- W2750611812 abstract "Objective: To evaluate the cost-effectiveness of different screening patterns for active chronic hepatitis C virus (HCV) infections utilizing the hepatitis C core antigen test compared to standard care in the context of a general screening program in a high-prevalence country.Methods: This study developed a decision analytic model to estimate the cost-effectiveness of four screening algorithms for the detection of active HCV infections among asymptomatic individuals with an unknown HCV status in a context of high (>5%) HCV prevalence. Three algorithms started with a serological test for antibodies (AB) followed by a nucleic acid test for HCV-RNA (RNA), the HCVAg (AG) assay, or both. An additional single marker screening strategy with AG was added to the analysis. By the example of the Republic of Georgia, strategies were compared in terms of total costs for screening and diagnosis of an active infection from a health system perspective.Results: Replacing RNA with AG for confirmation of positive AB identified fewer active infections (–110 per 100,000 screened subjects) at significantly reduced total costs (–$2.74 per screened) and costs per diagnosed infection (–$44). Adding a subsequent RNA confirmatory test on AG negative results captured at least the same rate compared to the standard (AB followed by RNA) at still reduced costs (–$1.16 per subject screened, –$22 per case detected). Utilizing AG as the frontline test revealed the highest detection rate (97.9%) at the highest costs (+$3.80 per subject, +$323 per case detected vs standard).Conclusion: A combined pattern of HCV AB screening followed by sequential confirmation with AG and RNA on AG negatives would provide equal or better diagnostic performance at lower cost over a broad range of scenarios. Potential long-term consequences of screening strategies to patients and society have to be considered, since the latency period for HCV to develop into severe liver disease is long." @default.
