Abstract

The aim of the study was to explore the association of dementia with in-hospital OBJECTIVE:The aim of the study was to explore the association of dementia with in-hospital death in acutely ill medical patients.METHODS:Thirty-four internal medicine and 4 geriatric wards in Italy participated in the Registro Politerapie SIMI-REPOSI-study during 2008. One thousand three hundred and thirty two in-patients aged 65 years or older were enrolled. Logistic regression models were used to evaluate the association of dementia with in-hospital death. Socio-demographic characteristics, morbidity (single diseases and the Charlson Index), number of drugs, and adverse clinical events during hospitalization were considered as potential confounders.RESULTS:One hundred and seventeen participants were diagnosed as being affected by dementia. Patients with dementia were more likely to be women, older, to have cerebrovascular diseases, pneumonia, and a higher number of adverse clinical events during hospitalization. The percentage of patients affected by dementia who died during hospitalization was higher than that of patients without dementia (9.4 versus 4.9%). After multiadjustment, the diagnosis of dementia was associated with in-hospital death (OR = 2.1; 95% CI = 1.0-4.5). Having dementia and at least one adverse clinical event during hospitalization showed an additive effect on in-hospital mortality (OR = 20.7; 95% CI = 6.9-61.9).CONCLUSIONS:Acutely ill elderly patients affected by dementia are more likely to die shortly after hospital admission. Having dementia and adverse clinical events during hospital stay increases the risk of death.
