What is classed as medical negligence?

If you’ve suffered injury or harm as a direct result of substandard care from a medical professional, this may be classed as medical negligence.

There are many examples of medical negligence, but some of the most common include:

  • Delayed diagnosis or misdiagnosis: This could include a healthcare professional failing to diagnose your condition correctly or in a timely manner, causing the condition to worsen.
  • Surgical errors: Ranging from not following the proper hygiene or sterilisation protocols to operating on the wrong body part.
  • Cancer diagnosis: This could include delayed diagnosis or misdiagnosis of treatment and this in some cases has reduced the chances of a successful outcome.
  • Childbirth injuries: This could include avoidable complications such as fractures during delivery or brain damage caused by oxygen deprivation.
  • Gynaecology and pregnancy negligence: This refers to any substandard care relating to women’s reproductive health, and may include failure to diagnose or treat conditions such as endometriosis, ectopic pregnancies, or ovarian cysts. In pregnancy-related cases, negligence may involve poor monitoring of the mother or baby or failure to detect abnormalities.
  • Orthopaedic negligence: This relates to errors in the diagnosis or treatment of bones, joints, and muscles. It could include missed fractures, incorrect treatment plans, or poorly performed joint replacements.
  • Spinal injuries: Examples include surgical errors during spinal operations, delayed diagnosis of spinal cord compression, or failures to act on symptoms such as numbness or weakness in the spine.
  • Brain injuries: from surgical errors, infections or complications during childbirth to failure to diagnose or treat a stroke promptly.
  • Eye injuries: Examples include misdiagnosis or delayed diagnosis, mistakes during eye surgery that result in infection, worsened vision, or blindness, or failure to diagnose eye conditions leading to preventable vision loss.
  • Fatal accident claims: Fatal medical negligence claims may arise where substandard care, misdiagnosis, surgical errors, or failures to provide timely treatment directly contribute to the loss of life. While no amount of compensation can replace a loved one, a fatal accident claim can help families get justice and financial support following their loss.
