- By removing the contractions and replacing the informal words 'gonna' and 'high tail.'
Explanation:
As per the question, the given sentence contains an informal language which is clearly reflected through the use of contractions('patient's, doesn't) as well as uses an informal language(gonna, high tail). In order to revise it for including it in an academic text the contractions must be removed and the informal words must be replaced. Thus, these changes make the sentence look more formal and lexical(academically) and it reads as;
'The patient is not going to see the doctor if does not reach to the hospital on time'.
