When a detail looks wrong, the first question is who changed it and when. The record's history answers that for every edit, including ones that failed.
Change history of the details
Every edit to a patient's details is kept. On the Details section, select the Last edited by line above the record to open Change history. Each entry names the field, shows the old and new value, who changed it and when. Use it to find out what an address said before it was corrected, or who changed a date of birth. Close returns to the details.
Appointments have their own change history on each appointment, under the patient's Appointments section and on the calendar.
Who has looked at the record
The History button on the record header opens the access log for this patient: who viewed, downloaded or printed something and who created, changed, archived or deleted anything on the record, with the date and a note of what, plus actions that failed. Load more goes further back. The clinic-wide version, across all patients, is the audit log.
