Assessment of mental capacity: Who can do it?

Abstract

Aims and methods: To determine the point prevalence of mental incapacity and the 'Bournewood gap' in general adult and old age mental health in-patients. The correlation of mental capacity assessment between doctors and nurses was investigated. Data were gathered on one census day for all general adult and old age psychiatric in-patients at three hospital sites. Results: Half the sample lacked capacity and one third fell into the 'Bournewood gap'. The capacity assessment by nurses and doctors correlated highly (κ=0.719, P=0.0001). Clinical implications: 'Bournewood gap' patients should have their needs assessed in order to identify and protect their rights. Appropriately trained mental health nursing staff can undertake this assessment.
