Disease Prevalence by ICB — NHS QOF Data
Real NHS England Quality and Outcomes Framework (QOF) 2024/25 recorded prevalence of six chronic conditions across all 42 English Integrated Care Boards — plus the Gera Chronic Disease Burden Index.
What is the recorded prevalence of chronic diseases across England by area (ICB)?
According to NHS England's QOF 2024/25 data, 15.23% of eligible patients on English GP registers have recorded hypertension, 14.27% depression and 7.89% diabetes. Gera publishes the figure for all six priority conditions across the 42 English ICBs, re-dated each annual QOF release.
| Condition | England prevalence | Patients on register |
|---|---|---|
| Diabetes | 7.89% | 4,109,134 |
| Hypertension | 15.23% | 9,711,491 |
| Coronary heart disease | 2.98% | 1,899,633 |
| Dementia | 0.78% | 498,887 |
| Asthma | 6.56% | 3,944,639 |
| Depression | 14.27% | 7,317,368 |

NHS disease prevalence data: frequently asked questions
- What is the Gera Chronic Disease Burden Index (GCDBI)?
- The GCDBI is a 0–100 index that summarises an ICB's overall chronic-disease burden from real NHS QOF prevalence data. For each ICB it sums the ratio of the area's prevalence to the England rate across six conditions (diabetes, hypertension, coronary heart disease, dementia, asthma and depression), then maps the median ICB to 50. A higher score means greater population-weighted chronic-disease burden. The England reference equates to 45.3.
- Where does this disease prevalence data come from?
- From NHS England's Quality and Outcomes Framework (QOF) 2024/25 publication — the annual dataset of recorded disease prevalence on every GP practice register in England. Gera aggregates the practice-level prevalence to all 42 Integrated Care Boards. It is open data under the Open Government Licence v3.0.
- Which conditions are covered?
- Six high-priority conditions: diabetes, hypertension, coronary heart disease, dementia, asthma and depression. Each has a national hub page and a page for every one of the 42 English ICBs, with the real recorded prevalence and how it compares to the England average.
- Is QOF prevalence the same as the true number of people with a condition?
- Not exactly. QOF prevalence counts patients with a recorded diagnosis on GP registers, so it can understate conditions that are under-diagnosed and varies with how completely practices code diagnoses. It is, however, the most complete and consistent national source for comparing recorded chronic-disease prevalence between areas.
Worried about a chronic condition?
Recorded prevalence is an area-level statistic, not a personal risk score. A GeraClinic UK-registered clinician can assess your individual risk and arrange tests or referrals — often the same day.
