Located in Ha Noi, the National Institute of Tuberculosis and Lung Diseasesis responsible for the direction and management of TB control activities at the central level. The institute supports the MOH in developing TB- related strategies, and in handling management and professional guidelines for the system. The provincial level centers diagnose, treat, and manage patients, implement TB policies issued by the NTP, and develop action plans under the guidelines of the Provincial Health Bureau and the provincial TB control committees. The districts are capable of detecting TB and treating patients. All districts have physicians specializing in TB, laboratories, and X-ray equipment and have either a TB department or a TB-communicable diseases department in the district hospital. The district level is also responsible for implementing and monitoring the NTP, and the supervision and management of TB programs in the communes. The commune level provides treatment as prescribed by the district level, administering drugs, and vaccinating children. In TB control, village health workers play critically important roles in identifying suspected TB patients, conducting counseling for examination and tests, paying home visits to patients undergoing treatment, and reporting problems in monthly meetings with the CHC.
