MEWS评分在急诊留观患者护理决策中的应用

Application of modified early warning score （ MEWS） on the nursing care of the patients in Emergency Observation Room

目的 探讨改良早期预警评分（MEWS）在急诊留观患者护理决策应用及其转归与预后中的关系.方法 采用便利取样的方法,对某三级甲等医院的331例急诊留观患者进行MEWS评分,分析患者入室MEWS评分与留观天数的相关性,留观3 d后的MEWS评分与患者去向的相关性.结果 患者入室MEWS评分与留观天数、患者去向无相关性（r值分别为0.052,0.097;P〉0.05）;患者入室第3天MEWS评分与患者去向及转归存在相关性（r=0.550,P〈0.05）;MEWS分值越高,患者病情越严重,病死率越高.结论 MEWS评分可用于急诊留观患者的病情观察及预测患者的预后和转归,有助于护理人员制订护理决策,为相关研究的进一步开展提供理论依据.

Objective To investigate the application of modified early warning score （ MEWS） to the nursing care of the patients in Emergency Observation Room, and to explore the relationship between outcome and prognosis. Methods According to the convenience sampling method, 331 patients in Emergency Observation Room from a grade A tertiary hospital were assessed by MEWS. The observation factors included the relationship between MEWS at the first day of entering the room and patients′ observation time, MEWS after three days and prognosis. Results Patients′ MEWS at the first day had no correlation with observation time or prognosis （ r=0.052,0.097;P〉0.05）; patients′ MEWS after three days was related to prognosis（r =0.550, P〈0.05）. Moreover, the higher MEWS implied the worse conditions and higher mortality. Conclusions MEWS can imply patients′illness outcome and prognosis in order to help nurses to make nursing decision.
