Physical health assessment for people with a serious mental illness (SMI) has been a neglected issue, with all the evidence showing that mental health nurses (MHNs) and associated practitioners need to develop such skills. The University of Huddersfield and South West Yorkshire Partnership Foundation Trust collaborated in a Physical Skills Project with the aim of facilitating knowledge and skills for MHNs. The development of the education and training workshop is presented. The results of a pre- and post-test evaluation of diabetes, evaluation of the workshop and, finally, implications for practice with regard to transferable knowledge and skill, are discussed.
