Abstract |
Background |
The present study aims at identifying the risk factors for ventilator-associated pneumonia (VAP) Staphylococcus aureus (S. aureus) in patients with severe brain injury (SBI).
Methods |
In this multicentre, retrospective, observational study, patients ≥ 18 year old who had SBI (Glasgow coma scale GCS score < 9) who received mechanical ventilation for at least 48 h were analysed. The main objective was to identify risk factors for S. aureus VAP vs VAP due to other pathogens and to identify risk factors for S. aureus VAP vs patients who did not experience VAP.
Results |
Eight hundred and forty-seven patients with SBI were admitted in ICU after severe traumatic brain injury (n = 489, 58%), aneurysmal SAH (n = 156, 18%), stroke (n = 27, 3%), spontaneous intracranial haemorrhage (n = 80, 9%), arteriovenous malformation rupture (n = 25, 3%), and other causes (n = 70, 8%). Three hundred fifty of 847 patients (41%) had VAP with S. aureus (n = 161) or other pathogens (n = 189). In patients with VAP, the multivariate analysis shows that age per 10 years of ageing (OR 0.80, 95% CI [0.70; 0.90]; p < 0.001) and tobacco use (OR 0.54, 95%CI [0.33;0.88]; p = 0.014) were protective factors against S. aureus. Age per 10 years of ageing remained a protective factor against S. aureus VAP vs no VAP (OR 0.80, 95%CI [0.73; 0.89], p < 0.001).
Conclusions |
In this retrospective study involving patients with SBI and who experienced VAP, increased age and tobacco use were protective factors against VAP due to S. aureus. Increased age remained protective against S. aureus in VAP vs no VAP analysis.
