Delirium affects between 14% and 56% of older hospitalized patients.
It is linked to increased risk for death, postoperative complications, longer hospital and intensive care unit stays, and functional declines. To lessen or prevent the occurrence of delirium, hospitals have implemented multicomponent interventions.
Most are effective in preventing the onset of delirium in at-risk patients in a hospital setting, according to a systematic review of 19 studies. Evidence from the review was insufficient to determine the benefit of such programs in palliative care or long-term care settings.
In addition, the evidence was insufficient to identify which multicomponent interventions are most beneficial, and the studies do not address the question of which components within a program provided the most benefit for delirium prevention.
