Background: Tuberculosis (TB) remains a Global Health challenge, with diagnostic delays contributing significantly to its spread. This study investigates the differences in diagnostic delays between native and migrant TB patients in Italy, examining patient-related diagnostic delay (PDD), health system-related diagnostic delay (HDD), and total diagnostic delay (TDD).
Methods: We conducted a retrospective, multicenter, cross-sectional study of TB cases in 10 Italian hospitals from 2018 to 2023.
