A delayed diagnosis case involves an injury tied to a failure to recognize a condition within a timeframe when appropriate medical decision-making would have identified it. The “delay” might be measured in days, weeks, months, or longer, and it can happen when a provider misses symptoms, orders the wrong tests, fails to follow up on abnormal results, or misreads imaging or pathology information.
In Wisconsin, these cases often arise from situations where symptoms are real but interpreted too narrowly. A patient may report persistent pain, unusual bleeding, neurological changes, or breathing problems, and the provider may reassure the patient or treat the symptoms without adequately investigating serious possibilities. When the condition is finally identified, it may be at a more advanced stage, requiring more intensive treatment, leaving lasting impairment, or increasing the risk of complications.
Sometimes the delay is not only about recognition. It can involve systems problems that affect care coordination, such as test results not being communicated, referrals not being completed, or follow-up appointments being missed. Even when everyone involved acted in good faith, a lack of reasonable follow-through can still lead to preventable harm.
