I had a flashback while starting this post, to the first day of my third year of medical school – the first day (in those days) that medical students spend time in the hospital helping to care for patients. My first rotation was trauma surgery – yes, trauma surgery – and at evening sign out, the medical resident in charge of our education and safety taught us the acronym “NMP.” It stood for “not my problem,” uttered after a beeper page was responded to about a patient that was not under our care. That moment conveyed important messages to me – that this was going to brutal, and she was going to shield us, which she did. I would only later ask the question, “from what?”
