Abstract：
UNASSIGNED: The COVID-19 pandemic substantially disrupted healthcare utilization patterns, globally. South Korea had been praised widely in its efforts to contain the spread of the pandemic, which may have contributed to a significantly smaller reduction in healthcare utilization compared to neighboring countries. However, it remains unknown how the COVID-19 pandemic impacted utilization patterns across population sub-groups, particularly vulnerable patient groups in South Korea. This paper quantifies the changes in healthcare utilization attributable to COVID-19 and the COVID-19 vaccination by sub-groups.
UNASSIGNED: An interrupted time series analysis was conducted to examine the impact of COVID-19 on healthcare utilization in South Korea from January 2016 to December 2022 using aggregated patient-level data from the national health insurance system that accounts for 99% of all healthcare services in South Korea. We applied negative binomial models adjusting for seasonality and serial correlation. Falsification tests were conducted to test the validity of breakpoints. Stratified analyses by type of healthcare services, age, sex, income level, health facility type, and avoidable/non-avoidable hospitalizations was performed, and we assessed differences in utilization trends between population groups across three phases of the pandemic.
UNASSIGNED: In early 2020, the COVID-19 pandemic caused a reduction in monthly volume of outpatient utilization by 15.7% [95% CI 13.3%-18.1%, p < 0.001] and inpatient utilization by 11.6% [10.1%-13.0%, p < 0.001]. Most utilization recovered and rebounded to pre-COVID-19 levels as of December 2022 although variations existed. We observed heterogeneity in the magnitude of relative changes in utilization across types of services, varying from a 42.7% [36.8%-48.0%, p < 0.001] decrease for pediatrics, a 23.4% [20.1%-26.5%%, p < 0.001] reduction in utilization of public health centers, and a 24.2% [21.2%-27.0%, p < 0.001] reduction in avoidable hospitalizations compared to the pre-pandemic period. Contrary to global trends, health utilization among the elderly population (65 and older) in South Korea saw only marginal reductions compared to other age groups. Similarly, Medicaid patients and lower income groups experienced a smaller reduction compared to higher income groups.
UNASSIGNED: The impact of the COVID-19 pandemic on healthcare utilization in South Korea was less pronounced compared to the global average. Utilization of vulnerable populations, including adults over 65 years old and lowest-income groups reduced less than other type of patients.

摘要：
■COVID-19大流行大大扰乱了医疗保健利用模式，全球。韩国在遏制疫情蔓延方面受到广泛赞誉,与邻国相比，这可能导致医疗保健利用率的大幅下降。然而,目前尚不清楚COVID-19大流行如何影响人口亚群的使用模式，特别是韩国的脆弱患者群体。本文按分组量化了可归因于COVID-19和COVID-19疫苗接种的医疗保健利用变化。
进行了中断的时间序列分析，以检查2016年1月至2022年12月COVID-19对韩国医疗保健利用的影响，使用国家健康保险系统的汇总患者水平数据，该数据占韩国所有医疗保健服务的99％。我们应用负二项模型来调整季节性和序列相关性。进行证伪测试以测试断点的有效性。按医疗保健服务类型进行分层分析，年龄,性别,收入水平,卫生机构类型,并进行了可避免/不可避免的住院治疗，我们评估了大流行三个阶段人群之间利用趋势的差异.
■2020年初，COVID-19大流行导致每月门诊使用量减少15.7%[95%CI13.3%-18.1%，p<0.001]和住院率11.6%[10.1%-13.0%，p<0.001]。截至2022年12月，大部分利用率恢复并反弹至COVID-19之前的水平，尽管存在差异。我们观察到不同类型服务的利用率相对变化幅度存在异质性，从42.7%[36.8%-48.0%，p<0.001]儿科减少，a23.4%[20.1%-26.5%，p<0.001]公共卫生中心利用率降低，和24.2%[21.2%-27.0%，p<0.001]与大流行前相比，可避免的住院人数减少。与全球趋势相反，与其他年龄组相比,韩国老年人口(65岁及以上)的健康利用率仅略有下降.同样，与高收入群体相比，医疗补助患者和低收入群体的减少幅度较小。
与全球平均水平相比，COVID-19大流行对韩国医疗保健利用的影响不太明显。利用弱势群体，包括65岁以上的成年人和最低收入群体的减少比其他类型的患者少。
■没有资金。
