A joint study by the Health Research Board (HRB) and the Health Service Executive reports that from 2019 to 2021, there were 567 deaths among people with dual diagnosis (the co-occurrence of substance use disorder and mental health disorders). The majority of deaths (68%) were among men. The average age was 42 years.
The study, which was recently published in Irish Journal of Psychological Medicine, is based on data from HRB’s National Drug-Related Deaths Index.
Dr Suzi Lyons, Head of Unit at HRB’s National Health Information Systems, said:
“The area of dual diagnosis and drug-related deaths is complicated and multi-layered, with limited existing Irish data. This study will increase understanding of these complexities. It will also provide high-quality data and evidence to policy makers and service planners to help reduce harm and improve outcomes for people with dual diagnosis in Ireland.”
Types of substance use and mental health conditions
The most common drugs used were cocaine (48%), heroin (37%) and cannabis (36%).
The most common mental health conditions were depressive disorders (53%), anxiety disorders (37%) and specific personality disorders (7%).
Causes of death
The most frequent verdicts recorded were misadventure (47%). Some 27% died by suicide.
Almost equal proportions of deaths were poisonings (49%) and non-poisonings (51%). Most poisoning deaths involved an opioid-type drug and/or use of more than one drug (84%).
