This document discusses delirium, which has been proposed as a "never event" by CMS. It summarizes evidence that delirium is common in ICU patients, associated with worse outcomes, and risk factors include older age, medications like benzodiazepines and opioids. Multicomponent protocols including monitoring, mobility, and reducing modifiable risk factors can help prevent delirium. Daily interruption of sedation with spontaneous breathing trials may help reduce duration of mechanical ventilation and ICU stay. Alternative sedatives like dexmedetomidine that are less likely to cause delirium should be considered over benzodiazepines when possible.

3. Delirium: A never event? Maybe
not yet……BUT
• Delirium proposed by CMS as a “Never Event”
• “Never Events” are errors in medical care that are
clearly identifiable, preventable, and serious in
consequences and indicate a problem in the safety
of a healthcare facility.
• The proposal has given delirium publicity
• Increased interest and research in this topic

• 65-70% goes undiagnosed if routine monitoring is
not implemented

36. Are we making any progress?
• Growing awareness about delirium and associated
outcomes
• Better monitoring instruments for health care providers
at bedside
• Identification of potential mechanisms and risk factors
• Non pharmacological interventions have shown promise
in non-ICU cohorts and in ICU cohorts (early
mobilization)
• Reducing benzodiazepine exposure with alternative
sedation paradigms, especially dexmedetomidine has
shown improvements in delirium rates and duration
