During hospital admission, presence of delirium was assessed daily according to the Confusion Assessment Method criteria.

Longitudinal analysis of the trajectory of serum CRP levels using the Generalized Estimating Equations (GEE) method identified that higher CRP levels were associated with postoperative delirium.

No significant differences in serum CRP levels were found when we compared patients with short (1\u20102 days) and more prolonged delirium (3 days or more).<\/jats:p>\n                  <\/jats:sec>\n
