ABSTRACT
BACKGROUND: In Russia, mass chest X-ray (CXR) screening for tuberculosis (TB) is mandatory.OBJECTIVE: To compare the yield and the cost per TB case detected and the total cost of CXR screening, passive case finding and contact tracing among adolescents and adults in the Arkhangelsk Oblast, Russian Federation, 2013-2017.DESIGN: This was an analysis of costing strategies using aggregated data. Costing information was obtained from the Finance Department of the Arkhangelsk Clinical TB Dispensary, Arkhangelsk, and the Territorial Fund of Mandatory Medical Insurance, Arkhangelsk, Russian Federation.RESULTS: TB cases were detected using CXR screening (n = 684, 46%), contact tracing (n = 61, 4%) and passive case finding (n = 743, 46%). The number of cases detected using CXR screening, contact tracing and passive case finding was respectively 28,753 and 960/100 000. The mean costs/test were respectively US$3.54 (US$12 541/case), US$20.28 (US$2693/case) and US$11.85 (US$1235/case) using CXR screening, contact tracing and passive case finding The number of cases/100 000 in targeted groups was as follows: HIV-positive persons, 645; homeless persons, 461; and migrants, 441. The cost/TB case detected was respectively US$549, US$768 and US$803.CONCLUSION: Mass CXR screening (excluding HIV-positive, migrant and homeless populations) has low yield and high cost per TB case detected. It should be stopped and resources should instead be used to strengthen the screening of targeted high-risk groups, contacts and passive case finding.
