Throughout the COVID-19 pandemic, many health-care workers (HCWs) have worked extremely long hours in high-pressure environments. Additionally, they may have been exposed to trauma and/or faced moral dilemmas relating to challenges in the delivery of high-quality care, possibly due to a lack of experience or equipment, or as a result of low staffing levels1. These unprecedented circumstances are likely to increase the risk of mental health disorders such as post-traumatic stress disorder (PTSD) or depression, other anxiety disorders, substance misuse and suicide. HCWs caring for patients with COVID-19 are also at increased risk of infection, and by extension, have to contend with the risk of infecting their families. Moreover, some individuals, including those of Black, Asian and minority ethnic (BAME) background are at even higher risk of adverse outcomes and may therefore also be at increased risk of psychological issues. The risk of psychological harm is not restricted to frontline HCWs; in fact most HCWs, regardless of their speciality, are likely to have experienced notable challenges since the pandemic began, including changes to the way they work and, at times, being unable to deliver the quality of care they would normally. Whilst some HCWs will undoubtedly thrive in such stressful circumstances, it is imperative that managers of HCWs take measures to protect the mental health of staff as well as identify those who do experience psychological injuries, to ensure they are provided with appropriate evidence-based support or care.

The vast scientific literature on the psychological consequences of exposure to trauma shows that the two risk factors most strongly predictive of long-term mental health status are lack of post-trauma social support and exposure to stressors during recovery from trauma2. These stressors might be directly attributable to the trauma, for example, the death of a family member or co-worker, or secondary to the crisis, such as relationship difficulties3. The good news is that health-care managers can very strongly influence a HCW’s experience of being supported and their exposure to workplace pressures during the post-crisis period. Studies of HCWs dealing with previous infectious disease outbreaks show the powerful effect that supportive managers have on the mental health of their staff4, whereas evidence from military studies show that a phased return to ‘normal’ work is also beneficial.

Taken as a whole, available evidence suggests that protecting the mental health of HCWs requires consideration of six key elements. First, HCWs should be appropriately thanked. Appropriate acknowledgement of the challenging work undertaken can foster resilience5. This acknowledgement should also include recognition of potential psychological difficulties and provide information about support options available.

Second, given that avoidance is a key symptom of traumatic stress and this behaviour may manifest through distressed staff staying away from work, it is imperative that staff who do not turn up to work are contacted in case their non-attendance is indicative of poor mental health.

Third, as the COVID-19 pandemic begins to recede all HCWs should receive ‘return to normal work’ interviews. These should happen as staff begin the transition from crisis response roles back to the new normal and should be conducted by supervisors who, by virtue of experience or training, can confidently speak about mental health. They provide an opportunity for a supervisor to better understand a staff member’s experiences and can help foster an ‘it’s okay not to be okay’ approach to mental health. Such discussions have been shown to reduce absences due to sickness in other trauma-exposed occupations6.

Fourth, managers should pay particular attention to HCWs in high-risk groups, such as those with a BAME background, and junior or inexperienced staff who have been working above their expected level of competence. The abovementioned ‘return to normal work’ interview is again important here, as it can be used to identify the presence of pertinent stressors such as bereavement or feelings of being overwhelmed. Particular attention should be paid to staff who, during the crisis, have worked far beyond their usual role, for instance, an outpatient nurse who may have been required to care for a ventilated patient during the crisis. Strong evidence shows that additional stressors can have a very important impact on the mental health of people who have already suffered a traumatic experience7.

These unprecedented circumstances are likely to increase the risk of mental health disorders

Fifth, as recommended by the UK National Institute for Health and Care Excellence, anyone who has been exposed to a potentially traumatic event should be actively monitored, particularly those considered at higher risk of developing mental health problems. Although this type of monitoring forms part of good management, available evidence suggests that proactively asking such individuals about their mental health can increase the take-up of mental health care as has been found after terrorist incidents in the UK2. This monitoring could be achieved through the use of an anonymous, online self-check tool comprising a range of mental health measures giving tailored advice, such as self-help information or ways to access professional care. Such an anonymous approach is likely to increase the chance that HCWs will use the self-check tool.

Lastly, given the likelihood that HCWs have been exposed to morally distressing circumstances during the COVID-19 pandemic, most probably repeatedly, managers should help them to make sense of their experiences. Being able to develop meaningful narrative that does not blame themselves or others for what happened during the crisis is likely to reduce the risk of them suffering psychological harm. One evidence-based model that may prove useful is Schwartz rounds — a structured forum in which staff can discuss emotional and social aspects of work — which has been shown to help staff communicate better in both US and UK health-care settings.

Supporting the mental health of HCWs is not just morally justified — done well it should lower the risk of mental illness and maximize the opportunity for staff to experience psychological growth8 from overcoming the challenges faced during the pandemic. As described previously, the unwritten psychological contract between HCWs, their managers and the public has been that staff members will give their all to save lives and in return the nation does all it can to protect their mental health through the provision of proper support9. Although rapid access to effective evidence-based treatments will be needed for an important minority of HCWs as a result of the stressors experienced during the COVID-19 pandemic, a substantial evidence base supports the notion that health-care managers have a substantial role in protecting the mental health of their staff as well as in helping those that need additional care and support to access it.
