Wikipedia
Primary care is the day-to-day healthcare given by a health care provider. Typically this provider acts as the first contact and principal point of continuing care for patients within a healthcare system, and coordinates other specialist care that the patient may need. Patients commonly receive primary care from professionals such as a primary care physician ( general practitioner or family physician), a nurse practitioner ( adult-gerontology nurse practitioner, family nurse practitioner, or pediatric nurse practitioner), or a physician assistant. In some localities such a professional may be a registered nurse, a pharmacist, a clinical officer (as in parts of Africa), or a Ayurvedic or other traditional medicine professional (as in parts of Asia). Depending on the nature of the health condition, patients may then be referred for secondary or tertiary care.
