ObjectiveTo study the presence of co-morbidity and delirium and to determine whether these factors are predictors of hospital and shortterm mortality in elderly patients acutely admitted to a department of internal medicine.DesignProspective cohort study.MethodSocial and demographic data as well as data on their physical and cognitive limitations were collected from consecutive patients of 65 years and older who were hospitalised in the period from I December 2002 to 30 June 2005 in the Academic Medical Centre in Amsterdam, the Netherlands. Co-morbidity and ICD diagnosis were determined on discharge from the hospital. Three months after discharge the patients' circumstances were assessed.ResultsA total of 461 patients, 195 men and 266 women with an average age of 78.2 years (SD: 7.8), were included. Of these patients, 132 (28.6%) had cognitive impairment and the mean number of limitations with regard to the activities of daily living (ADL) was 5.48 (10.4%) patients died in hospital and another 74 patients (16.1%) had died 3 months after discharge. The only independent predictor of hospital mortality was delirium at admission (OR: 2.28; 95% CI: 1.23-4.21). Independent risk factors for mortality within 3 months after discharge were: delirium at admission (OR: 2.20; 95% CI: 1.12-4.31), pre-admission ADL limitations (OR: 1.11; 95% CI: 1.02-1.21), a diagnosed malignancy (OR: 5.96; 95% CI: 2.45-14-52), and a higher Charlson co-morbidity index (OR: 1.19; 95% CI: 1.04-1-34).ConclusionAt discharge from the hospital, the risk of death within 3 months after discharge in acutely hospitalised patients of 65 years and older was determined by a combination of delirium at admission, pre-admission ADL limitations, a malignancy, and co-morbidity. These results can be used to identify elderly patients who might benefit from comprehensive geriatric assessment during hospitalisation and from a well-prepared discharge planning that takes their co-morbidity into consideration.
