Delay, misdiagnosis & failure to diagnose medical negligence claims

An unintentional delay is when there is sufficient information available, but it is for one reason or another overlooked

If there has been a delay in diagnosis, a misdiagnosis or a failure to diagnose and that failure has resulted in injury, you may be able to make a medical negligent claim for compensation.

See our article on The Process Commencing your Medical Negligence Claim.

What does delay mean?

Example: your test results show that you have cancer but your does not act on the information contained in the test and you suffer as a result of the delay.

What does misdiagnosis mean?

When an incorrect diagnosis was made before the correct diagnosis. Misdiagnosis can occur in one of three ways

  1. Underdiagnosing – when the given diagnosis is less serious than the correct diagnosis
  2. Over diagnosing – when the given diagnosis is worse than the correct diagnosis
  3. Incorrect diagnosing – completely wrong diagnosis

Example: you attend your doctor because you have a persistent sore throat, your doctor performs a check up and tells you that you simply have a sore throat. You like in pain for some years and subsequently find out that you have throat cancer, that is now too advanced for treatment.

How do I prove delay, misdiagnosis or a failure to diagnose?

The first step in establishing your claim for delay, misdiagnosis, or failure to diagnose is to look at the clinical notes.

This is because most diagnostic errors are evident from the treatment provider or medical professions notes.

What we look for:

  • The history taken – is it detailed or brief?
  • Legibility of the notes – if hand written and illegible this could be a source of confusion which leads to error
  • The systems in place – Are they complex and confusing?
  • Shift hand over – Errors or misrepresentations at hand over resulting in a different course of action
  • Lack of definite diagnosis
  • Whether there are any referrals
  • Numerous diagnoses
  • Extensive pathology, radiological or diagnostic testing such as scans
  • Where the notes come from
    • Emergency department
    • Hospitals
    • General practitioner
  • Assessment
  • Plans
  • Follow ups with the patients

How do I win my case?

You will need to prove using evidence that the doctor failed in their duty and had they had exercised due care and skill there would not have been a delay, misdiagnosis or failure to diagnose.

The law surrounding delay, misdiagnosis or failure to diagnose is complicated. For this reason, Garling & Co Lawyers offers a no obligation free case assessment so that you can better understand your rights and the prospect of success in your medical negligence / medical malpractice claim.

I engaged Garling & Co to guide me through a personal injury claim and could not have asked for better representation. Matthew was in a different class to the other lawyers I had spoken to, and that... was clear from our very first phone call. At that time, I was not even sure a claim would go ahead. It was just a call for advice and Matthew was generous with his time which created immediate trust.My options were always explained clearly and the decision was always left with me with no pressure to follow a particular course of action. Allison and the rest of Matthew's team are equally excellent and were on hand throughout, taking me through the process and passing on information at the right time.No hesitation in recommending them to anyone looking for the best advice in NSW.read more

Kerry and her team stepped in, everything changed. They showed me the kind of genuine empathy, warmth, and human kindness that you just don't expect to find in the legal world. They truly, deeply understand the complexities of psychological injury law, but more importantly, they understand the human being behind the case. No matter how scrambled or anxious my mind was feeling, they always found the time to answer my frantic check-ins and left me feeling completely reassured and safe.What I respect most about them is their absolute integrity.Kerry has a brilliant legal mind specialising in personal injury,and only ever sticks strictly to the real facts and let the honest, medical truth do the talking.Thank you Kerry and Myriel.❣️read more
