Abstract：
UNASSIGNED: In 2020, the coronavirus disease 2019 (COVID-19) pandemic caused the cessation of nonemergent total joint arthroplasty (TJA, referring to total hip and total knee arthroplasty) operations between mid-March and April 2020. The purpose of this study is to analyze the effects and potential disparities in access to care due to the COVID-19 restrictions.
UNASSIGNED: A database was used to examine the demographics of patients undergoing TJA from May to December 2019 (pre-COVID-19) and from May to December 2020 (post-COVID-19 restrictions). Categorical covariates were summarized by reporting counts and percentages and compared using Fisher exact tests. Continuous covariates were summarized by reporting means and standard deviations. Two-sample t-tests were used for continuous covariates. The equality of TJA counts by year was tested using a test of proportions.
UNASSIGNED: There were more TJA procedures performed during the post-COVID-19 period in 2020 than in the pre-COVID-19 period (1151 vs 882, P < .001). There was an increase in the relative percentage of THAs vs TKAs performed in 2020 vs 2019 (26.9% vs 18.8%, P < .001) and an increase in patients with Medicaid with a decrease in private insurance (P = .043). The average length of stay was shorter in 2020 with a greater percentage of TJAs performed outpatient (P < .001). There were no differences in patient sex, race, body mass index, smoking status, or age between the 2 periods.
UNASSIGNED: A relative increase in THA procedures, an increase in patients with Medicaid and decrease in private insurance, and a a decreased length of stay were seen after COVID-19 restrictions. These trends may reflect pandemic-related changes in insurance status as well as the growing shift to same-day discharge.

摘要：
未经批准：2020年，COVID-19大流行导致非紧急全关节成形术停止（TJA，指全髋关节和全膝关节置换术)2020年3月中旬至4月之间的手术。这项研究的目的是分析由于COVID-19限制而在获得护理方面的影响和潜在差异。
UNASSIGNED：使用一个数据库检查了2019年5月至12月（COVID-19之前）和2020年5月至12月（COVID-19之后的限制）接受TJA的患者的人口统计学。分类协变量通过报告计数和百分比进行总结，并使用Fisher精确检验进行比较。通过报告平均值和标准偏差来总结连续协变量。双样本t检验用于连续协变量。使用比例测试来测试按年份的TJA计数的相等性。
未经评估：2020年与COVID19之前相比，在COVID-19之后期间执行了更多的TJA程序（1151与882,p<.001)。THA的相对百分比与TKAs在2020年与2019年的表现（26.9%对18.8%，p<.001),医疗补助患者增加，私人保险减少（p=.043）。2020年的平均住院时间较短，门诊的TJAs比例更高（p<.001）。患者性别没有差异，种族,BMI,吸烟状况,或两个时期之间的年龄。
未经批准：THA程序相对增加，医疗补助患者的增加和私人保险的减少，在COVID-19限制后，住院时间缩短。这些趋势可能反映了与大流行相关的保险状况的变化，以及越来越多地转向当日出院。
