Providing medical care to older people can be complicated. People often have many different health care practitioners at different locations. Travel and transportation issues become more difficult as people age. The drugs that are covered by the Medicare prescription drug plan vary between insurance companies and change frequently. Assistance by a team of health care practitioners under the leadership of a primary care practitioner or a practitioner who specializes in the care of older people (such as a geriatrician) is the best way to deal with these complexities. However, this ideal solution is often difficult to achieve.
