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.
