The mission of the Society is to develop peri-operative care and to improve recovery through research, education, audit and implementation of evidence-based practice. Below is short description of how the ERAS®Society was developed and some highlights from its history.



HISTORY 1Ken Fearon and Olle Ljungqvist met in London at a nutrition symposia and decided to start a collaborative group on peri-operative care.






The ERAS® Society has its roots in what was called the ERAS® Study Group.  Comprised of leading surgical groups, the ERAS® Study Group was assembled by Professor Ken Fearon, Univ Edinburgh, UK and Professor Olle Ljungqvist, Karolinska Insitutet, Sweden in 2001 to further develop ideas put forth in the 1990’s by Professor Henrik Kehlet, Univ Copenhagen. Denmark concerning the concept of multimodal surgical care. In addition to the above, Profs Arthur Revhaug, Univ Tromsö, Norway Profs Martin von Meyenfeldt and Cornlius deJong, Univ Maastricht, The Netherlands was the original members of the ERAS® Study Group. The ERAS® Study Group soon discovered that there were a variety of traditions in use in different units.  There was also was a great discrepancy between the actual practices and what was already known to be best practice, based on the literature.  This prompted the group to examine the process of change from tradition to best-practice.



HISTORY 2The 1st ERAS Symposia was held in Stockholm at Ersta hospital, Stockholm. In the foreground of the picture are Dr Mattias Soop, Sweden one of the main organizers and Prof Cornelius deJong, the Netherlands.





The ERAS Study Group developed and published an evidence-based consensus protocol for patients undergoing colonic surgery (Fearon et al, Clin Nutr 2005).



The group published data showing that just adding a protocol was not sufficient to change practice to ERAS. (Maessen et al, Br J Surg, 2007)



HISTORY 3The ERAS® Study Group updated the evidence base to include rectal surgery (Lassen et al. Arch Surg, 2009). In the picture are Ken Fearon (UK), Kristoffer Lassen (N), Olle Ljungqvist (SE), Jonas Nygren (SE), Arthur Revhaug (N), and Maarten von meyend feldt (NL).
