Presenting Clinical Material –
Golden Rules





Always maintain patient confidentiality – code
of ethics as a health care practitioner e.g. Mrs
Beryl Thomas – Mrs BT or Mrs T.
Be concise – present only relevant material.
Relevant should include negative or nil findings
e.g. allergies, where appropriate
Present material in a logical and structured
manner
Provide detail where appropriate e.g. smoking
habit.
Structure of Information

Brief into of page – age, gender & problem
C/O = complains of
HPC = history of presenting complaint
PMH = past medical history
O/E = on examination – may include a RoS
(review of systems)
FH = family history
SH = social history

Medical Terminology – learning the language.
(http://ec.hku.hk/mt/)
prefix
The
of a word is before the main part of the word.
If you can recognize the meaning of the prefix, you will be
able to guess the word's definition more accurately.
suffix
A
follows the end of a word and forms a new word.
A suffix provides important clues about a word's definition.
For instance, the suffix, 'pathy', means disease.
In most cases when you see a word ending in 'pathy', you
know it refers to a disease, as in 'angiopathy', which means
disease of the blood vessels.
Understanding Terminology
Hyperkalaemia
Prefix = Hyperkalaemia = high
Root = Hyperkalaemia = potassium
Suffix = Hyperkalaemia = blood
Meaning = raised potassium concentration in the blood.
The Prefix

Describes position

Provides a description

Describes number and measurement
