From: Impact of community tracer teams on treatment outcomes among tuberculosis patients in South Africa
Overview of the TB Tracer Project implementation and study population of TB patients registered in the ETR included for analysis (n = 405,673). The South African National TB Program selected 2 to 4 districts from each of the 9 provinces of South Africa for inclusion in the TB Tracer Project. The selected districts were those with the highest rates of treatment default in 2006. The districts then selected four to six subdistricts to carry out the project with at least one tracer team assigned to each selected subdistrict.
