Respiratory infections are the most important cause of morbidity and mortality in patients with cystic fibrosis (CF). These infections are typically caused by a limited number of respiratory pathogens, particularly Burkholderia cepacia complex (BCC) and Pseudomonas aeruginosa (PA). Since the 1980s, several outbreaks of unique strains of PA and BCC among CF patients attending the same CF care centres have been described, leading to a sharp decline in the patients’ health. One of the measures adopted in CF centres to interrupt ongoing outbreaks is the separation of patients with a respiratory tract culture that is positive for PA or BCC from patients who are not infected. This type of measure has been implemented routinely in many CF centres to prevent cross-transmission of PA and BCC. The aim of this review was to determine what evidence is available to support the efficacy of isolation (or segregation) practices in preventing, delaying or reducing the risk for CF patients of acquiring PA and BCC. A systematic review of scientific literature from 1980 to 31 December 2004 was performed. Existing guidelines regarding infection control in CF were also analysed.

Abstract

Respiratory infections are the most important cause of morbidity and mortality in patients with cystic fibrosis (CF). These infections are typically caused by a limited number of respiratory pathogens, particularly Burkholderia cepacia complex (BCC) and Pseudomonas aeruginosa (PA). Since the 1980s, several outbreaks of unique strains of PA and BCC among CF patients attending the same CF care centres have been described, leading to a sharp decline in the patients’ health. One of the measures adopted in CF centres to interrupt ongoing outbreaks is the separation of patients with a respiratory tract culture that is positive for PA or BCC from patients who are not infected. This type of measure has been implemented routinely in many CF centres to prevent cross-transmission of PA and BCC. The aim of this review was to determine what evidence is available to support the efficacy of isolation (or segregation) practices in preventing, delaying or reducing the risk for CF patients of acquiring PA and BCC. A systematic review of scientific literature from 1980 to 31 December 2004 was performed. Existing guidelines regarding infection control in CF were also analysed. In total, 398 relevant papers were retrieved. Only 10 welldesigned studies were found that evaluated the efficacy of isolation practices in preventing the transmission of respiratory pathogens in CF care centres (one prospective controlled study, one retrospective cohort study, five ‘beforeeafter’ studies and three cross-sectional studies. No systematic reviews or randomized controlled trials exist on this subject. In the absence of studies with an experimental, controlled design, the efficacy of isolation practices in preventing the transmission of respiratory pathogens in CF remains unproven. However, notwithstanding the considerable limits represented by the study designs, which were mainly retrospective, the observational studies reviewed seem to support the implementation of isolation (or segregation) measures to reduce the risk of transmission of BCC and PA in CF patients.
