The purpose of this study was to use rigorous systematic review methods to summarise the effectiveness of interventions for elder abuse. Only eight studies met the inclusion criteria. Evidence regarding the recurrence of abuse following intervention was limited, but the interventions for which this outcome was reported failed to reduce, and may even have increased, the likelihood of recurrence. Elder abuse interventions had no significant effect on case resolution and at-risk carer outcomes, and had mixed results regarding professional knowledge and behaviour related to elder abuse. The studies had significant methodological limitations that limit the ability to draw conclusions about the effectiveness of these interventions.
