Health Economics & Outcomes Research

Deliver Evidence

Heightened demands from patients, payers and providers for more information on cost, quality, and outcomes continue to elevate the evidentiary bar. The flood of real world data, clinical trial results, registries, and other data sources creates risks and opportunities as all of this information shapes coverage and treatment decisions, defines value, and impacts patient access. Equipped with a deep understanding of the policy landscape, payer evidentiary demands, and provider behavior, Avalere provides insight on the challenges and opportunities that exist within this space. We combine our broad health economics and outcomes research (HEOR) experience, clinical expertise, payer and provider knowledge, and analytical capabilities to deliver breakthrough evidence generation strategies.
