Resumo

Objective: This study aimed to evaluate the impact of the COVID-19 pandemic on hospitalization patterns for puerperal
mastitis and breast abscess within the Brazilian Unified Health System (SUS). Methods: An ecological study was conducted using data from the Hospital Information System of the SUS (SIH/DATASUS). Hospitalizations due to postpartum
breast-related issues across Brazil’s five regions were analyzed monthly, with March 2020 set as the interruption point.
Data normality was assessed using a normalized Q-Q plot and a standardized residual histogram in R software, with a
significance level of 5% (p<0.05). Results: A total of 11,279 hospitalizations were analyzed, with incidence rates ranging
from 6 to 10 cases per 10,000 live births between 2018 and 2022. The Central-West region had the highest hospitalization
rates both pre- and post-pandemic, while the Northeast reported the lowest. A 3.35% decline in expected hospitalization
levels was observed after the pandemic in Brazil and in most regions. Conclusion: Hospitalization incidence for postpartum breast conditions varied by period and region. The COVID-19 pandemic contributed to a reduction in incidence
across most Brazilian regions
