Nurses are the backbone of healthcare, especially during times of crisis like the COVID-19 pandemic. Yet, many nurses are facing an unseen battle with mental health conditions like post-traumatic stress disorder (PTSD), moral injury, and burnout. These conditions, often compounded by overwhelming workloads, inadequate support, and ethical conflicts, have led to a growing crisis in nurse retention. Nurses are leaving the profession in alarming numbers, leaving healthcare systems already struggling to cope with staffing shortages. Understanding the intersection of PTSD, moral injury, and burnout is crucial for addressing this crisis and finding sustainable solutions to keep nurses in the profession.

What is PTSD, Moral Injury, and Burnout?

Before diving into the consequences of these mental health conditions, it’s important to define them and understand how they manifest in nurses.

Post-Traumatic Stress Disorder (PTSD)

PTSD is a psychological condition triggered by experiencing or witnessing traumatic events. In the context of healthcare, PTSD is often seen in nurses who have worked in high-stress, high-risk environments, particularly during events like the COVID-19 pandemic. Nurses have been exposed to a series of traumatic experiences: caring for severely ill patients, witnessing death, and working under extreme pressure in overcrowded, under-resourced environments.

For nurses, PTSD symptoms can include:

• Intrusive memories (flashbacks or nightmares)
• Hypervigilance (constant state of alertness)
• Avoidance (avoiding reminders of traumatic experiences)
• Emotional numbness (detachment from others)

The impact of PTSD is not limited to mental health; it also affects physical health, job performance, and patient safety. Nurses with PTSD may experience sleep disturbances, chronic pain, fatigue, or memory problems. These symptoms can impair their ability to provide safe, quality care, leading to medication errors or missed diagnoses. The psychological toll can also lead to a higher risk of substance abuse or suicidal ideation.

Moral Injury

Moral injury refers to the psychological distress that occurs when individuals violate their moral or ethical beliefs. In nursing, this can happen when nurses are forced to make difficult decisions that conflict with their values, such as rationing care during resource shortages or witnessing suffering that they feel powerless to alleviate.

During the COVID-19 pandemic, nurses faced unprecedented ethical dilemmas:

• Isolation of patients: COVID-19 patients were often isolated from their families, leading to a sense of helplessness and guilt among nurses who had to manage the emotional and physical suffering of patients without family support.
• Patient deaths: Nurses were frequently the only ones with patients as they died, experiencing the trauma of witnessing patients die alone, without family members to comfort them. This experience often led to profound grief and feelings of inadequacy.
• Rationing of care: In some cases, nurses were forced to prioritize certain patients over others due to a shortage of resources, creating intense moral conflict.

Moral injury can cause lasting emotional harm, including guilt, shame, anger, and disillusionment. It is often harder to address than PTSD, because it involves a deep sense of moral or ethical violation, which can erode a nurse’s sense of identity and purpose in the profession.

Burnout

Burnout is a state of physical, emotional, and mental exhaustion caused by prolonged stress. It’s marked by feelings of:

• Emotional exhaustion: A sense of being drained and unable to cope.
• Depersonalization: A detachment from one’s job, patients, or colleagues.
• Reduced personal accomplishment: A feeling of ineffectiveness or failure in one’s professional role.

The COVID-19 pandemic intensified burnout in nurses, with long shifts, high patient loads, and constant exposure to traumatic situations. The added pressures of mandatory overtime, inadequate staffing, and lack of control over schedules exacerbated the sense of burnout. Nurses reported feeling overwhelmed, undervalued, and unsupported by their employers.

Burnout in nurses has serious consequences. It contributes to higher turnover rates, reduced job satisfaction, and increased absenteeism. In the long term, burnout can lead to physical and mental health issues, including chronic fatigue, depression, anxiety, and cardiovascular problems.

The Intersections: How PTSD, Moral Injury, and Burnout Relate

These three conditions—PTSD, moral injury, and burnout—are often not experienced in isolation. Rather, they intersect and compound one another, creating a vicious cycle that can be difficult to break.

