Abstract:

Objective

To evaluate the value of RETRA score in predicting the prognosis of trauma patients in ICU.

Methods

The clinical data of 903 trauma patients in ICU of Chenzhou Hospital Affiliated to University of South China from January 2020 to August 2022 were retrospectively analyzed, and they were divided into a death group (n = 62) and a survival group (n = 841) according to the 30 d prognosis after injury. The basic clinical data, laboratory tests, abbreviated injury scale (AIS), injury severe score (ISS), and RETRA score were compared between the two groups. Receiver operating characteristic (ROC) curves were used to analyze the efficacy of different trauma scores in assessing the 30 d prognosis of trauma patients, and the Z-test was used to compare the area under the curve (AUC).

Results

The age, systolic blood pressure, diastolic blood pressure, mean arterial pressure, prothrombin time (PT), activated partial thromboplastin time (APTT), length of hospital stay, mechanical ventilation time, RETRA score, ISS score, main injury site of head and abdomen, age 55-65, 66-75 and > 75 years, prehospital endotracheal intubation, unilateral and bilateral pupil dilation, Glasgow coma score ≤ 8, AIS head score ≥ 3, and rates of circulatory failure, coagulation disorders, mechanical ventilation and respiratory failure showed statistically significant differences between the two groups (all P < 0.05). The ROC analysis showed that the RETRA score was the best predictor for 30 d prognosis of trauma patients, with an AUC of 0.849 [95% confidence interval (CI) (0.798, 0.900), P < 0.001], sensitivity of 75.8%, specificity of 78.1%, and a cut-off value of 3.5, followed by the ISS score with an AUC of 0.627 [95%CI (0.552, 0.703), P < 0.001], sensitivity of 58.1%, specificity of 70.7%, and a cut-off value of 23.0. The AIS score had no predictive effect (P = 0.677). The Z-test showed that the RETRA score was better than the ISS score and AIS score (Z = 7.677, 5.237; both P < 0.001).

Conclusion

The RETRA score has a high predictive value for 30 d prognosis of trauma patients in ICU.
