To deliver medicinial aid wherever aid is needed throughout the world, especially where human suffering is greatest.
To quote their website:
"We are Doctors Without Borders/Médecins Sans Frontières (MSF). We help people worldwide where the need is greatest, delivering emergency medical aid to people affected by conflict, epidemics, disasters, or exclusion from health care."
Doctors without Borders is comprised of a diverse range of both medical professionals, technicians, and administrators.
The organization is so large and diverse in its portfolio of accomplishments that it is hard to pinpoint through their research precisely how they approach disasters. However, their overall message is that they help where help is needed most and supply quality medical care for the people there. They seem to have a wholistic approach wherein they supply all care post-disaster instead of focusing on the immediate effects of the disaster.
It was a new way of addressing disaster in 1971 when it was founded.
“It’s simple really: go where the patients are. It seems obvious, but at the time it was a revolutionary concept because borders got in the way. It’s no coincidence that we called it ‘Médecins Sans Frontières.’”
The organization was founded because of the experience of volunteer Red Cross doctors. These doctors wanted to tell others what they had seen and to help bring more aid to those that are suffering.
Through grants and individual donations. Honestly I have no idea, I tried searching their financial documents but it didn't really tell me anything. They don't publish who donates to them.
They seem to support their approach by their own success.
They have incrediable amounts of research over the course of their history. Within the last year, they published a paper on the care for victims of sexual violence. This article address how they have been handling sexual violence over the past decade as well as the pressure it puts on the orgnaization and its need to continue its aid.
Doctors without Borders has facilities in many countries already established for humanitarian aid. For instance, they had been in Haiti since 1991, so their assistance in 2010 was aided by their already established position there. In that case they upped their projects within the country in response to the disaster.
They generally work in the lowest socio-economic groups, which tend to be the most in need for medicial aid.
