What symptom should be present for ESC to consider the patient as "high-risk"?

Delusions or hallucinations are considered significant indicators of high-risk status in patients when evaluating for emergency situations. These symptoms suggest a possible underlying psychiatric condition or severe medical issue affecting the brain, such as a delirium or a severe psychotic episode. The presence of these symptoms typically indicates that a patient may be at risk for harm, whether to themselves or others. It can complicate their ability to make rational decisions and respond to medical care effectively, which is why it is crucial for emergency service providers to recognize these signs.

The other options—low energy levels, confusion without distress, and stable cognitive function—do not carry the same immediate implications for high-risk medical or psychiatric emergencies. Low energy levels may be indicative of several conditions but do not suggest an acute high risk. Confusion without distress may suggest a cognitive issue but not necessarily an immediate threat to the patient's safety or the need for acute intervention. Stable cognitive function indicates that the patient is not experiencing significant mental distress or impairment, which clearly does not categorize them as high risk.
