Almost half of ICU staff battle mental health issues during pandemic — International study

An Imperial College London study found that of 515 healthcare staff working in intensive care units (ICUs) across seven countries, on average 48% of participants showed signs of mental health conditions like depression, insomnia and post-traumatic stress disorder (PTSD). Their mental health was assessed using a detailed questionnaire and a clinical scoring system.

The team also found a 40% increase in the conditions for those who spent more than six hours in personal protective equipment (PPE) over a course of a day, compared with those who didn't.

The study is the first to evaluate ICU workers' mental health during the COVID-19 pandemic. In line with the UK government's report on burnout in NHS staff published in June 2021, the researchers suggest that the high level of mental health conditions found among the ICU staff surveyed should inform local and national well-being policies.

Dr Ahmed Ezzat, lead author of the study and Honorary Clinical Fellow at Imperial College London, said: "This is a timely study which acts as a stark reminder of the personal challenges facing healthcare staff as a result of COVID-19. As within wider society, mental illness of healthcare staff still remains a taboo subject for some.

"Recent public campaigns have started the conversation, but we have a long way to go. COVID-19 has acutely exacerbated the issue, and our concern is how staff resilience has been exhausted and what national medium or long-term resources are set in place by policy makers to safeguard this workforce from severe mental illness.

"We have an opportunity to hold a national dialogue of healthcare leaders, stakeholders and governments around the world to address mental health within healthcare."

Dr Matthieu Komorowski, senior author of the study and Clinical Senior Lecturer in the Department of Surgery and Cancer at Imperial College London, said: "COVID-19 has impacted the physical and mental health of healthcare workers around the world. The large number of patients admitted to hospital at the height of the pandemic has put considerable demand and pressure on ICUs and staff.

“Although there has been much reporting on the mental health of frontline workers little has been done to assess the impact of the pandemic on those who were treating the sickest patients in ICU.

"This study shows the impact of working in ICU on staff's mental health. We saw high levels of depression, insomnia and PTSD. Factors such as individual isolation, loss of social support during lockdown, combined with a change in work pattern may have exacerbated these conditions.

"Work-related stress is well documented in healthcare workers and this has been worsened by the COVID-19 crisis. The results of this study suggest that all ICU staff should have access to early and effective mental health assistance as part of a wider staff health and well-being strategy. This is especially pressing as hospitals and governments prepare their workforce for potential further surges of COVID-19 patients."

During the height of the pandemic there were large intakes of patients admitted to ICUs, exceeding capacity. To manage demand, many hospitals have had to increase the ICU workforce via staff redeployment, with staff required to undertake duties that require different skills from their normal roles.

Although the mental health burden in healthcare workers caused by
COVID-19 has gained increasing attention, there has been a lack of data, especially relating to healthcare workers in ICU.

The researchers wanted to examine whether critical care staff experienced adverse mental health in a similar way to frontline healthcare workers, during the height of the COVID-19 pandemic.

The team recruited 515 healthcare workers working in ICUs in May 2020. They covered a range of roles such as nurses, junior and senior doctors, healthcare assistants and physiotherapists. Participants were from the UK (73), France (309), Italy (31), Taiwan (29), Belgium (2), Egypt (3) and China (68). They were recruited by word of mouth, emails and social media platforms.

Using a detailed questionnaire, the team asked participants questions on their well-being and anxieties. They then scored their responses using three different grading systems used in clinical settings to identify depression, PTSD and insomnia.

The team found that across the various countries explored, 37% of respondents exceeded the threshold for signs of depression, 78% for insomnia and 28% for PTSD.

The team also identified an increase in the scores in those who spent more than six hours in PPE over a course of a day. On average, there was a 40% increase in the depression score for those spending more than six hours in PPE compared with those who didn't and a 23% increase in the insomnia and PTSD scores, suggesting that mental health conditions amplify with longer time spent in PPE.

The authors also found that 57% of respondents declared feeling very or extremely worried about getting infected, while 21% were very or extremely worried about dying after catching the virus. Overall, 78% of respondents reported feeling at least a little numb about the loss of human lives, and most (89%) thought about these difficult experiences outside work.

Finally, 88% agreed that healthcare staff should be offered dedicated time off work once it was clinically safe to do so, and 85% were in favour of offering individual counselling sessions to healthcare workers.

The authors acknowledge there are some limitations to the study as respondents were self-selecting rather than randomly chosen, which could affect how representative this group was of ICU workers as a whole. Of those who responded, 11 said they had pre-existing mental health conditions. Despite this, the researchers suggest the data provides a useful indicator of mental well-being across ICU staff and the findings can be used to devise local and national policies to address this.

The global mental health burden of COVID-19 on critical care staff

Published British Journal of Nursing 10 June 2021

Abstract

Background
Although the mental health burden in healthcare workers caused by COVID-19 has gained increasing attention both within the profession and through public opinion, there has been a lack of data describing their experience; specifically, the mental wellbeing of healthcare workers in the intensive care unit (ICU), including those redeployed.

Aims
The authors aimed to compare the mental health status of ICU healthcare workers (physicians, nurses and allied health professionals) affected by various factors during the COVID-19 pandemic; and highlight to policymakers areas of staff vulnerabilities in order to improve wellbeing strategies within healthcare systems.

Methods
An online survey using three validated scales was conducted in France, the UK, Italy, Mainland China, Taiwan, Egypt and Belgium.

Findings
The proportion of respondents who screened positive on the three scales across the countries was 16–49% for depression, 60–86% for insomnia and 17–35% for post-traumatic stress disorder. The authors also identified an increase in the scores with longer time spent in personal protective equipment, female gender, advancing age and redeployed status.

Conclusion
The high prevalence of mental disorders among ICU staff during the COVID-19 crisis should inform local and national wellbeing policies.
