The overall aim of the research is contribute to a reduction in suicides within mental health services. This study will explore the learning process for mental health services following patient suicides in Northern Ireland (NI). It will focus on how the recommendations contained in Serious Adverse Incident reports, which are completed following all patient suicides, are translated into practice. The study will examine all SAI reports completed from January 2015 to December 2016. Focus groups with mental health professionals throughout NI will then be used to increase understanding of the enablers and barriers to effective implementation of these recommendations within mental health services.
