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.
Core approach
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.

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.

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. ScienceDirectScienceDirectSuicide risk assessment and formulation: An update
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.

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. nice org uknice org ukRecommendations | Self-harm: assessment, management and preventing recurrence | Guidance | NICE
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.

Detection
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. ScienceDirectScienceDirectClinical Pathway for Suicide Risk Screening in Adult Primary Care Settings: Special Recommendations
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. ScienceDirectScienceDirectClinical Pathway for Suicide Risk Screening in Adult Primary Care Settings: Special Recommendations In the ASQ assessment framework, follow-up evaluation includes suicidal-thought frequency, presence of a suicide plan, and past suicidal behavior. pediatrics aappublicationspediatrics aappublicationsSuicide and Suicide Risk in Adolescents | Pediatrics
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. cks nice org ukcks nice org ukScenario: Acute management of a person at risk of self-harm 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.

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.

Immediate safety
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.

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.

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. nice org uknice org ukRecommendations | Self-harm: assessment, management and preventing recurrence | Guidance | NICE

Continuity
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. BMJBMJSuicide risk mitigation - Symptoms, diagnosis and treatment | BMJ Best Practice US
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. ScienceDirectScienceDirectSuicide risk assessment and formulation: An update
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.

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. nice org uknice org ukRecommendations | Self-harm: assessment, management and preventing recurrence | Guidance | NICE
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.

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. nice org uknice org ukRecommendations | Self-harm: assessment, management and preventing recurrence | Guidance | NICE
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.
