Patients withappear to be at heightened risk of death, according to results of a large retrospective cohort study.
The risk of death in the study increased with the severity of the sepsis-associated coagulopathy, which was defined using international normalized ratio (INR) and platelet counts.
Those findings suggest that the severity of coagulation abnormalities might be used to quantify mortality risk, according to investigator, of the division of pulmonary and critical care medicine, Washington University, St. Louis, and his coinvestigators.
“Future trials of sepsis therapies targeting the coagulation cascade should take into account the presence or absence of sepsis-associated coagulopathy, as well as the severity of sepsis-associated coagulopathy, when formulating potential trial designs,” the investigators wrote in the journal.
Their retrospective cohort study included 6,148 consecutive patients with sepsis or septic shock hospitalized at a 1,300-bed urban academic medical center between 2010 and 2015. Of that group, 26% had sepsis-associated coagulopathy, defined as having both an INR of 1.2 or higher and a platelet count less than 150,000/mcL. Sepsis-associated coagulopathy was classified as mild for 4%, moderate for 16%, and severe for 6% of the cohort.
Hospital mortality was 25.4% for patients with no sepsis-associated coagulopathy, the research team found, increasing progressively from 27.0% for mild, 40.7% for moderate, and 56.1% for patients in the most severe category of sepsis-associated coagulopathy (P less than .001).
Hospital and ICU days also increased progressively according to the severity of coagulopathy, they reported.
