Post-traumatic stress disorder and major depression among frontline healthcare staff working during the COVID-19 pandemic.

We found high diagnostic rates of PTSD (44%) and major depression (39%) among frontline healthcare staff working during the COVID-19 pandemic. Although major depression developed during the pandemic, PTSD was more likely to be pre-existing. When assessing pandemic-related psychopathology, it is important to assess the onset and index event related to symptoms. Healthcare workers appear to have high rates of PTSD related to occupational and personal trauma, which warrants specific focus in service planning.
