Cost-Effectiveness Analysts assess the economic value of medical treatments, devices, and public health interventions by comparing costs and health outcomes. They develop decision-analytic models, perform sensitivity analyses, calculate incremental cost-effectiveness ratios, and interpret quality-adjusted life year metrics. Responsibilities include reviewing clinical evidence, integrating epidemiological data, preparing health technology assessment submissions, and supporting reimbursement decisions. They work in pharmaceutical companies, medical device firms, consulting organizations, government agencies, and research institutions. Global demand is increasing due to rising healthcare costs, reimbursement scrutiny, and widespread adoption of value-based healthcare decision frameworks.
