Medical Record Review for Expert Witnesses: A 5-Phase Guide
Kalivar
10/25/2026
Medical record review for expert witnesses is a structured, neutral process: you inventory the chart, rebuild the timeline, judge each key decision against what was known at the time, and flag what is missing. Done well, it is the foundation of every report, deposition and trial opinion you will give. This guide walks through a five-phase method, a spreadsheet template you can copy, and the traps that catch even experienced clinicians.
Key takeaways
- Treat every chart as if you do not know which side retained you. Impartiality starts with the first page.
- Work in five phases: orientation, document inventory, timeline reconstruction, focused clinical analysis, and gap identification.
- Judge each decision by what the clinician knew at that moment, not by the outcome you now know.
- Keep your notes separate from the originals, cite pages precisely, and date every draft and chronology.
- A chronology with columns for date, time, document reference, document type, quoted text and comments lets you defend your reasoning years later.
- Ask for missing records through the attorney before you reach a conclusion.
Why does medical record review matter so much for an expert witness?
Your opinion is only as strong as the record behind it. In Inside the Expert Witness World, Michael Kalivar describes record review as the foundation for reports, depositions and testimony. It is where you identify the relevant facts, build a clear timeline, decide whether care met accepted standards, and detect gaps or inconsistencies.
It is also where your credibility is won or lost. Opposing counsel will test what you read and whether your conclusions follow from the documents.

What are the five phases of an expert witness record review?
Phase 1: Initial orientation
Start with the referral letter or the attorney's summary. Use it for background, but do not let it anchor you. A summary reflects one side's framing, and your job is to form your own view from the source documents.
Then clarify the exact questions you are being asked. Is the issue a delay in diagnosis, a surgical error, or informed consent? Write the questions down, and list any additional records you will need.
Phase 2: Document inventory
Log every record you receive before you read any of it in depth. Note what arrived, from whom, and on what date. Flag anything that appears to be missing, such as a consult referenced in a nursing note but absent from the file. Organize the set chronologically.
If you are deposed, you can then state exactly what you reviewed and when.
Phase 3: Timeline reconstruction
Build the sequence of events and cross-check dates and times across documents. A triage time in the emergency department record should agree with the first nursing entry. When it does not, note the discrepancy.
Mark the turning points: consults, test results, and decision junctures. These become the anchors for your analysis.
Phase 4: Focused clinical analysis
For each pivotal event, ask three questions:
- What was known at that time?
- What was decided?
- Did that decision align with accepted standards of care?
Stay inside the moment. Do not use information the clinician did not have. This is where the standard of care and causation concepts from our overview of the expert role come into practice.
Phase 5: Identifying gaps
List what is missing, ambiguous or contradictory. Request the missing material through the attorney before you conclude anything. An opinion built on an incomplete record invites a challenge you could have avoided.
Which record types should you read, and what should you look for?
Different documents answer different questions. The table below summarizes what to pull from each.
| Record type | What to look for |
|---|---|
| Emergency department records | Triage times, handoffs, consult requests |
| Operative reports | Indication, findings, complications, post-operative plan |
| Nursing notes | Vital sign trends, medication administration times, symptoms |
| Consult notes | Timeliness, and how critical findings were communicated |
| Laboratory and imaging | Time the result was available versus time it was acknowledged and acted on |
| EHR access logs | When providers viewed results, which is crucial in delay-of-diagnosis cases |
The gap between when a result existed and when someone acted on it is often the heart of a delay case. Access logs can show whether a result was viewed, and when.
What pitfalls undermine a record review?
Four biases come up again and again.
- Anchoring bias. You form an early opinion from part of the record and then read everything else to fit it.
- Incomplete context. You look at one provider and miss system or communication problems around them.
- Retrospective bias. You judge a decision using information that was not available when it was made.
- Overinterpretation. You infer something that is not documented.
A simple defense is to separate what the chart says from what you think it means.
Watch for copy-paste in the EHR
Electronic records make it easy to carry text forward. The book gives two examples: a wrong medication dose that was repeated for days after it had been corrected in practice, and a "patient improving" statement that was copied forward after the patient had actually worsened.
