【目的】研究改良早期预警评分（MEWS）在急诊分诊管理中的应用价值。【方法】随机选取2013年5月至2014年4月本院急诊患者560例随机分为对照组和观察组，每组各280例。对照组患者按常规的急诊分诊预检法，观察组患者采用M EWS系统，按评分结果分级处置，比较两种分诊方法在急诊患者分诊中的准确率以及两组患者满意度。【结果】观察组分诊准确率为95．0％（266／280），患者满意度为94．6％（265／280），两者均明显高于对照组的90．7％（254／280）和88．9％（249／280），且两组相比较差异有显著性（χ2＝3．88和6．06，P均＜0．05）。【结论】MEWS可以提高急诊分诊的准确性，患者更为满意，值得推广。“,”[Objective] To explore the application value of modified early warning score (MEWS) in the management of emergency triage .[Methods] At our emergency department from May 2013 to April 2014 ,a total of 560 patients were divided into control ( n = 280) and observation ( n = 280) groups .The control group was triaged conventionally while the observation group applied MEWS .And the patients received treat‐ment of different levels according to the scores .The triage accuracy of two groups and satisfaction rate for two systems were compared .[Results] The rates of accurate triage rate and satisfaction in observation group (95 . 0% ,94 .6% ) was significantly higher than that of control group (90 .7% ,88 .9% )(χ2 =3 .88 ,6 .06 ,either P<0 .05) .[Conclusion] MEWS evaluation allows a more accurate triage of patients .And it is worthy of wider popularization in emergency department .
