What you can find out
You can find out how common certain health conditions are. This is called prevalence, and is the percentage of all patients who have the condition. For example if 10 patients out of a hundred patients have asthma, this is a 10 per cent prevalence. You can compare this against the national average, and against regional and local averages.
You can find out how condition prevalence has changed over time
What the report can't tell you
You can't use the figures to determine the total number of patients with a particular condition, or find the condition prevalence figures used to calculate QOF payments, because:
Only practices that could be mapped to parent organisations on 1 April 2017 are included (this means that data for practices that closed prior to this date are not included)
The data are taken from QOF, which is a voluntary data collection
The data are taken from QOF publications. The data for these publications are available in .csv format, along with information on QOF, on the Quality and Outcomes Framework pages.
