Sleep Disturbance in Older Adults in the Emergency Department: Prevalence, Predictors and Outcomes Comparing Frail and Non-frail Patients (360G-Wellcome-211498_Z_18_Z)

The overall aim of this study is to show the impact of poor sleep at baseline and in particular during ED overnight stay on older adults comparing the effects on those identifed as frail or non-frail (robust). The specific objectives are to: (1) Examine the prevalence of pre-existing sleep impairment using a validated sleep measure, (2) Investigate which independent variables are associated with poor sleep in an ED including individual objective (demographics, existing sleep problems, admission diagnosis, Barthel Index ADL score, 4AT delirium score, co-morbidities and polypharmacy including use of hypnotics), subjective (percieved sleep quality and quality of life) environmental (noise levels) and logistical (triage score, total duration boarding in ED, location of trolley in ED) factors. (3) Evaluate the impact of sleep disturbance (baseline and overnight) in the ED on patient satisfaction and adverse healthcare outcomes (including LOS, 30 day-mortality and 30-day redmission rates, need for rehabilitation) adjusting for individual factors, in an older cohort of patients (aged > 70) admitted through the ED of a large Irish university teaching hospital (UHG).
