Abstract  Objective To compare the predictive effects of Braden, COMHON, Cubbin & Jackson scales on pressure injury in intensive care unit (ICU) patients after cardiopulmonary bypass, and to screen the best predictive tool for pressure injury risk in such patients. Methods The Braden scale, COMHON scale, and Cubbin & Jackson scale were used to assess the risk of pressure injury in 252 patients admitted to a tertiary hospital after cardiopulmonary bypass from September 2017 to February 2019. The predictive power of the three scales for pressure injury occurring within seven days was compared. Results Among 252 ICU patients after cardiopulmonary bypass, 150 patients developed pressure injury within seven days, and 102 patients did not develop pressure injury. There were significant differences in disease type, acute physiology and chronic health evaluationⅡ score and mechanical ventilation time between the two groups (P < 0.05). Comparison of the predictive ability of the three scales: the Braden scale for predicting the occurrence of pressure injury in patients after cardiopulmonary bypass in the ICU with a critical value of 10 points, the area under the receiver operating characteristic curve (AUC), sensitivity, specificity, and positive likelihood ratio, the negative likelihood ratios were 0.512, 29.33%, 74.51%, 1.149, 0.948, and 0.523; the critical value of COMHON scale for predicting the occurrence of pressure injury in patients after cardiopulmonary bypass in ICU was 17 points, and its AUC, sensitivity, specificity, positive likelihood ratio, and negative likelihood ratio were 0.523, 30.67%, 80.39%, 1.564, 0.862, respectively; the critical value of the Cubbin & Jackson scale for predicting the occurrence of pressure injury in patients after cardiopulmonary bypass in the ICU was 25 points, and its AUC, sensitivity, specificity, positive likelihood ratio, and negative likelihood ratio were 0.687, 64.67%, 64.71%, 1.837, 0.546. There was a statistically significant difference in the scores of inotropic drugs between the two groups (P < 0.05). Conclusion The Cubbin & Jackson scale in more suitable than the Braden scale and the COMHON scale to predict pressure injury in patients after cardiopulmonary bypass in the ICU.
