What’s the difference between a medical doctor (MD) and a doctor of osteopathic medicine (DO)?

All licensed physicians, whether they are MDs (Medical Doctor) or DOs (Doctor of Osteopathy), have similar education and training. Both require four-year undergraduate degrees, with an emphasis in the sciences, followed by four years of post-graduate medical education. MDs and DOs both choose specialties after completing their residency programs—which typically calls for an additional two to six years of medical training. They must both pass similar licensing examinations in order to practice medicine. Most important, both MDs and DOs are medical doctors who can prescribe medications, perform surgeries, and treat patients in hospital and clinical settings.

What Is a Nurse Practitioner?

Nurse practitioners (NPs) are registered nurses with advanced education, graduate degrees, and clinical training that enable them to carry out most of the same patient care activities as physicians. In addition to performing physical exams and patient histories, nurse practitioners can order and analyze lab tests, diagnose illnesses, prescribe medications, develop treatment plans, and advice patients on lifestyle changes. Although nurse practitioners can work independently in some states, in California they work closely with physicians, who provide guidance and oversight.
