Syncope is a temporary loss of consciousness usually related to insufficient blood flow to the brain. It's also called fainting or "passing out." Syncope is responsible for 3% to 5% of emergency department visits, with a hospitalization rate in about 40% of cases, with an average stay of 5.5 days. The Canadian Syncope Risk Score showed good discrimination and calibration for 30-day risk of serious adverse events after disposition from the emergency department.The aim was to assess Canadian Syncope Risk Score in predicting outcomes and mortality at the emergency department of Suez Canal University Hospitals.A prospective observational cohort study was carried out in emergency department in Suez Canal University Hospital. After approval by the Ethical and Research Committee of Faculty of Medicine, Suez Canal University, 60 patients with syncope attending to emergency department were included to this study. All included participants were assessed by history taking and they also assessed by the Canadian Syncope Risk Score.The Canadian Syncope Risk Score's mean of the study group was 4.9 and the range of the scores was from -2 to 11. The mean of the percentage of risk of serious events at 30 days in the study group was 29.17% and it ranged from 0.7% to 83.6%.There was a statistically significant difference between means Canadian Syncope Risk Score's score regarding complication occurrence. Cases which showed complications had a mean score of 7.33 compared to a mean score of 1.25 in case of no complication occurrence P-value <.001. At a cut-off point of more than 3 for the Canadian Syncope Risk Score's, sensitivity of that score in complication's occurrence prediction was 100% and the specificity was 87.5% P-value <.001.The Canadian Syncope Risk Score's is strong predictor for risk of serious adverse events and a good indicator for admission, with 100% sensitivity and 87.5% specificity at cut off point more than 3.
晕厥是一种短暂的意识丧失，通常与大脑血液供应不足有关。它也被称为昏厥或“昏倒”。晕厥占急诊科就诊的 3%至 5%，住院率约为 40%，平均住院时间为 5.5 天。加拿大晕厥风险评分（Canadian Syncope Risk Score）在急诊科处置后 30 天内发生严重不良事件的风险方面具有良好的区分度和校准度。本研究旨在评估加拿大晕厥风险评分（Canadian Syncope Risk Score）在预测苏伊士运河大学医院急诊科结局和死亡率方面的作用。
这是一项前瞻性观察性队列研究，在苏伊士运河大学医院急诊科进行。在苏伊士运河大学医学院伦理和研究委员会批准后，纳入了 60 名因晕厥就诊于急诊科的患者。所有纳入的参与者均接受了病史采集，并接受了加拿大晕厥风险评分评估。
研究组的加拿大晕厥风险评分均值为 4.9，评分范围为-2 至 11。研究组 30 天内严重事件风险百分比的均值为 29.17%，范围为 0.7%至 83.6%。
加拿大晕厥风险评分的均值与并发症的发生有统计学显著差异。出现并发症的病例评分均值为 7.33，而无并发症发生的病例评分均值为 1.25，P 值<0.001。当加拿大晕厥风险评分大于 3 分时，该评分对并发症发生的预测敏感性为 100%，特异性为 87.5%，P 值<0.001。
加拿大晕厥风险评分是严重不良事件风险的强预测指标，也是入院的良好指标，截断值大于 3 时，敏感性为 100%，特异性为 87.5%。
