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 ten 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., Conclusions: 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., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024.
