Internal Medicine is a multidimensional specialty devoted to the comprehensive and specialized care of adults, with internists (physicians who practice internal medicine) frequently referred to as "Doctors for Adults".  Internists are committed to the life-long process of understanding the scientific basis of human health and disease and the compassionate application of this knowledge to patient care, thus linking knowledge of the biomedical sciences to clinical medicine.

As the world's largest medical specialty, internal medicine is extremely broad-based with internists functioning as researchers, practitioners caring for patients as both generalists and in 13 subspecialty areas in both outpatient and inpatient settings, providing primary care as well as consultative services, working with young adults and the very old, and participating extensively in the training of tomorrow's physicians.

The American College of Physicians (ACP) is the national organization of internists.  With a membership of 126,000, it is the largest medical specialty organization and second largest physician group in the United States.  The mission of the ACP is to enhance the quality and effectiveness of health care by fostering excellence and professionalism in the practice of medicine.  More information about the ACP and internal medicine is available at their website.    

Penn State Health Medicine embodies each of the core values of internal medicine through it's tripartite mission of patient care, research and medical education.
