Background: The etiology of postoperative delirium (POD) following vascular surgery is generally unknown. The incidence, however, can be as high as 35%. A possible neuroinflammatory basis for delirium is likely and C-reactive protein (CRP) as a marker for inflammation can possibly play a predictive role.Methods: Between March 2010 and September 2012, 277 consecutive elective vascular surgery patients were prospectively evaluated for the diagnosis of POD. Various potential risk factors, including postoperative CRP values, were collected.Results: The mean age of the patients was 69 +/- 11 years (range 21-92). The mean hospital length of stay was 6 +/- 4 days (range 1-33). Sixteen patients (6%) developed POD during hospital stay. Univariate analysis revealed multiple comorbidities (P = 0.001), postoperative elevated CRP levels (P = 0.001), intensive care unit admittance (P = 0.01), and open aortic surgery or amputation procedures (P = 0.0001) to be significantly related to the diagnosis POD. Multivariate logistic regression analysis confirmed the relationship between an elevated CRP value and POD (odds ratio [OR] 1.01, 95% confidence interval 1.00-1.03, P = 0.04). The sensitivity analyses yielded essentially similar results. Based on OR, it can be calculated that the risk of POD is increased by approximately 35% if the CRP concentration is 50 mg/L, and by approximately 90% if the CRP concentration is 100 mg/L (compared with a CRP concentration of 5 mg/L). Thirty-one percent (5/16) of patients with POD needed a long-stay care facility after discharge (P = 0.0001).Conclusions: In this study, CRP can be used as a marker for an increased risk of POD after vascular surgery. In addition, it was found that POD was associated with a 10-fold increase in the need of long-stay care after discharge.
