OBJECTIVES
to identify the association of the National Early Warning Score (NEWS2) and NEWS Age with risk categories, severity markers and outcomes in the emergency department.
METHODS
retrospective cohort study, conducted in a high-complexity hospital, with 356 hospitalized patients (mean age 59.4; ±14.4 years) with COVID-19, from April to August 2020. To verify the association between risk categories and alert scores, the chi-square, Kruskal-Wallis and likelihood ratio tests (p<0.05) were used.
RESULTS
patients stratified in the red category had higher NEWS2 and NEWS Age (<0.0001) than the others. Clinical risk categorized by scores was associated with clinical deterioration (p<0.0001), orotracheal intubation (p<0.0001) and death (NEWS - p=0.0098/NEWS Age - p<0.0001).
CONCLUSIONS
scores ≥ 7 were associated with red/orange risk stratification, clinical deterioration and occurrence of death.
目的
确定国家早期预警评分（NEWS2）和NEWS年龄与急诊科风险类别、严重程度指标及预后之间的关联。
方法
在一家高复杂性医院进行回顾性队列研究，研究对象为2020年4月至8月期间356例确诊为新冠肺炎的住院患者（平均年龄59.4岁；±14.4岁）。为验证风险类别与预警评分之间的关联，采用了卡方检验、Kruskal-Wallis检验和似然比检验（p<0.05）。
结果
分层为红色类别的患者NEWS2和NEWS年龄高于其他类别（<0.0001）。按评分分类的临床风险与临床恶化（p<0.0001）、气管插管（p<0.0001）和死亡（NEWS - p=0.0098/NEWS年龄 - p<0.0001）相关。
结论
评分≥7与红色/橙色风险分层、临床恶化及死亡发生相关。
