There is a general misperception that a data conversion brings over all the patient data. However, due to cost and complexity, only patient demographics and sometimes some basic medical data elements — are typically converted to a new EHR system.
But, what about the rest of the patient data? To leave the legacy system up and running in read-only format is both costly and a technical risk.
The main difference between a patient data archive and a conversion is data volume. A patient data archive includes most if not all of the data in its full integrity. This all-inclusive long-term storage and medical data archiving of patient data adheres to state and federal medical record retention regulations for protected health information (PHI).
