To determine the occurrence of delirium in oncology inpatients and to identify and evaluate admission characteristics associated with the development of delirium during inpatient admission, a prospective observational study was conducted of H 3 patients with a total of 145 admissions with histological diagnosis of cancer admitted to the oncology unit over a period of ten weeks. At the point of inpatient admission, all patients were assessed for the presence of potential risk factors for development of delirium. During the index admission patients were assessed daily for the presence of delirium using the Confusion Assessment Method. Delirium was confirmed by clinician assessment. Delirium developed in 26 of 145 admissions (18%) and 32 episodes of delirium were recorded with 6 patients having 2 episodes of delirium during the index admission. Delirium occurred on average 3.3 days into the admission. The average duration of an episode of delirium was 2.1 day. Four patients with delirium (15%) died. All other cases of delirium were reversed. Factors significantly associated with development of delirium on multivariate analysis were: advanced age, cognitive impairment, low albumin level, bone metastases, and the presence of hematological malignancy. Hospital inpatient admission was significantly longer in delirium group (mean: 8.8 days vs 4.5 days in nondelirium group, P<.01). Delirium among hospitalized oncology patients is a common condition. Identification of risk factors to delirium at the time of inpatient admission can be used to recognize those patients at the greatest risk and may aid prevention, early detection and treatment.
