Abstract:
Objective:To develop the Peristome Skin Injury Risk Assessment Scale and to verify its reliability, validity and predictive performance in patients with colorectal cancer stoma.Methods:The initial assessment scale was developed through literature review and Delphi expert consultation. From February 2020 to April 2021, convenient sampling was used to select 290 cases of colorectal cancer stoma patients who were reexamined in the Oncology Surgery of the First Affiliated Hospital of Xi'an Jiaotong University as the research object. Item analysis, validity analysis, reliability analysis, receiver operating characteristic curve (ROC) were used to test the reliability, validity and predictive performance of the scale.Results:Exploratory factor analysis extracted a total of 4 common factors, namely general condition, stoma condition, postoperative condition, education and self-care condition, a total of 17 items, and the cumulative variance contribution rate was 85.144%. The scale-level content validity index was 0.941, and the item-level content validity index was 0.857 to 1.000. The Cronbach's α coefficient of the total scale was 0.824, the split-half reliability coefficient was 0.837, and the test-retest reliability coefficient was 0.819. There was a statistically significant difference in the scores of the Peristome Skin Injury Risk Assessment Scale in patients with colorectal cancer stoma between the injury group and the non-injury group ( P<0.05) . The area under the ROC curve was 0.838 (95% confidence interval: 0.785-0.891) . When the cut-off score was 39.5, the sensitivity of the scale was 0.849, the specificity was 0.759, the Youden index was 0.608, and the predictive performance was the best. Conclusions:The Peristome Skin Injury Risk Assessment Scale has good reliability and validity, and has high predictive performance, which is suitable for the assessment of the risk of peristome skin injury in patients with colorectal cancer in China.
