Text: Practices associated with reduced infection risk included prophylaxis with second-generation cephalosporins (HR : 0. 70 ; 95 % CI : 0. 52 to 0. 94), whereas post-operative antibiotic duration > 48 h (HR : 1. 92 ; 95 % CI : 1. 28 to 2. 88), stress hyperglycemia (HR : 1. 32 ; 95 % CI : 1. 01 to 1. 73) ; intubation time of 24 to 48 h (HR : 1. 49 ; 95 % CI : 1. 04 to 2. 14) ; and ventilation > 48 h (HR : 2. 45 ; 95 % CI : 1. 66 to 3. 63) were associated with increased risk.
