HEOR Specialists combine health economics and outcomes research methodologies to assess clinical and economic value of medicines, devices, and healthcare programs. They develop cost-effectiveness models, conduct budget impact analyses, evaluate real-world evidence, and prepare submissions for health technology assessment bodies. Responsibilities include statistical analysis, literature review, economic modeling, and collaboration with regulatory and market access teams. They work primarily in pharmaceutical companies, medical device firms, consulting organizations, and policy institutions. Global demand is increasing due to rising healthcare costs, reimbursement scrutiny, and expansion of value-based decision frameworks across health systems.
