The novel severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) or COVID-19 pandemic first arrived in Nashville, Tennessee, in early March 2020. Soon after, stay-at-home orders were initiated. The purpose of this study is to evaluate the impact of a 7-week lockdown on maxillofacial trauma volume at TriStar Skyline Medical Center, a level II trauma center in Nashville, Tennessee.
The investigator designed a retrospective cohort study and enrolled a sample of patients who presented for evaluation of maxillofacial trauma between March 23 and May 11 in the years 2019 and 2020. The primary predictor variable was evaluation of injures during the 2020 lockdown period or the same control period in 2019. The primary outcome variable was injury volume. Additional variables including demographic information, etiology, anatomic location, and initial disposition were evaluated. Descriptive and bivariate statistics were computed, with statistical significance set at P < .05.
The study sample showed a 35.6% reduction in patients seen during the 2020 lockdown (n = 38) compared with 2019 (n = 59, P = .15). The proportion of male to female trauma patients increased during the lockdown period from 6.6:1 (n = 33 male, n = 5 female) in 2020 compared with 2.3:1 (n = 41 male, n = 18 female) in 2019 (P = .049). The number of assaults decreased by 65.2% (P = .22). The percentage of patients seen on an outpatient basis decreased from 27.1% (n = 16) to 5.3% (n = 2, P = .007) during the lockdown period.
The initial 7-week lockdown during the COVID-19 pandemic was associated with a decrease in patients with maxillofacial trauma. The effect of the stay-at-home orders with resultant social distancing, has shown a decrease in maxillofacial trauma due to interpersonal violence.
新型严重急性呼吸综合征冠状病毒 2 型（SARS-CoV-2）或 COVID-19 大流行于 2020 年 3 月初首次抵达田纳西州纳什维尔。不久之后，就发布了居家令。本研究的目的是评估田纳西州纳什维尔二级创伤中心 TriStar Skyline 医疗中心的颌面创伤量在 7 周封锁期间的变化。
调查人员设计了一项回顾性队列研究，纳入了 2019 年和 2020 年 3 月 23 日至 5 月 11 日期间因颌面创伤就诊的患者样本。主要预测变量是 2020 年封锁期间或 2019 年同期的损伤评估。主要结局变量是损伤量。还评估了其他变量，包括人口统计学信息、病因、解剖部位和初始处置。计算了描述性和双变量统计数据，统计显著性设为 P<.05。
研究样本显示，2020 年封锁期间就诊患者减少 35.6%（n=38），而 2019 年就诊患者为 59 人（n=59，P=.15）。封锁期间男女创伤患者的比例从 2020 年的 6.6:1（n=33 名男性，n=5 名女性）增加到 2019 年的 2.3:1（n=41 名男性，n=18 名女性）（P=.049）。攻击事件减少了 65.2%（P=.22）。门诊就诊患者比例从封锁期间的 27.1%（n=16）下降至 5.3%（n=2，P=.007）。
COVID-19 大流行期间最初的 7 周封锁与颌面创伤患者减少有关。居家令导致的社交距离措施的影响，导致人际暴力所致颌面创伤减少。
