Mental health nurses’ experiences of risk assessment of patient self harm in a Psychiatric Intensive Care Unit. Abstract The ongoing high rates of deliberate self harm in Ireland reflect the high level of psychological and psychiatric morbidity in the population. Mental health nurses work with people who self harm in many varied settings. Mental health nurses conduct risk assessments with patients on a daily basis. Although studies have explored the work and experiences of these nurses, there is a dearth of research which has explored the experiences of mental health nurses conducting risk assessments with patients who self harm in Psychiatric Intensive Care Units (PICU). This study endeavoured to gain an understanding of mental health nurses` experiences of risk assessment of patients who self harm psychiatric intensive care unit. A qualitative descriptive approach was undertaken. The sample consisted of seven registered nurses from a PICU in one Health Service Executive (HSE). Data was collected using semi – structured interviews and analysed using content analysis. Analysis of the data identified mental health nurse’s varied awareness and nursing practices when conducting risk assessments with patients who self harm. Four themes emerged: nurses’ understanding of self harm behaviour, nurses’ understanding of risk assessment, risk assessment nursing practices and the role of education for nurses conducting risk assessments with people who engage in self harm behaviour. It is recommended that there is a need to examine policies and develop guidelines for working with people who self harm. This research illustrates that there is a need to develop risk assessment guidelines appropriate to local service user needs. The effectiveness of risk assessment approaches for working with people who self harm needs to be evaluated. In service training is needed to inform nurses of evidence based structured risk assessment practices for working with people who self harm.