• PTSD and Moral Injury: Nurses experiencing PTSD may also suffer from moral injury, especially if they’ve been forced into situations where they feel they’ve violated their own ethical standards. For example, a nurse who witnessed the death of a patient who was unable to be properly cared for due to overcrowding may experience both trauma from the patient’s death (PTSD) and guilt over not being able to provide adequate care (moral injury).
• Burnout and PTSD: The exhaustion caused by burnout can make PTSD symptoms worse. A nurse already suffering from anxiety and trauma may find it difficult to manage their workload, leading to further emotional exhaustion. Over time, this can contribute to an overall decline in mental and physical health.
• Moral Injury and Burnout: Nurses experiencing moral injury are more likely to feel disillusioned and emotionally detached from their work, which is a key component of burnout. The sense of having failed to meet their own ethical standards can lead to feelings of helplessness, frustration, and exhaustion.

Consequences of Untreated Mental Health Issues for Nurses

When PTSD, moral injury, and burnout go untreated, the consequences can be severe—not just for nurses, but for the healthcare system as a whole.

High Turnover and Retention Crisis

Untreated mental health conditions in nurses are a major factor driving the nurse retention crisis. According to recent studies, nearly half of young nurses in Alberta are leaving the profession before their 35th birthday. This rate is higher than the national average, with 47.7 nurses leaving for every 100 entering the profession in Alberta in 2022. The situation is particularly alarming because many nurses cite burnout, moral injury, and PTSD as reasons for their departure. 90% of nurses in Alberta report feeling burnt out, with many of them considering leaving the profession altogether.

The loss of experienced nurses not only impacts patient care but also increases the burden on remaining staff, contributing to a cycle of worsening burnout. Healthcare organizations, already facing staffing shortages, are struggling to retain the nurses who remain, leading to a “brain drain” in the profession.

Impact on Patient Care and Healthcare Systems

The consequences of untreated PTSD, moral injury, and burnout are not confined to the mental health of nurses; they also directly impact patient care. Nurses suffering from these conditions may have difficulty concentrating, making decisions, or communicating effectively. This can lead to an increase in medication errors, patient safety concerns, and decreased quality of care. The World Health Organization has linked burnout in healthcare workers to increased risk of medical errors and poor patient outcomes.

In addition to compromising care quality, the exodus of nurses is contributing to an overall shortage of healthcare workers, which will continue to affect patient treatment and increase wait times. Canada is projected to face a nurse shortage of over 117,000 by 2030, a crisis that has already begun to manifest in provinces like Alberta.

Organizational Strategies to Address Mental Health Issues in Nurses

To address the mental health crisis among nurses, healthcare organizations need to take comprehensive, organizational-level action. This requires not only supporting individual nurses but also creating a culture and infrastructure that prioritize mental health and well-being.

Improved Leadership and Organizational Support

One key strategy is to provide proper support and leadership. Studies have shown that the presence of strong leadership and peer support can significantly reduce the impact of PTSD in nurses. Nurse managers and leaders should be trained to recognize the signs of PTSD, burnout, and moral injury and offer resources for support. Additionally, ensuring that nurses have adequate staffing and manageable workloads can help mitigate these issues before they escalate.

Culture Change and Workplace Wellness

Healthcare organizations should foster a wellness culture that prioritizes the mental and physical well-being of nurses. This includes:

• Workplace flexibility: Reducing mandatory overtime, allowing for better work-life balance, and offering flexible schedules can help alleviate burnout.
• Adequate rest and recovery: Nurses need time to rest and recuperate, which can be achieved through proper staffing and scheduling.
• Support programs: Mental health resources, including counseling, peer support, and wellness programs, must be readily accessible. Building a network of support both within the workplace and in the community is crucial.

A Call to Action: The Need for Immediate Change

Nurses are essential to the healthcare system, and their mental health is directly tied to the quality of patient care. The mental health challenges faced by nurses, particularly PTSD, moral injury, and burnout, are not just individual issues—they are systemic problems that demand systemic solutions. Healthcare organizations must act urgently to support their nursing staff, provide adequate resources, and foster a culture of well-being.

Conclusion: Rebuilding a Sustainable Workforce

Addressing the mental health crisis among nurses is not just about improving individual well-being; it is about sustaining the healthcare workforce for the future. By addressing the root causes of PTSD, moral injury, and burnout, we can create a healthier, more sustainable workforce, ultimately leading to better outcomes for both nurses and patients. It’s time for healthcare organizations to take the mental health of their staff seriously—and act before it’s too late.
