Regional data are available in this report

Figures released today by NHS Digital1 provide information on the prevalence of 21 conditions2, including asthma, hypertension, dementia, diabetes, and depression.

The annual report, Quality and Outcomes Framework (QOF) - Prevalence, Achievements and Exceptions Report, England 2016-17 also identifies how the prevalence of these conditions has changed since the previous year.

Prevalence data on these conditions can be broken down sub-nationally to regional and general practice level.

This robust dataset is made up of information voluntarily provided by 95.4 per cent of general practices in England. It is collected through the QOF, which is primarily used to improve the care patients receive by rewarding practices for the quality of care they provide.3

Conditions are grouped into categories known as indicator groups. These are:

  • Cardiovascular4

  • Respiratory5

  • Lifestyle6

  • High dependency and other long term conditions7

  • Mental health and neurology8

  • Musculoskeletal9

  • Fertility, obstetrics and gynaecology10

Prevalence of some conditions is measured as a proportion of the total number of people registered at a surgery, whereas others are age-specific.

QOF also provides information on the activity of GPs in relation to 25 measures overall - this is expressed as achievement.

Achievement scores are used to calculate what payment a general practice should receive according to the services it delivered.


  1. NHS Digital is the national information and technology provider for the health and care system. Our team of information analysis, technology and project management experts create, deliver and manage the crucial digital systems, services, products and standards upon which health and care professionals depend. During the 2016/17 financial year, NHS Digital published 292 statistical reports. Our vision is to harness the power of information and technology to make health and care better.

  2. There are 25 conditions and measures in total; the report has information on the prevalence of 21 of these. These 25 conditions and measures have been selected for the following reasons: where responsibility for ongoing management of the condition rests principally with the GP and the primary care team; where there is good evidence of the health benefits likely to result from improved primary care; and where the disease area is a priority.

  3. QOF payments to general practices are calculated from the achievement scores allocated to each indicator. The QOF rewards practices for the provision of 'quality care' and helps to fund further improvements in the delivery of clinical care. This year, the value of a QOF point was £165.18. This figure is subject to adjustment to account for factors specific to each surgery, such as population demographics.
