Actually I have already Googled a lot on volunteering abroad in health care for many decades, and there are RPCVs who work towards creating voluntourism experiences more responsive to local needs. Here an article I found just now:
5 myths about voluntourism talks about both the negative and positions aspects. I still think that it is very a la mode of fashion right now to slam voluntourism in certain situations, a lot of this sort of work is done by retired people who want a more active vacation that might have a better impact than just going sight-seeing and it lets you work with locals.
People might as well slam volunteer work in the US:
1. Don't be a volunteer paramedic (even though rural areas are hurting for them) you're taking jobs away from people!
2. Don't volunteer to read to kids at schools, you'll take a job from teachers and it is just 2 hours a week and you won't have a sustainable impact!
3. Don't be a volunteer nurse with hospice, you'll take somebody's job!
4. Don't be a volunteer physician or work for lower rates at a community HIV center, your work isn't sustainable without addressing the structural inequities first! Please spend your time on the weekends on the golf links as your part of the problem!
Please.
I'll finished my life with maybe 4-6 years of health care work in developing countries, much less than what I wanted. I've seen the work of Harvard trained physicians who speak the local language and travel between the Harvard hospitals and the developing world, following in the model of Paul Farmer. Everybody had to start somewhere, he probably spend just a short amount of time in Haiti and I'm glad nobody piled on him after he got off the plane.
I think this sort of work should be facilitated, be it 3 months or two years or more.
