Abstract: Objective: To analyze the application and development of tuberculosis telemedicine consultation and training platform based on internet technology.Methods: A retrospective study was conducted in various activities from the national tuberculosis telemedicine consultation and training platform (remote platform) from March 2012 to December 2021. The activities included training and academic lectures, training courses and academic conferences, case discussion and ward round, case consultation and consultation services, and working meetings. The activity related data were queried and analyzed through the remote platform, including the number of medical institutions covered, the number of various activities, the number of participants in various activities, etc.Results: From 2012 to 2021, the number of units covered by remote platform was increased from 10 to 286, with an average annual growth rate of 45.15%. A total of 1446 remote activities were carried out, and the total number of people participating in remote activities was 1641133. The highest number of activities and participants was in 2020, 459 and 854884, respectively. It had increased by 50 times and 1978 times respectively compared with numbers in 2012 (9 and 432). The activities with the largest cumulative number between 2012 and 2021 were training and academic lectures (617), followed by case consultation and consultation services (568). The activities with the largest number of cumulative participants were training and academic lectures (860093 persons), followed by training courses and academic conferences (699038 persons). The types of activities carried out by remote platform had changed from 2012 to 2021. From the composition ratio of the number of activities carried out, the composition ratio of training and academic lectures decreased the most, from 8/9 in 2012 to 37.98% (128/337) in 2021, while case consultation and consultation increased the most, from 0 in 2012 to 46.29% (156/337) in 2021. In terms of the composition ratio of the number of participants, the composition ratio of training and academic lectures decreased the most, from 89.58% (387/432) in 2012 to 53.92% (331396/614599) in 2021, while training courses and academic conferences increased the most, from 0 in 2012 to 39.68% (243895/614599) in 2021.Conclusion: The tuberculosis telemedicine consultation and training platform based on internet technology had played an important role in the training of tuberculosis diagnosis and control knowledge, the publicity and implementation of policy guidelines, the improvement of primary medical institutions’ capacity, academic exchanges and other aspects, and had great development potentials.
