The incidence of delirium has been difficult to define in the ICU since no validated simple delirium assessment instrument exists. Consequently identifying risk factors for delirium in the ICU in an attempt to develop preventative strategies has proved difficult. This study validates the Confusion Assessment Method for ICU patients (CAM-ICU) and determines the incidence of delirium in the ICU.
Delirium occurred in 83% of patients during their ICU stay for a mean of 2.4 days. Two ICU nurses using the CAM-ICU had sensitivities of 100% and 93%, and specificities of 98% and 100% for the diagnosis of delirium when compared with assessments by delirium experts. Duration of CAM-ICU assessments was two (mean) minutes.
Prospective cohort study over 6 month period involving 111 mechanically ventilated patients in the ICU, comparison of nurse led CAM-ICU delirium assessments with those by delirium experts
