We included both randomised controlled trials and controlled evaluations of fall prevention interventions for people aged 60 and over with any mental health problem including dementia, depression or psychosis. Studies that did not have a specific mental health focus were included as long as a significant percentage (e.g. 50% or more) of participants had a mental health problem, or data was reported separately for those with a mental health condition. As preliminary searches suggested there was a lack of controlled studies we included uncontrolled studies, but only if all participants had a mental health problem. We included single focus or multi-factorial interventions involving environmental, exercise, technological, psychological, educational, and health related components. Our primary interest was in studies delivered in in-patient mental health settings but interventions delivered in other settings were included as long as the study included older people with a mental health problem. The primary outcomes of interest were the number of participants sustaining at least one fall (fallers) and data relating to the rate or number of falls. Secondary outcomes included fall related injuries, hip fractures, service use and patient satisfaction. In addition, we searched for qualitative studies or process evaluations that identified barriers and facilitators to the implementation and uptake of interventions; in particular looking at whether specific guidance is required for this group.
