Delirium can be deadly if not diagnosed and treated. If that should occur, we all know that an Immediate Jeopardy citation is just around the corner. Don't let that happen to you and your residents.
All organizations should be aware of their rehospitalization rate and should be addressing this in their QAPI meetings - why did they go out, what could have been done to prevent it, was there a systems problem, were subtle indicators noted and charted, does a nurse need education, etc?
Behaviors are kind of like figuring out a mystery sometimes. And what helped stop a behavior today does not mean it will necessarily work tomorrow. And what may have caused the behavior today may be far more indicative of a serious medical issue - as is the case with delirium — tomorrow.
