Health care

Health care or healthcare is the protection or improvement of health via the diagnosis, treatment, and prevention of sickness, illness, injury, and other physical and mental impairments in human beings.

It includes the work completed in providing primary care, secondary care, and tertiary care, as well as in public health. 

Health care delivery

The delivery of present health care depends on groups of trained professionals and paraprofessionals coming together as interdisciplinary team. This includes professional in medicine, psychology, physiotherapy, nursing, dentistry, midwifery and allied health, plus several others such as public health practitioners, community health workers and assistive personnel, who systematically give personal and population-based preventive, curative and rehabilitative care services.


Primary care

Primary care refers to the work of health professionals who act as a first point of consultation for all patients within the health care scheme. Such a professional would usually be a primary care physician, such as a general practitioner or family doctor, a licensed independent practitioner such as a physiotherapist, or a non-physician primary care source (mid-level provider) such as a physician assistant or nurse practitioner. Depending on the locality, health system association, and sometimes at the patient’s discretion, they may see another health care professional first, such as a pharmacist, a care for (such as in the United Kingdom), a clinical officer (such as in parts of Africa), or an Ayurvedic or other customary medicine expert (such as in parts of Asia). Depending on the nature of the fitness condition, patients might then be referred for secondary or tertiary care.

Primary care is often used as the word for the health care services which play a character in the local community. It can be provided in different settings, such as Urgent care centers which provide services to patients same day with appointment or walk-in bases.

Physicians in this model bill patients honestly for services, either on a pre-paid monthly, quarterly, or annual basis.

Secondary care is the fitness care services provided by medical specialists, dental specialists and other health professionals

who usually do not have first contact with patients: for example, cardiologists, urologists, endodontists, and verbal and maxillofacial surgeons.

The term “secondary care” is sometimes used synonymously with “hospital care”. However, several secondary care providers do not necessarily work in hospitals

Secondary care

Depending on the association and policies of the national health system, patients may be required to see a primary care provider for a referral before they may access secondary care.
