摘要
目的探讨改良早期预警评分(MEWS)在急诊晕厥患者分诊中的应用及准确性。方法以345例符合条件的急诊晕厥患者为研究对象,根据MEWS评分情况将患者分为紧急组(MEWS评分>4分)和非紧急组(MEWS评分≤4分),观察就诊24h内所发生的紧急事件。结果共有20例患者(5.9%)出现紧急事件,包括死亡6例,再次晕厥4例,呼吸循环骤停6例,入住ICU 6例。紧急组病死率(3.6%)和紧急事件总发生率(9.4%)明显高于非紧急组(0.5%、3.5%),差异有统计学意义(P>0.05)。MEWS评分预测紧急事件的灵敏度为65.0%,特异度为60.4%,阳性预测值为9.4%,阴性预测值为96.5%。结论改良早期预警评分在一定程度上有助于晕厥患者的分诊,但其准确度并不高,需要进一步研究和建立专门针对晕厥患者的分诊方法 。
Objective To evaluate the application of modified early warning score（MEWS） in triae of emergency patients with syncope. Methods Three hundred and forty five emergency patients with syncope were divided into emergency group （MEWS score〉4） and non- emergency group （MEWS score ≤4） . The urgent events were observed within 24h of emergency visit. Results Urgent events occurred in 20 cases （5.9%）, including 6 cases of death, 4 cases of recurrent syncope, 6 cases of respiratory and circulatory arrest and 6 cases of ICU admission. The mortality and the incidence of total urgent events in emer-gency group were significantly higher than those in non- emergency group. MEWS score predicted urgent events with a sensi-tivity of 65.0%, specificity of 60.4%, positive predictive value of 9.4%and negative predictive value of 96.5%. Conclusion Mod-ified early warning score contributes to triage of patients with syncope to some extent and further research and development of specialized triage methods for syncope patients is needed.
