Peter Lepping is involved in major research on coercive measures and aggression on staff in psychiatry. This work is in association with colleagues from the European Violence in Psychiatry Research Group (EViPRG), of which he is a longstanding member. By pooling large amounts of data from various European countries, Peter and his colleagues from EViPRG have shown that differences in the use of coercion are much less country dependent than was previously believed. He has supported the development of work in India on coercion, together with conferences and projects to increase awareness of, and reduce the use of, coercion in Indian hospitals. Our work was the basis for guidelines for the use of coercion in Indian healthcare settings, which was published with our Indian colleagues. More locally, our work has been used to reduce coercion and aggression on staff across BCUHB. In addition, Peter’s work on capacity and ethics has been used to improve the awareness of and the use of the Mental Capacity Act and Mental Health Act in North Wales.
