The surgery is involved in the teaching and mentoring of Registrars. These are trained and fully qualified doctors who have experience in hospitals and now wish to become GPs.
These registrars undertake all aspects of being a GP (consultations, house visits etc), and are under the supervision of one of the doctors in the practice during their time at the practice.
On occasions, the registrars will need to make videos of their consultations. This will only occur if the patient has consented for the video to be used, and refusal will not affect your care with the doctor in any way.
