Objective  To evaluate pulmonary tuberculosis (TB) distribution and reporting in different types of medical and health institutions in Beijing, and provide evidence for standardizing TB diagnosis and reporting in medical institutions.

  Methods  The information of pulmonary TB cases in Beijing in 2019 was collected via national Tuberculosis Information Management System (TBIMS) and analyzed by descriptive epidemiology method.

  Results  In 2019, a total of 25 566 pulmonary TB cases were reported by 336 medical and health institutions in Beijing, of which 11 301 were confirmed pulmonary TB cases, accounting for 44.20%. A total of 12 151 pulmonary TB cases were reported by 21 designated medical institutions, accounting for 47.53%, and 13 415 pulmonary TB cases were reported by 315 non-designated medical institutions, accounting for 52.47%. Among the designated medical institutions, Beijing Chest Hospital reported the most pulmonary TB report cases (9 228 cases, 36.09%). Among the non-designated medical institutions, the Eighth Medical Center of PLA General Hospital reported the most pulmonary TB cases (1 402 cases, 5.48%). A total of 15 721 pulmonary TB cases were local residents in Beijing (61.49%) and 9 845 cases were not local residents in Beijing (38.51%). The pulmonary TB cases in local residents were mainly reported by general hospitals (7 737 cases, 49.21%), and the pulmonary TB cases in non-local residents were mainly reported by special hospitals (5 163 cases, 52.44%). The pulmonary TB cases in non-local residents were mainly from the surrounding provinces of Beijing, such as Hebei (3 703 cases, 37.61%). The proportions of confirmed pulmonary TB cases in designated and non-designated medical institutions were 58.76% and 31.02% respectively. The difference was significant (χ²=1 989.69, P<0.001). The proportions of the pulmonary TB cases in local residents and non-local residents under registration management were 71.43% and 53.49%, respectively. The difference was significant (χ²=368.64, P<0.001). There were also differences in the proportion of pulmonary TB cases in local residents under registration management among different districts (counties) in Beijing, which was highest in Mentougou district (94.16%) and lowest in Chaoyang district (40.29%).

  Conclusion  More pulmonary TB patients visited non-designated medical institutions, but the proportion of confirmed pulmonary TB cases reported by them was lower than that reported by designated medical institutions. The reported pulmonary TB cases were mainly local residents in Beijing, and the pulmonary TB cases in non-local residents were mainly from Hebei. The registration management rate was higher in pulmonary TB cases in local residents than in pulmonary TB cases in non-local residents, and there were also differences in the registration management rate in pulmonary TB cases in local residents among different districts (counties) in Beijing.
