The Tariff Cliff Edges
Under the current whiplash tariff, compensation is divided into recovery bands. A claimant expected to recover within three months receives one award, while a claimant expected to recover just beyond three months moves into the next tariff bracket.
This creates what clinicians sometimes refer to as “prognostic thresholds.” A patient whose symptoms are likely to resolve in twelve weeks may attract significantly less compensation than a patient whose symptoms are expected to persist for fourteen weeks, despite the injuries being clinically very similar.
The same pattern continues throughout the tariff structure. Moving from a prognosis of nine months to just over twelve months can increase compensation by hundreds of pounds. Extending beyond eighteen months can increase awards by well over a thousand pounds.
Why Accurate Prognosis Matters
Medical experts do not determine compensation. Our role is to provide an independent opinion on diagnosis, causation, and likely recovery.
Nevertheless, the financial consequences of our prognosis mean that accuracy is essential.
An overly optimistic prognosis may undervalue a claimant’s injury. An excessively cautious prognosis may overstate the duration of symptoms. Neither serves the interests of justice.
The challenge is that prognosis is not an exact science. Recovery from whiplash is influenced by multiple factors, including age, previous neck problems, psychological response to the collision, treatment compliance, occupational demands, and pre-existing degenerative changes.
Two patients with apparently identical injuries may recover at very different rates.
The Problem with Calendar-Based Recovery
One criticism of the tariff system is that it converts a complex medical recovery process into fixed time bands.
In clinical practice, recovery is rarely linear. Patients often improve rapidly during the first few weeks, plateau for a period, and then make further progress. Symptoms can fluctuate significantly.
A patient who reports occasional stiffness at six months may technically still be symptomatic, but their functional limitations may be minimal. Conversely, another patient with a shorter overall prognosis may experience severe disruption during the early stages of recovery.
The tariff system cannot fully capture these nuances.
The Importance of Evidence-Based Prognosis
A credible prognosis should be based on more than the claimant’s expectations.
Medical experts consider:
The mechanism of injury.
The severity and distribution of symptoms.
Examination findings.
Response to treatment.
Time elapsed since the accident.
Relevant medical history.
Current functional limitations.
A prognosis should reflect the balance of probabilities based on the available evidence, not the compensation consequences that may follow.
Looking Beyond the Numbers
Compensation tariffs inevitably focus attention on recovery duration because duration is easy to measure and standardise.
Yet from a medical perspective, recovery is about much more than time alone. The quality of recovery, return to normal activities, psychological adjustment, and restoration of function are often more important indicators of outcome than the precise month in which symptoms finally resolve.
As clinicians, our responsibility remains unchanged. We must provide an objective assessment of likely recovery, regardless of whether the prognosis places a claimant just below or just above a particular tariff threshold.
The legal system may value months. Medicine must continue to value patients.
