According to a John Hopkins University School of Medicine study, the majority of medical malpractice claims comes about because of a failure to diagnose, or because of a misdiagnosis. The headline grabbing stories of sponges being left inside of a patient or the wrong body parts being amputated are actually rarities. Yet a wrong diagnosis is as potentially damaging as any medical mistake.
The study concluded that diagnosing errors resulted in the most cost and most harm to patients. It is estimated that these diagnosis errors affect anywhere between 80,000 to 180,000 patients every year. And failures to diagnose a health issue appear to be a much more serious problem than even a misdiagnosis.
