“…Collectively, the indicators of acute deterioration described in ED-based research, closely resemble the de nition of an acute deterioration in the RAC population namely; "a sudden, clinically important deviation from the persons baseline cognitive, behavioural, functional or physical domains ... that without intervention, may result in complications or death. "(28) Speci cally ED research names these indicators as, loss of consciousness, altered mental status, speech disorders, dizziness (cognitive domain), not eating and drinking (behavioural domain), functional decline, mobility changes and falls (functional domain) new urinary incontinence, weakness, fatigue, dyspnoea (physical domain) (17,20,26,29) These are consistent with RAC reports that clinical indicators of acute deterioration are unresponsiveness, altered mental status, behavior change, reduced food or uid intake, functional decline, falls, continence changes, fatigue, dyspnoea, uncontrolled pain, nausea and vomiting and vital sign abnormalities (9,18,19,30).…”
