Paper medical records require physical space to be stored in contrast to electronic medical records kept on centralised servers. Medical information for a huge number of patients may be stored on a single physical storage server, but the tangible files needed to support that capacity take up a lot of room. These are priceless data vaults in the medical record department and need to be handled with care; it is not just a case of allocating a room and dumping files in it. So, to maintain data integrity, you probably need temperature-controlled spaces, and other tools.
