At handover, a patient is described as “very quiet today”. Yesterday, they asked questions and chatted with relatives. This morning, they barely answer, leave breakfast untouched and seem unable to follow a conversation. In this fictional scenario, quietness should prompt a closer assessment. A patient does not have to shout, pull at a cannula or attempt to leave the ward before a change in mental state deserves attention.

Recognise a change from the patient’s usual state

Delirium can develop over hours or days and fluctuate. Watch for new inattention, disorientation, altered communication or hallucinations. Hypoactive delirium can appear as withdrawal, sleepiness, slower responses, reduced movement or appetite. Older age, cognitive impairment, severe illness and hip fracture increase risk. Ask someone who knows the patient what has changed; an established dementia diagnosis does not explain away a new deterioration. NICE guidance.

Sudden confusion needs urgent assessment

Sudden confusion may reflect serious illness. Seek urgent clinical help and use your facility’s deterioration or emergency-response pathway; do not wait for the next routine ward round. Possible causes include infection, stroke, hypoglycaemia, head injury, medicines, alcohol withdrawal and cardiopulmonary illness. Do not assume the cause from behaviour alone. While help is coming, stay with the person, speak in short, calm sentences and explain who you are and where they are. Avoid overwhelming them with repeated questions. NHS: sudden confusion.

Use a screening tool without delaying care

Where indicators are present, NICE recommends assessment with the 4AT by a competent practitioner. In critical care or postoperative recovery, use CAM-ICU or ICDSC instead. A suitably experienced clinician makes the final diagnosis. Document changes and communicate them promptly. Treatment addresses the underlying cause or causes; reassurance and reorientation remain part of care. For distress, try appropriate verbal and non-verbal de-escalation first. Assessment and management recommendations.

Look beyond the label “confused”

Infection, dehydration, constipation, pain and medication reactions can contribute. Delirium may vary during the day, with periods when the patient seems more like their usual self. Calm, patient communication and familiar objects can help support the person while the clinical team investigates and treats the cause. Sherwood Forest Hospitals: delirium information.

A clearer nursing handover

Fictional learning example: “I am concerned about a new change in Patient A’s mental state. Their daughter says they were conversing normally yesterday. Since this morning they have struggled to follow questions and are unusually withdrawn. I have started our assessment and escalation pathway. Please review them urgently.”

In a real handover, identify the patient using approved identifiers and add the actual observation results, assessment findings, time of onset, relevant medicines, actions already taken and the response to those actions. Never invent observations to complete a template. Record whom you contacted, when they responded and the agreed next step. A useful record allows the next nurse to understand what changed and what remains outstanding.

One question for your next shift

When you hear “the patient is quiet”, ask: “Is this usual for them, or is it a new change?” That question can turn a vague description into a meaningful clinical concern.
