The Physician Assistant
What is PA?
Your PA is a new and highly qualified health care professional who works under the supervision of your doctor.
What does a PA do?
Your PA may evaluate you by taking your medical history, doing physical examination, and ordering laboratory studies or x-rays, and will be involved in treating you. Your PA concentrates on treating the more commonly found illnesses and medical problems, and will consult with or have you see your doctor whenever it is necessary. This team approach helps you get the best possible care and keeps medical costs down.
Quality Care
Your doctor can vouch for the high quality of care your PA gives. Most important, so can the patients. Many government and private studies show that PAs give care equal in quality to that of physicians in the same setting. This is possible since your PA is well-trained, is working with your doctor as part of a team, and because your PA will probably be able to spend more time with you than your doctor can.
Training and Licensure
All Physician Assistants in this state must be licensed and pass a rigorous national examination before they are allowed to practice. They must be graduates of state-approved programs located in or associated with medical schools. Their training is intensive and broad, with an emphasis on direct patient care.
