Background Older adult delirium is often unrecognized in the emergency department (ED), yet the most compelling research questions to overcome knowledge‐to‐practice deficits remain undefined. The Geriatric Emergency care Applied Research (GEAR) Network was organized to identify and prioritize delirium clinical questions. Methods GEAR identified and engaged 49 transdisciplinary stakeholders including emergency physicians, geriatricians, nurses, social workers, pharmacists, and patient advocates. Adhering to Preferred Reporting Items for Systematic Reviews and Meta‐Analyses for Scoping Reviews, clinical questions were derived, medical librarian electronic searches were conducted, and applicable research evidence was synthesized for ED delirium detection, prevention, and management. The scoping review served as the foundation for a consensus conference to identify the highest priority research foci. Results In the scoping review, 27 delirium detection “instruments” were described in 48 ED studies and used variable criterion standards with the result of delirium prevalence ranging from 6% to 38%. Clinician gestalt was the most common “instrument” evaluated with sensitivity ranging from 0% to 81% and specificity from 65% to 100%. For delirium management, 15 relevant studies were identified, including one randomized controlled trial. Some intervention studies targeted clinicians via education and others used clinical pathways. Three medications were evaluated to reduce or prevent ED delirium. No intervention consistently prevented or treated delirium. After reviewing the scoping review results, the GEAR stakeholders identified ED delirium prevention interventions not reliant on additional nurse or physician effort as the highest priority research. Conclusions Transdisciplinary stakeholders prioritize ED delirium prevention studies that are not reliant on health care worker tasks instead of alternative research directions such as defining etiologic delirium phenotypes to target prevention or intervention strategies.

Low-income older adults are particularly vulnerable during care transitions. The present study evaluated the effectiveness of a transitional care model in this population. A quasi-experimental design was used to compare outcomes in the intervention group with historical controls at 30, 90, 180, and 365 days after discharge, along with a pre-postintervention evaluation of the intervention group. Eligible individuals were age 60 and older hospitalized between June 2008 and January 2009. Main outcome measures were readmissions, emergency department (ED) visits, and primary care services use. Of 121 participants, 55% were female and 90% African American, with a mean age of 69. Readmission rates were generally but not significantly lower in the intervention group than in controls (Day 30, 9.6% vs 17.3%; Day 90, 28.9% vs 25.0%; Day 180, 32.7% vs 36.5%; Day 365, 44.2% vs 53.9%; P > .05), as were ED visit rates (Day 30, 17.3% vs 15.4%; Day 90, 32.7% vs 34.6%; Day 180, 38.5% vs 40.4%; Day 365, 50.0% vs 55.8%; P > .05). Primary care service utilization rates were significantly higher in the intervention group than in controls at Day 30 (40.4% vs 19.2%, P < .001), 90 (74.9% vs 32.7%, P < .001), and 180 (65.4% vs 32.7%, P < .001). The lack of statistically significant reduction in readmissions and ED visits with the intervention, may suggest the need for additional assistance during care transitions for this vulnerable population.
