When Needed

What Is a Psychological Treatment Errors Assessment?

This assessment provides a rigorous forensic evaluation of whether a healthcare provider’s actions fell below the reasonable standard of care expected in the psychological field. It identifies specific instances of clinical negligence within the context of diagnosis, medication management, and therapeutic interventions.

The evaluation applies the Bolam test and Bolitho criteria to determine if the clinician’s decisions were supported by a responsible body of medical opinion and whether that opinion withstands logical analysis by the court.

  • Breach of Duty — determining if the care provided was below an acceptable professional standard
  • Causation — establishing, on the balance of probabilities, a causal link between the alleged error and the patient’s harm
  • Diagnostic Error — failure to correctly identify a mental health condition leading to inappropriate care
  • Medication Mismanagement — errors in prescribing, dosing, or monitoring pharmacological interventions
  • Risk Assessment Failure — inadequate evaluation of suicide, self-harm, or violence towards others
  • Inadequate Supervision — failure to provide appropriate observation levels or secure environment controls

Our specialist psychological experts provide clear, objective analysis for the court, ensuring all reports remain compliant with Civil Procedure Rules and current clinical guidelines.

We synthesise the totality of evidence, including medical records and claimant interviews, to deliver an independent expert opinion on breach, causation, and prognosis.

Key Assessment Components

Our assessment evaluates the following areas:

Clinical Record Review

A meticulous analysis of the medical history and treatment logs to identify deviations from standard practice.

Psychological Examination

A direct assessment of the claimant to determine the nature and extent of the psychological injury sustained.

Standard of Care Analysis

Evaluating clinician actions against NICE guidelines and the British Psychological Society’ professional standards.

Causation Mapping

Establishing whether the psychological injury would have occurred “but for” the alleged treatment error, or whether the error made a material contribution to the injury where legally applicable.

Prognosis Assessment

Providing an expert view on the future recovery and ongoing treatment needs of the claimant.

Quantum Evaluation

Assessing the impact of the alleged error on the claimant’s functional capacity and ongoing psychological prognosis.
