Abstract:

Objective: To describe the longitudinal changes of case finding, clinical features and treatment for multidrug-resistant/rifampicin-resistant pulmonary tuberculosis (MDR/RR-PTB) in Nantong City, Jiangsu Province from 2009 to 2020, and to provide scientific guidance for optimizing the prevention and treatment policies for MDR/RR-PTB. Methods: Based on the Tuberculosis Information Management System, we collected the associated data of MDR/RR-PTB patients registered from 2009—2020 in Nantong City, Jiangsu Province. Longitudinal changes of detection rate, demographic characteristics, diagnostic delay, treatment coverage and treatment outcome for MDR/RR-PTB patients were depicted. Results: A total of 426 MDR/RR-PTB patients were detected in Nantong from 2009 to 2020. From 2014 to 2020, 4030 patients were screened, with an overall detection rate of 5.43% (219/4030). The detection rate fluctuated slightly over the years in response to different screening policy, from 16.83% (34/202) in 2014 to 2.85% (32/1123) in 2020, with a significantly decline trend (Ztrend=-11.541, P<0.001). During the past 12 years, the proportion of newly treated MDR/RR-PTB patients increased from 0 in 2009 to 53.12% (17/32) in 2020, and the proportion of patients aged ≥80 years decreased from 53.85% (7/13) in 2009 to 3.12% (1/32) in 2020. Overall, the diagnostic delay showed a decreasing trend since 2009, with the number of 97 (78, 207) days in 2009 and 0 (0, 0) day in 2020. As for treatment outcome among those received standardized treatment, the treatment success rate increased from 60.00% (6/10) in 2009 to 71.88% (23/32) in 2020, and the case fatality rate decreased from 20.00% (2/10) in 2009 to 9.38% (3/32) in 2020. Conclusion: This study showed that the detection rate of MDR/RR-PTB steadily decreased and maintained at a low level, while MDR/RR-PTB patients tended to be younger over time in Nantong City, and the proportion of newly treated patients increased annually. Diagnostic delay of MDR/RR-PTB patients tended to decrease. It is recommended to strengthen the standardized management of treatment in patients, especially for RR-PTB patients, to further decrease transmission.
