If the system has been configured in such a way that, along with printing the summary of the visit by the doctor, the summary was automatically saved in the archive in the form of a PDF file signed by the doctor, then the "EHR archive" functionality from the "Surgery" menu allows one to view the digitally signed archive of electronic health records of patients created in this way. After selecting this functionality, a list of units is displayed, from which the documentation can be found in the digital archive. After clicking on the unit a list of clinics in the given unit displays underneath. After clicking on the clinic, a list of the medical staff in the given clinic displays underneath. After clicking on the medical staff, a list of patients of the given staff in a given clinic displays underneath. After clicking on the patient, a list of dates of his visits to the given staff in the given clinic displays. After clicking on the date of the visit, a list of links to PDF files of the patient's electronic health records is displayed. More than one link at a single visit indicates that modifications have been made to the documentation and subsequent links are subsequent versions of the documentation.
