The International Association for Ambulatory Surgery (IAAS) was founded in 1995 and is a registered charity in Belgium. Its main aim is to promote the worldwide development of high quality ambulatory surgery (aka: day surgery). In pursuit of this, the IAAS has had a number of achievements. We started the publication of the first international peer reviewed journal on ambulatory surgery. Entitled Ambulatory Surgery, the journal was first published in paper form in 1993 and is now freely available in electronic format at

The foundation of the IAAS coincided with its first international congress in Brussels. Since then biennial congresses have been held at different venues around the world. The IAAS has also been involved in promoting the practice of ambulatory surgery at many national conferences in Europe, North and South America, Australasia, Asia and Africa.

Politically, the IAAS has lobbied organizations such as the European Union, the World Health Organisation, the Organisation for Economic Co-operation and Development and national governments on the benefits and management of ambulatory surgery. An example of this work is the booklet Day Surgery Making It Happen published in 2007 by the World Health Organization on behalf of the European Observatory on Health Systems and Policies in collaboration with the IAAS. As a consequence of these activities the number of national ambulatory surgery associations has increased as has the amount of ambulatory surgery performed in most countries.
