OBJECTIVES: Extrapulmonary tuberculosis (EPTB) is not a notifiable infectious disease in China but is a heavy burden on public health. However, the epidemic situation of EPTB nationwide is unclear. This study aimed to investigate the magnitude and main subtypes of EPTB in China.
METHODS: We conducted a national cross-sectional study with multistage, stratified cluster random sampling during 2020-2021. We calculated proportions of EPTB in all patients with TB by organs. Logistic regression models were used to estimate odds ratios by characteristics.
RESULTS: A total of 6843 patients with TB were included. Of them, 24.6% were patients with EPTB, and the proportion of EPTB solo was 21.3%. Higher EPTB burden was observed in children, female patients, clinically diagnosed patients, provincial-level and prefectural-level health facilities, and Central and West China. EPTB occurred most frequently in respiratory (35.5%), musculoskeletal (15.8%), and peripheral lymphatic (15.8%) systems with top three subtypes, including tuberculous pleurisy (35.0%), spinal TB (9.8%) and cervical tuberculous lymphadenopathy (7.9%). With the increase of age, proportion of peripheral lymphatic TB decreased, and proportion rank of genitourinary TB rose.
CONCLUSION: It is essential to strengthen the diagnosis and treatment capacity for EPTB in primary medical facilities. EPTB should be added to the National Tuberculosis Program as a notifiable disease.
