Abstract

Background: There is little information about characteristics and long-term outcomes of individuals who self-harm during a suicide cluster. Aims: To compare characteristics of individuals who self-harmed during a suicide cluster in South Wales (~10 deaths between Dec 2007 and Mar 2008) with others w...

Method: Using records from the hospital serving the catchment area of the suicide cluster, enhanced by national routinely collected linked data, we created two groups: individuals who self-harmed a) during the suicide cluster, and b) one year before. We compared individuals’ characteristics and performed logistic regression to compute odds ratios of 10-year self-harm and mortality outcomes. Results: Individuals who self-harmed during the cluster were less likely to be hospitalized or have a mental health history than those who self-harmed prior to the cluster. No significant group differences were found for 10-year self-harm outcomes, but all-cause mortality was higher for males. Limitations: Sample size was small, and data were lacking on psychological and social proximity to individuals who died during the suicide cluster. Conclusion: Our findings highlight the importance of long-term healthcare follow-up of those who self-harm during a suicide cluster, particularly males.</abstract><type>Journal Article</type><journal>Crisis</journal><volume>0</volume><journalNumber/><paginationStart/><paginationEnd/><publisher>Hogrefe Publishing Group</publisher><placeOfPublication/><isbnPrint/><isbnElectronic/><issnPrint>0227-5910</issnPrint><issnElectronic>2151-2396</issnElectronic><keywords>Self-harm, suicide, suicide cluster, data linkage, mortality</keywords><publishedDay>31</publishedDay><publishedMonth>10</publishedMonth><publishedYear>2023</publishedYear><publishedDate>2023-10-31</publishedDate><doi>10.1027/0227-5910/a000930</doi><url/><notes/><college>COLLEGE NANME</college><department>Health Data Science</department><CollegeCode>COLLEGE CODE</CollegeCode><DepartmentCode>HDAT</DepartmentCode><institution>Swansea University</institution><apcterm/><funders>This work was funded by Health and Care Research Wales (Grant Number SCS-12-14) and by the Welsh Government through Health and Care Research Wales (grant awarded to The National Centre for Mental Health, No. CA04).
