# Suicide Risk Assessment

Suicide assessment is a repeated, collaborative clinical process that identifies current ideation, intent, planning, access to lethal means, prior behavior, drivers, and protective factors to determine immediate safety actions, treatment needs, and follow-up rather than to assign a static risk category.

**Clinical question:** How should clinicians assess acute and longitudinal suicide risk and translate findings into safe disposition and management?

## What matters in practice
- Ask directly about suicidal ideation and intent; assess past self-harm, its frequency and medical seriousness, and use of violent methods. [24]
- Do not use a screening score, prediction model, or global low-medium-high label as the sole basis for treatment, discharge, or prediction of future suicide or recurrent self-harm. [23]
- A positive screen requires a clinically meaningful assessment of ideation, intent, plan, access to lethal means, prior suicidal behavior, acute precipitants, and available supports. [5][20]
- Risk assessment is longitudinal: document the formulation and reassess when clinical state, setting, treatment, or access to lethal means changes. [5][9]
- When prescribing for a patient who has self-harmed or may self-harm, account for overdose toxicity and access to medicines, including opioid-containing analgesics and tricyclic antidepressants. [23]

## Treat suicide risk assessment as formulation and management, not prediction

The actionable question is what must change now to reduce imminent danger and sustain follow-up.

Suicide is a behavior rather than a diagnosis, and suicidal thoughts may occur with or without a mental illness. Individual suicide cannot be predicted accurately at a single time point; assessment therefore should drive a collaborative safety and treatment plan rather than a claim of certainty. [5]

Screening tools can identify patients requiring further assessment, but their classification performance depends on the selected threshold and no universal threshold is appropriate across clinical settings. Clinical context determines the relative consequences of false-positive and false-negative decisions. [1]

Document the patient’s current presentation, longitudinal vulnerabilities, dynamic drivers, mitigating factors, clinical judgment, and specific actions taken. Repeat assessment during the clinical course rather than relying on a baseline designation. [9]
- Avoid premature reassurance based on denial of current intent alone; integrate current ideation with behavior history, planning, means access, acute stressors, and ability to engage in a safety plan. [5][20]
- Avoid using a global category such as “low risk” as a disposition decision. NICE specifically recommends against global low-medium-high stratification to predict suicide or recurrent self-harm or to determine treatment and discharge. [23]
- Use validated screening and structured assessment to improve consistency, but retain individualized clinical formulation and responsibility for disposition. The 2024 VA/DoD guideline recognizes validated screening as part of routine care while noting that outcome effects of prediction models remain uncertain. [6]

*Assessment domains that should inform an individualized suicide risk formulation rather than a score-based disposition decision. [5][20][23]*

| Domain | What to establish | Clinical consequence |
| --- | --- | --- |
| Current suicidality | Presence, frequency, and trajectory of suicidal thoughts; intent; plan; and preparatory behavior. [5][20] | Determines urgency of containment, psychiatric evaluation, and capacity for outpatient safety planning. [5][20] |
| Lethal means | Access to the method contemplated and ability to reduce or transfer access. [5] | Means access is an immediate modifiable target in the safety plan and disposition decision. [5] |
| Prior behavior | Past suicide attempts and self-harm, including frequency, medical seriousness, and violent methods. [24] | Past behavior materially informs baseline vulnerability and the needed intensity of monitoring and follow-up. [24] |
| Acute drivers and supports | Mental illness, life crisis, substance use, interpersonal circumstances, ambivalence, and available supports. [5] | Identifies treatable precipitants, required collateral involvement, and whether a credible outpatient plan is feasible. [5] |
| Engagement and follow-through | Ability to participate in assessment, accept help, adhere to the immediate plan, and access timely care. [5][9] | Determines whether outpatient management can be made sufficiently safe or whether a more protected setting is needed. [5][9] |

## Screen broadly when indicated, then perform a focused clinical assessment

A screen identifies the need for assessment; it does not establish disposition.

