With the COVID-19 pandemic, an exacerbation of hospitalizations due to diabetic foot was noted in Brazil, which was due to the loss of access to primary health care by the population, especially the most economically disadvantaged in a country with a vast continental extension and very unequal, economically. We carried out an observational, retrospective and descriptive analysis of hospital data on hospitalization for diabetic foot treatment, using SIH/SUS and DataSUS between 2015 and 2023. Mortality, length of stay, costs, nature of care and demographic distribution of procedures were analyzed. During the period, 196,523 hospitalizations were recorded for the treatment of complicated diabetic foot. In addition, 5,711 cases of deaths were associated with a fatality rate of 0.54%. In relation to financial expenditure, the Northeast Region stood out with the highest expenditure rate. The most socially vulnerable regions had higher hospitalization and mortality rates, although there was little change in financial resources during the pre- and post-pandemic period. This situation highlights the need to promote greater regional equity in indicators and access to health to minimize preventable problems such as UPD. Situations such as the one experienced in the COVID-19 pandemic served to highlight the shortcomings of the country's health system and how the health-disease process is strongly linked to local socioeconomic conditions, making it necessary to promote collective health measures aimed at minimizing disparities regions in Brazilian territory. The lack of data collected by the health event registration system in the country constitutes a limitation in the present study, which makes us suggest greater rigor and diversity in the collection of information in order to better translate the reality of the data presented here.
