Background:~Older people visit the Emergency Department (ED) more frequently then younger people and have a higher risk of functional decline, ED revisit or death. Several screening tools (such as the Dutch safety management system (VMS) and Acutely Presenting Older Patient (APOP)) have been developed to identify patients at the highest risk of adverse outcomes. Almost all require adequate communication with the patient, which is not always possible, for example when elderly patients present with a delirium. Point of Care Ultrasonography (POCUS) may be a valuable alternative screening tool in these instances.~Main research question:~To identify whether POCUS measurement of the rectus femoris muscle cross-sectional area (Qcsa) can be used as an alternative screening tool to predict functional decline, ED revisit or death in elderly patients in the ED.~Design (including population, confounders/outcomes):~This is a single centre prospective trial. Patients >70 years and older presenting in the ED of the University Medical Centre Groningen (UMCG) who are participating in the Acutelines bio-databank are eligible for inclusion. 68 patients will be included. Data will be extracted from the Acutelines bio-databank. A trained physician will perform ultrasound measurements in a standardized way.~Expected results:~The aim of this study is to evaluate whether ultrasound measurements of the Qcsa can be utilized to identify older patients who are at risk for functional decline, ED revisit or death.
