Credible immediate danger

A specific threat, weapon access, escalating assault, severe agitation, an unsafe dependent or current abuse requires urgent environmental and safeguarding action before a routine assessment continues.

Action: Create distance and a safe exit, summon appropriately trained help, separate potential victims and perpetrators when safe, and use emergency services if the setting cannot contain the danger. Treat intoxication or physical illness, share the minimum necessary information with those able to reduce serious harm and document capacity, legal authority and proportionality.

Purpose and principles

Formulate risks of harm by, to and around the person through specific scenarios, history, dynamic factors, safeguarding and environmental evidence, then use proportionate prevention without stereotyping mental illness or overlooking victimisation and self-neglect.

Violence is not explained by diagnosis alone. Establish previous behaviour from the patient, records and collateral sources: what occurred, to whom, in what setting, with what weapon or injury, under which symptoms or substances, and how it ended. Distinguish remote, isolated events from a recent escalating pattern. Explore current grievance, intent, target access, planning, rehearsal and capability. Ask about protective factors such as voluntary distance, treatment engagement and trusted support, testing whether they operate in the proposed scenario.

Formulate dynamic mechanisms. Persecutory belief may focus attention on a named neighbour; alcohol may reduce inhibition; eviction may increase contact; weapon availability may increase lethality. Each link suggests an intervention. Also assess medical and neurological contributors to agitation, including delirium, pain, intoxication, withdrawal, head injury and adverse medicine effects. Use de-escalation and trauma-informed communication, preserving personal space, clear exits and calm explanation. Restriction must be necessary, proportionate and reviewed.

Indications, selection and cautions

Targeted violence scenario

A grievance, named person, route of access, available means and recent rehearsal creates a concrete pathway requiring immediate disruption.

Dynamic escalation

Intoxication, insomnia, acute symptoms, humiliation, treatment loss or impending contact is increasing the likelihood or potential severity of harm.

Coercive exploitation

Another person controls money, accommodation, communication, substances, sex or treatment and the patient cannot safely exercise ordinary choices.

Severe self-neglect

Essential nutrition, health, hygiene or environmental safety has deteriorated enough to create serious harm and possible adult-safeguarding duties.

Mixed direction of harm

The person can be threatened, exploited and reactive while also posing danger, requiring separate formulations and protections for each pathway.

Red flags requiring action

  • A named target, recent surveillance, weapon access, rehearsal, command hallucinations or rapidly escalating grievance makes a violence scenario more concrete and urgent.
  • Intoxication, withdrawal, acute psychosis, mania, head injury, delirium, sleep deprivation and recent non-adherence can change risk rapidly and require cause-specific treatment.
  • Unexplained injury, fear of a companion, restricted money or communication, sexual exploitation, trafficking or forced medicine use may indicate that the patient is a victim rather than a perpetrator.

Method and interpretation

  1. 01
    Behavioural and forensic chronologyFirst step
    Why
    Define past acts, targets, context, severity, legal outcomes, triggers and previous successful prevention.
    Interpretation and limitations
    Recent similar behaviour has greater scenario relevance than a remote unrelated event. Records may contain bias and require source checking.
  2. 02
    Current intent and means assessment
    Why
    Clarify grievance, target, planning, weapon access, stalking, arson, sexual harm and voluntary distance.
    Interpretation and limitations
    Specificity and opportunity alter urgency, but disclosure can be incomplete; combine interview with behaviour, collateral evidence and environmental facts.
  3. 03
    Dynamic clinical assessment
    Why
    Identify psychosis, mood activation, cognition, substances, withdrawal, pain, sleep and treatment disruption.
    Interpretation and limitations
    Treatable drivers suggest interventions but do not make violence inevitable. Reassess after sobriety, symptom treatment and environmental change.
  4. 04
    Vulnerability and safeguarding enquiry
    Why
    Detect abuse, exploitation, trafficking, financial control, neglect and risk to children or dependent adults.
    Interpretation and limitations
    Interview privately and assess decision-specific capacity, coercion and immediate danger. Use the jurisdiction's statutory safeguarding pathway.

  1. 1Secure exits, summon trained support, separate potential victim and aggressor where safe and remove accessible means without provocative confrontation.
  2. 2Assess physiology, intoxication, mental state, target, intent, plan and capability while activating emergency or police support when required.

Risks, monitoring and follow-up

  • Reassess scenarios after intoxication resolves, symptoms change, a target becomes accessible, housing changes or a significant court or relationship event occurs.
  • Review whether separation, means control, treatment, safeguarding and accommodation actions actually occurred rather than assuming referral equals protection.
  • Track victim fear, contact attempts, stalking behaviour, weapon access and breaches of agreed boundaries using verified information where possible.
  • Review carer and staff safety plans without excluding the patient from transparent discussion unless disclosure would itself increase danger.
  • Document de-escalation, restraint, police involvement and injury, then debrief and revise prevention plans after each serious incident.

Special situations

Diagnosis is not destiny

Most people with mental illness are not violent, and formulation should focus on individual behaviour, context and modifiable pathways rather than stereotypes.

