Medical Malpractice Case Evaluation Checklist for Attorneys

By John Mahoney · April 2026 · 14 min read

Medical malpractice cases are among the most expensive and time-intensive matters a plaintiff firm can take. Average litigation costs range from $100,000 to $500,000 per case before trial, case timelines stretch 2 to 4 years, and the national plaintiff success rate hovers around 20 to 30 percent. Accepting the wrong case does not just waste your time — it bleeds your firm financially for years.

That is why a disciplined, repeatable case evaluation process matters more in medical malpractice than in almost any other practice area. The attorneys who consistently win are not the ones who take every case that walks in the door. They are the ones who screen methodically, decline strategically, and commit resources only to cases with genuine merit and recoverable damages.

This checklist covers every phase of the medical malpractice case evaluation process, from initial intake call through the decision to accept or decline. Use it as a framework to standardize your screening and avoid the costly mistakes that sink plaintiff firms.

Phase 1: Initial Intake Screening

The first phase happens before you review a single medical record. It is a 15 to 30 minute phone screening designed to identify obvious disqualifiers and determine whether the case warrants further investigation.

Statute of limitations check

This is the first question, every time. Medical malpractice statutes of limitations vary dramatically by state, ranging from 1 year in Kentucky and Louisiana to 6 years in Maine. Most states fall in the 2 to 3 year range, but discovery rules, minor tolling provisions, and continuing treatment doctrines create complexity that requires careful analysis.

• Date of alleged malpractice: When did the incident occur?
• Date of discovery: When did the patient first know (or reasonably should have known) about the injury?
• Applicable state statute: Which state's law governs, and what is the filing deadline?
• Tolling provisions: Is the patient a minor? Was there fraudulent concealment? Does a continuing treatment doctrine apply?
• Certificate of merit deadline: Many states require a certificate of merit from a qualified expert within 60 to 90 days of filing. Factor this into your timeline.

If the statute has expired and no tolling argument is viable, the case is over regardless of its merits. Do not proceed to further evaluation.

Basic fact pattern assessment

During the initial call, gather enough information to determine whether the fact pattern plausibly supports a malpractice claim. You are not making a final determination — you are screening for obvious viability.

• What medical treatment was received? Surgery, diagnosis, medication, monitoring, emergency care?
• What went wrong? In the patient's own words, what happened that should not have?
• What injury resulted? Physical harm, additional treatment needed, permanent impairment, death?
• Who provided the care? Physician name, specialty, hospital or facility name
• Has the patient seen another doctor who confirmed something went wrong? A subsequent treating physician's opinion is often the first indicator of merit.

Red flags that suggest a strong case

Certain fact patterns correlate strongly with meritorious claims. When you hear these during intake, the case warrants deeper investigation.

• Wrong-site surgery or retained surgical instruments: These are res ipsa loquitur cases where negligence is self-evident.
• Delayed cancer diagnosis with interval progression: Patient had symptoms, diagnostic testing was not ordered or was misread, cancer progressed from treatable to terminal.
• Failure to act on abnormal test results: Lab work or imaging showed a critical finding that was never communicated to the patient or followed up on.
• Medication errors: Wrong drug, wrong dose, known allergy administered, dangerous drug interactions with documented contraindications.
• Failure to monitor during and after procedures: Anesthesia complications, post-surgical hemorrhage, or other complications that went undetected due to inadequate monitoring.
• Informed consent failures with resulting injury: Patient was not told about a material risk that actually materialized.
• Significant deviation from clinical guidelines: Treatment clearly inconsistent with published standards of care for the specialty.

Phase 2: Medical Records Collection and Review

If the case passes initial screening, the next step is obtaining and reviewing the medical records. This is where most of the work happens — and where most screening failures occur when the review is incomplete or rushed.

Records you must obtain

A thorough evaluation requires records from every provider involved in the patient's care during the relevant time period. Missing a single facility can mean missing the critical evidence.

