Risk Factors and Scoring System for Predicting Bacterial Resistance to Cefepime as Used Empirically in Haematology Wards

Table 4

Predictive score of cefepime resistance with 3 risk factors at onset of the first episode of bacteraemia^a.

Score	Number (%) of patients	% cefepime resistance	OR
0 risk factor	55 (53)	27	1
1 risk factor	30 (29)	63	4.6 (1.8 to 11.9)
2 risk factors	14 (14)	86	21.3 (4.4 to 104.1)
3 (all) risk factors	4 (4)	100

The 3 criteria are acute lymphoblastic leukaemia, beta-lactams administration during the month or at onset of bacteraemia, and time elapsed since hospital admission >18 days.
