Background:
Tuberculosis Building and Strengthening Infection Control Strategies (TB BASICS) aimed to achieve improvements in TB infection prevention and control (IPC) through structured training and mentorship.
Methods:
TB BASICS was implemented in 6 Chinese provinces from 2017 to 2019. Standardized, facility-based risk assessments tailored to inpatient, laboratory, and outpatient departments were conducted quarterly for 18months. Knowledge, attitudes, and practices surveys were administered to health care workers (HCW) at 9 participating facilities during the first and last assessments. Kruskal-Wallis rank sum test assessed score differences between departments (alpha=0.05).
Results:
Fifty-seven departments received risk assessments. IPC policies and practices improved substantially during follow up. Facility-based assessment scores were significantly lower in outpatient departments than other departments (P<.05). All indicators achieved at least partial implementation by the final assessment. Low scores persisted for implementing isolation protocols, while personal protective equipment use among staff was consistent among all departments. Overall, we observed minimal change in IPC knowledge among HCW. In general, HCW had favorable views of their own IPC capabilities, but reported limited agency to improve institutional IPC.
Conclusions:
TB BASICS demonstrated improvements in TB IPC implementation. Structured training and mentorship engaged HCW to maintain confidence and competency for TB prevention.

The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
