NOBLADS与STRATE评分在下消化道出血患者应用价值的研究

比较 NOBLADS与STRATE这 2种评分系统对急性下消化道出血(ALGIB)预后的预测价值。方法 选取我院2016年3月-2021年12月东莞市人民医院收治的220例急性下消化道出血者为研究对象,采用NOBLADS与STRATE 这2种评分系统分别对患者危险程度进行评分,根据是否输血、再出血、再入院、死亡和是否接受干预进行分组,比较不同分组患者NOBLADS和STRATE评分,采用受试者工作曲线(Roc)分析NOBLADS和 STRATE评分预测患者是否输血、再出血、再入院、死亡和是否接受干预的价值。结果 根据两种评分系统评分为检验变量进行受试者工作特征曲线(ROC)分析,结果显示STRATE评分系统预测再出血、干预、再入院的 ROC 曲线下面积(AUC)依次为0.683、0.817、0.813;NOBLADS评分系统预测再出血、干预、再入院的 ROC 曲线下面积(AUC)依次为0.775、0.813、0.817。两种评分系统,在再出血、干预、再入院差异无统计学意义(P>0.05)。结论 NOBLADS与STRATE 评分可作为急性下消化道出血患者严重程度和预后评估指标。NOBLADS评分在再出血、干预、再入院预测价值较高,STRATE评分在干预、再入院预测价值较高.

Outline and Discussion of Patronising Acting as a Communicative Function

People always find themselves in a rather difficult situation when communicating with others. Quite often a seemingly good intention and caring manner in one's communication with others cannot guarantee the speaker that initiates the speech is rated as respectful and the communication as satisfying, let alone controlling and arrogant-like speech in a conversation. Patronising communication usually makes people fall into such a dilemma that they find it hard to carry out a successful interaction with other people. Researches in this aspect have been lauched to account for people's mental states during patronising communication, and Communication Accomodation Theory (CAT) are found to be the best to explain the situation. It is suggested that sensibility, consciousness together with empathy from the speaker and positive reactions such as humorous responses from the listener are the desirable skills in improving the quality of patronising communication.

Strate、NOBLADS和Oakland评分评价急性下消化道出血患者预后的价值

目的研究Strate、NOBLADS和Oakland评分系统在急性下消化道出血患者预后评估中的应用价值。方法选取2016年1月~2020年5月我院收治的213例急性下消化道出血患者,记录患者的临床资料,统计其Strate、NOBLADS和Oakland评分,根据是否为严重的下消化道出血、是否再出血、接受输血、死亡和是否接受内镜、介入或外科干预进行分组,比较不同分组患者Strate、NOBLADS和Oakland评分,采用受试者工作曲线(ROC)分析Strate、NOBLADS和Oakland评分预测患者发生严重的下消化道出血、再出血、输血、死亡和接受内镜、介入或外科干预的价值。结果严重的下消化道出血、死亡、输血、再出血患者的Strate、NOBLADS评分均高于非严重的下消化道出血、非死亡、非输血、非再出血的患者,差异有统计学意义(P<0.05),但在是否接受干预方面,差异无统计学意义(P>0.05);严重的下消化道出血、输血、再出血、接受干预患者的Oakland评分均高于非严重的下消化道出血、非输血、非再出血及未接收干预患者,差异有统计学意义(P<0.05),在是否死亡方面,差异无统计学意义(P>0.05);ROC曲线显示,Strate、NOBLADS和Oakland评分预测是否为严重出血的AUC分别为0.852、0.787、0.883;预测再出血的AUC分别为0.701、0.702、0.724;预测输血的AUC分别为0.802、0.822、0.903;预测死亡的AUC分别为0.822、0.854、0.762。结论Strate、NOBLADS和Oakland评分可作为急性下消化道出血患者严重程度和预后评估指标,Oakland评分预测严重程度和输血需求价值较高,NOBLADS评分预测患者死亡结局的价值较高。
