The primary health care professional (usually a primary care physician [PCP] or other doctor, nurse practitioner, or physician associate) provides general medical care and is sometimes responsible for coordinating care by other medical specialists and supportive care.

Some health insurance plans require an insured member to a primary care professional. Even if a person''s medical insurance does not require it, having a primary care doctor has many advantages that can lead to better care.

People who have a primary care doctor are less likely to go to an emergency department unnecessarily and less likely to be seen by a doctor they do not know. When people see a doctor they do not know, the doctor may not have all the background information necessary to diagnose and treat the problem. Consequently, the doctor may need to repeat or do unnecessary tests.

Communication is often better and medical decisions are more easily made when people have an established relationship with a primary care doctor. People are more likely to trust a doctor they know and to experience less anxiety when a medical problem develops.

Primary care doctors often have longstanding relationships with their patients and have established mutually acceptable lines of communication. They are familiar with what their patients want and value, how they best receive information, how they cope with adversity, whether they are able to purchase prescribed medications, and which family members they rely on.

Primary care doctors explain what type of care is needed, why it is needed, and how often visits should be scheduled. They provide appropriate preventive health care including vaccinations and can refer people to specialists when needed and coordinate care with other health care professionals.

Some health care plans require people to see their primary care doctor to get a referral before they see a specialist. Obtaining a referral ensures the primary care doctor is informed about a person''s health care needs and ensures that people see the proper specialist and that specialist receives the appropriate background information.

To find a primary care doctor, people can begin by asking friends and relatives for recommendations. Or they can call a medical school or local hospital and ask for a department, such as pediatrics, internal medicine, family practice, or geriatric medicine. Online survey data from patients regarding individual doctors are another source of information but should not be the only source or substitute for personal assessment.

Many health insurance plans limit the choice of doctors and other health care professionals. In such cases, people should consult the plan to obtain a list of participating professionals.

When choosing a primary care doctor, people should consider what is most important to them (for example, friendliness, experience, training, age, thoroughness, patience, or promptness). Some people prefer a doctor who spends extra time with them, even if doing so tends to make the doctor run late keeping office appointments. Other people prefer a doctor who keeps appointments on time, even though doing so may limit the time spent with them. Older adults may want a primary care doctor who specializes in treatment of their age group (a geriatrician). People should look for a doctor they feel comfortable with and have confidence in. For example, for some people, this means ing a doctor who is comfortable using telemedicine.
