If she is working in the surgery, whether in admin or clinical role, she is bound by confidentiality rules. If she breaks them, the consequences for her (and the practice) are severe. It does happen, of course, as there idiots in any walk of life- but it’s not that common.
I’m not sure how you could stop her accessing your records- it would be an administrative nightmare for the surgery to ensure it never happened. And in an emergency, for instance, it may be a bad idea. I doubt they could agree to guarantee she never handle information about you. If she works on reception, for instance, and she answers the phone and it’s you- are you going to demand to put through to someone else? You could hang up and call later- but if a pain for you (and you may just get her again). If she deals with admin, she may be dealing with the electronic or paper letters or results from the hospital- putting them into the correct record- she won’t know it’s yours until she opens the envelope in the case of hard copies, in the case of electronic- what does she do if that is her task? Disturb someone else to come and do yours specifically? Put it to the back of the list for someone else to do another day? Similarly if she is the secretary who types the referral letters- what if no-one else does this role? Or it might mean your referral letters are delayed if it has to be put back on the list for someone else to do. If she is a nurse or gp, it may be easier in that you can ask not to see her. But gp’s do have to deal with results from others in the practice sometimes- e.g. if the gp who ordered a test is on holiday or not in.
If you are adamant she must not see your record then I think you will have to register at another surgery.
You can apply to the practice to have your records locked, OP. This is what is done if someone is a patient at the same surgery where they work. You can stipulate who can and who cannot access your record. That way she could only access it if she uses someone else's smartcard, which would be gross misconduct. You may be asked to justify your request if your only concern is that you think she's 'a bit mouthy' but if, for instance, you have particularly sensitive issues in your records I can't think why the practice would not agree.
