Abstract:
Abstract: Objective To analyze the epidemic characteristics of etiologically positive pulmonary tuberculosis, and the outcome of treatment in Liaoning Province from 2016 to 2022, aiming to provide a scientific basis for the formulation of tuberculosis prevention and control measures in Liaoning Province. Methods The medical records information of registered pulmonary tuberculosis patients in Liaoning Province from 2016 to 2022 was collected from the "Tuberculosis Information Management System", a subsystem of the "China Disease Prevention and Control Information System". A descriptive analysis was performed on the epidemiological characteristics and treatment outcomes of cases of pathogen-positive pulmonary tuberculosis. Results From 2016 to 2022, a total of 152 778 cases of active pulmonary tuberculosis were registered in Liaoning Province. Registration rates decreased from 54.48/100 000 in 2016 to 39.12/100 000 in 2022, displaying a downward trend (χ2trend=1 921.17, P<0.001). The etiological positive rate increased from 26.70% in 2016 to 51.21% in 2022, indicating an upward trend (χ2trend=5 203.00, P<0.001). The etiological positive registration rate increased from 14.54/100 000 in 2016 to 20.03/100 000 in 2022, showing an upward trend (χ2trend=647.97, P<0.001). The male-female ratio of etiological positive was 3.35∶1. The age group of 55-<65 had the highest incidence rate at 25.45% (16 127/63 376) among pathogen-positive pulmonary tuberculosis cases. Patients over 45 years of age accounted for 71.27% (41 570/63 376) of total cases, pointing towards an aging trend. The main occupations of the patients were household and unemployed, making up 41.78% (26 477/63 376) of total cases and showed an increasing year-on-year trend (χ2trend=17.404, P<0.001). Direct medical consultation was the primary mode of patient source at 50.28%(31 864/63 376), while 64.54%(40 904/63 376) cases reported a delay in seeking treatment. Seasonality was observed in the occurrence of pathogen-positive pulmonary tuberculosis, with February and September being the months of lowest incidence, while May and June witnessed peak incidences. The etiological positive patients were mainly in Shenyang, Dalian, Jinzhou and other regions. The proportion of successful treatment of etiologically positive decreased from 91.15% in 2016 to 85.88% in 2022, manifesting a downward trend (χ2trend=35.892, P<0.001). Conclusions From 2016 to 2022, the incidence and registration rates of pathogen-positive pulmonary tuberculosis in Liaoning Province displayed an upward trend. Several characteristics were observed including seasonal variations, delayed treatment, regional distribution differences, and a decline in successful treatment rates. Targeted prevention and control measures should be formulated according to the actual situation in Liaoning Province.
