Abstract

For the 20th anniversary issue of Value in Health, we wanted to reflect on how “value” has been defined, measured, and debated since the journal started. At the same time, Value in Health continues to be forward-looking. We are grateful to the 2 former Editors-in-Chief, Joel W. Hay, PhD, and Josephine Mauskopf, PhD, MHA, for setting the trajectory for excellence in peer review, and we are proud of the impact that Value in Health has made on the field of health economics and outcomes research (HEOR) as we celebrate the journal's achievements over the past 20 years.

In planning this special anniversary issue, we issued a call for papers to attract submissions on value-related topics that have been widely discussed in Value in Health over the past 2 decades and for which there remain current debate and an exciting future agenda. More than 60 articles were submitted for this 20th anniversary issue, and we selected 17 articles on the basis of our peer-review process. The selected articles discuss various topics, which we have categorized under 3 main themes: Notions of “Value” in Healthcare, Decision-Analytic Modeling, and HEOR in the Broader Context of Health Technology Assessment (HTA) and Comparative-Effectiveness Research.
