BACKGROUND People who self-harm have an increased risk of premature death. The aim of this study was to investigate cause-specific premature death in individuals who self-harm, including associations with socioeconomic deprivation. METHODS We undertook a cohort study of patients of all ages presenting to emergency departments in Oxford, Manchester, and(More)
BACKGROUND Self-harm (intentional self-poisoning and self-injury) in children and adolescents is often repeated and is associated with increased risk of future suicide. We have investigated factors associated with these outcomes. METHOD We used data collected in the Multicentre Study of Self-harm in England on all self-harm hospital presentations by(More)
BACKGROUND Self-poisoning is a common method of suicide and often involves ingestion of antidepressants. Information on the relative toxicity of antidepressants is therefore extremely important. AIMS To assess the relative toxicity of specific tricyclic antidepressants (TCAs), a serotonin and noradrenaline reuptake inhibitor (SNRI), a noradrenergic and(More)
BACKGROUND Seclusion continues to be widely used in the management of disturbed behaviour in hospitalized patients. While early research on the topic highlighted significant differences in staff and patient perceptions, there are few recent data to indicate if these differences still exist. AIM This paper reports a study exploring the perceptions of both(More)
Self-harm is a major healthcare problem in the United Kingdom, but monitoring of hospital presentations has largely been done separately in single centres. Multicentre monitoring of self-harm has been established as a result of the National Suicide Prevention Strategy for England. Data on self-harm presentations to general hospitals in Oxford (one(More)
BACKGROUND Self-harm is a common reason for Emergency Department (ED) attendance. We aimed to develop a clinical tool to help identify patients at higher risk of repeat self-harm, or suicide, within 6 months of an ED self-harm presentation. METHOD The tool, the ReACT Self-Harm Rule, was derived using multicentre data from a prospective cohort study.(More)
BACKGROUND Self-harm is a common reason for presentation to the Emergency Department. An important question is whether psychosocial assessment reduces risk of repeated self-harm. Repetition has been investigated with survival analysis using various models, though many are not appropriate for recurrent events. METHODS Survival analysis was used to(More)
Repetition of deliberate self-harm (DSH) is common. Some patients repeat multiple times. We have investigated the characteristics of repeaters, and mortality in three groups of DSH patients by repetition status. Data collected by the Oxford Monitoring System for Attempted Suicide were used to examine the pattern of repetition of DSH patients presenting to a(More)
BACKGROUND Self-harm is a key risk factor for suicide and it is important to have contemporary information on the extent of risk. METHODS Mortality follow-up to 2012 of 40,346 self-harm patients identified in the three centres of the Multicentre Study of Self-harm in England between 2000 and 2010. RESULTS Nineteen per cent of deaths during the study(More)
We examined epidemiology and characteristics of self-harm in adolescents and impact of national guidance on management. Data were collected in six hospitals in three centres between 2000 and 2007 in the Multicentre Study of Self-harm in England. Of 5,205 individuals (7,150 episodes of self-harm), three-quarters were female. The female:male ratio in 10–14(More)
