Current health policies emphasize partnership between professional groups, between agencies and with users, to ensure more integrated health and social care services. However, a number of reasons have been consistently identified as inhibiting interprofessional working. Among the many factors identified are poor communication, conflicting power relations and role confusion, and these present immense challenges to those who wish to offer interprofessional education and training opportunities. East Gloucestershire NHS Trust worked in partnership with the University of Gloucestershire (formerly the Cheltenham and Gloucester College of Higher Education) to overcome these problems and deliver an important postqualifying interprofessional training for those working with people with serious mental illness - the Thorn-based 'Diploma in Integrated Approaches to Serious Mental Illness'. This collaborative initiative represents a good model by which practitioners of all disciplines can be trained to a high standard and meet the requirements of the National Service Framework for Mental Health. This paper describes the initiative and identifies the extent to which the course has, by mirroring the practice it is seeking to generate, 'pulled together' to ensure interprofessional, intersectoral and professional/user collaboration. The key challenges associated with interprofessional working (with people with serious mental illness and with others) and with course implementation and how these were met are discussed and further opportunities are identified.
