Abstract:

Objective: To investigate the situation of diagnostic delay among pulmonary tuberculosis (PTB) patients in Haidian District from 2015 to 2024 and analyze the influencing factors, to provide evidences for tuberculosis prevention and control strategies in Haidian District. Methods: The data of PTB patients with current residential address in Haidian District reported from 2015 to 2024 were exported from the case management module in the Surveillance Report Management System of the China Information System for Disease Prevention and Control. The influencing factors of diagnostic delay were analyzed by using the χ2 test, Kaplan-Meier method, log-rank test, and multivariate logistic regression. Results: A total of 7769 PTB patients with current residence in Haidian District were reported from 2015 to 2024. The median diagnostic delay was 20 (6, 45) d, which decreased from 20 d in 2015 to 18 d in 2024. There were 3085 patients with diagnostic delay, with the rate of 39.71% (3085/7769). The delay rate decreased from 40.80% in 2015 to 36.50% in 2024 (${\chi }_{trend}^{2}$=23.518, P<0.01). Compared with workers, household duties/unemployed individuals (OR=1.322,95%CI:1.072-1.629) had a higher risk of diagnostic delay. Compared with patients without bacteriological results, bacteriologically negative (OR=1.192,95%CI:1.056-1.346) was risk factor for diagnostic delay. Compared with the period 2015—2017, patients diagnosed during the period 2021—2024 had a lower risk of delay (OR=0.783,95%CI:0.697-0.878). Conclusion: The diagnostic delay among PTB patients in Haidian District showed a decreasing trend from 2015 to 2024. Bacteriologically negative, household duties/unemployment were identified as the main risk factors for diagnostic delay.
