Health Care Definition:
Health care - (healthcare) is defined as the diagnosis, treatment, and prevention of disease, illness, injury, and other physical and mental impairments in human beings. Health care is delivered by practitioners in allied health, dentistry, midwifery (obstetrics), medicine, nursing, optometry, pharmacy, psychology and other health professions. It refers to the work done in providing primary care, secondary care, and tertiary care, as well as in public health.
Primary care - Refers to the work of health professionals who act as a first point of consultation for all patients within the health care system.
Secondary care - The health care services provided by medical specialists and other health professionals who generally do not have first contact with patients, for example, cardiologists, urologists and dermatologists.
Tertiary care - Specialized consultative health care, usually for inpatients and on referral from a primary or secondary health professional, in a facility that has personnel and facilities for advanced medical investigation and treatment, such as a tertiary referral hospital.
Quaternary care - The term quaternary care is sometimes used as an extension of tertiary care in reference to advanced levels of medicine which are highly specialized and not widely accessed.
Home and community care - Many types of health care interventions are delivered outside of health facilities. They include many interventions of public health interest, such as food safety surveillance and distribution of needle-exchange programs for the prevention of transmissible diseases.
