Condition & Prognosis Reports

We can usually see the patient in an outpatient consultation and prepare a Condition and Prognosis report within seven days.  Mr Osman can see the patient in his rooms in Sheffield or Rotherham.

Preliminary Case Assessments (PCAs)

PCAs include a detailed chronology, case summary and expert opinion. They are designed to allow solicitors not only to assess the merits of a medical negligence claim but also to obtain after-the-event insurance. They are unsuitable for disclosure to the other party. However, once a positive PCA has been prepared and subsequently a full report requested, the cost of the PCA will be deducted from the final fee.

Causation and Liability Reports

A detailed Liability and Causation report for medical negligence cases is prepared to fully comply with Part 35 CPR and is suitable for disclosure. We undertake to return a report within 4 weeks of receipt of instruction and the records in hardcopy or electronic format.

Fee structures available on request.
