Best Specialized Hospitals 2022 - Endocrinology

World's Best Specialized Hospitals 2022

As part of Newsweek's long standing commitment to cover all aspects of health, we've again partnered with global research firm Statista to rank the world's best specialized hospitals.

Last year, we looked at the best facilities in six specialities: cardiology, oncology, endocrinology, neurology, gastroenterology and orthopedics. This year we are proud to expand that to ten specialities. The ranking features the top 250 hospitals for cardiology and oncology, the top 150 for cardiac surgery and pediatrics and the top 125 each in endocrinology, gastroenterology, orthopedics, neurology, neurosurgery and pulmonology.

If you or a loved one needs specialized care in one of those areas, you'll want to know which hospitals or state of the art facilities have the most accomplished physicians and diagnosticians and offer the highest level of care. We hope that you will find our ranking helpful.

The 2022 World's Best Specialized Hospitals is based on a global survey of medical professionals. The recommendation score is based on two sub-scores, for primary recommendations and secondary recommendations. In cooperation with Newsweek, Statista invited over 40,000 medical experts (medical doctors, healthcare professionals, hospital managers and directors) in over 20 countries to an online survey. Additionally, experts from all over the world were able to participate in the "World's Best Specialized Hospitals 2022" survey on The data were collected from June to August 2021.

Participants were asked to recommend and rank hospitals based on their expertise in one primary medical field (e.g. cardiology for cardiologists) and were able to choose an optional secondary area of expertise. Secondary recommendations were given a lower weight. The questionnaire did not suggest a list of hospitals and respondents were free to suggest any hospital they deemed recommendable (aided by an autocomplete function for convenience). Statista performed plausibility checks on all data to prevent self-nomination.

A preliminary reputation score was calculated for every hospital based on the weighted recommendations in each medical field. The preliminary reputation score was used to generate the preliminary lists for the ten medical fields. Hospitals that specialize in more than one field received specific scores for each field based on recommendations. One hospital can be represented in more than one list. The preliminary lists were presented to a global expert board, which serves in an advisory role for validation.
