Inequality in Health Care Utilization by Income Level Before and During the Early Stage of the COVID-19 Pandemic

Abstract

Income inequality has worsened since the COVID-19 pandemic. As public hospitals have been converted to a dedicated system for infectious diseases, it has become more difficult for low-income people to access medical care. This study aims to analyze the inequality in medical care utilization according to income after the COVID-19 epidemic. The survey data was from the 15th and 16th waves of the Korea Welfare Panel, and the analysis methods of concentrated index (CI) and Le Grand index were used to analyze inequality in medical care utilization according to income before and after the COVID-19 pandemic. Our analysis found that the number of outpatient and inpatient utilizations and medical expenses were higher for the middle and high-income levels compared to the low-income level during the COVID-19 pandemic. Before and during the COVID-19 epidemic, it was found that poor subjective health and disability were concentrated at the low-income level. However, when outpatient and inpatient utilization, which was concentrated at lower income levels, reflected the health status, it was found to be advantageous for individuals with higher income levels. Before and during the pandemic, health status was reflected in medical expenses, and medical care utilization was advantageous to those with higher income levels. During the COVID-19 pandemic, inequality in medical care utilization by income level worsened. Therefore, in times such as the COVID-19 pandemic, additional policies are needed to serve as a medical safety net and to prevent restrictions on medical care utilization, especially for low-income individuals.
