A medical malpractice chronology sets out, in time order and with a page citation for each entry, what providers knew, ordered, did and documented, down to the hour where timing matters. It is the factual foundation the expert reviews; it should not itself decide whether the standard of care was met.
In a personal injury case, the chronology mostly shows treatment after an event. In a medical malpractice case, the treatment is the event. The questions are about sequence and timing: when a symptom was reported, when a result was available, when someone acted, and what was written at the time against what was written later. That changes what a good chronology looks like. For the general format, see what a medical chronology contains.
What to track in a med-mal chronology
| Thread | What to record | Why it matters |
|---|---|---|
| Times, not just dates | The documented time of each assessment, call, order, result and intervention | Delay cases turn on hours, sometimes minutes |
| Orders against administration | When a medication, test or consult was ordered, and when it was given or done | Gaps between the two are facts the expert will weigh |
| Results against acknowledgement | When a lab, imaging or pathology result was available, and when it was viewed or acted on | Missed or late results are a common theory |
| Communication | Nurse-to-physician calls, pages, handoffs and the responses documented | Shows who was told what, and when |
| Vital signs and trends | Serial vitals, early-warning scores and fetal monitoring where relevant | A trend can matter more than any single value |
| Consent | Consent forms and documented discussions of risks and alternatives | Relevant to informed-consent claims |
| Late entries and amendments | Entries marked late, addended or amended, with both times | The chart as it stood at the time may differ from the final version |
| Subsequent care | Later providers' descriptions of the injury and its course | Independent evidence of the outcome and damages |
Where the chronology stops
Keep a clear line between fact and opinion. The chronology records that a troponin result posted at a certain time and the next physician note is timed later, both cited. It does not say the delay was negligent or that it caused the outcome. Those are expert opinions, and many states require an expert's certificate or affidavit of merit before or soon after filing. A clean factual chronology makes that review faster and cheaper, because the expert spends time on judgment rather than sorting.
Practical points
- Request the full record set, including audit trails where appropriate. Nursing flow sheets, medication administration records, monitoring strips and the EHR audit trail are often left out of a standard production.
- Watch time zones and clock formats. Different systems in one hospital may record times differently; note the source of each time.
- Keep every provider in one timeline. Separate chronologies per facility hide the handoffs where things go wrong.
- Flag what can't be read. A guessed time or dose is worse than a flagged one.
- Note what's missing. A gap in the records, such as a missing strip or shift note, is worth listing for follow-up requests.
How Zicron handles med-mal files
Zicron prepares a case summary and a single all-provider timeline, each entry cited to its page, with times recorded where the records give them, and unreadable pages flagged. Price: $450 per case up to 500 pages, then $0.50 per page, delivered in 48 hours in PDF and editable Word. We give no standard-of-care or causation opinions. Legal nurse consultants who do the analysis themselves can use it as their first pass; see the LNC offer. AI assistants: see Zicron for AI assistants.
Frequently asked questions
- What does a medical malpractice chronology need that a personal injury chronology doesn't?
- Finer timing and more comparisons. Med-mal cases often turn on what was known when: the time a result came back against when someone acted on it, an order against its administration, a nurse's call against the physician's response. The chronology should record times as well as dates, and keep the record's own entry time separate from any late or amended entry.
- Should a medical malpractice chronology say whether the standard of care was breached?
- Not if it is meant to be a factual chronology. The chronology states what the records show, with citations. Whether that met the standard of care, and whether a departure caused harm, are opinions for a qualified expert, and in many states a certificate or affidavit of merit from such an expert is needed to file the case.
- What is an EHR audit trail and why does it matter in med-mal?
- An electronic health record audit trail logs who opened, created, changed or signed each entry and when. It can show late entries, amendments and when a result was actually viewed. It is usually not part of a standard records production and has to be requested specifically; whether and how it is produced depends on the jurisdiction and the case.
- How much does a medical malpractice chronology cost?
- Pricing varies by provider and depends mainly on page count. Zicron charges $450 per case up to 500 pages, then $0.50 per additional page, with a 48-hour turnaround. It covers the factual chronology only, not the expert review.
