Objective  To evaluate the performance of new tuberculosis prevention and control service system in Qingyang of Gansu province and provide evidence for the development of tuberculosis prevention and control strategies.

  Methods  The overall successful referral rate of TB/suspected TB patients reported by non-TB prevention institutions, initial hospital visit rate of TB/suspected TB patients, registration rate of active TB patients, pathogenic positive rate of active TB patients, and the success rate of treatment before (2014–2016) and after (2017–2019) the implementation of new tuberculosis prevention and control service system in Qingyang were compared.

  Results  The overall successful referral rate of TB/suspected TB patients was higher during 2017–2019 than that during 2014–2016 (97.60 % vs. 93.11 %, χ²=158.901, P<0.05), the initial hospital visit rate was lower during 2017–2019 than that during 2014–2016 (505.87/100 000 vs. 761.71/100 000, χ²=1309.486, P<0.05), the registration rate of active TB patients was lower during 2017–2019 than that during 2014–2016 (95.32/100 000 vs. 151.55/100 000, χ²=323.159, P<0.05), the pathogenic positive rate of active TB patients was significantly higher during 2017–2019 than that during 2014–2016 (29.60% vs. 13.04%, χ²=258.274, P<0.05), and the success rate of treatment was lower during 2017–2019 than that during 2014–2016 (91.12% vs. 95.29%, χ²=51.029, P<0.05).

  Conclusion  The performance of the new tuberculosis prevention and control service system in Qingyang is well, but the burden of TB patients′ medical care should be alleviated by increasing investment for TB prevention and control. Besides, the coordination among designated hospital, disease control and prevention institution and primary medical and health institutions and the health education department should be strengthened to further improve the quality of TB prevention and control.
