Each vendor strives to make their system better and different then their competitors. And to that end they all try to add in features that make it easier for a doctor to enter the information that is important to them. However, occasionally this can cause problems when a clinic wants to utilize the data stored in their EMR. This issue can take many forms, using RTF tags to record data (i.e. using Bold to denote the patient response (Yes/No), storing data in custom forms that cannot be queried or storing data in PDF forms. These are just some of the various ways we have seen custom data types cause issues for a clinic when they are looking to utilize their data or move to another EMR.
