Question

I am working on a medical php application which will be implemented at national level.
It will be used by multiple hospitals and the patient record will be centralized i.e every hospital will be accessing and adding the patient records into same database.

I want that there should be only 1 record of a patient without any duplication. Simply speaking no hospital can again enter the 2nd record for same patient but in order to make it possible I need to know which criteria should we use which will remain fix throughout the entire lifetime of a patient. Only 2 are there in my mind i.e Name and Date of birth.

What other criterias can be there? I dont want to use mobile numbers and phone numbers etc. Moreover infants cant be having it. I need the criteria which will be there for every patient and unique.

Please give me your suggestions or any other better way to implement this functionality?

Answer 1

Combination of name, date of birth, blood group, place of birth etc., can be tried.
