Hospitalisation and compulsion: the research agenda.

Keown et al's paper highlights the complex nature of social determinants of hospital admission and compulsory care. We review here how research into compulsion in mental health has progressed beyond epidemiological studies of rates of admission. There is now a wider recognition of the range of compulsory and coercive processes used and how they are experienced by patients. The results of recent studies have confirmed the importance of confronting the complexity that Keown et al have presented. They have also produced unexpected and intriguing findings that set the direction for future research.
