  • Other: mechanisms that if listed may affect patient anonymity.

  • *The percentages reported in this section are the proportion of all DSH-I patient encounters for each mechanism that were classified as ‘severe’; for example, in the control period, two out of six (33.3%) hangings were ‘severe’.

  • DSH-I, deliberate self-harm incident.
