Frequently Asked Questions
What is Patients Know Best?
Patients Know Best is an online patient portal that gives you access to some of the information on your personal health record at our hospitals.
You can log in by visiting the Patients Know Best website, on your phone, tablet or desktop computer.
The portal allows you to view some of your healthcare information such as hospital appointment information and allergies.
Can I still use Patients Know Best even after the hospital stops using it?
Yes, although no new information will be added by our hospitals from 18th December 2025. The record in PKB is yours and you will still be able to add information such as measurements, allergies, medicines taken, to use with other healthcare professionals or organisations who use PKB.
What will happen to the information about me in PKB?
Your record in PKB still remains yours and you can access it exactly as before. PKB will not delete or remove your access to your record at any time.
Our hospital will no longer have access to the information you added into PKB which are symptoms, videos, and any linked devices. If you still want to use PKB, your PKB record is still available to you for 8 years after the last time you log in.
What do I do if I no longer want to have a PKB account?
If you no longer want to use your PKB account, you can contact their helpdesk here - Submit a ticket - who can help you with this.
Will I still be able to send messages and interact with the doctors and nurses on my team at the hospital?
No. Our healthcare teams will no longer be able to use PKB from Thursday, 18th December 2025, which means they will not have access to messages, or your PKB record.
Can I still use the videos and symptom tracker?
Yes. You will still be able to access these videos and log your symptoms. Though please note that these will no longer be accessible or updated by your healthcare team at our hospitals.
If I attend another hospital in the future that uses PKB can I use my same record again?
Yes. If you attend another hospital provider who uses PKB they will be able to link your existing record.
Why have you stopped using PKB?
We have another portal called DrDoctor which we use for our digital letters, and where we have had positive feedback from our patients. In early 2026 we will be adding more functionality into Dr Doctor to improve the experience of our patients and avoid having multiple systems.
Why do I have admissions that are still open in PKB?
If you were an inpatient with us on 18th December 2025, this will still show as active. This is because we are no longer able to update PKB after this date to be able to mark you as discharged.
