The NHS Constitution sets out that patients have the right to drugs and treatments that have been recommended by a National Institute for Health and Clinical Excellence (NICE) technology appraisal, if their doctor says they are clinically appropriate. This includes psychological therapies appraised by NICE. The right is underpinned by a statutory funding direction, in place since January 2002, which requires primary care trusts to make funding available for drugs and treatments recommended in a NICE technology appraisal, normally within three months of publication of the appraisal.
