The language should be always presented in a form understandable by the intended users.
To make information presented in the EHR understandable, use words that are familiar to the users. Words that are more frequently seen and heard are better and more quickly recognized. The use of made-up words and jargons should be avoided. If highly specialized language is to be used, make sure the intended users are specialized group that can understand. Additionally, the system should use the standard meanings of words in the clinical setting. For example, “vitals” in most medical settings are measures of various physiological statistics (i.e. body temperature, pulse rate, respiratory rate, and blood pressure). Avoid using other meanings of this word that are likely to confuse the users.
The EHR should also use user-centered language, in which words are presented in users’ perspective. This way of language representation is always simple and direct, and thus easy for user to understand. For example, “You can search the meaning of the word by clicking the link” is a better representation than “The link is for you to search the meaning of the word”. Abbreviations can sometimes be difficult to understand and should be used with caution.
