Abstract:Objective:The objective was to derive a risk score that uses variables available early during the emergency department (ED) encounter to identify high-risk geriatric patients who may benefit from delirium screening.
Methods:This was an observational study of older adults age ≥ 75 years who presented to an academic ED and who were screened for delirium during their ED visit.Variable selection from candidate predictors was performed through a LASSOpenalized logistic regression. A risk score was derived from the … Show more
“…Some researchers have proposed multiparametric tools for predicting delirium onset in hospital patients [ 4 , 5 ]. Despite their good performance, these tools require the collection of several anamnestic, physiologic and laboratory parameters, and are not always centered on the characteristics of geriatric patients.…”
Purpose
Delirium risk assessment in the acute-care setting generally does not account for frailty. The objective of this retrospective study was to identify factors associated with delirium, considering the interdependency of clinical variables with frailty syndrome in complex older patients.
Methods
The clinical records of 587 participants (248 M, median age 84) were reviewed, collecting clinical, anamnestic and pharmacological data. Frailty syndrome was assessed with the Clinical Frailty Scale (CFS). Delirium was the main study endpoint. The correlations of the considered anamnestic and clinical variables with delirium and its subtypes were investigated selecting only those variables not showing a high overlap with frailty. Correlations associated with a 25% excess of frequency of delirium in comparison with the average of the population were considered as statistically significant.
Results
Delirium was detected in 117 (20%) participants. The presence of one among age > 85 years old, CFS > 4 and invasive devices explained 95% of delirium cases. The main factors maximizing delirium incidence at the individual level were dementia, other psychiatric illness, chronic antipsychotic treatment, and invasive devices. The coexistence of three of these parameters was associated with a peak frequency of delirium, ranging from 57 to 61%, mostly hypoactive forms.
Conclusions
In acute-care wards, frailty exhibited a strong association with delirium during hospitalization, while at the individual level, dementia and the use of antipsychotics remained important risk factors. Modern clinical prediction tools for delirium should account for frailty syndrome.

Purpose of the Review
Globally, emergency departments are recognizing their rapidly growing number of older adult patients and some have responded with care models and associated processes broadly described under the umbrella of geriatric emergency departments (Geriatric EDs). This review seeks to identify emerging themes in the Geriatric ED literature from the period 2018–2023 to provide a synthesis of concepts and research to assist emergency medicine healthcare professionals and policymakers in improving the delivery of emergency medical care to older patients.
Recent Findings
Emerging themes in Geriatric EDs include “calls to action” in the field regarding 1) health system level integration; 2) developing care processes; 3) implementing minimum Geriatric ED standards; and, 4) setting future research agendas. The research is international in scope with contributions from Canada, Australia, United Kingdom, Belgium, and the United States among others. A focus on Geriatric EDs’ financial sustainability as well as the overall efficacy of the care model is apparent. Recent seminal resources in Geriatric EDs include the Geriatric Emergency Department Collaborative, the Geriatric Emergency Care Applied Research Network, and the Geriatric Emergency Department Accreditation program. Attention to workforce education and specific care process/protocols for screening/assessment, cognitive dysfunction and falls is growing. Overall findings support the effectiveness and potential of Geriatric EDs in enhancing emergency care for older adults.
Summary
A review providing an overview of current themes and future directions of Geriatric EDs through a thematic analysis of the current literature. Key Geriatric ED themes include four “calls for action”, assessment of the model’s financial sustainability, an examination of the model’s efficacy and quality, and an identification of key resources foundational to Geriatric EDs. Targeted Geriatric ED workforce education programs and attention to care processes are contributing to improving outcomes for older adult in the ED.
