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. We compared PDD, HDD, and TDD between native and migrant populations. Socio-demographic data and clinical histories were analyzed to identify factors contributing to diagnostic delays. Results: We included 669 TB patients (390 migrants and 279 natives). Migrants experienced significantly longer PDD (median 90 vs 10 days, P < 0.0001) but shorter HDD (median 5 vs 40 days, P < 0.0001) compared to natives, resulting in a longer TDD (median 96 vs 65 days, P < 0.0001). Furthermore, migrants had higher Timika scores, longer sputum conversion times, and were more frequently lost to follow-up. Conclusion: Migrants face longer PDD, emphasizing substantial barriers to healthcare access. Natives experience longer HDD, reflecting neglect of TB in low-endemic regions. Future research should focus on the impact of social determinants and training for healthcare providers on TB diagnosis and develop strategies to reduce diagnostic delays.
