That turned out to be a mistake because the words “NIL KNOWN” might seem unimportant, but it contained a hidden logic that’s valuable to the business.
For example, the allergies field may be used to store answers from a patient survey form. Therefore there is an obvious difference between NOT answering a question and answering NO to a question.
Let’s now look at the possible consequences of the data migration process:
1. Migrating “NIL KNOWN”
The nurse can safely carry out care activities without delay.
2. Not migrating “NIL KNOWN”
The nurse may take extra time to confirm that the patient has no food, medical or physical allergies before carrying out care activities.
