摘要：
Background: Early assessment of the individual trauma load in major trauma patients is difficult. A simple and reliable prognostic factor already available in the emergency room would help the emergency physician to make appropriate therapeutic decisions, e.g., when and how to operate on major fractures. The aim of the study was to evaluate the prognostic value of prothrombin time (PT). Patients and Methods: The German Trauma Registry is a prospective, standardized and anonymous documentation of severely injured patients. 3,814 patients were included in the registry. 1,351 patients with an Injury Severity Score (ISS) ≤ 16 and complete data for specific variables (PT, Trauma Score + Injury Severity Score [TRISS], survival until discharge) were included in the study. The PT was measured on the patient's arrival in the emergency room. Three different analyses were performed. 1. According to clinical judgment, three groups of patients were compared (PT ≥ 60%, PT 40-59%, PT < 40%). A univariate analysis compared therapeutic interventions and outcome variables between the three groups. 2. A receiver-operator-characteristic (ROC) curve analysis compared the performance of PT with the prognostic standard TRISS. 3. A multivariate logistic regression was performed in order to evaluate PT as an independent prognostic variable. Results: PT values showed a good inverse correlation with the severity of injury and the level of therapeutic interventions. The ROC analysis as well as the regression revealed PT as a significant prognostic factor although it showed a slightly worse performance compared to TRISS. Conclusions: As PT, in contrast to TRISS, is readily available already in the emergency room, it can be used as a screening variable for the assessment of a patient's trauma load and thereby help in the decision-making for further operative treatment of major trauma patients.
