The basic structure of internal medicine as a specialty can be confusing since there are so many options for practice focus within the specialty. However, all internists share a basic core of training that forms the foundation for whichever discipline within internal medicine they choose to pursue.
Basic training in internal medicine is three years of residency (termed ‘categorical’ training) following medical school. Following completion of three years of training, residents are eligible for board certification in internal medicine. About half of the country’s internal medicine residents choose to practice General Internal Medicine. General internists are capable of functioning in a number of different roles. For example, many focus on ambulatory practice and may serve as primary care physicians, following patients longitudinally for their ongoing medical care. Others may spend a majority of their time caring for hospitalized patients in the role of hospitalist (over 90% of hospitalists are general internists). However, many general internists care for both ambulatory and hospitalized patients in a very wide variety of practice models.
Others choose to pursue additional training beyond the basic three years of residency training, subspecializing in a particular area of interest within internal medicine. Some of the subspecialties of internal medicine and their associated area of interest include:
Internal medicine training may also be combined with training in another specialty, leading to board certification in both fields. These dual training programs are generally structured to be shorter than the time it would take to complete an independent residency in both fields, and graduates of these programs are particularly qualified to care for patients in both areas of focus. Examples include internal medicine and pediatrics, emergency medicine, and psychiatry.
Internists may also develop specific skills in other areas of interest, although individuals may achieve qualification in these areas from backgrounds other than internal medicine. Examples include geriatrics, sports medicine, hospice and palliative care medicine, and sleep medicine.
