Mental Health Emergencies in Pre-Hospital Care

Mental Health Emergencies in Pre-Hospital Care

Mental health emergencies are among the most challenging and emotionally demanding calls a paramedic will attend. In the UK, mental health-related incidents now account for a significant proportion of ambulance service demand, with crews frequently attending patients in acute psychological crisis, those who have self-harmed, or individuals experiencing a first episode of severe mental illness. Understanding how to approach these calls safely, compassionately, and within your legal framework is essential for any student paramedic entering clinical practice.

Understanding the Scope of Mental Health Calls

Pre-hospital mental health emergencies are not a single entity. They encompass a wide range of presentations, including:

• Acute suicidal ideation or attempts
• Self-harm with or without medical injury
• Psychosis and first-episode psychosis
• Severe anxiety and panic disorders
• Acute behavioural disturbance
• Mental health crisis linked to substance misuse
• Delirium (which may be mistaken for psychiatric illness)

A critical early skill is distinguishing between a primary psychiatric emergency and an underlying organic cause. Conditions such as hypoglycaemia, hypoxia, head injury, encephalitis, and substance intoxication or withdrawal can all mimic acute mental illness. Always complete a thorough physical assessment before attributing symptoms to a psychiatric cause.

The Initial Approach: Scene Safety and Communication

Your approach to a mental health call begins before you reach the patient. Consider scene safety carefully — particularly for calls involving self-harm, weapons, or agitated individuals. Liaise with police where appropriate, and never enter an unsafe environment alone.

When you reach the patient, your communication style matters enormously. Key principles include:

• Use a calm, non-threatening tone — avoid raised voices or authoritative commands unless safety demands it
• Introduce yourself clearly and explain your role
• Use open questions — "Can you tell me what's been happening today?" rather than closed interrogative questioning
• Validate their experience — acknowledge their distress without dismissing or minimising it
• Avoid arguing about perceived reality — particularly in psychosis
• Give the patient as much control as possible — involve them in decisions about their care

Trauma-informed care is increasingly embedded in NHS ambulance service practice. Approaching every patient with the assumption that they may have a history of trauma, and adapting your communication accordingly, is both ethically sound and clinically effective.

Assessing Mental State in the Pre-Hospital Environment

A structured mental state examination (MSE) is a core clinical skill. While the full psychiatric MSE used in hospital settings is not always feasible in pre-hospital care, paramedics should be able to assess and document:

• Appearance and behaviour — self-care, agitation, psychomotor changes
• Speech — rate, volume, coherence
• Mood and affect — subjective and objective mood, appropriateness
• Thought content — presence of suicidal or homicidal ideation, delusions
• Perception — hallucinations (auditory, visual, tactile)
• Cognition — orientation, memory, concentration
• Insight — does the patient recognise they are unwell?

Risk assessment is a core component. Ask directly and sensitively about suicidal intent — asking does not increase risk and allows you to understand the severity of the situation. Document your findings clearly; this information is vital for handover to receiving mental health teams or emergency departments.

Legal Framework: Mental Capacity and the Mental Health Act

UK paramedics practise within a specific legal framework when managing mental health emergencies. The two key pieces of legislation are:

Mental Capacity Act 2005 (MCA)

The MCA applies to all adults and assumes capacity unless assessed otherwise. Capacity is decision-specific and time-specific. To assess capacity, you must establish whether the patient can: understand the information, retain it, weigh it up, and communicate a decision. A patient refusing treatment or transport may have capacity to do so, even if that decision seems unwise to you.

Mental Health Act 1983 (MHA) — Section 136

Section 136 of the MHA gives police the power to remove a person from a public place to a place of safety if they appear to have a mental disorder and are in immediate need of care or control. Since the 2017 amendments, police can also use this power in private dwellings in certain circumstances, and ambulances can be designated as places of safety. As a paramedic, you will frequently work alongside police on Section 136 detentions, and understanding your role — including your duty of care and the importance of maintaining patient dignity — is essential.

Acute Behavioural Disturbance and Chemical Sedation

Excited delirium and acute behavioural disturbance present significant risk to both the patient and attending crew. JRCALC guidelines provide a framework for managing these presentations, including criteria for the use of chemical sedation. Paramedics with the appropriate scope of practice may administer medications such as midazolam or ketamine in line with local protocols. Post-sedation monitoring is critical — maintain airway patency, monitor SpO2, respiratory rate, and level of consciousness continuously.

Pathways and Handover

Destination decisions for mental health patients can be complex. Not every mental health crisis requires an emergency department attendance. Many UK ambulance services now have mental health crisis pathways, including direct referral to NHS mental health crisis teams, liaison psychiatry services, or street triage schemes. Familiarise yourself with your local Integrated Care System's pathways, as these vary by region.

When handing over to any receiving service, use a structured tool such as SBAR (Situation, Background, Assessment, Recommendation) and ensure your documentation captures the patient's mental state, capacity assessment, any risk factors identified, and the treatment provided.

Looking After Yourself

Mental health calls can be emotionally exhausting. Repeated exposure to suicide attempts, self-harm, and profound human distress takes a toll. Seeking regular clinical supervision, debriefing after difficult calls, and accessing occupational health or peer support programmes is not a sign of weakness — it is part of sustainable professional practice.
