The association between alcohol and self-harm
The impact of alcohol on seasonal patterns of self-harm
among men and women
The impact of alcohol on self-harm among adolescents
Alcohol, associated mental health problems and suicide
risk
Evidence based actions
3. Irish National Registry of Deliberate Self-Harm
(NRDSH)
•
Objectives
To establish the incidence of
hospital treated deliberate selfharm
•
To describe the pattern of
presentations and the nature of the
self-harm behaviour involved
•
To monitor trends over time and by
area
•
To estimate the risk of repeated
self-harm presenting to hospital
In 2012, there were 12,010 presentations made by 9,483 individuals

7. Association between peaks of self-harm and
public holidays
Average number of self-harm presentation to hospital
per day: n=33
Six dates in the year on which 50 or more self-harm
presentations were made, 5 of which were public
holidays or the day after:
- January 1st
- October 1st
- March 17th and 18th
- June 5th
8. The impact of alcohol
Alcohol abuse is one of the factors contributing to the high rates of self-harm
among young people and adults in Ireland
Direct effects:
Impairs problem-solving ability
Increases impulsivity and lack of control
Increases feelings of depression, stress, anger or anxiety
Long term and indirect effects:
Isolation (loss of work, relationships, etc.)
Neurobiological deficits

McMahon et al, 2010;Khalily & Hallahan, 2012

11. Main outcomes
Alcohol contributes to increasing rates of self-harm and it
causes increases of self-harm at specific times in the year,
such as a peak of self-harm in July and August.
This peak would not exist if alcohol would not be involved.

17. Main outcomes
Alcohol is associated with increasing self-harm among both men
and women
Alcohol contributes to increases of self-harm at specific times in
the year and week
Alcohol is associated with increasing trends in highly lethal
methods of self-harm, in particular among men
18. International comparative study on
self-harm and associated factors
Child and Adolescent Self Harm in Europe (CASE)
The CASE study is a multi-centre study in 6 countries across Europe
and 1 non-European centre (Australia).
Objectives:
The prevalence of self harm-among 15-17 year olds
and the relationship with risk factors (e.g. depression, anxiety,
alcohol, drug use/misuse etc.) and protective factors (e.g.
coping, help seeking) across different countries
Young people’s opinions on the prevention of mental health
difficulties

21. Main outcomes
Heavy alcohol consumption increases risk of selfharm independent of other factors
Less so in Ireland than in other countries
Reducing Irish adolescents’ heavy drinking should
reduce their rate of deliberate self harm (<17%)
22. Suicide Support and Information System (SSIS):
Obtaining a complete picture of suicide cases and open
verdicts by accessing multiple sources
Coroners' verdict records
& Post mortem reports
(Response Rate: 100%)

(Response Rate:

(Response Rate:

• Period and area
covered:
Sept. 2008-June 2012,
City and County Cork
• Number of consecutive
cases: 275 suicide cases
+ 32 open verdicts
meeting screening
criteria; Total N=307
23. Second SSIS Report: Key findings from a study
looking at 307 suicide deaths in Cork
•
•
•
Overrepresentation of men (80.1%); Men
significantly younger than women
Nearly two thirds had a history of self-harm
(65.2%); 69.1% were diagnosed with
depression, and alcohol/and or drug abuse was
present among 60.7%
Among those with alcohol and/or drug abuse,
48.6% had abused alcohol, 27.6% had abused
both alcohol and drugs, and 21% had abused
drugs
Among 20.8% an increase in alcohol and/or drug
abuse was observed in the year prior to death
24. Characteristics of the suicide act
Method of suicide: hanging (63.8%), drowning (12.4%),
intentional overdose of medication/drugs (9.8%), other methods
(14%)
At the time of death, the majority (79%) had alcohol and/or drugs
in their toxicology. 24.4% had alcohol + drugs, 34.6% had drugs
only, and 20% had alcohol only
Use of alcohol and/or drugs increases the risk of a fatal outcome
(Kaplan et al, 2013)

27. Evidence based actions
National strategies to reduce access to alcohol should be intensified.
National strategies to increase awareness of the risks involved in the
use and misuse of alcohol should be intensified, starting at preadolescent age.
Active consultation and collaboration between the mental
health- and addiction services needs to be arranged for patients
who present with dual diagnosis (psychiatric disorder and
and alcohol/drug abuse).
28. Evidence based actions
Health care professionals working with people who engage in selfharm should receive training in the assessment and management of
self-harm and co-morbid alcohol and drug misuse/abuse.
Health care professionals prescribing medication to people at risk of
self-harm or suicide should carefully monitor compliance with
appropriate use of medication.
29. Evidence based actions
Breaking the commercially reinforced links between alcohol and
sport.
Recruit the major national sporting organisations as partners in
the development of a national positive mental health promotion
campaign.
