Self Harm Emergency Department Attendances in Wales in the 15-17 and 18-24 age groups

  • Rates have increased by 1.5 times for females aged 15-17 years between 2011 and 2014 (from 404.8 per 100,000 in 2011 to 600.2 per 100,000 in 2014, Figure 1). There is a slight increasing trend in the rates for 15-17 year old males (from 186.0 per 100,000 to 229.5 per 100,000) and 18-24 year old females (from 302.0 per 100,000 to 344.4 per 100,000, Figure 2).
  • The rate of self harm attendances in 18-24 year olds in the most deprived areas of Wales is 2.5 times the rate of young people living in the least deprived areas (466.8 per 100,000 in the most deprived, 186.4 in the least deprived, Figure 3). The rate is 1.6 times larger in 15-17 age group (518.2 per 100,000 in the most deprived, 324.2 per 100,000 in the least deprived, Figure 3)
  • Abertawe Bro Morgannwg University Health Board have the highest rate of attendances in 15-17 year olds (676.7 per 100,000, Figure 4) and Aneurin Bevan University Health Board have the highest rate in 18-24 year olds (491.9 per 100,000). Cardiff and Vale University Health Board have very low rates in both age groups. Please note that there is considerable variation in how injuries are recorded in different hospitals and how these are then mapped to the mandated Emergency Department Data Set (EDDS). Therefore differences between Health boards should be interpreted with caution. The quality of data and the number of injuries recorded is expected to improve following the introduction of a new all-Wales ED computer system this year.

Figure 3. Intentional self harm attendance rates for 15-24 year olds by Welsh Index for Multiple Deprivation 2011 fifths (2013-2015 average). WIMD is the official measure of multiple deprivation at the small area level; quintile 1 representing the most deprived 20% of areas and quintile 5 representing the least deprived 20% (e.g. most affluent) in Wales.
