Hierarchy (Medicine)

Hierarchy (pronounced: /ˈhaɪərɑːrki/) is a term used in various branches of medicine to denote a system of organization or ranking based on certain principles or rules. The term is derived from the Greek words 'hieros' meaning 'sacred' and 'archein' meaning 'to rule'.

Etymology

The term 'Hierarchy' is derived from the Greek words 'hieros' meaning 'sacred' and 'archein' meaning 'to rule'. It was first used in English in the 14th century to denote the three divisions of angels in heaven. In the context of medicine, it has been used since the 19th century to denote a system of organization or ranking.

Usage in Medicine

In medicine, hierarchy often refers to the ranking of evidence in evidence-based medicine, where different types of studies are ranked according to their reliability. For example, systematic reviews and meta-analyses are considered to be at the top of the hierarchy, while case reports and expert opinions are at the bottom.

Hierarchy can also refer to the organizational structure in healthcare settings, such as hospitals, where different roles and responsibilities are ranked according to their importance and authority. For example, in a hospital, the hierarchy may start with the chief executive officer at the top, followed by doctors, nurses, and other healthcare professionals.
