However, we have to be very careful when we allow free text in archetypes because more free-text fields would have less control over data quality. Currently, data quality is an issue and I believe that archetypes will play a very important role in resolving this issue. However, if we provide more free-text fields than necessary, then we may loss one of the advantages of using archetypes. Even though all text fields can be either free-text or coded text, there should be some rules/guidelines suggesting what kinds of fields can be free-text, coded-text or both. Whether a text field is defined appropriately should be assessed during archetype governance process. What I am saying is that carefully defining a text field is not only for the purpose of DSS, it is also for data quality control.
