Suicide precautions for psychiatric inpatients: a review. 
This paper reviews the literature on the assessment and management of suicide risk of psychiatric inpatients.  Even though a large number of scales have been developed to assist the prediction of suicide for patients admitted for suicide ideas and attempts, none of them were designed to predict suicide in the short term.  However the Modified Suicide Intent Scale and the Hopelessness Scale appear to have the potential to predict immediate suicide risk.  Risk factors associated with specific psychiatric conditions were all derived retrospectively and their predictive validities have not been established by prospective studies.  Important issues relating to the management of suicidal inpatients, such as staff-patient relationships, use of constant observation and medical-legal aspects are reviewed.
