Abstract: Objective To compare and evaluate the prediction effect of Intraoperatively Acquired Pressure Injury Risk Assessment Scale, Braden Pressure Injury Risk Assessment Scale and the Munro Assessment Scale for pressure injury risk in adult patients with selective operations, and to provide reference for appropriate scale of clinical practice. Methods A total of 237 patients with selective operations from December 2019 to June 2020 were selected from two tertiary, grade A hospitals and they were surveyed by using the three scales to assess the risk of pressure injury and skin examination for each patient before, during and after the surgery. The prediction effect and operation convenience of the three scales were analyzed and compared. Results For intraoperatively acquired pressure injury risk assessment scale, Braden pressure injury risk assessment scale and the Munro assessment scale for pressure injury risk, the AUC of preoperative area under the ROC curve of the three scale during perioperative period was 0.695, 0.619 and 0.684, respectively; that was 0.848, 0.633 and 0.882, respectively during the surgery and that after the operation was 0.861, 0.757 and 0.870, respectively. By comparing the assessment time of the three scales, the assessment time of intraoperatively acquired pressure injury risk assessment scale was the shortest. Conclusion The intraoperatively acquired pressure injury risk assessment scale has good predictive effect in patients with surgical acquired pressure injury. It is convenient and worthy of clinical application.
