Nursing is a profession within the health care sector focused on the care of individuals, families, and communities so they may attain, maintain, or recover optimal health and quality of life.

Nurses may be differentiated from other health care providers by their approach to patient care, training, and scope of practice.

Nurses practice in many specialisms with differing levels of prescriber authority.

Many nurses provide care within the ordering scope of physicians, and this traditional role has shaped the public image of nurses as care providers.

However, nurses are permitted by most jurisdictions to practice independently in a variety of settings depending on training level.

In the postwar period, nurse education has undergone a process of diversification towards advanced and specialized credentials, and many of the traditional regulations and provider roles are changing.

A health professional, health practitioner or healthcare provider (sometimes simply "provider") is an individual who provides preventive, curative, promotional or rehabilitative health care services in a systematic way to people, families or communities.

A physician, medical practitioner, medical doctor, or simply doctor is a professional who practises medicine, which is concerned with promoting, maintaining, or restoring health through the study, diagnosis, and treatment of disease, injury, and other physical and mental impairments.

Physicians may focus their practice on certain disease categories, types of patients and methods of treatment—known as specialities—or they may assume responsibility for the provision of continuing and comprehensive medical care to individuals, families, and communities—known as general practice.

Medical practice properly requires both a detailed knowledge of the academic disciplines (such as anatomy and physiology) underlying diseases and their treatment—the science of medicine—and also a decent competence in its applied practice—the art or craft of medicine.

A hospital is a health care institution providing patient treatment with specialized medical and nursing staff and medical equipment.

The best-known type of hospital is the general hospital, which typically has an emergency department to treat urgent health problems ranging from fire and accident victims to a heart attack.

A district hospital typically is the major health care facility in its region, with large numbers of beds for intensive care and additional beds for patients who need long-term care.

Specialised hospitals include trauma centres, rehabilitation hospitals, children's hospitals, seniors' (geriatric) hospitals, and hospitals for dealing with specific medical needs such as psychiatric treatment (see psychiatric hospital) and certain disease categories.

Specialised hospitals can help reduce health care costs compared to general hospitals.
