Show moreOlder emergency department (ED) patients are at high risk of adverse health outcomes, such as mortality or functional decline. Early identification of those patients who are at highest risk gives an opportunity to target interventions and guide treatment decisions for those who need it most.This thesis describes the clinical value of using geriatric screening in the ED. Geriatric screening identifies older patients at high risk of both short- and long-term poor outcomes and provides valuable information for care providers treating acutely hospitalized older patients. The results from screening could aid in individualized treatment decisions to acquire more personalized care, and therefore gives an opportunity to optimize outcomes for older patients.Implementation of screening programs in the fast-paced environment of everyday ED practice remains scarce. The results of this thesis show that the implementation of a geriatric screening program in routine ED practice is feasible and the use of screening is accepted by both the users (triage nurses) and the older patients.Using geriatric screening in routine care is therefore useful and feasible. More research will be needed to investigate implementation in different hospitals to generate guidance on how geriatric screening tools can be successfully implemented on a wide scale. Show less
