The purpose of this study was to undertake a retrospective cross-sectional analysis to compare the frequency and characteristics of facial injury presentations at a UK and an Australian tertiary referral hospital during the implementation of COVID-19 social-distancing measures. The primary predictor variables were a heterogeneous set of factors grouped into logical categories: demographics, injury mechanisms and site, and management. The primary outcome variable was the presentation of a hard or soft tissue facial injury. A descriptive statistical analysis was undertaken on the assembled data. The study found a clinical and statistically significant reduction in the frequency (absolute number) of facial injuries at each study site. In addition, a striking similarity common in both countries was an increase in the number of facial injuries due to falls and a reduction in facial injuries due to interpersonal violence. Conservative (non-operative) management of facial injury increased at both sites. The implementation of COVID-19 social-distancing public health measures, which aimed to limit community transmission of the coronavirus, had a secondary serendipitous effect of reducing the frequency of facial injury presentations and altering their epidemiological characteristics at both a UK and Australian tertiary referral hospital.
本研究旨在进行回顾性横断面分析，比较在 COVID-19 社交距离措施实施期间，一家英国和一家澳大利亚三级转诊医院面部损伤就诊的频率和特征。主要预测变量是一组异质因素，分为逻辑类别：人口统计学、损伤机制和部位以及处理方法。主要结局变量是硬组织或软组织面部损伤的表现。对收集的数据进行了描述性统计分析。研究发现，每个研究地点的面部损伤就诊频率（绝对数量）均呈临床和统计学显著下降。此外，两个国家都有一个显著的共同点，即跌倒导致的面部损伤数量增加，而人际暴力导致的面部损伤数量减少。两个地点的面部损伤保守（非手术）管理都有所增加。旨在限制冠状病毒社区传播的 COVID-19 社交距离公共卫生措施的实施，产生了次要的意外效果，即减少了英国和澳大利亚三级转诊医院的面部损伤就诊频率，并改变了其流行病学特征。
