Objectives suicide and self-inflicted injuries are the leading
causes of injury-related deaths worldwide. The aim of this work
is to investigate sociodemographic characteristics as a risk factor
for suicide. The investigation covers the period from 1997 to 2011
on the territory of the capital of Serbia, the city of Belgrademethods.
The data was taken from the index books of suicides committed in
the city of Belgrade, held at the Institute of Informatics and Statis-
tics. Statistical analysis was done using the crude specific rate. The
variability of the rate was estimated by computing a confidence
interval.
Results The average suicide rate in the observed period is 9.88.
The suicide rate shows a regular decline until 2005, and from that
time on mild growth (the highest in 2000, the lowest in 2004). The
results of our study point out the following sociodemographic pro-
file as a risk factor for suicide: male with uncompleted elementary
school who lives in a suburban community, aged 66 and over; sui-
cides are usually realized in the area of residence during the day, in
late spring, and hanging is the most frequent method of suicide.
Conclusion Preventive public health measures should be imple-
mented focusing on typical socio-demographic profile. Prospective
studies should include more variables in order to identify more
risk factors for suicide and suicidal behavior. To achieve this, a seri-
ous national strategy for recording suicide and suicide prevention
would have to be developed.

Introduction Suicide is a leading cause of death worldwide and is
largely preventable. The social media site Twitter is used by individ-
uals to express suicidal intentions. It is not yet feasible to contact
each Twitter user to confirm risk. Instead, it may be possible to
validate risk by linguistic analysis. Psychological linguistic theory
suggests that language is a reliableway ofmeasuring people’s inter-
nal thoughts and emotions; however, the linguistics of suicidality
on Twitter is yet to be fully explored.
Objectives & aim The aim of this study is to characterise the lin-
guistic styles of suicide-related posts on Twitter for the purposes
of predicting suicide risk.
Methods The Linguistic Inquiry and Word Count (LIWC) pro-
gramwas used to compare the linguistic features of suicide-related
tweets previously coded for suicide risk by humans with a set of
matched controls. Logistic regression was then used for predictive
modelling.
Results The suicide-related tweets had significantly different lin-
guistic profiles to the control tweets. The “strongly concerning”
suicide tweets were found to have fewer words than all other
tweets and not surprisingly, references to ‘death’ were significantly
higher in this group. A number of other results were found. The
final model which distinguished “strongly concerning” suicide risk
from the controls was found to have 97.7% sensitivity and 99.8%
specificity.
Conclusions This study confirms that the linguistic features of
suicide-related Twitter posts are different from general Twitter
posts and that these linguistic profiles may be used to predict sui-
cide risk in Twitter users.

Introduction We previously reported on a series of sudden and
unexpected deaths in Donegal patients (EPA 2015). We are now
presenting some initial data on a Suicide Crisis intervention service
established in February 2015 as part of the response to the increas-
ing service user suicides in Co. Donegal, Ireland. The Donegal
Suicide Crisis Assessment Nurse (SCAN) is a nurse led service which
works closelywithGeneral Practitioners (GP’s), mainstreammental
health services, and non-statutory service providers.
Objectives/aims Our audit presents the activity of SCAN service
in Donegal over the February-August 2015 period.
Method We extracted the demographic data pertaining to the
referrals from the SCAN data-base using R software for statistical
analysis.
Results There were (n = 65) referrals during the five-month study
period (41.5% men and 51% women). There were ( n = 60) 90.9%
referrals for suicidal ideations, ( n = 6) 9.1% for engagement in
deliberate self-harm and (n = 9) 13.6% following suicidal attempts.
Alcohol misuse was a significant issue in (n = 16) 24.2% referrals.
Themean age was 36.0 years (SD = 16.0 years); 40.7 years (SD = 16.8
years) for males, and 32.7 years (SD = 14.8 years) for females. The
male-female age difference was significant (P = 0.0461). The major-
ity of patients (n = 24) were seen the following day. There were
(n = 16) who were seen the same day of referral. Only (n = 5) were
seen two days after their referral, with (n = 4) patients seen the third
day or more.
Conclusion The SCAN service in Donegal is growing month-by-
month. Males referred tend to be significantly older than females,
otherwise, no demographic difference was apparent.
