Background: Respiratory tract infections significantly contribute to morbidity and mortality of cystic fibrosis patients.
Methods: We conducted a systematic literature review (Pubmed 01/1966 up to 09/2003) in order to present recommendations for the isolation of CF patients colonized with Burkholderia cepacia spp., Pseudomonas aeruginosa, Stenotrophomonas maltophilia and Alcaligenes spp. Evidence and quality of 64 publications dealing with pathogen transmission or isolation measurements of colonized patients were evaluated.
Results: B. cepacia spp. was dealt most often with and 35 of 36 authors recommended the isolation of patients colonized with this pathogen. Isolation of patients colonized with P. aeruginosa was proposed by 21 of 25 authors. Only 5 studies concerned S. maltophilia or Alcaligenes spp.
Conclusions: A) B. cepacia spp. colonized patients need to get a single room for their own. B) P. aeruginosa colonized CF patients should be separated from non-colonized CF patients. C) Patients harbouring even multi drug resistant P. aeruginosa, S. maltophilia or Alcaligenes spp. may not share their room with immunocompromised patients and should also be isolated when treated in intensive care units.
