Objective
To develop a clinical predictive score for hypofibrinogenemia in severely injured trauma patients.
Design
Retrospective cohort study.
Setting
Intensive Care Unit (ICU) at Hospital Joan XXIII.
Patients
Consecutive patients admitted to the ICU for severe trauma with significant bleeding between 2015 and 2021 were included. Patients with an Injury Severity Score (ISS) < 16 were excluded.
Interventions
Data were analyzed from the ICUTRAUMA registry, designed to establish the epidemiological profile of critically ill trauma patients in the province of Tarragona. The association between admission fibrinogen levels and ICU mortality was assessed using Cox regression with restricted cubic splines. A logistic regression model was then constructed to predict hypofibrinogenemia (≤203 mg/dl), from which a clinical score was developed and internally validated, and subsequently named FiT-6.
Main variables of interest
Association between initial fibrinogen levels and ICU mortality.
Results
A non-linear relationship was observed between fibrinogen levels and ICU mortality. Fibrinogen levels ≤ 203 mg/dl were significantly associated with increased mortality (HR: 1.66; 95%CI: 1.01–2.72). Six independent predictors of hypofibrinogenemia were identified: ionic calcium < 1 mmol/l, hemoglobin < 10 g/dl, platelets < 100 × 109/l, base excess < –6, Shock Index > –0.9, and lactate > 2 mmol/l. The model demonstrated good diagnostic performance (AUC-ROC 0.90) after cross-validation.
Conclusions
The FiT-6 score shows high predictive ability for identifying hypofibrinogenemia, which is associated with increased ICU mortality.
