    • a UK study carried out among psychiatric patients reported that a quarter of suicides occurred within three months of discharge out of which almost half of patients die within the first month (often before the preliminary follow up)
    • patients who were hospitalised for attempted suicide had the highest risk after discharge
• childhood history of trauma, sexual abuse/rape
• environmental/social
  • availability of means e.g., access to guns, medications
