Bottom Line: Fever is associated with a poor outcome in severely brain-injured patients, and its control is one of the therapies used in this condition.Moreover, the density of VAP incidence was compared between the two groups.Fever control in brain-injured patients was a major risk factor for VAP occurrence, particularly when applied for > 3 days.

ABSTRACT

Introduction: Fever is associated with a poor outcome in severely brain-injured patients, and its control is one of the therapies used in this condition. But, fever suppression may promote infection, and severely brain-injured patients are frequently exposed to infectious diseases, particularly ventilator-associated pneumonia (VAP). Therefore, we designed a study to explore the role of a fever control protocol in VAP development during neuro-intensive care.

Methods: An observational study was performed on severely brain-injured patients hospitalized in a university ICU. The primary goal was to assess whether fever control was a risk factor for VAP in a prospective cohort in which a fever control protocol was applied and in a historical control group. Moreover, the density of VAP incidence was compared between the two groups. The statistical analysis was based on a competing risk model multivariate analysis.

Results: The study included 189 brain-injured patients (intervention group, n = 98, and historical control group, n = 91). The use of a fever control protocol was an independent risk factor for VAP (hazard ratio 2.73, 95% confidence interval (1.38, 5.38; P = 0.005)). There was a significant increase in the incidence of VAP in patients treated with a fever control protocol (26.1 versus 12.5 VAP cases per 1000 days of mechanical ventilation). In cases in which a fever control protocol was applied for > 3 days, we observed a higher rate of VAP in comparison with the rate among patients treated for ≤ 3 days.

Conclusions: Fever control in brain-injured patients was a major risk factor for VAP occurrence, particularly when applied for > 3 days.

Mentions: All patients in the intervention group were treated with the fever control protocol when their fever was >38.2°C. The delay before its effective application was less than 24 hours, and its median duration was four days (range, two to six days).
