Choose a medical chronology when you need to understand what happened and when. Choose a medical record review when you need clinical interpretation of what the records mean for liability, causation, damages, or case strategy. Choose a medical summary when you need a concise overview of the most important medical facts.
These deliverables may rely on the same records, but they serve different litigation tasks.

What Is a Medical Record Review?
A medical record review is a clinical evaluation of the records intended to help an attorney understand the medical issues affecting a claim or defense.
It may address:
- Diagnoses and treatment decisions
- Progression of an injury or condition
- Potential causation issues
- Preexisting conditions
- Treatment gaps
- Conflicting findings
- Medical support for claimed damages
- Missing records or unanswered questions
- Case strengths and weaknesses
Expert Institute’s medical record review process includes record intake and preparation, medical-team analysis, and physician review or consultation when required by the engagement. The resulting work product can help counsel screen a claim, refine a case theory, prepare deposition questions, or identify issues for further expert analysis.
A medical record review is not automatically a formal expert report. Counsel should confirm whether the physician is providing confidential consulting support, a preliminary evaluation, or an opinion intended for litigation use.
Best uses for medical record review
Choose a medical record review when you need to:
- Screen a medical malpractice or personal injury claim
- Evaluate causation or alternative causes
- Understand the effect of preexisting conditions
- Identify clinically significant inconsistencies
- Assess liability or damages issues
- Prepare questions for a physician or expert
- Determine why a diagnosis, test result, or treatment decision matters
Limitations
The review is only as reliable as the records provided. Missing imaging, prior treatment records, operative reports, or follow-up documentation may prevent a reviewer from reaching a supported conclusion.
The reviewer’s specialty should also match the principal medical issues.
What Is a Medical Chronology?
A medical chronology converts the record set into a structured timeline. It allows counsel to follow the sequence of symptoms, diagnoses, treatment, testing, and provider involvement.
A chronology may include:
- Date of service
- Provider and facility
- Reported symptoms
- Diagnoses
- Treatment and procedures
- Medications
- Imaging and laboratory findings
- Referrals and follow-up recommendations
- Page references or hyperlinks
Expert Institute’s Medical Chronologies use AI to process the record set and identify key events, diagnoses, medications, and treatments. The chronology is then reviewed by a medical team for clarity and consistency. Features may include focused issue tracking, hyperlinked page references, and a categorized document index.
A chronology explains what the records document. It does not establish whether a provider met the standard of care or whether an event caused the claimed injury.
Best uses for a medical chronology
Choose a chronology when you need to:
- Reconstruct a long or fragmented treatment history
- Identify the sequence of symptoms and treatment
- Locate records quickly during a deposition
- Compare the documented timeline with testimony
- Prepare a demand letter or mediation submission
- Identify treatment gaps
- Track multiple providers
- Organize records for expert review
A chronology may reveal facts that warrant deeper review. For example, it may show prior similar symptoms, treatment after a later incident, or an absent follow-up record. Determining the medical significance of those facts may require physician analysis.
Limitations
A chronology does not independently determine:
- Standard of care
- Medical causation
- Treatment necessity
- The significance of a treatment gap
- Whether a condition was preexisting or aggravated
- Whether conflicting findings affect liability or damages
What Is a Medical Summary?
A medical summary is a condensed narrative of the facts most relevant to a defined legal task. It does not necessarily list every encounter, and it does not necessarily include physician analysis.
A summary may cover:
- The claimed injury
- Initial presentation and diagnosis
- Major treatment phases
- Surgeries
- Significant imaging or test results
- Prior similar complaints
- Current condition
- Claimed restrictions or prognosis
Because “medical summary” is not a standardized service category, counsel should define the reviewer, scope, level of detail, and whether clinical interpretation is expected.
Best uses for a medical summary
Choose a summary when you need to:
- Orient a new attorney or team member
- Prepare an internal case memo
- Provide a concise mediation overview
- Communicate the treatment history to a client or claims professional
- Reduce a completed chronology to the most important facts
- Present a condition-specific or injury-specific narrative
Limitations
A summary is intentionally selective. It may omit less prominent events that later become important.
It is usually not the best standalone deliverable for evaluating complex causation, testing a detailed timeline, locating source documents during testimony, or analyzing multiple providers.
How Much Clinical Interpretation Does Each Provide?
The main difference is the level of judgment applied to the records.
A chronology answers:
What happened, when, and where is it documented?
A summary answers:
Which medical facts should the reader understand first?
A medical record review answers:
What is the potential medical significance of those facts?
Clinical review may be necessary when a case involves competing causes, preexisting conditions, delayed diagnosis, conflicting imaging, gaps in care, multiple specialties, or disputed damages.
AI can assist with sorting, extraction, indexing, and initial timelines. It does not replace qualified clinical judgment when counsel must determine why a finding matters.
Which Service Should You Choose?
Choose a medical chronology when:
- The records are voluminous or disorganized.
- You need a clear treatment timeline.
- You need page-level source access.
- You are preparing for a deposition, demand, mediation, or expert handoff.
Choose a medical record review when:
- You need physician interpretation.
- Causation, standard of care, preexisting conditions, or damages are disputed.
- You are screening a claim for merit.
- You need to identify medical strengths, weaknesses, or unanswered questions.
Choose a medical summary when:
- You need a concise narrative rather than a complete timeline.
- The audience needs a high-level case overview.
- A chronology or full record review has already been completed.
- The scope and reviewer qualifications are clearly defined.
Use more than one deliverable when:
A complex case may require a chronology first, followed by physician review of disputed issues and a concise summary for mediation, client communication, or internal strategy.
A practical sequence is:
- Organize the records into a chronology.
- Identify disputed events, conditions, or missing documents.
- Submit focused questions for physician review.
- Prepare a concise summary for the intended audience.
Turnaround Factors
Turnaround depends on more than page count.
- For medical record review, key factors include medical complexity, number of specialties, reviewer availability, missing records, requested issues, and consultation needs.
- For chronologies, factors include record volume, scan quality, duplicate files, number of providers, indexing requirements, and requested focus areas.
- For summaries, factors include record length, requested detail, reviewer type, narrative length, and citation requirements.
Clear intake instructions help the reviewer prioritize the facts that matter and reduce unnecessary work.
Get the Right Medical Record Deliverable
Start with a medical chronology when the main challenge is organizing the treatment history. Choose a medical record review when the case requires physician interpretation or strategic evaluation. Use a medical summary when the audience needs a concise narrative of the most important facts.
