Abstract:
Objective To understand the current status of delays in the case-finding, treatment and diagnosis of tuberculosis (TB) and related factors in students in Ningbo, Zhejiang province, from 2010 to 2022, and provide reference for reducing the delay in TB detection in students.
Methods The incidence data of TB in students in Ningbo from 2010 to 2022 were collected through National Tuberculosis Information System to analyze the basic characteristics and change trends of delays in the detection, treatment and diagnosis of of TB in students, and χ2 test and multivariate logistic regression analyses were used to analyse influencing factors.
Results A total of 2055 TB cases were reported in students in Ningbo during this period, and the median intervals of TB detection, treatment and diagnosis delays of TB cases were 20 d, 12 d, 4 d, and the delay rates of TB detection, treatment and diagnosis were 38.88%, 45.45%, 14.50%, respectively. Being floating population, onset in spring and winter , being etiological positive and passive detection such as hospital visit, referral, and follow up were the main risk factors for the delay in TB detection in students.
Conclusion The delay of TB case finding in students in Ningbo was slightly higher than the average level of Zhejiang, Passive discovery was a risk factor for the case finding delay, and the active screening of new students might reduce the delay of medical treatment, and active screening strategies for new student enrollment should be fully promoted.
