To enhance TB case-finding, an Optimized Case Finding (OCF) strategy involving all contacts within the social network of an index TB case was introduced in five regions of Ukraine. We assessed TB detection and linkage to TB treatment using OCF in key populations.</p><p><strong>Methodology:</strong> A cohort study using routine programme data (July 2018 – March 2020). OCF empowers the index TB case to identify and refer up to eight close contacts within his/her social network for TB investigations.</p><p><strong>Results:</strong> Of 726 index TB cases in key populations, 6998 close contacts were referred for TB investigations and 275 were diagnosed with TB (183 drug-sensitive and 92 drug-resistant TB). The TB case detection rate was 3930/100,000 and the Numbers Needed to Investigate to detect one TB case was 25. TB was most frequent among people who inject drugs and homeless groups. Compared to TB detection using routine household case finding within the general population (1090/100,000), OCF was 3.6-fold more effective and when compared to passive case finding in the general population (60/100,000), OCF was 66 times more effective. 99% (273) of TB patients were linked to care and initiated TB treatment.</p><p><strong>Conclusions:</strong> The OCF strategy among key populations is highly effective in detecting TB cases and linking them to care. We advocate to scale-up this case finding strategy in Ukraine and beyond.</p> ER -
