Getting to Know Your Healthcare Providers

IMAGE Most of us are familiar with MD after a doctor's name. This stands for doctor of medicine and signifies that this person has completed 4 years of medical school. But do you know if your doctor is a DO? And what about the other people checking vitals, writing prescriptions, and filling in charts—PAs and NPs—what type of training do they have and what services can they offer?

MDs and DOs

A DO is a doctor of osteopathic medicine. MDs and DOs are similar in many ways. Here are some requirements that both MDs and DOs must complete:
  • Complete 4 years of medical school
  • Complete residency programs, which involves 3-8 years of additional training
  • Pass state licensing exams to treat patients, prescribe medication, and perform procedures
  • Practice in accredited hospitals and medical centers
  • Earn continuing education units to remain certified
There are also some distinctions between these types of doctors. For example, DOs:
  • Use may a technique called osteopathic manipulative treatment (OMT). With OMT, DOs use their hands to manage their patient’s injuries and illnesses.
  • Receive extra training in the musculoskeletal system. This system consists of interconnected muscles, tendons, ligaments, and bones. DOs are trained in a philosophy of medicine that places great emphasis on the importance of this system to the maintenance and restoration of health.
  • Focus on primary care medicine. The majority of DOs practice in areas of primary care, such as pediatrics, family practice, obstetrics/gynecology, and internal medicine.
  • Are trained to spend more time considering the broad range of factors affecting health. MDs may also have this holistic approach.

Physician Assistants

A physician assistant (PA) is a health professional who is licensed to practice medicine under the supervision of a physician. Some of the duties that a PA can do include:
  • Obtain a medical history and perform a physical exam
  • Diagnose and treat illnesses and minor injuries
  • Order and interpret tests, such as lab work and x-rays
  • Counsel on preventive health and lifestyle practices
  • Assist in surgery
  • Prescribe medications
A PA can work in any area of medicine, but the majority work in primary care medicine, such as pediatrics, family practice, obstetrics/gynecology, and internal medicine.To become a PA, a person must complete an accredited PA educational program and pass a national certification exam. The typical PA program takes about 2 years. The majority of students have a bachelor's degree and experience in the healthcare field before admission to the program. Education consists of classroom and laboratory instruction in the basic medical and behavioral sciences, as well as clinical rotations in different medical fields. When certified, PAs take continuing medical education classes and are regularly retested on their skills.
