目的对比分析改良早期预警(MEWS)评分系统与校正MEWS评分预测急性重症胰腺炎患者预后结局的准确性。方法选取2008年1月-2011年3月中南大学湘雅医院收治的急性重症胰腺炎患者61例,在医院接诊的同时分别进行MEWS评分和校正MEWS评分。观察患者30 d后的预后结局,比较2种评分系统对患者预后的预测差异。结果校正改良早期预警评分的预测符合率为91.8%,改良早期预警评分的预测符合率为67.2%,两者差异有统计学意义(P<0.05)。结论相比MEWS评分,校正MEWS评分更能反映急性重症胰腺炎患者的病情危重程度,预测病死率更加精确,建议在医院临床急诊工作中推广使用该方法。
Objective To compare the accuracy of MEWS and MEWS in predicting prognosis of patients with acute severe pancreatitis. Methods Sixty-one patients with acute severe pancreatitis admitted from Xiangya Hospital of Central South University from January 2008 to March 2011 were selected, MEWS score and MEWS score were respectively evaluated while hospital admissions. The prognosis of the patients after 30 days was observed, and the prognostic differences between the two scoring systems were compared. Results The coincidence rate of the predictive accuracy of the improved early warning score was 91.8%, and that of the improved early warning score was 67.2%. The difference was statistically significant (P <0.05). Conclusion Compared with the MEWS score, MEWS score can better reflect the severity of illness in patients with severe acute pancreatitis and predict the mortality more accurately. It is recommended to promote this method in the clinical emergency work of the hospital.
