What are the effects of advance treatment directives for people with severe mental illness?
The review contains only 2 trials, and the data available are too limited to make definitive recommendations. While the more intensive joint crisis planning appears to be more effective at reducing involuntary admissions to hospital than a less intensive form of advance directive, there is not enough evidence to evaluate their effectiveness.
An advance directive is a document specifying a person's preference for treatment, should he or she lose capacity to make such decisions in the future. Advance directives have been used in end-of-life settings to direct care but should be well-suited to the mental health setting.
