How a Medical Review Is Organized

A medical opinion is only as reliable as the path from the records to the conclusion. This is that path, set out in advance so counsel can test it before relying on it.

The six stages

  1. Scope and relationships. Identify the parties, organizations, clinical setting, dates, forum, deadlines and requested opinions; screen conflicts; and decide whether the question fits Dr. Gill's qualifications and capacity. A preliminary case assessment, an organizational consultation and a testifying engagement require different materials and produce different work, so the role is fixed here.
  2. Materials and completeness. Agree how records will be transferred and catalogued. Log each source received, its version and identifier. Identify material gaps early: a selected extract may answer a narrow question and be useless for a broader one, and the absence of a medication administration record, a routing log or an outside report can change everything.
  3. Chronology and clinical context. Build a source-linked chronology that separates, wherever the evidence allows, the time an event occurred, the time it was documented, when information became available, when it was communicated, when receipt can be established, and when someone responded. Reconstruct the clinical picture at each decision point: what the patient presented with, what was known, what reasonably should have been sought, and what options existed in that setting.
  4. Standards and competing explanations. Identify the clinical sources in effect at the time — guidelines, standards, regulations, accreditation editions, policies — and explain what each one does and does not establish. Test the concern under review against the evidence that supports it, the evidence that weakens it and the reasonable alternative accounts, including the account most favorable to the other side.
  5. Findings and limits. State what can be concluded, what cannot, and why. Keep three questions analytically separate: whether the documentation is adequate, whether the clinical care was appropriate, and whether any shortfall caused harm. Identify questions that need another discipline. Express uncertainty in words, not invented numbers.
  6. Additional evidence. When new material arrives — a deposition, a newly produced record, an audit report — reassess the opinion against it. Record substantive revisions and the reasons for them.

Practices that make the method defensible

Pinpoint citation

Every factual statement in a chronology or report cites the record page, Bates number or identifier it comes from, so a reader can check it in seconds.

Optional blind first read

On request, the first chart review is done before Dr. Gill hears the retaining party's theory and, where feasible, without outcome information. The approach is documented.

Standards of the time

Clinical sources are applied in the version in effect when the care occurred, and the version is named. Hindsight is identified and set aside.

Adverse evidence on the page

Every written opinion includes the evidence against it and explains why the opinion holds anyway — or does not.

Breach and causation kept apart

A documentation problem is not proof of poor care, and poor care is not proof of harm. Each link is analyzed on its own evidence, and causation questions that need a specialist are flagged.

Human verification

No conclusion or citation rests on software. If any tool is used to organize records, its use is agreed in advance and every output is checked against the source.

How the method is organized around the rules on expert evidence

The method is organized around what courts ask of expert testimony. Federal Rule of Evidence 702 requires the proponent to show, more likely than not, that the opinion rests on sufficient facts or data, is the product of reliable principles and methods, and reflects a reliable application of those methods to the facts; the 2023 committee note adds that each opinion must stay within what the method can support and cautions forensic experts against claims of absolute certainty (Rule 702). In California, an expert's opinion must rest on matter of a type an expert may reasonably rely upon, the court may examine the reasons for it, and speculative opinion or reasoning unsupported by the material relied on is excluded (Evidence Code §801, §802; Sargon).

Stages two and three address the sufficiency question. Stage four supplies the method and its sources. Stage five keeps each conclusion inside the limits of the evidence. Stage six keeps the opinion honest as the record grows. The physician ethics that govern testimony — accurate qualifications, independent evaluation, recent and substantive experience, and the standards in effect at the time of the event — run through all six (AMA Opinion 9.7.1).

The report

A written report is matched to the engagement and to the requirements of the proceeding. It ordinarily identifies the assignment, the qualifications relevant to it, the materials considered and those missing, the factual chronology, the medical questions, the sources and method, each opinion with its reasoning, adverse evidence, causal limits and material assumptions, and the evidence that would change the opinion. Factual observations and inferences are labeled as such. Federal retained-expert reports must also list publications from the previous ten years, testimony from the previous four years and the compensation to be paid (FRCP 26(a)(2)(B)); those lists are maintained from the start.

See the work samples for fictional examples of a chronology, an opinion-and-evidence matrix, an AI-documentation comparison and a missing-records request.

What the method cannot do

It does not authenticate documents, extract or validate EHR audit data, determine credibility, decide legal questions or guarantee admissibility. It does not reach a conclusion the records cannot support. When those limits matter, the report says so and identifies who can help.

Questions counsel often ask

Can the initial review be done without knowing our theory of the case?

Yes. On request, Dr. Gill can perform the first chart review before he is told the retaining party's theory, and where feasible without outcome information, documenting the approach in the file. A review that reaches its own view of the decision points first is harder to attack as reverse-engineered.

Which standards are applied — today's or those at the time of care?

Those in effect at the time of the events. Guidelines, accreditation editions, regulations and policies change; a 2026 standard is not applied to a 2021 decision. The report identifies which version of each source was used and why it applies to the setting and date at issue.

Is this method a validated scientific instrument?

No. It is an organized professional method built from ordinary clinical reasoning and the requirements that govern expert evidence. Its worksheets are organizational tools, not scoring systems. Its reliability comes from transparency: every step can be traced to the records and explained.

Have a matter that may fit?

Send a short, non-clinical inquiry naming the parties, forum, dates and question. Conflicts are screened before any records are sent, and every party is offered the same method and terms.

This page describes professional consulting services for attorneys and healthcare organizations. It is not legal advice or medical advice. An inquiry does not create an engagement, an attorney–client relationship or a physician–patient relationship. Opinions are formed only after review of the evidence and may support, limit or contradict the position of the party that requests them. Fees are never contingent on the content of an opinion or the outcome of a matter.
