One of the main responsibilities of health systems impacted by the global Coronavirus disease 2019 (COVID-19) pandemic, where the first case was discovered in Wuhan, China, in December 2019, is the provision of medical services. The current study looked into the impact of vaccination on the utilization of services provided to COVID-19 patients.
This study was conducted in Iran between 2021 and 2022, utilizing a cross-sectional research design. The research team collected data on the utilization of provided services and the number of COVID-19 vaccines administered to 1000 patients in Iran through a random sampling approach. The data were analyzed with statistical methods, including the mean difference test, and multiple linear regression.
Regression estimates show that after controlling for confounding variables like age, type of admission, and comorbidities, vaccination reduces the utilization of healthcare services in the general majority of services. The study's results reveal a fall in COVID-19 patients' utilization of services, specifically in patients administered two or three doses of the vaccine. However, the reduction is not statistically significant. Regression models are in contrast to univariate analysis findings that vaccination increases the mean utilization of healthcare services for COVID-19 patients in general. Comorbidities are a crucial factor in determining the utilization of diagnostic and treatment services for COVID-19 patients.
Full COVID-19 vaccination and other implementations, including investing in public health, cooperating globally, and vaccinating high-risk groups for future pandemics, are essential as a critical response to this pandemic as they reduce healthcare service utilization to alleviate the burden on healthcare systems and allocate resources more efficiently.
受2019年全球冠状病毒病（COVID-19）大流行影响的卫生系统的主要职责之一是提供医疗服务，该疾病于2019年12月在中国武汉发现首例病例。本研究探讨了疫苗接种对为COVID-19患者提供的服务利用情况的影响。
本研究于2021年至2022年在伊朗进行，采用横断面研究设计。研究团队通过随机抽样方法收集了伊朗1000名患者的服务利用情况数据以及接种的COVID-19疫苗数量。数据采用包括均值差异检验和多元线性回归在内的统计方法进行分析。
回归估计显示，在控制年龄、入院类型和合并症等混杂变量后，疫苗接种在大多数服务中降低了医疗服务的利用率。研究结果显示COVID-19患者的服务利用率下降，特别是在接种两剂或三剂疫苗的患者中。然而，这种下降在统计学上并不显著。回归模型与单变量分析结果相反，单变量分析结果表明总体上疫苗接种会增加COVID-19患者医疗服务的平均利用率。合并症是决定COVID-19患者诊断和治疗服务利用率的关键因素。
全面接种COVID-19疫苗以及其他举措，包括投资公共卫生、全球合作以及为未来大流行对高危人群进行疫苗接种，作为对这一流行病的关键应对措施至关重要,因为它们可以降低医疗服务利用率，减轻卫生系统负担并更有效地分配资源。
