Patients Know Best

An online portal that puts you in control of your medical records

We are introducing a new way for our patients to be able to see their medical information online, any time, anywhere.

Patients Know Best (PKB) is a secure online portal that allows you to store your health records in one place to give you instant access to and better control of important information such as appointment letters, test results, care plans and medical correspondence between you and your healthcare team.

Building an online record of your health can help keep you and those involved in your care informed more regularly, which can lead to better decisions about your health and the care that you need.  

With the Patients Know Best portal, you can:

We chose this system because it meets the strict NHS requirements for health record systems and is fully compliant with the Data Protection Act 2018. All personal and health information is encrypted (or coded), with the company that provides PKB having access only to your NHS number. This means only you and the people you choose can access your health information.

If you want the family member or carer to have access to your record they can be added in the “sharing” section. This will mean they can set up their own account and you can control the level of access they have to your record.

We are unable to add any information until you have registered. Once you have registered, your correspondence will start to become available. In the meantime, you can add your own information, such as tracking your symptoms or recording any allergies or medication you take.
