heart rate, blood pressure, body temperature, respiration rate, peripheral capillary haemoglobin oxygen saturation)

Patients are asked how they assess their own mobility: - Stable walking without aids or limited mobility with aids (walking aid, wheelchair, lying down).

Assessment of level of consciousness by AVPUC scale (alert, new confusion, verbal, pain, unresponsive, new confusion)

Questionnaire with a predefined list of 37 symptoms

Patients over the age of 65 are asked the following: "generally asked: what matters most to you at the moment?" and "why is that important for you?".

Questionnaire consisting of 10 questions about the decision-making processes in the emergency department and the factors that form the basis of their decisions regarding the diagnosis, treatment, and disposition of the patient.

The NRS is a segmented numeric version of the visual analog scale (VAS) in which a respondent selects a whole number (0-10 integers) that best reflects the intensity of his/her pain ('0' representing one pain extreme (e.g. "no pain") to '10' representing the other pain extreme (e.g. "pain as bad as you can imagine"))

The CFS is a commonly used score to assess frailty. It was developed within the Canadian Study of Health and Aging and consists of a 9-level ordinal scale ranging from very fit (score 1) to living with very severe frailty (score 8), and score 9 reserved for those who are terminally ill.

The PPI is derived from the photoplethysmography signal of pulse oximetry and represents the ratio between the pulsatile component (arterial compartment) and the non-pulsatile component (non-arterial tissues) of the light detected by the sensor. PPI can provide information for resuscitation in shock, outcome prediction in critically ill patients and may serve as an adjunct triage tool.

CRT provides a standardized assessment of capillary flow dynamics and is most assessed at the fingertip in clinical practice. A prolonged CRT in patients with septic, traumatic and cardiogenic shock has been associated with increased mortality and might be used as a resuscitation target in patients with septic shock.

Mattling is a characteristic discoloration of the skin resulting from reduced skin blood flow and has been shown to be associated with tissue hypoperfusion. The MS provides a simple scale (0-5) to characterize the extent of skin mottling around the knee and the severity of mottling is associated with adverse outcomes.

Mental health complaints require safe, efficient risk stratification to distinguish primary psychiatric conditions from medical causes or comorbidities. Because current medical screening practices are inconsistent and unvalidated, this study will use prospective routine ED data to evaluate triage assessments of psychiatric likelihood and identify opportunities for standardized, evidence-based screening.

Delirium is a common and high-risk condition in older ED patients, and early detection is crucial to improve short- and long-term outcomes. This study will use routinely collected ED screening data (modified Confusion Assessment Method for the Emergency Department (mCAM-ED) and the four-item Abbreviated Mental Test (AMT-4)) to describe delirium prevalence and evaluate delirium identification in the emergency setting.
