目的:比较改良早期预警评分(MEWS)与校正改良早期预警评分(MEWS)预测急性左心衰预后结局的准确性,为急性左心衰在急诊救治中寻找一种有效简易的病情评估方法。方法:选择2012年3月~2013年12月我院收治的确诊急性左心衰患者100例作为研究对象,在我院接诊时同时进行MEWS评分和校正MEWS评分;观察并比较2种评分系统对患者预后结局的预测准确性差异。结果:MEWS评分和校正MEWS评分的符合率分别为69.0%和92.0%,差异显著。结论:校正MEWS评分较MEWS评分更能够反映急性左心衰患者的病情危重程度,而且操作简便、预测精确,建议在临床急诊中推广。
OBJECTIVE: To compare the accuracy of modified early warning score (MEWS) with corrected modified early warning score (MEWS) to predict prognosis of acute left heart failure and to find an effective and simple condition evaluation method for emergency treatment of acute left heart failure. Methods: From March 2012 to December 2013, 100 patients diagnosed as acute left heart failure admitted to our hospital from March 2012 to December 2013 were enrolled in this study. MEWS and MEWS scores were evaluated simultaneously in our hospital. Two scoring systems were observed and compared. Accuracy of prognosis of patients with prognosis. Results: The coincidence rates of MEWS score and MEWS score were 69.0% and 92.0%, respectively, with significant differences. Conclusion: The corrected MEWS score is more able to reflect the critical illness severity of patients with acute left heart failure than the MEWS score. It is also easy to operate and accurate in prediction. It is recommended to be used in clinical emergency.
