About
Mid-level healthcare practitioners have emerged as a response to a shortage of primary care physicians especially in many rural areas and in inner cities. They also appear to remedy the problem of very high healthcare costs. The question remains however: has the role of the healthcare practitioner increased in importance beyond filling in and cost benefit?
