MedCo reforms and the whiplash tariff have made symptom duration a central issue. Prognosis affects valuation, settlement strategy and whether the medical evidence is accepted or challenged. A difference of several months can materially alter the way a claim is handled.
The difficulty is that improving the process does not remove the need for clinical judgement. It makes the quality of that judgement more visible.
Why prognosis matters.
Whiplash is commonly diagnosed from the history and examination rather than definitive imaging. There may be no fracture, dislocation or structural abnormality. The expert must therefore assess the accident mechanism, symptom onset, examination findings, medical records and recovery pattern.
The prognosis then becomes central. When did symptoms begin? Are they ongoing? Is the duration consistent with the records and history? Were there previous neck problems? Was treatment delayed? Did the claimant return to work? Were there psychological symptoms?
These are not administrative details. They are the substance of the opinion.
Prognosis should not be a number selected from habit. Three, six, nine and twelve months appear so frequently that they can begin to resemble standard categories rather than individual conclusions.
A prognosis should arise from the evidence, not custom.
Consistency is not standardisation.
Low-value whiplash work creates pressure for reports to be quick and predictable. Many cases share familiar features: a rear-end collision, neck pain, physiotherapy and gradual recovery. But familiar cases are not identical.
One claimant may recover quickly. Another may have pre-existing cervical symptoms, travel anxiety or a physically demanding job. Another may describe symptoms that are not supported by the records or examination.
The expert should explain why the individual claimant falls within an expected recovery range or why their case differs. Applying the same prognosis repeatedly is not efficiency. It is a failure to analyse the evidence.
MedCo improved the route, not the reasoning.
A report obtained through the correct system can still be weak. Accreditation, fixed costs and procedural compliance do not guarantee sound causation analysis or a properly reasoned prognosis.
The first report often directs the whole claim. If the prognosis is too generous, the claim may be overvalued. If it is too restrictive, the claimant may be undercompensated. If the reasoning is thin, both sides are left disputing a conclusion that was never adequately explained.
The records remain essential.
The expert should consider when symptoms began, whether medical attention was sought, what treatment followed, whether complaints were consistent and whether there was a previous history of neck pain, accidents or degeneration.
A claimant who reported symptoms promptly and recovered gradually after treatment presents a different picture from someone who first reported significant symptoms weeks later. A claimant with active symptoms before the accident presents another picture again.
Delay in treatment does not automatically defeat a claim. Some people wait to see whether symptoms settle, and minor symptoms may develop over several days. Nevertheless, the absence of an early complaint must be considered, as must any inconsistency between the later account and the records.
The tariff sharpened the dispute.
The whiplash tariff places direct emphasis on symptom duration, turning prognosis into a major valuation driver.
That creates legitimate pressure from both sides. Claimants want the full recovery period recognised. Defendants want duration tested. Experts may be asked why symptoms persisted beyond an expected period or why a shorter prognosis is justified despite ongoing complaints.
A prognosis should not be extended merely because pain is still reported, nor shortened because the collision appears minor. The question is whether the symptoms and recovery period are medically plausible when considered against the accident circumstances, examination, records, treatment and pre-existing history.
Where symptoms continue, the report should explain what is expected to happen and why. Where recovery has occurred, it should identify a reasonable date or range if the evidence allows. Where uncertainty remains, the expert should say so.
Psychological symptoms require care.
Whiplash claims may also involve travel anxiety, sleep disturbance, low mood, irritability or reduced confidence.
A GP or orthopaedic expert may record those symptoms and comment within their competence. They should not give firm psychiatric opinions unless qualified. Where psychological symptoms materially affect prognosis, function or valuation, specialist evidence may be required.
What a good prognosis should show.
A good whiplash report should identify the injury, symptom onset, treatment history, pre-accident baseline, examination findings and current function. It should then explain why the proposed recovery period is appropriate.
If the claimant has recovered, the report should explain how that conclusion was reached. If symptoms persist, it should address why they persist, whether the duration is consistent with the evidence and what further recovery is expected. Where there were prior symptoms, the expert should distinguish the background condition from any accident-related aggravation.
The strongest reports are not necessarily the longest. They are the clearest. They show that the expert has reviewed the records, tested the history and considered alternative explanations.
The reform still needed.
Too many reports still treat prognosis as a routine final paragraph rather than the central opinion. Too many disputes arise because the report gives a duration without explaining the reasoning.
Whiplash claims may be low in value, but the medical evidence remains important. For the claimant, it may determine whether symptoms are recognised. For the defendant, it may determine whether a claim is paid or challenged. For the court, it may be the only clinical evidence available.
A prognosis is not a guess dressed as medical opinion. It is a clinical judgement that must be connected to the evidence.
MedCo can support independence, accreditation and structure. The expert must still provide the reasoning.
