Primary Care and Health Services

Care may refer to:

Health is the ability of a biological system to acquire, convert, allocate, distribute, and utilize energy with maximum efficiency. The World Health Organization (WHO) defined human health in a broader sense in its 1948 constitution as "a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity." This definition has been subject to controversy, in particular as lacking operational value, the ambiguity in developing cohesive health strategies and because of the problem created by use of the word "complete", which makes it practically impossible to achieve. Other definitions have been proposed, among which a recent definition that correlates health and personal satisfaction.

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.
