In 1855, the first Jewish hospital in America, Jews' Hospital of New York, admitted its first patient. The phenomenon of Jewish hospitals may have been linked to the experience in Europe, where restrictions were placed on the number of Jewish patients admitted to public hospitals, and even in America where quotas were placed on Jewish doctors studying and practicing. Today, Jewish hospitals are found in dozens of major cities including Los Angeles, Cincinnati and Baltimore. These hospitals are often ranked as tops in their field; for example, Barnes Jewish Hospital in St. Louis is the largest hospital in Missouri, is regarded as one of the nation's top three medical schools, and is ranked as one of America's top-10 hospitals overall.
