Built from system timestamps
Most case chronologies take their times from the notes. In a negligence case where the documentation itself is in question, that repeats the problem: the times in a back-charted note are whatever the author wrote. An audit-trail chronology anchors each event to the time the system recorded, then shows the charted time beside it.
What each row shows
Charted time and system time
The time an entry says it describes beside the time the system recorded it being filed, so gaps between them are visible at a glance.
Who was in the chart
Access events showing which users viewed a result, an order, or a note, and when, which matters when the question is who knew what.
Every version of disputed entries
Edits, addenda, and deletions placed at the moment they happened rather than folded into the final text.
Sources for every row
Each line cites the production page or audit report it came from, so the chronology can be checked and used as the basis for an exhibit.
The simulated demonstrative report shows the format with fictional data.
Written for a jury to follow
Raw audit logs run to thousands of lines of user IDs and event codes. The chronology keeps only the events that bear on the disputed period, labels each in plain language, and keeps the underlying log citations for anyone who wants to check them. It is the same material an EMR expert witness would explain in a deposition or at trial, organized so the explanation can be followed.
Where it fits
A chronology is usually the organizing exhibit for a record alteration analysis and for any spoliation investigation. Getting the data starts with the request; the EMR discovery guide covers the language.
Common questions
How is an audit-trail chronology different from a medical chronology?
A medical chronology summarizes the care described in the chart. An audit-trail chronology reconstructs when the chart itself was created, viewed, and changed, from system metadata. The two work together: your clinical reviewers address the care, and this addresses the documentation.
What records are needed to build it?
The audit trail for the relevant dates and the chart as produced, at minimum. The access log, note revision history, and order and result timestamps make the chronology more complete.
Can the chronology be used at trial?
It is built to support testimony and demonstrative exhibits, with every row sourced to the production. Whether and how it is offered is counsel's decision under the forum's rules.
