Demographics and medical data
A total of 309 CF patients were involved in the study. Of these 309
patients, 120 had their first isolation of P. aeruginosa and 61
had first isolation of MRSA during the study period (2015-2019). 18
patients from P. aeruginosa group and 13 patients from MRSA group
were excluded from the study due to lack of medical records or delayed
treatment due to the presentation to the clinic later than the first
month of isolation. Patients’ baseline characteristics are presented in
Table 1. Baseline characteristics were similar between IV and non-IV
treatment arms except patients who had IV treatment in P.
aeruginosa group were younger (aged 5.1 ± 4.9 vs 8.1 ± 5.8 p =0.02).