• Hospital records: Admission notes, discharge summaries, operative reports, anesthesia records, nursing notes, medication administration records, physician orders, lab results, imaging reports, consultation notes, and incident reports (if obtainable)
• Primary care records: Office visit notes, referral letters, test orders and results, medication lists for at least 2 years before and after the incident
• Specialist records: All treating specialists during the relevant period, including consultation reports and treatment plans
• Emergency department records: Triage notes, ED physician notes, radiology reads, transfer documentation
• Imaging and pathology: Actual films and slides if possible, not just written reports — your expert may need to review the raw data
• Pharmacy records: Dispensing history that can corroborate or contradict the medical record
• EMS and ambulance records: If applicable, these capture the patient's condition at a critical moment
• Prior medical history: Enough history to establish the patient's baseline health and rule out preexisting conditions that defense will raise

What to look for in the records

When reviewing records — whether manually or with AI assistance — you are looking for evidence that supports or undermines each element of the malpractice claim: duty, breach, causation, and damages.

• Standard of care deviations: Documentation that shows what was done (or not done) and how it differs from accepted medical practice
• Timeline inconsistencies: Gaps in documentation, records that were clearly created after the fact, or timestamps that do not align with the clinical narrative
• Communication failures: Abnormal results that were never followed up, referrals that were never made, handoff errors between providers or shifts
• Documentation alterations: Late entries, amended records, or notes that contradict contemporaneous documentation from other providers
• Nursing notes vs. physician notes: Discrepancies between what nursing staff documented and what the physician recorded — nursing notes are often more detailed and contemporaneous
• Prior complaints or incidents: Any indication that the provider or facility had prior knowledge of similar problems

Building the chronological timeline

A complete medical chronology is the backbone of your case evaluation. It lays out every significant clinical event in order, making it possible to identify the exact moments where the standard of care was breached and where earlier intervention could have changed the outcome.

For a complex malpractice case, building this timeline manually takes 20 to 40 hours. The records are often thousands of pages from multiple facilities, in different formats, with overlapping and conflicting information. This is the single most time-consuming step in case evaluation, and it is where AI tools deliver the most value — reducing timeline construction from days to minutes while maintaining the detail your experts need.

Phase 3: The Four Elements Assessment

Every medical malpractice claim requires proof of four elements. Your case evaluation must assess the strength of evidence for each one, because weakness in any single element can be fatal to the case.

1. Duty of care

Was there a physician-patient relationship? In most cases this element is straightforward — the patient was treated at the facility by the provider in question. It becomes complicated in situations involving on-call physicians who never saw the patient, radiologists who read imaging remotely, consulting physicians whose recommendations were not followed, and emergency department coverage arrangements.

Document the evidence establishing the relationship. If duty is contested, you need records or testimony establishing that the provider assumed responsibility for the patient's care.

2. Breach of the standard of care

This is where medical expertise becomes essential. The standard of care is what a reasonably competent provider in the same specialty, under the same or similar circumstances, would have done. Establishing breach requires showing that the defendant's conduct fell below that standard.

Key questions for your evaluation:

• What did the provider do or fail to do?
• What would a competent provider in the same specialty have done differently?
• Are there published clinical guidelines, practice standards, or hospital protocols that support the alleged breach?
• Is there documentation in the record itself (such as a subsequent treating physician's notes) that suggests the care was substandard?
• Can you identify a qualified expert in the same specialty who would testify that the standard of care was breached?

3. Causation

Causation is the element that kills more medical malpractice cases than any other. Even if the provider clearly breached the standard of care, the plaintiff must prove that the breach caused the injury. This requires demonstrating both cause-in-fact (but-for the breach, the injury would not have occurred) and proximate cause (the injury was a foreseeable consequence of the breach).

The causation analysis must account for the patient's preexisting conditions, the natural progression of their disease, and alternative explanations for the outcome. Defense experts will argue that the outcome was inevitable regardless of the alleged negligence. Your evaluation must assess whether your causation theory can withstand that challenge.

4. Damages

Without significant damages, a medical malpractice case is not economically viable regardless of how clear the liability is. Your evaluation must realistically assess both the nature and magnitude of damages.

