目的：探讨改良早期预警评分（ MEWS）在院前急救患者病情评诂中的应用效果。方法：将我院120急救的2150例患者应用现场MEWS方法，对患者不同分数段的病情严重程度、分布特征、院前紧急处理进行分析，评估患者的预后及病情转归。结果：2150例改良早期预警评分评估0～4分段1134例，400例（35．2％）院前一般处理；5～9分段656例，621例（94．7％）以院前一般处理为主；≥10分段360例，326例以院前紧急处理为主，三分数段比较差异有统计学意义（P＜0．05）；MEWS评分0～4分数段中以好转离院和急诊留观为主，5～9分数段以转入专科病房治疗为主（69．5％），≥10分以转入专科病房及ICU 为主（89．4％），三分数段比较差异有统计学意义（P＜0．01）。结论：院前急救患者应用MEWS进行评估，MEWS分数与病情严重程度呈正相关，当MEWS≥5分时，应严密监护，及早进行防治措施，可提升抢救成功率，降低病死率。%Objective:To investigate the application effect of the modified early warning scoring methods to the evaluation on the condi -tions of the patients undergoing pre hospital first aid .Methods:The modified early warning scoring methods were used to analyze the severi-ty of patient's condition in different scores ,distribution characteristics and pre hospital emergency treatment of 2150 patients rescued by 120 first aid system, and the outcome and prognosis of the patients were evaluated .Results:In 2150 patients,1134 patients were evaluated from 0~4 points and 400 of them (35.2%) were given general pre hospital emergency treatment;656 patients from 5~9 points and 621 of them (94.7%) were given pre hospital emergency treatment;360 patients≥10 points and 326 of them were given pre hospital emergency treatment ( P<0.05);the patients evaluated from 5~9 points were transferred to special ward for treatment (69.5%);the patients ≥10 were respectively transferred to special ward and ICU for treatment (89.4%) and the difference was statistically significant (P<0.01). Conclusion:The modified early warning scores were positively correlated to the severity of patient 's condition .The patients should be given close moritoring when the modified early warning scores≥5 points,thus the success rate of rescue will be increased .
