I worked in a fairly small hospital in the past and they had standing orders for so many things. The Doctor would have to sign them, and a few orders on the page would have a box for check off but it was done ahead of time. Would that work in bigger places? It's been a few years since I have worked in a hospital but how that do?
You can have 3 different types of alarms on and a person can still fall. Anyone on any of the shifts from admission to fall could have changed things, added something. What about staffing or layout of building etc. So many factors. Document, document, document!
