How to Triage Suicide Attempt Risk in Distressed Health Care Workers
How should clinicians stratify short-term suicide attempt risk in emotionally distressed health care professionals using baseline suicidal ideation and sleep disturbance?
Health care professionals seeking support for emotional distress may have substantial near-term suicide risk, especially during sustained occupational crises. In Risk Factors for Suicide Attempts and Psychiatric Hospitalization Among Brazilian Health Care Professionals, baseline suicidal ideation and sleep disturbance separated a very low-risk group from a subgroup with more than 50% 24-week attempt probability.
-
Screen suicidal ideation with PHQ-9 item 9
Ask PHQ-9 item 9 about thoughts of being better off dead or self-harm over the last 2 weeks and record the response as not at all, several days, more than half the days, or nearly every day. Treat the result as an ordinal severity signal because the study found a dose-response relationship for later suicide attempts, with higher risk at each increasing response category.
-
Assess sleep disturbance severity at baseline
Measure sleep problems using the PROMIS sleep disturbances short form, which evaluates sleep quality, insomnia, agitation, worry, and satisfaction over the past 7 days. Classify sleep severity because sleep disturbance remained independently associated with suicide attempts after adjustment, including mild, moderate, and severe levels.
-
Identify daily suicidal ideation as the strongest single warning sign
Flag nearly every day suicidal ideation as the highest-risk ideation category for near-term suicide attempts. In the multivariable model, nearly every day ideation had the strongest association with attempts, while more than half the days and several days also remained associated but at lower magnitude.
-
Escalate concern when severe sleep problems and daily ideation coexist
Treat the combination of nearly every day suicidal ideation and severe sleep disturbance as the highest-risk baseline profile. The 24-week suicide attempt probability was 57.1% when both were present, compared with 42.3% for nearly every day ideation alone, 12.3% for severe sleep alone, and 1.2% for neither; additive interaction analysis suggested substantial synergy.
-
Use the clinical risk score to sort patients into strata
Apply the study's clinical risk score by assigning 3 points for ideation frequency, 2 points for sleep severity, and 1 point for male sex. Stratify total scores as low risk at 0 to 2 points, moderate at 3 to 5, high at 6 to 8, and very high at 9 or more, corresponding to observed attempt rates of 0.8%, 4.2%, 18.7%, and 45.3%, respectively.
-
Avoid using PHQ-9 item 9 alone to rule in high risk
Do not make high-risk decisions based on PHQ-9 item 9 alone. In this sample, PHQ-9 item 9 had sensitivity of 71.7%, specificity of 77.8%, positive predictive value of 12.9%, and negative predictive value of 98.3%, so it functioned better as a rule-out than a standalone rule-in tool.
-
Prioritize urgent integrated prevention for the highest-risk subgroup
When daily suicidal ideation and severe sleep problems are both present, prioritize urgent preventive intervention rather than treating these domains as separate background symptoms. The authors specifically concluded that this subgroup needs urgent preventive intervention measures and that integrated interventions addressing both domains simultaneously may be more effective than targeting either alone.
Clinical Considerations
- The clinical risk score showed good discrimination in this sample but requires prospective validation before implementation.
- PHQ-9 item 9 missed a meaningful minority of later attempters, with 28.3% of attempts occurring among participants who reported no baseline ideation.
- The association between male sex and suicide attempts had borderline significance and contradicted usual epidemiologic patterns, so it warrants cautious interpretation.
- Generalizability is limited because the cohort consisted of Brazilian health care professionals seeking psychological support during the COVID-19 pandemic.
Bottom Line
For distressed health care professionals, the most clinically useful baseline triage pattern for suicide attempts is suicidal ideation plus sleep disturbance, with daily ideation and severe sleep problems marking an urgent high-risk group.
