Emergency Department Hallways Are Associated With Incident Delirium and Severe Agitation in Older Adults Living With Dementia

Topic: Risk, prevention and care in population studies
Our sample included 11,105 patients (median age 77, 51% female), with 2299 in the hallway group and 8806 in the non-hallway group. Prolonged ED hallway exposure was not associated with delirium and severe agitation for our general geriatric cohort (OR 0.87 [0.53-1.42]) but was for PLWD (OR 1.48 [1.03-2.13]). We observed no association between hallway care and our secondary outcomes except that the hallway group was associated with lower 30-day readmission (OR 0.69 [0.52-0.92]). Prolonged ED hallway care was not associated with delirium and severe agitation in a general geriatric cohort but was for older PLWD. Prospective research is needed to determine if hospitals should consider prioritizing PLWD for rooms.
Key findings
- Our sample included 11,105 patients (median age 77, 51% female), with 2299 in the hallway group and 8806 in the non-hallway group.
- Prolonged ED hallway exposure was not associated with delirium and severe agitation for our general geriatric cohort (OR 0.87 [0.53-1.42]) but was for PLWD (OR 1.48 [1.03-2.13]).
- We observed no association between hallway care and our secondary outcomes except that the hallway group was associated with lower 30-day readmission (OR 0.69 [0.52-0.92]).
- Prolonged ED hallway care was not associated with delirium and severe agitation in a general geriatric cohort but was for older PLWD.
- Prospective research is needed to determine if hospitals should consider prioritizing PLWD for rooms.
Why it matters
In this retrospective cohort, prolonged emergency department hallway care was linked to delirium and severe agitation in older adults living with dementia, though not in the general older group. It suggests hospitals might prioritise people with dementia for rooms, but prospective research is needed and this is not a treatment or cure.
