A misdiagnosis can change the entire trajectory of a person’s medical care. When a Delaware physician identifies the wrong condition, fails to identify a condition, or delays a correct diagnosis, the patient may receive harmful treatment, no treatment, or treatment so late that the underlying condition has progressed beyond what it would have been with a timely answer. In Delaware, misdiagnosis claims fall under the Medical Negligence Act at 18 Del. C. § 6801 et seq., and they are among the most technically demanding cases in personal injury law.
Schuster Jachetti LLP represents Delaware patients and families harmed by diagnostic errors at hospitals, urgent care centers, primary care offices, and specialty practices across the state. Joseph M. Jachetti, Delaware Bar #003744, has handled medical negligence and serious injury matters for over 25 years, and the firm works with qualified medical professionals to evaluate whether the standard of care was breached and whether that breach caused the harm.
If you suspect that you or a family member was misdiagnosed at a Delaware facility, the time to investigate is now. Delaware law imposes strict deadlines on these claims, and records, witnesses, and imaging studies become harder to gather as time passes.
How Misdiagnosis Cases Happen in Delaware
Misdiagnosis can occur in any setting where medical decisions are made. In Delaware, common scenarios include emergency room patients sent home from ChristianaCare, Bayhealth, Beebe Healthcare, TidalHealth Nanticoke, or Saint Francis Hospital in Wilmington with conditions later found to be cardiac events, strokes, pulmonary embolisms, or surgical abdomens. Primary care offices may attribute serious symptoms to anxiety or musculoskeletal causes. Radiologists may miss findings on imaging. Pathologists may misread biopsy specimens.
Wrong diagnosis, missed diagnosis, and delayed diagnosis are all forms of the same underlying claim type — diagnostic error. The legal question is whether a reasonably qualified provider, presented with the same information, would have reached a different conclusion or ordered different testing, and whether that failure caused harm.
Common Conditions Involved in Misdiagnosis Cases
- Cancer (breast, colon, lung, prostate, melanoma) — see also delayed diagnosis cases
- Heart attack and acute coronary syndrome
- Stroke and transient ischemic attack
- Pulmonary embolism and deep vein thrombosis
- Sepsis and severe infection
- Appendicitis and surgical abdominal conditions
- Meningitis
- Ectopic pregnancy
- Diabetic ketoacidosis
- Spinal cord compression — see spinal cord injury
Who May Be Liable
Liability in a Delaware misdiagnosis case can extend to the treating physician, the hospital or facility under respondeat superior, an employer practice group, a radiology or pathology group reading studies remotely, and in some cases a manufacturer of a diagnostic device or test that performed below specifications. Determining the right defendants requires careful review of the medical records and the corporate structure of the providers involved.
How Delaware Law Applies to Misdiagnosis Cases
Delaware misdiagnosis claims are governed by:
- 18 Del. C. § 6801 et seq. — the Delaware Medical Negligence Act
- 18 Del. C. § 6853 — affidavit of merit requirement, which mandates that a qualified medical professional sign an affidavit at the time of filing stating there are reasonable grounds to believe negligence occurred
- 18 Del. C. § 6856 — two-year statute of limitations from the date of injury, with a three-year statute of repose that can bar claims even when the injury was not discovered
- 10 Del. C. § 8132 — modified comparative negligence rule (barred only above 50% fault, i.e., a 51 percent bar)
The affidavit of merit is a hard threshold. Without a qualified medical professional willing to sign, the case cannot move forward. Schuster Jachetti LLP works with qualified medical reviewers to evaluate the records before filing.
Damages You May Be Able to Pursue
- Past and future medical expenses
- Lost wages and lost earning capacity
- Pain and suffering — see what is pain and suffering in Delaware
- Loss of enjoyment of life
- Disfigurement and scarring
- Loss of consortium for a spouse
- Wrongful death damages where applicable
Specific case values depend on the facts, the available insurance, and the strength of the evidence. The firm does not promise specific amounts.
Why Misdiagnosis Cases Are Different From Other Injury Claims
A misdiagnosis case is not a slip-and-fall and is not a car crash. The mechanism of harm is a decision — a clinical judgment that should have been made differently. That makes the case turn on records, on the standard of care at the time, and on what a reasonable physician with the same information would have done. Schuster Jachetti LLP approaches these cases by building the timeline first and then asking what should have happened at each decision point.
Delaware has a structured pre-suit framework for medical malpractice claims. The affidavit of merit requirement at 18 Del. C. § 6853 means that no case can be filed without a qualified medical professional first reviewing the records and concluding there are reasonable grounds. That step protects both physicians and patients — it screens out unsupportable claims and gives genuine claims a basis to move forward.
What the Records Show in a Misdiagnosis Case
The medical record is the centerpiece of the case. Office notes, hospital charts, lab results, imaging reports, and consult notes are reviewed against the clinical presentation. The firm looks for the documented complaint, the documented exam, the differential diagnosis considered, the workup ordered, the results, and the disposition. Gaps in any of these — symptoms not addressed, abnormal results not acted on, a differential that omits a likely cause — can support a claim of breach.
The Causation Question
Even when a misdiagnosis is clear, the patient must show that the misdiagnosis caused the harm. If the correct diagnosis would not have changed the treatment or the outcome, the case may not move forward. Qualified medical professionals address this by comparing the actual course of the disease against what would have been expected with timely diagnosis. In cancer cases this often means comparing actual stage at eventual diagnosis against what the stage would have been months earlier.
How Delaware Hospitals Handle Diagnostic Workups
Larger Delaware health systems follow standardized protocols for common high-risk presentations — chest pain, abdominal pain, headache, shortness of breath. When workup deviates from those protocols without documented clinical reason, that deviation can support a breach claim. Smaller offices and urgent care centers may have less structured protocols, which raises different questions about the reasonableness of the workup performed.
Working With Qualified Medical Professionals
Schuster Jachetti LLP works with qualified medical professionals across multiple specialties when reviewing potential misdiagnosis cases. The medical professional must be qualified to opine on the standard of care for the type of provider being evaluated. A radiologist evaluates the radiology standard. An emergency physician evaluates the emergency medicine standard. A primary care physician evaluates the primary care standard. The choice of medical reviewer can influence whether a case has a realistic foundation.
The Pre-Suit Investigation
Before any complaint is filed, the firm conducts a thorough investigation. That includes ordering complete medical records from every provider involved in the patient’s care during the relevant period — not just the records from the provider whose care is at issue. It includes obtaining imaging studies on disk, lab results, and any pathology specimens that may need re-review. It includes interviewing the patient and family to construct a detailed timeline. Only after this work is complete can a meaningful evaluation of the merits be made.
What to Bring to Your First Consultation
Patients consulting with the firm about a possible misdiagnosis case can help the evaluation by bringing whatever records they already have, a written timeline of the symptoms and visits, the names and contact information of all providers involved, copies of any communications with the providers (including patient portal messages), and any imaging on disk. The firm will request whatever additional records are needed, but a starting point of organized information accelerates the review.
The Significance of Discovery in Misdiagnosis Cases
If the case proceeds to litigation, the discovery phase often reveals information not visible in the medical records alone. Depositions of the providers, internal communications, peer review materials (subject to privilege limits), and policy documents can all become available. The firm prepares for discovery by mapping the providers, the chain of decisions, and the questions that need answers.
Working With Schuster Jachetti LLP on a Misdiagnosis Case
From the first call, the firm’s process is structured to evaluate the case efficiently. Initial intake gathers basic facts. If preliminary review suggests a viable case, medical records are ordered from every relevant provider. Once the records arrive, qualified medical professionals review them. If the medical professional concludes there are reasonable grounds, the affidavit of merit is prepared and the case is filed within the statutory deadline. Throughout, the firm maintains contact with the client about the status and next steps.
Common Misconceptions About Misdiagnosis Claims
Several misconceptions surface repeatedly in initial consultations. The first is that any wrong diagnosis equals malpractice. It does not — the question is whether the diagnostic reasoning departed from the standard of care, not whether the diagnosis turned out to be wrong in retrospect. The second is that the patient must have been injured by treatment to have a claim. They do not — failure to diagnose can be the harm, when timely diagnosis would have led to better outcomes. The third is that physicians cover for each other and no medical professional will testify. In practice, qualified medical professionals do review and sign affidavits when warranted.
The Costs of Pursuing a Misdiagnosis Case
Medical malpractice cases are among the most expensive personal injury cases to pursue. Medical record costs, qualified medical professional fees, deposition transcript costs, and other expenses can run into significant sums before trial. The firm’s contingency fee arrangement means clients do not pay these costs out of pocket; the firm advances them and is reimbursed from any recovery. More on contingency fees.
