“…Firstly, segregating patient by other methods would necessitate an alteration in clinic and ward infrastructure, which would be costly and for some units impossible, and secondly cross-infection with transmissible strains has been shown to confer an increased healthcare cost burden. 41 Finally, the emerging medicolegal consequences of allowing cross-infection between CF patients within the hospital environment, which can be costly, are also avoided.…”

ObjectivesTo assess if cohort segregation policies are effective in preventing cross-infection in cystic fibrosis (CF) clinics.DesignA prospective cohort study.SettingA large adult CF centre in Northwest England.ParticipantsAll CF patients cared for at the Liverpool adult CF centre 2003–2009.MethodsRegular sputum sampling with genotyping of pseudomonas aeruginosa (Psa) isolates led to a policy of inpatient and outpatient segregation by microbiological group.Main outcome measuresPrevalence and cross-infection/super-infection rates of a transmissible Psa strain, i.e. the Liverpool epidemic strain (LES) in adult CF patients at the Liverpool adult CF centre from 2003 to 2009.ResultsThere was a decline in the proportion of patients with LES (71–53%) and an increase in those with unique strains (23–31%) and without Psa infection (6–17%) from 2003 to 2009. There were two cases of LES super-infection and one case of new chronic Psa infection (with a unique strain). There were no cases of transmissible strain infection in patients previously uninfected by Psa.ConclusionsOur segregation policy has halted the spread of the commonest highly transmissible strain in the UK (LES) in our clinic, without endangering patients who were not previously infected with Psa. It confirms that if genotypic surveillance is used, it is unnecessary to segregate patients infected with unique strains from those without Psa infection.
