Report scope
What this report is for
An addendum report addresses a material development after the original opinion: new records, examination findings, treatment, a changed prognosis or a question that could not previously be answered. It should identify exactly what has changed and whether the original conclusion is affected.
The precise remit, documents and assumptions should be settled in the letter of instruction. An expert’s opinion is confined to their own discipline and the material provided.
Instruction requirements
A focused route to usable evidence
The original author is often best placed to address the development. Where a new discipline or question is needed, the instruction should say so expressly.
Defined questions
Identify the issues the report is asked to address.
Relevant records
Provide the material needed to form a properly bounded opinion.
Transparent assumptions
Separate facts assumed for the purpose of the report from clinical findings.
Independent opinion
The expert’s duty and the applicable procedural rules remain central.
Use the register to identify a suitable discipline, then agree the scope directly.
