RESUMEN
Objective To study patient delay and the influencing factors of the elderly patients with pulmonary tuberculosis（PTB），so as to provide evidence for developing effective prevention and control strategies. Methods Derived the information from PTB management information system in 2010-2019 of the tuberculosis patients who were aged 60 years or older in Huai'an City, described and analyzed the influencing factors of patient delay. Results The median time of PTB patients delay in Huaian was 21 day, while the rate was 65.91%. Multivariate logistic regression analysis results showed that compared with permanent residents, city dwellers, the first diagnosis unit specialized hospital, and the patient source referral, the patient delay risks of the floating residents（OR = 2.942 , 95% CI: 2.461-3.518）, the country dwellers（OR = 1.528,95% CI :1.377-1.697）, the first diagnosis unit general hospital（OR = 1.203,95% CI: 1.087-1.333）, and the patient source recommendation （OR = 2.395,95% CI: 1.960-2.928）were higher, Compared with the peasants（OR = 0.315 , 95% CI : 0.213-0.512）, new patients（OR = 0.812 , 95% CI : 0.689-0.974） and sputum smear positive patients（OR = 0.866 , 95% CI : 0.780-0.962）, the patient delay risks of the non-peasants, recurrent patients, and sputum negative patients were lower. Conclusion The patient delay of the elderly patients with pulmonary tuberculosis（PTB）in Huaian was serious, the influencing factors of patient delay were type of household registration, current residence, occupation, type of first-time unit, source of patient , classification of treatment, and the sputum test results.
