Evaluation of red blood cell distribution width and platelet distribution width in combination with Glasgow Coma Score for the prognosis of patients with severe traumatic brain injury / 医学研究生学报

ABSTRACT

ObjectiveAt present, there are few studies on prognostic indicators for patients with severe traumatic brain injury (STBI). This paper aims to explore its significance by analyzing the demographic characteristics of patients with STBI, as well as parameters such as clinical laboratory test indicators.MethodsA retrospective analysis was performed on 139 STBI patients admitted to the Department of Emergency Medicine, General Hospital of Eastern Theater Command from January 2017 to December 2018. According to the 28-day death event, the participants were divided into the survival group (n=108) and the death group (n=31). Indicators such as Glasgow Coma Score (GCS), red blood cell distribution width (RDW), platelet distribution width (PDW) and clot-related indicators were collected. Univariate and multivariate logistic regression were used to analyze the risk factors related to death, and receiver operating characteristic (ROC) curve was adopted to determine their prognostic values.ResultsThere were significant differences in GCS, RDW and PDW between the two groups. RDW (OR=4.577, 95% CI 1.704-12.291), PDW (OR=1.346, 95% CI 1.093-1.657) and GCS (OR=0.469, 95% CI 0.301-0.730) were risk factors for death of STBI patients. The area under the curve (AUC) of RDW, PDW and GCS scores were 0.735 (0.640-0.840), 0.675 (0.553-0.796) and 0.737 (0.638-0.837), respectively, and the AUC of the combination of the three was 0.840 (0.748-0.932), which was significantly better than that of single diagnosis.ConclusionRDW, PDW combined with GCS can effectively evaluate the prognosis of patients with STBI, which has important guiding value for clinicians′ diagnosis and treatment.
