The objective was to analyze the association of race/skin color in health care, in adults hospitalized with severe acute respiratory syndrome (SARS)/COVID-19, between March 2020 and September 2022, with Brazil as the unit of analysis. This is a cross-sectional study that used the Influenza Epidemiological Surveillance Information System (SIVEP-Gripe) database and had a population composed of adults (≥ 18 years) and the final classification was SARS by COVID-19 or unspecified SARS. The direct effect of skin color on in-hospital mortality was estimated through logistic regression adjusted for age, gender, schooling level, health care system and period, stratified by vaccination status. This same model was also used to assess the effect of skin color on the variables related to access to health care services: intensive care unit (ICU), tomography, chest X-ray and ventilatory support. The results show that black, brown and indigenous people died more, regardless the schooling level and number of comorbidities, with 23%, 32% and 80% higher chances of death, respectively, when submitted to ventilatory support. Racial differences were observed in the use of health care services and in outcomes of death from COVID-19 or unspecified SARS, in which ethnic minorities had higher in-hospital mortality and lower use of hospital resources. These results suggest that black and indigenous populations have severe disadvantages compared to the white population, facing barriers to access health care services in the context of the COVID-19 pandemic.
