Psychiatry - basic suicide risk assessment and its limitations

Overview

Suicide risk assessment involves structured enquiry into suicidal ideation, intent, plan, and access to means, alongside identification of relevant risk and protective factors - a direct, non-judgemental approach to asking about suicidal thoughts does not increase risk (a persistent myth) and is essential to accurate assessment
A core clinical skill relevant across essentially all clinical practice, not only dedicated psychiatric settings, given that patients experiencing suicidal ideation frequently present first to general medical rather than psychiatric services

Risk is not static - it fluctuates over time and with circumstances, meaning a single risk assessment provides only a point-in-time estimate, and ongoing reassessment is needed for any patient with identified risk, particularly around clinically significant transitions (discharge, treatment changes, significant life stressors) where risk can change rapidly

Direct, specific questioning (ideation, intent, plan, means, timeline) rather than vague or indirect enquiry provides more clinically useful information - asking directly about suicidal thoughts does not increase the risk of a patient acting on them, a persistent but incorrect belief that can lead to under-assessment through avoidance of direct questioning
Risk factors (prior attempts, mental illness, substance use, social isolation, access to lethal means) and protective factors (social support, reasons for living, engagement with treatment) should both be systematically assessed together

Assessed risk level should directly inform the safety plan - ranging from outpatient follow-up with a structured safety plan for lower risk, to urgent psychiatric assessment or involuntary admission consideration for imminent, high-risk presentations
Means restriction counselling (reducing access to identified lethal means, e.g. firearms, stockpiled medication) is a specific, evidence-based intervention regardless of overall risk level

Direct questioning not increasing risk (a frequently tested myth-correction), means restriction as an evidence-based intervention, risk fluctuation requiring ongoing reassessment (particularly at care transitions), risk and protective factor systematic assessment
Directly asking a patient about suicidal thoughts does not increase their risk of acting on them - this is a well-established finding that corrects a persistent, incorrect clinical belief, and avoiding direct questioning out of misplaced concern about "planting the idea" actually undermines accurate risk assessment rather than protecting the patient
