The value of ultrasound technology combined with the Braden scale in predicting the risk of pressure injuries in patients with severe multiple injuries
Objective To investigate the value of the ultrasound technique score and the Braden scale in jointly predicting the risk of pressure injuries in patients with severe multiple injuries.Methods According to the inclusion and exclusion criteria,216 patients who were hospitalized in the Affiliated Central Hospital of Chongqing University from December 2022 to December 2023 were enrolled.The Braden scale and body sur-face ultrasound test results of each patient were collected,and the subject operating characteristic(ROC)curves of the Braden scale,the ultrasound score,and the Braden scale combined with the ultrasound score were counted respectively,and the area under the curve(AUC),sensitivity,specificity,and other predictive indexes were calculated,so as to analyze and compare the clinical value of the prediction of the combined means.Re-sults The incidence of pressure injuries in patients with severe multiple injuries was 24.5％.The AUC of the Braden scale for the risk of pressure injuries in patients with severe multiple injuries was 0.602[95％confi-dence interval(95％CI)0.507-0.696,P=0.026].The sensitivity for diagnosing pressure injuries was 0.868 and the specificity was 0.184 when using a Braden score of 12 as the cut-off point.The AUC for the ul-trasound technique score was 0.898(95％CI 0.852-0.944,P＜0.001).The sensitivity for diagnosing pres-sure injuries was 0.962 and the specificity was 0.767 when using an ultrasound score of ≥1 as the cut-off point.The AUC for the combination of the Braden score and the ultrasound technique for the risk of develo-ping pressure injuries in patients with severe multiple injuries was 0.927(95％CI 0.887-0.958,P＜0.000 1).The sensitivity was 0.975 and the specificity was 0.819 when Braden score ≤12 and ultrasound score ≥1 were used as cut-off points.Conclusion In patients with severe multiple injuries,the specificity of the Braden scale for pressure injuries prediction is poor,and the Braden score combined with the ultrasound technology is a more optimized means of assessing pressure injuries risk.
