[The Korean National Public-Private Mix Tuberculosis Control Project: Analysis of the Indicators for Tuberculosis Management in 2021].

The Korea Disease Control and Prevention Agency has been promoting a "Public-Private Mix Tuberculosis Control Project (PPM Project)" with the "Korean Academy of Tuberculosis and Respiratory Diseases" since 2011. In 2021, 182 PPM institutions participated in the PPM Project, and managed 82.1% of tuberculosis (TB) patients. This study analyzed 35 TB management indicators based on the reported data of TB patients from 182 institutions that participated in the PPM Project in 2021. The final treatment results were confirmed through five-quarter observation by dividing the reported date by quarters. The sputum smear test rate, sputum culture test rate, and sputum MTB PCR test rate reported by PPM institutions in 2021 were 95.9%, 95.6%, and 91.5%, respectively. The rapid drug susceptibility test rate was 87.7% in 2021, an increase from 66.5% in 2020. In 2021, the rates of treatment completion within 12 months, stopped, failure, and still on treatment were 76.5%, 2.3%, 0.06%, and 7.2%, respectively. The mortality rate was 14.0%. In 2021, the household contact investigation rates in adults and children were 92.0% and 93.0%, respectively, down from 94.5% and 94.4% in 2020. On the other hand, the treatment rates for latent TB infection were 74.1% and 95.1% in adults and children, respectively, an increase from the corresponding 69.3% and 91.9% in 2020. The rates of sputum smear tests and sputum culture tests for suspected TB patient among contacts were 47.7% and 42.9%, respectively. Since more than 80% of TB patients are managed by PPM institutions, quality control of PPM institutions is important.
