Assessment of mental capacity: who can do it?

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.
