Cross-check a medical report against the records

Okafor v Northmere Distribution LtdEmployer’s liability · left wrist fractureFictional

The situation

Daniel Okafor, a 41-year-old warehouse operative, slipped on a wet loading-bay ramp at work on 11 March 2026 and fractured his left wrist. Our orthopaedic expert examined him on 2 October 2026 and the report arrived on 9 October. It has not been served. Before it goes to the client for checking and then to the other side, the fee earner wants it checked line by line against the records.

Why it matters

Errors in a medical report become credibility points once the report is served, and the defendant will have the GP records too. A factual correction now costs a letter. The same point raised in cross-examination can cost the claim.

D3Client’s draft witness statement (extract)Daniel Okafor · taken 25 September 2026

I am left-handed. I write and do most things with my left hand.

I was off work completely for eight weeks. I then went back on light duties for four weeks, mainly scanning and labelling, before going back to my full duties on 3 June 2026.

I hurt the same wrist playing football in 2023, but it cleared up within a few weeks and I had no problems with it after that.

My wrist still aches when it is cold and after a long shift.

Why this prompt works

The rule is supplied

The PD 35 requirements are written into the prompt, so the tool checks the report against the rule rather than its memory of it.

Three kinds of discrepancy

Separating factual errors, omissions and internal inconsistencies tells the fee earner which points are for the expert and which the client must confirm.

A hard line on opinion

The guardrail keeps the letter within what an instructing party may properly ask of an expert.

Both accounts recorded

The tool is told not to prefer the client’s version over the records, or the records over the client.

What a good answer catches. The dominant hand (contradicted within the report itself), the accident year, the 2023 sprain to the same wrist, the return-to-work history, hospital records apparently unread and an incomplete PD 35 declaration.

A. Discrepancy table

#	Report says	Source says	Type	Why it matters
1	Right-hand dominant [D1 §3.1]	Left-handed [D3 ¶4]. The report also refers to the ‘left (dominant) side’ [D1 §6.1]	FACTUAL ERROR INTERNAL INCONSISTENCY	Dominance affects the functional impact of a left wrist fracture.
2	Accident on 11 March 2025 [D1 §3.4]	11 March 2026 [D2 12/03/2026] [D4]	FACTUAL ERROR	The prognosis period runs from the accident date.
3	No previous upper limb injury [D1 §4.2]	Left wrist sprain on 17/08/2023, settled by 07/09/2023 [D2]; confirmed by the client [D3 ¶12]	OMISSION	Same wrist. The defendant will see these records.
4	Normal duties six weeks after the accident [D1 §5.3]	Unfit for work 12/03 to 06/05/2026, then amended duties for four weeks [D2]; full duties from 3 June 2026 [D3 ¶9]	FACTUAL ERROR	Affects the loss of earnings claim and the recovery history.
5	Records reviewed: GP records only [D1 §2.1]	A&E and fracture clinic records were sent [D4]	OMISSION	The treatment history may rest on the client’s memory rather than the hospital notes.

C. Draft letter to the expert

Daniel Okafor: accident on 11 March 2026. Your report dated 9 October 2026

Dear Mr Wrenfield

Thank you for your report. Before it is disclosed, please consider the points below. They concern factual accuracy and clarity only. We do not ask you to change your opinion, and you should amend the report only as you consider appropriate.

1. Hand dominance. Paragraph 3.1 records Mr Okafor as right-hand dominant, while paragraph 6.1 refers to his left side as dominant. Mr Okafor tells us he is left-handed. Please confirm the position.

2. Accident date. Paragraph 3.4 gives 11 March 2025. The records give 11 March 2026.

3. Previous history. The GP records show an attendance on 17 August 2023 for a left wrist sprain, recorded as settled on 7 September 2023. Please say whether you have considered this entry and whether it affects your opinion on causation or prognosis.

4. Time off work. Paragraph 5.3 records a return to normal duties at six weeks. The fit notes indicate Mr Okafor was unfit for work until 6 May 2026 and then on amended duties for four weeks. Please clarify the history and whether it affects your opinion.

5. Records reviewed. Our letter of 4 September 2026 enclosed the A&E and fracture clinic records. Paragraph 2.1 lists the GP records only. Please confirm whether you reviewed the hospital records.

6. Declaration. Please consider whether paragraph 9 should include the statement required by paragraph 3.2(9)(b) of Practice Direction 35.

Yours sincerely

D. Points to confirm with the client

Hand dominance for writing, tools and sport.
The 2023 football injury: any treatment or symptoms after September 2023.
Exact dates off work and on light duties, with payslips for March to June 2026.
What he told Mr Wrenfield about his return to work at the examination.
Any physiotherapy or other treatment since June 2026.

Could not verify. Whether the hospital records were actually received by the expert: D4 shows they were sent, not that they arrived.

Before you rely on it

Check the discrepancies yourself against the full records. GP records are long and coded, and a tool working from an extract will miss entries it never saw.
Keep every request within accuracy, completeness and clarity. The opinion must remain the expert’s own; never suggest a different conclusion.
If the report came from the other side’s expert or a single joint expert, use written questions under CPR 35.6 instead: proportionate, put once, within 28 days of service of the report, and for clarification only unless the court permits or the other party agrees.
Send the factual points to the client to approve before the letter goes to the expert.
Medical records are special category personal data under UK GDPR. Use only a tool your firm has approved for health data.

Where tools go wrong

Quietly correcting the date or the dominant hand in its summary instead of flagging the error.
Suggesting what the prognosis ‘should’ be.
Treating a missing statement as compliant because nothing contradicts it.

Adapt it

For a report served by the defendant, change step 4 to ‘draft CPR 35.6 questions’ and add the 28-day deadline, calculated from the date of service, to the output.
Add the schedule of loss as a further source and ask the tool to check that the report supports each head of loss claimed.
