Supplementary tables: Impact of the COVID-19 pandemic on healthcare resource utilization across selected disease areas in the USA

These are peer-reviewed supplementary materials for the article 'Impact of the COVID-19 pandemic on healthcare resource utilization across selected disease areas in the USA' published in the Journal of Comparative Effectiveness Research.Supplementary Table 1: Pharmaceutical disease cohorts' characteristicsSupplementary Table 2: Oncology disease cohorts' characteristicsSupplementary Table 3: Disease areas and ICD-10 clinical modification diagnosis codesSupplementary Table 4: Total pre-pandemic and pandemic outpatient visits and the percentage change in outpatient visits for each disease areaSupplementary Table 5: Total pre-pandemic and pandemic inpatient visits and the percentage change in inpatient visits for each disease areaSupplementary Table 6: Total pre-pandemic and pandemic ED visits and the percentage change in ED visits for each disease areaAim: To analyze the impact of the COVID-19 pandemic on US healthcare resource utilization. Methods: Optum claims data were used to compare all-cause healthcare visits and healthcare spending for selected diseases between the prepandemic and pandemic periods. Telemedicine use was only assessed for the pandemic period owing to data availability. Results: During the first wave of the pandemic, all-cause healthcare visits across all selected disease areas displayed a rapid decline compared with the prepandemic period, followed by a period of recovery. A reduction in outpatient and home healthcare spending was observed, whereas inpatient and prescription spending increased. Conclusion: Changes in healthcare resource utilization trends were observed during the pandemic. The magnitude of these changes can inform subsequent studies that utilize COVID-19-era data.

本数据集为发表于《比较有效性研究杂志》的论文《COVID-19大流行对美国选定疾病领域医疗资源利用的影响》的同行评审补充材料。补充表格1：药物疾病队列特征；补充表格2：肿瘤疾病队列特征；补充表格3：疾病领域及ICD-10临床修改诊断代码；补充表格4：大流行前和大流行期间的总门诊就诊次数及各疾病领域的门诊就诊次数百分比变化；补充表格5：大流行前和大流行期间的总住院就诊次数及各疾病领域的住院就诊次数百分比变化；补充表格6：大流行前和大流行期间的总急诊就诊次数及各疾病领域的急诊就诊次数百分比变化。研究目的：分析COVID-19大流行对美国医疗资源利用的影响。研究方法：利用Optum索赔数据，比较大流行前和大流行期间选定疾病的全部原因医疗就诊和医疗支出。由于数据可用性，仅评估了大流行期间的远程医疗使用。研究结果：在大流行第一波期间，与大流行前相比，所有选定疾病领域的全部原因医疗就诊均出现迅速下降，随后进入恢复期。观察到门诊和居家医疗支出减少，而住院和处方支出增加。研究结论：在大流行期间，医疗资源利用趋势发生了变化。这些变化的幅度可以为利用COVID-19时代数据的后续研究提供信息。
