调查轻度创伤性脑损伤（mTBI）患者的特征和住院结果。使用疾病分类国际编码（ICD）和文件记录的格拉斯哥昏迷评分（GCS）为13至15之间的1,940名mTBI患者，从2017年至2019年在7家社区医院中进行了识别。采用逐步Logistic回归分析，以确定与住院死亡和回家出院相关的人口统计学和临床特征。中位年龄为69岁，66.6%与入院时的跌倒相关。颅内血肿是最常见的脑损伤灶，而且在跌倒组中更为常见。年龄增长、男性性别、硬脑膜外出血、偏瘫、截瘫、肾脏疾病、癌症、院内感染、贫血和直接血管扩张剂的使用与住院死亡的增加几率相关。年龄增长、获得医疗保险的医疗保障、脑水肿、初始GCS较低、住院时间、急性心肌梗死的合并症、维生素B1和阿片类药物的使用与出院至家庭的可能性降低相关。认识住院mTBI患者的特征以及其与住院死亡和非回家出院的增加之间的关联，对改善这一脆弱人群的护理非常有用。版权所有 © 2023 Wolters Kluwer Health, Inc. 保留所有权利。

To investigate the characteristics and hospital outcomes of patients with mild traumatic brain injuries (mTBI).A total of 1,940 patients with mTBI from 7 community hospitals between 2017 and 2019 were identified using International Classification of Disease (ICD) codes and an documented initial Glasgow Coma Scale (GCS) score of 13 to 15. A stepwise logistic regression was used to identify demographics and clinical characteristics associated with in-hospital mortality and home discharge.The median age was 69 years old with 66.6% associated with falls at admission. Subdural hemorrhage was the most common brain lesion and more common in the group with falls. Increased age, male sex, epidural hemorrhage, presence of hemiplegia, paraplegia, renal disease, cancer, hospital-acquired sepsis, anemia, and use of direct vasodilator were associated with increased odds of in-hospital mortality. Increased age, medical coverage by Medicare, cerebral edema, lower initial GCS, length of stay, comorbidity of acute myocardiac infarction, and use of thiamine and opioids were associated with decreased likelihood of discharge to home.Recognizing characteristics of hospitalized patients with mTBI and their association with increased in-hospital mortality and non-home discharge can be useful for improving care of this vulnerable population.Copyright © 2023 Wolters Kluwer Health, Inc.
