We examined the institutional variations in anticoagulation therapy for sepsis-induced disseminated intravascular coagulation (DIC) and their effects on patient outcomes. This post hoc analysis of a cohort study included 3195 patients with severe sepsis across 42 intensive care units. To evaluate differences in the intensity of anticoagulation therapy, the proportion of patients receiving anticoagulation therapy and the total number of patients with sepsis-induced DIC were compared. Predicted in-hospital mortality for each patient was calculated using logistic regression analysis. To evaluate survival outcomes, the actual/mean predicted in-hospital mortality ratio in each institution was calculated. Thirty-eight institutions with 2897 patients were included. Twenty-five institutions treated 60% to 100% (high-intensity institutions), while the rest treated 0% to 50% (low-intensity institutions) of patients with sepsis-induced DIC having anticoagulant therapy. Every 10-unit increase in the intensity of anticoagulant therapy was associated with lower in-hospital mortality (odds ratio: 0.904). A higher number of high-intensity institutions (compared to low-intensity institutions) had lower in-hospital mortality and fewer bleeding events than predicted. In conclusion, institutional variations existed in the use of anticoagulation therapy in patients with sepsis-induced DIC. High-intensity anticoagulation therapy was associated with better outcomes.
