【摘要】 目的分析中文版PRE-DELIRIC谵妄预测模型在ICU患者中的信度和效度。方法选取306例ICU患者作为样本,使用PRE-DELIRIC谵妄预测模型对其施测以行评价者间信度分析和预测效度分析。结果使用PRE-DELIRIC谵妄预测模型时,评价者间的信度为0.94(P<0.01);预测效度结果表明,当PRE-DELIRIC谵妄预测模型的阈值取42%时,灵敏度为0.848,特异度为0.946,ROC曲线下面积为0.936(95%CI:0.910~0.963)(P<0.001)说明工具具有较好的预测效度。结论 PRE-DELIRIC的评价者间信度和预测效度较好,适合对ICU患者进行谵妄发生的预测。更多还原

【Abstract】 Objective To analyze the reliability and validity of Chinese version of PRE-DELIRIC delirium prediction model for ICU patients.Method 306 patients in ICU was selected for the study.The reliability and predictive validity analysis and evaluation was conducted by using PRE-DELIRIC delirium predictive models.Result Using the PRE-DELIRIC delirium prediction model,the inter-rater reliability was 0.94(P<0.01).The predictive validity results show that when the threshold values of PRE-DELIRIC delirium prediction model was 42%,the sensitivity was0.848,the specificity was 0.946,the area under the ROC curve was 0.936(95%CI:0.910~0.963)(P<0.001).It’s showed that the tool has good predictive validity.Conclusion The PRE-DELIRIC between evaluators has good reliability and predictive validity.It’s suitable for predicted delirium occurred for ICU patients.更多还原
