Open access. Suicide is a global problem and suicidal behavior is common in acute psychiatric wards. Inpatient suicides regularly occur with 10.4/100,000 such deaths recorded in the UK in 2016. Inpatient suicides are potentially the most avoidable of all suicides as inpatients have 24-h staff contact. Current inpatient treatment prioritizes maintenance of physical safety by observation, medication and general supportive measures, however efficacious and effective specific treatments are lacking. Psychological treatments have a growing evidence base for suicide prevention yet provision of inpatient therapy is uncommon. The present qualitative study aimed to understand the patient acceptability issues by investigating suicidal inpatients views and expectations of a novel suicide-focussed cognitive behavioural psychological therapy which was nested alongside a pilot clinical trial of the intervention.
