A hospital is, by its nature, the scene of constant life-or-death situations. It's the work we nurses, doctors and other health professionals do; we chose it. The threat of harm can jazz you up or bring you down, but what it should demand, always, is the highest possible level of professionalism. Who's at risk when that doesn't occur? This isn't about hurt feelings or bruised egos. Modern health care is complex, highly technical and dangerous, and the lack of flexible, dynamic protocols to facilitate communication along the medical hierarchy can be deadly.
