While prolonged ED stays are associated with increased delirium and mortality, the effect of placement in hallways remains unknown. This study's objective was to assess whether prolonged ED hallway exposure is associated with incident delirium and severe agitation in older adults and older persons living with dementia (PLWD).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>We conducted a multi\u2010site retrospective cohort database study between January 1, 2022 and December 31, 2023 of older adults (age 65+) without prevalent delirium admitted to a general medicine service with an ED stay &gt;\u20098\u2009h. Patients were dichotomized into two groups: &gt;\u20098 or &lt;\u20098\u2009h of care in ED hallways. Our primary outcome was incident delirium and severe agitation (a composite outcome of ICD\u201010 code for delirium, positive nursing screen, use of parenteral antipsychotics, and\/or physical restraints) after admission request. Secondary outcomes included hospital length of stay, inpatient and 30\u2010day mortality, and 30\u2010day ED revisit and readmission. We employed mixed\u2010effect logistic regression models, independent of and mediated by history of dementia and adjusted for additional confounders.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Our sample included 11,105 patients (median age 77, 51% female), with 2299 in the hallway group and 8806 in the non\u2010hallway group. Prolonged ED hallway exposure was not associated with delirium and severe agitation for our general geriatric cohort (OR 0.87 [0.53\u20131.42]) but was for PLWD (OR 1.48 [1.03\u20132.13]). We observed no association between hallway care and our secondary outcomes except that the hallway group was associated with lower 30\u2010day readmission (OR 0.69 [0.52\u20130.92]).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Prolonged ED hallway care was not associated with delirium and severe agitation in a general geriatric cohort but was for older PLWD.
