BackgroundSelf-harm and intentional injuries represent a significant public health concern. People who survive serious injury from self-harm can experience poor outcomes that negatively impact on their daily life. The aim of this study was to investigate a cohort of major trauma patients hospitalised for self-harm in Victoria, and to identify risk factors for longer term mortality, functional recovery and return to work.Method482 adult major trauma patients who were injured due to self-harm and survived to hospital discharge, and were captured by the population-based Victorian State Trauma Registry (VSTR), were included. For those with a date of injury from January 1, 2007 to December 31, 2013, demographics and injury event data, Glasgow Outcome Scale Extended (GOS-E) and return to work (RTW) outcomes at 6, 12 and 24 months post-injury were extracted from the registry. Post-discharge mortality was identified through the Victorian Registry of Births, Deaths and Marriages (BDM). Multivariable logistic regression was used to determine predictors of the GOS-E and RTW and survival analysis was used to identify predictors of mortality.ResultsA total of 37 (7.7%) deaths occurred post-discharge. There were no clear predictors of all-cause mortality. Overall, 36% of patients reported making a good recovery at 24 months. Older age (p=0.01), transport-related methods of self-harm (p=0.02), higher Injury Severity Score (p<0.001) and having a Charlson Comorbidity Index weighting of one or more (p=0.02) were predictive of poorer functional recovery. Of patients who were working or studying prior to injury, 54% reported returning to work by 24 months post-injury. Higher Injury Severity Score was an important predictor of not returning to work (p=0.002).ConclusionThe vast majority of major trauma patients who self-harmed and survived to hospital discharge were alive at two years post-injury, yet only half of this cohort returned to work and just over a third of patients experienced a good recovery.Copyright © 2016 Elsevier Ltd.
