A study from the King’s Fund and the Centre for Mental Health (Naylor et al., Mental illness is responsible for 23% of England’s total burden of disease, but receives only 13% of NHS health expenditures (Centre for Economic Performance, 2012). These regional commissioning bodies were PCTs, but have been replaced by Clinical Commissioning Groups as part of the NHS reforms detailed in section 3.1. Following the current NHS reforms, a percentage of the health care budget is to be directed towards Public Health England, to be used by Local Authorities to commission public health services.
