Primary care physicians provide basic medical care, diagnose and treat common medical conditions, and specialize in preventive medicine. They also refer patients to specialists if necessary. Many health insurance plans require a referral from a primary care physician before seeing a specialist.
A primary care physician is a general practitioner who treats underlying medical conditions. General practitioners administer the required physical checkups and vaccinations. They can help diagnose health problems and provide care or refer patients to specialists if the condition calls for it. I am often the first doctor most patients see when they have a health problem.
In the United States, many health insurance plans require a referral from a primary care physician before a patient can see a specialist. The same is true in many European countries; for example, in Norway every patient is registered with a general practitioner who is their first point of contact. In England and Canada, which offer healthcare as part of a government-sponsored plan, patients are also encouraged to consult general practitioners first.
There are many reasons for requiring patients to see a primary healthcare provider first. Cost containment is one reason, as general practitioners are often less expensive than specialists. Proper diagnosis and referral to the correct specialist is another factor. Patients may not be aware of the cause of their symptoms, and a primary care physician can help identify underlying medical reasons.
Primary care physicians do more than refer patients to specialists; they also provide basic medical care and services. Most diagnose and treat common medical conditions, from strep throat to bacterial infections and simple viruses. These doctors can also read and interpret x-rays, blood and urine tests. They can also help manage the treatment of chronic conditions, including diabetes and high blood pressure.
General practitioners also specialize in preventive medicine. One of their primary functions is to help patients learn to be healthy and maintain appropriate habits to promote overall health. This includes patient education about diet, smoking, and other lifestyle choices. Studies have shown that patients under the care of a primary care physician tend to receive more frequent vaccinations and be better screened for dangerous diseases, including cancer.
In the United States, primary care physicians go through medical school and do their residency in primary care facilities. In Europe, primary health care professionals go through a similar educational path, including attending school and gaining clinical experience as a general practitioner. The residency for these physicians is usually shorter than the residency for other specialties.
