How to Write an Effective Letter of Instruction

A medicolegal report is only as focused as the questions that generate it. Vague instructions such as “please assess the worker and provide your opinion” leave the expert guessing which issues matter for the claim. Targeted questions on diagnosis, causation, capacity, treatment and prognosis produce reports that decision-makers can actually use.

The letter of instruction also sets ethical boundaries. Experts are asked for independent opinions, not advocacy. Framing questions neutrally, providing balanced records and avoiding pressure to reach a preferred conclusion all support a report that will withstand scrutiny.

Start with the parties, the claim or reference number, the scheme and the purpose of the assessment. Provide a short chronology of the injury, key treatments and current work status. Then list numbered questions. Numbering makes it easier for the expert to answer systematically and easier for you to find the answers later.

Attach the documents the expert needs: treating reports, imaging, operative notes, previous medicolegal opinions and relevant claim correspondence. Flag any missing records you know about. If an interpreter or accessibility arrangement is required for an examinee attendance, say so in the referral as well as in the letter.

One frequent mistake is asking too many overlapping questions that invite repetition. Another is burying the real issue in a long narrative without a clear ask. Equally unhelpful is providing hundreds of pages without highlighting the essential materials. Experts can read a large brief, but a short index of key documents saves time and improves accuracy.

Do not assume the expert knows local scheme thresholds or procedural history unless you state them. If you need comment on a particular guideline edition, name it. If prior opinions exist, ask the expert to address points of agreement and disagreement rather than rewriting the entire history from scratch.

After the letter is ready, the referral process matches the matter to an available specialist with the right expertise. Early discussion with the coordination team can confirm specialty, format, location and likely turnaround. If the report is needed urgently, say so at the outset so an express pathway can be considered where appropriate.

A reliable letter of instruction often follows a simple structure: matter details, short factual summary, list of enclosed documents, numbered questions, and any administrative notes such as interpreter needs or hearing dates. Keep the factual summary short enough that the expert can see the issues quickly, then let the enclosed records carry the detail. If there are contested facts, say so plainly rather than presenting only one side's narrative as settled truth.

Numbered questions work best when each question can be answered without depending on another question's wording. For example, separate diagnosis from causation, and separate current capacity from future treatment needs. Where permanent impairment is sought, identify the body systems or psychiatric domains to be assessed and name the applicable guide. Where capacity is in issue, describe the pre-injury duties or attach a position description so the opinion is grounded in real work demands.

Finally, review the letter once from the expert's perspective. Would a specialist who has never seen the file understand what decision the report must support? If the answer is no, tighten the questions and prune the document list to the materials that matter. A concise, well-organised brief almost always produces a clearer report than a long, unstructured one.
