- •Exposure to invasive devices is a major risk factor for hospital-acquired infection.
- •Intensive care unit patients free of hospital-acquired infection who were exposed to multiple devices were identified.
- •5.0% of patients were multiexposed; 15.7% of patients remained uninfected.
- •Multiexposed infected patients differed from noninfected patients regarding mortality.
- •Patients did not differ regarding main risk factors for hospital-acquired infection.
