This video shows what happened after a routine dental checkup identified a mass in a young mother's jaw. She was referred to a specialist who promptly removed it. However, her real problems began after the lab used by the specialist misdiagnosed the mass as an aggressive form of cancer, prompting a battery of needless treatments and a terminal prognosis.
Another such story is that of Isabel Maude; when she was 3 years old, her fever was dismissed as chicken pox complications by her doctor. Only when she collapsed and was rushed to a hospital was it determined that she actually was suffering from toxic shock syndrome and necrotizing fasciitis, a flesh-eating bacteria.
But rather than take legal action, Isabel's father, Jason Maude, developed an online diagnostic aid.
Diagnostic errors have long been a problem of modern medicine. They occur in 10 to 30 percent of cases, and in 5 to 10 percent of all deaths. But with concerns growing about malpractice suits, the Veterans Administration (VA) and Kaiser Permanente are introducing initiatives aimed at correcting most common diagnostic failures, such as not ordering the right tests or failing to perform adequate physical exams.
Kaiser and the VA are using tools such as Web-based "decision support" programs, which help doctors by suggesting an array of possible diagnoses. One such system, known as Isabel, was the one co-created in London by Jason Maude.
