The impact of delirium in the intensive care unit on hospital length of stay
Open accessAbstract
Abstract.Study objective: To determine the relationship between delirium in the intensive care unit (ICU) and outcomes including length of stay in the hospital. Design: A prospective cohort study. Setting: The adult medical ICU of a tertiary care, university-based medical center. Participants: The study population consisted of 48 patients admitted to the ICU, 24 of whom received mechanical ventilation. Measurements: All patients were evaluated for the development and persistence of delirium on a daily basis by a geriatric or psychiatric specialist with expertise in delirium assessment using the Diagnostic Statistical Manual IV (DSM-IV) criteria of the American Psychiatric Association, the reference standard for delirium ratings. Primary outcomes measured were length of stay in the ICU and hospital. Results: The mean onset of delirium was 2.6 days (S.D.±1.7), and the mean duration was 3.4±1.9 days. Of the 48 patients, 39 (81.3%) developed delirium, and of these 29 (60.4%) developed the complication while still in the ICU. The duration of delirium was associated with length of stay in the ICU (r=0.65, P=0.0001) and in the hospital (r=0.68, P<0.0001). Using multivariate analysis, delirium was the strongest predictor of length of stay in the hospital (P=0.006) even after adjusting for severity of illness, age, gender, race, and days of benzodiazepine and narcotic drug administration. Conclusions: In this patient cohort, the majority of patients developed delirium in the ICU, and delirium was the strongest independent determinant of length of stay in the hospital. Further study and monitoring of delirium in the ICU and the risk factors for its development are warranted.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
