49pc of ICU staff ‘have mental health issues’ due to Covid Top Story January 13, 2021 LONDON: Almost half of intensive care staff working during the coronavirus crisis are likely to be suffering from problem drinking, severe anxiety or post-traumatic stress disorder (PTSD), new research suggests. The study, from King’s College London and published in the journal Occupational Medicine, found poor mental health was common among intensive care unit (ICU) staff, and was more pronounced in nurses than in doctors or health workers on the ward. For the study, 709 healthcare workers from nine ICUs in England completed anonymous web-based surveys in June and July 2020.
