The 12-hour shift paradigm has cropped up relatively recently in our profession, and it is the norm for hospital nursing. Unless you wear a tie, you will work 12′s in almost any hospital setting except, occasionally, rehab. This scheduling framework is increasingly being targeted and questioned both regarding patient and nurse safety. For brevity, I won’t include a bunch of links, but perform a Web search for “12-hour shifts safety” or similar for your own curiosity. The summary is that nurses make more and worse errors with longer shifts and don’t sleep enough between shifts.
