A misdiagnosis case generally arises when a healthcare provider fails to identify a condition correctly or fails to recognize warning signs that should have triggered additional testing, referral, or timely treatment. The error may be a “wrong answer,” a missed diagnosis, or a delay that allowed a treatable problem to progress. In Hawaii, these cases often include situations where patients received care in urgent settings, primary care offices, emergency departments, or specialty clinics with varying access to imaging and subspecialty review.
The key legal question is not simply whether the outcome was bad. Instead, the focus is whether the care fell below the accepted standard expected of a reasonably careful provider in similar circumstances and whether that lapse contributed to the harm. Even when a provider acted in good faith, the law evaluates whether the clinical process was reasonable based on what was known at the time.