Phase 4: Expert Witness Consultation

No medical malpractice case moves forward without a qualified expert who will testify that the standard of care was breached and that the breach caused the injury. Your case evaluation is incomplete until you have consulted with an expert.

When to consult an expert

Consult an expert after you have reviewed the records and identified what you believe to be the standard of care violation. Do not ask an expert to do your initial screening — that wastes their time and yours. Come to the consultation with a specific theory: the provider did X, should have done Y, and the failure caused Z. Let the expert confirm, refine, or reject that theory based on the clinical evidence.

Qualifications your expert needs

• Same specialty as the defendant: In most jurisdictions, the expert must practice in the same specialty. A family medicine physician cannot testify about neurosurgery standards.
• Board certification: Not legally required everywhere, but practically essential for credibility
• Active clinical practice: An expert who has not seen patients in 10 years will be attacked on cross-examination. Look for experts who maintain at least part-time clinical practice.
• Licensing in the same or similar state: Some states require the expert to be licensed in the state where the malpractice occurred. Even where not required, it strengthens credibility.
• Teaching or publication history: Academic credentials help but are not required. What matters is that the expert can clearly explain the standard of care to a jury.
• Trial experience: Has the expert testified before? For both plaintiff and defense? A balanced testimony history is more credible than an expert who only works for one side.

What to get from the expert consultation

Your initial expert consultation should produce clear answers to three questions. First, was the standard of care breached? The expert should identify specifically what the provider did wrong and what should have been done instead. Second, did the breach cause the injury? The expert should explain the causal mechanism and address any alternative explanations. Third, is this a case the expert would be willing to testify in? Not every case they think has merit is one they will commit to supporting through deposition and trial.

Phase 5: Cost-Benefit Analysis

Even a meritorious case may not be economically viable for your firm. Medical malpractice litigation is expensive, and the cost-benefit analysis must be realistic.

Estimated litigation costs

Build a budget before you accept the case. Typical cost categories include:

• Medical records acquisition: $500 to $5,000 depending on the number of providers and volume of records
• Expert witness fees: $5,000 to $25,000 for initial review and report, $3,000 to $10,000 per day for deposition, $5,000 to $15,000 per day for trial testimony
• Filing fees and court costs: $500 to $2,000
• Deposition costs: $2,000 to $5,000 per deposition (court reporter, videographer, transcript)
• Demonstrative exhibits and trial preparation: $5,000 to $50,000 depending on complexity
• Life care planner (if applicable): $5,000 to $15,000
• Economist (if lost wages or future damages): $5,000 to $15,000
• Litigation finance costs: If you are financing case costs, factor in the cost of capital

Total estimated range: $25,000 to $150,000 for a case that goes to trial. Complex cases involving multiple defendants, extensive discovery, or novel medical issues can exceed $300,000 in costs.

Realistic damage valuation

Estimate the likely recovery range based on the jurisdiction, the type of injury, and comparable verdicts and settlements. Then apply these filters:

• Damage caps: Does the jurisdiction cap non-economic damages? Many states cap at $250,000 to $750,000, which can make otherwise strong cases uneconomical.
• Comparative fault: Is the patient partially at fault (non-compliance with treatment, delayed follow-up)? Reduce the expected recovery accordingly.
• Collectibility: Can the defendant actually pay a judgment? Individual physician coverage limits, hospital indemnification, and sovereign immunity for government hospitals all affect collectibility.
• Settlement probability: What percentage of similar cases settle, and at what discount to trial value? Most medical malpractice cases that survive summary judgment settle for 40 to 70 percent of estimated trial value.

