Why is it important to use patient data?

There is huge potential to make better use of information from patient records. Data is vital for your individual care, and to improve health, care and services across the NHS.

Giving individual care

Good quality information is essential to inform our clinical care. Everyone should have access to information about their own healthcare, to check the information is accurate and to help manage any condition. Your whole care team, whether in a GP practice, a hospital or a care home, needs to have access to up-to-date information about you to inform your treatment, and to provide the best care.

Improving health, care and NHS services

If small amounts of data from many patients are linked up and pooled, researchers and doctors can look for patterns in the data, helping them develop new ways of predicting or diagnosing illness, and identify ways to improve clinical care. The information can be used to help:

  • understand more about disease risks and causes
  • improve diagnosis
  • develop new treatments and prevent disease
  • plan NHS services
  • improve patient safety
  • evaluate government and NHS policy.

You can find examples of how data is used for each of these purposes in our searchable bank of case studies