Learn to tell active assessment from propagated text. This matters most when testimony hinges on what clinicians "knew or should have known." A note that merely repeats yesterday's note is weak evidence of what anyone knew today.
How do you take notes and protect confidentiality?
Good habits here protect both the case and you.
- Keep your notes separate from the original records. Never annotate source documents.
- Cite precisely, using page numbers, exhibit labels or Bates stamps.
- Store everything on encrypted devices.
- Date your drafts and chronologies so you have version control.
Avoid speculative or casual remarks in your notes. They may be discoverable, and a joking comment can look very different when read aloud in court. Stay neutral until the review is complete.
What does a good chronology look like? A template you can copy
The author shares his own method in the book. He digitizes paper records to PDF, after asking the attorney before shredding any originals. He stores the PDFs in a dedicated cloud folder with subfolders by date received, and labels multiple files A, B, C.
His notes live in a spreadsheet. A reference such as "A4" means page 4 of document A. Here is a table template you can copy into your own spreadsheet:
| Date | Time | Document reference | Document type | Quoted text | Comments |
|---|---|---|---|---|---|
| 10/02/2025 | 14:05 | B12 | RN note | "BP 82/48, patient diaphoretic" | Hypotension documented; relevant to timing of notification |
| 10/02/2025 | 14:45 | B13 | RN note | "Surgeon notified by phone" | Interval of 40 minutes from prior entry |
| 10/03/2025 | 09:10 | C3 | ICU consult | "Recommend return to OR" | Consult timing; compare to imaging time |
The columns work like this:
- Date and Time. The moment the event happened or was documented.
- Document reference. The file letter and page number, so anyone can find the source.
- Document type. Pathology, RN note, ICU consult, and so on.
- Quoted text. Copied directly from the record, with no paraphrasing.
- Comments. Why it matters. The author sometimes color-codes this column to show which side an event may support.
This format lets you reconstruct your reasoning years later. It is also transparent and defensible under cross-examination, because every entry points back to the source.
How do you write a preliminary summary?
Keep it a neutral, factual timeline. For example: "At 14:05, nursing note documents hypotension; surgeon notified at 14:45." State facts and cite them. Keep facts separate from analysis.
End with questions or points for clarification, not conclusions. You are not yet ready to conclude, and a written summary may be read by people other than the attorney.
How can you review records more efficiently and ethically?
Block out dedicated review time and log your hours for billing. Skim the whole record first, then return for a deep, targeted read. Tag key pages and build summary tables as you go.
AI tools can help draft timelines from large record sets. Always verify their output against the originals. They are no substitute for your clinical judgment.
On ethics, the same rule applies to any summary you did not write yourself. Verify attorney-prepared or AI-prepared summaries against the source documents. Stay neutral until you are done, and decline cases outside your scope.
Frequently asked questions
How long does a medical record review take?
It depends on the size of the chart and the number of questions asked. A single-admission case may take a few hours, while a complex multi-provider case can take much longer. Logging your time as you work gives you accurate billing and a realistic estimate for the next case.
Should I read the attorney's case summary first?
Read it for background, but do not rely on it. Phase 1 of the method uses the summary only to understand the questions being asked. Your conclusions should come from the source records, and you should check any summary against the originals.
What should I do if records are missing?
Do not guess. List what is missing and request it through the attorney before you form a conclusion. If the records never arrive, say so plainly in your analysis and describe how the gap limits what you can opine on.
Can I write notes directly on the medical records?
No. Keep your notes in a separate document and never annotate source documents. Cite pages, exhibit labels or Bates stamps so that anyone can match your notes to the original.

If you would like a low-effort way to get a feel for medical-legal work, see how Kalivar works for physicians. Experts review brief, anonymized case summaries in their own specialty, on their own schedule. There are no medical records to review at this stage, and an opinion form takes about 10 to 20 minutes. Experts are paid for the opinions attorneys reward, and an introduction can lead to retained expert witness work. Your identity is shared only if you accept an introduction after declaring no conflict of interest, and you can decline any introduction.
