See the 60-second demo →Diagnostic error is the largest source of serious malpractice harm — the "Big Three" categories (vascular events, infections, cancers) account for roughly three-quarters of serious misdiagnosis harm, an estimated ~795,000 Americans a year suffering death or permanent disability (Newman-Toker et al., BMJ Quality & Safety, 2023–2024). The emergencies below are textbook "cannot-miss" diagnoses — narrow treatment windows where a delay maps directly to harm, which is exactly why a missed one so often becomes a viable case.
Why it's missed
Abdominal pain is one of the highest-volume complaints in medicine, and most of it is benign — the trap. Appendicitis is missed when it doesn't follow the textbook (classic migration of pain to the right lower quadrant). It is missed disproportionately in young children, the elderly, and pregnant patients, where the presentation is atypical and the consequences of delay — perforation, abscess, sepsis — are severe.
What the standard of care generally expects
For abdominal pain that could be appendicitis, the defensible approach generally includes a thorough exam, appropriate labs, and imaging (ultrasound or CT) where the picture is unclear — plus, when discharged without a firm alternative diagnosis, explicit return precautions and a short-interval recheck. Discharging a child with "gastroenteritis" and a rising white count, no imaging, and no follow-up plan is a recurring fact pattern. [Confirm the standard with an expert.]
What makes the case viable
- Breach: a presentation that warranted imaging/observation, with a record showing neither happened.
- Causation: a window in which timely diagnosis would have meant a routine appendectomy instead of perforation, sepsis, and prolonged morbidity.
- Damages: sepsis, multiple surgeries, long-term complications — often in a child.
The records angle
Pull the exam findings, lab values and trends, any imaging (or the lack of it), the discharge instructions, and the timeline across visits. The gap between presentation and diagnosis — documented in the chronology — is the spine of the case.
Screen the case before you spend on workup
Paste the facts into the free Case Merit Score — it weighs the standard-of-care violation, causation, and damages and gives a defensibility read in minutes. Then see how an EHR-built chronology surfaces the timeline and any post-hoc amendments.
