Document Summary
Basically, the word that they want to use is healthcare-associated infections , because it is more broad. It includes a lot of things (nurses, dentists, etc; not just doctors). In 2002-2003, we started to become worried about these infections. Looking at statistics from these years, it is a real concern. It was estimated in canada during those years that this was one of the major causes of death. If the infection was within 48 hours of admission, then it most likely came from an outside source (based on incubation periods). As a general rule, though, this 48 hours does not make sense for every bacteria. Some have a longer and some have a shorter incubation period. It says that classically if the infection appears 48 hours after hospitalization, then it is considered nosocomial. However, they add that this should not be applied without thinking; ie: it really depends on the infection.
