Individual delirium symptoms: do they matter?

Objectives: To evaluate the impact of individual manifestations of delirium on outcome, describe them in critically ill adults, and validate nurses' bedside item assessments from the Intensive Care Delirium Screening Checklist (ICDSC).

Design: Prospective study.

Setting: Single 16-bed medical/surgical university hospital intensive care unit.

Subsyndromal delirium in the ICU: evidence for a disease spectrum.

Objective: ICU delirium is common and adverse. The Intensive Care Delirium Screening Checklist (ICDSC) score ranges from 0 to 8, with a score of 4 or higher indicating clinical delirium. We investigated whether lower (subsyndromal) values affect outcome.

Incidence, risk factors and consequences of ICU delirium.

Objective: Delirium in the critically ill is reported in 11-80% of patients. We estimated the incidence of delirium using a validated scale in a large cohort of ICU patients and determined the associated risk factors and outcomes.

Design And Setting: Prospective study in a 16-bed medical-surgical intensive care unit (ICU).
