7) National Self-Harm Registry Ireland (NSHRI)

A national system monitoring hospital presenting self-harm in the Republic of Ireland (ED visits), operated by the National Suicide Research Foundation, established in 2000 and supported by the HSE National Office for Suicide Prevention.

Country

Ireland. It covers all acute public and pediatric hospital emergency departments nationwide and has achieved full national coverage since 2006.

Type of Study

This is an ongoing registry/surveillance system that provides population-based monitoring of self-harm presentations. It is not a cohort in the prospective sense, but rather a continuous register of Emergency Department (ED) events; however, researchers can conduct cohort analyses (e.g. by linking registry cases to subsequent outcomes).

Data Collection

Trained Data Registration Officers visit each of the 32 hospitals weekly to extract and pseudonymise data from Emergency Department (ED) records. The data are then transferred electronically to the NSRF offices on a weekly basis. The system uses a standardised minimum dataset, including ICD-10 coding for methods, as well as information on age, sex, residence, and other variables.

Sample Size

Approximately 12,500 selfharm presentations per year.

Sample Size Characteristics

Sample characteristics include sex, age, geographic region, area of residence, and medical card status. In research publications, data are typically stratified by age groups (e.g. children aged 8–12, adolescents 13–17, young adults 18–25, and adults 26+).

Measurement of Mental Health

The registry captures whether a mental health (psychosocial) assessment was conducted as part of care following presentation, including its timing (in-hours vs. out-of-hours). However, it does not include direct measures of wellbeing, quality of life, or social indicators. Instead, it records the occurrence of assessments, clinical methods used, and recommended subsequent care pathways.

Data collected include:

  • Type of self-harm (coded in the NSHRI database using WHO ICD-10 classifications for intentional self-injury).
  • Mode of arrival at the hospital.
  • Date and time of arrival.
  • Type of treatment received.

Cohort Profile Available

No. Data dictionary is available.
