Abstract
Objective
To analyze the status of patient delay (PD) and diagnosis delay (DD) and explore factors associated with delays among migrant tuberculosis (TB) patients in suburban Shanghai from 2015 to 2024, aiming to provide a scientific basis for targeted TB control strategies.Methods
A retrospective surveillance-based study was conducted using pulmonary tuberculosis (PTB) case data from Fengxian District, Shanghai, obtained from the Tuberculosis Information Management System. Statistical analyses, including the Mann-Whitney U test, chi-square test, multivariable logistic regression, and generalized least squares (GLS) analysis, were performed to examine factors associated with delays. Joinpoint regression was used to analyze temporal trends.Results
A total of 3,178 PTB cases (1,573 locals and 1,605 migrants) were included. Compared with locals, migrants exhibited a significantly shorter median PD (8 vs. 11 days; P Conclusion
Migrants in suburban Shanghai are characterized by a pattern of "shorter PD but prolonged DD." However, the rising trend in PD and the complex effects of cross-district care seeking highlight the urgent need for strengthened inter-district coordination and improved molecular diagnostics at the district level.Clinical trial
