What Is a Breach & Causation Assessment?
A Breach & Causation assessment is a specialized forensic evaluation designed to assist the court in clinical negligence claims involving mental health care. It involves a two-stage process: determining if the medical professional’s actions fell below the accepted standard of care (breach) and whether this failure directly resulted in a documented psychiatric injury (causation).
Our experts apply the Bolam test to evaluate whether the clinician acted in accordance with a responsible body of medical opinion, as refined by the Bolitho requirement, which requires that such professional opinion be capable of withstanding logical analysis.
- Standard of Care — establishing the level of care expected from a reasonably competent psychiatric professional
- Breach of Duty — identifying specific instances where care fell below the required professional standard
- Factual Causation — applying the ‘but for’ test to determine if the harm would have occurred anyway
- Legal Causation — assessing whether the breach was a material cause or a significant contributory factor
- Psychiatric Diagnosis — formal identification of injury using ICD-11 or DSM-5 diagnostic criteria
- Remoteness of Damage — evaluating if the specific psychiatric harm was a foreseeable consequence of the breach.
The assessment requires a highly experienced expert witness who understands both the clinical complexities of mental health treatment and the legal framework of tort law.
We provide a clear nexus between the evidence found in contemporaneous records and the claimant’s current clinical presentation to offer an objective opinion on liability.
Key Assessment Components
Our assessment evaluates the following areas:
Record Analysis
A meticulous review of medical records to establish a clear chronology of care and identify any deviations from accepted professional standards.
Clinical Interview
A face-to-face or remote psychiatric examination to assess the claimant’s current mental state and history.
Breach Evaluation
Establishing causation requires demonstrating, on the balance of probabilities, that the psychiatric injury would not have occurred ‘but for’ the identified breach of duty, or that the breach made a material contribution to the harm where legally applicable.
Causation Mapping
Establishing the causal link between the identified breach and the development or exacerbation of psychiatric symptoms.
Vulnerability Assessment
Distinguishing between the impact of the breach and any pre-existing conditions or constitutional vulnerabilities.
Prognostic Opinion
Outlining the long-term impact of the psychiatric harm and the likely response to future treatment.
