Abstract:

Objective: To explore the current situation and influencing factors of diagnosis delay among elderly pulmonary tuberculosis (PTB) patients aged 60 and above in Tongzhou District of Beijing, and provide a scientific basis for tuberculosis control strategy in the future. Methods: Medical records of 963 elderly PTB patients in Tongzhou District of Beijing from 2016 to 2022 were extracted from Tuberculosis Management Information System of China Information System for Disease Control and Prevention. Descriptive statistics was used to analyze the distribution and trend of diagnosis delay. Influencing factors of diagnosis delay was analyzed by multivariable logistic regression. Results: From 2016 to 2022, a total of 963 cases of elderly PTB patients aged 60 and above were registered in Tongzhou District of Beijing. The median and quartile of diagnosis delay were 8 (6,17) days. The average annual diagnosis delay rate was 28.45% (274/963). The diagnosis delay rate dropped from 49.68% (78/157) in 2016 to 16.81% (20/119) in 2019, showing a downward trend ( χ t r e n d 2=34.167,P<0.001), and then to 36.62% (52/142) in 2022 showing an upward trend ( χ t r e n d 2=83.199,P<0.001). Multivariable logistic regression analysis showed that cases being actively detected (OR=3.718,95%CI:2.221-6.225) was risk factor for diagnosis delay. The first-diagnosing medical institution being non-Tongzhou District Center for Disease Prevention and Control (OR=0.370,95%CI:0.269-0.510) was protective factor for diagnosis delay. Conclusion: The diagnosis delay of elderly PTB patients increased first, and then decreased in Tongzhou District of Beijing from 2016 to 2022. It was related to the way of case detection and first-diagnosing medical institution. We should implement targeted intervention strategies.
