Objective: The aim of the study was to know the incidence and prevalence of delirium in adults older than 85 years hospitalized in a geriatric acute unit. Methodology: This was an observational, descriptive study. A total of 224 patients, aged 85 and over, were hospitalized at the Clínica Médica Sur hospital in the period of 2015-2016. Results: 224 patients were included, mean age 89.3 ± 3.2, schooling 11.8 years, functionality measured by the Charlson index greater than two points 54%. In the analysis, patients with delirium had a higher risk of mortality odds ratio (OR) 7.5 with a confidence interval (CI) 2.84-19.92 (p ≤ 0.0001), an increase in hospital stay with an OR 3.27 CI 1.82-5.89 (p ≤ 0.0001). Predisposing factors, a Charlson index > 2 points had an OR of 2.28 IC 1.25-4.16 (p = 0.006), functionality by Katz < 5B had an OR of 2.82 IC 1.32-6.03 (p = 0.006) for delirium. The comprehensive geriatric assessment decreased delirium with an OR 0.5 IC 0.28-0.87 (p = 0.02). Conclusions: The prevalence of delirium in this population was 25.9%, cumulative incidence 7.5%. The incidence of delirium was associated with a longer hospital stay and mortality. Comprehensive geriatric evaluation was associated with a lower incidence of delirium.
