Hospital eradication protocol
All patients with the first isolation of P. aeruginosa and MRSA were offered IV antibiotic eradication treatment. 14 days IV ceftazidime and amikacin were used for P. aeruginosa eradication. For the eradication of MRSA, 14 days IV teicoplanin was used in addition to 5 days 2% nasal mupirocin ointment and 5 days 4% chlorhexidine body wash. The regimens were adapted if a patient had any allergies or was resistant to any of the first-line antibiotics. If a patient did not accept hospitalization, an oral and/or inhalation eradication regimen was chosen by specialist decision.
