Objective To compare the Scott Triggers (ST) Tool with the Munro scale for assessing the risk of pressure injuries in surgical patients, and to provide reference for selectinga suitable assessment tool. Methods The risk of pressure injuries in 413 surgical patients were assessed using the ST Tool and the Munro scale, and taking those developed pressure injury after surgery as golden criteria, then ROC and Bayes discriminant analysis were utilized to evaluate the assessment ability of the two scales. Results A total of 43(10.4%) surgical patients suffered from pressure injury. The area under the ROC of ST Tool and Munro scale was0.626 （95%CI:0.578-0.673） and 0.670 （95%CI:0.622-0.715）, and there was no significant difference (P＜0.05).The cross-validation method was used to test the accuracy of the two tools, the correct judgement rate of the Munro scale and the ST Tool was similar, which was 89.80% and 89.60% respectively. Conclusion Both the ST Tool and the Munro scale could be used assessing pressure injury in surgical patients, and the eva-luation effect is si-milar. The ST Tool is concise, thus its use in clinic is convenient and fast.
