Delirium in Elderly Hospitalized Patients: Analyzing Clinical and Social Determinants in a Colombian Retrospective Cohort

Topic: Risk, prevention and care in population studies
The studied cohort comprised 4601 patients, mean age of 83.93 years and 56.26% were women. The prevalence of delirium upon admission was 22.39%. Key factors associated with delirium included older age (OR 1.04, 95% CI 1.01-1.06), malnutrition (OR 2.42, 95% CI 1.93-2.79), dementia (OR 2.57, 95% CI 2.02-3.38), functional impairment (OR 2.50, 95% CI 1.74-3.59), and oropharyngeal dysphagia (OR 1.49, 95% CI 1.08-1.99). Social determinants such as female sex, limited social networks, living alone, and enrollment in the subsidized health regime were not significantly associated with delirium. Delirium upon admission is highly prevalent among elderly inpatients and is associated with clinical factors, particularly malnutrition, dementia, and oropharyngeal dysphagia. Although no significant associations were found between social determinants of health (SDH) and delirium in this cohort, further research in diverse healthcare settings is needed to better understand the broader impact of SDH on delirium risk.

Key findings
- The studied cohort comprised 4601 patients, mean age of 83.93 years and 56.26% were women.
- The prevalence of delirium upon admission was 22.39%.
- Key factors associated with delirium included older age (OR 1.04, 95% CI 1.01-1.06), malnutrition (OR 2.42, 95% CI 1.93-2.79), dementia (OR 2.57, 95% CI 2.02-3.38), functional impairment (OR 2.50, 95% CI 1.74-3.59), and oropharyngeal dysphagia (OR 1.49, 95% CI 1.08-1.99).
- Social determinants such as female sex, limited social networks, living alone, and enrollment in the subsidized health regime were not significantly associated with delirium.
- Delirium upon admission is highly prevalent among elderly inpatients and is associated with clinical factors, particularly malnutrition, dementia, and oropharyngeal dysphagia.
Why it matters
In this Colombian cohort, delirium on admission was common and was linked to malnutrition, dementia, functional impairment and swallowing difficulty, while social factors showed no significant link. It identifies clinical risk factors but reports no treatment or cure for Alzheimer's disease.
