Expedition Medicine Advisory Group

What is the RGS Expedition Medicine Advisory Group?

As part of the Society’s commitment to supporting those planning field research and expeditions, the Society has a specialist advice unit, the Expedition & Wilderness Medicine Advisory Group (formerly known as the Medical Cell). This group provides a forum for discussion, information and advice to those operating in remote areas.

Established in 1996, the group's initial remit was to provide medical advice to the Society's overseas field research programmes and, through teaching and research, to reduce the hazards of participating in an expedition or travelling in remote areas.

The Expediiton Medicine Advisory Group has been involved in research into the health risks associated with expeditions, and has been closely associated with several handbooks on Expedition Medicine, including most recently the 2nd edition of the popular Oxford Handbook of Expedition and Wilderness Medicine (OUP, 2015).


What does the Expedition Medicine Advisory Group do?

To improve the quality of information the Expedition Medicine Advisory Group provides, it is involved in developing a series of best practice guidelines. Much of this work is done online and anyone with expertise who can help improve the quality of healthcare in remote areas is encouraged to participate. The Society hosts meetings to debate the guidelines, and to bring together enthusiasts in this exciting area of medicine. 

Current projects include:
