A correct and timely diagnosis is the foundation of medical care. When a doctor identifies what is wrong, treatment can begin. When a doctor misses what is wrong, a treatable condition can become a fatal one. Cancer that could have been caught early advances unchecked. A heart attack is sent home as indigestion. A stroke is dismissed as a migraine. Sepsis is missed until a patient is in irreversible decline.
Silver Golub & Teitell (SGT) represents Connecticut patients and families harmed by diagnostic errors, including a recent $49 million jury verdict for a woman whose cervical cancer went undetected for years. If you or a loved one has suffered serious harm because a medical professional failed to diagnose, misdiagnosed, or delayed the diagnosis of a serious condition, a Connecticut diagnosis errors attorney at the firm can help.
A diagnosis error happens when a medical professional fails to identify a patient's condition correctly or in time for treatment to make a difference. Diagnosis errors generally take one of three forms.
- Misdiagnosis occurs when a doctor reaches the wrong conclusion. The patient is told they have one condition when they actually have another. The patient may then receive unnecessary treatment for a condition they do not have, while the real condition continues to progress untreated.
- Failure to diagnose occurs when a medical professional fails to identify the condition at all. The patient is sent home with reassurance, often after symptoms have been attributed to something benign. The underlying condition is not addressed.
- Delayed diagnosis occurs when the correct diagnosis is eventually reached, but only after a window for effective treatment has narrowed or closed. With many conditions, particularly cancers and time-sensitive emergencies, even a delay of weeks or months can change the outcome from recovery to permanent injury or death.
Diagnosis errors arise from a range of failures: a rushed appointment in which the doctor does not take a complete history; a failure to order appropriate diagnostic tests; misinterpretation of imaging or laboratory results; a failure to follow up on abnormal findings; or a failure to refer the patient to a specialist when the situation calls for one. Not every missed diagnosis is malpractice. Medicine is uncertain, and some conditions are genuinely difficult to identify. A diagnosis error rises to the level of malpractice only when a medical professional fails to meet the accepted standard of care and that failure causes harm.
Some conditions are particularly sensitive to diagnostic error, either because their early symptoms can be mistaken for less serious problems or because they progress so quickly that even a short delay changes the outcome. SGT has handled cases involving each of the following:
Sepsis and Other Infections
Sepsis is the body's catastrophic response to infection, and it kills more Americans every year than many widely feared diseases. Its early signs (fever, rapid heart rate, confusion) can be mistaken for ordinary viral illness. Once sepsis progresses, organ failure can follow within hours. A failure to recognize sepsis early, particularly in hospitalized or post-surgical patients, is among the most preventable causes of in-hospital death.
Stroke
Strokes require treatment within a narrow time window. The clot-dissolving drug tPA must generally be administered within hours of symptom onset, and mechanical thrombectomy has its own time-sensitive window. When stroke symptoms (sudden weakness on one side, difficulty speaking, vision changes) are dismissed or misattributed to migraine, anxiety, or intoxication, the chance to prevent permanent brain damage is often lost.
Lung and Other Cancers That Depend on Early Detection
Many cancers are highly treatable when caught early and devastating when caught late. Lung, breast, colon, cervical, and prostate cancers all have well-established screening protocols, and abnormal findings on imaging or laboratory tests demand prompt follow-up. When suspicious findings are not communicated to the patient, not followed up on, or not referred to a specialist, a treatable cancer can advance to a stage at which cure is no longer possible.
Heart Attack
Heart attacks are commonly misdiagnosed in emergency departments, particularly in women, younger patients, and patients whose symptoms do not fit the classic presentation. Atypical symptoms (jaw pain, fatigue, nausea) can be sent home as anxiety or indigestion. Failure to order an EKG, troponin testing, or appropriate imaging in a patient with cardiac symptoms can have fatal consequences.
Severe Blood Clots
Pulmonary embolism and deep vein thrombosis can be lethal, and both can present with symptoms (shortness of breath, calf pain, chest discomfort) that overlap with less serious conditions. Patients at elevated risk, including those who are post-surgical, post-partum, or on certain medications, require heightened vigilance. A failure to consider, evaluate, or rule out a blood clot in a high-risk patient can be catastrophic.
Meningitis
Meningitis can progress from mild illness to permanent neurological injury or death within hours. Its early symptoms (headache, fever, stiff neck) overlap with many less serious conditions, and the diagnostic workup requires lumbar puncture and prompt initiation of antibiotics. Delays in recognizing meningitis, particularly in children, are among the most devastating diagnostic errors a doctor can make.
Encephalitis
Encephalitis, an inflammation of the brain often caused by viral infection, can cause permanent cognitive injury or death if not treated promptly. Early symptoms can mimic psychiatric conditions or ordinary viral illness, and diagnosis requires imaging, lumbar puncture, and a high index of suspicion. Failure to recognize encephalitis and initiate antiviral treatment can leave a patient with lifelong disability.
Proving a diagnosis error claim requires more than showing that a diagnosis was missed. Connecticut law requires the plaintiff to establish four elements: that a doctor-patient relationship existed; that the medical professional failed to meet the accepted standard of care for evaluating the patient's symptoms; that this failure caused the harm; and that the patient suffered measurable damages as a result. The standard of care question turns on what a reasonably competent medical professional in the same field would have done with the same information. That requires expert testimony from a similar healthcare provider. Causation can be especially complex in diagnosis cases because the defense will often argue that the underlying disease, not the missed diagnosis, caused the patient's outcome. Successful cases require a clear demonstration that earlier diagnosis would have changed the result. Connecticut also requires a written opinion from a similar healthcare provider, confirming evidence of medical negligence, to be filed with the complaint. This procedural requirement is strict, and a missing or deficient opinion letter can end a case before it begins.
Diagnostic error cases are among the most complex in medical malpractice litigation. They turn on detailed reconstruction of what the patient reported, what the medical professional saw, what tests were ordered or not ordered, and how findings were communicated and acted upon. The firm has the experience, the medical experts, and the resources to do that work at the highest level. When a Connecticut diagnosis errors attorney at SGT accepts a case, the firm conducts a comprehensive investigation: obtaining the complete medical record, consulting with leading specialists about what should have been done, identifying every provider whose decisions contributed to the outcome, and building a timeline that establishes both negligence and causation.
Connecticut's statute of limitations for medical malpractice, including diagnosis error cases, is two years from the date the injury was discovered, or reasonably should have been discovered, with an absolute outside limit of three years from the date of the negligent act. Different rules can apply when an injury was concealed or when the harm arises from a course of continuing treatment. Diagnosis errors often involve delayed discovery because the patient may not learn that an earlier diagnosis was missed until much later. These deadlines are strict, and the pre-suit opinion letter requirement takes time to satisfy. Families should contact a Connecticut diagnosis errors attorney as soon as they suspect that a diagnostic error has caused serious harm.
Connecticut law allows victims of diagnosis errors to recover both economic and non-economic damages. Economic damages cover quantifiable financial losses: past and future medical expenses, the cost of long-term or lifetime care, lost wages, and lost earning capacity. Non-economic damages compensate for pain and suffering, emotional distress, disfigurement, loss of enjoyment of life, and loss of consortium for spouses and family members. In wrongful-death cases, damages may include the decedent's pain and suffering, loss of enjoyment of life, lost wages and lost earning capacity. Connecticut does not cap compensatory damages in medical malpractice cases.
