Information

PRIMARY CARE

A primary care provider (PCP) is a person you may consult or see first for checkups and health problems. PCPs can help manage your overall health. If you have a health care plan, find out what type of practitioner can serve as your PCP.

• The term "generalist" often refers to medical doctors (MDs) and doctors of osteopathic medicine (DOs) who specialize in internal medicine, family practice, or pediatrics.
• Obstetrician/Gynecologists (OB/GYNs) are doctors who specialize in obstetrics and gynecology, including women's health care, wellness, and prenatal care. Many women use an OB/GYN as their PCP.
• Nurse practitioners (NPs) are nurses with graduate training. They can serve as a PCP in family medicine (FNP), pediatrics (PNP), adult care (ANP), or geriatrics (GNP). Others are trained to address women's health care (common concerns and routine screenings) and family planning. NPs can prescribe medicines.
• A physician assistant (PA) can provide a wide range of services in collaboration with a Doctor of Medicine (MD) or a Doctor of Osteopathic Medicine (DO) and can also serve as a PCP.

NURSING CARE

• Licensed practical nurses (LPNs) are state-licensed caregivers who have been trained to care for the sick.
• Registered nurses (RNs) have graduated from a nursing program, have passed a state board examination, and are licensed by the state.
• Advanced practice nurses have education and experience beyond the basic training and licensing required of all RNs.

Advanced practice nurses include nurse practitioners (NPs) and the following:

• Clinical nurse specialists (CNSs) have training in a field such as cardiac, psychiatric, or community health.
• Certified nurse midwives (CNMs) have training in women's health care needs, including prenatal care, labor and delivery, and the care of a woman who has given birth.
• Certified registered nurse anesthetists (CRNAs) have training in the field of anesthesia. Anesthesia is the process of putting a person into a painless sleep, and keeping the person's body working so surgeries or special tests can be done.

DRUG THERAPY

Licensed pharmacists have graduate training from a college of pharmacy.

Your pharmacist prepares and processes drug prescriptions that were written by your primary or specialty care provider. Pharmacists provide information to people about medicines. They also consult with providers about dosages, interactions, and side effects of medicines.

Your pharmacist may also follow your progress to check that you are using your medicine safely and effectively.

Pharmacists also can evaluate your health and prescribe medicines.

• Allergy and asthma
