Severe sepsis and septic shock are frequently complicated by an encephalopathy ranging from confusion to coma (sepsis-associated encephalopathy, SAE).
To characterize risk factors and the prognostic contribution of SAE in adult patients.
We conducted a retrospective analysis of all patients with severe sepsis or septic shock included in the French prospective multicenter (n = 12 ICUs) OUTCOMEREA database between 1997 and 2014. We excluded patients with acute brain injury as a cause of ICU admission. SAE was defined by a Glasgow coma scale < 15 at ICU admission. Independent factors associated with SAE were identified using multivariate logistic regression analysis. Data are presented in median (IQR) or number (%).
Among the 18713 patients of the cohort, 3486 patients with severe sepsis or septic shock at admission were identified. Among them, 137 patients with primary acute brain injury were excluded. Data from 3349 patients (age 66 (54-77) years, male sex 61%, medical admission 71%) were analyzed. Overall, 1586 (47%) patients had evidence of SAE on ICU admission. SAE was more frequently observed in patients with bloodstream infections (88% vs. 79%, p < 0.01) and in patients with pneumonia (45% vs 33% p < 0,01). Compared to patients without SAE, patients with SAE had higher SOFA scores (10 (7-12) versus 7 (4-9) p < 0.01), a higher length of stay in the ICU (8 (3-17) days vs. 6 (3-14) days p < 0.01), a higher ICU mortality (40% vs. 18%, p < 0.01) and a higher hospital mortality (52% vs. 29%, p < 0.01).
In multivariable logistic regression analysis, after adjustment for type of admission, immune status, history of psychiatric disorder, chronic alcohol consumption, and SAPS II score, the following parameters, identified on the day of ICU admission, remained independently associated with SAE
