Misdiagnosis in US: 795,000 Affected Annually

Misdiagnosis Crisis in the US: 795,000 Affected Annually,

A startling study conducted by Johns Hopkins Armstrong Institute Centre for Diagnosis Excellence reveals that as many as 795,000 Americans die or suffer lifelong disabilities each year due to misdiagnoses. The report sheds light on the alarming public health crisis caused by diagnostic errors, with strokes being identified as the most commonly misdiagnosed disease in the US.

The Extent of Misdiagnosis

The study estimates that approximately 371,000 patients’ lose their lives, and an additional 424,000 are left permanently disabled due to incorrect diagnoses by healthcare workers. This finding has brought attention to the under-resourced public health emergency of diagnostic errors.


Doctors in the US misdiagnose patients with the wrong disease at least 11% of the time. While some diseases are accurately identified, others face misdiagnosis rates of more than 50%, notably rare conditions like spinal abscesses.


Strokes top the list as the most commonly misdiagnosed condition, with a misdiagnosis rate of 17.5%. The study highlights that patients presenting with symptoms of dizziness and vertigo often end up misdiagnosed with an inner ear disease, delaying proper stroke treatment.

The findings of this study underscore the urgent need for improved diagnostic resources and investment in healthcare to address the critical issue of medical misdiagnosis in the US. Raising awareness and enhancing diagnostic accuracy are crucial steps towards preventing avoidable deaths and lifelong disabilities caused by diagnostic errors.


  • Improved communication between healthcare providers. Healthcare providers need to be better at communicating with each other about their patients’ care. This will help to ensure that all of the relevant information is considered when making a diagnosis.
  • More emphasis on the patient’s overall health history. Healthcare providers need to take the time to consider the patient’s overall health history when making a diagnosis. This information can be essential for making an accurate diagnosis.
  • Use of more advanced diagnostic tools. There are a number of new diagnostic tools that are becoming available. These tools can help to improve the accuracy of diagnosis.
  • Training for healthcare providers. Healthcare providers need to be better trained in how to avoid misdiagnosis. This training should include information on how to communicate effectively with each other, how to consider the patient’s overall health history, and how to use advanced diagnostic tools.
