Board of Experts

World's Best Hospitals - Board of Experts

The global board of medical experts was founded by Statista to support the World's Best Hospitals Project. The board is an independent body that is tasked with the continuous development of the quality and scope of the project.

The board is tasked with providing quality assurance by validating the preliminary hospital rankings, as well as providing input on possible improvements and expansions of the current methodology. This includes input regarding new data sources and improvements to the scoring algorithms as well as the expert's opinion on the best hospitals in specific medical fields.

The members of the board of experts were carefully chosen based on their national and international expertise and decade-long experience in their respective medical fields as well as their scientific output. Current members of the board of experts are listed below.
