OBJECTIVE:

To describe and analyze the clinical characteristics, functionality, nutritional, and social aspects in patients with Advance Dementia (AD), and to hospitalized in the geriatric unit in the Hospital Universitario San Ignacio (HUSI) and it how it is related with hospital outcomes, compare with no advanced dementia.

METHODS:

A cross-sectional study was conduct, in patient hospitalized in the geriatric unit in the HUSI, with a retrospective review of electronic medical charts from January of 2016 to December 2017. The dependent variable was AD, a univariate, bivariate and multivariate analysis was made.

RESULTS:

1091 patients had dementia, 606 with AD, the median age was 86 years and the women prevalence were (57.3 %) higher than men. In the AD group, compared with those with dementia, had high percentage of malnutrition (91.1 %%), pressure ulcers (26.2 %%), delirium (67.2 %%), polypharmacy (68.3 %%), longer hospital admission (median of 5 days vs 4 days), medical complication (10.6 %%), and mortality (16.9 %%). We found a higher association with malnutrition with AD (OR = 2.80, CI = 1.94-4.06, p < 0.00), polypharmacy (OR = 1.41, CI = 1.07-1.86, p = 0.012), delirium (OR = 2.24, CI = 1.72-2.92, p < 0.00), pressure ulcers (OR = 3.75, CI = 2.455.73, p < 0.00) and mortality (OR = 2.21,CI = 1.42-3.44, p < 0.00).

DISCUSSION:

The advance aged in our patients, might be a determinant in the high percentage of dementia that we found. AD is an entity that predispose to higher clinical outcomes as malnutrition, polypharmacy, delirium, pressure ulcers and mortality. As previously shown there is a need for a comprenhensive geriatric assessment in elderly with dementia, to improve hospital outcomes.
