Amongst MRSA isolates, there was a highly significant decrease in the proportion of resistance to gentamicin from 58.4% in 1999 to 13.1% in 2003 (p < 0.001).
Amongst MRSA isolates, there was a highly significant decrease in the proportion of resistance to gentamicin from 58.4% in 1999 to 13.1% in 2003 (p < 0.001).
Chi2 suggested that the increase was of borderline significance (P = 0.06).
Patients in Group A, had as expected, higher values of ESR, 58 mm/h (±SD 33.4) vs 90 mm/h (±SD 28.9) (p < 0.0001) and CRP compared with patients in Group B, although the last did not reach statistical significance (p = 0.07).
Moreover, the length of stay in the hospital showed a trend toward reduction (from 9 ± 2 days before protocol implementation, to 7 ± 5 days).
There was a male predominance and a clear trend age disbalance as 71% of the patients were at least 60 years old. 26.2% of the subjects were already taking antibiotics when admitted. 47.2% of the subjects were admitted to hospital with very low Fine scores (I–III), but hypoxemia occurred in 34.1% of them.
