A structured 2-week follow-up visit in the cascade of care for TB increases case detection

• OBJECTIVES: Delayed detection in TB due to structural and diagnostic shortcomings is pivotal for disease transmission, morbidity and mortality. We investigated whether an inclusive screening, followed by a structured clinical follow-up (FU) could improve case -finding. METHODS: Patients were recruited from health centres in Bissau, Guinea-Bissau, and Gondar, Ethiopia. A routine FU was done at Week 2. If persisting symptoms were found, patients were investigated using chest X-ray (CXR) and Xpert (R) MTB/RIF, followed by a medical consultation. The main outcome were additional TB patients diagnosed by applying the FU strategy. RESULTS: Of 3,571 adults, 3,285 (95%) were examined at Week 2 FU, where 2,491 (72%) were asymptomatic. Screening patients presenting with cough > 2 weeks alone contributed to the diagnosis of 93 patients (45% of all patients diagnosed here), whereas a TBscore > 3 increased this by 18 (9%); adding a Week 2 FU yielded an additional 94 (46%) patients. Among the 794 (24%) with persisting symptoms, 25 were diagnosed using Xpert and 69 at clinical FU, which constituted 46% (94/205) of the total TB patients diagnosed. CONCLUSION: A Week 2 FU visit, which can be nested into routine healthcare, increased the diagnosis of TB patients by two -fold and avoids diagnostic gaps in the cascade -of -care.
