The International Society of Internal Medicine (ISIM) was founded in 1948 in Basel, Switzerland. Its purpose is to promote scientific knowledge and unity in internal medicine, to further the education of young internists and to encourage friendship between physicians in all countries.
Membership to ISIM is of two types: Society Membership, and Honorary Membership. Today, ISIM comprises the national societies of internal medicine of over 60 different countries throughout the world as society members. Recently, ISIM was successful in recruiting a new society member: The Ghana Society of Internal Medicine was admitted as a society member in January 2008 and the Serbian Society of Internal Medicine was admitted in June 2008. ISIM is very pleased that the Chinese Society of Internal Medicine will also become a member of ISIM very soon.
