This multi-centre study has examined moral distress across a range of ICU professions for the first time in the UK and was conducted prior to the COVID-19 pandemic. Moral distress was present in all units and across professions, and levels of seniority. Despite the range of participants included, there was consistency in themes regarding causes of moral distress, responses to moral distress, and strategies for coping with it. Causes of moral distress most commonly related to situations where staff were providing care they thought was contrary to their patient’s interests and/or wishes, and in some cases causing them harm. An inability to provide treatment because of lack of resources, and an inability of senior staff to protect their juniors were also sources of moral distress. An overarching theme was a feeling of lack of agency or power to change the course of action and to do what they thought best for their patient. The multiple negative emotions engendered by this repeated experience can lead to withdrawal from engagement with patients and families, likely leading to poorer clinical care, and ultimately to withdrawal from intensive care as a career choice. Staff described a range of individualised coping mechanisms. In general, informal support mechanisms were preferred to more formal arrangements.
A lack of agency being central to the experience of moral distress is consistent with previous studies and conceptual debate.(11–15, 35, 36) However, these works have focussed on nursing populations and our study finds that a lack of agency is fundamental across ICU professions and not an element unique to nurses. This empirical finding supports the ongoing conceptual development of moral distress, providing further evidence to the significance of a lack of agency.
Situations relating to delivery of perceived futile care as a cause of moral distress among clinicians is a common finding in the international literature.(11, 28, 32) However, moral distress due to limited resources appeared more common in our study than in North America.(17, 32, 37) The only other UK study investigating causes of moral distress also noted limited resource availability, suggesting this between country difference could be a reflection of differences in healthcare systems and provision of critical care beds.(12, 30, 38, 39)
It is increasingly clear that moral distress is widespread and detrimental within intensive care.(14, 15, 26) A key question is therefore how to prevent and mitigate it. Given our finding of lack of agency as a cause of moral distress, one preventive strategy would be to improve agency and empower clinical staff to speak out. Hamric et al. report how a moral distress consultation service was successful in empowering staff in situations where they had felt unheard or powerless.(40) The authors also acknowledge that given the nature of intensive care practice it is almost inevitable that situations inducing moral distress will occur despite their consultation service. Participants in our study frequently recognised that moral distress may be inevitable in ICU practice. If we accept this inevitability, we also need to provide support for staff who experience it.
Our findings suggest that interventions aimed at combating moral distress require a tailored approach that recognises the individualistic nature of coping with moral distress. Accordingly, whether formal professional or senior support by structured debrief is used rather than informal talking to colleagues will depend on the type of incident. Individualised informal support appears the most common coping strategy and is often effective if it takes place in an organisational culture that provides a supportive environment. A common participant suggestion was to provide interventions that reflected this approach, such as facilitated informal discussion forums with a senior ICU professional. Our participants frequently reported that smaller ICUs were more supportive and more able to permit informal coping compared with larger ICUs. This is noteworthy as UK intensive care services move towards regionalisation with larger ICUs on a “hub and spoke” model to meet increasing care demands.(41) It may be possible to replicate the benefits of smaller units at larger ICUs by working in smaller, close-knit teams caring for “pods” of beds within the larger ICU. Embedding senior professionals who are nominated to facilitate discussion to cope with moral distress within these teams could be beneficial. Supporting effective coping could produce a positive feedback loop that encourages staff retention, therefore promoting a close-knit team and allowing formation of the staff relationships which appear so important in facilitating informal coping. Conversely, failure to control moral distress could produce a negative spiral due to its deleterious effects on career decisions.(9, 11, 17)
Our data suggest that moral distress influences career decisions with senior staff considering leaving intensive care and junior staff avoiding intensive care as a career due to moral distress, in keeping with previous studies linking moral distress to leaving the profession.(11, 17, 25) It is also notable that those with greater experience in ICU reported that their ability to cope with moral distress had improved through their career, alongside refinement of their coping strategies. It may be that junior staff struggling with moral distress can learn from these experienced seniors, supporting the suggestion of embedding senior professionals within smaller teams to facilitate informal discussion.
Optimising the working environment could also include improving non-clinical facilities. Extra stresses placed on staff by unsatisfactory parking, IT and payroll facilities appear to reduce the ability of staff to cope with moral distress and negatively impact staff wellbeing. Intensive care staff are a valuable resource and staff retention is key to delivering cost-effective and high-quality care.
This study is limited principally by selection bias. Those with strong negative experiences of moral distress may be more likely to volunteer, or conversely do not wish to relive their experiences by interview or have left the profession entirely. To mitigate any selection bias, we used purposive sampling by moral distress score and our sample is representative of the total sample in our questionnaire survey. It includes representation of all hospitals, a range of professions, seniority, age and gender. Furthermore, interviews were performed until not further themes emerged.
