These professionals are being employed more and more, many working beyond their scope, eg. in GP, seeing undifferentiated patients (against the Leng recommendations). Patients have died due to PAs working above their competencies.
Trusts are still advertising for PAs/AAs when the role should be taken by a doctor, many of whom face unemployment. Patients are confused by these various 'consultants' who are not medically qualified. They think they're seeing a doctor. Doctors are being replaced! There is no way this should be the future for our NHS!
