Anonymous data

Sometimes we are asked to share information to other organisations, like the Health Authority, to help them check and improve services. Before we share any information, we remove details that could identify you, such as your name. This means the information is anonymous.

The NHS uses anonymous information from GP surgeries, hospitals and other health services to understand how care is being provided and where improvements are needed.

This information will allow the NHS to compare the care you received in one area against the care you received in another, and make improvements where and if necessary.

Information such as your postcode and NHS number, but not your name, will be used to link your records in a secure system, so your identity is protected.

This information can help people who plan NHS services and carry out health research to improve care for patients.

There are strict laws and rules to protect your privacy.

You can choose not to have your information used in this way. To find out more, visit the NHS website. To find out more, visit www.nhs.uk.
