in court).
Not sure where you are in your career, but if you're in residency it may help to talk to your chief, advisor, etc to see if training is available. You are not the only one facing this dilemma, and learning how to cope with medical error is an important part of our medical training - one which has been grossly ignored and shamed for too long.
Every state has different laws, and we had a medical lawyer as well as an ethicist among others leading our training sessions. We had small groups that discussed our personal experiences with medical error, and it was really helpful to acknowledge and normalize our feelings and fears.
