The purpose of ISIM is to promote scientific knowledge and unity in Internal Medicine, to further the education of young internists and to encourage friendship between physicians from all over the world.

At a time when Internal Medicine is threatened by increasing sub-specialization, ISIM tries to strengthen its position as an eminent integrating part of global health sciences.

The main activity of ISIM is the organization of the Biannual International Congress of Internal Medicine.

The last congresses took place in Manila (1996), Lima (1998), Cancun (2000), Kyoto (2002), Granada (2004), Taipei (2006), Buenos Aires (2008), Melbourne (2010), Santiago de Chile (2012), Seoul (2014) and Bali (2016) and Cape Town, South Africa (2018). Future congresses will be held in Cancun, Mexico (2020), Moscow, Russian Federation (2022) and Prague, Czech Republic (2024).

The International Congresses of Internal Medicine always were outstanding events with a large attendance from the whole world. Especially when located in countries not privileged with easy international scientific exchange, the congresses give a very welcome opportunity to see and hear leading experts from all over the world.


The activities of ISIM are managed by an Executive Committee, which consists of twelve members.

As a member of the Council of the International Organisation of Medical Societies, ISIM actively co-operates with the World Health Organisation.
