The study of application of the Critical Care Pain Observation Tool among medical patients with mechanical ventilation / 中国实用护理杂志

ABSTRACT

Objective To evaluate the applicability of the Critical Care Pain Observation Tool (CPOT) in medical patients with mechanical ventilation. Methods A descriptive design was chosen for this study. A convenience sample of 110 medical patients with mechanical ventilation in ICU was selected, among which, 53 cases were sober (including 34 patients with pain and 19 patients without pain), 57 cases were non-sober. The CPOT was applied for evaluating the reliability, validity, reactive degree, sensitivity, specificity and ROC curve analysis. Results Cronbach alpha coefficient was 0.865. Intraclass correlation coefficient was 0.883. CVI was 1.00. Spearman correlation with Visual Analogue Scale (VAS) was 0.544. In known-group technique, only pain score was statistically significant in Ramsay score. In reactive degree, score was statistically significant in three testing points. The CPOT had a sensitivity of 94.1％and a specificity of 46.7％. The area under the ROC curve was 0.716. Conclusions The CPOT has good internal consistency, interrater reliability, content validity, reactivity, moderate criterion validity. Speciality in distinguishing pain and other symptoms is worse. Future research is warranted to further verify the applicability of the CPOT.
