Abstract
Background Two different criteria for evaluating coagulopathy in sepsis were recently released:
sepsis-induced coagulopathy (SIC) and sepsis-associated coagulopathy (SAC). Although
both use universal haemostatic markers of platelet count and pro-thrombin time, significance
and usefulness of these criteria remain unclear.
Objective This article validates and evaluates the significance of SIC and SAC criteria compared
with the International Society on Thrombosis and Haemostasis (ISTH) overt disseminated
intravascular coagulation (DIC) and Japanese Association for Acute Medicine (JAAM)
DIC criteria.
Methods Clinical characteristics of patients from a nationwide Japanese cohort were classified
by SIC, SAC or DIC status and relations between criteria were examined. We evaluated
associations between in-hospital mortality and anticoagulant therapy according to
the SIC, SAC or DIC status to clarify the significance of criteria for introducing
anticoagulants. Intervention effects were analysed by Cox regression analysis adjusted
by propensity scoring.
Results Incidences of coagulopathy diagnosed by SIC and JAAM DIC were similar, whereas those
of SAC and ISTH overt DIC were about half of the former two (61.4%, 60.8% vs. 45.3%,
29.3%). Severity and mortality of all criteria were almost comparable. For validating
initiation of anticoagulation, favourable effects of anticoagulant therapy were observed
only in sub-sets with, and not without, coagulopathy diagnosed by all four criteria.
Slight non-significant differences between anticoagulant groupings were found in ISTH
overt DIC- and SAC-negative populations, suggesting that some patients even ‘without’
these criteria may benefit from anticoagulant therapy.
Conclusion Newly developed SIC diagnostic criteria for coagulopathy may be valuable in detecting
appropriate candidates for anticoagulant therapy in sepsis and a useful alternative
to conventional DIC scoring systems.
