Pilot Prospective Study of Post-Surgery Sleep and EEG Predictors of Post-Operative Delirium

Delirium, a fluctuating disturbance of attention and awareness that develops over a short time period, occurs post-operatively in 37% of patients and is associated with poor outcomes, cognitive decline, longer hospital stays, and increased costs, morbidity and mortality (Dyer et al., 1995; Flink et al., 2012; Shim and Leung, 2012). Yet, interventions are extremely limited. It is impossible to identify the impending onset of delirium early enough to allow development or implementation of preventative therapies.
