Inaccurate diagnoses of a medical condition negatively impact medical treatment and how well a patient responds to medical care. A study by researchers from Johns Hopkins University, and reported by the National Institutes of Health (NIH), showed that diagnosis errors account for more than a third of malpractice claim settlements and cause likely preventable injury or death for up to 160,000 patients each year. Often there are warning signs of the negligence that led to misdiagnosis, such as lack of clear communication between doctors, misinterpretation of test results, or failure to recognize the seriousness of health issues that patients have raised– in fact, more than half of misdiagnosis errors involve the ordering of diagnostic tests or the taking of patient history information.

Statistics show that pneumonia, congestive heart failure, kidney failure and cancer are among the medical conditions most frequently misdiagnosed, and the consequences can be frightening:

  • 38% of misdiagnosis incidents cause considerable harm
  • 35% result in very serious harm or permanent damage
  • 14% mean immediate or inevitable death

When misdiagnosis results in physical pain, emotional distress or death because a health problem was overlooked or improperly addressed, lawyers with the experience found at WMK are skilled at identifying the legal distinctions mean our clients are entitled to compensation.
