Suicidal ideation — broadly defined as thoughts, considerations, or plans relating to suicide — is among the more frequently encountered clinical presentations across healthcare settings, yet a substantial proportion of the professionals who face it report feeling underprepared. A clinical update published in the BMJ brings together current evidence on how the condition is identified, who is most at risk, and which interventions carry the strongest research support.
A Near-Universal Clinical Reality
The scale at which healthcare professionals encounter patient suicide is striking. A systematic review drawing on 41 studies conducted across 15 countries, cited in the BMJ update, found that roughly 87% of general practitioners will experience the death of at least one patient by suicide over the course of their career. Among psychiatrists — whose patient populations carry elevated risk by definition — the figure stood at 73%. Across all health professional groups combined, the proportion was approximately 51%.
These numbers frame suicidal ideation not as a rare or specialist concern but as a near-universal feature of clinical practice, one that extends well beyond mental health services into primary care, emergency departments, and beyond.
Who Is at Greater Risk
The BMJ update identifies several characteristics associated with elevated likelihood of suicidal ideation. Psychiatric diagnoses feature prominently, as does age — with both younger and older adults appearing in higher-risk categories. Female sex, the presence of physical disabilities, and marginalised social status are also listed among the recognised risk factors.
The breadth of this list reflects the complexity of suicidal ideation as a clinical phenomenon. It does not map neatly onto a single demographic or diagnostic group, which in turn complicates decisions about when and how to screen for it.
Screening: Targeted Rather Than Universal
On the question of screening, the update is clear about where current guidance stands: no established clinical guidelines endorse universal screening for suicidal ideation across the general population. Instead, the recommended approach involves directing screening efforts toward populations already identified as being at elevated risk.
This targeted model reflects both the practical constraints of routine clinical encounters and the absence of robust evidence that universal screening produces better outcomes. It also places considerable weight on clinicians being able to identify which patients warrant closer attention — a task that, according to the update, many feel ill-equipped to perform.
A Training Gap With Real Consequences
Perhaps the most consequential finding highlighted in the BMJ update concerns the mismatch between clinical exposure and clinical preparedness. The majority of clinicians, the update reports, describe their training in the assessment and management of suicidal ideation as inadequate.
Data from a 2018 cross-sectional study of 208 European general practitioners, cited in the update, puts specific numbers to this gap. Only around 35% of those GPs reported feeling comfortable when assessing suicide risk in their patients. Slightly more than half — 53% — had received any prior training in suicide prevention, encompassing detection and evidence-based treatment approaches.
Taken together, these figures suggest that a meaningful proportion of the clinicians most likely to encounter suicidal patients in everyday practice have had limited formal preparation for doing so. General practice, as the first point of contact for many people in psychological distress, sits at a particularly important juncture.
Treatment: Where the Evidence Points
Among the interventions reviewed in the BMJ update, cognitive behavioural therapy (CBT) emerges with the strongest evidence base for addressing suicidal ideation directly. CBT, which focuses on identifying and restructuring patterns of thought and behaviour, has accumulated a more substantial body of supporting research than other therapeutic approaches in this area.
The update does not position CBT as the only relevant intervention, but the weight of evidence behind it distinguishes it from alternatives. This matters in a clinical landscape where treatment decisions are often made under uncertainty, with limited time and variable access to specialist services.
Context and Limitations
The BMJ clinical update is directed primarily at practising clinicians rather than the general public, and its recommendations are framed accordingly. It does not advocate for any single screening tool or treatment protocol as universally applicable, acknowledging instead that clinical judgement — informed by evidence — remains central to managing suicidal ideation in individual patients.
What the update does make plain is that the current state of clinician training is not keeping pace with the frequency of clinical need. With more than eight in ten GPs statistically likely to lose a patient to suicide at some point in their career, the gap between exposure and preparedness carries weight beyond the individual clinician.