General medical settings are important detection sites. A cited systematic review found that, on average, 80% of people who died by suicide had primary care contact within the preceding year and 44% within the preceding month, compared with 31% who had mental health care contact in the preceding year. [10]

For adolescents, the American Academy of Pediatrics recommends universal screening from age 12 years during preventive health care and screening at ages 8 to 11 years when clinically indicated. [10] In the ASQ assessment framework, follow-up evaluation includes suicidal-thought frequency, presence of a suicide plan, and past suicidal behavior. [20]

Ask directly about suicidal ideation and intent. In patients with self-harm, establish the history and frequency of prior self-harm, medical seriousness, and use of violent methods. [24] Obtain collateral information when needed for immediate safety and permitted by applicable privacy and emergency exceptions.
- Clarify whether the patient is describing passive death wishes, active suicidal ideation, intent to act, a specific plan, preparatory behavior, or a recent attempt; these are clinically distinct phenomena. [5][20]
- Ask about access to the planned or likely method, including medications, firearms, and other lethal means. [5]
- Assess co-occurring mental illness and life crisis without assuming either is required for suicide risk. [5]
- Evaluate acute intoxication, delirium, psychosis, severe agitation, or impaired capacity as factors that can limit reliability of interview and ability to engage in an outpatient plan; the supplied sources do not provide validated numeric thresholds for disposition.

### Use tools as adjuncts, not gatekeepers

Risk tools and prediction models may support standardized detection and structured questioning, but evidence does not support using them alone to predict an individual’s future suicide or repeat self-harm. [1][6][23]
- Do not use a score or scale to decide who receives treatment or who may be discharged. [23]
- Do not convert a dynamic formulation into a fixed global risk label. [23]
- If a model is used, document the clinical context and the management action it triggers; threshold choice reflects the harms and benefits of misclassification. [1]

*Role of structured approaches in suicide care. [1][6][23]*

| Approach | Appropriate use | Inappropriate use |
| --- | --- | --- |
| Validated screening instrument | Routine detection and identification of patients needing a more complete assessment. [6] | Treating a negative or positive result as a complete individualized risk formulation. [6] |
| Structured clinical assessment | Eliciting ideation, plan, intent, prior behavior, means access, drivers, and protective factors. [5][20] | Replacing clinical judgment about current safety, capacity, supports, and disposition. [5] |
| Prediction model or score | Potential decision support when paired with a defined clinical pathway and context-specific threshold. [1] | Solely predicting suicide, withholding treatment, or authorizing discharge. [23] |

## Match disposition to current danger, modifiable access, and ability to execute a safe plan

Management begins during assessment and should address both physical and psychiatric needs concurrently.

For a patient with current suicidal intent, a feasible plan, access to lethal means, recent serious suicidal behavior, or inability to participate reliably in safety planning, prioritize immediate protection, urgent psychiatric evaluation, and a setting capable of continuous observation and escalation. This is a clinical synthesis of the assessment domains emphasized in the cited sources; the supplied results do not provide a validated single threshold for hospitalization. [5][20][24]

In self-harm presentations, physical and mental health care should proceed concurrently whenever possible so that one need does not delay the other. Clear care pathways and communication between teams support safeguarding and de-escalation in emergency settings. [22]

For patients managed outside a protected setting, document why outpatient care is feasible, the patient’s and supports’ roles, immediate steps to reduce lethal-means access, the crisis response plan, and concrete follow-up arrangements. Assessment and management are ongoing processes, including during transitions of care. [5][9]
- Do not discharge on the basis of a favorable score, a global “low-risk” designation, or completion of a checklist. [23]
- Address access to lethal means explicitly as part of the immediate management plan. [5]
- Engage family members or carers and share information as appropriate; support and information for patients and carers are recommended in self-harm care. [23]
- Communicate a specific return pathway for worsening suicidal thoughts, intent, inability to follow the plan, or renewed means access; the supplied evidence does not specify a universal follow-up interval.

