Abstract：
Many social and behavioral changes occurred during the COVID-19 pandemic. Our objective was to identify changes in incidence of self-inflicted injuries during COVID-19 compared to prepandemic years. Further, we aimed to identify risk factors associated with self-inflicted injuries before and during the pandemic.
A retrospective cohort study of patients aged ≥18 y with self-inflicted injuries from 2018 to 2021 was performed using the Pennsylvania Trauma Outcome Study registry. Patients were grouped into pre-COVID Era (pre-CE, 2018-2019) and COVID Era (CE, 2020-2021). Statistical comparisons were accomplished using Wilcoxon rank-sum tests and chi-square or Fisher\'s exact tests.
There were a total of 1075 self-inflicted injuries in the pre-CE cohort and 482 during the CE. There were no differences in age, gender, race or ethnicity between the two cohorts. Among preexisting conditions, those within the pre-CE cohort had a higher incidence of mental/personality disorder (59.2% versus 52.3%, P = 0.01). There were no significant differences in the mechanism of self-inflicted injuries or place of injury between the two periods. Additionally, there were no differences in discharge destinations or mortality between the two cohorts.
During the height of social isolation in Pennsylvania, there were no associated increases in self-inflicted injuries. However, there were increased incidences of self-inflicted injuries among those with a prior diagnosis of mental or personality disorder in the pre-CE group. Further investigations are required to study the access to mental health services in future pandemics or public health disasters.

摘要：
背景：COVID-19大流行期间发生了许多社会和行为变化。我们的目标是确定与流行前期相比，COVID-19期间自我伤害发生率的变化。Further,我们的目的是确定在大流行之前和期间与自身伤害相关的危险因素.
方法：使用宾夕法尼亚创伤结局研究注册，对2018年至2021年年龄≥18岁的患者进行了回顾性队列研究。患者被分组为COVID前时代(CE前，2018-2019年）和COVID时代（CE，2020-2021）。使用Wilcoxon秩和检验和卡方检验或Fisher精确检验进行统计比较。
结果：CE前队列中共有1075例自我伤害，CE期间有482例。年龄没有差异,性别,两个队列之间的种族或种族。在先前存在的条件中，CE前队列中的人精神/人格障碍的发生率更高（59.2％对52.3％，P=0.01）。在两个时期之间，自我伤害的机制或伤害的位置没有显着差异。此外,两组的出院目的地和死亡率没有差异.
结论：在宾夕法尼亚州社会孤立的高峰期，自身造成的伤害没有相关的增加。然而,在CE前期诊断为精神或人格障碍的患者中,自我伤害的发生率增加.需要进一步调查，以研究未来大流行或公共卫生灾难中获得精神卫生服务的情况。
