What to expect working as a doctor at a high-altitude aid post

Over the past 40 years, in an attempt to reduce the morbidity and mortality of altitude illness, a number of volunteer-run, seasonal aid posts have been established at mountain ranges across the world. As each aid post is designed for the local population and tourists at hand, the range of problems seen and services offered vary accordingly. Although each clinic differs on its funding model, the services it offers, how it is staffed, and the interventions available, there are key similarities between each of these clinics. For physicians preparing to travel from their home country to volunteer at such aid posts, there are important preparations that need to be made before embarking on such endeavors. This article describes how to prepare for such work, what to expect, and some of the challenges that one might face.
