What Is a Medication Adverse Effects Assessment?

This assessment involves a comprehensive forensic review to determine if a patient has suffered psychiatric or physical harm due to adverse drug reactions. Our experts evaluate whether the prescribing clinician adhered to the standard of care and if the foreseeable risks were appropriately managed.

The evaluation focuses on causation, assessing on the balance of probabilities whether the medication caused or materially contributed to the subsequent clinical presentation. We assess the application of professional guidelines, such as NICE guidance or the Maudsley Prescribing Guidelines, to identify potential breaches of duty.

  • Standard of care — adherence to recognised prescribing protocols and guidelines
  • Causation analysis — assessing on the balance of probabilities whether drug administration caused or materially contributed to the injury
  • Informed consent — adequacy of risk disclosure prior to the commencement of treatment
  • Monitoring protocols — sufficiency of physical and psychiatric follow-up assessments
  • Differential diagnosis — ruling out underlying or pre-existing psychiatric pathology
  • Condition and prognosis — evaluating the long-term impact and future care requirements

Experts must possess deep knowledge of psychopharmacology and the specific legal tests governing clinical negligence in the UK. Their role is to provide the court with an objective, independent opinion on complex pharmacological interactions and professional standards.

Evidence is gathered through meticulous medical record review and clinical interview. The expert opinion focuses on whether the harm was a result of substandard clinical practice or an unavoidable idiosyncratic reaction.

Key Assessment Components

Our assessment evaluates the following areas:

Prescribing Review

Analysis of the initial indication and dosage against relevant clinical standards and BNF guidance.

Risk Assessment

Evaluation of whether patient-specific risk factors and contraindications were considered before prescribing.

Informed Consent

Examination of whether the patient was warned of material risks and significant side effects.

Clinical Monitoring

Review of whether physical health monitoring and blood tests were performed as clinically required.

Causation Nexus

Determining whether, on the balance of probabilities, the adverse event caused or materially contributed to the claimant’s psychiatric injury.

Impact Assessment

Assessing the extent of the psychiatric injury and identifying any necessary future treatment or rehabilitation needs.
