Hemostasis in Liver Disease Within Patient Blood Management: A Scoping Review of the Current Literature

Background/Objectives: The objective of this study was to map and synthesize the current evidence on hemostasis in chronic and acute liver disease within the framework of Patient Blood Management (PBM). Methods: Because research in this field is heterogeneous—spanning mechanistic studies, observational data, randomized controlled trials, guidelines, and expert reviews—a scoping review was selected to comprehensively map concepts. Findings were synthesized narratively to reflect the breadth and heterogeneity of available research. Results: Hemostasis in liver disease is characterized by a fragile state of rebalanced coagulation, where parallel reductions in pro- and anticoagulant factors coexist with variable fibrinolytic disturbances and thrombocytopenia. Conventional coagulation tests (CCTs) do not accurately reflect bleeding risk, whereas viscoelastic assays and thrombomodulin-modified thrombin generation testing provide a more physiologic assessment, though with limitations. Most bleeding events arise from portal hypertension rather than coagulopathy, and the routine prophylactic correction of abnormal results of CCTs is not supported by evidence. PBM-aligned strategies—such as restrictive transfusion, targeted fibrinogen replacement, and use of thrombopoietin receptor agonists (TPO-RAs)—reduce unnecessary blood product use. Thrombosis burden is increasingly recognized in this patient population. Anticoagulation is generally safe when individualized to liver function and clinical context, however significant variability persists in clinical practice, and high-quality data remain limited for advanced disease. Conclusions: Hemostasis in liver disease reflects a dynamic and unstable equilibrium rather than a simple bleeding tendency. Diagnostic and therapeutic strategies grounded in PBM principles improve safety by avoiding unnecessary transfusion and emphasize individualized care. Despite advances in understanding rebalanced hemostasis, major gaps remain in predicting thrombotic risk, standardizing advanced coagulation testing, and defining optimal management across disease stages.
