Duplication Solution - Duplicate Patient Registration Warning

[Diama1]

Issue

When a user is registering a patient who has the same date of birth or ID number and resides in the same village as an existing patient, they should be alerted about the potential duplicate. The warning message will include the name and parent of the existing patient, along with the reason for the suspicion (matching date of birth or ID number and same village).

Todo

• Create the screen as per designs.
• Implement the logic for detecting potential duplicate patients.

a patient who has the same date of birth or ID number and resides in the same village as an existing patient

Since national ID number is unique (it is, right?), I don't see the need to make a check for village. If we find existing patient with same national ID, we will present the warning.
Also, I don't really see how date of birth can be used here, since theoretically, there can be several patients from same village born on same day (twins, for example).

So, as I see it, only parameter checked here needs to be national ID.

Tell me if changes are required.
