RESUMEN
OBJECTIVES: To assess the yield and cost of implementing systematic screening for tuberculosis (TB) disease among people living with HIV (PLHIV) and initiation of TB preventive treatment (TPT) in Ghana. DESIGN: Prospective cohort study from August 2019 to December 2020. SETTING: One hospital from each of Ghana's regions (10 total). PARTICIPANTS: Any PLHIV already receiving or newly initiating antiretroviral treatment were eligible for inclusion. INTERVENTIONS: All participants received TB symptom screening and chest radiography. Those with symptoms and/or an abnormal chest X-ray provided a sputum sample for microbiological testing. All without TB disease were offered TPT. PRIMARY AND SECONDARY OUTCOME MEASURES: We estimated the proportion diagnosed with TB disease and proportion initiating TPT. We used logistic regression to identify factors associated with TB disease diagnosis. We used microcosting to estimate the health system cost per person screened (2020 US$). RESULTS: Of 12 916 PLHIV attending participating clinics, 2639 (20%) were enrolled in the study and screened for TB disease. Overall, 341/2639 (12.9%, 95% CI 11.7% to 14.3%) had TB symptoms and/or an abnormal chest X-ray; 50/2639 (1.9%; 95% CI 1.4% to 2.5%) were diagnosed with TB disease, 20% of which was subclinical. In multivariable analysis, only those newly initiating antiretroviral treatment were at increased odds of TB disease (adjusted OR 4.1, 95% CI 2.0 to 8.2). Among 2589 participants without TB, 2581/2589 (99.7%) initiated TPT. Overall, the average cost per person screened during the study was US$57.32. CONCLUSION: In Ghana, systematic TB disease screening among PLHIV was of high yield and modest cost when combined with TPT. Our findings support WHO recommendations for routine TB disease screening among PLHIV.
