Procalcitonin and C-reactive protein levels at admission as predictors of duration of acute brain dysfunction in critically ill patients.

Associations of biomarkers with delirium/coma-free days After adjusting for covariates, higher baseline procalcitonin levels were associated with fewer DCFDs, that is, more brain dysfunction (OR, 0.5; 95% CI, 0.3 to 1.0; P = 0.04; Table 2 and Figure 1 ), and higher baseline CRP levels showed a trend towards fewer DCFDs (OR, 0.6; 95% CI, 0.3 to 1.1; P = 0.08; Table 2 and Figure 2 ).
