Rural America is struggling to attract and keep doctors. One reason: most doctors end up practicing where they train, which is usually in a metropolitan area. What's more, many rural hospitals are closing. Add to that the fact that some rural residents face higher rates of chronic disease. It's a crisis in the making for rural communities. Blue Cross and Blue Shield of Nebraska asked this question: why not train doctors in small towns? An investment in that strategy is paying off, providing thousands of dollars in scholarships for students who agree to stay and practice in rural areas.