### Medication safety in patients at risk of self-harm

No medication regimen, dose, or rapid anti-suicidal pharmacotherapy protocol is supported by the supplied search results. Prescribing should nonetheless incorporate overdose risk and medication access. [23]
- Consider toxicity in overdose, specifically including opioid-containing analgesics and tricyclic antidepressants. [23]
- Review recreational drug and alcohol use when prescribing to a person who has previously self-harmed or may self-harm. [23]
- Medication decisions should be integrated with treatment of the underlying psychiatric, substance-use, medical, and psychosocial drivers; agent selection and dosing require current condition-specific guidance not supplied here. [5]

*Disposition-focused documentation elements. [5][9][20][24]*

| Element | Document explicitly |
| --- | --- |
| Current suicidal state | Ideation, intent, plan, preparatory behavior, and whether suicidal thoughts are escalating, persistent, or resolving. [5][20] |
| Behavioral history | Prior attempts or self-harm; frequency; medical seriousness; and violent methods used. [24] |
| Means and mitigation | Access to lethal means, actions taken to reduce access, and who is responsible for those actions. [5] |
| Formulation | Static vulnerabilities, dynamic drivers, protective factors, and the reasoning connecting these findings to disposition. [5][9] |
| Plan and continuity | Safety actions, treatment referrals, involvement of supports where appropriate, and reassessment or follow-up plan. [5][9][23] |

## Reassess after transitions and treat the drivers of suicidal crisis

Risk changes with symptoms, circumstances, treatment exposure, and access to means.

Suicidal crisis often occurs in the context of mental illness or life crisis, and many patients are ambivalent about dying. Use that ambivalence to build a collaborative plan that identifies alternatives to suicidal action, supports, and actions to take as risk intensifies. [5]

Reassessment is particularly important after a new episode of self-harm, changes in suicidal ideation or intent, changes in social circumstances, medication changes, hospital discharge, or renewed access to lethal means. The need for repeated documentation over the clinical course is supported by risk-formulation literature, although the supplied sources do not establish fixed reassessment intervals. [9]

System-level pathways matter: primary care, emergency, inpatient, and behavioral health teams should define how positive screens are assessed, where urgent evaluation occurs, how safety concerns are communicated, and how patients are retained through transitions. Clear pathways and interteam communication can support crisis de-escalation and safeguarding. [22]
- At each reassessment, compare current ideation, intent, plan, means access, recent behavior, stressors, treatment engagement, and supports with the prior formulation. [5][9]
- Revise the safety and means-restriction plan whenever the anticipated method, environment, caregivers, or available medications change. [5][23]
- Avoid therapeutic nihilism: suicidal thoughts are not synonymous with inevitable suicide, and effective support can help patients recover from crisis. [5]

*Situations warranting renewed clinical formulation rather than reliance on a prior assessment. [5][9][22]*

| Trigger | Why reassessment matters | Priority action |
| --- | --- | --- |
| New or worsening suicidal ideation | Risk is dynamic and cannot be accurately inferred from a prior single-time-point assessment. [5][9] | Reassess intent, plan, means access, precipitants, supports, and disposition. [5][20] |
| Self-harm or suicide attempt | Frequency, medical seriousness, and method are clinically relevant history elements. [24] | Provide concurrent physical and mental health assessment and revise the management pathway. [22][24] |
| Care transition or discharge | Clinical risk management requires repeated documentation and continuity through the clinical course. [9] | Communicate formulation, safety actions, and follow-up responsibilities across teams. [9][22] |
| Medication or means-access change | Medication toxicity and access to lethal means can alter the practical consequences of suicidal intent. [5][23] | Review access, overdose toxicity, and the means-safety plan. [5][23] |

## Common questions

### Should a suicide risk score determine emergency department discharge?

No. Risk tools and global low-medium-high labels should not be used to predict future suicide or recurrent self-harm, decide who receives treatment, or determine discharge. Use structured findings within an individualized formulation and disposition plan. [23]

### What should be assessed after a positive suicide screen?

Assess suicidal-thought frequency, plan, intent, past suicidal behavior or self-harm, access to lethal means, acute drivers, supports, and ability to participate in a safety plan. [5][20][24]

### How should clinicians address medication safety in patients at risk of self-harm?

Consider overdose toxicity and medication access when prescribing, with particular attention to opioid-containing analgesics and tricyclic antidepressants; review recreational drug and alcohol use. [23]

### Can suicide be predicted accurately for an individual patient?

No. Available sources state that suicide cannot be predicted accurately in an individual at a single point in time. Prediction-model thresholds are context dependent and should not replace clinical assessment and management. [1][5]
