Abstract
OBJECTIVES: We assessed the effect of an active case finding (ACF) project on tuberculosis (TB) case notification and the yields from a household and neigbourhood intervention (screening contacts of historical index TB patients diagnosed >24months ago) and a community intervention (screening attendants of health education sessions/mobile clinics). DESIGN: Cross-sectional analysis of project records, township TB registers and annual TB reports. RESULTS: In the household and neigbourhood intervention, of 56,709 people screened, 1,076 were presumptive TB and 74 patients were treated for active TB with a screening yield of 0.1% and a yield from presumptive cases of 6.9%. In the community intervention, of 162,881 people screened, 4,497 were presumptive TB and 984 were treated for active TB with a screening yield of 0.6% and yield from presumptive cases of 21.9%. Of active TB cases, 94% were new, 89% were pulmonary, 44% were bacteriologically-confirmed and 5% had HIV. Case notification rates per 100,000 in project townships increased from 142 during baseline (2011-2013) to 148 during intervention (2014-2016) periods. CONCLUSIONS: The yield from household and neigbourhood intervention was lower than community intervention. This finding highlights reconsidering the strategy of screening of contacts from historical index cases. Strategies to reach high-risk groups should be explored for future ACF interventions to increase yield of TB.
