Using big data to understand the predictors of repeated self-harm in people with mental health and drug and alcohol comorbidity

Past project

Chronic use of alcohol and other drugs is one of the greatest risk factors for repeated self-harm and suicide. Very few studies have specifically focussed on preventing repeated presentation to acute health services and admission for self-harm specifically for people with drug and alcohol comorbidity. To best design such interventions, a better understanding of the specific predictors of repeated self-harm in this population is necessary but under-researched. We used big data to directly address this gap.
