What Is An Osteopathic Physician (D.O.)?

In the U.S. there are two types fully qualified physicians that can diagnose illnesses, prescribe medications and perform surgery – the M.D. (allopathic physician), and the D.O. (osteopathic physician). Both the M.D. and D.O. have completed four years of medical school followed by 3 to 8 years of internships, residencies and fellowships, depending on the specialty they have chosen. Both the M.D. and the D.O. must pass examinations to be licensed in their state. Where an osteopath differs from an M.D. is the approach to treating the patient as a whole rather than just treating only the symptoms. This is not the same as holistic medicine.


What is a Nurse Practitioner?

A nurse practitioner is a registered nurse who has completed advanced education and training to provide patient care including diagnosing and managing acute and chronic conditions. Nurse practitioners can provide some of the same care as physicians and maintain close working relationships with collaborating physicians and will refer to specialists as needed. Their goal is to provide quality care to patients with an emphasis on prevention, wellness, and patient education


About Geriatrics

Geriatrics is the subspecialty of internal medicine concerned with the health and well-being of older adults. Geriatricians must complete seven or more years of medical school and postgraduate training and become board certified in Internal Medicine. Then, for an additional year they study conditions specific to aging, including geriatric assessment and rehabilitation, preventive medicine, management of patients in long-term care settings, and psycho-social, ethical, legal, and economic issues pertinent to geriatric patients.


What Geriatricians Do

Geriatricians diagnose, treat and manage diseases and conditions that require a special approach when dealing with older adults. They give special attention to situations of special concern, including falls, incontinence, preoperative assessment and post-operative management, cerebrovascular disease, dementia, sensory impairment and other cognitive and affective changes that occur with aging.


When You Need A Geriatrician

Geriatricians often become the primary physician for older adults. If this is not the case, your primary physician might refer you to a geriatrician when a problem associated with aging requires special attention. In some cases, a family member might recognize a need for a geriatrician and suggest you consult one.


How Geriatricians Work With Other Physicians

If geriatricians are not serving as your primary care physician, they often work with other physicians, advising them about a specific diagnosis or treatment plan. More often, geriatricians act as primary care physicians, relying on many skilled professionals and other subspecialists of internal medicine, nurses, physical and occupational therapists, psychiatrists, psychologists, pharmacists, and social workers.
