Comparison of the confusion assessment method for the intensive care unit (CAM-ICU) with the Intensive Care Delirium Screening Checklist (ICDSC) for delirium in critical care patients gives high agreement rate(s).

OBJECTIVE: In the intensive care unit (ICU) we assessed the agreement between the delirium ratings of two independent delirium assessment methods: (a) the Confusion Assessment method for the ICU (CAM-ICU); and (b) the Intensive Care Delirium Screening Checklist (ICDSC).

DESIGN: Prospective, descriptive cohort study.

SETTING AND PATIENTS: During a 6-month period, 174 patients (mean age 62.4+/-13.0 years) admitted to the ICU after elective surgery or after an emergency were included and assessed with both delirium assessment systems by two trained independent investigators (research person and bedside nurses) during their ICU stay or for up to 7 days after ICU admission.

INTERVENTIONS: Patients' clinical characteristics at ICU admission day were documented.

MEASUREMENTS AND RESULTS: After excluding permanently unconscious patients with
CONCLUSION: It is concluded from the present investigation that the two scoring methods represent good diagnostic tools with high agreement rates in critical ill ICU patients.
