Relationship between coagulopathy score and survival in critically ill patients with liver cirrhosis and sepsis: a retrospective study.

backgroundThis research focused on exploring the association between coagulopathy scores and the survival outcomes, both short-term and long-term, in individuals diagnosed with liver cirrhosis complicated by sepsis.

methodsThis study retrospectively analyzed data from individuals with liver cirrhosis and sepsis who were admitted to the intensive care unit (ICU) at Beth Israel Deaconess Medical Center between 2008 and 2022. The main outcome of interest was all-cause mortality within 28 days post-admission, while the secondary outcome assessed mortality within 90 days. We used the Kaplan-Meier analysis to compare the mortality risk among the different groups. To evaluate the relationship between coagulopathy score and mortality risk in patients with liver cirrhosis and sepsis, a multivariate Cox proportional hazards regression analysis was performed. The predictive performance of the coagulopathy score for short- and long-term all-cause mortality was assessed using receiver operating characteristic (ROC) curve analysis, which included evaluation of its sensitivity, specificity, and area under the curve. Subgroup analyses were performed to evaluate the relationship between coagulopathy score and survival across different groups.

resultsThe study included a total of 2,278 patients. Kaplan-Meier survival analysis demonstrated that individuals with elevated coagulopathy scores exhibited markedly higher rates of ICU mortality, in-hospital mortality, as well as 28-day and 90-day mortality, with all log-rank tests yielding P-values of less than 0.001. The results of the multivariate Cox regression analysis showed that an elevated coagulopathy score was independently linked to higher 28-day and 90-day all-cause mortality, both before and after controlling for potential confounders. ROC curve analysis showed that although the coagulopathy score was slightly less predictive of prognosis than the Model for End-stage Liver Disease score, it significantly outperformed the Sequential Organ Failure Assessment score and the Sepsis-induced Coagulopathy score. Subgroup analysis revealed no significant interaction between the coagulopathy score and survival across the different subgroups.

conclusionsHigher coagulopathy scores in critically ill patients with liver cirrhosis and sepsis were independently associated with poor prognosis. Due to its simplicity and potential predictive value, the coagulopathy score can serve as an effective complement to existing clinical tools for managing critically ill patients with liver cirrhosis and sepsis.
