Abstract:
Objective:To analyze the treatment outcome and its related factors of rifampicin-resistant pulmonary tuberculosis (RR-PTB) patients in Shaanxi Province from 2017 to 2022.Methods:Through the "Drug-resistant Cases" in the "Surveillance Report Management" subsystem of the "China Disease Control and Prevention System", the RR-PTB patients registered from January 1st, 2017 to December 31st, 2022 in Shaanxi Province were collected.A cross-sectional study was used to analyze the epidemiological characteristics, history of anti-tuberculosis treatment, medication status, and treatment outcomes and prognosis of the patients was performed. The trend analysis was conducted by trend chi-square test. Chi-square test was used for statistical comparison. Multivariable logistic regression model was used to analyze factors influencing the treatment outcome of RR-PTB patients.Results:From 2017 to 2022, a total of 2 582 cases of RR-PTB were registered in Shaanxi Province. Epidemiological characteristics showed that the male registration incidence (1.55/100 000) was higher than that of females (0.61/100 000), and the difference was statistically significant ( χ2=473.04, P<0.001). The population was mainly young and middle-aged (38.88%(1 004/2 582)) and farmers (66.50%(1 717/2 582)). The highest registered incidence was in Southern Shaanxi (1.71/100 000). A total of 1 567 cases were successfully treated, with a successful treatment rate of 60.69%. The successful treatment rate of RR-PTB patients increased from 58.17%(121/208) in 2017 to 66.41%(174/262) in 2022, which showed an overall upward trend with statistically significant (trend χ2=62.84, P<0.001). The multivariable logistic regression analysis showed that male (odds ratio ( OR)=1.838, 95% confidence interval ( CI) 1.392 to 2.427, P<0.001), 45 to 64 years old ( OR=2.119, 95% CI 1.361 to 3.300, P=0.001), ≥65 years old ( OR=5.070, 95% CI 3.016 to 8.521, P<0.001), living the Northern Shaanxi ( OR=1.639, 95% CI 1.087 to 2.471, P=0.018), retreatment ( OR=1.646, 95% CI 1.264 to 2.144, P<0.001), with cross-regional mobility ( OR=1.821, 95% CI 1.403 to 2.363, P<0.001), cumulative months of medication <6 months ( OR=55.310, 95% CI 40.267 to 75.974, P<0.001), family member or self-medication management ( OR=2.176, 95% CI 1.527 to 3.100, P<0.001) were risk factors for successful treatment of RR-PTB patients. Conclusions:The successful treatment rate of RR-PTB patients in Shaanxi Province has shown an upward trend.Male, age ≥45 years, living in the Northern Shaanxi, retreatment, cross-regional mobility, cumulative months of medication <6 months, family or self-medication management are risk factors for treatment outcome of RR-PTB patients.Treatment management, the supervision and propaganda education should be strengthened to further reduce the risk of adverse treatment outcomes.
