One million adults in the United States receive mechanical ventilation for acute respiratory failure in the intensive care units (ICUs) annually and up to 80% of them develop delirium during their ICU stay. Presence of delirium predisposes older adults to immediate in-hospital complications including a longer length of ICU and hospital stay, increased risk of in-patient mortality and elevated costs of care. In addition, ICU delirium is associated with long-term post-discharge complications such as development of cognitive impairment and dementia.~Recent research studies exploring pharmacological strategies to manage ICU delirium have not demonstrated efficacy; a limitation also acknowledged in the Society of Critical Care Medicine 2018 Pain, Agitation/Sedation, Delirium, Immobility, and Sleep Disruption guidelines. Music listening is a non-pharmacological intervention that has shown to decrease over-sedation, anxiety and stress in critically ill patients, factors that could predispose to ICU delirium. Our team is now proposing to conduct a large randomized clinical trial called Decreasing Delirium through Music (DDM) in Critically Ill Older Adults to evaluate the efficacy of a seven-day slow-tempo music intervention on the primary outcome of delirium/coma free days among mechanically-ventilated older adults admitted to the ICU.
Critically ill older adults admitted to the intensive care unit (ICU) are at a higher risk to develop delirium, which predisposes them to longer lengths of ICU and hospital stay, increased in-patient mortality, and higher risk of new acquired cognitive impairment and dementia. Music listening is a non-pharmacological intervention that holds potential to decrease ICU delirium. The investigators propose a randomized controlled trial to evaluate the efficacy of a seven-day slow-tempo music intervention on the primary outcome of delirium/coma free days among mechanically ventilated, critically ill older adults.
