This Healthcare Cost and Utilization Project (HCUP) Statistical Brief presents statistics on initial and subsequent TBI-related inpatient stays and treat-and-release emergency department (ED) visits (i.e., those that do not result in admission to the same hospital) using the 2017 National Inpatient Sample (NIS) and the 2017 Nationwide Emergency Department Sample (NEDS). Readmission rates following inpatient stays for TBI-related injuries also are presented using the 2017 Nationwide Readmissions Database (NRD). TBIs are categorized as those involving cerebral hemorrhage; mild to severe TBIs without cerebral hemorrhage, but that involve injuries more complex than concussion (e.g., cerebral edema); and uncomplicated concussion. First, patient and injury-related characteristics of inpatient stays and ED visits with any TBI diagnosis (principal or secondary) are shown. Second, outcomes of inpatient stays with a principal diagnosis of TBI are described, including length of stay, average cost per stay, and rates of in-hospital mortality and all-cause 30-day readmissions. Because of the large sample size of the HCUP NIS, NEDS, and NRD small differences can be statistically significant. Thus, only differences between groups greater than or equal to 10 percent are noted in the text.
本医疗成本与利用项目（HCUP）统计简报呈现了有关创伤性脑损伤（TBI）相关初次及后续住院治疗以及急诊室（ED）治疗并出院就诊情况（即未导致同一家医院收治的就诊情况）的统计数据，数据来源于2017年全国住院患者样本（NIS）和2017年全国急诊室样本（NEDS）。还使用2017年全国再入院数据库（NRD）呈现了TBI相关损伤住院治疗后的再入院率。创伤性脑损伤分为以下几类：涉及脑出血的创伤性脑损伤；无脑出血的轻至重度创伤性脑损伤，但涉及比脑震荡更复杂的损伤（如脑水肿）；以及单纯性脑震荡。首先，展示了任何TBI诊断（主要或次要）的住院治疗和急诊室就诊的患者及损伤相关特征。其次，描述了主要诊断为TBI的住院治疗结果，包括住院时长、每次住院的平均费用、院内死亡率以及全因30天再入院率。由于HCUP NIS、NEDS和NRD样本量较大，微小差异在统计学上可能具有显著性。因此，文本中仅注明了组间差异大于或等于10%的情况。
