A method for securing patient identity comprising accessing an electronic
medical records database including patient data for a plurality of
patients. Each patient in the electronic medical records database is
assigned a unique patient identifier. Patient data for a first patient,
including a first patient identifier, is retrieved from the electronic
medical records database. The first patient is de-identified from the
patient data. De-identifying includes the creation of a first encoded
patient identifier responsive to the first patient identifier. The
de-identifying results in de-identified first patient data and includes
the replacement of the first patient identifier with the first encoded
patient identifier. The de-identified first patient data is transmitted
to a data warehouse system. The method further comprises identifying a
second patient in response to receiving report data that includes a
second encoded patient identifier from the data warehouse system. The
identifying includes the creation of a second patient identifier
responsive to the second encoded patient identifier.
