Why it's important
Every time you have any interaction with the NHS, information about you is collected.
For example, any medication you are prescribed is recorded, as are hospital test results so they can be shared with your GP.
Capturing important information like this, along with records of previous treatments, allergies or reactions to certain medicine gives a full picture to NHS staff, and makes it easier for them to give you the care you need.
Beyond your own individual health, there are wider uses of patient data that are vital to how the NHS functions.
By understanding health trends in your area, local NHS services can be commissioned to meet specific needs.
Research within the NHS needs patient data to make advances in care and treatment that have long-term benefits for everyone.
