The NHS requires that there is good account of the use of public money. This includes checking on money paid to GPs for the services they provide to their patients.
So that checks can be made on surgeries, it is periodically necessary for Health Authority staff to be able to check selected medical records to see which patients came to the surgery and which services were provided to them. Checks like this will only be done by a few members of the Health Authority who work in complete confidentiality and they will have signed a special confidentiality agreement.
If you do not want your records to be part of such a financial check, please let the manager know, preferably in writing. Your objections will be respected.
