I don't think there's going to be a simple answer of one size fits all for all areas. I imagine that we have to look at the resources that are available in each situation, in each country of interest. There may be training available within that country. Maybe nearby there are facilities. But perhaps you're talking not only about ways of augmenting what training and education are available to ensure quality care, but also about selecting suitable people from the communities involved and bringing them to that centre and making sure they get the training and getting them back out there. Of course I think I see tremendous cultural advantages when people actually know the language, know the community, and know what it's like there. Bringing in people from another culture creates other kinds of challenges.
But I wonder, since you both have experience in the field, whether you would be able to provide specific examples from your own experience in the field of programs of this nature.
