摘要: 目的:比较AIMS65与Blatchford评分系统对于上消化道出血(UGIB)患者死亡、再出血、输血及内镜下治疗的预测价值。方法:选择青岛市第八人民医院消化内科2013年1月—2019年6月收治的486例UGIB患者,对其临床资料进行回顾性分析,分别采用AIMS65与Blatchford评分对患者进行评分,利用受试者工作特征(ROC)曲线下面积比较两种评分对于UGIB患者死亡、再出血、输血及内镜下治疗的预测价值。另外,采用AIMS65评分分别对非静脉曲张性和静脉曲张性UGIB患者进行评分,评估AIMS65评分对于两组患者预后的预测价值。结果:在486例UGIB患者中,死亡33例,再出血55例,输血268例,内镜下治疗91例。随着AIMS65、Blatchford评分的增加,UGIB患者的死亡率、再出血率、输血率及内镜下治疗率均相应增加。AIMS65评分预测UGIB患者死亡、再出血、输血及内镜下治疗的ROC曲线下面积分别为0.870(95%CI:0.837~0.899)、0.642(95%CI:0.598~0.685)、0.673(95%CI:0.629~0.714)、0.553(95%CI:0.508~0.598),而Blatchford评分分别为0.717(95%CI:0.675~0.757)、0.755(95%CI:0.714~0.793)、0.764(95%CI:0.723~0.801)、0.662(95%CI:0.618~0.704)。另外,AIMS65评分预测非静脉曲张性UGIB患者死亡、再出血、输血及内镜下治疗的ROC曲线下面积分别为0.810(95%CI:0.764~0.850)、0.649(95%CI:0.598~0.693)、0.592(95%CI:0.545~0.631)、0.547(95%CI:0.501~0.591),预测静脉曲张性UGIB患者的ROC曲线下面积分别为0.917(95%CI:0.862~0.973)、0.838(95%CI:0.746~0.893)、0.768(95%CI:0.729~0.805)、0.727(95%CI:0.687~0.764)。结论:对于UGIB患者,AIMS65评分对死亡的预测价值明显优于Blatchford评分,对内镜下治疗的预测能力较差;而Blatchford评分对再出血、输血及内镜下治疗的预测价值优于AIMS65评分。另外,对于静脉曲张性UGIB患者,AIMS65评分均有较好的预后评价能力;而对于非静脉曲张性UGIB,AIMS65评分预测死亡、再出血的价值较高。Abstract: Objective: To compare the predictive value of AIMS65 and Blatchford score for mortality, rebleeding, blood transfusion and endoscopic intervention of patients with upper gastrointestinal bleeding(UGIB).Methods: A retrospective cohort study was performed in 486 patients who attended the Gastroenterology department of Qingdao Eighth People's Hospital with UGIB from Jan. 2013 to Jun. 2019. The AIMS65 and Blatchford score were calculated for all patients respectively. The rates of mortality, rebleeding, blood transfusion and endoscopic intervention and their areas under the receiver operating characteristic(ROC) curve were calculated to verify the predictive value. In addition, for the patients with variceal and nonvariceal UGIB, the AIMS65 score was calculated to assess the predictive value.Results: Of the 486 patients with UGIB, 33 died, 55 experienced rebleeding, 268 received blood transfusion, and 91 experienced endoscopic intervention. The areas under ROC curve of AIMS65 for mortality, rebleeding, blood transfusion and endoscopic intervention were 0.870(95%CI: 0.837-0.899), 0.642(95%CI: 0.598-0.685), 0.673(95%CI: 0.629-0.714) and 0.553(95%CI: 0.508-0.598), respectively. The areas under ROC curve of Blatchford score were 0.717(95%CI: 0.675-0.757), 0.755(95%CI: 0.714-0.793), 0.764(95%CI: 0.723-0.801) and 0.662(95%CI: 0.618-0.704), respectively. The areas under ROC curve of AIMS65 in predicting mortality, rebleeding, blood transfusion and endoscopic intervention of patients with nonvariceal UGIB were 0.810(95%CI: 0.764-0.850), 0.649(95%CI: 0.598-0.693), 0.592(95%CI: 0.545-0.631) and 0.547(95%CI: 0.501-0.591), respectively. The areas under ROC curve of AIMS65 in predicting mortality, rebleeding, blood transfusion and endoscopic intervention of patients with variceal UGIB were 0.917(95%CI: 0.862-0.973), 0.838(95%CI: 0.746-0.893), 0.768(95%CI: 0.729-0.805) and 0.727(95%CI: 0.687-0.764), respectively.Conclusion: For UGIB, the AIMS65 score is superior to the Blatchford score to predict mortality, whereas the Blatchford score is superior for predicting rebleeding, blood transfusion and endoscopic intervention. And the AIMS65 score can predict the outcomes of patients with variceal UGIB, and can predict the mortality, rebleeding of patients with nonvariceal UGIB.
