Research from Australia and New Zealand's Intensive Care Society's Paediatric Study Group has found a marked increase in ICU admissions for deliberate self-harm

The authors says it coincides with Covid-19 lockdowns and social restrictions over the past two years.

They say at the onset of the pandemic, monthly rates of deliberate self harm ICU admissions per million young people ... increased from 7.2 in March 2020 to more than 11 by August 2020.

Monash Children's Hospital pediatric ICU director Felix Oberender says the numbers are concerning.
