Introduction

Dementia is one of the leading causes of disability and burden in Western countries. In Portugal, there is a lack of data regarding dementia prevalence in hospitalized elderly patients and factors associated with in-hospital adverse outcomes of these patients.

Objectives

Determine dementia prevalence in acutely-ill medical hospitalized elderly patients and its impact in health outcomes.

Methods

All male patients (> 65 years) admitted to a medical ward (> 48 h) between 1.03.2015 to 31.08.2015 were included in the study. Patients were excluded if unable to be assessed due to sensorial deficits, communication problems or severity of the acute medical condition. Baseline evaluation included socio-demographic variables, RASS, NPI, Barthel Index and Confusion Assessment Method.

Results

The final sample consisted of 270 male subjects with a mean age of 80.9 years, 116 (43%) having prior dementia. Dementia patients were significantly older (83.5 vs 78.9; P < 0.001) and had lower values of Barthel Index (dementia: 34.8 vs non-dementia: 85.8; P < 0.001). Mortality rate (9,3%) and length of hospitalization (11.2 days) were similar between groups (12.1 vs 7.1; P = 0.204 and 11.9 vs 10.6; P = 0.218, respectively). Patients with dementia had higher rates of all neuropsychiatric symptoms except depression, anxiety and mood elation. The level of consciousness (measured by RASS) was impaired in 50% of patients with dementia, which was significantly higher than in non-demented subjects (12.3%; P < 0.001). Delirium rates were 29.5% in dementia compared with 7.1% in controls (P < 0.001).

Conclusions

There is a high prevalence of dementia and an appreciable rate of delirium among these patients.
