Priority 7 from the Healthcare Associated Infections Project

UNCERTAINTY: What is the role of change of bacteria in patients or the environment in the development of infection in hospital? (Priority 7)
Overall ranking 7
JLA question ID 0088/7
Explanatory note There are millions of bacteria in the human body: some are good and some are bad. These are maintained in balance in a healthy individual. The change of type of bacteria because of the various treatments that they receive, may be one of the reasons for increased susceptibility of patients in the critical care unit for HCAI. Understanding this role may result in alternate treatments.

Systematic review: Yes, but in the post-operative setting
Lederer et al. BMC Surg. 2017 Dec 4;17(1):125
Kasatpibal et al. Clin Infect Dis. 2017 May 15;64(suppl_2):S153-S160
Systematic review details:
Lederer: Better quality studies are necessary
Kasatpibal: high risk of bias systematic review, so conclusions are misleading
