Seven dimensions, each scored 1-5 and summed to a total out of 35. It is a triage and communication tool to compare problems - not a measure of truth. How it is derived is set out in The Method.
The problem
The NHS is configured overwhelmingly to treat illness once it has occurred, and only marginally to prevent it. Demand on the acute system rises relentlessly as a result, while the public-health and preventive spending that would reduce that demand is small, and has been cut. The service is, in effect, structurally bound to a model that guarantees its own overload.
The evidence
The elective waiting list stood at roughly 7.1m pathways in early 2026, with only about 62% of patients treated within 18 weeks against a 92% standard. Meanwhile the public health grant - the main route for preventive spending - is around £3.6bn, only about 2.2% of the NHS England budget, and has fallen by roughly a quarter per person in real terms over the decade to 2025/26. Successive reform plans have prioritised acute funding; independent analysts judged the 2025 spending settlement disappointing for prevention.
Why the market fails
Prevention is largely a public good - clean air, vaccination programmes, public-health surveillance, and obesity and smoking policy benefit everyone non-excludably and are under-provided by markets. It is also a capital-horizon mismatch: the returns to prevention accrue over decades, well beyond any private - or political - investment horizon. And much ill health is driven by externalities in the food, alcohol and built environment.
Why it has persisted
Prevention loses every budget round to treatment, because the cost of cutting prevention is invisible and deferred while the cost of an overloaded A&E is visible and immediate. Repeated structural reorganisation substitutes for the harder strategic shift. The payoff horizon for prevention is longer than an electoral cycle, so the rational political move is to fund the visible crisis.
Who bears the cost
Patients who wait, and who fall ill with preventable conditions; the working-age economy, through avoidable ill health; and future taxpayers, who fund an ever-larger acute system.
Policy direction - outline only
Proposed mechanism
A protected, growing prevention budget set as a defined and rising share of total health spending; multi-year settlements so preventive programmes are not cut in-year; and a small number of high-evidence preventive priorities - obesity, smoking, early diagnosis, vaccination - with hard targets.
Must resolve
The legal mechanism that prevents the ring-fence being overridden in a crisis; the workforce shift; and the metrics.
Main risks
The cost of double-running both models during transition; political pressure to raid the ring-fence; preventive interventions that sound good but lack strong evidence.
