Objective:
To evaluate the predictive validity of the Cubbin & Jackson scale and the COMHON index in intensive care units in China.
Methods:
This study was conducted in the intensive care unit of a tertiary grade A hospital in Shenzhen, China, from February 2022 to December 2023. Two senior nurses independently performed each assessment using both the Cubbin & Jackson scale and the COMHON index simultaneously. Baseline characteristics were collected at the first evaluation. Sensitivity, specificity, positive and negative predictive value, Youden Index, and the area under the curve of the receiver operating characteristic were used to compare the predictive performance.
Results:
A total of 253 patients were included in the evaluation, out of which 25 patients developed pressure injuries. The cut-off score of 32 for the Cubbin & Jackson scale and 9 for the COMHON index demonstrated the highest predictive validity. The sensitivity, specificity, positive and negative predictive value, Youden Index, and area under the curve of the receiver operating characteristic were determined to be 100%, 63.89%, 21.21%, 100%, 0.64, and 0.88, respectively, for the Cubbin & Jackson scale. Similarly, the COMHON index exhibited values of 100%, 64.58%, 21.54%, 100%, 0.65, and 0.80 for the same parameters.
Conclusions:
The Cubbin & Jackson scale and the COMHON index demonstrated comparable moderate predictive efficacy in assessing pressure injury risk among patients in the intensive care unit.
