Payment by results (PbR) for mental health services is currently being piloted with the aim of arriving at a national tariff for mental health by 2013/2014. The Department of Health has also established two pilot sites to consider applicability of PbR for learning disability services. This article outlines the concept of PbR in learning disability services and describes the progress of the pilot work being undertaken in this area.

Psychological treatments are widely used for the management of mental health and behavioural problems in people with intellectual disabilities. The evidence base, including the cost-effectiveness of such interventions, is limited. This editorial explores the current evidence base and analyses its strengths and limitations. The editorial also highlights current problems in conducting randomised controlled trials in this area and suggests a way forward.

Mental capacity refers to a person's ability to make decisions, which may include consenting to medical treatment. People are presumed to have this capacity. Individuals may lack capacity because of an impairment or disturbance that affects the way their mind or brain works. Legal frameworks are in place for acting and making decisions on behalf of individuals who lack the mental capacity to do so for themselves, in their best interests. A case illustration is used to outline the principles involved under the Mental Capacity Act 2005 for England and Wales. We describe in detail the assessment of capacity to consent to treatment in this case and good practice in making best interests decisions in everyday clinical practice.
