Primary Health Care and Tuberculosis Detection during the COVID-19 Pandemic: Crucial Actions for Intensifying Efforts

Background: Tuberculosis has been considered a global emergency since 1993, and controlling it has become even more challenging since 2020 due to the health and social crisis resulting from the COVID-19 pandemic. This study aimed to identify the impact of the COVID-19 pandemic on tuberculosis case detection activities within primary health Care in the largest city in Brazil. Methods: This is a cross-sectional and analytical study on the provision of tuberculosis detection actions in primary healthcare units during the pandemic period. A descriptive analysis was performed for characterization, and Generalized Mixed Models were used for evaluating associations, with a Bonferroni post hoc test applied. Results: The study sample comprised 80 health units in the municipality. There was a moderate alteration level in the provision of consultations for individuals with signs and symptoms of tuberculosis in 2020 (13.8%) and in 2021 (15.1%). Statistical significance (p < 0.05) was found between the pandemic period and detection actions, with a lower alteration level in 2022. Conclusions: Tuberculosis detection activities underwent changes due to the COVID-19 pandemic, mainly in 2020, which was associated with alterations in consultation and case notification provision.
