Hep C Calculator

Hep C Calculator is an interactive tool developed to evaluate the cost-effectiveness of DAAs for the treatment of HCV globally. The tool utilizes a mathematical model to simulate the life course of HCV-infected populations in 28 countries (considered as priority countries by the World Health Organization). The natural history of HCV calculated using this model has been validated with the results of a multicenter follow-up study of patients with...

Within-Cycle Correction: A Guide for Modelers and Decision Makers

Commonly used decision-analytic models for cost-effectiveness analysis simulate time in discrete steps. Use of discrete-time steps can introduce errors when calculating cumulative outcomes such as costs and quality-adjusted life years. There are a number of myths or misconceptions concerning the need for and how to...
