Abstract:
Objective:To design risk factors evaluation form for pressure injury in adult orthopedic operations and to test its sensitivity and specificity.Methods:Based on the literature review and the items in the existing risk factor assessment form of stress injury, the risk factors of stress injury in adult orthopedics were extracted. After an expert meeting and Delphi expert consultation, an evaluation form of risk factors for stress injury in adult orthopedics was formed. A total of 1 701 adult orthopedic patients who underwent elective surgery in a ClassⅢ Grade A hospital from January to June 2017 were selected and they were evaluated at preoperative, intraoperative and postoperative stages. The area under the ROC curve of preoperative, intraoperative and postoperative three stages was calculated according to the scores, and the optimal diagnostic threshold and corresponding sensitivity and specificity were determined for the scores of each stage.Results:The evaluation form included preoperative, intraoperative and postoperative stages and 27 items. The scores of each stage were accumulated. The content validity index ( CVI) was 0.867, and inter-assessment consistency coefficients of pre-assessment, intra-operative and post-assessment assessments were 0.977, 0.927 and 0.900. The area under the ROC curve was 0.878, 0.911 and 0.918, and the best diagnostic cutoff values were respectively 14, 38, and 41. The corresponding sensitivities were 0.829, 0.805 and 0.865, and the specificities were respectively 0.832, 0.925 and 0.885. Conclusions:The assessment form has high consistency, sensitivity and specificity among assessors, which can realize dynamic assessment in stages and can be used as an effective tool for medical staff in the operating room to assess the risk of intraoperative pressure injury in adult patients undergoing orthopedic surgery.
