Incidence and prevalence of common respiratory pathogens before and after implementation of the Cystic Fibrosis Foundation Infection Prevention and Control Guideline.

Background: The 2013 Cystic Fibrosis Foundation's Infection Prevention and Control Guideline (CFF IP&C) was developed to reduce the risk of acquisition and transmission of respiratory pathogens in patients with cystic fibrosis (CF).

Objective: We hypothesised that the incidence of common CF respiratory pathogens would decrease at our centre after implementation of the guideline.

Methods: All patients with CF seen at our centre from August 2012 through August 2017 who had respiratory cultures were included.
