What Is HEOR?

Interest in the field of health economics and outcomes research (HEOR) has grown exponentially as governments and other payers grapple with how to provide the best possible health outcomes at affordable costs. At ISPOR, we believe that every healthcare decision should be informed by the best scientific research derived from rigorous, proven methodologies. Toward that goal, the Society’s mission is to promote HEOR excellence to improve decision making for health globally.


In today's world, healthcare decision makers across the globe are often faced with the need to select therapeutic "interventions" from multiple treatment options, including biopharmaceuticals, medical devices, and healthcare services. However, the benefits and costs of these interventions can range dramatically and the benefits can be economic, clinical, both, or may include hard to measure costs or benefits the patient experiences directly. Health economics and outcomes research (HEOR) can help healthcare decision makers—including clinicians, governments, payers, health ministries, patients, and more—to adequately compare and choose among the available options.