The accept/decline decision framework

After completing your cost-benefit analysis, apply this framework:

Accept the case if:

• All four elements are supported by evidence in the medical records
• A qualified expert has confirmed breach and causation
• Estimated damages exceed $250,000 (the minimum threshold for most plaintiff firms given litigation costs)
• Expected recovery after costs and fees exceeds 3x your estimated investment
• The statute of limitations provides adequate time to prepare
• The client is credible, cooperative, and has realistic expectations

Decline the case if:

• Causation is speculative or cannot survive defense expert challenge
• Damages are modest relative to the cost of litigation (under $100,000 in most jurisdictions)
• The statute of limitations is expired or critically short without a viable tolling argument
• No qualified expert supports the liability theory
• The patient's non-compliance or preexisting conditions create substantial comparative fault
• The case depends on a novel legal theory with no precedent in the jurisdiction
• The client has unrealistic expectations and is unwilling to listen to realistic assessments

Phase 6: Documentation and File Organization

Whether you accept or decline the case, document your evaluation thoroughly. For accepted cases, this documentation becomes the foundation of your litigation file. For declined cases, it protects you against future claims that you failed to properly evaluate the matter.

For accepted cases, your file should contain:

• Complete medical records from all relevant providers, organized chronologically
• Medical chronology or timeline with page-level citations to the source records
• Expert review letter or preliminary opinion
• Cost-benefit analysis with litigation budget
• Statute of limitations analysis with key dates
• Liability theory summary (breach, causation, damages)
• Witness list (fact witnesses and anticipated experts)
• Client intake questionnaire and signed retainer agreement
• HIPAA authorization for medical records

For declined cases, document:

• Date of initial contact and screening
• Reason for declination (statute issues, insufficient damages, weak causation, etc.)
• Declination letter sent to the potential client with recommendation to seek other counsel
• Any applicable statute of limitations warnings included in the declination letter

Common Case Evaluation Mistakes

After evaluating thousands of potential medical malpractice cases, experienced plaintiff attorneys consistently identify the same recurring mistakes that lead to accepting bad cases or declining good ones.

Mistake 1: Confusing a bad outcome with malpractice

Medicine involves inherent risks. A patient who dies during heart surgery did not necessarily receive negligent care. Your evaluation must distinguish between a bad outcome from competent care and a bad outcome caused by substandard care. This distinction is the core of the case and requires expert analysis, not just sympathy for the patient.

Mistake 2: Incomplete records review

Reviewing only the hospital records and missing the primary care records that show the patient reported symptoms 6 months earlier. Reviewing only the physician notes and missing the nursing documentation that tells a different story. An incomplete records review produces an incomplete evaluation. Get everything before making a decision.

Mistake 3: Ignoring the client as a witness

The client will likely need to testify. Evaluate them as a witness during your intake process. Are they credible? Can they articulate what happened? Are they sympathetic? A strong case with an unsympathetic or incredible client is a problem at trial. This does not mean you decline — but it affects your realistic valuation.

Mistake 4: Underestimating defense resources

Hospitals and insurance companies defend medical malpractice cases aggressively. They hire top defense firms, retain well-credentialed experts, and will outspend you if the case goes to trial. Your evaluation must account for the reality that the defense will mount a vigorous, well-funded challenge to every element of your case.

Mistake 5: Anchoring on the initial theory

Your initial theory of liability may change as you review records and consult with experts. Stay open to the possibility that the real malpractice is different from what the client described, or that the strongest theory involves a different defendant than originally identified. The records tell the story — let them.

Using Technology to Streamline Case Evaluation

The case evaluation process described above is thorough but time-intensive. The records review phase alone can take 20 to 40 hours per case, and most plaintiff firms evaluate 5 to 10 potential cases for every one they accept. That means your firm may spend 100 to 400 hours per month on case evaluation alone — the vast majority on cases you will ultimately decline.

AI-powered medical records review tools can compress the records review phase from days to hours. They extract diagnoses, medications, procedures, and provider information from uploaded records, build chronological timelines, and identify gaps and inconsistencies — all with page-level citations back to the source documents. This does not replace your legal judgment or your expert's medical opinion. It gives you the organized data you need to make those judgments faster and with more confidence.

The practical impact is that you can evaluate more cases in less time, identify the strong cases earlier, decline the weak ones sooner, and allocate your firm's resources more efficiently. For a plaintiff firm that takes medical malpractice cases on contingency, faster and more accurate screening directly improves profitability.
