When Needed
This assessment is essential when a claimant alleges that a healthcare provider failed to identify a mental health condition, leading to avoidable harm or incorrect treatment.
What Is a Misdiagnosis Assessment?
A psychological misdiagnosis assessment is a specialised forensic evaluation of the diagnosis, psychological consequences and relevant clinical evidence. A psychologist may address the standard expected of a psychological practitioner where that issue falls within the expert’s competence. Where the alleged misdiagnosis concerns a doctor, prescriber or another professional discipline, an appropriately qualified expert from that discipline is required.
The assessment applies the Bolam test to consider whether the practitioner’s actions would be supported by a responsible body of medical opinion within the relevant specialty. It also considers the Bolitho criteria, assessing whether the clinical opinion relied upon has a logical and defensible basis.
- Breach of duty — failure to meet the standard of a reasonably competent practitioner
- Causation — assessing on the balance of probabilities whether the misdiagnosis caused or materially contributed to the claimant’s injury
- Standard of care — evaluation based on the Bolam and Bolitho principles
- Differential diagnosis — consideration of alternative psychological conditions at the time
- Delayed diagnosis — impact of the time lapse between symptom onset and correct identification
- Avoidable harm — identification of injuries that would not have occurred with a correct diagnosis
Our experts are highly experienced in providing expert witness testimony for the High Court and County Courts. They ensure that every report adheres to CPR Part 35 requirements, providing an impartial and robust analysis of the clinical facts.
The assessment integrates a thorough review of medical records, psychological history, and current clinical presentation to form a definitive expert opinion. This evidence assists the court in determining whether any clinical negligence resulted in injury, including where relevant issues of loss of chance.
