Figures show the recorded prevalence of 14 conditions1, including asthma, hypertension, dementia and diabetes.

The prevalence data is collected from General Practices in Northern Ireland and the publication presents disease register sizes and raw disease prevalence rates2, broken down to LCG, GP Federation and General Practice level.

This robust dataset is made up of information voluntarily provided by all 314 General Practices in Northern Ireland. The data are collected through the Quality and Outcomes Framework (QOF).  As a means of stabilising GMS, QOF was suspended for payment purposes for the 2023/24 year, with no financial detriment to General Practices. Although QOF was suspended, disease registers are still maintained by General Practices, allowing prevalence data to continue to be collected.  The data source is the General Practice Intelligence Platform (GPIP)/QOF (GPIP/QOF), a Northern Ireland IT system that supports the QOF process.

The 14 disease registers are grouped into categories, which are:

  • Cardiovascular3
  • Respiratory4
  • High dependency and other long term conditions5
  • Mental health and neurology6

Prevalence of some conditions is measured as a proportion of the total number of people registered at a surgery, whereas others are age-specific.7

This year’s publication includes a report and data tables.

Notes to editors: 

  1. There are a total of 18 individual areas within 4 domains within the Quality and Outcomes Framework (QOF), of which 14 can be used to calculate the prevalence of conditions within the population. 
  1. Raw prevalence rates take no account of differences between populations in terms of their age or gender profiles, or other factors that influence the prevalence of health conditions. Year-on-year changes in the size of disease registers are influenced by various factors including changes in prevalence of the condition within the population; demographic changes, such as an ageing population; improvements in case finding by practices; and changes to the definition of the register.
  1. The cardiovascular group contains information on:
  • Atrial fibrillation
  • Coronary heart disease
  • Heart failure
  • Heart failure due to left ventricular systolic dysfunction
  • Hypertension
  • Stroke
  1. The respiratory group contains information on:
  • Asthma
  • Chronic obstructive pulmonary disease
  1. The high dependency and other long term conditions group contains information on:
  • Cancer
  • Chronic kidney disease
  • Diabetes mellitus
  • Non-diabetic hyperglycaemia
  1. The mental health and neurology group contains information on:
  • Dementia
  • Mental health
  1. Two of the disease registers have a specific age requirement.  These diseases and their age requirements are Chronic Kidney Disease 18+ and Diabetes Mellitus 17+.  Within this publication, raw prevalence rates are calculated using both the full list and separately using the relevant age group.
