Suicide in mental health service users
Suicides by people in contact with mental health services are arguably the most preventable. There is scope for reducing some of these tragic events through improved systems of care. As part of the national ambition to reduce suicide by 10% by 2020/21, the Five Year Forward View for Mental Health has recommended that deaths by suicide across NHS-funded mental health settings are learned from to prevent repeat events.
The National Confidential Inquiry into Suicide and Safety in Mental Health (NCISH) suicide rates differ from ONS rates because they base their figures on date of death rather than the date when the death was registered. In addition, the figures include people aged 10-14 and are not age-standardised, i.e. they are not adjusted to reflect differences in the age of the population.
Completeness of the data is lower in the more recent years reported, reflecting the time required to receive and process the data. For example, in 2014, 2015 and 2016 completeness for England is 89%, 85% and 73% respectively. For these years, therefore, they projected the number of total patient cases based on the expected final return of NCISH questionnaires for the previous eight years (2006-2013).
