Abstract

BACKGROUND:

implementing one-step strategies for hepatitis C diagnosis would help shorten the time to treatment access. Thus avoiding disease progression and complications, while facilitating hepatitis C virus (HCV) elimination.

OBJECTIVE:

to assess the validity and safety of potential one-step strategies for the diagnosis of HCV infection and their associated cost and efficiency.

METHODS:

the study design is an economic appraisal of efficiency (cost/efficacy) using decision trees and deterministic sensitivity analysis. The analysis was performed from the payer perspective (Spanish National Health System), which exclusively considers the direct costs. Only the differential costs (diagnostic testing costs) were taken into account and the study was set in Spain. The efficacy of a diagnostic strategy was defined as the percentage of patients with an active HCV infection who received a positive diagnosis and the efficiency was defined as the cost per patient with a correctly diagnosed and active infection.

RESULTS:

the one-step strategies evaluated for the diagnosis of HCV had an acceptable validity and safety due to the high sensitivity and specificity of the considered tests. The Ab-Ag strategy was the most efficient, followed by Ab-Ag-VL and Ab-VL. Ab-Ag was the most efficient due to the lower cost per patient tested, although the efficacy was lower than the Ab-VL efficacy.

CONCLUSION:

the study findings may help to establish more appropriate one-step diagnostic approaches whilst considering the efficacy and efficiency.
