In Family Medicine, there are multiple disciplines in which additional or specialized education can be obtained depending on the individual interests and career goals of a resident. There are several specialty disciplines that have become established, specific tracks known as "Areas of Concentration" (AOCs). Common AOCs include Women's Health, Sports Medicine,Geriatrics, Dermatology, Academic Family Medicine, and Global Health. Operational Medicine is a popular AOC that is specific to the military. This will allow residents with special interests in these areas to individualize their educational experience. There will likely be additional AOCs in the future. At least 2 months or 200 hours of training is required in the AOC, above and beyond the RRC requirements. Additional requirements for the AOCs are outlined in the Resident Handbook. Other AOCs exist, and, if a resident has a specific idea for an AOC, that idea can be submitted for consideration.
