Researchers led by Leah Richmond-Rakerd analysed population-wide administrative data from nearly 5 million people in Norway and New Zealand. Mental health conditions were identified in primary care and inpatient hospital records, and injuries were found in primary care, hospital records and insurance claims. Participants were followed for 14 to 30 years.
The study found higher risks of later self-harm injuries and injuries from assault, and a clear increase in unintentional injuries such as falls and traffic accidents. Links were seen across many mental health conditions and many injury types, with especially strong associations for brain and head injuries. These risks could not be explained by previous injuries or socioeconomic background.
The authors call for better integration of injury prevention into mental health care, continued assessment of self-harm risk and use of evidence-based strategies to reduce victimisation.
