To mark NAO’s newest Health Systems in Transition (HiT) publication, the authors and founding director Greg Marchildon gave a public virtual presentation at the Seminario Institucional in Mexico City. The new volume on Mexico completes the North American trilogy, accompanying Canada (3rd ed) and the USA (2nd ed). Dr. Marchildon discussed the project’s origins in the European Observatory on Health Systems and Policies HiT series, which relies on a rigorous template to define and structure the information to allow for insightful comparison across jurisdictions. The aim of these studies is to both document and conceptualize the various national and subnational components of a country’s health system, as well as to facilitate in-depth assessments of their governance, accessibility, financing, quality, outcomes, and efficiency. Dr. Marchildon expressed gratitude for the years of effort and leadership from NAO Associate Director (Mexico) Dr. Miguel Á. González Block and his co-authors, Hortensia Reyes Morales, Lucero Cahuana Hurtado, Alejandra Balandrán, and Edna Méndez.
