...bring the education to him. And in as low-tech a way as possible, since he doesn't have Internet—or even library—access. That's the idea behind the Blue Trunk Library, a project designed to provide continuing healthcare education to workers in developing countries. From the article on PLoS Medicine:
The BTL is “a ready-to-use documentation module”  of about 150 WHO and non-WHO books and manuals fitted into a blue metal trunk (Figure 1). The materials are arranged and filed in such a way that users can easily identify the ones that they need. Fourteen topics have been chosen using a basic classification code, e.g., General Medicine and Nursing (100), Community Health (110), and these codes are written on each filing box.
The article says that training sessions have been organized in 14 countries, including Burundi, Guinea, Ethiopia, Republic of Congo, Mauritania, and Mali. While there still are language-related problems—it's more difficult to find appropriate texts in some languages than others—this is a good way to try to improve healthcare in difficult areas by providing training any way they can.
