# Health Economics and Outcomes Research

Research discipline that generates economic, clinical, and patient-reported evidence to support payer access, HTA submissions, and value demonstration.

Reviewed by [Christian Espinosa, Founder, Blue Goat Cyber](/authors/christian-espinosa) Last reviewed May 9, 2026 

## Definition

Health Economics and Outcomes Research (HEOR) is the multidisciplinary field that generates economic models (cost-effectiveness, cost-utility, budget impact),  [real-world evidence](/terms/real-world-evidence), and patient-reported outcomes data used by payers,  [HTA](/terms/hta) bodies, and health systems to assess a technology's value. HEOR deliverables include the Global Value Dossier, AMCP Format submissions to US health plans, and country-specific HTA submissions (NICE, CADTH, IQWiG, HAS). 

What the regulation says

Methodology references: ISPOR Good Practices, AMCP Format for Formulary Submissions v4.1, NICE Reference Case,  [ICER](/terms/icer) Value Assessment Framework. CMS's  [TCET](/terms/tcet) program explicitly requires evidence aligned with HEOR principles. 

## What this means in practice

Strong HEOR is the difference between coverage and non-coverage in single-payer systems and is rising in importance for US commercial payers. Increasingly, HEOR planning starts at preclinical/early clinical to ensure trial endpoints support the value story. 

Common pitfalls

-   • Designing pivotal trials around regulatory endpoints only and finding the dataset can't support the HEOR case. 
-   • Treating HEOR as a post-launch activity instead of an evidence-generation strategy from Phase 1.
