- Abstract: Objectives The authors conducted a technical assistance project on tuberculosis (TB) control in Bauleni, Chelston, and Chilenje, Lusaka, Zambia in 2012-2015. Herein we describe the project activities and achievements. Methods We trained community health volunteers (CHVs) and organized their activities. We evaluated the project considering the trends of TB cases, particularly the percent of bacteriologically confirmed TB cases among the presumptive (suspected) TB cases, and treatment outcomes.Results We organized training for the CHVs of three areas. The CHVs conducted a total of 160 community sensitizations attended by over 50 000 community members. They visited their assigned patients 23 716 times. At Bauleni, the number of bacteriologically positive (bac+) cases exhibited a decreasing trend (r = −0.55, p=0.03), whereas that of the presumptive TB cases exhibited an increasing trend (r = 0.70, p = 0.004). At Chelston, both the numbers of bac+ cases and the presumptive TB cases exhibited increasing trends (r = 0.52, p = 0.046 and r = 0.68, p = 0.005, respectively). At Chilenje, the number of bac+ TB cases exhibited a decreasing trend (r = −0.84, p < 0.001), whereas that of the presumptive TB cases did not change (r = 0.09, p = 0.76). In all three areas, the proportions of the bac+ cases among the presumptive TB cases exhibited decreasing trends (p < 0.0001 at all three clinics). The treatment success rates improved in Chelston and Chilenje from 50.7% and 61.9%, respectively, in early 2011 to 78.3% and 97.0%, respectively, in late 2014 (both p < 0.001). The treatment success rates of Bauleni maintained at over 85% in most quarters. Conclusion The activities of the project contributed to the strengthened local national TB programme, resulting in the decreased burden of TB in the areas.
