Background

Optimizing psychiatric assessments could help to

standardize the use of structured instruments in clinical practice. In

recent years, several research groups have applied Computerized

Adaptive Tests (CATs) to simplify assessments in depression, anxi-

ety and also suicidal behaviors. We aimed to construct a shortened

test to classify suicide attempters using a decision tree method-

ology that allows the integration of relevant clinical information,

namely the history of past suicide attempts, in the construction of

the test.

Methods

The sample was composed of 902 adult participants in

three subsamples: first-time suicide attempters, psychiatric inpa-

tients that never attempted suicide and healthy controls. The

performance of a decision tree built using the items of a previously

developed scale for suicidal risk was examined. The history of past

suicide attempts was used to separate patients in the decision tree.

The data was randomly divided in a training set and a test set. The

test set, that contained 25% of the data, was used to determine the

accuracy of the decision tree. Twenty-five cross-validations of this

set up were conducted.

Results

The first four items of the decision tree classified correctly

81.4% of the patients.

Conclusion

As a result of a methodology based on decision trees

that, contrary to CATs, can incorporate relevant information in

building the test we were able to create a shortened test capa-

ble of separating suicidal and non-suicidal patients. Using all the

information that is available improves the precision and utility of

instruments adapted for psychiatric assessments.

Introduction

Suicide causes 1.4% of deaths worldwide. Twenty

times more frequent, suicide attempts entail an important source

of disability and of psychosocial and medical resources use.

Objective

To describe main socio-demographical and psychiatric

risk factors of suicide attempters treated in a general hospital’s

emergency room basis.

Aims

To identify individual features potentially useful to improve

both emergency treatments and resource investment.

Methods

A descriptive study including data from 2894 patients

treated in a general hospital’s emergency room after a suicidal

attempt between years 2006 and 2014.

Results

Sixty-nine percent of the population treated after an

attempted suicide were women. Mean age was 38 years old. Sixty-

six percent had familiar support; 48.5% had previously attempted

a suicide (13% did not answer this point); 72.6% showed a personal

history of psychiatric illness. Drug use was present in 38.3% of the

patients (20.3% did not answer this question); 23.5% were admit-

ted to an inpatient psychiatric unit. Medium cost of a psychiatric

hospitalization was found to be 4900 euros.

Conclusion

This study results agree with previously reported

data. Further observational studies are needed in order to bear out

these findings, rule out potential confounders and thus infer and

quantify causality related to each risk factor.

Introduction

Suicide behavior constitutes a public health prob-

lem worldwide. It deserves epidemiological investigation regard-

ing “best clinical practices”, and it is fundamental since the patient’s

first observation at psychiatric emergencies services. These are the

ideal practices to start suicide prevention, and prevent further sui-

cidal behavior. The improvement of healthcare quality includes the

adoption of clinical guidelines, which support medical care since

the emergencies services. The lack of specific instruments to eval-

uate suicidal risk urges the scientific community to create them.

Aims

The authors aim to discuss the advantages and limitations

of the application of these kinds of instruments, and the creation of

models based in scientific evidence available.

Discussion

From multiple available studies, the Modified Sad-

Persons Scale (MSPS) seems to be one of the most scientifically

used in literature, as well as in epidemiological studies of suicide

attempts and their repetition, either by nonfatal or fatal attempts.

However, even this scale has been questioned by experts, and the

lack of specific and sensible tests towards suicide behavior and

risk of suicide attempts raises the importance of the need of fur-

ther investigation towards this area. This evidence would then help

the clinician in his work at emergencies wards and provide better

healthcare towards preventing new suicide attempts.
