Neurocognitive function was observed in 22/30 patients (73%) at postoperative day four when defined by a decrease from baseline RBANS score. Patients with acute kidney injury (Cr ≥ 1.2) on POD4 trended towards impaired neurocognitive function (4/30 patients, 13%, p=0.06). Postoperative leukocytosis (WBC ≥ 10.5x103mm) on POD4 was associated with NCD when compared to their baseline function (p=0.03) [Figure 1B]. Further demographic information including age, race, education and comorbidities can be found in a previous publication, along with time on bypass and hospital length of stay.5
