Question to the Department of Health and Social Care:

To ask the Secretary of State for Health and Social Care, what information his Department holds on the number of homicide incidents in each of the last 12 months which involved a suspect who had been a patient of an NHS mental health trust within the preceding six months.

NHS England commissions the National Confidential Inquiry into Suicides and Homicides (NCISH) which has two functions in relation to homicides. First, it reports a count of homicides by people in the care of mental health services. Second, it does research into suicides and homicides, with the aim of helping to identify opportunities for improvements to clinical care in order to improve safety.

The ‘count’ of patient homicides by people under the care of mental health services, is not real-time, and there is a delay between the incident occurring and the incident being included in this national data. This is because an incident can only be confirmed as a mental health homicide when a judicial process has determined whether a homicide has been committed and by whom, as well as the nature of the crime.

In line with the national Patient Safety Incident Response Framework, in addition to local provider led safety reviews, any reported homicides/suspected homicides involving mental health patients are shared for review by regional NHS England teams, to establish whether an independent investigation is also required. Those requiring independent investigation are commissioned by regional teams.
