The COVID-19 pandemic began at the end of 2019 and quickly spread over the planet. It began in Jakarta, Indonesia, in the beginning of March 2020. Jakarta saw the greatest number of confirmed cases during the initial pandemic year due to its dense population. This has sparked worries about the responsiveness of the city's healthcare systems and accessibility to healthcare, which is crucial for regulating the dynamics of illness and death. To address the need for hospital beds, a number of hospitals in Jakarta have been designated COVID-19 healthcare centers. Studies on healthcare accessibility are generally accessible, however there is a dearth of studies examining the effects of healthcare accessibility given the severity of the COVID-19 epidemic. In the first year of the COVID-19 pandemic, this study intends to analyze the spatiotemporal dynamics of healthcare accessibility in relation to COVID-19 cases and its impact on case fatality rate (CFR). In order to compare the accessibility of COVID-19 healthcare with the monthly statistics of the COVID-19 infected population, two stages floating catchment area was adopted. Following these investigations, the accessibility scores are analyzed using Product Moment Pearson correlation with the CFR to look at the relationship. This study's findings indicate that there is only a weak negative link between healthcare accessibility and CFR, which is not statistically significant. © The Authors, published by EDP Sciences.
