Thrombelastometry-guided Blood Component Administration Versus Standard of Care in Patients With Decompensated Liver Cirrhosis Undergoing Invasive Procedures

This measure represents the percentage of patients within the study population who received at least one transfusion of any blood component during study period. It is calculated by dividing the number of patients who were administered one or more units of a blood product by the total number of eligible patients in the cohort, and multiplying by 100 to express the result as a percentage. Blood products include platelets, fresh frozen plasma, or cryoprecipitate.

The incidence of major bleeding within the first 24 h after high risk of bleeding invasive procedures. It quantifies early clinically significant hemorrhagic complications and is typically expressed as a percentage or rate.

For the purposes of this measure, major bleeding is defined according to standardized clinical criteria. Commonly applied definitions include adapted criteria from the International Society on Thrombosis and Haemostasis (ISTH) or similar consensus frameworks. A bleeding event is classified as major if it meets one or more of the following conditions: fatal bleeding, symptomatic bleeding in a critical area or organ (intracranial, intraspinal, intraocular, retroperitoneal, pericardial, or intramuscular with compartment syndrome), a decrease in hemoglobin of ≥2 g/dL (≥20 g/L) within 24 hours attributable to bleeding

, transfusion of ≥2 units of packed red blood cells due to acute blood loss, bleeding requiring urgent procedural or surgical intervention.

This measure represents the proportion of transfusion episodes that are complicated by an acute transfusion-related adverse event occurring during or within 24 hours after the administration of a blood component. It will be expressed as a percentage and it will be calculated by dividing the number of transfusion episodes complicated by at least one qualifying acute adverse event by the total number of transfusion episodes administered during the study period. An acute transfusion-related adverse event is defined as a new clinical sign or symptom occurring during transfusion or within 24 hours after completion, for which a causal relationship to the transfused blood component is suspected, probable, or definite. The investigators will evaluate transfusion-associated cardiac overload, acute hemolytic transfusion reactions, anaphylactic reactions, febrile non-hemolytic reactions and urticarial reactions.

The investigators will evaluate the hospital length of stay in both study arms

This measure represents the proportion of patients who die from any cause during hospital admission. It captures all-cause mortality occurring between the time of hospital admission and discharge and is typically expressed as a percentage of the total eligible patient population.

This measure represents the proportion of patients who die from any cause within 30 days of a defined index event. The index event will be high risk of bleeding invasive procedure. The outcome will be expressed as a percentage and will reflect short-term mortality risk beyond the inpatient setting. 30-day mortality is defined as death from any cause occurring within 30 calendar days of the high risk of bleeding invasive procedure regardless of whether the patient is hospitalized, discharged, or transferred at the time of death. Mortality status will be evaluated through telephone follow-up with patients or family members
