The Catalonia Suicide Risk Code Epidemiology Study: an Epidemiological Study of Suicide Attempts in Catalonia, Spain

• Conditions: Suicide; Suicide and Self-harm; Suicide, Attempted
• Interventions: Other: sociodemographic variables, somatic conditions, mental disorders, treatment and drug use

• Registration Number: NCT04235127
• Lead Sponsor: Hospital del Mar Research Institute (IMIM)

Brief Summary

Suicide attempts (SA) constitute a major public health issue worldwide. Research suggests that 2.7% of adult people ever attempt suicide; among children and adolescents this is estimated to be 6.0%. SA are related to subsequent suicide which represents an annual loss of 34.6 million years of life worldwide. Suicide attempts are also related to persistent physical and mental health issues, psychiatric hospitalizations, impaired academic performance, unemployment, partner abuse victimization and perpetration, having children removed by social services, loneliness, relationship difficulties, impaired social functioning and low life satisfaction. Despite this considerable societal impact, there is a lack of epidemiological research focussing on providing suicide attempt surveillance in the population, to inform public health action aimed at reducing risk for suicide attempts in the population, and to provide data-driven support for suicide risk assessment across healthcare settings. To address this shortcoming, the investigators designed the Catalonia Suicide Risk Code Epidemiology study. Using centralized Electronic Healthcare Record data from the entire public healthcare system of Catalonia, Spain, the CSRC-Epi study aims to estimate reliable suicide incidence rates, identify suicide attempt risk factors, and develop validated suicide attempt risk prediction tools.

Arm && Interventions

Group	Intervention	Description
Catalan population	sociodemographic variables, somatic conditions, mental disorders, treatment and drug use	The target population consists of the dynamic cohort of all Catalan residents during the 6-year period 2014-2019. Annual total population of Catalonia is between 7.5-7.6 million, with annual rates for immigration, emigration, birth and death being \~2.5%, \~1.9%, \~0.9%, and \~0.8%, respectively. Based on these figures, we expect a maximum of \~9.1 million individuals with Catalan residency status on at least one point in time over the 2014-2019 period. However, we expect SA in Catalonia to be extremely rare before the age of 10, in line with findings that self-injurious behaviour generally occurs as from the adolescent period. We will therefore exclude cases and controls that have not reached age 10 by the end of the 2014-2019 period (i.e., \~10.9%), lowering the total expected target population to \~8.1 million.

Primary Outcome Measures

Name	Time	Method
Number of catalan residents with suicide attempt (incidence)	2014-2019	Suicide attempt is a nonfatal, self-directed, potentially injurious behaviour with a non-zero degree of intent to die as a result of the behaviour, even if the behaviour does not result in injury

Secondary Outcome Measures

Name	Time	Method
Number of Catalan residents committing suicide (incidence)	2014-2019	Suicide is a fatal, self-directed, injurious behaviour with a non-zero degree of intent to die as a result of the behaviour
