Preventing delirium: should non-pharmacological, multicomponent interventions be used? A systematic review and meta-analysis of the literature

Multicomponent interventions are effective in preventing incident delirium among elderly inpatients. Effects seemed to be stable among different settings. Due to the limited amount of data, potential benefits in survival need to be confirmed in further studies. Future research should be aimed at contrasting different multicomponent programmes to select the most useful interventions.
