Seriously did they spend a lot on this research, because I bet 75% of nurses with some experience at the bedside can tell you if a patient has C. diff. Even from the hallway at that particular time, nurses can make an educated guess as to whether someone has C. diff.
If fact nurses are so good we can tell the difference between the smells of a GI bleed bowel movement, C. diff diarrhea and hospital cafeteria food flatus. Don’t try to impress your friends or family with this fact during Christmas vacation.
Another good way to know if a patient has C. diff. When you are floated to a new floor, look at your assignment. Yes, your patient in isolation will be the one with C. diff.
You want me to spend my life doing what? Pick him, no pick him.
