Resumen:
This study seeks to analyze the hospital efficiency of the Unified Health System (SUS) in treating COVID-19, between 2020 and 2022. To do this, it uses the Data Envelopment Analysis with Slack (DEA-SBM) and the Malmquist index, with the Brazilian States and the Federal District being the units of analysis. In addition to measuring efficiency, the research examines changes in efficiency, resulting from possible learning in managing the allocation of public resources over time and the different peak phases of the pandemic. The analysis covers both managerial efficiency and clinical efficiency, and the results indicate improvement over time, although persistent challenges, such as significant regional variations, highlight the heterogeneity of disease treatment outcomes
