Excerpt
Delirium is associated with prolonged intensive care unit (ICU) stay: its early recognition, treatment and prevention are becoming increasingly important. Scales and evaluation tools for delirium are becoming more diffuse, but a universal tool has not been defined yet, and probably delirium underrating still permeates the ICU environment. Spronk [
1] investigated, during daily care, intensivists’ and ICU nurses’ skills in identifying the presence of delirium in ICU patients. In a 3-month period, all patients in the ICU for more than 48 h were screened daily for delirium both by attending intensivists and nurses. The Confusion Assessment Method for the ICU (CAM-ICU) was used as a screening instrument for delirium. During the study period, 46 patients (30 male, 16 female; median age 73 years) with an ICU stay of 6 days (range 4–11) were evaluated. CAM-ICU scores were obtained during 425 patient days. Considering the CAM-ICU as the reference standard, delirium occurred in 50% of the patients with a duration of 3 days (range 1–9). Days with delirium were poorly recognized by doctors (sensitivity 28.0%; specificity 100%) and ICU nurses (sensitivity 34.8%; specificity 98.3%). Recognition did not differ between hypoactive or active status of the patients involved. Delirium is severely underrecognized in the ICU in daily care. These data indicated that more attention should be paid to the implementation of a validated delirium-screening instrument during daily ICU care. …
