The mental health triage scale can be used at the initial assessment of the patient presenting to the ED.

This was developed for use with the NICE guidelines on self-harm [8].

It can be helpful in assessing risk of further self-harm or risk to others and highlights those patients requiring a higher level of supervision prior to full assessment [10].

Various suicide and self-harm risk assessment tools are available including the:

  • Pierce suicide risk assessment tool
  • Edinburgh risk of repetition tool
  • Beck suicide intent tool [11]

These have all been demonstrated to have a low accuracy for prediction of further deliberate self-harm (DSH) but their use can encourage prompt referral to psychiatric services for assessment.
