To explore the applicability of MuLBSTA Score in COVID-19 patients, a retrospective analysis was performed on 330 cases of COVID-19 patients in Southeast Hospital of Xiaogan City, Hubei Province. The clinical characteristics of COVID-19 patients were described and multilobe infiltrate in CT, bacterial infection, lymphocyte count, smoke in history, history of hypertension, and age distribution in the population of mild and severe patients were analyzed. All included patients were scored according to the MuLBSTA early warning scoring system and its efficacy in early warning of severe symptoms was analyzed. CT feature of infiltration changes on multiple lobes, the absolute value of lymphocyte count of less than 0.8 × 10⁹, accompanied by bacterial infection, history of smoking, history of hypertension, and an age of greater than 60 years old were all statistically significant factors in patients with severe COVID-19. ROC curve analysis indicated that the sensitivity, specificity and accuracy of the early warning system were 0.651, 0.954 and 0.93, respectively. The MuLBSTA Score has a good early warning effect on severe COVID-19 patients.

为探讨MuLBSTA评分在COVID-19患者中的适用性，对湖北省孝感市东南医院收治的330例COVID-19患者进行回顾性分析。描述了 COVID-19 患者的临床特征，并分析了 CT 多叶浸润、细菌感染、淋巴细胞计数、既往吸烟史、高血压病史以及轻度和重度患者人群的年龄分布。根据MuLBSTA早期预警评分系统对所有纳入患者进行评分，分析其对严重症状早期预警的疗效。CT表现为多叶浸润改变，淋巴细胞计数绝对值小于0.8×10 ⁹、伴有细菌感染、吸烟史、高血压病史、年龄大于60岁都是重症COVID-19患者具有统计学意义的因素。ROC曲线分析表明，该预警系统的灵敏度、特异度和准确度分别为0.651、0.954和0.93。MuLBSTA Score对重症COVID-19患者有很好的预警作用。