Victim and perpetrator coexist

A patient may use violence while also experiencing coercion or exploitation, so each direction of harm needs its own evidence and intervention.

Specificity drives action

A named target, route of contact and weapon suggests different protection from diffuse angry thoughts without intent or opportunity.

Self-neglect is multifactorial

Capacity, executive function, poverty, physical disability, hoarding, coercion and service refusal can combine and require different legal and practical responses.

Tools support judgement

Structured methods can improve consistency in specialist settings but cannot supply current facts, cultural context or an individual management plan.

Common pitfalls

  1. 01

    Inferring violence risk from psychiatric diagnosis, ethnicity, homelessness or appearance alone.

  2. 02

    Assessing only harm by the patient and missing exploitation, abuse or hate crime against them.

  3. 03

    Using a global risk category without naming target, scenario, trigger, means and intervention.

  4. 04

    Letting a structured tool replace interview, collateral evidence and dynamic reassessment.

  5. 05

    Interviewing about domestic abuse through the accompanying partner or family interpreter.

  6. 06

    Assuming refusal of support proves capacity or removes adult-safeguarding concern.

  7. 07

    Sharing the entire record when a limited factual disclosure would address the serious danger.

Authoring stateComplete draftClinical stateAwaiting reviewJurisdictionUnited Kingdom
Assess risk to the person with equal seriousness. People with severe mental illness may experience domestic abuse, exploitation, hate crime, financial control, trafficking and neglect. Speak privately with a professional interpreter rather than a controlling companion. Ask who controls money, housing, medicines, telephone, sex, work and travel; look for fear, inconsistent access and unexplained injuries. A person may both cause and experience harm. Avoid forcing a binary victim-perpetrator label when relationships are complex.

Self-neglect includes inability or refusal to meet essential care, health, hygiene, nutrition, accommodation or safety needs. Determine capacity for the specific decisions, underlying mental or physical illness, executive ability, coercion and the seriousness of consequences. In England, the Care Act adult-safeguarding criteria depend on needs for care and support, experience or risk of abuse or neglect, and inability to protect because of those needs. Wales, Scotland and Northern Ireland use different legislation and procedures, so follow the current local pathway.

Information sharing follows purpose. Seek consent where practicable, but GMC guidance permits disclosure when required by law or justified in the public interest to protect someone from death or serious harm. Share relevant facts with the agency able to act, not the entire history by default. Consider warning or protecting an identifiable potential victim with senior, safeguarding, police or legal advice. Document the evidence, alternatives, recipient, content, whether the person was informed and why the decision was proportionate.

Key points

  • Assess harm to others, harm from others, self-neglect, exploitation, safeguarding of dependants and environmental hazards as related but distinct scenarios.
  • Start with actual behaviour: previous violence, pattern, context, severity, targets, triggers, access to means, consequences and what previously stopped escalation.
  • Ask directly about current thoughts, grievances, named people, intent, planning, weapons, stalking, arson, sexual violence and ability to maintain distance.
  • Identify dynamic drivers including symptoms, substances, pain, humiliation, housing, relationship conflict, peer influence, treatment disruption and anticipated events.
  • Obtain collateral and records with consent where possible; urgent serious-harm or safeguarding information may justify proportionate sharing without consent.
  • Use structured professional judgement where the service supports it, but do not let a tool replace formulation, current examination or individual context.
  • Include vulnerability and victimisation: coercive control, county lines, cuckooing, financial abuse, hate crime, neglect and inability to protect oneself.
  • Match interventions to the pathway through de-escalation, separation, means control, substance treatment, safeguarding, accommodation, victim support and clinical care.
  • Record the specific feared event, timeframe, potential victim, warning signs, actions, information sharing and review owner instead of a global risk label.
  • Malnutrition, untreated illness, unsafe housing, fire risk, medication omission or inability to seek help can constitute serious self-neglect even without overt suicidal intent.
  • A psychiatric diagnosis, ethnicity, homelessness or previous detention must not substitute for behavioural evidence or justify blanket coercion.

    Scenario-based risk formulation
    Why
    Connect a feared event to trigger, target, means, timing, warning signs and interruption points.
    Interpretation and limitations
    Record separate formulations for different harms and name responsible actions; a single high-risk label lacks operational detail.
    • 2
    Define the most plausible victim, event, timeframe and warning signs and identify factors that reduce or increase each link.
  • 3Assign interventions for clinical drivers, means, contact, accommodation, substance use and victim protection with named ownership.
    • 03Vulnerability responseCreate private space and safeguardAbuse, exploitation, self-neglect or risk to a dependent person is suspected.+
    1. 1Speak privately with communication support, assess immediate safety, specific decisions, coercion, essential needs and people exposed to harm.
    2. 2Seek consent for referral where possible and use the relevant statutory or public-interest route when serious harm requires action without it.
    3. 3Agree safe contact, accommodation and follow-up arrangements that do not reveal information to a suspected perpetrator.
