In 1991 up to 37% of general practitioners (GPs) used homeopathy,[1] but a review carried out by West Kent NHS Primary Care Trust in 2007 found that less than 1% of registered patients were referred for homeopathic treatment, and that this was almost always at the patient's request rather than as the result of a clinical decision.[37] In 2011 the British Homeopathic Association said that 400 GPs used homeopathy in their everyday practice.[38][39] The British Homeopathic Dental Association (BHDA) claimed to have 69 dentists,[40] while the British Association of Homeopathic Veterinary Surgeons had 36 vets listed as members.[41] There are over 41,000 GPs[42] and around 24,000 registered veterinary surgeons[43] in the UK, and almost 23,000 dentists doing NHS work in England.[44]
