Abstract：Objective:To probe into the reliability and validity of two kinds of nonverbal pain assessment tools in evaluation of pain in critically ill patients.Methods:A total of 86 critically ill patients in ICU in a third grade A hospital were selected,and the patients’pain was evaluated by using the two kinds of Chinese version of nonve-rbal pain assessment tools under two different stimulations (non invasive blood pressure measurement,closed suction)at the same time,then respectively to collect the patients’pain score.The evaluation time included resting state,during operation,15~20 min after operation.Respectively at each time point 2 raters each hold an assessment tool to evaluate patients.For the conscious and matched patients,pain score was gained by a re-searcher by using NRS after pain stimualtion.Results:In the discriminant validity,the pain stimulations scores of two scales were higher than those in other evaluation process(P<0.001).In the criterion validity,the Pear-son correlation coefficient between BPS score and NRS score was 0.509,Pearson correlation coefficient between CPOT score and NRS score was 0.521 during pain stimulation operation.The sensitivity and specificity analysis showed that when the CPOT best pain node was 3.5,the sensitivity and specificity respectively were 70.0% and 60.5%,the gained area under the ROC curve(AUC)was 0.712;when the BPS best pain node was 7.5,the sen-sitivity and specificity respectively were 85.7% and 87.3%,the area under the ROC curve(AUC)was 0.843. Conclusion:Both BPS and CPOT had good reliability and validity,which could be used to assess the pain of crit-ically ill patients;In comprehensive analysis,the performance of BPS in pain diagnosis was better than that of the CPOT,but correlation between the CPOT and the patients’complained pain score(gold standard)was high-er than that of BPS.
