Abstract:

Objective To compile and test the reliability and validity of the risk factor assessment scale for intraoperative acquired pressure injury,aiming to provide a scientific and objective stress injury assessment tool for operating room nurses. Methods The first draft of the scale is formed by 2 rounds of Delphi method on the basis of evidence. The convenience sampling was adopted to select 6 713 surgical patients from November 2019 to January 2020,covering 7 hospitals in 7 major regions of East China,South China,Central China,North China,Northeast China,Southwest China,and Northwest China for clinical multi-center research. The reliability and validity of the risk factor assessment scale for intraoperative acquired pressure injury were tested and the ROC curve was drawn. Results The risk factor assessment scale for intraoperative acquired pressure injury includes 10 items in 2 dimensions. The positive coefficients of 2 rounds of letter consultations were 100%;the authority coefficients were 0.874 and 0.885;the coordination coefficients were 0.164 and 0.170. The overall Cronbach’s α coefficient of the scale was 0.648;the half-reliability was 0.705;the content validity was 0.989. The ROC curve was used to determine the critical value of the preoperative and intraoperative. The cut-off value of the risk factor assessment scale for acquired pressure injury were 8.5 and 7.5,and the area under the curve were 0.779 and 0.776. Conclusion The risk factor assessment scale for intraoperative acquired pressure injury in Chinese inpatients has good reliability and validity and it can be used in clinical practice widely.
