When registering a new client, you are only presented with a list of clients for which you have access to see. If the client I am registering has an existing chart in a program that I do not have access to, then I would not see that they already exist.

The system also needs a way to merge clients in addition to more controls to prevent duplicate clients in the system.

When registering a new patient, a user is provided a display of already registered patients with same 'names'.

If I were trying to register a patient with the last name of 'Smith', I am presented all existing patients with the name 'Smith' and their DOB and SS# (if captured). This is done to provide the user a view into patients who may already be entered into the software.

I would agree that TenEleven needs additional logic to prevent duplicate Patient Detail records. In our experience, it is the variations in Patient First Name / Last Name entries that can lead to duplicates, especially with compound name elements. TenEleven should normalize name elements (i.e., remove spaces, dashes, and apostrophes) from compound name elements then evaluate for potential duplicates.
