A Physician Assistant (PA) is a health care professional licensed to provide medical care with physician supervision. PAs practice a medical/physician model of patient care, which centers on treating diseases and emphasizes the biological/pathologic aspects of health, assessment, diagnosis and treatment. In accordance to the regulations of a particular state’s medical licensing board, PAs function as an extension of a supervising physician.
PAs are utilized in any healthcare setting where physicians practice such as primary care, family and community care, and internal medicine practices. They also practice in various specialty care fields such as Surgery, Emergency Medicine, Obstetrics & Gynecology, Radiology, and Pathology. PAs currently provide care to millions of people in all types of health care settings: offices, clinics, hospitals, nursing homes, and long-term care facilities. In addition to private practice settings, they are also heavily utilized in public sector healthcare areas, such as in the prison system and the military.
